Bidders are further urged to review sections 2-3 SUBCONTRACTS of the General Provisions. CAUTIONS This form will be used by the Agency to determine the percentage of work that the Bidder proposes to perform. Bidders are cautioned that failure to provide complete and correct information may result in rejection of the bid as non-responsive. Any bid that proposes perfor- mance of more than 50 percent of the work by subcontractors or otherwise to be performed by forces other than the Bidder's own organization will be rejected as non-responsive. Specialty items of work that may be so designated by the Engineer on the "Contractor's Proposal" are not included in computing the percentage of work proposed to be performed by the Bidder. INSTRUCTIONS The Bidder shall set forth the name and location of business of each and every subcontractor whom the Bidder proposes to perform work or labor or render service in or about the work or improvement, and every subcontractor licensed as a contractor by the State of Cali- fornia whom the Bidder proposes to specially fabricate and install any portion of the work or im- provement according to detailed drawings contained in the plans and specifications in excess of one-half of one percent (0.5%) of the Bidder's total bid or, in the case of bids or offers for the construction of streets and highways, including bridges, in excess of one-half of one percent (0.5%) or ten thousand dollars ($10,000) whichever is greater. Said name(s) and location(s) of -business of subcontractor(s) shall be set forth and included as an integral part of the bid offer. - The Designation of Subcontractors form must be submitted as a part of the Bidder's sealed bid. Failure to provide complete and correct information may result in rejection of the bid as non- responsive. Suppliers of materials from sources outside the limits of work are not subcontractors. The value of materials and transport of materials from sources outside the limits of work, as shown on the plans, shall be assigned to the Contractor or the Subcontractor as the case may be, that the Bidder proposes as installer of said materials. The value of material incorporated in any Subcon- tractor-installed bid item that is supplied by the Bidder shall be included as a part of the work that the Bidder proposes to be performed by the Subcontractor installing said item. When a Subcontractor has a Carlsbad business license, the number must be entered on the proper form. If the Subcontractor does not have a valid business license, enter "NONE" in the appropriate space. When the Bidder proposes using a Subcontractor to construct or install less than 100 percent of a bid item, the Bidder shall attach an explanation sheet to the Designation of Subcontractor form. The explanation sheet shall clearly apprise the City of the specific facts that show the Bidder proposes to perform no less than fifty percent (50%) of the work with its own forces. Determination of the subcontract amounts for purposes of award of the contract shall be deter- mined by the City Council in conformance with the provisions of the contract documents and the various supplemental provisions. The decision of the City Council shall be final.

If the Contractor fails to specify a Subcontractor, or specifies more than one Subcontractor for the same portion of the work to be performed under the Contract (in excess of one-half of 1 percent of the Contractor's total Bid), the Contractor shall be qualified to perform that portion itself, and shall perform that portion itself, except as otherwise provided in the Code. As provided in Section 4107, no Contractor whose Bid is accepted shall substitute any person as Subcontractor in place of the Subcontractor listed in the original Bid, except for causes and by procedures established in Section 4107.5. This section provides procedures to correct a clerical error in the listing of a Subcontractor . . I"\ • ., Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 63 of 247 Section 411 O provides that a Contractor violating any of the provisions of the Chapter violates the Contract and the Board may exercise the option either to cancel the Contract or assess the Con- tractor a penalty in an amount of not more than 1 O percent of the subcontract involved, after a public hearing. Should the Contractor fail to adhere to the provisions requiring the Contractor to complete 50 percent of the contract price with its own organization, the Agency may at its sole discretion elect to cancel the contract or deduct an amount equal to 1 O percent of the value of the work performed in excess of 50 percent of the contract price by other than the Contractor's own organization. The Board shall be the sole body for determination of a violation of these provisions. In any proceed- ings under this section, the prime contractor shall be entitled to a public hearing before the Board and shall be notified ten (10) days in advance of the time and location of said hearing. The determination of the City Council shall be final. 2-3.2 Additional Responsibility. The Contrac:tor shall give personal attention to the fulfillment of the Contract and shall keep the Work under its control. The Contractor shall perform, with its own organization, Contract work amounting to at least 50 percent of the Contract Price except that any designated "Specialty Items" may be performed by subcontract, and the amount of any such "Specialty Items" so performed may be deducted from the Contract Price before computing the amount required to be performed by the Contractor with its own organization. "Specialty Items" will be identified by the Agency in the Bid or Proposal. Where an entire item is subcontracted, the value of work subcontracted will be based on the Contract Unit Price. When a portion of an item is subcontracted, the value of work subcontracted will be based on the estimated percentage of the Contract Unit Price. This will be determined from A information submitted by the Contractor, and subject to approval by the Engineer. w Before the work of any Subcontractor is started, the Contractor shall submit to the Engineer for approval a written statement showing the work to be subcontracted giving the name and business of each Subcontractor and description and value of each portion of the work to be so subcon- tracted. 2-3.3 Status of Subcontractors. Subcontractors shall be considered employees of the Con- tractor, and the Contractor shall be responsible for their work. 2-4 CONTRACT BONDS. Before execution of the Contract, the Bidder shall file surety bonds with the Agency to be approved by the Board in the amounts and for the purposes noted below. Bonds issued by a surety, who is authorized to issue bonds in California, and whose bonding limitation shown in said circular is sufficient to provide bonds in the amount required by the Con- tract shall be deemed to be approved unless specifically rejected by the Agency. Bonds from all other sureties shall be accompanied by all of the documents enumerated in Code of Civil Proce- dure 995.660 (a). The Bidder shall pay all bond premiums, costs, and incidentals. Each bond shall incorporate, by reference, the Contract and be signed by both the Bidder and Surety and the signature of the authorized agent of the Surety shall be notarized. The Contractor shall provide a faithful performance/warranty bond and payment bond (labor and materials bond) for this contract. The faithful performance/warranty bond shall be in a sum not less than one hundred percent of the total amount payable by the terms of this contract. The Con- tractor shall provide bonds to secure payment of laborers and materials suppliers in a sum not less than one hundred percent of the total amount payable by the terms of this contract. ft ~, Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 64 of 247 • - - - Both bonds shall extend in full force and effect and be retained by the Agency during this project until they are released according to the provisions of this section. The faithful performance/warranty bond will be reduced to 25 percent of the original amount 30 days after recordation of the Notice of Completion and will remain in full force and effect for the one year warranty period and until all warranty repairs are completed to the satisfaction of the Engineer. The bonds to secure payment of laborers and materials suppliers shall be released six months plus 30 days after recordation of the Notice of Completion if all claims have been paid. All bonds are to be placed with a surety insurance carrier admitted and authorized to transact the business of insurance in California and whose assets exceed their liabilities in an amount equal to or in excess of the amount of the bond. The bonds are to contain the following documents: 1) An original, or a certified copy, of the un-revoked appointment, power of attorney, by laws, or other instrument entitling or authorizing the person who executed the bond to do so. 2) A certified copy of the certificate of authority of the insurer issued by the insurance commis- sioner. If the bid is accepted, the Agency may require a financial statement of the assets and liabilities of the insurer at the end of the quarter calendar year prior to 30 days next preceding the date of the execution of the bond. The financial statement shall be made by an officer's certificate as defined in Section 173 of the Corporations Code. In the case of a foreign insurer, the financial statement may be verified by the oath of the principal officer or manager residing within the United States. Should any bond become insufficient, the Contractor shall renew the bond within 1 0 days after receiving notice from the Agency. Should any Surety at any time be unsatisfactory to the Board, notice will be given the Contractor to that effect. No further payments shall be deemed due or will be made under the contract until a new Surety shall qualify and be accepted by the Board. Changes in the Work or extensions of time, made pursuant to the Contract, shall in no way release the Contractor or Surety from its obligations. Notice of such changes or extensions shall be waived by the Surety. 2-5 PLANS AND SPECIFICATIONS. 2-5.1 General.

If such changes are granted, they shall be made at a reduction in cost or no additional cost to the Agency. 3-2 CHANGES INITIATED BY THE AGENCY. 3-2.1 General. The Agency may change the Plans, Specifications, character of the work, or quantity of work provided the total arithmetic dollar value of all such changes, both additive and deductive, does not exceed 25 percent of the Contract Price. Should it become necessary to exceed this limitation, the change shall be by written Supplemental Agreement between the Con- tractor and Agency, unless both parties agree to proceed with the change by Change Order. Change Orders shall be in writing and state the dollar value of the change or established method of payment, any adjustment in contract time of completion, and when negotiated prices are in- volved, shall provide for the Contractor's signature indicating acceptance. 3-2.2 Payment. 3-2.2.1 Contract Unit Prices. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does not involve substantial change in character of the work from that shown on the Plans or specified in the Specifications, then an adjustment in payment will be made. This adjustment will be based upon the increase or decrease in quantity and the Contract Unit Price. If the actual quantity of an item of work covered by a Contract Unit Price and constructed in con- formance with the Plans and Specifications varies from the Bid quantity by 50 percent or less, payment will be made at the Contract Unit Price. If the actual quantity of said item of work varies from the Bid quantity by more than 50 percent, payment will be made per Section 3-2.2.2 or 3- 2.2.3 as appropriate. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does involve a substantial change in the character of the work from that shown on the Plans or specified in the Specifications, an adjustment in payment will be made per Section 3-2.4. 3-2.2.2 Increases of More Than 50 Percent. Should the actual quantity of an item of work cov- ered by a Contract Unit Price and constructed in conformance with the Plans and Specifications, exceed the Bid quantity by more than 50 percent, payment for the quantity in excess of 150 per- cent of the Bid quantity will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3. The Extra Work per Section 3-3, basis of payment, shall not include fixed costs. Fixed costs shall be deemed to have been recovered by the Contractor through payment for 150 percent of the Bid quantity at the Contract Unit Price. 3-2.2.3 Decreases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price, and constructed in conformance with the Plans and Specif ica- tions, be less than 50 percent of the Bid quantity, an adjustment in payment will not be made unless so requested in writing by the Contractor. If the Contractor so requests, payment will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3; however, in no case will payment be less than would be made for the actual quantity at the Con- tract Unit Price nor more than would be made for 50 percent of the Bid quantity at the Contract -Unit Price. ft '-J Revised 11/24/1 0 Contract Nos. 3957, 3643, 6302, 6303 Page 75 of 247 3-2.3 Stipulated Unit Prices. Stipulated Unit Prices are unit prices established by the Agency in the Contract Documents as distinguished from Contract Unit Prices submitted by the Contractor. Stipulated Unit Prices may be used for the adjustment of Contract changes when so specified in the Special Provisions. 3-2.4 Agreed Prices. Agreed Prices are prices for new or unforeseen work, or adjustments in Contract Unit Prices per Section 3-2.2, established by mutual agreement between the Contractor and the Agency. If mutual agreement cannot be reached, the Engineer may direct the Contractor to proceed on the basis of Extra Work in accordance per Section 3-3, except as otherwise spec- ified in Sections 3-2.2.2 and 3-2.2.3. 3.2.4.1 Schedule of Values. Prior to construction, Contractor shall provide a schedule of values for all lump sum bid items that shall be used for the purpose of progress payments. The prices shall be valid for the purpose of change orders to the project. 3.2.5 Eliminated Items. Should any Bid item be eliminated in its entirety, payment will be made to the Contractor for its actual costs incurred in connection with the eliminated item prior to notifi- cation in writing from the Engineer so stating its elimination. If material conforming to the Plans and Specifications is ordered by the Contractor for use in the eliminated item prior to the date of notification of elimination by the Engineer, and if the order for that material can not be canceled, payment will be made to the Contractor for the actual cost of the material. In this case, the material shall become the property of the Agency. Payment will be made to the Contractor for its actual costs for any further handling. If the material is returnable, the material shall be returned and payment will be made to the Contractor for the actual cost of charges made by the supplier for returning the material and for handling by the Contractor. Actual costs, as used herein, shall be A computed on the basis of Extra Work per Section 3-3. W 3-3 EXTRA WORK. 3-3.1 General. New or unforeseen work will be classified as "extra work" when the Engineer determines that it is not covered by Contract Unit Prices or stipulated unit prices. 3-3.2 Payment. 3-3.2.1 General. When the price for the extra work cannot be agreed upon, the Agency will pay for the extra work based on the accumulation of costs as provided herein. 3-3.2.2 Basis for Establishing Costs. (a) Labor. The costs of labor will be the actual cost for wages of workers performing the extra work at the time the extra work is done, plus employer payments of payroll taxes, workers com- pensation insurance, liability insurance, health and welfare, pension, vacation, apprenticeship funds, and other direct costs, resulting from Federal, State, or local laws, as well as assessments or benefits required by lawful collective bargaining agreements. The use of a labor classification which would increase the extra work cost will not be permitted unless the Contractor establishes the necessity for such additional costs. Labor costs for equip- ment operators and helpers shall be reported only when such costs are not included in the invoice for equipment rental. The labor cost for foremen shall be proportioned to all of their assigned work and only that applicable to extra work will be paid. - I'\ •;, Revised 11 /24/1 0 Contract Nos. 3957, 3643, 6302, 6303 Page 76 of 247 - - - Nondirect labor costs, including superintendence, shall be considered part of the markup of Sec- tion 3-3.2.3 (a). (b) Materials. The cost of materials reported shall be at invoice or lowest current price at which such materials are locally available and delivered to the job site in the quantities involved, plus sales tax, freight, and delivery. The Agency reserves the right to approve materials and sources of supply, or to supply materials to the Contractor if necessary for the progress of the Work. No markup shall be applied to any material provided by the Agency. (c) Tool and Equipment Rental. No payment will be made for the use of tools which have a replacement value of $200 or less. Regardless of ownership, the rates and right-of-way delay factors to be used in determining rental and delay costs shall be the edition of the, "Labor Surcharge and Equipment Rental Rates" pub- lished by CALTRANS, current at the time of the actual use of the tool or equipment. The right-of- way delay factors therein shall be used as multipliers of the rental rates for determining the value of costs for delay to the Contractor and subcontractors, if any. The labor surcharge rates published therein are not a part of this contract. The rental rates paid shall include the cost of fuel, oil, lubrication, supplies, small tools, necessary attachments, repairs and maintenance of any kind, depreciation, storage, insurance, and all inci- dentals. Necessary loading and transportation costs for equipment used on the extra work shall be included. If equipment is used intermittently and, when not in use, could be returned to its rental source at less expense to the Agency than holding it at the Work site, it shall be returned, unless the Con- tractor elects to keep it at the Work site, at no expense to the Agency. All equipment shall be acceptable to the Engineer, in good working condition, and suitable for the purpose for which it is to be used. Manufacturer's ratings and approved modifications shall be used to classify equipment and it shall be powered by a unit of at least the minimum rating rec- ommended by the manufacturer. The reported rental time for equipment already at the Work site shall be the duration of its use on the extra work. This time begins when equipment is first put into actual operation on the extra work, plus the time required to move it from its previous site and back, or to a closer site. (d) Other Items. The Agency may authorize other items which may be required on the extra work, including labor, services, material, and equipment. These items must be different in their nature from those required for the Work, and be of a type not ordinarily available from the Con- tractor or Subcontractors. Invoices covering all such items in detail shall be submitted with the request for payment. (e) Invoices. Vendors' invoices for material, equipment rental and other expenditures shall be submitted with the request for payment. If the request for payment is not substantiated by invoices or other documentation, the Agency may establish the cost of the item involved at the lowest price which was current at the time of the report. ft ~, Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 77 of 247 3-3.2.3 Markup.

The following percentages shall be added to the Contractor's costs and shall constitute the markup for all overhead and profits: 1) Labor .................................... 20 2) Materials ............................... 15 3) Equipment Rental ................... 15 4) Other Items and Expenditures .... 15 To the sum of the costs and markups provided for in this section, 1 percent shall be added as compensation for bonding. (b) Work by Subcontractor. When all or any part of the extra work is performed by a Sub- contractor, the markup established in Section 3-3.2.3(a) shall be applied to the Subcontractor's actual cost of such work. A markup of 10 percent on the first $5,000 of the subcontracted portion of the extra work and a markup of 5 percent on work added in excess of $5,000 of the subcon- tracted portion of the extra work may be added by the Contractor. 3-3.3 Daily Reports by Contractor. When the price for the extra work cannot be agreed upon, the Contractor shall submit a daily report to the Engineer on forms approved by the Agency. Included are applicable delivery tickets, listing all labor, materials, and equipment involved for that day, and other services and expenditures when authorized. Payment for extra work will not be made until such time that the Contractor submits completed daily reports and all supporting doc- uments to the Engineer. Failure to submit the daily report by the close of the next working day may waive any rights for that day. An attempt shall be made to reconcile the report daily, and it shall be signed by the Engineer and the Contractor. In the event of disagreement, pertinent notes shall be entered by each party to explain points which cannot be resolved immediately. Each party - shall retain a signed copy of the report. Reports by Subcontractors or others shall be submitted A through the Contractor. w The report shall: 1. Show names of workers, classifications, and hours worked. 2. Describe and list quantities of materials used. 3. Show type of equipment, size, identification number, and hours of operation, including loading and transportation, if applicable. 4.

The Engineer will promptly investigate conditions which appear to be changed conditions. If the Engineer determines that conditions are changed conditions and they will materially affect perfor- mance time, the Contractor, upon submitting a written request, will be granted an extension of time subject to the provisions of 6-6. If the Engineer determines that the conditions do not justify an adjustment in compensation, the Contractor will be notified in writing. This notice will also advise the Contractor of its obligation to notify the Engineer in writing if the Contractor disagrees. The Contractor's failure to give notice of changed conditions promptly upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith. The Contractor shall not be entitled to the payment of any additional compensation for any act, or failure to act, by the Engineer, including failure or refusal to issue a change order, or for the hap- pening of any event, thing, occurrence, or other cause, unless the Contractor shall have first given the Engineer due written notice of potential claim as hereinafter specified. Compliance with this section shall not be required as a prerequisite to notice provisions in Section 6-7.3 Contract Time Accounting, nor to any claim that is based on differences in measurement or errors of computation as to contract quantities. The written notice of potential claim for changed conditions shall be submitted by the Contractor to the Engineer upon their discovery and prior to the time that the Contractor performs the work giving rise to the potential claim. The Contractor's failure to give written notice of potential claim for changed conditions to the agency upon their discovery and bet ore they are disturbed shall constitute a waiver of all claims in connection therewith. The Contractor shall provide the City with a written document containing a description of the par- ticular circumstances giving rise to the potential claim, the reasons for which the Contractor be- lieves additional compensation may be due and nature of any and all costs involved within 20 working days of the date of service of the written notice of potential claim for changed condi- tions.

When the Contractor intends to pur- chase materials, fabricated products, or equipment from sources located more than 50 miles out- side the geographical limits of the Agency, an inspector or accredited testing laboratory (approved by the Engineer), shall be engaged by the Contractor at its expense, to inspect the materials, ft ~ Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 83 of 247 equipment or process. This approval shall be obtained before producing any material or equip- ment. The inspector or representative of the testing laboratory shall judge the materials by the requirements of the Plans and Specifications. The Contractor shall forward reports required by the Engineer. No material or equipment shall be shipped nor shall any processing, fabrication or treatment of such materials be done without proper inspection by the approved agent. Approval by said agent shall not relieve the Contractor of responsibility for complying with the Contract requirements. 4-1.3.3 Inspection by the Agency. The Agency will provide all inspection and testing laboratory services within 50 miles of the geographical limits of the Agency. For private contracts, all costs of inspection at the source, including salaries and mileage costs, shall be paid by the permittee. 4-1.4 Test of Material. Before incorporation in the Work, the Contractor shall submit samples of materials, as the Engineer may require, at no cost to the Agency. The Contractor, at its ex- pense, shall deliver the materials for testing to the place and at the time designated by the Engi- neer. Unless otherwise provided, all initial testing will be performed under the direction of the Engineer, and at no expense to the Contractor. If the Contractor is to provide and pay for testing, it will be stated in the Specifications. For private contracts, the testing expense shall be borne by the permittee. The Contractor shall notify the Engineer in writing, at least 15 days in advance, of its intention to use materials for which tests are specified, to allow sufficient time to perform the tests. The notice shall name the proposed supplier and source of material. If the notice of intent to use is sent before the materials are available for testing or inspection, or A is sent so far in advance that the materials on hand at the time will not last but will be replaced by W a new lot prior to use on the Work, it will be the Contractor's responsibility to renotify the Engineer when samples which are representative may be obtained. Except as specified in these Provisions, the Agency will bear the cost of testing of locally produced materials and/or on-site workmanship where the results of such tests meet or exceed the require- ments indicated in the Standard Specifications, Technical Specification, and any Supplemental Provisions. The cost of all other tests shall be borne by the Contractor. At the option of the Engineer, the source of supply of each of the materials shall be approved by the Engineer before the delivery is started. All materials proposed for use may be inspected or tested at any time during their preparation and use. If, after incorporating such materials into the Work, it is found that sources of supply that have been approved do not furnish a uniform product, or if the product from any source proves unacc:eptable at any time, the Contractor shall furnish approved material from other approved sources. If any product proves unacceptable after im- proper storage, handling or for any other reason it shall be rejected, not incorporated into the work and shall be removed from the project site all at the Contractor's expense. Compaction tests may be made by the Enginem and all costs for tests that meet or exceed the requirements of the specifications shall be borne by the Agency. Said tests may be made at any place along the work as deemed necessary by the Engineer. The costs of any retests made necessary by noncompliance with the specifications shall be borne by the Contractor. 4-1.5 Certification. The Engineer may waive materials testing requirements of the Specifica- tions and accept the manufacturer's written certification that the materials to be supplied meet those requirements. Material test data may be required as part of the certification. ft \.J Revised 11 /24/1 0 Contract Nos. 3Si57, 3643, 6302, 6303 Page 84 of 247 - - - ---------·-·------------------------- 4-1.6 Trade Names or Equals. The Contractor may supply any of the materials specified or offer an equivalent. The Engineer shall determine whether the material offered is equivalent to that specified. Adequate time shall be allowed for the Engineer to make this determination. Whenever any particular material, process, or equipment is indicated by patent, proprietary or brand name, or by name of manufacturer, such wording is used for the purpose of facilitating its description and shall be deemed to be followed by the words or equal. A listing of materials is not intended to be comprehensive, or in order of preference. The Contractor may offer any mate- rial, process, or equipment considered to be equivalent to that indicated. The substantiation of offers shall be submitted as provided in the contract documents. The Contractor shall, at its expense, furnish data concerning items offered by it as equivalent to those specified. The Contractor shall have the material tested as required by the Engineer to determine that the quality, strength, physical, chemical, or other characteristics, including durabil- ity, finish, efficiency, dimensions, service, and suitability are such that the item will fulfill its in- tended function. Test methods shall be subject to the approval of the Engineer. Test results shall be reported promptly to the Engineer, who will evaluate the results and determine if the substitute item is equivalent. The Engineer's findings shall be final. Installation and use of a substitute item shall not be made until approved by the Engineer. If a substitute offered by the Contractor is not found to be equal to the specified material, the Contractor shall furnish and install the specified material. The specified Contract completion time shall not be affected by any circumstance developing from the provisions of this section. The Contractor is responsible for the satisfactory performance of substituted items. If, in the sole opinion of the Engineer, the substitution is determined to be unsatisfactory in performance, ap- pearance, durability, compatibility with associated items, availability of repair parts and suitability of application the Contractor shall remove the substituted item and replace it with the originally specified item at no cost to the Agency. 4-1.7 Weighing and Metering Equipment. All scales and metering equipment used for propor- tioning materials shall be inspected for accuracy and certified within the past 12 months by the State of California Bureau of Weights and Measures, by the County Director or Sealer of Weights and Measures, or by a scale mechanic registered with or licensed by the County. The accuracy of the work of a scale service agency, except as stated herein, shall meet the standards of the California Business and Professions Code and the California Code of Regula- tions pertaining to weighing devices. A certificate of compliance shall be presented, prior to oper- ation, to the Engineer for approval and shall be renewed whenever required by the Engineer at no cost to the Agency. All scales shall be arranged so they may be read easily from the operator's platform or area. They shall indicate the true net weight without the application of any factor. The figures of the scales shall be clearly legible. Scales shall be accurate to within 1 percent when tested with the plant shut down. Weighing equipment shall be so insulated against vibration or moving of other oper- ating equipment in the plant area that the error in weighing with the entire plant running will not exceed 2 percent for any setting nor 1.5 percent for any batch . ..... fi.J Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 85 of 247 4-1.8 Calibration of Testing Equipment. Testing equipment, such as, but not limited to pres-- sure gages, metering devices, hydraulic systems, force (load) measuring instruments, and strain- measuring devices shall be calibrated by a testing agency acceptable to the Engineer at intervals not to exceed 12 months and following repairs, modification, or relocation of the equipment. Cal- ibration certificates shall be provided when requested by the Engineer. 4-1.9 Construction Materials Dispute Resolution (Soils, Rock Materials, Concrete, Mortar and Related Materials, Masonry Materials, Bituminous Materials, Rock Products, and Mod- ified Asphalts). In the interest of safety and public value, whenever credible evidence arises to contradict the test values of materials, the Agency and the Contractor will initiate an immediate and cooperative investigation. Test values of materials are results of the materials' tests, as de- fined by these Specifications or by the special provisions, required to accept the Work. Credible evidence is process observations or test values gathered using industry accepted practices. A contradiction exists whenever test values or process observations of the same or similar materials are diverse enough such that the work acceptance or performance becomes suspect. The inves- tigation shall allow access to all test results, procedures, and facilities relevant to the disputed work and consider all available information and, when necessary, gather new and additional in- formation in an attempt to determine the validity, the cause, and if necessary, the remedy to the contradiction. If the cooperative investigation reaches any resolution mechanism acceptable to both the Agency and the Contractor, the contradiction shall be considered resolved and the co- operative investigation concluded. Whenever the cooperative investigation is unable to reach res- olution, the investigation may then either conclude without resolution or continue by written noti- fication of one party to the other requesting thei implementation of a resolution process by com- mittee. The continuance of the investigation shall be contingent upon recipient's agreement and acknowledged in writing within 3 calendar days after receiving a request. Without acknowledge- ment, the investigation shall conclude without resolution. The committee shall consist of three State of California Registered Civil Engineers. Within 7 calendar days after the written request notification, the Agency and the Contractor will eiach select one engineer. Within 14 calendar days of the written request notification, the two selected engineers will select a third engineer. The goal in selection of the third member is to complement the professional experience of the first two engineers. Should the two engineers fail to select the third engineer, the Agency and the Con- tractor shall each propose 2 engineers to be the third member within 21 calendar days after the written request notification. The first two engineers previously selected shall then select one of the four proposed engineers in a blind draw. The committee shall be a continuance of the coop- erative investigation and will re-consider all available information and if necessary gather new and additional information to determine the validity, the cause, and if necessary, the remedy to the contradiction. The committee will focus upon the performance adequacy of the material(s) using standard engineering principles and practices and to ensure public value, the committee may provide engineering recommendations as necessary. Unless otherwise agreed, the committee will have 30 calendar days from its formation to complete their review and submit their findings. The final resolution of the committee shall be by majority opinion, in writing, stamped and signed. Should the final resolution not be unanimous, the dissenter may attach a written, stamped, and signed minority opinion. Once started, the resolution process by committee shall continue to full conclusion unless: 1. Within 7 days of the formation of the committee, the Agency and the Contractor reach an acceptable resolution mechanism; or 2. Within 14 days of the formation of the committee, the initiating party withdraws its written notification and agrees to bear all investigative related costs thus far incurred; or 3. At any point by the mutual agreement of the Agency and the Contractor. Unless otherwise agreed, the Contractor shall bear and maintain a record for all the investigative costs until resolution. Should the investigation discover assignable causes for the contradiction, the assignable party, the Agency or the Contractor, shall bear all costs associated with the investigation. Should assignable causes for the ·contradiction extended to both parties, the -~ '-J Revised 11/24/1 0 Contract Nos. 3957, 3643, 6302, 6303 Page 86 of 247 - - - - 4-2 investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation substantiate a contradiction without assignable cause, the inves- tigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation be unable to substantiate a contradiction, the initiator of the investigation shall bear all investigative costs. All claim notification requirements of the contract pertain- ing to the contradiction shall be suspended until the investigation is concluded. MATERIALS TRANSPORTATION, HANDLING AND STORAGE. The Contractor shall order, purchase, transport, coordinate delivery, accept delivery, confirm the quantity and quality received, prepare storage area(s), store, handle, protect, move, relocate, remove and dispose excess of all materials used to accomplish the Work. Materials shall be delivered to the site of the work only during working hours, as defined in Section 6-7.2, and shall be accompanied by bills of lading that shall clearly state for each delivery: the name of the Con- tractor as consignee, the project name and number, address of delivery and name of consignor and a description of the material(s) shipped. Prior to storage of any materials which have been shipped to or by the Contractor to any location within the Agency's boundaries the Contractor shall provide the Engineer a copy of lease agreements for each property where such materials are stored. The lease agreement shall clearly state the term of the lease, the description of ma- terials allowed to be stored and shall provide for the removal of the materials and restoration of the storage site within the time allowed for the Work. All such storage shall conform to all laws and ordinances that may pertain to the materials stored and to preparation of the storage site and the location of the site on which the materials are stored. Loss, damage or deterioration of all stored materials shall be the Contractor's responsibility. Conformance to the requirements of this section, both within and outside the limits of work are a part of the Work. The Engineer shall have the right to verify the suitability of materials and their proper storage at any time during the Work. SECTION 5 -UTILITIES 5-1 LOCATION. The Agency and affected utility companies have, by a search of known rec- ords, endeavored to locate and indicate on the Plans, all utilities which exist within the limits of the work. However, the accuracy and/or completeness of the nature, size and/or location of utili- ties indicated on the Plans is not guaranteed. Where underground main distribution conduits such as water, gas, sewer, electric power, tele- phone, or cable television are shown on the Plans, the Contractor shall assume that every prop- erty parcel will be served by a service connection for each type of utility. As provided in Section 4216 of the California Government Code, at least 2 working days prior to commencing any excavation, the Contractor shall contact the regional notification center (Under- ground Service Alert of Southern California) and obtain an inquiry identification number. The California Department of Transportation is not required by Section 4216 to become a member of the regional notification center. The Contractor shall contact it for location of its subsurface installations. The Contractor shall determine the location and depth of all utilities, including service connections, which have been marked by the respective owners and which may affect or be affected by its operations. If no pay item is provided in the Contract for this work, full compensation for such work shall be considered as included in the prices bid for other items of work. ft '-J Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 87 of 247 5-2 PROTECTION. The Contractor shall not interrupt the service function or disturb the sup- port of any utility without authority from the owner or order from the Agency. All valves, switches, - vaults, and meters shall be maintained readily accessible for emergency shutoff. Where protection is required to ensure support of utilities located as shown on the Plans or in accordance with Section 5-1, the Contractor shall, unless otherwise provided, furnish and place the necessary protection at its expense. Upon learning of the existence and location of any utility omitted from or shown incorrectly on the Plans, the Contractor shall immediately notify the Engineer in writing. When authorized by the Engineer, support or protection of the utility will be paid for as provided in Section 3-2.2.3 or 3-3. The Contractor shall immediately notify the Engineer and the utility owner if any utility is disturbed or damaged. The Contractor shall bear the costs of repair or replacement of any utility damaged if located as noted in Section 5-1 . When placing concrete around or contiguous to any non-metallic utility installation, the Contractor shall at its expense: 1. Furnish and install a 2 inch cushion of expansion joint material or other similar resilient material; or 2. Provide a sleeve or other opening which will result in a 2 inch minimum-clear annular space between the concrete and the utility; or 3. Provide other acceptable means to prevent embedment in or bonding to the concrete. Where concrete is used for backfill or for structures which would result in embedment, or partial embedment, of a metallic utility installation; or where the coating, bedding or other cathodic pro- tection system is exposed or damaged by the Contractor's operations, the Contractor shall notify the Engineer and arrange to secure the advice of the affected utility owner regarding the proce- dures required to maintain or restore the integrity of the system. 5-3 REMOVAL. Unless otherwise specified, the Contractor shall remove all interfering por- tions of utilities shown on the Plans or indicated in the Bid documents as "abandoned" or "to be abandoned in place". Before starting removal operations, the Contractor shall ascertain from the Agency whether the abandonment is complete, and the costs involved in the removal and disposal shall be included in the Bid for the items of work necessitating such removals. 5-4 RELOCATION. When feasible, the owners responsible for utilities within the area affected by the Work will complete their necessary installations, relocations, repairs, or replacements be- fore commencement of work by the Contractor. When the Plans or Specifications indicate that a utility installation is to be relocated, altered, or constructed by others, the Agency will conduct all negotiations with the owners and work will be done at no cost to the Contractor, except for man- hole frame and cover sets to be brought to grade as provided in the Standard Specifications for Public Works Construction, Section 301-1.6, 2006 Edition. Utilities which are relocated in order to avoid interference shall be protected in their position and the cost of such protection shall be included in the Bid for the items of work necessitating such relocation. After award of the Contract, portions of utilities which are found to interfere with the Work will be relocated, altered or reconstructed by the owners, or the Engineer may order changes in the Work to avoid interference. Such changes will be paid for in accordance with Section 3-2. -~ \iJ Revised 11 /24/1 0 Contract Nos. 3957,.3643, 6302, 6303 Page 88 of 247 - - - When the Plans or Specifications provide for the Contractor to alter, relocate, or reconstruct a utility, all costs for such work shall be included in the Bid for the items of work necessitating such work. Temporary or permanent relocation or alteration of utilities requested by the Contractor for its convenience shall be its responsibility and it shall make all arrangements and bear all costs. The utility owner will relocate service connections as necessary within the limits of the Work or within temporary construction or slope easements. When directed by the Engineer, the Contractor shall arrange for the relocation of service connections as necessary between the meter and prop- erty line, or between a meter and the limits of temporary construction or slope easements. The relocation of such service connections will be paid for in accordance with provisions of Section 3- 3. Payment will include the restoration of all existing improvements which may be affected thereby. The Contractor may agree with the owner of any utility to disconnect and reconnect in- terfering service connections. The Agency will not be involved in any such agreement. In conformance with Section 5-6 the Contractor shall coordinate the work with utility agencies and companies. Prior to the installation of any and all utility structures within the limits of work by any utility agency or company, or its contractor, the Contractor shall place all curb or curb and gutter that is a part of the work and adjacent to the location where such utility structures are shown on the plans and are noted as being located, relocated or are otherwise shown as installed by others. In order to minimize delays to the Contractor caused by the failure of other parties to relocate utilities that interfere with the construction, the Contractor, upon the Engineer's approval, may be permitted to temporarily omit the portion of work affected by the utility. If such temporary omission is approved by the Engineer the Contractor shall place survey or other physical control markers sufficient to locate the curb or curb and gutter to the satisfaction of the utility agency or company. Such temporary omission shall be for the Contractor's convenience and no additional compensa- tion will be allowed therefore or for additional work, materials or delay associated with the tempo- rary omission. The portion thus omitted shall be constructed by the Contractor immediately fol- lowing the relocation of the utility involved unless otherwise directed by the Engineer. 5-5 DELA VS. The Contractor shall notify the Engineer of its construction schedule insofar as it affects the protection, removal, or relocation of utilities. Said notification shall be included as a part of the construction schedule required in Section 6-1. The Contractor shall notify the Engineer in writing of any subsequent changes in the construction schedule which will affect the time avail- able for protection, removal, or relocation of utilities. The Contractor will not be entitled to damages or additional payment for delays attributable to utility relocations or alterations if correctly located, noted, and completed in accordance with Sec- tion 5-1. The Contractor may be given an extension of time for unforeseen delays attributable to unrea- sonably protracted interference by utilities in performing work correctly shown on the Plans. The Agency will assume responsibility for the timely removal, relocation, or protection of existing main or trunkline utility facilities within the area affected by the Work if such utilities are not iden- tified in the Contract Documents. The Contractor will not be assessed liquidated damages for any delay caused by failure of Agency to provide for the timely removal, relocation, or protection of such existing facilities. If the Contractor sustains loss due to delays attributable to interferences, relocations, or altera- tions not covered by Section 5-1, which could not have been avoided by the judicious handling of forces, equipment, or plant, there shall be paid to the Contractor such amount as the Engineer may find to be fair and reasonable compensation for such part of the Contractor's actual loss as was unavoidable and the Contractor may be granted an extension of time. ~ "\J Revised 11 /24/1 0 Contract Nos. 3957, 3643, 6302, 6303 Page 89 of 247 5-6 COOPERATION. When necessary, the Contractor shall so conduct its operations as to - permit access to the Work site and provide time for utility work to be accomplished during the progress of the Work. The Contractor shall coordinate with San Diego Gas & Electric (SDG&E), AT&T, and Time Warner Cable on the under9rounding of the 12 overhead poles. The Contractor shall include in the work schedule time requirements for the utility companies to perform the undergrounding once the conduits and appurtenances are installed. Undergrounding must be completed before overhead poles can be removed and the work completed. The Contractor shall coordinate with Crown Castle on the relocation of two (2) existing Cell Sites. One site is on an existing wood utility pole and the other is on an existing street light.

As a part of the Baseline Construction Schedule the Contractor shall prepare and submit to the Engineer a tabular listing of all of the activities, showing for each activity the identification number, the description, the duration, the early start, the early finish, the late start, the late finish, the total float, and all predecessor and successor activities for the activity described. 6-1.2.3 Bar Chart. As a part of the Baseline Construction Schedule the Contractor shall prepare and submit to the Engineer a chart showing individual tasks and their durations arranged with the tasks on the vertical axis and duration on the horizontal axis. The bar chart shall use differing texture patterns or distinctive line types to show the critical path. 6-1.2.4 Schedule Software. The Contractor shall use commercially available software equal to the Windows 2000 compatible "Suretrak" program by Primavera or "Project'' program by Microsoft Corporation to prepare the Baseline Construction Schedule and all updates thereto. The Contrac- tor shall submit to the Agency a CD-ROM data disk with all network information contained thereon, in a format readable by a Microsoft Windows 2000 system. The Agency will use a "Suretrak", "Project" or equal software program for review of the Contractor's schedule. Should the Contrac- tor elect to use a scheduling program other than the "Suretrak" program by Primavera or "Project'' program by Microsoft Corporation the Contractor shall provide the Engineer three copies of the substituted program that are fully licensed to the Agency and 32 class hours of on-site training by the program publisher for up to eight Agency staff members. The classes shall be presented on Mondays through Thursdays, inclusive, between the hours of 8:00 a.m. and 5:00 p.m. The on- site training shall be held at 1635 Faraday Avenue, Carlsbad, California. The dates and times of the on-site training shall be submitted to the Engineer for approval five working days before the start of the on-site training. The on-site training shall be completed prior to the submittal of the first Baseline Construction Schedule. 6-1.2.5 Schedule Activities. Except for submittal activities, activity durations shall not be shorter than 1 working day nor longer than 15 working days, unless specifically and individually allowed by the Engineer. The Baseline Construction Schedule shall include between 100 and 500 activi- ties, including submittals, interfaces between utility companies and other agencies, project mile- stones and equipment and material deliveries. The number of activities will be sufficient, in the judgment of the Engineer, to communicate the Contractor's plan for project execution, to accu- rately describe the project work, and to allow monitoring and evaluation of progress and of time impacts. Each activity's description shall accurately define the work planned for the activity and each activity shall have recognizable beginning and end points. 6-1.2.6 Float. Float or slack time within the schedule is available without charge or compensation to whatever party or contingency first exhausts it. 6-1.2.7 Restraints to Activities. Any submittals, utility interfaces, or any furnishing of Agency supplied materials, equipment, or services, which may impact any activity's construction shall be shown as a restraint to those activities. Time periods to accommodate the review and correction of submittals shall be included in the schedule . ..... ~, Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 91 of 247 6-1.2.8 Late Completion. A Baseline Construction Schedule showing a project duration longer than the specified contract duration will not be acceptable and will be grounds for determination of default by Contractor, per Section 6-4. 6-1.2.9 Early Completion. The Baseline Construction Schedule will show the Contractor's plan to support and maintain the project for the entire contractual time span of the project. Should the Contractor propose a project duration shorter than contract duration, a complete Baseline Con- struction Schedule must be submitted, reflecting the shorter duration, in complete accordance with all schedule requirements of Section 6-1. The Engineer may choose to accept the Contrac- tor's proposal of a project duration shorter than the duration specified; provided the Agency is satisfied the shortened Baseline Construction Schedule is reasonable and the Agency and all other entities, public and private, which interface with the project are able to support the provisions of the shortened Baseline Construction Schedule. The Agency's acceptance of a shortened du- ration project will be confirmed through the execution of a contract change order revising the project duration and implementing all contractual requirements including liquidated damages in accordance with the revised duration. 6-1.2.1 0 Engineer's Review. The Construction Schedule is subject to the review of the Engineer. The Engineer's determination that the Baseline Construction Schedule proposed by the Contrac- tor complies with the requirements of these supplemental provisions shall be a condition prece- dent to issuance of the Notice to Proceed by the Engineer. If the Engineer determines that the Construction Schedule does not meet the requirements of these specifications the Contractor shall correct the Construction Schedule to meet these specifications and resubmit it to the Engi- neer. Failure of the Contractor to obtain the Engineer's determination that the initial Construction Schedule proposed by the Contractor complies with the_ requirements of these supplemental pro- visions within thirty (30) working days after the date of the preconstruction meeting shall be - grounds for termination of the contract per Section 6-4. Days used by the Engineer to review the initial Construction Schedule will not be included in the 30 working days. The Engineer will review and return to the Contractor, with any comments, the Baseline Construc- tion Schedule within 15 working days of submittal. The Baseline Construction Schedule will be returned marked as per Sections 6-1.2.10.1 through 6-1.2.10.3. 6-1.2.10.1 "Accepted." The Contractor may proceed with the project work upon issuance of the Notice to Proceed, and will receive payment for the schedule in accordance with Section 6-1.8.1. 6-1.2.10.2 "Accepted with Comments." The Contractor may proceed with the project work upon issuance of the Notice to Proceed. The Contractor must resubmit the schedule incorporat- ing the comments prior to receipt of payment per Section 6-1 .8.1. I 6-1.2.10.3 "Not Accepted." The Contractor must resubmit the schedule incorporating the cor- rections and changes of the comments prior to receipt of payment per Section 6-1 .8.1. The Notice to Proceed will not be issued by the Engineer if the changes of the comments are not submitted as required hereinbefore and marked "Accepted" or "Accepted with Comments" by the Engineer. The Contractor, at the sole option of the Engineer, may be considered as having defaulted the contract under the provisions of Section 6-4 DEFAULT BY CONTRACTOR if the changes of the comments are not submitted as required hereinbefore and marked "Accepted" by the Engineer. 6-1.3 Preparation of Schedule Updates and Revisions. The Contractor shall meet with the Engineer during the last week of each month to agree upon each activity's schedule status and shall submit monthly updates of the Baseline Construction Schedule confirming the agreements ft \iJ Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 92 of 247 -no later than the fifth working day of the following month.

If delays are caused by unforeseen events beyond the control of the Contractor, such delays will entitle the Contractor to an extension of time as provided herein, but the Contrac- tor will not be entitled to damages or additional payment due to such delays, except as provided in 6-6.3. Such unforeseen events may include: war, government regulations, labor disputes, strikes, fires, floods, adverse weather or elements necessitating cessation of work, inability to obtain materials, labor or equipment, required extra work, or other specific events as may be further described in the Specifications. No extension of time will be granted tor a delay caused by the Contractor's inability to obtain materials unless the Contractor furnishes to the Engineer documentary proof. The proof must be provided in a timely manner in accordance with the sequence of the Contractor's operations and the approved construction schedule. If delays beyond the Contractor's control are caused by events other than those mentioned above, the Engineer may deem an extension of time to be in the best interests of the Agency. The Con- tractor will not be entitled to damages or additional payment due to such delays, except as pro- vided in Section 6-6.3. ft ~, Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 96 of 247 - - - - If delays beyond the Contractor's control are caused solely by action or inaction by the Agency, such delays will entitle the Contractor to an extension of time as provided in Section 6-6.2. 6-6.2 Extensions of Time. Extensions of time, when granted, will be based upon the effect of delays to the Work.

The resurfacing work requires the affected streets be closed for one day, usually from around 7:30 a.m. to 5 p.m. If your street is to be re- surfaced, you will be notified of the exact day 72 hours in advance by a flyer attached to your front door knob. If it is a street in your neighborhood, you will notice temporary "No Parking" signs on the affected streets with a specific date written on them. (PLEASE NOTE: weather conditions and other factors outside our control can sometimes cause work to be rescheduled at the last minute. If this happens, we will notify you as soon as possible of the new date.) To prepare for this street closure, we are asking neighbors to help. Here's how: • Park your car outside the affected area unless you plan to leave before 7 a.m. the morning the work starts. • If your street is affected, par~ your car in your driveway or garage ( off the street) if you aren't going to need it during these times. Cars left on a street posted "No Parking" will be towed at the owner's expense. • Avoid walking, biking and skateboarding on new roads until construction signs are removed. Please keep kids and pets off the new roadway the day of the resurfacing, too. Until it is dry, the road resurfacing material will stain your shoes, cars, carpets and floors. • During the day of the resurfacing, please try to keep the new road dry (monitor sprinklers, hoses and other water sources around your home). • Work will not affect your trash pickup. Please put trash out on your nor- mal day. • For the next few months, it is even more important to keep your car off resurfaced streets on street sweeping day. Street sweeping helps re- move small pebbles and grit from the newly paved roadways. (To see the street sweeping schedule, search "street sweeping" on the city website, www.carlsbadca.gov).

The description of a debris containment system, to be used during the cleaning of bar reinforcing steel and concrete and placing of shotcrete, as required to provide for public safety. The Engineer shall have 15 days to review and approve the QCP submittal after a complete plan has been received. No construction of shotcrete test panels shall be performed until the QCP is approved by the Engineer. Should the Engineer fail to complete the review within this time allow- ance, and if, in the opinion of the Engineer, the Contractor's controlling operation is delayed or interfered with by reason of the delay in approving the QCP, the delay will be considered a right of way delay in conformance with the specifications in Section 8-1.09, "Right of Way Delays," of the Standard Specifications. Preconstruction shotcrete test panels shall be constructed by the nozzlepersons and application crew scheduled to do the work, using equipment, materials, mixing proportions, ambient temper- atures and procedures proposed for the work. The preconstruction shotcrete test panels shall conform to the following: 1. One shotcrete test panel, of the size determined by the Contractor, shall be unreinforced and shall have 3 cores taken from it and tested for compressive strength. The compres- sive strength shall be the average strength of the 3 cores, except that, if any core should show evidence of improper coring, the core shall be discarded and the compressive strength shall be the average strength of the remaining cores. The test panel shall be identified and submitted to the Engineer with the test results including a description of the mixture, proportions, and ambient temperature. 2. One shotcrete test panel shall have the same (1) thickness, (2) bar size and quantity of bar reinforcement or other obstructions, and (3) positioning of bar reinforcement or ob- structions as the most heavily reinforced section of shotcrete to be placed. The test panel shall be square with the length of the sides equal to at least 3 times the thickness of the most heavily reinforced section of shotcrete to be placed, but not less than 30 inches. After a minimum 7 days of cure, the test panel shall be broken by the Contractor, in the presence of the Engineer, into pieces no larger than 1 o inches in greatest dimension. The surfaces of the broken pieces shall be dense and free of laminations and sand pockets, and shall verify the bar reinforcement or other obstructions are completely encased. 3. Both test panels shall be cured under conditions similar to the actual work. 4. At the option of the Contractor, cores to be used for determining the compressive strength may be taken from the reinforced test panel described above instead of making a separate unreinforced test panel as described above. The compressive strength shall be the aver- age strength of the 3 cores, except that, if any core should show evidence of improper coring or contains bar reinforcement or other obstructions, the core shall be discarded and the compressive strength shall be the average strength of the remaining cores. If cores ft ~, Revised 11 /24/1 0 Contract Nos. 3957, 3643, 6302, 6303 Page 205 of 247 are taken from the reinforced test panel, the panel shall not be broken into pieces, as described above, until it has cured tor a minimum of 14 days.

The test panels shall resemble in appearance the texture, pattern, surface relief, strata line detail, and staining treatment of the project references, and the color shall closely match existing rock formations on the site. If ordered by the Engineer, additional test panels shall be constructed and finished until the specified finish, texture, and color are obtained, as determined by the Engineer. The test panels approved by the Engineer shall be used as the standard of comparison in deter- mining acceptability of architectural treatment for final shotcrete surfaces. -~ ~, Revised 11/24/10 Contract Nos. 3957, 3643, 6302, 6303 Page 207 of 247 CONSTRUCTION, SHOTCRETE SCULPTING Contractor's qualifications to perform the architectural treatment (textured shotcrete) work. The Contractor shall furnish evidence of at least 1 O years' experience to the Engineer, including, but not limited to, project references, dates, names, phone numbers, and color photos. The layout of strata lines shall only be perform,~d on walls fully constructed from top to bottom of the sculpted wall. This also applies to the full length of the wall. No sectional layout, sculpting, or staining work will be allowed as the wall is constructed in sections. Sculpting and staining personnel responsible for construction of the test panels shall be the same personnel used to sculpt and stain the wall throughout the duration of the project. The layout of strata lines throughout the shotcrete surface shall be performed in 2 stages. The Contractor shall notify the Engineer not less than 3 days prior to the first stage. The first stage shall consist of applying high visibility paint to the wall face to illustrate the strata line patterns for approval by the Engineer. The same personnel who will sculpt the wall face shall perform the layout of the primary and secondary strata lines .. The first stage shall be approved by the Engineer prior to beginning the second stage. The second stage shall consist of installing reinforcing support parallel to the primary strata lines. After the second stage is approved by the Engineer, shotcrete shall be applied in conformance with "Shotcrete," of these special provisions. The sculpting personnel shall direct the amount of shotcrete to be applied during the sculpting operation to provide the desired finished architectural detail and relief. ~ Sculpted shotcrete shall have non-repetitive patterns or contours, to prevent creation of repetitive secondary shadowing. Areas to receive surface texture that do not exhibit the surface specified shall be replaced so as to exhibit the specified texture. The Engineer will determine acceptability. The test panels approved by the Engineer shall be used as the standard of comparison in deter- mining acceptability of architectural treatment for textured shotcrete surfaces. PREPARE AND STAIN TEXTURED SHOTCRETE General This work shall consist of preparing and staining textured shotcrete surfaces where shown on the plans in conformance with the provisions in Section 59-6, "Painting Concrete," of the Standard Specifications and these special provisions.

It shall also demonstrate the colors that may be apparent from aging, such as staining from oxidation, rusting and/or organic staining from soil and/or veg- etation. Test Panels Two test panels constructed and approved in conformance with the requirements in "Architectural Treatment (Textured Shotcrete)" of these special provisions shall be prepared and stained as specified herein. All texture approved shotcrete test panels do not need to be prepared and stained. A representative sampling from the set of texture-approved test panels for shotcrete shall be selected by the Engineer for the Contractor to prepare and stain. The selected test panels shall be constructed, finished, and stained with the materials, tools, equipment, personnel, and methods to be used in constructing, finishing, and staining the shotcretesurfaces. Additional test panels may be ordered by the Engineer until the specified colors, shading, flecking and veining are obtained. The personnel who prepare and stain the test panels shall be the same personnel used to prepare and stain textured shotcrete surfaces. The Contractor shall provide documentation of stain oper- ation employees names to the Engineer. Following inspection, review and acceptance of the completed test panels by the Engineer, ap- proval will be given in writing by the Engineer. The approved stained test panels shall be sup- ported in a vertical position and left at the construction site for viewing. · Each test panel shall be exposed to direct sunlight for a minimum period of 7 calendar days after all colors are applied.

Please refer to the appropriate sections of the report for complete conclusions and recommendations. In the event of a conflict between this summary and the report, or an omission in the summary, the report shall prevail. • The El Camino Real Road is proposed to be improved by widening to full arterial with a design TI value equal to 9 between Chestnut A venue and Tamarack A venue in the City of Carlsbad, California. • The improved subject road will consist of 6 travel lanes (3 northbound/3 southbound -106 feet improved width with 126 feet right of way width) 8-foot bike lanes on both sict~s of the street, 18 foot wide landscaped median island and 10 foot wide parkways consisting of a 5 foot sidewalk and 5 foot native vegetation. • Field investigation included 1 1 exploratory borings located generally along the proposed road realignment and 4 hand auger holes located within the channel along the east side of the existing road alignment. Seven cores were obtained at planned locations within the subject road existing asphalt concrete pavement. The cored existing asphalt concrete pavement sections showed average asphalt concrete (AC) and aggregate base (AB) thicknesses of 5.1 inch each. Bulk and relatively undisturbed samples were obtained from the exploratory borings and hand augers for further laboratory testing. •Laboratory tests results yielded R-values of 8, 9, and 13. An average R-value of 10 was chosen for design. • Based on the design TI value of 9, an R-value of 10, and a 20 year design period a 6 inch thick rubberized hot mix AC and an 18 inch thick AB are recommended for the new asphalt concrete pavement section. However, the AB thickness may be reduced to I 1.5 inches with the installation of Tensar BX 1200 geogrid at the design subgrade elevation and Glassgrid mesh 8502 installed at the design AB elevation. • Contingent on the City approval, a 1.8 inch thick rubberized hot mix AC with Glassgrid mesh 8502 installed at the existing AB elevation will provide the required overlay for the existing AC for a IO year design period. However, a 4.1 inch thick rubberized hot mix overlay with Glassgrid mesh 8502 installed at the existing AB elevation will be required for a 15 year design period. • The sloughed and the failed slopes of the earth fill road embankment may be restored to their initial inclination of about 1: 1 (H: V) by over-excavating the sloughed and the failed slopes and grade restore the initial inclination with reinforced earth per figure 4 herein. • 1.5: 1 (H:V) cut slopes may be constructed in formational material along the sides of the subject road. • All backfill material should be compacted to a minimum 90 percent relative compaction. The upper one (1) foot of backfill beneath the pavement section should be compacted to 95 - percent relative compaction. In addition, two-sack slurry back fill or as deemed appropriate - - • by the utility owner should comprise the top foot of compacted fill to achieve finish grade in utility trenches. Based on the results of the field explorations and engineering analyses, it is TE-USL's opinion that the proposed construction is feasible from a geotechnical standpoint, provided that the recommendations in this report are incorporated into the design plans and implemented during construction. The above summary and conclusions are a general synopsis of the scope of work, findings and recommendations for the proposed El Camino Real Road widening project. Please refer to the pertinent sections of the geotechnical engineering investigation report for complete findings and recommendations. - TABLE OJ? CONTENTS Page 1.

El Camino Real Road Widening 1. INTRODUCTION Contract No.: 103582 March 28, 2006 Revised May 31, 2006 This report presents the results of the geotechnical engineering investigation for the proposed El Camino Real Road Widening improvements between Chestnut Avenue and Tamarack Avenue in the City of Carlsbad, California. The location of the subject project is presented on Figure 1, Site Location Map. The purpose of this study was two fold. Firstly, to evaluate pavement and subsurface conditions of the existing road and provide recommended pavement structural section based on the provided traffic index and subgrade conditions. Secondly, to evaluate pavement embankment slope stability and the need for remedial grading and/or ground improvements. This report summarizes the data collected and presents our findings, conclusions, and recommendations. 2. SCOPE OF SERVICES Our scope of services for this project consisted of the following tasks: e Review of readily available background data, including in-house geotechnical data, geotechnical literature, geologic maps, topographic maps, and seismic hazard maps and literature relevant to the subject site. • Conduct a site reconnaissance to observe the general road, abutting areas and existing channel conditions, and to select boring locations. • Perform two field exploratory programs to assess and characterize existing conditions. The first program included drilling, logging, and soil sampling of 11 exploratory borings located generally along the alignment and east shoulder of the proposed roadway improvements to depths up to approximately 30 feet below the existing grade. The program included coring the asphalt concrete pavement at seven locations along the subject road alignment. The second program included hand augering, logging and sampling of 4 exploratory holes generally located within the existing channel along the eastern side of the subject road to depths up to approximately 6 feet below the existing grade. Soil samples obtained from the field exploration programs were transported to our in-house laboratory for further testing. • Engineering evaluation of the geotechnical data collected to develop relevant geotechnical recommendations for the design and construction of the proposed improvements. Specifically addressing the following items: • Evaluation of pavement and subgrade conditions of the existing road and provide recommendation for pavement structural section based on the City of Carlsbad street design criteria and in-situ subgrade conditions. Recommendation for pavement structural section includes alternative subgrade treatment to reduce pavement section thickness. • Evaluation of existing pavement embankment slope stability, and provide recommendations for remedial grading and/or ground improvements. • Determination of seismic design parameters in accordance with chapter 16 of the 2001 California Building Code (CBC). 1 - • - -, , El Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 • Recommendations for utility trench backfill, and design of suitable foundation systems for light poles including allowable bearing capacity, lateral resistance, and settlement estimates. • Preparation of this report, including reference maps and graphics, summarizing the data collected and presenting our findings, conclusions, and geotechnical recommendations for the design and construction of the proposed development. 3. SITE DESCRIPTION The site for the proposed El Camino Real Road Widening improvements is that portion of the subject road and its east side abutting chatmel extending between Chestnut A venue and Tamarack Avenue, in the City of Carlsbad, California. The subject site is delineated by residences to the west, and vacant land to the east, except for approximately the northern 1000 feet where a row of residences are next to the east side of road. The abutting channel 6ettom is densely vegetated by various shrubs, trees, and bushes. At the time of our site visit the channel was surface dry. The existing road consists of 6 travel lanes including 3 northbound and 3 southbound lanes separated by a paved median at1d bike lanes on each side of the road. The asphalt concrete pavement exhibits several areas of fine alligator cracks especially at the northern portion of the subject road. The 5 foot wide concrete paved sidewalk on the east side of the road shows some distress at various locations along its length. The approximately 5 to 10 foot wide eastern earth shoulder of the pavement embankment has tension cracks and also signs of surface water scour at several locations along its length. The eastern slope of the pavement earth embankment exhibits several distress areas among which sloughing and slope failure at two locations situated approximately along the middle third of the subject road, (see Figure 2, Plot Plan). The lots to the west slope toward the subject road. Signs of surface slope wash were observed at several locations along the toe of the slope. Existing grades along the subject road alignment range from approximately 286 feet above mean sea level (AMSL) at the north end (intersection with Chestnut Avenue) down to approximately 77 feet AMSL at the south end (intersection with Tamarack Avenue). General topography in the vicinity of the site is also shown on Figure 2, Plot Plan. 4. PROPOSED IMPROVEMENTS El Camino Real is a major north/south roadway serving as a vital parallel circulation element to 1-5 for the cities of Encinitas, Carlsbad and Oceanside. Based on the El Camino Real Widening, Scope of Work, prepared by Benyman & Henigar, dated September 28, 2005, it is proposed that this project entails widening of El Camino Real Road between Chestnut A venue and Tamarack A venue to full prime arterial standards within the City of Carlsbad, California. The improved subject road will consist of 6 travel lanes (3 northbound/3 southbound -106 feet improved width with 126 feet right of way width) 8-foot bike lanes on both sides of the street, 18 foot wide landscaped median island and 10 foot ·wide parkways consisting of a 5 foot sidewalk and 5 foot native vegetation. 2 ' i i \. i I t. i ! l L i ,--- El Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 5. FIELD EXPLORATIONS AND LABORATORY TESTING 6. 5.1. Field Explorations The soil and groundwater conditions beneath the site were explored by drilling, logging, and sampling of 11 exploratory borings located generally along the proposed realignment to depths up to approximately 30 feet below the existing grade. The borings were drilled using a truck mounted 8-inch-diameter hollow-stem auger drill. In addition, 4 hand auger holes located within the channel along the road alignment were bored, logged, and sampled to depths up to approximately 6 feet below the existing grade. Before starting our field exploration program, a field reconnaissance accompanied by the City of Carlsbad representative ,vas conducted to observe site conditions and I]1ark the locations of the planned explorations. As required by the law, Underground Service Alert was notified of the locations of our exploratory borings 48 hours prior to drilling. Details of the explorations and the logs of the borings are presented in Appendix A. The approximate locations of the exploratory borings and hand auger holes are shown on Figure 2, Plot Plan. 5.2. Laboratory Testing Laboratory tests were performed on selected samples obtained from the borings and hand auger holes to aid in the soil classification and to evaluate the engineering properties of the foundation soils. The following tests were performed: • In-situ moisture content and dry density:, • Particle-size distribution; • Percent finer than sieve No. 200; • Atterberg limits; • Maximum density and optimum moisture content; • Direct shear; and • R-value Testing was performed in general accordance with applicable ASTM standards and California Test Methods. The laboratory test results are presented in Appendix B. Details of the laboratory-testing program are also included in Appendix B. GEOLOGY 6.1. Geologic Setting The site is located on the coastal plain of San Diego County within the Peninsular Ranges geomorphic province. This province is characterized by northwest-trending mountain ranges bordered by relatively straight-sided, sediment-floored valleys. The northwest trend is also reflected in the direction of the dominant geologic structural features, which consist of 3 - - - - - - EI Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 no1thwesHrending faults and fault zones. Two major northwest-trending fault zones traverse the San Diego metropolitan and the inland county areas: the Rose Canyon fault zone on the south and the Elsinore fault zone on the east. The Peninsular Ranges geomorphic province is located within what was fom1erly known as the Southern California Batholith, but is now termed the Peninsular Ranges Batholith. This batholith forms the core of the Peninsular Ranges, which extends from the Los Angeles Basin in the north to the tip of Baja California, Mexico in the south. The Peninsular Ranges Batholith is a major link in the chain oflate Mesozoic batholiths that rim the Pacific Basin. The Peninsular Ranges Batholith is a large igneous complex consisting of many well-defined plutons ranging in exposed diameter from a few hundred yards to nearly 30 miles. Igneous rock types range .from peridotite to granite with granodiorite and tonalite being the most common. The granites are exposed in the central and interior portions of the region. - The site is located within the near-coastal portion of the Peninsular Ranges Geomorphic Province of California. The near-coastal areas of the province in San Diego County are typically made up of shallow westward dipping sediments that form low mesas which are dissected by west-draining stream channels. According to information obtained in our investigation, the site is underlain by alluvium deposited on the relatively flat lying Tertiary- age sandstone sedimentary materials. 6.2. Geologic Materials Geologic materials encountered during the subsurface explorations consist in general of fill and alluvium materials overlying weathered Santiago Formation. Generalized descriptions of the units encountered in our field exploration are provided below. Detailed descriptions of the earth materials encountered in our exploration are presented on the boring logs in Appendix A. 6.2.1. Fill Fill was encountered in all the exploratory borings and hand auger holes other than hand auger hole 1, HA-1. The fill soils were in general light brown, damp, silty sand, clayey sand, and/or sandy clay, dense or soft to firm in consistency. The depth of fill ranged in thickness between 2 to 15 feet, approximately. 6.2.2. Alluvium Alluvial soils were encountered in borings 1, 3, 4, 7, 8, and 9, and hand auger holes 1, and 4. The alluvium generally consisted of light brown sandy clay/clayey sand that was moist and medium soft to stiff in consistency. As observed in our borings, the alluvium depth ranged up to approximately 30 feet below the existing grade. 4 \. i-i El Camino Real Road Widening 6.2.3. Santiago Formation Contract No.: 103582 March 28, 2006 Revised May 31, 2006 Santiago Formation was encountered in borings 5, 6, 7, 8, 10, 11, and hand auger hole 3 at depths ranging approximately between 2 to 15 feet. The formation is moderately . weathered at contact and was obsc:rved to be light olive brown silty sand and silty clay, weakly cemented, friable to stiff, and in a damp to moist state. The depth to the Santiago Formation appears to increase toward the east. 6.3 Groundwater Perched groundwater was observed in hand auger holes 1 and 4 at a depth of approximately 4 feet below existing grade. It is anticipated that this water is retained in low channel bed areas above the lower laying relatively impervious layers, since other deeper borings-did not encounter groundwater. However, it should be noted that groundwater conditions may vary due to different seasonal precipitations, channel flow, and other factors. 6.4. Faults The numerous faults in southern California include active, potentially active, and inactive faults. As used in this report, the definitions of fault terms are based on those developed for the Alquist-Priolo Special Studies Zones Act of 1972 and published by the California Division of Mines and Geology (Hart and Bryant, 1997). Active faults are defined as those that have experienced swface displacement within Holocene time (approximately the last 11,000 years) and/or have been included within any of the state-designated Earthquake Fault Zones (previously known as Alquist-Priolo Special Studies Zones). Faults are considered potentially active if they exhibit evidence of surface displacement since the beginning of Quaternary time (approximately two million years ago) but not since the beginning of Holocene time. Inactive faults are those that have not had surface movement since the beginning of Quaternary time. 6.4.1. Active Faults The closest known active fault to the site is the Rose Canyon fault zone, located approximately 6 miles from the site. Other important active faults in the San Diego area include Elsinore-Julian, Newport-Inglewood, Coronado Bank, and Elsinore- Temecula fault zones. These fault zones are located approximately 23 miles, 6.5 miles, 22 miles, and 23 miles from the site, respectively. The San Andreas Fault, which is generally considered to be capable of generating the largest earthquake in California, is located approximately 64 miles from the site. :5 - - - - • ! El Camino Real Road Widening 6.5. Geoseismic Hazards 6.5.1. Fault Rupture Contract No.: 103582 March 28, 2006 Revised May 31, 2006 The site is not located within any Earthquake Fault Zone delineated by the State of California for the hazard of fault surface rupture. The surface traces of any active or potentially active faults are not known to pass directly through, or to project toward the site. Therefore, the potential for surface rupture due to faulting occurring beneath the site during the design life of the proposed roadway is considered low. 6.5.2. Seismic Shaking The site is located in a seismically active area, as is the maJonty oC southern California. The most significant seismic hazard at the site is considered to be shaking caused by an eaiihquake occurring on a nearby or distant active fault. Active faults within a 62-mile radius of the site include the Rose Canyon, Coronado Bank, Newport-Inglewood (offshore segment), Elsinore (Julian, Temecula, Glenn Ivy, and Coyote Mountain, segments), Earthquake Valley, San Jacinto (Coyote Creek in Los Angeles, Anza and Borrego Segment), and Palos Verdes faults. 6.5.3. Liquefaction and Seismically-induced Settlement Liquefaction of soils can be caused by ground shaking during earthquakes. Research and historical data indicate that loose, relatively clean granular soils are susceptible to liquefaction and dynamic settlement, whereas the stability of the majority of clayey silts, silty clays and clays is not adversely affected by ground shaking. Liquefaction is generally known to occur in saturated cohesionless soils at depths shallower than approximately 50 feet. Dynamic settlement due to earthquake shaking can occur in both dry and saturated sands. The site is underlain predominately by relatively dense Santiago Formation overlain by shallow, fine-grained, alluvial deposits, without a !:,'TOundwater table, which is not considered to be subject to liquefaction. Therefore, the potential for liquefaction and the associated ground defonnation occurring beneath the site is considered low. 6.5.4. Subsidence The site is not located in an area of known ground subsidence due to the withdrawal of subsurface fluids. Accordingly, the potential for subsidence occurring at the site due to the withdrawal of oil, gas, or water is considered remote . 6 El Camino Real Road Widening 6.5.5. Tsunamis, f nundation Seiches, and Flooding Contract No.: 103582 March 2R, 2006 Revised May 31, 2006 The project site is located at an elevation ranging from approximately 77 to 286 feet AMSL. Therefore, tsunamis (seismic sea \vaves) are not considered a hazard at the site. The site is not located downslope of any large body of water that could affect the site in the event of an earthquake-induced failure or seiche ( oscillation in a body of v,rater clue lo earthquake shaking). 7. EXJSTING ROAD CONDITIONS 7.1. Pavement Section The ex1stmg pavement was cored at seven researched/planned locations, depicted as B-6 through B-12 on Figure 2, Plot Plan. The cored pavement sections were found to consist of a layer of asphalt concrete (AC) supported on silty sandy gravel aggregate base (AB Class 11). The observed total pavement section thickness as well as the thickness of the J\.C and AB components at each coring location arc presented in Table I, Existing Pavement Sections. TABLE 1 E_~i_~ting Pav~ment Sections 6 7 8 9 10 11 12 Average 6.5 55 4.0 4.0 50 55 5.0 5 1 50 4.5 4.5 5.0 5.0 6.0 6.0 5 1 ---~ ---- 11.5 10.0 8.5 90 10.0 11.0 11.0 10.2 ---------------==-------· Approximately l foot thick light brown, damp, medium dense silty sand \Vas observed beneath th<: pavement at all con:J locations except at B-6 and 13-l I. 7.2. Eastern Slope of Pavement Earth Embankment As described in Section 3., the eastern slope of the pavement earth embankment, which forms the western slope of the abutting channel, exhibits several distress areas among which sloughing and slope failure at two locations situated approximately along the middle third of the subject road. The slope varies in height from about 5 feet or less to about 15 feet, with the height increasing generally toward the north. In general, the slope is steep with an approximate inclination of 1:l(H:V) for most of its length. Four borings, B-1, and B-3 through B-5, as well as hand auger hole-2 were drilled at the top and 3 hand auger holes 7 - - - - - - r--- El Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 were drilled at the side and toe of the slope. The borings showed that the slope material is fill that consists primarily of loose to medium dense silty sand down to the alluvium. The fill thickness varies from about 10 feet at B-4 to about 15 feet at B-1. The heavy and above normal rainfall during the 2004/2005 winter season had a negative impact on the slope which included surface erosion and tracks of shallow water rivulets at various locations along the top and side surfaces of the slope. 8. DESIGN RECOMMENDATIONS 8.1. General Based on the results of the field explorations and engineering analyses, it is TE-USL's opinion that the proposed construction is feasible from a geotechnical standpoint, provided that the recommendations in this report are incorporated into the design plans and implemented during construction. Recommendations for the geoteclmical design and construction of the subject road improvements are presented below. 8.2. Site Preparation Clearing and Grubbing Prior to grading, the project area should be cleared of any existing structures, surface vegetation, rubble, trash, debris, etc. Any buried organic debris or other unsuitable contaminated material encountered during subsequent excavation and grading work should also be removed. Excavations made for removal of any existing footings, utility lines, tanks, and any other subterranean structures, laying within any proposed road alignment, should be processed and backfilled in the following mam1er: 1. Clear the excavation bottom and side cuts of all loose and/or disturbed material. 2. Prior to placing backfill, the excavation bottom should be moisture conditioned to within 2 percent of the optimum moisture content and compacted to at least 90 percent of the ASTM D-1557 laboratory test standard. 3. Backfill should be placed, moisture conditioned (i.e., watered and/or aerated as required and thoroughly mixed to a uniform, near optimum moisture content), and compacted by mechanical means in approximate 6-inch lifts. The degree of compaction obtained should be at least 90% of the ASTM D-1557 laboratory test standard. 8 ' ' i l. El Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 It is also critical that any surficial subgrade materials disturbed during initial demolition and clearing work be removed and/or recompacted in the course of subsequent site preparation earthwork operations. Site Grading In view of the non-unifonn characteristics of alluvial deposits and in order to create a uniform and firm bearing support for the proposed development, the following earthwork operations are recommended. • New Pavement/Concrete Sidewalks: Over-excavate the existing soils to a depth of at least 1.0 feet below existing ground surface or design subgrade, whichever is deeper, and to a lateral distance of at least 2 feet beyond the road embankment footprint or a'l constrained by existing features (e.g., utilities, walkways, etc.). • Light Standards: Over-excavate the existing soils to a depth of at least 2 feet below base of footing, and to a lateral distance of at least 2 feet beyond lateral extents of the footings or as constrained by existing adjacent features. All bottoms of over-excavations should be scarified a minimum of 8 inches, moisture conditioned to within 2 percent of the optimun1 moisture content, and compacted to at least - 90 percent of the maximum dry density per ASTM D-1557 test method. The bottom of over-- excavations should be inspected and tested by a representative of TE-USL prior to the placement of any compacted fill materials. Fill placement associated with the removal and re-compaction of any existing artificial fill and upper alluvium soils, utility trench backfill, and fill placed to achieve finish grade or subgrade elevations, should be moisture-conditioned to within 2 percent of the optimum moisture content. The fill should be compacted to at least 90 percent of the maximum dry density (note: at least 95 percent for the upper 12 inches in pavement areas), as evaluated by the latest version of ASTM D1557. In addition, two sack slurry back fill or as deemed appropriate by the utility owner should comprise the top foot of compacted fill to achieve finish grade in utility trenches. Import soils should be sampled, tested, and approved by TE-USL prior to arrival on site. Imported fill materials should consist of granular soils free from vegetation, debris, or rocks larger than 3 inches maximum dimension "'~th an Expansion Index of20 or less. 8.3. Temporary Excavations Excavation of the on-site soils may be achieved with conventional heavy-duty grading equipment. Temporary, unsw-charged, excavation walls may be back sloped at an inclination of l:l(H:V) in existing undocumented fill or alluvium. Personnel from TE-USL should observe any temporary excavations so that any necessary modifications based on variations in the encountered soil conditions can be made. All applicable safety requirements and regulations, including CalOSHA requirements, should be met. 9 - - - ! • El Camino Real Road Widening ContractNo.: 103582 March 28, 2006 Revised May 31, 2006 Where sloped excavations are used, the tops of the slopes should be barricaded so that vehicles and storage loads are not within 10 feet of the tops of excavated slopes. A greater setback may be necessary when considering heavy vehicles, such as concrete trucks and cranes. TE-USL should be advised of such heavy loadings so that specific setback requirements may be established. If the temporary construction slopes are to be maintained dw-ing the rainy season, berms are recommended along the tops of the slopes, to prevent runoff water from entering the excavation and eroding the slope faces. Vertical excavations greater than 4 feet high should not be attempted without proper shoring to prevent local instabilities. Shoring may be accomplished with hydraulic shores and trench plates, trench boxes, and/or soldier piles and lagging. The actual method of a shoring system should be provided and designed by a contractor experienced in installing temporary shoring under similar soil conditions. All trench excavations should be shored in accordance with CalOSHA regulations. 8.4. Utility Trench Excavations Temporary, shallow excavations with vertical side slopes less than 4 feet high may be stable, although localized sloughing should be anticipated. Vertical excavations greater than 4 feet high should not be attempted without proper shoring to prevent local instabilities. Shoring may be accomplished with hydraulic shores and trench plates, trench boxes, and/or soldier piles and lagging. The actual method of a shoring system should be provided and designed by a contractor experienced in installing temporary shoring under similar soil conditions. All trench excavations should be shored in accordance with CalOSHA regulations. For planning purposes, on-site fill and shallow alluvial deposits may be considered a Type B soil, as defined the current CalOSHA soil classification. For design of temporary shoring, a triangular distribution of lateral earth pressure may be used. It may be assumed that the retained soils with a level, unsurcharged, surface behind the shoring will exert a lateral pressure equal to that developed by a fluid with a density of 40 pollllds per cubic foot (pcf). Unless reflected in the shoring design, stockpiled (excavated) materials should be placed no closer to the edge of a trench excavation than a distance defined by a line drawn upward from the bottom of the trench at an inclination of 1:l(H:V), but no closer than 4 feet. All trench excavations should be made in accordance with CalOSHA requirements. 8.5. New Flexural Asphalt Concrete (AC) Pavement Laboratory testing of the near surface subgrade materials from test boring nos. 7, 8, and 10 yielded R-values of 13, 9, and 8, respectively. In any case an average R-value of 10 is recommended for the design of pavement sections. According to the City of Carlsbad Engineering Standards, Vol.I, General Design Standards, General Design Criteria, Table A, Street Design Criteria, the minimum traffic index, TI of a Prime Arterial is 9. And the minimum structural section is 6 inches AC over 18 inches AB for an R-value of 10 per the City of Carlsbad Supplemental Standard No. GS-17. The subject road is a prime arterial as IO L. ! 1 l_. i i l. I El Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 discussed in Section 4 of this report and hence the TI value of 9 should be used for pavement design. Based on these design parameters, analysis in accordance with the current Cal-Trans Highway Design Manual, and assuming compliance with site preparation recommendations, TE-USL recommends the following alternative pavement structural sections for the proposed road widening portion: 9.0 9.0 (I) (2) (3) (4) (5) Note: TABLE2 Asphalt Concrete Pavement Sections .. • 6.0 18.0 14.5 13.5 17.0(6)/15.0<7> Asphalt Concrete. . :Ar3'6J\ . .

The upper 12-inches ofsubgrade soils should be compacted to at least 95% relative compaction (ASTM D-1557). (6) AC Full Section (?) AC Full Section with Glassgrid mesh S502. It is recommended that R-value testing is performed on representative soil samples after rough grading operations on the upper 2 feet to confirm applicability of the above pavement sections. The aggregate base should confonn to the Crushed Aggregate Base per Greenbook requirements, Section 200-2.2. The base course should be compacted to a minimum dry density of 95% of the materials maximum density as determined by the ASTM 0-1557 test procedure. Field testing should be used to verify compaction, aggregate gradation, and compacted thickness. The asphalt concrete pavement should be compacted to 93% of the maximum theoretical unit weight as tested in accordance with the ASTM D-2041 procedure. The maximwn lift thickness should be two inches. The asphalt concrete material shall conform to Type III, Class C2 or C3, 2006 edition of the Greenbook Standard Specifications for Public Works Construction. An approved mix design should be submitted 30 days prior to placement. The mix design should include propo1tions of materials, maximum density and required lay-down 11 - - - - - • El Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 temperature range. Laboratory testing should be done to verify oil content, aggregate gradation, and maximum theoretical unit weight. Field testing should be used to test compaction, lift thickness, and lay-down temperature. If the paved areas are to be used during construction, the pavement section should be re- evaluated for the anticipated traffic. 8.6. Rubberized Asphalt Hot Mix Concrete (AC) Overlay Pavement Section 7 .1, Pavement Section, presented an average thickness of the existing pavement section equal to 10.2 inches comprised of 5.1 inch AC supported on 5.1 inch .AB. The existing pavement appears to be in good condition other than some distress signs-of fine alligator cracks primarily within the northern portion of the subject road. Rubberized asphalt concrete overlay is recommended to upgrade the pavement structural section corresponding to the design TI of 9 as reported in the preceding section and to mitigate these relatively minor distress areas. For a TI of 9 and a 20 year design period a 9 inch rubberized asphalt concrete pavement overlay is recommended. Nonetheless, the overlay thickness may be reduced to 7 inch with the installation of Glassgrid mesh 8502 or similar at the surface of the existing pavement prior to the application of the rubberized asphalt concrete overlay. However, and to minimize the immediate cost of overlay treatment a rehabilitation period of 10 years may be adopted, contingent upon the City approval, as a minimum life cycle of the overlay pavement section. If this approach is acceptable then a reduced thickness rubberized asphalt concrete overlay pavement may be designed to provide the required improvement. Based on Table 602.4A of the current Cal-Trans Highway Design Manual, the ESAL value corresponding to a TI of 9 ranges from 798,000 to 1,270,000 for a 20 year design period. If the ESAL value of 798,000 is chosen, then the ESAL value for a period of 10 years is 199,000 which correspond to a TI equal to 7. Accordingly, the minimum required thickness of the rubberized asphalt concrete pavement overlay is 4.0 inches. However, if Glassgrid mesh 8502 or similar is installed at the surface of the existing pavement prior to the application of the rubberized asphalt concrete overlay then the required overlay thickness may be reduced to 2.0 inches with an improved reduction of reflective cracking in the overlay pavement. On the same token, a 15 year design period will require a minimum rubberized asphalt concrete pavement overlay thickness of 4.0 inches with Glassgrid mesh 8502 or similar, or 6.0 inches without. However, if the ESAL value of 1,000,000 for a 20 year design period as computed according to the equation presented in the current Cal-Trans Highway Design Manual is chosen then the required rubberized asphalt concrete overlay thickness is 4 inches with Glassgrid mesh 8502 and 6 inches without, for a minimum life cycle period of 10 years . 12 i l El Camino Real Road Widening 8.7. Slope Construction Earth Fill Road Embankment Contract No.: I 03582 March 28, 2006 Revised May 31, 2006 As discussed in Section 7.2. the eastern side of the subject road earth fill embankment had suffered various levels of distress including sloughing and slope failure at the locations depicted on Figure 2, Plot Plan. The maximum height of the slope in these locations is about 15 feet. Figure No. 3 shows the factor of safety of the slope after the abnormally heavy rainfall season of the year 2004/2005. Surficial slope stability analysis indicated that the subject slope has a factor of safety less than I, signifying failure, which is the case as observed and reported earlier. To mitigate this failure as well as the sloughed area shown on Figure 2, Plot Plan, and maintain the pre-failure slope inclination, both slopes should be over- excavated and reconstructed as detailed in Figure 4, Fill Slope Detail. The fill should be compacted as described in Section 8.2. Slope stability analysis of mitigated 15 foot maximum height. slope produced a minimum factor of safety of 1.6, Figure 4, Fill Slope Detail. Higher values of the factor of safety are anticipated for similarly mitigated fill slopes less than 15 feet in height. The on-site soils, except alluvial clays or any contaminated soil, debris, organic matter, or other deleterious materials, may be used for backfill in the upper backfill zone. Any rock or - other soil fragments greater than 3 inches in size should not be used in fiJls. All imported fill, A if any, should consist of granular, non-expansive soil with an Expansion Index of 20 or less. W Import material should be evaluated by ow-firm prior to transport to the site and not contain any contaminated soil, expansive soil, debris, organic matter, or other deleterious materials. Western Existing Slopes The existing slopes along the west edge portion of El Camino Real Road approximately between Station 79+50 and Station 93+00 increases from about 1.5: 1 (H:V) at Station 79+50 to about 1:1 (H:V) at Station 84+00 throughout Station 87+00 then decreases more or less gradually to about 2.7:1 (H:V) at Station 93+00. If up to 8 foot high vertical cuts are proposed for widening this portion of the road then a tie-back wall is recommended to provide lateral support for these steepened slopes. Soldier piles with tie-back anchors will allow top down slope cut providing lateral support during construction. Alternatively a heavy counterfort retaining wall or similar will provide the required lateral support. However, temporary shoring will be required during construction of the latter alternatives. The actual shoring design should be provided by a registered civil engineer in the State of California experienced in the design and construction of these structures. Soldier pile and tie-back design parameters are presented in Section 8.8. Eastern Existing Slopes The existing slopes along the northeast edge of El Camino Real Road approximately between Station 68+00 and Station 77+00 are mainly in formational material. A cut slope of 1.5: I (H: V) may be constructed in these fonnational materials. Pe1manent steeper cuts or cuts in loose soil pockets should be supported by adequately designed retaining walls. 13 - - I I --- El Camino Real Road Widening 8.8. Shoring Systems/Retaining Walls Design Parameters 8.8.1. Lateral Earth Pressure Parameters Contract No.: 103582 March 28, 2006 Revised May 3J, 2006 The recommended lateral ea11h pressures for retaining walls free to rotate, with level, 2:1 (H:V), and 1.5:1 (H:V) slope, are 40, 55, and 75 pounds per cubic foot (equivalent fluid pressure), respectively. For restrained walls, at-rest lateral equivalent fluid pressures are 60, 75, and 95 pounds per cubic foot. If additional surface surcharge pressures and point loads are present then this office should be contacted to provide the lateral magnitude and distribution resulting from surchai·ge loads. In addition to the above-mentioned lateral earth pressures the retaining walls should be designed to support a seismic lateral pressure. The actual magnitude of the seismic lateral-pressure \vill depend on the slope inclination and the type and height of the retaining wall. Our office should be contacted to provide the seismic earth lateral pressure when the wall type and height has been chosen. 350 pounds per cubic foot ultimate equivalent fluid passive pressure in level grotmd is recommended for design. The recommended earth pressure is calculated assuming that a drainage system will be installed behind the retaining walls, so that extemal water pressure will not develop. 8.8.2. Soldier Pile Design The soldier piles should be designed in accordance with the geotechnical parameters presented in the table below. Soldier piles should be spaced no fmther apart than 8 feet on center. Table 3 G eotec mca es1~n h ' ID . P arame ers or ee 0 1er I e t :t St 1 S Id. P"l The depth of embedment of an isolated soldier pile into formation materials can be calculated using ultimate lateral passive 350 pcf resistance (EFP) Maximum ultimate lateral passive resistance (EFP) 5,000 pcf Increase (multiplier) of the ultimate lateral passive resistance due to arching (This value is applicable for soldier piles that are spaced no 3.0 closer than 3 diameters.) The above ultimate passive soil resistances should be reduced by a FS = 1.5 Factor of Safety to obtain the actual design values. For temporary construction continuous treated timber lagging should be used between the soldier piles. If treated timber is used, the lagging may remain in place. However, 14 i ' l .... !-! ' \. El Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 reinforced concrete lagging may be used between the soldier piles in permanent retaining walls. To develop the full lateral resistance, provisions should be taken to assure firm contact between the soldier piles and the formational materials. The concrete placed in the soldier pile excavations may be a lean-mix concrete. However, the concrete used in that portion of the soldier pile that is below the planned excavated level should provide sufficient strength to adequately transfer the imposed loads to the surrounding materials. Drilling of the pile shafts should be accomplished using heavy-duty excavation equipment. Although not anticipated, if water seepage is encountered during installation of shafts, dewatering and tremie seals may be necessary. 8.8.3. Tie-back. Anchor Design Tie-back friction anchors may be used to resist lateral loads. For design purposes, it may be assumed that the failure wedge adjacent to the shoring is defined by a plane drawn at 30 degrees from the vertical from the toe of the wall. The anchors should extend at least 20 feet beyond the potential failure wedge; this provision is to provide global stability for the shored wall. The bonded length should commence at least 5 feet beyond the failure wedge. · - Conventional drilled anchors (gravity grouted) may be designed for an allowable bond - stress of 1,500 psf. Pressure-grouted anchors may be designed for an allowable bond stress of 4,000 psf. Only the resistance developed within the bonded length should be used in resisting lateral loads. If the anchors are spaced at least 6 feet on center, no reduction in the capacity of the anchors need be considered due to group action. In no event should the anchors extend less than the minimum length beyond the potential failure wedge as given above. If the tie-back anchor system is intended for temporary use, provisions should be made in the design to de-tension and abandon the tie-backs when the retaining walls are able to support the lateral loads (note: consideration should be given to the utilization of fiberglass tendons where future excavations may occur). 8.8.4. Anchor Installation The anchors may be instal]ed at angles of 15 to 30 degrees below the horizontal. Difficult drilling conditions during installation of the anchors may occur within dense formational materials. In addition, localized caving may occur within uncemented formational materials. The anchors should be filled with concrete placed by pumping from the tip out and the concrete should extend from the tip of the anchor to the failure wedge. The portion of the anchor tendons outside of the bonded length should be sleeved in plastic. If the anchor tendons are sleeved, it is acceptable to grout the entire length of the anchor. 1.5 - - • - ' ,- i El Camino Real Road Widening 8.8.5. Anchor Testing .•. ,Q;, Contract No.: 103582 March 28, 2006 Revised May 3 1, 2006 All of the production anchors should be tested to at least 150% of the design load; the total deflection during the tests should not exceed 4 inches. The rate of creep under the 150% test should not exceed 0.1 inch over a 15-rninute period for the anchor to be approved for the design loading. After a satisfactory test, each production anchor should be locked-off at the design load. The locked-off load should be verified by rechecking the load in the anchor. If the locked-off load varies by more than 10% from the design load, the load should be reset until the anchor is locked-off within 10% of the design load. To reduce chances of caving during tie-back testing, the portion of the anchor shafts within the failure wedge may need to be backfilled with sand before testing the anchor. This p01tion of the shaft should be filled tightly and flush with the face of the excavation. The sand backfill may contain a small amount of cement to allow the sand to be placed by pumping. 8.8.6. Monitoring ' Monitoring the perfonnance of the shoring system and/or tie-back walls is considered necessary adjacent to El Camino Real Road and existing structural areas. Monitoring should consist of periodic surveying of lateral and vertical locations at the tops of selected soldier piles or proximate bench marks on existing buildings. The actual monitoring program should be developed jointly with the design consultants and the contractor when the design of the shoring system or tie-back retaining wall has been finalized. Deflections of the shoring or tie-back wall supporting cut slopes should not exceed one-inch. Movements in excess of one inch may occur as a result of construction- related disturbances or unforeseen site conditions. TE-USL should review the survey data as it relates to movements of the shoring, and provide recommendations for remedial measures, if necessary. 8.9. Foundations for Ancillary Structures A shallow foundation system may be used for support of relatively lightly loaded ancillary structures, such as site screen walls, light standards, etc. The foundations for each feature should be supported entirely on compacted fill prepared in accordance with the recommendations in Section 8.2. of this report. Recommendations for the design and construction of these shallow foundations are presented below. 8.9.1. Design Parameters Shallow foundations should be designed using the geotechnical design parameters presented in Table 4. Footings should be designed and reinforced in accordance with 16 El Camino Real Road Widening Contract No.: 103582 March 28, 2006 Revised May 31, 2006 the recommendations of the structural engineer and should conform to the 2001 California Building Code.

Pipe Bedding It is recommended that pipes be supported over 6 inches of¾" washed gravel. The gravel bed should be covered with filter fabric Mirafi 140N or approved equivalent. The edges of filter fabric should overlap a minimwn of 2 feet. Overlying the gravel on the sides and up to 1 foot above the pipe should be backfilled with ASTM C-33 concrete sand or approved granular soil with sand equivalent (SE) of 30 or greater. This pipe backfill material should be compacted in accordance with the recommendations in Section 8.2. of this report. 8.11. Sidewalk Concrete Slabs Side,;o.'alk concrete flatwork should have a minimum concrete thickness of four inches. All concrete should be supported on at least 4 inches of Class 2 aggregate base compacted to at least 95 percent of the maximum dry density. The upper 12 inches of subgrade soil located below the aggregate base should reconditioned to achieve a moisture content of within 2% of optimum moisture content, and compacted to 90 percent relative compaction (D-1557). Where driveways occur, the concrete aggregate base sections should be increased to 6 inches. For sidewalk concrete flatwork, we recommended that narrow strip concrete slabs, be reinforced with at least No. 3 reinforcing bars placed longitudinally at 36 inches on-center. Wide sidewalk slabs should be reinforced with at least No. 3 reinforcing bars placed 36 inches on-center, each way. The reinforcement should be extended through the control joints to reduce the potential for differential movement. Control joints should be constructed in accordance with recommendations of the civil or structural engineer. DESIGN REVIEW AND CONSTRUCTION MONITORING Geotcchnical review of plans and specifications is of paramount importance in engineering practice. The poor performance of many structures has been attributed to inadequate geotechnical revie,v of construction documents. Additionally, observation and testing of the subgrade \Vill be important to the performance of the proposed improvements. The following sections present our recommendations relative to the review of construction documents and the monitoring of construction activities. 9.1. Plans and Specifications The design plans and specifications should be reviewed and approved by TE-USL prior to bidding and construction, as the geotechnical recommendations may need to be reevaluated in the light of the actual design configuration. This review is necessary to evaluate whether the recommendations contained in this report and future reports have been properly incorporated into the project plans and specifications. Based on the work already performed, this office is best qualified to provide such review. 18 El Camino Real Road Widening 9.2. Construction Monitoring Contract No.: 103582 March 28, 2006 Revised May 31, 2006 Site preparation, removal of unsuitable soils, assessment of imported fill materials, fill placement, and other earthwork operations should be observed and tested. The substrata exposed during the construction may differ from that encountered in the test borings. Continuous observation by a representative of TE-USL during construction allows for evaluation of the soil conditions as they are encountered, and allows the opportunity to recommend appropriate revisions where necessary. 10. LIMITATIONS The recommendations and opinions expressed in this report are based on TE-USL's review of background documents and on information obtained from field explorations. It should fie noted that this study did not evaluate the possible presence of hazardous materials on any portion of the site. Due to the limited nature of our field explorations, conditions not observed and described in this report may be present on the site. Uncertainties relative to subsurface conditions can be reduced through additional subsurface exploration. Additional subsurface evaluation and laboratory testing can he performed upon request. It should be understood that conditions different from those anticipated in this report may be encountered during construction, e.g., the extent of removal of unsuitable soil, and that additional effort may be required to mitigate them. Site conditions, including groundwater elevation, can change with time as a result of natural processes or the activities of man at the subject site or at nearby sites. Changes to the applicable laws, regulations, codes, and standards of practice may occur as a result of government action or the broadening of knowledge. The findings of this report may, therefore, be invalidated over time, in part or in whole, by changes over which TESD has no control. TE-lJSL's recommendations for this site are, to a high degree, dependent upon appropriate quality control of subgrade preparation, fill placement, etc. Accordingly, the recommendations are made contingent upon the opportunity for TE-USL to observe the earthwork operations for the proposed construction. If parties other than TESD are engaged to provide such services, such parties must be notified that they will be required to assume complete responsibility as the geotechnical engineer of record for the geotechnical phase of the project by concurring with the recommendations in this report and/or by providing alternative recommendations. This document is intended to be used only in its entirety. No portion of the document, by itself, is designed to completely represent any aspect of the project described herein. TE-USL should be contacted if the reader requires additional information or has questions regarding the content, interpretations presented, or completeness of this document. - - TE-USL has endeavored to perform our evaluation using the degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical professionals with experience in - this area in similar soil conditions. No other warranty, either expressed or implied, is made as to the conclusions and recommendations contained in this report. 19 -El Camino Real Road Widening 11.

Geotechnical Services Are Performed for Specific Purposes, Persons, and Projects Geotechnical engineers structure their services to meet the specific needs of their clients. A geotechnical engineering study conducted for a civil engi- neer may not fulfill the needs of a construction contractor or even another civil engineer. Because each geotechnical engineering study is unique, each geotechnical engineering report is unique, prepared solelyfor the client. No , one except you should rely on your geotechnical engineering report without first conferring with the geotechnical engineer who prepared it. And no one --not even you -should apply the report for any purpose or project except the one originally contemplated. Read the f1dl Report Serious problems have occurred because those relying on a geotechnical engineering report did not read it all. Do not rely on an executive summary. Do not read selected elements only. : =-~:i~~:s-00 Geotechnical engineers consider a number of unique, project-specific fac- tors when establishing the scope of a study. Typical factors include: the client's goals, objectives, and risk management preferences; the general nature of the structure involved, its size, and configuration; the location of the structure on the site: and other planned or existing site improvements, such as access roads, parking lots, and underground utilities. Unless the geotechnical engineer who conducted the study specifically indicates oth- erwise, do not rely on a geotechnical engineering report that was " not prepared for you, • not prepared for your project, " not prepared for the specific site explored, or • completed before important project changes were made. Typical changes that can erode the reliability of an existing geotechnical engineering report include those that affect: • the function of the proposed structure, as when it's changed from a parking garage to an office building, or from a light industrial plant to a refrigerated warehouse, -• elevation, configuration, location, orientation, or weight of the proposed structure, • composition of the design team, or • project ownership. As a general rule, always inform your geotechnical engineer of project changes-even minor ones--and request an assessment of their impact. Geotechnical engineers cannot accept responsibility or liability tor problems that occur because their reports do not consider developments of which they were not informed. Sollsurface C8ndl1itms Can Change A geotechnical engineering report is based on conditions that existed at the time the study was performed. Do not rely on a geotechnical engineer- ing report whose adequacy may have been affected by: the passage of time; by man-made events, such as construction on or adjacent to the site: or by natural events, such as floods, earthquakes. or groundwater fluctua- tions. Always contact the geotechnical engineer before applying the report to determine if it is still reliable. A minor amount of additional testing or analysis could prevent major problems. Mest Geotechnical FiH1R1S Are Prolesll8ul Opiniens Site exploration identifies subsurface conditions only at t110se points where subsurface tests are conducted or samples are taken. Geotechnical engi- neers review field and laboratory data and then apply their professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ-sometimes significantly- from those indicated in your report. Retaining the geotechnical engineer who developed your report to provide construction observation is the most ettective method of managing the risks associated with unanticipated conditions. A Report's Recommendations Are Not Final Do not overrely on the construction recommendations included in your report. Those recommendations are not final, because geotechnical engi- neers develop them principally from judgment and opinion. Geotechnical engineers can finalize their recommendations only by observing actual ,;ubsurtace conditions revealed during construction. The geotechnical ·engineer who developed your report cannot assume responsibility or liability tor the report's recommendations if that engineer does not perform construction observation. A Geoteclmical Engineering Report Is Subject to Misinterpretation Other design team members' misinterpretation of geotechnical engineering reports has resulted in costly problems. Lower that risk by having your geo- technical engineer confer with appropriate members of the design team after submitting the report. Also retain your geotechnical engineer to review perti- nent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering report. Reduce that risk by having your geotechnical engineer participate in prebid and preconstruction conferences, and by providing construction observation. Do Not Redraw the Engineer1s Logs Geotechnical engineers prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical engineering report should f1ever be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk. Give Contractors a co•te Report and Guidance Some owners and design professionals mistakenly believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give con- tractors the complete geotechnical engineering report, but preface it wit~1 a clearly written letter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and 1hat the report's accuracy is limited; encourage them to confer with the geotechnical engineer who prepared the report (a modest fee may be required) and/or to conduct additional study to obtain the specific types of information they need or prefer. A prebid conference can also be valuable. Be sure contrac- tors have sufficient time to perform additional study. Only then might you be in a position to give contractors the best information available to you, while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions. Read Responslility Provisions Closely Some clients, design professionals, and contractors do not recognize that geotechnical engineering is far less exact than other engineering disci- plines. This lack of understanding has created unrealistic expectations that have led to disappointments, claims, and disputes. To help reduce the risk of such outcomes, geotechnical engineers commonly include a variety of explanatory provisions in their reports. Sometimes labeled "limitations" many of these provisions indicate where geotechnical engineers' responsi- bilities begin and end, lo help others recognize their own responsibilities and risks. Read these provisions closely. Ask questions. Your geotechnical engineer should respond fully and frankly. Geoenvironmental Concerns Are Not Covered The equipment, techniques, and personnel used to perform a geoenviron- men!a/ study differ significantly from those used to perform a geotechf1ica/ study. For that reason, a geotechnical engineering report does not usually relate any geoenvironmental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated environmental problems have led to numerous project failures. If you have not yet obtained your own geoen- vironmenlal information, ask your geotechnical consultant for risk man- agement guidance. Do not rely on an environmental report prepar&d for -- someone else. Obtain Professional Assistance To Deal with Mold Diverse strategies can be applied during building design, construction, operation, and maintenance to prevent significant amounts of mold from growing on indoor surfaces. To be effective, all such strategies should be devised for the express purpose of mold prevention, integrated into a com- prehensive plan, and executed with diligent oversight by a professional mold prevention consultant. Because just a small amount of water or moisture can lead to the development of severe mold infestations, a num- ber of mold prevention strategies focus on keeping building surfaces dry. While groundwater, water infiltration, and similar issues may have been addressed as part of the geotechnical engineering study whose findings are conveyed in this report, the geotechnical engineer in charge of this project is not a mold prevention consultant; none of the services per- formed in connection with the geotechnical engineer's study were designed or conducted tor the purpose of mold preven- tion. Proper implementation of the recommendations conveyed in this report wi!! not of itself be sufficient to prevent mold from growing in or on the structure involved.

INTRODUCTION October 15, 2009 Project No. 106641001 In accordance with your request and our proposal dated April 12, 2009, we have performed a geo- technical evaluation for the proposed Retaining Walls A and B, which will be constructed as part of the El Camino Real widening project located in Carlsbad, California (Figure 1 ). The purpose of this study was to evaluate the subsurface conditions at the project site and to provide design rec- ommendations for the construction of the proposed retaining walls. This report presents our fmdings, conclusions, and recommendations regarding the subject project. 2. SCOPE OF SERVICES Ninyo & Moore's scope of services for this project included review of pertinent background data, performance of a geologic reconnaissance and subsurface evaluation, and engineering analysis with regard to the proposed project. Specifically, we performed the following tasks: • Reviewing background data listed in the References section of this report. The data reviewed included geotechnical literature, topographic maps, geologic data, fault maps, and a site plan -for the project. - • Performing a geologic reconnaissance of the proposed retaining wall sites including the ob- servation and mapping of geologic conditions and the evaluation of possible geologic hazards which may impact the proposed project. • Marking proposed boring locations prior to contacting Underground Service Alert (USA) for underground utility clearance at the project site. • Performing a subsurface evaluation consisting of drilling six small diameter borings to evaluate the subsurface conditions. • Performing geotechnical laboratory testing on selected soil samples to evaluate design parameters. • Compiling and analyzing the data obtained from our background research, subsurface evaluation, and laboratory testing. • Preparing this report presenting our findings, conclusions, and recommendations regarding the geotechnical design and construction of the project. 106641001 R.dO<: El Camino Real Widening, Retaining Walls A and B Carlsbad, California 3. SITE AND PROJECT DESCRIPTION October 15, 2009 Project No. 106641001 The proposed Retaining Walls A and B project is located along the west side of El Camino Real at approximate Stations 513+70 to 526+40 between Tamarack and Chestnut Avenues in Carls- bad, California. The project area consists of a four-lane asphalt paved street bordered by ascending slopes to the west. The site is developed with paved curbs and gutters along the west side of the street. Several underground utility lines were observed within the project area includ- ing storm drains crossing the proposed retaining wall alignment. Overhead electrical lines and communication lines were also observed along the east side of El Camino Real in a residential area Elevations along El Camino Real at the project site range from a low of approximately 156 feet above mean sea level (MSL) to a high of a11proximately 216 feet MSL at the northern end of the site. Vegetation on the slopes adjacent to the proposed retaining wall generally consists of a moderate growth of grass, weeds, brush, and trees. Based on our review of the retaining wall plan and profile provided to us by Simon Wong Engi- neering (2009), it is our understanding that the proposed soldier pile retaining walls with sculpted shofcrete over timber lagging will be constructed in two segments. Retaining wall '.N will be approximately 338 feet long and retaining wall 'B' will be approximately 896 feet long, with heights of 10 and 14 feet, respectively. Natural slopes above the proposed retaining wall vary in gradient from approximately 2: 1 to 1: 1. 4. SUBSURFACE EVALUATION AND LABORATORY TESTING Our subsurface evaluation was conducted on August 20 and 21, 2009 and consisted of drilling six small diameter borings with a truck mmmted drill rig to depths of up to approximately 41.5 feet. The boring locations were selected based on the results of our background review, field reconnaissance, the anticipated construction at the site, and locations of existing utilities. Prior to commencing the subsurface evaluation, USA vvas notified for mark-out of the existing utilities. The approximate locations of the borings are presented on Figures 2A and 2B. The boring logs are presented in Appendix A. 106641001 R.doc 2 - • - El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 Laboratory testing of representative soil samples included an evaluation of in-place moisture and density, shear strength, and soil corrosivity. The results of the laboratory tests performed are pre- sented in Appendix B. 5. GEOLOGY AND SUBSURFACE CONDITIONS Our findings regarding regional and site geology and groundwater conditions at the subject site are provided in the following sections. 5.1. Regional and Geologic Setting The project area is situated in the San Diego County coastal section of the Peninsular Ranges Geomorphic Province. This geomorphic province encompasses an area that extends approximately 900 miles from the Transverse Ranges and the Los Angeles Basin south to the southern tip of Baja California (Norris and Webb, 1990). The province varies in width from approximately 30 to 100 miles. In general, the province consists of rugged mountains underlain by Jurassic metavolcanic and metasedimentary rocks, and Cretaceous igneous rocks of the southern California batholith. The portion of the province in San Diego County that includes the project area consists generally of Tertiary sedimentary rock. 5.2. Site Geology Geologic units encountered during our reconnaissance and subsurface evaluation included fill, alluvium, and materials of the Santiago Formation. Generalized descriptions of the units encountered are provided in the subsequent sections. More detailed descriptions are pro- vided on the boring logs in Appendix A. 5.2.1. Fill Fill was encountered in borings B-1 through B-6 from beneath the existing pavement section to depths of approximately 2 to 3 feet. As observed and encountered, the materi- als generally consisted of brown, damp to moist, medium dense, silty fme to coarse sand. Fill materials are not expected to be encountered at the retaining wall locations. 106641001 RdOG 3 El Camino Real Widening, Retaining Walls A an.d B Carlsbad, California 5.2.2. Alluvium October 15, 2009 Project No. 106641001 Alluvium is present along portions of the site and was encountered in beneath the roadway in borings B-1, B-2, and B-6 from beneath the fill to depths of approxi- mately 21, 35, and 9 feet, respectively. As encountered, the materials generally consisted of various shades of brown and reddish brown, moist to wet, medium dense to dense, clayey, silty, or poorly graded sand and very stiff sandy clay. 5.2.3. Santiago Formation Materials of the Santiago Formation were encountered in borings B-1, B-3, B-4, B-5, and B-6 ·underlying the fill and/or alluvium to the depths explored. As encountered, the materials generally consisted of light 1to dark shades of olive gray, brown, and white, damp to moist, weakly to moderately cemented, clayey, silty, fine to coarse-grained sandstone interbedded with moderately indurated, sandy and clayey siltstone and sandy claystone. Boring B-4 met shallow drilling refusal at approximately 20 feet due to the cemented nature of the underlying mat,erials. Materials of the Santiago Formation were observed in the existing cut slope and as outcrops along El Camino Real adjacent to borings B-3, B-4, and B-5. 5.3. Groundwater Groundwater was not encountered in our borings during the time of our exploration. Based on our background review of the site, groundwater is estimated to be located at a depth in excess of 20 feet below the ground surface. Fluctuations in the groundwater level may occur due to variations in ground surface topography, subsurface geologic conditions and struc- ture, rainfall, irrigation, and other factors. However, seepage, particularly at geologic . contacts, should be anticipated based on site geology and topography. 1<1664100 I R.doc 4 - - - - El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 6. GEOLOGIC HAZARDS In general, hazards associated with seismic activity include ground surface rupture, strong ground motion, tsunamis, and liquefaction. These considerations and othe:r:: geologic hazards such ,, .i as landsliding are discussed in the following sections. .:..:~ ... 6.1. Faulting and Seismicity The project area is considered to be seismically active. Based on our review of the refer- enced geologic maps and stereoscopic aerial photographs, as well as our geologic field reconnaissance, the subject site is not underlain by known active or potentially active faults (i.e., faults that exhibit evidence of ground displacement in the last 11,000 years and 2,000,000 years, respectively). Major known active faults in the region consist generally of en-echelon, northwest-striking, right-lateral, strike-slip faults. These include the San Clemente, Agua Blanca-Coronado Banlc, Newport-Inglewood, and Rose Canyon faults, lo- cated to the west of the site, and the Whittier-Elsinore, San Jacinto, and San Andreas faults, located to the east of the site. The locations of these faults are shown on Figure 3. The nearest known active fault is the Rose Canyon fault system, located approximately 6 miles..west of the site, which can generate an earthquake magnitude of up to 7.2 (Cao, etal., 2003)._ 6.1.1. Strong Ground Motion The 2007 California Building Code (CBC) recommends that the design of structures be based on the peak horizontal ground acceleration having a 2 percent probability of ex- ceedance in 50 years, which is defined as the Maximum Considered Earthquake (MCE). The statistical return period for PGAMcE is approximately 2,475 years. The Design Earthquake (PGAnE) corresponds to two-thirds of the PGAMcE, and this value is typi- cally used for residential and commercial structures. Based on our review of subsurface data, the project site corresponds to a Site Class C. The site modified PGAMcE and PGA08 were estimated to be 0.49g and 0.33g, respectively, using the United States Geo- logical Survey (USGS) (USGS, 2009) ground motion calculator (web-based). These ' 106641001 lldoc 5 El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 estimates of ground motion do not include near-source factors that may be applicable to the design of structures on site. 6.1.2. Ground Surface Rupture Based on our review of the referenced literature and our site reconnaissance, no active faults are known to cross the project site~. Therefore, the potential for ground rupture due to faulting at the site is unlikely. However, lurching or cracking of the ground surface as a result of nearby seismic events is possible. 6.1.3. Liquefaction and Seismically Induced Settlement Liquefaction of cohesionless soils can be caused by strong vibratory motion due to earth- quakes. Research and historical data indicate that loose granular soils and non-plastic silts that are saturated by a relatively shallow groundwater table are susceptible to liquefaction. Based on the dense nature of the formational materials underlying the site and the esti- mated depth to groundwater, the potential for liquefaction is not a design consideration. 6.2. Landsliding Based on our review of published geologic literature and aerial photographs, and our geo- logic reconnaissance, landslides or related features have not been recognized as underlying the project site. 7. CONCLUSIONS Based on our review of the referenced background data, geologic field reconnaissance, and sub- surface exploration, it is our opinion that construction of the proposed project is feasible from a geotechnical standpoint. Geotechnical considerations include the following: • The proposed retaining wall will be installe:d in Santiago Formation materials consisting of claystone, siltstone, and sandstone. Although not anticipated, alluvium may be encountered during drilling. 106641001 R.doc 6 - - El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 • The proposed earthwork should be feasible with earthmoving equipment in good working or- der. However, strongly cemented zones within materials of the Santiago Formation may be encountered which would entail the use of heavy ripping, rock breakers, or core barrels. • Although groundwater was not encountered during drilling, seepage, particularly at geologic contacts, should be anticipated based on site geology and topography. • Except where select backfill is recommended, on site materials are generally considered suitable for reuse as engineered fill provided that they are processed and prepared in accor- dance with the following recommendations. • Our analysis indicates that the factor of safety against surficial instability is marginal (not more than 1.5) for a slope inclination of 1: 1 (horizontal to vertical). Therefore, maintenance of the slope above the wall should be anticipated as the proposed wall system will not ad- dress surficial slope stability. • The site is subject to strong ground motion in the event of a nearby major earthquake. • Earthquake induced liquefaction is not considered a design consideration due to the density and consistency of soils encountered during our subsurface exploration and the depth to the historic high groundwater table. -• Toe potential for an earthquake induced landslide is considered low. - 8. RECOMMENDATIONS Based on the results of our subsurface evaluation and our understanding of the proposed con- struction, we present the following geotechnical recommendations relative to the design and construction of the proposed retaining walls. The proposed construction should also be per- formed in accordance with the requirements of applicable governing agencies. 8.1. Earthwork Based on our understanding of the project, earthwork is anticipated to consist of excavating earth materials as the soldier pile walls will be constructed utilizing a ''top down" approach. Earthwork should be performed in accordance with the requirements of applicable govern- ing agencies and the recommendations presented in this report. 106641001 R.doc . 7 El Camino Real Widening, Retaining Walls A an.d B Carlsbad, California 8.1.1. Site Preparation October 15, 2009 Project No. 106641001 Prior to excavation, the project site should be cleared of surface obstructions, existing pavement sections, and stripped of rubble, debris, vegetation, any loose, wet, or other- wise unstable soils, as well as surface soils containing organic material. Existing utilities within the project limits should. be abandoned, rerouted, or protected from dam- age by construction activities. Obstructions that extend below finish grade, if any, should be removed and the resulting holes filled with compacted soils. Materials gener- ated from the clearing operations shoulld be removed from the site and disposed of at a legal dumpsite away from the project area. As indicated in the preliminary plans, the proposed soldier pile walls will be constructed against existing cut slopes with inclinations ranging from 0.66:1 to 2:1. Based on the weathered nature of shallow formational materials, we anticipate that :further excavation may be recommended during construction beyond the scheduled cut for the soldier pile and lagging wall. The geotechnical rc,presentative should evaluate the cut materials should potentially expansive or othervli.se unsuitable soil be encountered behind the planned retaining wall. 8.1.2. Excavation Characteristics We anticipate that excavation of the site materials can generally be accomplished with heavy construction equipment in good operating condition. Strongly cemented zones within the Santiago Formation (concretions) may be encountered at the site and will be difficult to rip or drill through. The use of heavy ripping and/or rock breaking equip- ment or core barrels should be anticipated. 8.1.3. Materials for Fill On-site soils relatively free of organics are suitable for reuse as fill. Fill material should generally not contain rocks or lumps over approximately 3 inches, and generally not more than approximately 30 percent larger than 3/4 inch. Utility trench backfill material should not contain rocks or lumps over approximately 3 inches in general. Soils classi- J06641001 ll.doc - - - - - El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 fled as silts or clays should not be used for backfill behind retaining walls or in the util- ity pipe zone. Larger chunks, if generated during excavation, may be broken into acceptably sized pieces or disposed of off site. Imported fill material, if needed for the project, should generally be granular soils with a very low to low expansion potential (i.e., an EI of 50 or less as evaluated by the American Society for Testing and Materi- als [AS'IM] D 4829). Import material should also be non-corrosive in accordance with the Caltrans (2003) corrosion guidelines. Materials for use as fill should be evaluated by Ninyo & Moore's representative prior to filling or importing. A summary of these rec- ommendations are presented in the following table. Table 1 -Recommended Materials Material and Use Source Recommendation1,2 Select Fill Sand Equivalent of20 or more -for retaining wall backfill5 Import 100 percent passing 1-inch sieve 0 to 12 percent passing No. 200 sieve General Fill On-site borrow No additional requirements1 -for uses not otherwise specified Select Penneable Aggregate Import Class 2; CSS4 Section 68-1.025 -subdrain, soldier-pile-and-la2em2 wall Notes: 1 In genera], fill should be free of rocks or lumps in excess of 3 inches in diameter, trash, debris, roots, vegetation or other deleterious material. 2 · In general, import fill should be tested or documented to be non--corrosive3 and free from hazardous materials in concentrations above levels of concern. 3 Non-corrosive as defined by the Corrosion Guidelines version 1.0 (Caltrans, 2003). 4 CSS is California Standard Specifications (Caltrans. 2006) 5 Placed above a plane risina up and away from the bottom of the wall la2llin2 at a 1: 1 angle. 8.1.4. Compacted Fill Prior to placement of compacted fill, the contractor should request an evaluation of the exposed ground surface by Ninyo & Moore. Unless otherwise recommended, the exposed ground surface should then be scarified to a depth of approximately 8 inches and watered or dried, as needed, to achieve moisture contents generally above the optimum moisture content. The scarified materials should then be compacted to a relative compaction of 90 percent as evaluated in accordance with ASTM D 1557. The evaluation of compaction by the geotechnical consultant should not be considered to preclude any requirements for 106641001 R.doc 9 El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 observation or approval by governing agencies. It is the contractor's responsibility to no- tify the geotechnical consultant and the appropriate governing agency when the project area is ready for observation, and to provide reasonable time for that review . . Fill materials should be moisture conditioned to generally above the laboratory opti- mum moisture content prior to placement. The optimum moisture content will vary with material type and other factors. Moisture conditioning of fill soils should be generally consistent within the soil mass. Prior to placement of additional compacted fill material following a delay in the grading operations, the exposed surface of previously compacted fill should be prepared to receive fill. Preparation may include scarification, moisture conditioning, and recompaction. Compacted fill should be placed in h01izontal lifts of approximately 8 inches in loose thickness. Prior to compaction, each lift should be watered or dried as needed to achieve a moisture content generally above the laboratory optimum, mixed, and then compacted by mechanical methods, using sheepsfoot rollers, multiple-wheel pneumatic-tired rollers or other appropriate compacting rollers, to a relative compaction of 90 percent as evalu- ated by ASTM D 1557. Successive lifts should be treated in a like manner until the desired :finished grades are achieved. 8.1.5. Fill Slopes Should fill slopes be needed to accomplish the project, fill slopes should not be steeper than 2: 1, unless otherwise recommended by Ninyo & Moore and approved by the regulating agencies. Compaction of the face of fill slopes should be performed by backrolling at inter- vals of 4 feet or less in vertical slope height, or as dictated by the capability of the available equipment, whichever is less. Fill slope~ should be backrolled utilizing a conventional sheepsfoot-type roller. Care should be t:lken to maintain the desired moisture conditions and/or reestablish them, as needed, prior to backrolling. · l06641001 R.doc 10 - - - - - El Camino Real Widening, Retaining Walls A and B Carlsbad, California 8.1.6. Site Runoff October 15, 2009 Project No. 106641001 Site runoff should not be permitted to flow over the tops of slopes. Positive drainage should be established away from the top of slopes. This may be accomplished by utiliz- ing brow ditches placed at the top of slopes to divert surface runoff away from the slope face where drainage devices are not otherwise available. The on-site soils will be susceptible to erosion; therefore, the project plans and specifi- cations should contain design features and construction requirements to mitigate erosion of on-site soils during and after construction. Slopes and other exposed ground surfaces should be appropriately planted with protective ground cover. 8.2. Slope Stability Both surficial and global stability analyses were performed for the proposed retaining wall system. The intent of the surficial stability analysis was to evaluate the surficial erosion po- tential of the slope area behind the soldier pile wall. Our analysis indicates that the factor of safety against surficial instability is marginal (not more than 1.5) for a slope inclination of 1: 1 with a 4-foot zone of saturation beneath the slope face. Global stability analyses for the retaining wall system were performed using the surface and subsurface profile of geologic units based on the preliminary project plans and the results of our exploratory borings. Global stability analysis was performed on a representative section where the wall height is about 14 feet, and a soldier pile and lagging system would be utilized. The intent of the global stability analysis was to evaluate the potential for deep-seated, rota- tional failures (Simplified Janbu type) through Santiago Formation materials. The global stability analysis was also used as a tool to evaluate the need for tieback anchors and the lat- eral load bearing capacity of the soldier pile wall. A two-dimensional stability analysis program, GSTABL 7, was used for this purpose. The design factors of safety under static and pseudo-static loading conditions were 1.5 and 1.1, respectively, following accepted geotech- nical practices and agency guidelines. A horizontal acceleration coefficient of 0.15g was used to evaluate the pseudo-static stability. The bedrock layers were assigned homogeneous, 106641001 R.doc ll El Camino Real Widening, Retaining Walls A and B Carlsbad, California October l S, 2009 Project No. 10664100 l isotropic strength properties derived from laboratory direct shear tests performed during this evaluation. Ultimate and peak shear strength values were used for evaluating stability under static and pseudo-static loading conditions, respectively. Our global stability analyses indicate that th€~ proposed soldier-pile-and-lagging walls retain- ing slopes up to I: l inclination have adequate factors of safety under static and pseudo-static loading conditions provided the recommendations presented in the following sections are implemented into project design and construiction. 8.3. Retaining Walls Recommendations are presented in the following section for a soldier-pile-and-lagging wall to support the planned cut. Soldier pile:, and lagging walls are typically constructed in a top-down fashion and generally do not entail significant excavation behind the wall. As such, soldier pile and lagging walls are well-suited to support cut faces, particularly on slopes. We understand that buried vaults 1111ay also be constructed on the order of 8 feet deep as part of the project. 8.3.1. Soldier Pile and Lagging W alll Soldier pile and lagging walls may be used to retain soil adjacent to the proposed road widening. A soldier pile and lagging wall generally consists of wide-flange steel beams set into drilled concrete piers. Wood, stt:,el, or pre-cast concrete lagging supports the re- tained soil between the soldier piles. Wood lagging should be appropriately treated to reduce the potential for deterioration. Steel and concrete lagging should be specified with consideration for the corrosive or deleterious nature of the on-site soil materials (Section 8.1.3). Use of non-corrosive wall backfill material may reduce the potential for corrosion of steel members or sulfate attack on concrete. Recommendations for concrete cover over steel in the drilled piers are presented in our Concrete section. Soldier-pile-and-lagging walls may be designed for yielding conditions wherein the wall rotates away from the retained soil and the at-rest earth pressures are reduced to 106641001 R.doc 12 - - - - El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 active pressures. The movement of the top of the wall to develop active pressures should be about one tenth of one percent of the wall height for walls retaining formational materials, assuming weathered, expansive materials are generally removed. Soldier-pile-and-lagging walls should be designed for the active and passive earth pres- sures listed in Table 2. Where the engineer indicates that cut exposes expansive on-site soils, they should be removed from the zone of influence behind the wall and replaced with select fill to reduce the relatively high active lateral earth pressures characteristic of expansive soils. Active lateral earth pressures for anticipated cut materials and select import backfill are presented. Walls retaining flat ground are not anticipated, however, sloping ground above the cut is considered. The recommended pressures should be con- sidered ultimate values and do not include a factor of safety. !06641001 R.doc Table 2 -Soldier Pile Wall Design Parameters Active Seismic Passive Retained Assumed Backfill Equivalent Fluid Earth Equivalent Slope Material 111 Pressure Pressure Fluid (H:V) Ya (pct) [21[31 Ye (pcf)l4l Pressure v ...

The passive pressure should be neglected to a depth of one foot below the backfill surface when the backfill surface is not covered by a concrete slab or as- phalt pavement The passive resistance may be increased by one-third when considering loads of short duration such as wind or seismic forces. Once the depth of embedment and point of rotation are selected to meet static and mo- ment equilibrium at the tip (base) of the soldier pile, the depth of embedment should be increased by 20 to 40 percent for an approximate factor of safety of 1.5 to 2.0, respec- tively. Global stability of retaining walls is addressed previously. 13 l(ln90,$t JV\OOl"ll El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 Soldier piles may be designed for an idlowable side friction of 16L pounds per square foot to resist vertical loads where 'L' is the pile embedment length in feet. The soldier piles may be considered to have an effective width (with respect to earth pressures) of 3B, where 'B' is the diameter of the ,concrete pier, provided that the center-to-center spacing of the soldier piles is equivalent to 3B or wider. An effective pier width equiva- lent to the pier spacing may be assumed where the center-to-center spacing is less than 3B. On level ground, lagging should be continued to 1 foot below grade at the bottom of the wall. On sloping ground, the lagging should be continued to 1 foot below the point where there is 5 feet of lateral clearance between the wall and the slope face. Passive pressure should be neglected above the bottom of the lagging. The vertical distance from the bottom of the lagging to the grade of the retained soil should be used as the wall height for design purposes. Should granular backfill be used to fill gaps between the cut and the wall, measures should be taken to reduce potential for erosion and loss of the retained soil. Filter fabric (Mirafi 140NC or equivalent) should be placed against the backside of the cut to sepa- rate the granular backfill. To reduce discoloration and corrosion attack due to seepage through the wall facing, sealant may be placed between lagging members. Because the wall will receive a shotcrete texture, g,:ocomposite drain panels (Miradrain 6000XL, or similar) should be carefully installed as strip drains between the lagging members and the retained soil. The strip drain panels should be 2 feet wide or more and each panel outlet by weepholes if a slip hazard is not present at the toe of wall. If seepage at the toe of wall is not tolerable, the strip drain should extend below the lagging into a subdrain trench constructed in front of the wall, below the bottom elevation of the lagging. The subdrain trench should be backfilled with select permeable aggregate (Section 8.1.3) and capped with a pavement, concrete~ slab, or 1 foot of native soil. Perforated pipe (Schedule 40 PVC) should be placed °"ithin the subdrain trench and sloped at 1 percent or more towards a solid collector pipe (Schedule 40 PVC). Approximately 4 cubic feet of select permeable aggregate per linear foot should be placed around the perforated pipe. Crushed rock wrapped with filter fabric is not a suitable alternative to select per- 106541001 R.doc 14 - - - - - El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 10664100 I meable aggregate for this application. The collector pipe should be sloped at 2 percent or more to discharge at a suitable outlet away from the wall. Cleanouts should be pro- vided to facilitate periodic maintenance. The outfall from the collector pipe should be equipped with an energy dissipater and rodent screens. The geotechnical engineer should be provided an opportunity to observe subdrain construction, should it be the se- lected drainage method. Soldier piles should be installed close to the planned location. The soldier piles should not be out of plumb by more than 5 percent over the length of the pile. Furthermore, the top of the pile should be within 3 inches of the design location. Cast-in-drilled-hole sol- dier piles should be drilled to the specified depth, and the shaft bottom should be cleaned of loose material prior to pouring concrete. Excavations may not remain stable for a significant length of time. The contractor should be prepared to use temporary cas- ing or drilling fluid to inhibit the shaft excavation from collapsing. Standing water should be removed from the pier excavation or the concrete should be delivered to the bottom of the excavation, below the water surface, by tremie pipe. Casing, if used, should be removed from the excavation as the concrete is placed. Concrete should be placed in a manner that reduces the potential for segregation of the components. The drilled hole above the poured concrete may need to be backfilled with lean concrete to stabilize the hole while the excavation proceeds and lagging is installed. The geotechnical consultant should be permitted to observe the drilling and construction of the soldier piles to check that the embedment criteria are satisfied, the materials en- countered match the design assumptions, and that the appropriate construction procedures were followed. 8.3.2. Buried Vaults Should buried vaults be planned for the site as part of a storm drain system, the vault walls may be designed to resist an earth pressure from backfill equivalent to a fluid with 106641001 R.doc 15 El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 a unit weight of 60 pounds per cubic foot. Vaults should be underlain with approxi- mately 1 foot of crushed rock. 8.4. Seismic Design Parameters Proposed improvements should be designed in accordance with the requirements of govern- ing jurisdictions and applicable building codes. Table 3 presents the seismic design parameters for the site in accordance with CBC (2007) guidelines and mapped spectral ac- celeration parameters (USGS, 2009).

Corrosion Laboratory testing was perfonned on two representative samples· of the on-site soils to evaluate pH and electrical resistivity, as weU as chloride and sulfate contents. The pH and electrical resistivity tests were perfonned in accordance with the California Test (CT) 643 and the sulfate and chloride content tests were perfonned in accordance with CT 417 and 422, respectively. These laboratory test results are presented in Appendix B. The results of the corrosivity testing indicated that the electrical resistivity ranged from 850 to 3,000 ohm-cm, a soil pH of 6.9, a chloride content range of 250 to 290 parts per mil- lion (ppm) and a sulfate content range of 0.006 to 0.060 percent (i.e., 60 to 600 ppm). Based on the Caltrans (2003) criteria, the project site would not be classified as corrosive, which is 10664100I R.dac 16 - - - - - El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 defined as a site having soils with more than 500 ppm of chlorides, more than 0.2 percent sulfates or a pH less than 5 .5. 8.6. Concrete Concrete in contact with soil or water that contains high concentrations of water-soluble sulfates can be subject to premature chemical and/or physical deterioration. The soil samples tested in this evaluation indicated water-soluble sulfate content range of 0.006 to 0.060 per- cent (i.e., 60 to 600 ppm). Based on the American Concrete Institute (ACI) criteria (2008), the potential for sulfate attack is negligible for water-soluble sulfate contents in soils ranging from about 0.0 to 0.10 percent by weight (0 to 1,000 ppm) and Type II cement may be used for concrete construction. However, due to the variability of site soils, consideration should be given to using Type IIN cement and concrete with a water-cement ratio no higher than 0.45 by weight for normal weight aggregate concrete and a 28-day compressive strength of 4,500 pounds per square inch or more for the project. A 3-inch thick concrete cover should be maintained over reinforcing steel where concrete is in contact with soil in accordance with Section 7.7 ofACI Committee 318 (ACI, 2008). 8.7. Pre-Construction Conference We recommend that a pre-construction meeting be held prior to commencement of construc- tion activities. The owner or his representative, the agency representatives, the architect, the civil engineer, Ninyo & Moore, and the contractor should be in attendance to discuss the plans, the project, and the proposed construction schedule. 8.8. Plan Review and Construction Observation The conclusions and recommendations presented in this report are based on analysis of ob- served conditions in widely spaced exploratory excavations. If conditions are found to vary from those described in this report, Ninyo & Moore should be notified, and additional recom- mendations will be provided upon request. Ninyo & Moore should review the final project 106641001 R.doc 17 El Camino Real Widening, Retaining Walls A and B Carlsbad, California October 15, 2009 Project No. 106641001 drawings and specifications prior to the commencement of construction. Ninyo & Moore should perform the needed observation and tc~sting services during construction operations. The recommendations provided in this report are based on the assumption that Ninyo & Moore will provide geotechnical observation and testing services during construction. In the event that it is decided not to utilize the services ofNinyo & Moore during construction, we request that the selected consultant provide the client with a letter (with a copy to Ninyo & Moore) indicating that they fully understm11d Ninyo & Moore's recommendations, and that they are in full agreement with the design parameters and recommendations contained in this report. Construction of proposed improvements should be performed by qualified subcon- tractors utilizing appropriate techniques and construction materials. 9.

Bulk Samples Bulle samples of representative earth materials were obtained from the exploratory borings. The samples were bagged and transported to the laboratory for testing. The Standard Penetration Test Sampler Disturbed drive samples of earth materials were obtained by means of a Standard Penetra- tion Test sampler. The sampler is composed of a split barrel with an external diameter of 2 inches and an unlined internal diameter of 1-3/8 inches. The sampler was driven into the ground 12 to 18 inches with a 140-pound hammer free-falling from a height of 30 inches in general accordance with ASTM D 1586. The blow counts were recorded for every 6 inches of penetration; the blow counts reported on the logs are those for the last 12 inches of pene- tration. Soil samples were observed and removed from the sampler, bagged, sealed and transported to the laboratory for testing. Field Procedure for the Collection of Relatively Undisturbed Samples Relatively undisturbed soil samples were obtained in the field using the following method. The Modified Split-Barrel Drive Sampler The sampler, with an external diameter of 3.0 inches, was lined with 1-inch long, thin brass rings with inside diameters of approximately 2.4 inches. The sample barrel was driven into the ground with the weight of a hammer in general accordance with ASTM D 3550. The driving weight was permitted to fall freely. The approximate length of the fall, the weight of the hammer, and the number of blows per foot of driving are presented on the boring logs as an index to the relative resistance of the materials sampled. The samples were removed from the sample barrel in the brass rings, sealed, and transported to the laboratory for testing. 10664100111..doc • - - 0 15 XX/XX ....J 0 ID :::? &'5 z 0 i= . ~ "-l -0 LL • ~~ (.)

SITE AND PROJECT DESCRIPTION December 31, 2009 Project No. 106641002 The proposed cut and fill slopes are located along the east side of El Camino Real at approximate Stations 529+50 to 536+00, south of Chestnut Avenue in Carlsbad, California (Figure 2). The prop- erty east of El Camino Real consists of ascending slopes rising from the roadway to a relatively flat property above. The northern portion of the existing slope is near vertical and the southern portion is moderately sloped. An asphalt concrete driveway extends from the roadway to the property above. The parcel is currently vacant, however, remnants of a previous structure remain. Elevations range from a low of approximately 230 feet above mean sea level (MSL) along El Camino Real at the south end of the site to a high of approximately 290 feet MSL at the top of the existing slope. Vegeta- tion generally consists of a sparse to moderate growth of grass, weeds, brush, and trees. 4. SUBSURFACE EVALUATION AND LABO RA TORY TESTING Our subsurface evaluation was conducted on November 5, 2009 and consisted of excavating six -exploratory test pits with a backhoe to depths of up to approximately 17 feet. The test pit loca- tions were selected based on the results of our background review, field reconnaissance, and the anticipated grading at the site. Prior to commencing the subsurface evaluation, USA was notified for mark-out of the existing utilities. The approximate locations of the test pits are presented on Figure 2. The test pit logs are presented in Appendix A. - Laboratory testing of representative soil samples included an evaluation of in-place moisture and density, grain size analysis, and shear strength. The results of the in-situ dry density and moisture content tests are presented on the test pit logs in Appendix A. The results of the other laboratory tests performed are presented in Appendix B. 5. GEOLOGY AND SUBSURFACE CONDITIONS Our findings regarding regional and site geology and groundwater conditions at the subject site are provided in the following sections. 106641002 R.doc 2 El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 5.1. Regional and Geologic Setting The project area is situated in the San Diego County coastal section of the Peninsular Ranges Geomorphic Province. This geomorphic province encompasses an area that extends approxi- mately 900 miles from the Transverse Ranges and the Los Angeles Basin south to the southern tip of Baja California (Norris and Webb, 1990). The province varies in width from approxi- mately 30 to 100 miles. In general, the province consists of rugged mountains underlain by Jurassic meta volcanic and metasedimentary rocks, and Cretaceous igneous rocks of the south- ern Californ\a batholith. The portion of the province in San Diego County that includes the project area consists generally of Quaternary and Tertiary sedimentary rock. 5.2. Site Geology Geologic units encountered during our reconnaissance and subsurface evaluation included fill, very old paralic deposits, and materials of the Santiago Formation. Generalized descriptions of the units encountered are provided in the subsequent sections. More detailed descriptions are provided on the test pit logs in Appendix A. I 06641002 R.doc 5.2.1. Fill Fill was encountered in our test pits from approximately 1 foot to depths ofup to 15 feet. As observed and encountered, the materials generally consisted of light brown, <hy to moist, loose, silty fine to medium sand. Scattered to abundant construction debris is present within the fill including concrete, asphalt concrete, steel, rebar, glass, and wood. 5.2.2. Very Old Paralic Deposits Very old paralic deposits were encountered from the surface in test pits TP-1 to a depth of approximately 8.5 feet and beneath the fill in test pits TP-2 and TP-3 to depths of ap- proximately 6.5 and 12.4 feet, respectively. As encountered, the materials generally consisted of light reddish brown, damp, moderately cemented, silty fine-to coarse- grained sandstone with scattered layers of gravel and cobbles. 3 - - - El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 5.2.3. Santiago Formation Materials of the Santiago Formation were encountered in test pits TP-1 through TP-3 under- lying the very old paralic deposits and in TP-6 underlying the fill to the depths explored. As encountered, the materials generally consisted of light brown, damp to moist, weakly ce- mented, silty, fine-to medium-grained sandstone. Mudstone beds are commonly encountered within the sandier portions of the Santiago Formation. Previous consultants ( Geosoils, Inc. 1989) mapped such a mudstone bed at the toe of the existing cut slope north of the entrance driveway. This bed is currently covered by erosional debris and we could not confirm its presence: Materials of the Santiago Formation were also observed in the ex- isting cut slope along El Camino Real beneath the very old paralic deposits and fill. 5.3. Groundwater Groundwater was not encountered in our test pits during the time of our exploration. Based on our background review of the site, regional groundwater is estimated to be located at a depth in excess of 20 feet below the ground surface. Evidence of seepage was noted at the toe of the slope just north of the site. Fluctuations in the groundwater level may occur due to variations in ground surface topography, subsurface geologic conditions and structure, rain- fall, irrigation, and other factors. Seepage, particularly at geologic contacts, should be anticipated based on site geology and topography. 6. GEOLOGIC HAZARDS In general, hazards associated with seismic activity include ground surface rupture, strong ground motion, tsunamis, and liquefaction. These considerations and other geologic hazards such as landsliding are discussed in the following sections. 6.1. Faulting and Seismicity The project area is considered to be seismically active. Based on our review of the referenced geologic maps and stereoscopic aerial photographs, as well as our geologic field reconnais- sance, the subject site is not underlain by known active or potentially active faults (i.e., faults 10664 I 002 R.doc 4 JVln90,<-JY\OO\"e El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 that exhibit evidence of ground displaceme:nt in the last 11,000 years and 2,000,000 years, re- spectively). Major known active faults in the region consist generally of en-echelon, northwest-striking, right-lateral, strike-slip faults. These include the San Clemente, Agua Blanca-Coronado Bank, Newport-Inglewood, and Rose Canyon faults, located to the west of the site, and the Whittier-Elsinore, San Jacinto, and San Andreas faults, located to the east of the site. The locations of these faults are shown on Figure 3. The nearest known active fault is the Rose Canyon fault system, located approximately 6 miles west of the site, which can generate an earthquake magnitude ofup to 7.2 (Cao, et al., 2003). 6.1.1. Strong Ground Motion The 2007 California Building Code (CBC) recommends that the design of structures be based on the peak horizontal ground acceleration (PGA) having a 2 percent probability of exceedance in 50 years, which is defined as the Maximum Considered Earth- - quake (MCE). The statistical return period for PGAMcE is approximately 2,475 years. The - Design Earthquake (PGA0E) corresponds to two-thirds of the PGAMcE, and this value is typically used for residential and commercial structures. Based on our review of subsur- face data, the project site corresponds to a Site Class C. The site modified PGAMcE and PGAoE were estimated to be 0.49g and 0.33g, respectively, using the United States Geo- logical Survey (USGS) (USGS, 2009) ground motion calculator (web-based). These estimates of ground motion do not include near-source factors that may be applicable to the design of structures on site. 6.1.2. Ground Surface Rupture Based on our review of the referenced. literature and our site reconnaissance, no active faults are known to cross the project site. Therefore, the potential for ground rupture due to faulting at the site is unlikely. However, lurching or cracking of the ground surface as a result of nearby seismic events is possible. I 06641002 R.doc 5 - - - El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 7. 6.1.3. Liquefaction and Seismically Induced Settlement Liquefaction of cohesionless soils can be caused by strong vibratory motion due to earthquakes. Research and historical data indicate that loose granular soils and non- plastic silts that are saturated by a relatively shallow groundwater table are susceptible to liquefaction. Based on the dense nature of the formational materials underlying the site and the estimated depth to groundwater, the potential for liquefaction or seismically induced settlement is not a design consideration. 6.2. Landsliding Based on our review of published geologic literature and aerial photographs, and our geo- logic reconnaissance, landslides or related features have not been recognized as underlying the project site. SLOPE STABILITY Both surficial and global stability analyses were performed for the existing and proposed slope con- figuration. The intent of the stability analysis was to evaluate the potential for deep seated failures of the slope. Global stability analyses for the proposed slope configurations were performed using the surface and subsurface profile of geologic units based on the preliminary project plans and the results of our field exploration. Global stability analysis was performed on cross sections A-A: and B-B'a representative section where the 1.5:1 (horizontal:vertical) cut slope is about 14 feet high, and a pro- posed fill slope is planned at an inclination of 1.5: 1 up to about 50 feet high. The intent of the global stability analysis was to evaluate the potential for deep-seated, rotational (Simplified Janbu type) or bedding plane failures through Santiago Formation or fill materials. A two-dimensional stability analysis program, GSTABL7, was used for this purpose. The design factors of safety under static and pseudo-static loading conditions were 1.5 and 1.1, respectively, following accepted geotechnical practices and agency guidelines. A horizontal acceleration coef- ficient of 0.15g was used to evaluate the pseudo-static stability. The bedrock layers were 106641002 R.doc 6 El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 assigned homogeneous, isotropic strength properties derived from laboratory direct shear tests performed during this evaluation. Our global stability analyses indicate that the proposed cut and fill slopes up to 1.5:1 inclination have adequate factors of safety under static and pseudo-static loading conditions provided the recommendations presented in this report are implemented into project design and construction. 8. CONCLUSIONS AND RECOMMENDATIONS Based on our review of the referenced background data, geologic field reconnaissance, and sub- surface exploration, it is our opinion that construction of the proposed project is feasible from a geotechnical standpoint. Geotechnical considerations include the following: • Although the current cut slope has performed adequately in its near vertical state, the pro- posed cut slope will expose adversely dipping bedding within the Santiago Formation, particularly a reported mudstone depositional bed which possesses poor strength parameters. Additionally, erosion which has affected the current steepened slope will continue to affect the proposed 1.5: 1 cut slope as vegetation will be very difficult to establish in sandstone. • In order to mitigate the marginal stability and erosion potential of the proposed 1.5: 1 cut slope, we recommend that the cut slope be overcut and replaced as a geogrid reinforced fill slope planted appropriately in accordance with the recommendations of the landscape archi- tect. However, steepened slopes will need increased maintenance and will be difficult on which to establish vegetation. • The proposed fill slope on the southern portion of the site will overlie existing dumped fill mate- rials. Our slope stability analysis indicates that these dumped fill materials should be removed as indicated on Figure 3 to provide a fill slope condition with an appropriate factor of safety. • The proposed earthwork should be feasiblt! with earthmoving equipment in good working order. However, strongly cemented zones within the very old paralic deposits or materials of the Santiago Formation may be encountered which would entail the use of heavy ripping or rock breakers. • Although groundwater was not encountered during our subsurface evaluation, evidence of seepage was observed north of the site and should be anticipated, particularly at geologic contacts, during grading. 106641002 R.doc ,, , l(ln90& l,\OO~e - - - El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 • The existing materials derived from the very old paralic deposits and Santiago Formation are generally considered suitable for reuse as engineered fill provided that they are processed and prepared in accordance with the following recommendations. • The on-site fill materials are generally not considered suitable for reuse as engineered fill unless processed to remove the abundant asphalt, concrete, metal, and wood debris within the fill. • Our analysis indicates that the factor of safety against surficial instability is marginal (not more than 1.5) for the proposed slope inclination of 1.5:1. Therefore, recommendations are provided herein for geogrid reinforced slopes. • The site is subject to strong ground motion in the event of a nearby major earthquake. • Earthquake induced liquefaction is not considered a design consideration due to the density and consistency of soils encountered during our subsurface exploration and the depth to the groundwater table. • The potential for landsliding or an earthquake induced landslide is considered low. Based on the results of our subsurface evaluation and our understanding of the proposed grading, -we present the following geotechnical recommendations relative to the design and construction of the proposed slopes. The proposed grading should also be performed in accordance with the requirements of applicable governing agencies. - 8.1. Earthwork In general, earthwork should be performed in accordance with the recommendations pre- sented in this report. Ninyo & Moore should be contacted for questions regarding the recommendations or guidelines presented herein. 106641002 R.doc 8.1.1. Site Preparation Prior to excavation, the project site should be cleared of surface obstructions, existing pave- ment sections, and stripped of rubble, debris, vegetation, any loose, wet, or otherwise unstable soils, as well as surface soils containing organic material. Existing utilities within the project limits should be abandoned, rerouted, or protected from damage by construction activities. Obstructions that extend below finish grade, if any, should be removed and the resulting holes 8 El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 filled with compacted soils. Materials generated from the clearing operations should be re- moved from the site and disposed of at a legal dumpsite away from the project area. 8.1.2. Treatment of Proposed Cut Slopes We recommend that the proposed 1.5: 1 cut slope be overcut and replaced as a geogrid re- inforced stability fill slope. The stability fill should be constructed as recommended in the Slopes section of this report. I Oo64 l 002 R.doc 8.1.3. Excavation Characteristics We anticipate that excavation of the site materials can generally be accomplished with heavy construction equipment in good operating condition. Strongly cemented zones within the very old paralic deposits and Santiago F01mation (concretions) may be encoun- tered at the site and will be difficult to rip. The use of heavy ripping and/or rock breaking equipment should be anticipated. As a result, oversize material may be generated. 8.1.4. Materials for Fill On-site soils relatively free of organics are suitable for reuse as fill. Fill material should generally not contain rocks or lumps over approximately 3 inches, and generally not more than approximately 30 percent larger than 3/4 inch. Utility trench backfill material should not contain rocks or lumps over approximately 3 inches in general. Soils classi- fied as silts or clays should not be used. Larger chunks, if generated during excavation, may be broken into acceptably sized pi,eces or disposed of off site. Imported fill material, if needed for the project, should generally be granular soils with a very low to low expansion potential (i.e., an EI of 50 or less as evaluated by the American Society for Testing and Materials [ ASTM] D 4829). Import material should also be non-corrosive in accordance with the Caltrans (2003) corrosion guidelines. Ma- terials for use as fill should be evaluated by Ninyo & Moore's representative prior to filling or importing. 9 - - - - - El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 106641002 R.uoc 8.1.5. Compacted Fill Prior to placement of compacted fill, the contractor should request an evaluation of the exposed ground surface by Ninyo & Moore. Unless otherwise recommended, the exposed ground surface should then be scarified to a depth of approximately 8 inches and watered or dried, as needed, to achieve moisture contents generally above the op- timum moisture content. The scarified materials should then be compacted to a relative compaction of 90 percent as evaluated in accordance with ASTM D 1557. The evaluation of compaction by the geotechnical consultant should not be considered to preclude any requirements for observation or approval by governing agencies. It is the contractor's responsibility to notify the geotechnical consultant and the appropriate governing agency when the project area is ready for observation, and to provide rea- sonable time for that review. Fill materials should be moisture conditioned to generally above the laboratory opti- mum moisture content prior to placement. The optimum moisture content will vary with material type and other factors. Moisture conditioning of fill soils should be generally consistent within the soil mass. Prior to placement of additional compacted fill material following a delay in the grading operations, the exposed surface of previously compacted fill should be prepared to receive fill. Preparation may include scarification, moisture conditioning, and recompaction. Compacted fill should be placed in horizontal lifts of approximately 8 inches in loose thickness. Prior to compaction, each lift should be watered or dried as needed to achieve a moisture content generally above the laboratory optimum, mixed, and then compacted by mechanical methods, using sheepsfoot rollers, multiple-wheel pneumatic-tired rollers or other appropriate compacting rollers, to a relative compaction of 90 percent as evalu- ated by ASTM D 15 57. Successive lifts should be treated in a like manner until the desired finished grades are achieved. 10 l(inga"' JV\OOl"e El Camino Real Widening, Sprague Property Carlsbad, California 8.1.6. Slopes December 31, 2009 Project No. 106641002 Cut and fill slopes should not be steeper than 2: 1, unless otherwise recommended by Ninyo & Moore and approved by the regulating agencies. Steepened slopes may be con- structed up to an inclination of 1.5:1 if reinforced with geogrid. Steepened slopes should be constructed upon a key excavated to a width of 30 feet and a depth of 1 foot into competent formational materials. The back cut should be benched. We recommend that a geogrid such as Tensar LH800 or equivalent be incorporated into the slope at 2-foot vertical increments and extend into the fill 8 feet from the slope face. The fill should be granular material, com- pacted as recommended in the Compact,ed Fill section of this report, and planted. Compaction of the face of slopes should be performed by overbuilding and cutting back the slope face. Alternatively, the slopt: face may be compacted by backrolling at inter- vals of 4 feet or less in vertical slopi;! height, or as dictated by the capability of the available equipment, whichever is less. Fill slopes should be backrolled utilizing a con- ventional sheepsfoot-type roller. Care should be taken to maintain the desired moisture conditions and/or reestablish them, as needed, prior to backrolling. I 06641002 R.doc 8.1.7. Site Runoff Site runoff should not be permitted to flow over the tops of slopes. Positive drainage should be established away from the top of slopes. This may be accomplished by utiliz- ing brow ditches placed at the top of slopes to divert surface runoff away from the slope face where drainage devices are not otherwise available. The on-site soils will be highly susceptible to erosion. Therefore, the project plans and specifications should contain design features and construction requirements to mitigate erosion of on-site soils during and after construction. Slopes and other exposed ground surfaces should be appropriately planted with protective ground cover consisting of a combination of shallow and deep rooted vegetation in accordance with the landscape architect's recommendations. The erosiion potential of the slope face may be improved by considering the use of an intermediate geogrid or geotextile. 11 - - - - El Camino Real Widening, Sprague Property Carlsbad, California 8.2. Pre-Construction Conference December 31, 2009 Project No. 106641002 We recommend that a pre-construction meeting be held prior to commencement of construc- tion activities. The owner or his representative, the agency representatives, the architect, the civil engineer, Ninyo & Moore, and the contractor should be in attendance to discuss the plans, the project, and the proposed construction schedule. 8.3. Plan Review and Construction Observation The conclusions and recommendations presented in this report are based on analysis of ob- served conditions in widely spaced exploratory excavations. If conditions are found to vary from those described in this report, Ninyo & Moore should be notified, and additional recom- mendations will be provided upon request. Ninyo & Moore should review the final project drawings and specifications prior to the commencement of construction. Ninyo & Moore should perform the needed observation and testing services during construction operations. The recommendations provided in this report are based on the assumption that Ninyo & Moore will provide geotechnical observation and testing services during construction. In the event that it is decided not to utilize the services ofNinyo & Moore during construction, we request that the selected consultant provide the client with a letter (with a copy to Ninyo & Moore) indicating that they fully understand Ninyo & Moore's recommendations, and that they are in full agreement with the design parameters and recommendations contained in this report. Construction of proposed improvements should be performed by qualified subcon- tractors utilizing appropriate techniques and construction materials. 9. LIMITATIONS The field evaluation, laboratory testing, and geotechnical analyses presented in this geotechnical report have been conducted in general accordance with current practice and the standard of care exercised by geotechnical consultants performing similar tasks in the project area. No warranty, expressed or im- plied, is made regarding the conclusions, recommendations, and opinions presented in this report. There is no evaluation detailed enough to reveal every subsurface condition. Variations may exist and 106641002 R.doc 12 El Camino Real Widening, Sprague Property Carlsbad, California December 31, 2009 Project No. 106641002 conditions· not observed or described in this report may be encountered during construction. Uncertain- ties relative to subsmface conditions can be reduced through additional subsmface exploration. Additional subsmface evaluation will be performed upon request.

The Modified Split-Barrel Drive Sample][ The sampler, with an external diameter of 3.0 inches, was lined with 1-inch long, thin brass rings with inside diameters of approximately 2.4 inches. The sample barrel was driven into the ground with the weight of a hammer. The driving weight was permitted to fall freely. The samples were removed from the sampl,e barrel in the brass rings, sealed, and transported to the laboratory for testing. 106641002 R.doc - - -r, G5 C ::0 m .., ' ,_, ~· ----7r-~~re Explanation of Test Pit, Core, Trench and Hand Auger Log Symbols PROJECT NO.

Soil classifications are indicated on the logs of the exploratory test pits in Appendix A. In-Place Moisture and Density Tests The moisture content and dry density of relatively undisturbed samples obtained from the ex- ploratory borings were evaluated in general accordance with ASTM D 2937. The test results are presented on the logs of the exploratory test pits in Appendix A. Gradation Analysis Gradation analysis tests were performed on selected representative soil samples in general accor- dance with ASTM D 422. The grain-size distribution curves are shown on Figures B-1 and B-2. These test results were utilized in evaluating the soil classifications in accordance with the Uni- - fied Soil Classification System (USCS). - Direct Shear Test A _direct shear test was performed on a relatively undisturbed sample in general accordance with ASTM D 3080 to evaluate the shear strength characteristics of selected material. The sample was inundated during shearing to represent adverse field conditions.

The Permittee shall clearly mark the limits of the workspace with flagging or similar means to ensure mechanized equipment does not enter avoided waters of the U.S. Adverse impacts to waters of the U.S. beyond the Corps-approved construction footprint are not authorized. Such impacts could result in permit suspension or revocation; administrative, civil or criminal penalties; and/or substantial, additional, compensatory mitigation requirements. Endangered Species Act and Migratory Bird Treaty Act: 2. This Corps permit does not authorize the take of any federally listed species as threatened or endangered species, or adversely modify their designated critical habitat. In order to legally take a listed species, you must have separate authorization under the Endangered Species Act (ESA) {e.g. ESA Section 10 permit, or a Biological Opinion (BO) under ESA Section 7, with "incidental take" provisions with which you must comply]. Cultural Resources: 3. Pursuant to 36 C.F .R. section 800.13, in the event of any discoveries during construction activities of human remains, archeological deposits, or any other type of historic property, the Permittee shall notify the Corps Project Manager, Ms. Shanti Santulli at 760-602-4834 and the Corps Archeology Staff, Steve Dibble at 213-452-3849, John Killeen at 213-452-3861, or Amy Holmes 213-452-3855, within 24 hours of the find.

TERMS AND CONDITIONS 1. Nationwide Permit(s) NWP 14 Linear Transportation Projects. Terms: Your activity is authorized under Nationwide Permit Number(s) NWP 14 Linear Transportation Projects subject to the following temlS: 14. Linear Transportation Projects. Activities required for the construction, expansion, modification, or improvement of linear transportation projects (e.g., roads, highways, railways, trails, airport runways, and taxiways) in waters of the United Stat:es. For linear transportation projects in non-tidal waters, the discharge cannot cause the loss of greater than 1/l-acre of waters of the United States. For linear transportation projects in tidal waters, the discharge caimot cause the 1065 of greater than 1/3-acre of waters of the United States. Any stream channel modification, including bank stabilization, is limited to the minimum necessary to construct or protect the linear transportation project; such modifications must be in the immediate vicinity of the project. This NWP also authorizes temporary structures, fills, and work necessary to construct the linear transportation project. Appropriate measures must be taken to maintain normal downstream flows and minimize flooding to the maximum extent practicable, when temporary structures, work, and discharges, including cofferdams, are necessary for construction activities, access fills, or dewatering of construction sites. Temporary fills must consist of materials, and be placed in a manner, that will not be eroded by expected high flows. Temporary fills must be removed in their entirety and the affected areas returned to pre-construction elevations. The areas affected by temporary fills must be revegetated, as appropriate. 'This NWP cannot be used to authoril~ non-linear features commonly associated with transportation projects, such as vehicle maintenance or storage buildings, parking lots, train stations, or aircraft hangars. Notification: The permittee must submit a pre-construction notification to the district engineeJ· prior to commencing the activity if: (1) the loss of waters of the United States exceeds 1/10 acre; or (2) there is a discharge in a spedal aquatic site, including wetlands. (See general rondition 27.) (Sections 10 and 404) Note: Some discharges for the construction of farm roads or forest roads, or temporary roads for moving mining equipment. may qualify for an exemption under Section 404(f) of the Qean Water Act (see 33 CFR 323.4). Note: To qualify for NWP authorization, the prospective permittee must comply with the following general conditions, as appropriate, in addition to any regional or case-specific conditions imposed by the division engineer or district engineer. Prospective permittees should contact the appropriate Corps district office to determine if regional conditions have been imposed on an NWP. Prospective permittees should ah10 contact the appropriate Corps district office to determine the status of Oean Water Act Section 401 water quality - certification and/or Coastal Zone Management Act consistency for an NWP. 2. Nationwide Permit General Conditions: The following general conditions must be followed in order for any authorization by an NWP to be valid: 1. Nll'Digation. (a) No activity may cause more than a minimal adverse effect on navigation. (b) Any safety lights and signals prescribed by the U.S. Coast Guard, through regulations or otherwise, must be installed and maintained at the permittee's expense on authorized facilities in navigable waters of the United States. (c) The permittee understands and agrees that. if future operations by the United States require the removal, relocation, or other alteration, of the structure or work herein authorized, or if, in the opinion of the Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters, the permittee will be required, upon due notice from the Corps of Engineers, to remove, relocat:e, or alter the structural work or obstructions caused thereby, without expense to the United States. No claim shall be made against the United States on account of any such removal or alteration. 2. Aqu4ltic Lift Movements. No activity may substantially disrupt the necessary life cycle movements of those species of aquatic life indigenous to the waterbody, including those species that normally migrate through the area, unless the activity's primary purpose is to impound water. Culverts placed in streams must be installed to maintain low flow conditions. 3. Spmoning Areas. Activities in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the physical destruction (e.g., through excavation, fill, or downstream smothering by substantial turbidity) of an important spawning area are not authorwed. 4. Migratory Bird Brading Areas. Activities in waters of the United States that serve as breeding areas for migratory birds must - - - - 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. be avoided to the maximum extent practicable. Shellfish Beds. No activity may occur in areas of concentrated shellfish populations, unless the activity is directly related to a shellfish harvesting activity authorized by NWPs 4 and 48. Suitable Material No activity may use unsuitable material (e.g., trash, debris, car bodies, asphalt, etc.). Material used for construction or discharged must be free from toxic pollutants in toxic amounts (see Section 307 of the Oean Water Act). Water Supply Intakes. No activity may occur in the proximity of a public water supply intake, except where the activity is for the repair or improvement of public water supply intake structures or adjacent bank stabilization. Adverse Effects From Impoundmtnts. 1f the activity creates an impoundment of water, adverse effects to the aquatic system due to accelerating the passage of water, and/or restricting its flow must be minimized to the maximum extent practicable. Management of Water Flows. To the maximum extent practicable, the preconstruction course, condition, capacity, and location of open waters must be maintained for each activity, including stream channelization and storm water management activities, except as provided below. The activity must be constructed to withstand expected high flows. The activity must not restrict or impede the passage of normal or high flows, unless the primary purpose of the activity is to impound water or manage high flows. The activity may alter the preconstruction course, condition, capacity, and location of open waters if it benefits the aquatic environment (e.g., stream restoration or relocation activities). Fills Within 100-Year Floodplains. The activity must comply with applicable FEMA-approved state or local floodplain management requirements. Equipment. Heavy equipment working in wetlands or mudflats must be placed on mats, or other measures must be taken to minimize soil disturban~. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used and maintained in effective operating condition during construction, and all exposed soil and other fills, as well as any work below the ordinary high water mark or high tide line, must be permanently stabilized at the earliest practicable date. Permittees are encouraged to perform work within waters of the United States during periods of low-flow or no-flow. Rem6val of Temporary Fills. Temporary fills must be removed in their entirety and the affected areas returned to pre- construction elevations. The affected areas must be revegetated, as appropriate. Proper Maintenance. Any authorized structure or fill shall be properly maintained, including maintenance to ensure public safety. Wild and Scenic Rivers. No activity may occur in a component of the National Wild and Scenic River System, or in a river officially designated by Congress as a "study river" for possible inclusion in the system while the river is in an official study status, unless the appropriate Federal agency with direct management responsibility for such river, has determined in writing that the proposed activity will not adversely affect the Wild and Scenic River designation or study status. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency in the area (e.g., National Park Service, U.S. Forest Service, Bureau of Land Management, U.S. Fish and Wildlife Service). 16. Tribal Rights. No activity or its operation may impair reserved tribal rights, including, but not limited to, reserved water rights and treaty fishing and hunting rights. 17, Endangered Species. (a) No activity is authorized under any NWP which is likely to jeopardize the continued existence of a threatened or endangered species or a species proposed for such designation, as identified under the Federal Endangered Species Act (ESA), or which will destroy or adversely modify the critical habitat of such species. No activity is authorized under any NWP which "may affect" a listed species or criticaJ habitat, unless Section 7 consultation addressing the effects of the proposed activity has been completed. (b) Federal agencies should follow their own procedures for complying with the requirements of the ESA. Federal permittees must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. (c) Non-federal permittees shall notify the district engim!er if any listed species or designated critical habitat might be affected A or is in the vicinity of the project, or if the project is located in designated critical habitat, and shall not begin work on the • activity until notified by the district engineer that the requirements of the ESA have been satisfied and that the activity is authorized. For activities that might affect Federally-lisb:!d endangered or threatened species or designated critical habitat, the pre-construction notification must include the name(s) of the endangered or threatened species that may be affected by the proposed work or that utilize the designated critical habitat that may be affected by the proposed work. The district engineer will determine whether the proposed activity "may affect" or will have "no effect" to listed species and designated critical habitat and will notify the non-Federal applicant of the Corps' determination within 45 days of receipt of a complete pre- construction notification. In cases where the non-Federal applicant has identified listed species or critical habitat that might be affected or is in the vicinity of the project, and has so notified the Corps, the applicant shal1 not begin work until the Corps has provided notification the proposed activities will have "no effect" on listed species or critical habitat, or until Section 7 consultation has been completed. {d) As a result of formal or informal consultation with the FWS or NMFS the district engineer may add spedesspecific regional endangered species conditions to the NWPs. (e) Authorization of an activity by a NWP does not authorize the "take" of a threatened or endangered species as defined under t:he ESA. In the absence of separate authorization ( e.g., an ESA Section 10 Permit, a Biological Opinion with "incidental take" provisions, etc.) from the U.S. FWS or the NMFS, both lethal and non- lethal "takes" of protected species are in violation of the ESA. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the U.S. FWS and NMFS or their world wide Web pages at http://www.fws.gov/ and http://www.nOR11.guvlfismries.html respectively. 18. Historic Properties. (a) In cases where the district engineer determines that the activity may affect properties listed, or eligible for listing, in the National Register of Historic Places, the activity is not authorized, until the requirements of Section 106 of the National Historic Preservation Act (NHPA) have been satisfied. (b) Federal permittees should follow their own procedurt:!S for complying with the requirements of Section 106 of the National Historic Preservation Act. Federal permittees must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. - (c) Non-federal permittees must submit a pre-construction notification to the district engineer if the authorized activity may have the potential to cause effects to any historic properties listed, determined to be eligible for listing on, or potentially eligible for listing on the National Register of Historic Places, including previously unidentified properties. For such activities, the preconstruction notification must state which historic properties may be affected by the proposed work or include a vicinity map indicating the location of the historic properties or the potential for the presence of historic properties. Assistance regarding information on the location of or potential for the presence of historic resources can be sought from the State Historic Preservation Officer or Tribal Historic Preservation Officer, as appropriate, and the National Register of Historic Places (see 33 CFR 330.4(g)). The district engineer shall make a reasonable and good faith effort to carry out appropriate identification efforts, which may include background research, consultation, oral history interviews, sample field investigation, and field survey. Based on the information submitted and these efforts, the district engineer shall determine whether the proposed activity has the potential to cause an effect on the historic properties. Where the non-Federal applicant has identified historic properties which the activity may have the potential to cause effects and so notified the Corps, the non- Federal applicant shall not begin the activity until notified by the district engineer either that the activity has no potential to cause effects or that consultation under Section 106 of the NHPA has been completed. (d) The district engineer will notify the prospective perm:ittee within 45 days of receipt of a complete preconstruction notification whether NHP A Section 106 consultation is required. Section 106 consultation is not required when the Corps determines that the activity does not have the potential to cause effects on historic properties (see 36 CFR 800.3(a)). If NHPA section 106 consultation is required and will occur, the district engineer will notify the non-Federal applicant that he or she cannot begin work until Section 106 consultation is complleted. (e) Prospective permittees should be aware that section U0k of the NHPA (16 U.S.C. 470h-2(k)) prevents the Corps from granting a permit or other assistance to an applicant who, with intent to avoid the requirements of Section 106 of the NHP A, has intentionally significantly adversely affected a historic property to which the permit would relate, or having legal power to prevent it, allowed such significant adverse effect to occur, unless the Corps, after consultation with the Advisory Council on Historic Preservation (ACHP}, det:errnines that circumstances justify granting such assistance despite the adverse effect created or permitted by the applicant. If circumstances justify granting the assistance, the Corps is required to notify the ACHP and provide documentation specifying the circumstances, explaining the degree of damage to the integrity of any - - - - 19. historic properties affected, and proposed mitigation. This documentation must include any views obtained from the applicant, SHPO(fHPO, appropriate Indian tribes if the undertaking occurs on or affects historic properties on tribal lands or affects properties of interest to those tribes, and other parties known to have a legitimate interest in the impacts to the permitted activity on historic properties. Designated Critical Resource Waters. Critical resource waters include: NOAA-designated marine sanctuaries, National Estuarine Research Reserves, state natural heritage sites, and outstanding national resource waters or other waters officially designated by a state as having particular environmental or ecological significance and identified by the district engineer after notice and opportunity for public comment. The district engineer may also designate additional critical resource waters after notice and opportunity for comment. (a) Discharges of dredged or fill material into waters of the United States are not authorized by NWPs 7, 12, 14, 16, 17, 21, 29, 31, 35, 39, 40, 42, 43, 44, 49, and 50 for any activity within, or directly affecting, critical resource waters, including wetlands adjacent to such waters. (b) For NWPs 3, 8, 10, 13, 15, 18, 19, 22, 23, 25, 27, 28, 30, 33, 34, 36, 37, and 38, notification is required in accordance with general condition 27, for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters. The district engineer may authorize activities under these NWPs only after it is determined that the impacts to the critical resource waters will be no more than minimal. 20. Mitigation. The district engineer will consider the following factors when determining appropriate and practicable mitigation necessary to ensure that adverse effects on the aquatic environment are minimal: (a) The activity must be designed and constructed to avoid and minimize adverse effects, both temporary and permanent, to waters of the United States to the maximum extent practicable at the project site (i.e., on site). (b) Mitigation in all its forms (avoiding, minimizing, rectifying, reducing, or compensating) will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. (c) Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland losses that exceed 1/10 acre and require preconstruction notification, unless the district engineer determines in writing that some other form of mitigation would be more environmentally appropriate and provides a project-specific waiver of this requirement. For wetland losses of 1110 acre or less that require pre-construction notification, the district engineer may determine on a case-by-case basis that compensatory mitigation is required to ensure that the activity results in minimal adverse effects on the aquatic environment. Since the likelihood of success is greater and the impacts to potentially valuable uplands are reduced, wetland restoration should be the first compensatory mitigation option considered. ( d) For losses of streams or other open waters that require pre-construction notification, the district engineer may require compensatory mitigation, such as stream restoration, to ensure that the activity results in minimal adverse effects on the aquatic environment. (e) Compensatory mitigation will not be used to increase the acreage losses allowed by the acreage limits of the NWPs. For example, if an NWP has an acreage limit of 1,2 acre, it cannot be used to authorize any project resulting in the loss of greater than 1,2 acre of waters of the United States, even if compensatory mitigation is provided that replaces or restores some of the lost waters. However, compensatory mitigation can and should be used, as necessary, to ensure that a project already meeting the established acreage limits also satisfies the minimal impact requirement associated with the NWPs. (f) Compensatory mitigation plans for projects in or near streams or other open waters will normally include a requirement for the establishment, maintenance, and legal protection (e.g., conservation easements) of riparian areas next to open waters. In some cases, riparian areas may be the only compensatory mitigation required. Riparian areas should consist of native species. The width of the required riparian area will address documented water quality or aquatic habitat loss concerns. Normally, the riparian area will be 25 to 50 feet wide on each side of the stream, but the district engineer may require slightly wider riparian areas to address documented water quality or habitat loss concerns. Where both wetlands and open waters exist on the project site, the district engineer will determine the appropriate compensatory mitigation (e.g., riparian areas and/or wetlands compensation) based on what is best for the aquatic environment on a watershed basis. In cases where riparian areas are determined to be the most appropriate form of compensatory mitigation, the district engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland losses. (g) Permittees may propose the use of mitigation banks, in-lieu fee arrangements or separate activity-specific compensatory mitigation. In all cases, the mitigation provisions will specify the party responsible for accomplishing and/or complying with A the mitigation plan. W (h) Where certain functions and s~rvkes of waters of the, United States are permanently adversely affected, such as the conversion of a forested or scrub-shrub wetland to a herbaceous wetland in a permanently maintained utility line right-of- way, mitigation may be required to reduce the adverse effects of the project to the minimal level. 21. Water Quality. Where States and authorized Tribes, or EPA where applicable, have not previously certified compliance of an NWP with CWA Section 401, individual 401 Water Quality Certification must be obtained or waived (see 33 CFR 330.4(c)). The district engineer or State or Tribe may require additilonal water quality management measures to ensure that the authorized activity does not result in more than minimal degradation of water quality. 22. CORStal ZAne Management. In coastal states where an NWP has not previously received a state coastal zone management consistency concurrence, an individual state coastal zom! management consistency concurrence must be obtained, or a presumption of concurrence must occur (see 33 CFR 330.4(d)). The district engineer or a State may require additional measures to ensure that the authorized activity is consistent with state coastal zone management requirements. 23. Regional and Case-By-Case Conditions. The activity must comply with any regional conditions that may have been added by the Division Engineer (see 33 CFR 330.4(e)) and with any case specific conditions added by the Corps or by the state, Indian Tnl>e, or U.S. EPA in its section 401 Water Quality Certification, or by the state in its Coastal Zone Management Act consistency determination. 24. Use of Multiple Nationwide .Permits. The use of more than one NWP for a single and complete project is prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit. For example, if ,1 road crossing over tidal waters is constructed under NWP 14, with associated bank stabilization authorized by NWP 13, the maximum acreage Joss of waters of the United States for the total project cannot exceed 1/.3-acre. 25. Transfer of Nationwide Permit Verifications. If the permitteti sells the property associated with a nationwide permit verification, the permittee may transfer the nationwide permit verification to the new owner by submitting a letter to the appropriate A Corps district office to validate the transfer. A copy of tht! nationwide permit verification must be attached to the letter, and W the letter must contain the following statement and signature: "When the structures or work authorized by this nationwide permit are still in existence at the time the property is transferred, the terms and conditions of this nationwide permit, including any special conditions, will continue to be binding on the new owner(s) of the property. To validate the transfer of this nationwtde permit and the associated liabilities associated with compliance with its terms and conditions, have the transferee sign and date below." (Transferee) (D,1te) 26. Compliance Certification. Each permittee who received an NWP verification from the Corps must submit a signed certification regarding the oompleted work and any required mitigation. The certification form must be forwarded by the Corps with the NWP verification letter and will include: (a) A statement that the authorized work was done in accordance with the NWP authorization, including any general or specific conditions; (b) A statement that any required mitigation was completed in accordance with the permit conditions; and (c) The signature of the permittee certifying the completion of the work and mitigation. 27. Pre-Construction Notification. (a) Timing. Where required by the terms of the NWP, the prospective permittee must notify the district engineer by submitting a pre-construction notification (PCN) as early as possible. The district engineer must determine if the PCN is complete within 30 calendar days of the date of receipt arid, as a general rule, will request additional information necessary to make the PCN complete only once. However, if the prospective permittee does not provide all of the requested information, - ' - - - then the district engineer will notify the prospective permlttee that the PCN is still incomplete and the PCN review process will not commence until all of the requested information has been received by the district engineer. The prospective permittee shall not begin the activity: (1) Until notified in writing by the district engineer that the activity may proceed under the NWP with any special conditions imposed by the district or division engineer; or (2) If 45 calendar days have passed from the district engineer's receipt of the complete PCN and the prospective permittee has not received written notice from the district or division engineer. However, if the permittee was required to notify the Corps pursuant to general condition 17 that listed species or critical habitat might be affected or in the vicinity of the project, or to notify the Corps pursuant to general condition 18 that the activity may have the potential to cause effects to historic properties, the permlttee cannot begin the activity until receiving written notification from the Corps that is "no effect" on listed species or "no potential to cause effects" on historic properties, or that any consultation required under Section 7 of the Endangered Species Act (see 33 CFR 330.4(£)) and/or Section 106 of the National Historic Preservation (see 33 CFR 330.4(g)) is completed. Also, work cannot begin under NWPs 21, 49, or 50 until the permittee has received written approval from the Corps. lf the proposed activity requires a written waiver to exceed specified limits of an NWP, the permittee cannot begin the activity until the district engineer issues the waiver. If the district or division engineer notifies the permittee in writing that an individual permit is required within 45 calendar days of receipt of a complete PCN, the permittee cannot begin the activity until an individual permit has been obtained. Subsequently, the permittee's right to proceed under the NWP may be modified, suspended, or revoked only in accordance with the procedure set forth in 33 CFR 330.5(d)(2). (b) Contents of Pre-Construction Notification: The PCN must be in writing and include the following information: (1) Name, address and telephone numbers of the prospective permittee; (2) Location of the proposed project; (3) A description of the proposed project; the project's purpose; direct and indirect adverse environmental effects the project would cause; any other NWP(s), regional general permit(s), or individual permit(s) used or intended to be used to authorize any part of the proposed project or any related activity. The description should be sufficiently detailed to allow the district engineer to determine that the adverse effects of the project will be minimal and to determine the need for compensatory mitigation. Sketches should be provided when necessary to show that the activity complies with the terms of the NWP. (Sketches usually clarify the project and, when provided, result in a quicker decision.); (4) The PCN must include a delineation of special aquatic sites and other waters of the United States on the project site. Wetland delineations must be prepared in accordance with the current method required by the Corps. The permittee may ask the Corps to delineate the special aquatic sites and other waters of the United States, but there may be a delay if the Corps does the delineation, especially if the project site is large or rontains many waters of the United States. Furthermore, the 45 day period will not start until the delineation has been submitted to or completed by the Corps, where appropriate; (5) If the proposed activity will result in the loss of greater than 1110 acre of wetlands and a PCN is required, the prospective permittee must submit a statement describing how the mitigation requirement will be satisfied. As an alternative, the prospective permlttee may submit a conceptual or detailed mitigation plan; (6) If any listed species or designated critical habitat might be affected or is in the vicinity of the project, or if the project is located in designated critical habitat, for non-Federal applicants the PCN must include the name(s) of those endangered or threatened species that might be affected by the proposed work or utilize the designated critical habitat that may be affected by the proposed work. Federal applicants must provide documentation demonstrating compliance with the Endangered Species Act; and (7) For an activity that may affect a historic property listed on, determined to be eligible for listing on, or potentially eligible for listing on, the National Register of Historic Places, for non-Federal applicants the PCN must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. Federal applicants must provide documentation demonstrating compliance with Section 106 of the National Historic Preservation Act. (c) Form of Pre-COnstruction Notification: The standard individual permit application form (Form ENG 4345) may be used, but the completed application form must clearly indicate that it is a PCN and must include a11 of the information required in paragraphs (b )(1) through (7) of this general condition. A letter containing the required information may also be used. (d) Agency Coordination: (1) The district engineer will consider any comments from Federal and state agencies concerning the proposed activity's compliance with the terms and conditions of the NWPs and the need for mitigation to reduce the project's adverse environmental effects to a minimal level. (2) For all NWP 48 activities requiring pre-construction notification and for other NWP activities requiring preconstruction notification to the district engineer that result in the loss of greater than 1/.2-acre of waters of the United States, the district engineer will immediately provide (e.g., via facsimile transmission, overnight mail, or other expeditious manner) a copy of the PCN to the appropriate Federal or state offices (U.S. FWS, state natural resource or water quality agency, EPA, State Historic Preservation Officer (SHPO) or Tribal Historic Preservation Office (THPO), and, if appropriate, the NMFS). With the exception of NWP 37, these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the district engineer notice that they intend to provide substantive, site-specific· comments. If so contacted by an agency, the district engineer will wait an additional 15 calendar days befoni making a decision on the preconstruction notification. The district engineer will fully consider agency comments received within the specified time frame, but will provide no response to the resource agency, except as provided below. The district engineer will indicate in the adminii..irative record associated with ead, preconstruction notification that the resource ager.cies' concerns were considered. For NWP 37, the emergency watershed protection and rehabilitation activity may proceed immediately in cases where there is an unacceptable hazard to life or a significant loss of property or economic hardship will occur. The district engineer will consider any comments received to decide whether the NWP 37 authorization should be modified, suspended, or revoked in accordance with the procedures at 33 CFR 330.5. (3) In cases of where the prospective permittee is not a Federal agency, the district engineer wiU provide a response to NMFS within 30 calendar days of receipt of any Essential Fish Habitat conservation recommendations, as required by Section 305(b)(4)(B) of the Magnuson-Stevens Fishery Conservation and Management Act. (4) Applicants are encouraged to provide the Corps multiple copies of pre-construction notifications to expedite agency coordination. (5) For NWP 48 activities that require reporting, the district engineer will provide a copy of each report within 10 calendar days of receipt to the appropriate regional office of the NMFS. (e) District Engineer's Decision: In reviewing the PCN for the proposed activity, the district engineer will determine whether the activity authorized by the NWP will result in more than minimal individual or cumulative adverse environmental effects or may be contrary to the public interest. If the proposed activity requires a PCN and will result in a Joss of greater than 1110 acre of wetlands, the prospective permittee should submit a mitigation proposal with the PCN. Applicants may also propose compensatory mitigation for projects with smaller impa<:ts. The district engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed work are minimal. The compensatory mitigation proposal may be either conceptual or detailed. If the district engineer determines that the activity complies with the terms and conditions of the NWP and that the adverse effects on the aquatic environment are min~mal, after considering mitigation, the district engineer will notify the permittee and include any conditions the district engineer deems necessary. The district engineer must approve any comper.satory mitigation proposal before the permittee c:ommences work. If the prospective permittee elects to submit a comper.satory mitigation plan with the PCN, the district engineer will expeditiously review the proposed comper.satory mitigation plan. The district engineer must review the plan within 45 calendar days of receiving a complete PCN and determine whether the proposed mitigation would ensuire no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment (after consideration of the compensatory mitigation proposal) are determined by the district engineer to be minimal, the district engineer will provide a timely written response to the applicant. The response will state that the project can proceed under the terms and conditions of the NWP. If the district engineer determines that the adverse effects of the proposed work are more than minimal, then the district engineer will notify the applicant either: (1) That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an individual permit; (2) That the project is authorized under the NWP subject to the applicant's submission of a mitigation plan that would reduce the adverse effects on the aquatic environment to the minimal level; or (3) That the project is authorized under the NWP with specific modifications or conditions. Where the district engineer determines that mitigation is required to ensure no more than minimal adverse effects occur to the aquatic environment, the activity will be authorized within the 45-day PCN period. The authorization will include the necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation plan that would reduce the adverse effects on the aquatic environment to the minimal level. When mitigation is required, no work in waters of the United States may occur until the district engineer has approved a specific mitigation plan. 28. Single and Complete Project. The activity must be a single and complete project. The same NWP cannot be used more than once for the same single and complete project. - - - Regional Conditions for the Los Angeles District: In accordance with General Condition Number 23, "Regional and Case-by-Case Conditions," the following Regional Conditions, as added by the Division Engineer, must be met in order for an authorization by any Nationwide to be valid: 1. For coastal watersheds from the southern reach of the Santa Monica Mountains in Los Angeles County to the San Luis Obispo County/Monterey County boundary, all road crossings must employ a bridge crossing design that ensures passage and/or spawning of steelhead (Oncorhynchus mykiss) is not hindered in any way. ln these areas, bridge designs that span the stream or river, including designs for pier-or pile-supported spans, or designs based on use of a bottomless arch culvert simulating the natural stream bed (i.e., substrate and streamflow conditions in the culvert are similar to undisturbed stream bed channel conditions) shall be employed unless it can be demonstrated the stream or river does not support resources conducive to the recovery of federally listed anadromous salmonids, including migration of adults and smolts, or rearing and spawning. This proposal also excludes approach embankments into the channel unless they are determined to have no detectable effect on steelhead. 2.

PROJECT DESCRIPTION/ ENVIRONMENTAL SETTING AND SURROUNDING LAND USES: See attached project description September 2007 4926-01 El Camino Real Widening Project EIA Form -Part II Project Description-El Camino Real Widening Project This section provides a description of the proposed project, the environmental effects of which are evaluated in the Discussion of Environmental Evaluation Section of this MND. The site description and project location are described in this section, followed by a description of project characteristics and a summary of the discretionary approvals that would be required. Site Description and Background The El Camino Road Widening project site is located in the northeastern part of the City of Carlsbad, California (Figure 1, Regional Map and Figure 2, Vicinity Map). As shown in Figures 2 and 3 the project's Area of Potential Effects (APE) extends from Tamarack Avenue, at approximately 70 feet above mean sea level (AMSL) in the southeast to Chestnut A venue, at an elevation of approximately 300 feet AMSL in the north. The APE is the area within which potential environmental impacts would occur, including construction-related and potential long term effects. The APE is approximately 18.5 acres for the El Camino Real Widening Project. The length of the APE :from Tamarack Avenue to Chestnut Avenue is approximately 4,600 linear feet or 0.87 miles. El Camino Real was built in a small canyon between northwest-southeast trending hills. The site is located on the U.S. Geological Service (USGS) 7.5 minute San Luis Rey quadrangle map in projected sections 4, 5 and 9; Township 12 South, Range 3 West (Figure A 2). An isolated, intermittent blue line stream was mapped in the project area, running parallel W and east of El Camino Real and dissipating into the valley extending southward toward Agua Hedionda Creek into which Tamarack A venue was constructed. The APE lies within the Habitat Management Plan for Natural Communities in the City of Carlsbad (HMP) plan area. El Camino Real is classified as a Prime Arterial in the City's Circulation Plan. It is a four-lane divided roadway between Chestnut and Tamarack A venues. The posted speed limit is 55 miles per hour within the APE and a bus stop and bike lanes are provided. Curbside parking is prohibited .. Existing traffic volume along the project site is approximately 24,360 average daily traffic (LLG 2006). Residential development surrounds the APE. Aboveground utilities exist along the length of both sides of the APE and a concrete-lined drainage ditch occurs along a portion of the project's west side. There is a small grove of mature eucalyptus trees located at the northwest comer of the APE, and south of the eucalyptus grove, there are several private residences with a gravel- covered driveway connecting El Camino Real to asphalt-paved private driveways. The portion of the APE located south of the residences has steep slopes overlain by a relatively level · vegetated area.

I FIGURE I Regional Map - L L - El Camino Real Widening Project . MND I Fm3unE I APE with Aerial Photograph • EIA Form -Part II A drainage ditch is located along the southern half of the east side of the APE. A cleared area is maintained along the eastern edge of the drainage. A paved sidewalk runs along the east side of the APE, most of which is open space with a mix of native and non-native grasses and low shrubs. The northern portion of the east side of the project is a vertical cutbank. Project Description The City of Carlsbad (City) proposes to improve the section of EI Camino Real from Tamarack Avenue north to Chestnut Avenue. EI Camino Real is a major north/south roadway serving as a vital parallel circulation element to Interstate 5 (I-5) for the Cities of Encinitas, Carlsbad and Oceanside. As various developments including subdivisions have . occurred in the project vicinity, developers have been required to widen EI Camino Real to full prime arterial standards. This section of roadway, from Tamarack Avenue to Chestnut Avenue, is one of the few remaining sections of El Camino Real that has not been widened to its full width of 6 travel lanes with 3 northbound and 3 southbound lanes. The proposed roadway improvements would result in a total width of 126 feet including: • 8-foot-wide bike lanes on both sides of the roadway • three southbound lanes, 12 feet wide each • three northbound lanes, 12 feet wide each • an 18-foot-wide landscaped median island • 5 ½ -foot-wide sidewalks on both sides of the roadway • 4 ½-foot-wide native planted area (including a native planted swale) on both sides of the roadway In the middle section of the roadway, the roadway would transition between the previously discussed typical section to a modified width of 116 feet including: • a 6 ½-foot-wide bike lane on the west side of the roadway • a 5-foot-wide bike lane on the east side • three southbound lanes, 12 feet wide each • a 14-foot-wide landscaped median island • three northbound lanes, 11 ½ feet wide each • 5. ½-foot-wide sidewalks on both sides of the roadway • 4 ½-foot-wide native planted area (including a native planted swale) on both sides of the roadway The project proposes to keep the existing vertical profile of the road, and construction is anticipated to extend approximately 9 months. The project's site plan and APE is displayed in Figure 4.

L - EIA Fonn -Part II Additional characteristics of the proposed project are described below . Intersection Improvements. A traffic study was prepared for the subject project in April 2006 (LLG 2006). The purpose of the report was to analyze the operations at the two intersections along this segment of El Camino Real, for the existing conditions and Year 2030 conditions. The report then identified intersection improvements required to achieve acceptable level of service (i.e., LOS D). These intersection improvements were consequently incorporated into the project design. The 2030 traffic forecast analysis shows that in 2030, the El Camino Real/Tamarack A venue intersection would result in an LOS F during AM and PM peak hours (LLG 2006). As such, the project plans include an additional northbound and southbound thru lane on El Camino Real, and an additional northbound left-tum lane on El Camino Real at its intersection with Tamarack A venue, as shown in Figure 5. This improvement would improve the LOS at this intersection to LOS D or better in the AM peak hour and LOS C in the PM peak hour. Accommodating the additional northbound and southbound lanes, just north of the intersection, would consist primarily of re-stripfag the existing roadway, as sufficient width exists within the current roadway geometry. Associated signal modifications to accommodate the new lane configuration would also be provided. At the El Camino Real/Chestnut Avenue intersection, the project would result in the removal of the existing free right tum islands located at the northwest and southwest comers of the intersectfon and replace these with standard curb returns, pedestrian ramps, and associated signal modifications to accommodate the road widening improvements. These intersection improvements must satisfy Americans with Disabilities Act (ADA) requirements, and therefore, ramps that meet ADA gradient criteria would be constructed near the northwest and southwest comers to connect the improvements to existing sidewalks. Storm Drains. Currently, the roadway in the APE exhibits erosion on the embankment on the east side, pavement cracking and weathering, and bumps/sags. Storm water from the storm drains currently outlets at erosive velocities into a ditch east of the roadway. Storm drains within the APE would be replaced and/or improved, as shown in Figure 4. The project includes the placement of erosion protection in the ditch and/or construction of check dams within the ditch to remedy the issue. The pavement for the roadway would be overlaid with asphalt concrete and/or replaced with a full structural section as necessary. Brow ditches are proposed along the west side of El Camino Real to prevent hillside stormwater from flowing over the sidewalk and onto El Camino Real. The proposed locations are at Stations 513+50 and 536+00. The sizes of the brow ditches would vary from approximately 12-inch minimum depth to 24-inch maximum depth.

Overhead lighting is proposed as part of the project. Lighting would be installed per applicable City standards for wattage and spacing. Each light pole would produce up to 22,000 lumens and would be staggered at 300-foot intervals along both sides of the project section of El Camino Real. Bus Stops. One existing North County Transit District (NCTD) bus stop located on the west side of El Camino Real just south of Chestnut A venue would be relocated as part of the project, although the specific location is in the process of being determined in concert with North County Transit District. It is assumed that the chosen location would not b~ located outside of the project APE. A second bus stop exists along the east side of El Camino Real north ofTainarack A venue. No improvements or alterations to this bus stop are proposed. Utilities. Depending on the availability of funding, the existing overhead power lines along the west and east sides of El Camino Real may be undergrounded as part of the project. Should funding be available at the time of construction, possibly as a joint cost sharing effort with SDG&E, the City would underground these electrical utilities. If a funding source for undergrounding is not located, the existing power poles along the west side, north of APN 207- 090-20, Station 526+00, are proposed to be relocated 5 to 10 feet to the west. The relocation or undergrounding of these poles is necessary to accommodate the proposed street widening. Grading. Minor grading would occur along the west side of El Camino Real to accommodate construction of proposed retaining walls, which are described below. Additional· grading behind and at the top of the retaining walls would occur to construct brow ditches and drainage facilities. The proposed grading at the top of the walls would be contoured to a 1.5: I or 2: 1 inclination to blend into the natural look of the existing terrain. The proposed grading would range from 5 to 8 feet in height above the top of wall. Both minor grading and major grading would occur on the east side of the project. Minor re- grading is required at two locations (at approximately Station 512+50 and Station 517+00) to stabilize the existing fill slope adjacent to the east edge of the roadway, which also represents the west edge of the existing drainage channel. These two locations are situated approximately in the middle third of the APE and represent distressed areas where slope failure (Station 512+50) and sloughing (Station 517+00) have occurred. The existing slope height at these areas varies from 5 feet or less to approximately 15 feet with the height generally increasing toward the north. Both of these areas would be over-excavated and reconstructed with reinforced earth or equal methods in accordance with the geotechnical report for the project to stabilize the slope and re-establish the initial slope inclination. Major grading is proposed along the northern segment of the east side of El Camino Real, predominantly across Assessor Parcel Numbers 167-230-24 and 167-230-25. Slope heights September 2007 4926-01 El Camino Real Widening Project 10 L I L L L EIA Form -Part II would range from 30 to 50 feet with the height increasing toward the south. The proposed grading will be contoured to a L5:1 or variable slope inclination and be graded in such a fashion as to replace the in-kind driveway access to the property. Retaining Walls. Retaining walls are proposed on the west side of El Camino Real in the approximate midpoint of the APE. A portion of the proposed retaining walls would be located outside of the project ROW, therefore, property acquisition of 6,946 square feet (0.16 acre) would be required on Czajkowski property (within parcel numbers 207-180-08, -09, -10, and - 12), which is located approximately 2000 feet south of the El Camino Real/Chestnut A venue intersection. The height of the retaining walls would vary from 6 feet to a maximum of 15 feet high. The specific wall types would be Caltrans cast-in-place concrete or masonry block cantilever with fascia for walls less than 10 feet in height. These have a concrete spread footing and a vertical retaining face. For walls over 10 feet in height, a tieback wall type would be implemented. This type of retaining wall is an anchored wall system that relies on steel bars grouted into the retained slope and a reinforced facing. The anchors are prestressed to provide an active clamping force. The facing is typically constructed with reinforced shotcrete or cast-in-place concrete, and is constructed with a "top-down" approach that does not require substantial excavation behind the wall face. The retaining walls are proposed to be built with a boulderscape architectural treatment and landscaping screening. Drainage systems would be included behind the walls to allow proper drainage of the adjacent hillside. Landscape Concept Plan. A Landscape Concept Plan has been prepared as part of the project to provide a transition between the ornamental landscape and natural landscape on either side of the project reach of El Camino Real. The Landscape Concept Plan takes into account the City's El Camino Real Corridor Development Standards by incorporating a median landscape treatment that continues adjacent median designs. The Landscape Concept Plan is displayed in Figures 6a through 6d. The specific objectives of the design include low water use, minimization of fire hazards, minimization of visual impacts of the proposed retaining walJs, and stabilization of disturbed slopes. Staging Areas. Staging areas for temporarily storing construction equipment would be identified during final design of the project, and would be located within previously paved areas within the APE.

EIA Fonn -Part II ENVIRONMENTAL IMPACTS STATE CEQA GUIDELINES, Chapter 3, Article 5, Section 15063 requires that the City conduct an Envirorunental Impact Assessment to determine if a project may have a significant effect on the environment. The Environmental Impact Assessment appears in the following pages in the form of a checklist. This checklist identifies any physical, biological and human factors that might be impacted by the proposed project and provides the City with information to use as the basis for deciding whether to prepare an Environmental Impact Report (EIR), Negative Declaration, or to rely on a previously approved EIR or Negative Declaration. • A brief explanation is required for all answers except "No Impact" answers that are adequately supported by an information source cited in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved. A "No Impact" answer should be explained when there is no source document to refer to, or it is based on project-specific factors as well as general standards. • "Less Than Significant hnpact" applies where there is supporting evidence that the potential impact is not significantly adverse, and the impact does not exceed adopted general standards and policies. • "Potentially Significant Unless Mitigation Incorporated'.'. applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Than Significant Impact." The developer (in this case, the City of Carlsbad, since the project is a public works project) must agree to the mitigation, and the City must · describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level. • "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significantly adverse. • Based on an "EIA-Part II", if a proposed project could have a potentially significant adverse effect on the erivironment, but all potentially significant adverse effects (a) have been analyzed adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigated Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed project, and none of the circumstances requiring a supplement to or supplemental EIR are present and all the mitigation measures required by the prior environmental document have been incorporated into this project, then no additional environmental document is required.

In this case, the appropriate "Potentially Significant Iinpact Unless Mitigation Incorporated" may be checked and a Mitigated Negative Declaration may be prepared. • An EIR must be prepared if "Potentially Significant Impact" is checked, and including but not limited to the following circumstances: (1) the potentially significant adverse effect has not been discussed or mitigated in an earlier EIR pursuant to applicable standards, and the City does not agree to mitigation measures that reduce the adverse impact to less than significant; (2) a "Statement of Overriding Considerations" for the significant adverse impact has not been made pursuant to an earlier EIR; (3) proposed mitigation measures do not reduce the adverse impact to less than significant; or (4) through the EIA-Part II analysis it is not possible to determine the level of significance for a potentially adverse effect, or detennine the effectiveness of a mitigation measure in reducing a potentially significant effect to below a level of significance. A discussion of potential impacts and the proposed mitigation measures appears at the end of the form under DISCUSSION OF ENVIRONMENTAL EVALUATION. Particular attention should be given to discussing mitigation for impacts, which would otherwise be determined significant .

September 2007 4926-01 El Camino Real Widening Project 28 I. a) · DISCUSSION OF ENVIRONMENTAL EVALUATION AESTHETICS-Would the project: Have a substantial adverse effect on a scenic vista? EIA Form -Part II No Impact. In I 988, the City prepared Scenic Corridor Guidelines to identify roadways and transportation routes within the City to be designated as scenic corridors, and to suggest methods to preserve and enhance the character of those corridors (City of Carlsbad 1994). According to the City's Circulation Element ( 1994), Carlsbad has adopted four categories of scenic corridors. Transportation routes with potential corridor status are identified below; however, currently, El Camino Real is the only designated roadway within the City for which a set of development standards have been adopted. Community Theme Corridors. These connect Carlsbad with adjacent municipalities and present the City of Carlsbad to persons entering andl passing thought the community. Community Theme Corridors include El Camino Real, Carlsbad Boulevard, Palomar Airport Road, La Costa A venue, and Melrose Drive. Community Scenic Corridors. These roadways interconnect major subareas of the present and - planned Carlsbad community. They include College Boulevard, Cannon Road, Carlsbad Village - Drive, Faraday Avenue, I-5, La Costa Avenue, Olivenhain Road/Rancho Santa Fe Road, and Poinsettia Lane/Carrillo Way. Natural Open Space and Recreation Con·idors. These offer spectacular views of waterscapes, landforms, wildlife, and the Pacific Ocean, and include Adams Street/Park Drive, Batiquitos Drive, and Jefferson Street (the portion adjacent to the Buena Vista Lagoon). Railroad Corridor. This corridor presents the City to people passing through by rail, on the Atchison, Topeka, & Santa Fe (AT&SF) Railroad. While El Camino Real has been designated as a Community Theme Corridor by the City, there are no officially designated scenic vistas identified in the City's General Plan (1994), and no scenic vistas are afforded while driving along the project segment of El Camino Real. Therefore, no impacts to a scenic vista would result. b) Substantially damage scenic resources, including but not limited to, trees, rock outcroppings, and historic buildint~s within a State scenic highway? Less Than Significant Impact. As described above in response a), there are no officially - designated state highways located within the project vicinity, but the City has designated El September 2007 4926-01 El Camino Real Widening Project 29 EIA Form -Part II Camino Real under its Scenic Corridor Overlay Zone. El Camino Real is also listed under the Community Theme Corridor category. The proposed project is not located within a section of El Camino Real that is adjacent to the adjoining jurisdictional areas to the north or south. The Open Space and Conservation Element's Special Resource Protection Implementing Policies and Action Programs C4 states that the City shall "Designate for preservation as open space those areas that provide unique visual amenities and define the urban form as contained in the Open Space and Conservation Resource Management Plan. These areas shall include agriculture, hillsides, ridges, valleys, canyons, beaches, lagoons, lakes and other unique resources that provide visual and physical relief to the cityscape by creating natural contrasts to the built-up manmade scene" (City of Carlsbad 1994). A small portion of land located to the west of El Camino Real is designated as Open Space in the City's General Plan. No designated Special Resource Protection areas are located in the vicinity of the project site. Unique resources --as defined in policy C4, such as hillsides and agriculture, are located near the proposed project site. The project site is also subject to the El Camino Real Corridor Development Standards (1984). The intent of these standards is to maintain and enhance the appearance of the El Camino Real roadway area, and reflect the existence of certain identified characteristics which the City considers worthy of preservation (City of Carlsbad 1984). The project site is located in Area 2 of the Standards. The project involves improvements and widening of this segment of El Camino Real, and many of the standards discussed in the regulations pertain to such details as signage, setback from roadway, and building height, which do not apply to the proposed project. The project would incorporate other design features such as sidewalks and would not modify the existing identified design theme of suburban residential. Overall, the project would not conflict with the El Camino Real Corridor Development Standards, and impacts would be less than significant. As described in the project description, a retaining wall would be required along the west side of El Camino Real in the approximate midpoint of the APE, as shown in the visual simulations provided in Figures 7 and 8. The height of the retaining walls would vary between 6 to 15 feet in height, and would be constructed with a naturalized boulderscape architectural treatment and landscaping screening. A native hydroseed mix would be applied along the western side of the proposed retaining wall, in addition to native shrubs to be planted on both the western and eastern sides of the proposed wall. Vines and native groundcover would also be provided on the eastern side of the proposed wall, the section of the wall visible to passing travelers. The retaining walls would introduce a manmade feature to an otherwise natural hillside, but because travelers are typically driving at relatively high speeds (55 mph), views would not last more than 5 seconds. Also, due to the proposed boulderscape treatment, the retaining wall would be constructed to look similar to existing conditions, and over time, the proposed landscaping would September 2007 4926-01 El Camino Real Widening Project 30 r r [ . \ Existing Photo 1: View looking south at existing El Camino Real roadway and adjacent hillside, approximately 1,200 feet south of the intersection of El Camino ReaJ and Chestnut Avenue.

No other sceruc resources such as trees, rock outcroppings, or historic buildings would be affected. If the existing overhead power lines along the west side are undergrounded, thereby removing the poles and wires from existing views, a beneficial impact would result. A planted median and proposed parkways on both sides of the roadway (including sidewalks and 4 1/2 feet of native planted area) would also result in beneficial visual effects to the corridor. For these reasons, visual impacts would be less than significant. c) Substantially degrade the existing visual character or quality of the site and its surroundings? Less than Significant Impact. The proposed project entails the widening of an existing roadway. The additional lanes and project components along this stretch of El Camino Real would not alter adjacent land uses. As such, the project would not substantially degrade the existing visual character or quality of the project site or its surroundings, and impacts would be less than significant. d) Create a new source of substantial light and glare, which would adversely affect day or nighttime views in the area? Less Than Significant Impact. Lighting is currently provided along this stretch of El Camino Real. The project would replace the existing lighting to the ultimate width of El Camino Real. The lighting would be installed per applicable City standards for wattage and spacing which permits each light post to be staggered at 300-foot intervals along both sides of El Camino Real and produce up to 22,000 lumens per light post. Therefore the amount of light and glare would not substantially differ from existing conditions, and impacts would be less than significant. II. AGRICULTURAL RESOURCES-Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? No Impact. As stated in the Open Space and Conservation Element of the City's General Plan, it is the City's intention to support and utilize all measures available to secure agricultural land uses for as long as possible prior to development, and to promote the long-te~ economic viability of agricultural uses. There are only a limited number of areas within the City that are considered to possess important farmlands as defined by the Califorrua Department of Conservation. The City consists mainly of Urban and Built-Up Land along the western, September 2007 4926-01 El Camino Real Widening Project 33 -,- L I \,.. L EIA Form -Part II southern, and northwestern portions of the City, with large areas of Other Land interspersed throughout the eastern and central portions (City of Carlsbad 1994). According to the State of California Department of Conservation (DOC) San Diego County Important Farm.land 1998 Map, the proposed project site and the areas immediately to the north, east, south and west are designated as Urban and Built Up Land, with areas to the southeast of the El Camino R~al/famarack Road interchange designated as Other Land. (DOC 1998). No Prime, Unique or Farmland of Statewide Importance would be converted as ·a result of implementing the proposed project, and no impacts would result. b) Conflict with existing zoning for agricultural use, or a Wil1iamson Act contract? No Impact. According to the City of Carlsbad's Zoning Map dated July 25, 2006, the project site is zoned as El Camino Real Corridor Overlay. It should also be noted that the designated zoning for the surrounding land uses includes Planned Community (P-C) for the southern half and One-Family Residential (R-1) in the northern half, with a small portion of land to the northwest zoned as Residential Density -Multiple (RD-M). No agricultural· uses have been zoned for land surrounding the project site; therefore the proposed project would not conflict with existing zoning for agricultural uses or any Williamson Act contracts in the City, and no impacts would result. c) Involve other changes in the existing environment, which, due to their location or nature, could result in conversion of Farmland to non-agricultural use? No Impact. As described in responses a) and b) above, the proposed widening improvements to El Camino Real would not result in the conversion of farmland at the proposed project site or surrounding areas. No other changes to the existing environment would result in conversion of farmland to non-agricultural use, and no impact would result from implementing the proposed project. III. AIR QUALITY-Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? No Impact. The project site is located in the San Diego Air Basin which is a federal and state non-attainment area for ozone (03), and a state non-attainment area for particulate matter less than or equal to 10 microns in diam_eter (PM10). The periodic violations of national Ambient Air Quality Standards (AAQS) :in the San Diego Air Basin (SDAB), particularly for ozone in inland foothill areas, requires that a plan be developed outlining the pollution controls that will be - - undertaken to improve air quality. In San Diego County, this attainment planning process is - September 2007 4926-01 El Camino Real Widening Project 34 -- .,.. - . ' ' L EIA Fonn -Part II embodied in the Regional Air Quality Strategies (RAQS) developed jointly by the Air Pollution Control District (APCD) and the San Diego Association of Governments (SAND AG). A plan to meet the federal standard for ozone was developed in 1994 during the process of updating the 1991 state-mandated plan. This local plan was combined with plans from all other California non-attainment areas having serious ozone problems and used to create the California State Implementation Plan (SIP). The SIP was adopted by the Air Resources Board (ARB) after public hearings on November 9th through 10th in 1994, and was forwarded to the Environmental Protection Agency (EPA) for approval. After considerable analysis and debate, particularly regarding airsheds with the worst smog problems, EPA approved the SIP in mid-1996. The proposed project relates to the SIP and/or RAQS through the land use and growth assumptions that are incorporated into the air quality planning document. These growth assumptions are based on each city's and the County's general plan. If a proposed project is consistent with its applicable General Plan, then the project presumably has been anticipated with the ·regional air quality planning process. Such consistency would ensure that the project would not have an adverse regional air quality impact. Section 15125(B) of the State of California Environment Quality Act (CEQA) Guidelines contains specific reference to the need to evaluate any inconsistencies between the proposed project and the applicable air quality management plan. Transportation Control Measures {TCMs) are part of the RAQS. The RAQS and TCM plan set forth the steps needed to accomplish attainment of state and federal ambient air quality standards. The California Air Resources Board provides criteria for determining whether a project conforms with the RAQS which incJude the following: • Is a regional air quality plan being implemented in the project area? • Is the project consistent with the growth assumptions in the regional air quality plan? The project site is located in the San Diego Air Basin, and as such, is located in an area where a RAQS is being implemented. The project is consistent with the growth assumptions of the City's General Plan and the RAQS. Therefore, the project is consistent with the regional air quality plan and will in no way conflict or obstruct implementation of the regional plan, and no impact would result. September 2007 4926-01 El Camino Real Widening Project 35 EIA Fann -Part II b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Less Than Significant Impact. The closest air quality monitoring station to the project site is in Camp Pendleton. Data available for this monitoring ,site through April, 2002 indicate that the most recent air quality violations recorded were for the state one· hour standard for ozone ( one day in both 2000 and 2001) and one day in 2001 for the federal 8-hour average for ozone and one day for the 24-hour state standard for suspended particulates in 1996. No violations of any other air quality standards have been recorded recently. The project would involve minimal short-tenn emissions associated with grading and construction. The principal source of emissions would be fugitive dust from earth moving activities, storage piles, and vehicle travel on unpaved and paved surlaces. Such emissions would be minimized through standard construction measures such as the use of properly tuned equipment and watering the site for dust "7 control. Therefore, impacts from construction related emissions would be less than significant. Operations of the proposed project would not generate substantial traffic, increase the number of ve~cles operating in the cold start mode, or worsen congestion, since it would widen the existing roadway per General Plan standards. Therefore, pollutant emission would likely be the same or '-less than without the proposed project. Long-term impacts would be less than significant overall. I ' 7 I ' ' I '-- c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? Less Than Significant Impact. The Air Basin is currently in a non-attainment zone for ozone and suspended fine particulates. The proposed project would represent a contribution to a cumulatively considerable potential net increase in emissions throughout the air basin. As described above, however, construction emissions associated with the proposed project would be short-term, and long-term operational air quality emissions would be essentially the same as the baseline emissions. Therefore, according to the CEQA Guidelines Section 15130, the proposed project's contribution to the cumulative impact is considered de minimus, and impacts would be less than significant. d) Expose sensitive receptors to substantial pollutant concentrations? Less Than Significant Impact. Residences are located along both the eastern and western sides of the proposed project site. No other sensitive receptors (e.g. schools or hospitals) are located in the vicinity of the proposed project. As noted above, the proposed project would not result in substantial pollutant emissions or concentrations. Therefore, impacts to sensitive receptors would be less than significant. September 2007 4926-01 El Camino Real Widening Project 36 - --i -- EIA Form -Part II e) Create objectionable odors affecting a substantial number of people? Less Than Significant Impact. The construction of the proposed project could generate fumes from the operation of construction equipment and from asphalt paving and grading, which may be considered objectionable by some people. Such exposures would be short-term and/or transient since they would occur during the construction phase only, and would not reach a level of significance. IV. BIOLOGICAL RESOURCES -Would the project: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by California Department of Fish and Game or U.S. Fish and Wildlife Service? Potentially Significant Impact Unless Mitigation Incorporated. A Biological Resources Technical Report (Dudek' 2007) was prepared for the project. Regarding sensitive habitats, direct permanent impacts to vegetation communities include all areas within the proposed project APE, as shown in Figures 9 and 9a through 9d. As shown in the figures, a 28.9-acre study area was surveyed, which included the 18.5-acre APE. Implementation of the proposed project would potentially result in the direct permanent loss of the vegetation community and non-natural land cover acreages shown in Table I below, including the acreage of each within the Coastal Zone.

MND I FIGURE I Biological Resources Map with APE Limits · SD · -- EIA Form -Part II Direct pennanent impacts to vegetation communities and land covers listed as HMP habitats in the City HMP would be considered significant. Direct impacts to 1.31 acre of coastal sage scrub (inc1uding disturbed), 0.02 acre of disturbed native grassland, 0.11 acre of non-native grassland, 0.40 acre of southern willow scrub (including disturbed), 0.33 acre eucalyptus woodlands, and 2.60 acres disturbed land, all vegetation communities and land covers listed as HMP habitats in the City HMP, are considered significant. Refer to mitigation measures listed below that would reduce impacts to a level below significance .. Regarding sensitive wildlife species, the project has the potential to impact 0. 73 acre of potential Cooper's hawk nesting habitat (southern willow scrub and eucalyptus); 1.44 acres of Dulzura pocket mouse and northwestern San Diego pocket mouse habitat ( coastal sage scrub and grasslands) .. Potential impacts to nesting Cooper's hawk, Dulzura California pocket mouse and northwestern San Diego pocket mouse, if present, would be considered significant. Refer to mitigation measures listed below that would reduce impacts to a level below significance .. Surveys for monarch butterfly roosting sites were negative, and therefore no impacts would occur to this species. Potential indirect impacts to sensitive plant and wildlife species include construction-related edge effects such as dust which could disrupt plant vitality in the short-tenn or construction- related soil erosion and water runoff. Edge effects generally would only occur along the interface between the project impact area and adjacent sensitive habitat, including coastal sage scrub, native grassland, non-native grassland, southern willow scrub, and jurisdictional stream channels. However, standard construction BMPs and construction-related minimization measures to control dust, erosion, and runoff will be implemented and will ameliorate these effects (refer to Section VIII, Hydrology and Water Quality, response a). Therefore, significant indirect impacts to sensitive plant and wildlife species would be avoided through these measures. Regarding sensitive plant species, the Biological Resources Technical Report concludes that no sensitive plant species occur in the APE, and no direct impacts to sensitive plant species would result. Mitigation Measures for Sensitive Vegetation Communities BI0-1:Prior to grading, significant direct impacts to sensitive vegetation communities shall be mitigated in the amounts shown in the discussion below. Mitigation shall be implemented to the satisfaction of the City Planning Department. The mitigation ratios are also displayed in Table 2. .. September 2007 The loss of 0.02 acre (715 square feet) of disturbed native grassland within the Coastal Zone (CZ) shall be mitigated at a ratio of 3: 1, including 1: I habitat creation. Because only 0.02 acre of native grassland creation is required, this 4926-01 El Camino Real Widening Project 43 • • • Coastal sage scrub includin disturbed EIA Form -Part II shall be incorporated (as container plantings) into the coastal sage scrub habitat creation discussed below. The loss of 0.35 acre of CZ coastal sage scrub shall be mitigated at a 2: 1 ratio including habitat creation at a 1: 1 ratio. A total of 0.37 acre of coastal sage scrub habitat shall be created within the CZ, including a sufficient quantity of container plants as native grasses equivalent to the creation of 0.02 acre of native grassland. The remaining I : 1 mitigation for impacts to CZ coastal sage scrub, together with 1: I mitigation for non-CZ coastal sage scrub impacts, shall be achieved through preservation of 1.31 acres of coastal sage scrub habitat by use of mitigation credit in the City of Carlsbad's Lake Calavera Mitigation Bank .. Loss of 0.11 acre of non-native grassland shall be mitigated by preservation of 0.06 acre of non-native grassland ( or superior habitat) by use of mitigation credit in the City of Carlsbad's Lake Calavera Mitigation Bank. Loss of 0.33 acre of eucalyptus woodland and 2.60 acres of disturbed lands shall be mitigated by 0.03 acre and 0.26 acre habitat preservation, respectively, at the Lake Calavera Mitigation Bank, and may be out-of-kind.

Mitigation measures for impacts to southern willow scrub are discussed below under response b ). Mitigation Measures for Sensitive Wildlife Species BI0-2:Prior to grading, significant direct impacts to sensitive wildlife species shall be mitigated to the satisfaction of the City Planning Department. The following mitigation measures would avoid impacts to Cooper's hawk, other raptors and other migratory bird species nests protected under the Migratory Bird Treaty Act: September 2007 4926-01 El Camino Real Widening Project 44 - - - - - • • EIA Form -Part JI The City's construction contractor shall conduct vegetation clearing outside of the January through September bird breeding season; or A qualified biologist shall conduct a focused survey for bird nests not more than 72 hours prior to commencement of vegetation clearing activities. If active nests are found, the City's construction contractor shall cease construction within an appropriate buffer zone of 50 to 300 feet, as determined by the project biologist, around the nest site until juveniles have fledged and the nesting cycle is complete. Impacts to Cooper's hawk, Dulzura California pocket mouse, and northwestern -San Diego pocket mouse shall be mitigated through creation and/or preservation of riparian scrub and eucalyptus woodland (Cooper's hawk), and coastal sage scrub and grassland (pocket mice) habitats discussed under BIO-1 above. [Note: the loss of approximately 0. 7 acre of potential Cooper's hawk nesting habitat (eucalyptus and riparian scrub) shall be mitigated through creation or preservation of 1.20 acres of riparian habitat and 0.03 acre of eucalyptus woodland.] The location of the riparian scrub would be determined as part of the CDFG 1602 permit process. b) Have a substantial adverse effect on any riparian, aquatic or wetland habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by California Department of Fish and Game or U.S. Fish and Wildlife Service? Potentially Significant Unless Mitigation Incorporated. Direct permanent impacts to 0.19 acre of waters, including wetlands, under the jurisdiction of ACOE, CDFG, and RWQCB, and an additional 0.33 acre of riparian vegetation under the jurisdiction of CDFG only (for a total CDFG-jurisdictional area of 0.52 acre) are considered significant (Dudek 2007). Table 3 below shows the breakdown of waters/wetlands impacts and the acreage of each. Potential indirect impacts to jurisdictional stream channels and sensitive vegetation communities (i.e., southern willow scrub, coastal sage scrub, native grassland, non-native ~assland) include construction- related edge effects such as dust which could disrupt plant vitality in the short-term or construction-related soil erosion and water runoff. Edge effects generally would only occur along the interface between the APE (i.e., where construction and/or grading or other physical impacts would occur) and adjacent sensitive habitat, including jurisdictional stream channels, southern willow scrub, coastal sage scrub, native grassland and non-native grassland. However, standard construction BMPs and construction-related minimization measures to control dust, erosion, and runoff will be implemented and will ameliorate these effects as stated under Section VIII, Hydrology and Water Quality response a). Therefore, significant indirect impacts to jurisdictional areas and other sensitive vegetation communities would be reduced to less than significant levels through these measures.

Mitigation Measures for Jurisdictional Waters BI0-3 Prior to grading, significant direct impacts to jurisdictional waters and riparian habitats shall be mitigated to the satisfaction of the City Planning Department. The following mitigation measures would reduce impacts to a level below significance: • Mitigation for impacts to jurisdictional waters and riparian habitats shall include 1: 1 creation in accordance with the "no net loss" wetlands policy in the Carlsbad HMP. Impacts to 0.40 acre of southern willow scrub shall be mitigated at a ratio of 3: 1, consisting of creation of 0.40 acre (1: 1) of southern willow scrub and use of 0.80 acre (2:1) of mitigation credit in the City of Carlsbad's Lake Calavera Mitigation Bank. • Impacts to 0.12 acre of ephemeral and intermittent stream channels shall be mitigated through creation of 0.12 acre of stream channel ( or superior) habitat. • A combined total of 0.52 acre of wetland habitat and jurisdictional stream channels shall be created in partial mitigation for wetland impacts. • A Clean Water Act (CWA) Section 404 Nationwide Permit shall be required from the ACOE for project impacts to 0.19 acre of A COE-jurisdictional waters. • A CWA Section 401 permit from RWQCB shall be required for impacts to 0.19 acre of waters under their jurisdiction. • A CDFG Section 1602 Streambed Alteration Agreement shall be required from CDFG for impacts to 0.52 acre of jurisdictional waters and riparian vegetation. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Potentially Significant Unless Mitigation Incorporated. Refer to response b) above. September 2007 4926-01 El Camino Real Widening Project 46 - - d) EIA Form -Part II Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Less Than Significant Impact. The City of Carlsbad specifically identifies habitat linkages as part of the Habitat Management Plan (HMP), with Linkages consisting of conserved habitat that provides a connection between the HMP core areas and other natural habitat areas. The vicinity of the proposed project is not identified as a Linkage in the HMP and is not located within a habitat corridor. The project would involve widening of an existing roadway. As such, impacts would be less than significant. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? No Impact. The project would not conflict with the Carlsbad HMP, or any other local policies or ordinances protecting biological resources. Also refer to response t) below. No impacts would result. f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? No Impact. The proposed project site is located within the City of Carlsbad HMP and is part of the El Camino Real Widening -South Chestnut to South Alga Street project, which is covered by the proposed City Lands mitigation bank. (Note: subsequent to publication of the HMP, the "South Alga" street name was changed to A viara Parkway to the west of El Camino Real, and Alga Road east of El Camino Real.) The proposed project would comply with the HMP guidelines and requirements, and therefore, the project is consistent with the Carlsbad HMP. No impacts would result. V. CULTURAL RESOURCES-Would the project: a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5? · No Impact. A Cultural Resources Technical Report was conducted for the proposed project in 2006 (ASM 2006). A review of historic maps of the project vicinity in addition to a database search of the National Register of Historic Places, California Register of Historic Resources, California State Landmarks, California Points of Historic Interest and other historic property lists were conducted and did not reveal any historic structures within the project vicinity (ASM 2006). Therefore, no impacts to historical resources would result. September 2007 4926-01 El Camino Real Widening Project 47 b) EIA Form-Part II Cause a substantial adverse change in the significance of an archeological resource pursuant to §15064.5? Potentially Significant Impact Unless Mitigation_ Incorporated. According to the Cultural Resources Technical Report, two prehistoric habitation sites have previously been recorded within a one-mile radius of the project site. No additional archeological resources were identified during the site reconnaissance survey. Because a number of large habitation sites are located within a one-mile radius of the project, the known presence of large archaeological sites in the vicinity, and due to the fact that during surveys, heavy leaf litter was present which limited visibility, potentially significant impacts to archaeological resources could result. Accordingly, implementation of the following mitigation measures during project grading and construction activities would reduce potential impacts to archeological resources to less than. significant levels. CULT-1: Archeological monitoring shall occur during all earthmoving activities, to the satisfaction of the City of Carlsbad Planning Department. The mitigation monitoring program shall consist of the following measures: Prior to Preconstruction (Precon) Meeting 1. Planning Department Plan Check a.

September 2007 4926-01 El Camino Real Widening Project 50 - - - - b. EIA Form -Part II material ·is identified as to species; and that specialty studies are completed, as applicable. Curation of artifacts associated with the survey, testing and/or data recovery for this project shall be completed in consultation with the CP and the Native American representative, as applicable. 2. Final Results Reports (Archaeological Monitoring and/or Research Design and Data Recovery Program) 3. a. Within three months following the completion of monitoring, two copies of the Final Results Report (even if negative) and/or evaluation report, if applicable, which describes the results, analysis, and conclusions of the Archaeological Monitoring Program (with appropriate graphics) shall be submitted to the CP for b. approval. For significant archaeological resources encountered during monitoring, the Research Design and Data Recovery Program shall be included as part of the Final Results Report. Recording Sites with State of California Department of Park and Recreation The Archaeologist shall be responsible for recording (on the appropriate State of California Department of Park and Recreation forms-DPR 523 A/B) any significant or potentially significant resources encountered during the Archaeological Monitoring Program in accordance with the City's Historical Resources Guidelines, and submittal of such forms to the South Coastal Information Center with the Final Results Report. c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Less Than Significant Impact. No previous paleontological resources have been recorded within one mile of the project site. During the site survey, one piece of marine shell and one fragment of a large mammal bone were identified in the project vicinity (ASM 2006). However, a close inspection of extensive excavations in the area where these resources were found did not reveal any further potential remains, and impacts to paleontological resources would be less than significant. d) Disturb any human remains, including those interred outside of formal cemeteries? No Iinpact. No human remains were identified in the Cultural Resources Technical Report prepared for the proposed project, and the report did not indicate the potential for remains to be encountered during construction activities (ASM 2006). As a result, no impacts are anticipated. September 2007 4926-01 El Camino Real Widening Project 51 VI. EIA Fonn -Part II GEOLOGY AND SOILS-Would the project: a) Expose people or structures to potiential substantial adverse effects, including the risk of loss, injury or death involving: i) Rupture of a known earth1ciuake fault, as delineated on the most recent Alquist-Priolo Earthquakti Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Ref er to Division of Mines and Geology Special Publication 42. Less Than Significant Impact. A Geotechnical Engineering Investigation Report was prepared in 2006 for the proposed project (Testing Engineers 2006). According to the report, the proposed project is not located within any Earthquake Fault Zone delineated by the State of California for the hazard of fault surface rupture (Testing Engineers 2006). ii) Strong seismic ground shaking? Less Than Significant Impact. Southern California, including the proposed project site is located in a seismically active area. The closest known active fault to the project site is the Rose Canyon fault zone, which is located approximately 6 miles from the site (Testing Engineers 2006). Other active faults in the area include Elsinore-Julian, Newport-Inglewood, - Coronado Bank and Elsinore-Temecula fault zones, located approximately 23 miles, 6.5 -· miles, 22 miles, and 23 miles from the project site respectively. The most significant seismic hazard at the site is considered to be shaking caused by an earthquake occurring on a nearby or distant active fault (Testing Engineers 2006). The project does not propose to construct any structures, and the proposed widening of the existing roadway would not result in a significant impact such as risk of loss, injury or death due to seismic ground shaking. For these reasons, impacts related to seismic ground shaking would be less than significant. iii) Seismic-related ground failure, including liquefaction? Less Than Significant Impact. Liquefaction is generally known to occur in saturated cohesionless soils at depths shallower than approximately 50 feet. Dynamic settlement due to earthquake shaking can occur in both dry and saturated sands. The project site is mainly underlain by relatively dense Santiago Formation overlain by shallow, fine grained alluvial deposits, without a groundwater table. Ag such, the project site is not considered to be subject to liquefaction. The potential for liquefaction and associated ground deformation occurring beneath the site is considered low (Testing Engineers 2006), and impacts would be less than significant. September 2007 4926-01 El Camino Real Widening Project 52 - - EIA Fonn -Part JI iv) Landslides? Potentially Significant Impacts Unless Mitigation Incorporated. Portions of the adjacent hillsides to the immediate west are proposed to be graded and contoured to a 1.5:1 slope, and held in place with retaining walls, as described in the project description and under Section I, Aesthetics. The grading and construction of retaining walls would be conducted in conformance with the City's standards, but due to their height, scale, and potential for erosion, impacts to people or structures due to landslides 'is considered potentially significant. Impacts would be mitigated with implementation of the following mitigation measure: GE0-1: Prior to grading, the project geotechnical engineer or engineering geologist shall prepare a Final Geotechnical Engineering Investigation Report reflecting the approved project configuration.· This geotechnical study shall, as deemed necessary by the City Engineer and consulting geotechnical engineer, further assess slope stability and slope stability remediation within the proposed widening footprint. The findings and recommendations of the geotechnical assessment shall be incorporated into the final engineering design for the project. b) Result in substantial soil erosion or the loss of topsoil? Potentially Significant Impact Unless Mitigation Incorporated. The project would include the improvement of the existing roadway's pavement and would also include replacement/repair of existing storm drains to the east of the roadway, including the use of rip rap to reduce erosive runoff velocities (refer to Figure 4 for the location of storm drains). In this way, beneficial impacts would result. As a result of grading and project construction, potential erosion and siltation impacts could occur. As described in the Project Description section, grading along the western and eastern slopes of El Camino Real is proposed. Standard BMPs would be employed during grading and construction, such as installation of sediment barriers and gravel/sand bags to prevent offsite sedimentation; dust abatement to minimize fugitive dust; and removal of soil tracked onto paved surfaces. Potentially significant erosion impacts would be mitigated by implementation of the following mitigation measures: GE0-2: All proposed cut and fill slopes identified as susceptible to future erosion and/or soil slippage shall be planted with an erosion retardant ground cover adhering to the following criteria: • The ground cover is effective in preventing surface erosion; • The ground cover is drought resistant; • The ground cover has a relatively low surface mass/weight; September 2007 4926-01 El Camino Real Widening Project 53 • • • Has a fairly deep and extensive root system; Requires minimum maintenance by the owner; and . Has a low irrigation demand . EIA Form -Part II GEQ.:.3: The City Engineer shall be responsible for approving the appropriate erosion control/slope failure control-planting program prior to grading. c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on-or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? Less Than Significant Impact. As mentioned above in response a) iii), the potential for ground deformation occurring beneath the project site is considered low (Testing Engineers 2006). In addition, the site is not located in an area of known ground subsidence due to the withdrawal of subsurface fluids. Therefore the potential for subsidence or collapse occurring at the · site is considered remote (Testing Engineers 2006), and impacts would be less than significant. d) Be located on expansive soils, as defined in Table 18-1-B of the Uniform Building Code (1997), creating substantial risks to life or property? - Less Than Significant Impact. Soils within the project site consist of silty sand, clayey sand - and/or sandy clay (Testing Engineers 2006). According to the Uniform Building· Code Table 18- I-B, these soil types are classified as having a medium to high potential as an expansive soil. Existing soils at the project site would be removed to a depth of at least I foot below existing ground surface and at least 2 feet beyond the road embankment footprint and replaced with fill soils. Therefore, because expansive soils would be replaced, potential impacts would be less than significant. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? No Impact. The project does not propose to provide septic tanks or alternative wastewater disposal systems. Therefore, no impact would result. HAZARDS AND HAZARDOUS MATERIALS-Would the project: VII. a) Create a significant hazard to the ]Public or the environment through the routine transport, use, or disposal of hazardous materials? Less than Significant Impact. Construction activities used for the proposed widening of El Camino Real would not include the use of explosives or acutely hazardous materials. No - hazardous materials would be used with the exception of fuels commonly employed in September 2007 4926-01 El Camino Real Widening Project 54 ··---- I , .... EIA Form -Part II construction vehicles. As such, the project would have no significant impact with regard to creating a potential hazardous condition to the public or the environment through routine transport, use or disposal of hazardous materials. Impacts would be less than significant. b) Create a significant hazard to the public or environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less Than Significant Impact. Relatively small amounts of hazardous substances, such as fossil fuels, lubricants, and solvents would be used onsite for construction and maintenance of the project; however, these materials shall be transported and handled in accordance with all federal, state, and local laws regulating the management and use of hazardous materials. Consequently, use of these materials for their intended purpose would not pose a significant risk to the public or environment, and impacts would be less than significant. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? No Impact. The proposed project would not be located within one-quarter mile of an existing or proposed school (City of Carlsbad 2002). As such, no impact to existing or proposed schools -would result. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.S and, as a result, would it create a significant hazard to the public or environment? No Impact. According to the County of San Diego Department of Environmental Health website (http://www.co.san-diego.ea.us/deh, accessed in August 2006), two database listings are located along the APE, but no waste, inventory, environmental assessment, or tank information was identified for these sites. A total of eight other listings are located within a one mile radius of the APE. These listings consist of medical/dental facilities and one dry cleaner site. These sites were reported as chemicals storage areas with no reports of hazardous spills or contamination issues. Therefore, no listed sites would create a significant hazard to the public or the environment, and no impact would occur. e) For a project within an airport land use plan, or where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? September 2007 4926-01 El Camino Real Widening Project 55 EIA Form -Part /J No Impact. The proposed project is not located within the McClellan-Palomar Airport Influence Area of the Airport Land Use Compatibility Plan for the McClellan-Palomar Airport (SANDAG 2004). In addition, the proposed project is not located within a two mile radius of any other airport. The McClellan-Palomar Airport is located approximately 2.2 miles south of the proposed project site. No safety hazard or impacts would result. t) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? No Impact. The proposed project is not located within the vicinity of a private airstrip, and no impact would result. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Potentially Significant Impact Unless Mitigation Incorporated. The widening of El Camino Real would alleviate existing and future traffic conditions along this roadway segment. However, during construction activities, the potential exists for increased traffic to occur within the APE which could result in delayed response times to emergency vehicles. Mitigation has been provided below to reduce this short-term impact to less than significant levels: HAZ-1: Prior to grading, a traffic control plan shall be prepared to the satisfaction of the City of Carlsbad Engineering Department. 1lb.e traffic control plan shall show all signage, striping, delineation detours, flagging operations, and any other devices, which shall be used during construction to guide motorists safely through the construction zone and allow for a minimum of one lane of travel. The plan shall also identify temporary construction employee parking areas. The traffic control plan shall also include provisions for coordinating with local emergency service providers regarding construction times and locations of lane closures as well as specifications for pedestrian and bicycle safety. Emergency vehicles would be permitted access through the construction zone. h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? Less than Significant Impact. The proposed project is located in areas adjacent to vegetated open space that could be susceptible to wildland fires. These areas are located on both sides of El Camino Real within and near the project APE. During the construction phase, the use and - - storage of construction equipment fuel and petroleum products would increase the potential risk - September 2007 4926-01 El Camino Real Widening Project 56 - • L. EIA Form -Part II of fire hazard in the area. The project incorporates design features that would comply with County of San Diego Fire Department fuel modification requirements. Therefore, impacts are considered less than significant. VIII. HYDROLOGY AND WATER QUALITY-Would the project: a) Violate any water quality standards or waste discharge requirements? Potentially Significant Impact Unless Mitigation Incorporated. A Water Quality Technical Report (WQTR) was prepared for the proposed project (Bureau Veritas 2007), as required under the City's local Standard Urban Storm Water Mitigation Plan (SUSMP). The purpose of the WQTR is to document the process that was used to select and design the site, source, and treatment control stormwater BMPs that would be incorporated in the project to mitigate the impacts of urban runoff during and after construction. The WQTR identifies the project as "high priority" in the City's SUSMP because it involves a site 5 acres or larger (Bureau Veritas 2007). Also, since the project meets one or more _of the SUSMP applicability criteria, it is required to incorporate permanent stormwater BMPs into the project design. These BMPs include site design, source control, and treatment control BMPs. The project site is located in the Carlsbad Hydrologic Unit of the California Water Quality Control Board's Region 9 -San Diego, within the Agua Hedionda Lagoon and Agua Hedionda Creek Hydrologic Areas. The Carlsbad Watershed Urban Runoff Management Program prepared by the California Water Quality Control Board's Region 9 -San Diego, identified the following major water quality problems in the Carlsbad Hydrologic Unit: fecal coliform or bacterial indicators and sedimentation and siltation. The San Diego Regional Water Quality Control Board 303(d) list of impaired waterbodies included Agua Hedionda Creek for total dissolved solids, and Agua Hedionda Lagoon for bacteria indicators and sedimentation/siltation. The construction phase of the project is anticipated to generate sediment and construction material waste. Sedimentation can typically be caused through erosion of unprotected graded slopes and poor stockpile management. Construction material waste can pollute downstream water bodies, resources and aqueous environments if not treated, handled and disposed of properly. Grading would increase the erosion potential of onsite soils which could lead to offsite sediment transport. Sediment, nutrients, heavy metals, organic compounds, potential oxygen demanding substances, and oil and grease are the potential pollutants generally of concern for roadway projects (Bureau Veritas 2007). This potential impact would be short-term (during the construction phase) and is considered significant. Mitigation in the form of site-specific BMPs, as recommended in the WQTR, would be implemented as discussed below. These mitigation measures would reduce water quality impacts to below a level of significance: September 2007 4926-01 El Camino Real Widening Project 57 EIA Form -Part II HYDR0-1: A stormwater pollution prevention plan (SWPPP) shall be prepared by the City prior to grading. The SWPPP shall identify potential sources of pollution, practices to be - used to reduce pollutants, and shall help ensure compliance with the stormwater permit. The construction contractor shall be required to implement the approved SWPPP and any amendments thereafter, to the satisfaction of the City Engineer. The SWPPP will have a Sampling and Monitoring Program that addresses both direct discharges from the project into a Section 303( d) water body and discharges that have been discovered through visual monitoring to be potentially contaminated by pollutants not visually detectable in the runoff. HYDR0-2: The construction contractor shall be required to implement BMPs during construction in accordance with the plans, specifications and SWPPP prepared for the project, the General Construction Storm Water Permit (NPDES Order 99-08-DWQ), and to the satisfaction of the City Engineer. These BMPs shall address temporary soil stabilization, temporary sediment control, wind erosion control, tracking control, and non-stormwater management. Several BMPs have been incorporated into the project design to reduce potential future impacts related to water quality and water discharge (Bureau Veritas 2007). BMPs would be implemented to address water quality impacts during the planning and design, and operational stages of this project. These project BMPs are included in mitigation measures below, and - would reduce potential long-term water quality impacts to below a level of significance: HYDR0-3: The project is considered a priority project and is therefore required to incorporate treatment BMPs into the site. Based on the impaired waterways that exists downstream of the APE, this project shall incorporate native planted swales as a treatment control BMP designed to remove sedimentation/siltation to a medium or high level. This BMP shall be approved by the City Engineer prior to grading. Native planted swales shall be located along either side of the roadway in the parkway area or in the median as determined by the City during the final design phase of the project. The length and configuration of the native planted swales shall be consistent with those identified in detail in the Water Quality Technical Report prepared ·for the project (Bureau Veritas 2007). HYDR0-4: The City shall implement all maintenance operations of permanent BMPs as outlined in Section 2.5 [Maintenance of Municipal Separate Storm Sewer System (MS4) of their Jurisdictional Urban Runoff Management Plan (JURMP)]. The City's Contractor is responsible for maintenance of construction BMPs. Operation and maintenance requirements for the proposed permanent BMPs are provided in Table 4 below.

Trim shrubbery to no less than 4-inch depth, but no taller than 6-inch depth. Weed control strategies. Regrade areas downstream of location where standing water accumulates to ensure water flows smoothly. b) Substantially deplete groundwater supplies or interfere substantially with ground water recharge such that there would be a net deficit in aquifer volume or a lowering of the local ground water table level (i.e., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? Less than Significant Impact. As described in response VI.a.iii), the project site is mainly underlain by relatively dense Santiago Formation overlain by shallow, fine grained alluvial deposits, without a groundwater table. The widening of El Camino Real from four to six lanes would result in an increase to impervious surfaces along this roadway. No depletion in groundwater supplies would result, and the scale of the project is such that it would not substantially interfere with ground water recharge. Therefore, impacts to groundwater supplies would be less than significant. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner, which would result in substantial erosion or siltation on-or off-site? September 2007 4926-01 El Camino Real Widening Project 59 EIA Fann-Part II Less Than Significant Impact. Although the project would impact adjacent waters of the U.S., as analyzed in Section IV.a), the proposed project will not significantly alter d:rairiage patterns on - the site (Bureau Veritas 2006). Stormwater within the existing storm drains currently flows at erosive velocities into a ditch east of the roadway. This has resulted in erosion of the existing embankment along the east side of the roadway, pavement cracking and weathering, and bumps/sags. The project proposes to replace and/or improve the existing storm drains within the project APE and provide erosion protection in the ditch and/or construct check dams within the ditch. These proposed project features would remedy the existing erosion condition. Impacts would be less than significant. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the flow rate or amount (volume) of surface runoff in a manner, which would result in flooding on-or off--site? Less Than Significant Impact. The proposed project will not significantly alter drainage patterns on the site (Bureau Veritas 2006). The proposed project would replace and/or improve the existing storm drains within the project limits as the majority of the existing system is at capacity. The proposed project would result in a minor increase to surface runoff due to the proposed widening of El Camino Real, and this minor increase in surface runoff would not substantially alter the existing drainage pattern of the site or area. Therefore, impacts would be less than significant. e) Create or contribute runoff water, which would exceed the capacity of existing or planned stormwater drainag,e systems or provide substantial additional sources of polluted runoff? Less Than Significant Impact. The widening of El Camino Real from four to six lanes would result in a minimal increase in runoff, including polluted runoff. As stated in the Preliminary Hydrology/Hydraulics Study for El Camino Real Widening (Bureau Veritas 2006) the majority of the existing storm drain system within the project limit is at capacity and therefore the project is proposing to replace and/or improve the existing storm drains within the project limits to accommodate project runoff. Therefore, impacts would be less than significant. t) Otherwise substantially degrade water quality? Less Than Significant Impact. See responses to Hydrology and Water Quality a) through e) above. September 2007 4926-01 El Camino Real Widening Project 60 - - ----------------------------- EIA Form -Part II g) Place housing within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood delineation map? No Impact. The proposed project does not include the construction of any housing units. In addition, the project is not located within a 100-year flood hazard area (SANG IS 1997). No impact is assessed. h) Place within 100-year flood hazard area structures, which would impede or redirect flood flows? No Impact. The propose project does not propose the construction o_f any structures that would impede or redirect flood flows. In addition, as mentioned above the proposed project is not located within a 100-year flood hazard area. No impact is assessed. i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? No Impact. The proposed project is not located within any inundation area and therefore would not expose people or structures to a significant risk or loss of injury or death involving flooding. No impact assessed. j) Inundation by seiche, tsunami, or mudflow? Less Than Significant Impact. The project site is located approximately I mile northeast of Agua Hedionda Lagoon, 2.5 miles east of the Pacific Ocean, and 1.6 miles south of Buena Vista Lagoon. The proposed project is located approximately 77 to 286 feet above mean see level. Due to the elevation and distance of the Pacific Ocean tsunamis are not considered a hazard at the project site. Due to the shallowness of the lagoons, and the position of the site being upslope from these water bodies, potential impacts from a seiche or mudflow would not result. Therefore, impacts would be less than significant. IX. LAND USE AND PLANNING-Would the project: a) Physically divide an established community? No Impact. The proposed project is located in the northern part of the City and would consist of widening an existing roadway from four to six lanes to accommodate existing and future traffic. The improvement of the existing road facility is consistent with the City's General Plan. Since El Camino Real is an existing roadway, the proposed widening of the roadway would not physically divide an established community, and no impact would result. September 2007 4926-01 El Camino Real Widening Project 61 b) EIA Fann -Part II Conflict with any applicable landl use plan, policy, or regulation of an agency with jurisdiction over the project (including but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? Less Than Significant Impact. The project proposes to widen El Camino Real to its ultimate width of six travel lanes, which is consistent wiith its General Plan designation for prime arterial roadways. As such, no conflict with the General Plan would result, and since the project would provide ultimate Circulation Element configuration improvements for this segment of El Camino Real, a land use policy benefit would result. As shown in Figures 9a through 9d, the project site is located within the Coastal Zone as part of the City's Local Coastal Program (LCP). The project would be consistent with the City General Plan and would not conflict with the LCP. For a discussion on sensitive biological resources within the Coastal Zone, refer to Section IV, Biological Resources, responses a) and b ). The project is also subject to the City's Hillside Development Regulations, per Chapter 21.95 of the City Municipal Code (1998). The key purpose and intent of the regulations is to assure hillside conditions are properly identified and incorporated into the planning process, and to preserve and/or enhance the aesthetic qualities of natural hillsides and manufactured slopes of the land, minimizing the amount of project grading, especially in highly visible public places. The project is subject to a Hillside Development Permit due to its proposed grading and construction of a retaining wall along the western slope of the project segment. As described above under Aesthetics, the project is subjc:ct to El Camino Real Corridor Development Standards and would not conflict with those standards given its incorporation of key features such as a boulderscape retaining wall, landscaping, and other improvements such as sidewalks. These project features would also be consistent with the Hillside Development Regulations since they intend to improve the visual quality of the adjacent hillsides and street corridor. Overall, the project would be consistent with applicable plans, and impacts would be less than significant. c) Conflict with any applicable hab:itat conservation plan or natural community conservation plan? Less Than Significant Impact. As stated in Section IV, Biological Resources item f), the proposed project site is located within the City of Carlsbad's HMP and is part of the El Camino Real Widening -South Chestnut to South Alga street project, which is covered by proposed City Lands mitigation bank. The proposed project would comply with its guidelines and September 2007 4926-01 El Camino Real Widening Project 62 - - - - EIA Form-Part II requirements, and would be consistent with the Carlsbad's HMP. Impacts would be less than significant. X. a) MINERAL RESOURCES -Would the project: Result in the loss of availability of a known mineral resource that would be of future value to the region and the residents of the State? No Impact. According to the California Department of Conservation Division of Mines and Geology's (CDMG) Generalized Mineral Land Classification Map of Western San Diego County, California, the proposed project site and its surrounding areas are classified as Mineral Resource Zone (MRZ)-3 (CDMG 1996). MRZ-3 is defined as areas containing mineral deposits the significance of which cannot be evaluated from available data (CDMG 1996). Also, the City's General Plan does not identify mineral resources within its jurisdictional area. Overall, no impacts to mineral resources would occur. b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan? No Impact. As stated above in response a), the project site is not located in an area designated for possessing locally important minerals. The project site is located in a semi-developed area and consists of widening an existing roadway, with no impacts to any known mineral resource recovery sites. No mineral impacts would result as a result of implementing the proposed project. XI. NOISE -Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance or applicable standards of other agencies? Less Than Significant Impact. An Acoustical Assessment Report was prepared for the project in 2006, and is summarized in this section (Dudek 2006). The City's General Plan has designated the maximum noise exterior level of 60 dBA community noise equivalency level (CNEL) for new residential, schools and churches. In addition, interior noise levels for new residential development should not exceed 45 dBA CNEL. The City has not adopted specific road widening significance thresholds for existing noise sensitive land uses. The existing measured hourly average noise levels ranged from 67 to 72 dBA at the backyards of the adjacent residences along both sides of El Camino Real, within the project APE (Figure 10). September 2007 4926-01 El Camino Real Widening Project 63 '-· 0 I Scale in Feet LEGEND e . Noise Measurement Location G ... Receptor Location D .. APE Boundary El Camino Real Widening Project -MND Noise Measurement & Receiver Locations - - - - EIA Fonn -Part II These noise levels do not account for noise attenuation of any existing barriers such as sound walls or wood fences that exist. Since the existing noise levels exceed the City's threshold, the Acoustical Assessment Report determined that a noise impact would be significant if the traffic noise level increase exceeds three (3) dBA CNEL and either elevates noise levels above the City's noise criteria limits or exceeds three (3) dBA increase above an already noisy existing condition. Noise levels generated by construction equipment would vary greatly depending on factors such as the type and specific model of the equipment, the operation being performed and the condition of the equipment. The maximum noise levels would range from approximately 75 to 95 dBA for the equipment normally used for this type of project. Construction activities are expected to comply with the City's permitted hours of operation --for prime arterials, the City's standard weekday construction hours are 8:30 a.m. to 3:30 p.m. Since this segment of El Camino Real has substantial directional flow, the City may pursue an extension of construction hours until 5:00 p.m. in the afternoon, depending on the direction of EI Camino Real under construction. · The extension of hours would require use of a traffic control plan, as identified in the HAZ-1 mitigation measure (Section VII, Hazards and Hazardous Materials, response g). Because the Tamarack Avenue and Chestnut Avenue intersections have school pedestrians crossing El Camino Real, the contractor would not be allowed to initiate the traffic control plan in either direction before 8:30 a.m. Furthermore, the City may elect to allow construction on Saturdays, in an effort to reduce the overall duration of construction. This option would also result in the need to implement the traffic control plan (per HAZ-1 ). Overall, regardless of which construction scenario the City ultimately pursues, construction activities would comply with the City's permitted hours for construction activities, and would be short-term, and therefore the construction noise impact would be less than significant. The short-term with project CNEL would result in an increase of less than one (1) dBA at the adjacent residences as compared to the short-term noise levels without the project (Dudek 2006). Therefore, short-term noise impacts are considered less than significant, since the noise levels would not exceed the three (3) dBA threshold. Long-term impacts were addressed for the year 2030. Year 2030 noise levels with incorporation of the proposed project would range from approximately 68 to 74 dBA CNEL at the backyards of the adjacent residents along EI Camino Real. The year 2030 with the proposed project CNEL would result in an increase ofless than one (1) dBA at the adjacent residences as compared to the noise levels without the proposed project. Therefore, long-term noise increase impacts would September 2007 4926-01 El Camino Real Widening Project 65 ,.___ (__, EIA Form -Part II also be less than significant, since the project noise increase would not exceed the significance threshold. b) Exposure of persons to or genention of excessive groundbourne vibration or groundboume noise levels? Less Than Significant Impact. During the construction phase of the project, the generation of groundboume vibration or intermittently high noise levels may occur. However, these activities · would occur during the permitted hours of construction activities in compliance with the City's Noise Ordinance and therefore impacts would be less than significant. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant Impact. As mentioned above in response a) the proposed project would result in an increase of one (I) dBA CNEL over the long term. Since a noise level change of three (3) dBA is generally considered to be a perceptible change in environmental noise, a substantial permanent increase in ambient noise level within the project vicinity would not result. The increase in ambient noise level would be less than significant. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant Impact. As mentioned above in response a), the proposed project would result in a temporary noise increase during construction activities. However, construction activities would be permitted to occur in accordance with the hours stated in the City's Noise Ordinance and therefore impact would be less than significant. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? No Impact. The proposed project is not located within 2 miles of a public airport or public use airport. Therefore, no impact would result. t) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? September 2007 4926-01 El Camino Real Widening Project 66 - - - EIA Form -Part II No Impact. The proposed project is not located within the vicinity of a private airstrip. Accordingly, no impact would result. XII. POPULATION AND HOUSING-Would the project: a) Induce substantial growth in an area either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? Less Than Significant Impact. The widening of El Camino Real to the proposed configuration of this segment of roadway would accommodate planned development consistent with the City's General Plan. The widening of.this existing roadway from four to six lanes would not induce substantial unplanned growth in the area, and would not change any allowed density and/or zoning on adjacent properties. Impacts would be less than significant. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? No Impact. As identified in the project description, the proposed project would result in the acquisition of 6,946 square feet (0.16 acre) of private property on the western side of EI Camino Real, affecting parts of 4 parcels. These parcels are privately owned and currently vacant. There are no structures within the proposed acquisition area and no displacement of existing housing would result. Also, no change to allowed density or zoning would result. Therefore, no impact would result. The City of Carlsbad would work with the private property owner to determine the fair market value of the property to be acquired. Also, the proposed grading across APNs 167- 230-24 and 167-230-25 along the northeast portion of the APE would not result in impacts to existing housing. No housing would be displaced, and the proposed grading would be performed in such a fashion as to replace the in-kind driveway access to the property. c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? No Impact. Refer to response b) above. No people would be displaced as a result of implementing the proposed project. No impact assessed. XIII. PUBLIC SERVICES -Would the project: a) Result in substantial adverse physical impacts associated with the provision of new or physically altered government facilities, a need for new or physically altered government facilities, the construction of which could cause significant September 2007 4926-01 El Camino Real Widening Project 67 EIA Form -Part II environmental impacts, in order to maintain acceptable service ratios, response A times, or other performance objecltives for any of the public services: W i) Fire protection? Potentially Significant Impact Unless Mitigation Incorporated. The nearest fire protection station, Fire Station 3, is located approximately 300 feet northeast of the project site at 3701 Catalina Drive. The widening of El Camino Real would alleviate the existing traffic congestion along the roadway and allow better access for public emergency services and improve their response times. The demand for fire services in the area is not expected to increase as a result of implementing the proposed project. Temporary construction phase impacts may result during project construction, and as identified in HAZ-1 mitigation measure provided in the Hazards and Hazardous Materials section, response g), the Traffic Control Plan would ensure that emergency response services would be provided with information concerning the closures and the applicable contract information to reach the onsite construction manager. This would allow prior notification to ensure that access ~hrough the construction area is possible upon arrival of an emergency vehicle. Therefore, temporary impacts during the construction phase would be reduced to less than significant. No long-term operational phase impacts are assessed. ii) Police Protection? Potentially Significant Impact Unless Mitigation Incorporated. The City of Carlsbad maintains one police station at 2560 Orion Way. The station is located approximately 1.2 miles southeast of the proposed project site. The demand of police protection services is not anticipated to increase with implementation of the proposed project, and no impacts were assessed for the long-term operational phase of the proposed project. As described in response i) above, the Traffic Control Plan provided in Hazards and Hazardous Materials section, response g), would ensure that temporary impacts would be reduced to less than significant. Since emergency response s~rvices would be provided with information concerning any potential road closures and the applicable contract information of the onsite construction manager to ensure prior_ notification of access, temporary impacts would be less than significant. iii) Schools? No Impact. The proposed project would not affect existing or proposed schools within the area, since no housing is proposed, and no increase in students would result. No impact assessed. September 2007 4926-01 El Camino Real Widening Project 68 - - - EIA Form -Part II iv) Parks? No Impact. The proposed project would not result in the increased use of existing parks, since no population would be introduced as a result of the project. No impact assessed. v) Other public facilities? No Impact. No additional public facilities, such as public libraries, would be impacted as a result of the proposed widening of El Camino Real. No impact assessed. XIV. a) RECREATION-Would the project: Increase the use of• existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? No Impact. The proposed widening of El Camino Real and its project components would not result in the use of existing neighborhood and regional parks or other recreational facilities. No impact is assessed. b) Include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? No Impact. The proposed project does not include recreational facilities or require the construction or expansion of recreational facilities. It should also be noted that the City's General Plan does not propose any recreational facilities within the APE. No impact assessed. xv. a) TRANSPORTATION/TRAFFIC-Would the project: Cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the street system? No Impact. El Camino Real, between Chestnut Avenue and Tamarack Avenue, currently consists of two northbound and two southbound traffic lanes. The City of Carlsbad's General Plan has designated this road as a prime arterial roadway. Various developments in the project vicinity have resulted in requirements of developers to widen El Camino Real to its full prime arterial standards. The proposed project area is one of the few remaining sections of El Camino Real that has not been widened to its ultimate width of three southbound lanes and three northbound lanes. The proposed project consists of the widening of El Camino Real, from Chestnut A venue to Tamarack A venue, to its ultimate width of three lanes in each direction. The September 2007 4926-01 El Camino Real Widening Project 69 - EIA Form -Part II widening of this roadway would help to alleviate traffic along this segment. The project consists of road widening improvements and therefore does not generate traffic. - As described in the MND project description, based on recommendations provided in the traffic study, the project plans include improvements at the El Camino Real/Tamarack A venue intersection, consisting of an additional northbound and southbound thru lane on El Camino Real, and an additional northbound left-tum lane on El Camino Real at the intersection, as shown in Figure 5. With these improvements in place:, future 2030 operating conditions would result in LOS D at this intersection, and no impacts would result. The traffic study projected a year 2030 LOS D for the El Camino Real / Chestnut intersection (LLG 2006). No other deficiencies or impacts were identified, and therefore no impacts would result. b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? No Impact. SANDAG, acting as the County Congestion Management Agency, has designated three roads (Rancho Santa Fe Road, El Camino Real and Palomar Airport Road) and two highway segments in Carlsbad as part of the regional circulation system. The Existing and Buildout average daily traffic (ADT) an9 Existing LOS on these designated roads and highways in Carlsbad are: ExislingADT* LOS Buildout ADT" Rancho Santa Fe Road 17-315 "A-D" 35-56 El Camino Real 27-4!;) "A-C" 33-62 Palomar Airport Road 10-57 "A-Q" 30-73 SR78 124-142 "P 156-180 1-5 199-2'16 "D" 260-272 *The numbers are in thousands of daily trips. The Congestion Management Program's (CMP) acceptable LOS standard is E, or LOS F if that was the LOS in the 1990 base year (e.g., SR 78 in Carlsbad was LOS Fin 1990). Accordingly, all designated roads and highways are currently operating at or better than the acceptable standard LOS. Note that the CMP buildout ADT projections are based on the full implementation of the region's general and community plans. The proposed project is consistent with the City General Plan (including the Circulation Element) and, therefore its traffic was used in modeling the buildout projections. Achievement of the CMP acceptable LOS E standard assumes implementation of the adopted CMP strategies. Based on the design capacities of the designated September 2007 4926-01 El Camino Real Widening Project 70 - - EIA Form -Part II roads and highways and implementation of the CMP strategies, they will function at acceptable levels of service in the short-term and at buildout. The traffic study forecasted 2030 volumes for El Camino Real between Chestnut A venue and Tamarack Avenue to be 34,700 ADT (LLG 2006). This buildout ADT volume is consistent with what is projected by the County's Congestion Management Agency, and no impacts would result. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? No Impact. The proposed project does not include any aviation components, and no part of the proposed roadway improvements would conflict with the Comprehensive Land Use Plan for the McClellan-Palomar Airport. It would not result in a change of air traffic patterns or result in substantial safety risks, and no impacts would result. d) Substantially increase hazards due to a design feature or incompatible uses? No Impact. All project circulation improvements would be designed and constructed to City standards and no feature of the project would result in a design hazard. The proposed project is consistent with the City's General Plan and would not result in any incompatible land uses. Overall, no impacts would result. e) Result in inadequate emergency access? Potentially Significant Impact Unless Mitigation Incorporated. The proposed project has been designed to satisfy the emergency requirements of the Fire and Police Departments. During the construction phase lane closures along El Camino Real (within the project boundary) could occur, which could result in inadequate emergency response times. However, with implementation of a Traffic Control Plan, potential impacts would be reduced to less than significant levels. Refer to HAZ-1 mitigation measure in Section VII, Hazards and Hazardous Materials, response g). f) Result in inadequate parking capacity? No Impact. Parking is currently prohibited along El Camino Real, within the project boundary. The proposed project would not produce the need for increased parking facilities within the APE. Construction staging areas including employee parking areas would be defined in the Traffic Control Plan that is described in the HAZ-1 mitigation measure provided above in the Hazards and Hazardous Materials section, response g). No impacts to parking would result. September 2007 4926-01 El Camino Real Widening Project 71 g) EIA Form -Part II Conflict with adopted policies, plans or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks, etc.)? Less Than Significant Impact. An existing North County Transit District (NCTD) bus stop is located on the west side of El Camino Real just south of Chestnut A venue. This existing bus stop would be relocated within the project APE, although no specific location has yet been determined by the City. No bicycle racks or other alternative transportation is provided along this portion of El Camino Real. A bicycle lane~ is currently located on both sides of El Camino Real, and the widening of this roadway segment involves the reconstruction of the bicycle lanes. During construction of the proposed project, access to one of the two bicycle lanes would be provided at all times. Therefore the redirected bicycle route would 1;,e short term. For these reasons, the project would not conflict with alternative transportation programs and impacts would be less than significant. XVI. UTILITIES AND SERVICES SYSTEMS -Would the project: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? No Impact. Project implementation would not impact wastewater treatm<:;nt services of the applicable wastewater service provider, since 1the project involves a roadway widening project with no alteration to vicinity wastewater services. No impact woul~ result. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which would cause significant environmental effects? No Impact. The proposed project would not result in the construction of a new water or wastewater treatment facility, and would not entail the expansion of existing facilities, since water and wastewater systems are not proposed to be altered. Therefore, no impacts would result. c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the: construction of which could cause significant environmental effects? Potentially Significant Impact Unless Mitigation Incorporated. According to the Preliminary Hydrology/Hydraulics Study for El Camino Real Widening (Bureau Veritas 2006), the majority of the existing storm drain systems within the project limits are at capacity. As identified in the project description, the project proposes to replace or improve the existing storm drains within September 2007 4926-01 El Camino Real Widening Project 72 - - - EIA Form -Part II the APE and provide erosion protection in the existing ditch. These improvements have the potential to result in significant effects to biological resources as analyzed in that section, since waters and wetlands would be significantly affected. Mitigation provided under response b) in Section IV, Biological Resources, would reduce potential impacts to less than significant. d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? Less Than Significant Impact. The proposed project would require minimal new water supplies to serve irrigation needs of the project. Also, the project does not meet the requirements of a "regionally significant project" per Senate Bill (SB) 610 as it would not require expanded use of water supplies. Therefore, the project is not subject to enhanced CEQA requirements per SB 610. Impacts would be less than significant. e) Result in a determination by the wastewater treatment provider, which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? No Impact. The City owns and maintains sewage pipelines, pump stations and other facilities used to convey wastewater for treatment. Within the City, the wastewater system is comprised of major trunk lines, smaller collector lines, and lift stations. Wastewater treatment services are provided by the Encina Wastewater Authority (EWA). Project implementation would not impact wastewater treatment, since no demand would result with implementation of the road widening project. No impact would result. f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? Less Than Significant Impact. Solid waste disposal is provided by Waste Management, Inc., which operates under a franchise agreement with the City. The project would generate a limited amount of solid waste during construction. It is anticipated that the solid waste generated by ,"~ project construction would not be substantial or interfere with the permitted capacity of nearby landfills and therefore would have a less than significant impact on local solid waste facilities. No regular solid waste disposal is proposed as part of project operations. Impacts would be less than significant. g) Comply with federal, state, and local statutes and regulations related to solid waste? No Impact. All solid waste would be disposed of in an approved site in compliance with federal, state and County regulations (see response f) above). No impacts would result. September 2007 4926-01 El Camino Real Widening Project 73 \ ........ t EIA Form -Part II XVII. MANDATORY FINDINGS OF SIGNIFICANCE a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Potentially Significant Impact Unless Mitigation Incorporated. Based on evaluation and discussions contained in this Initial Study and MND, the proposed project has limited potential to degrade the quality of the environment. The proposed project would not significantly affect the environment with the recommended mitigation measures incorporated into the project, particularly for the topics of biological resources and cultural resources as analyzed herein. b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project ·are considerable whe111 viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects?) Potentially Significant Impact Unless Miti~~ation Incorporated. Mitigation measures are provided to reduce the project's significant impacts to biological resources, cultural resources, geology/soils, hazard and hazardous materials, hydrology and water quality, public services, transportation/traffic, and utilities and service systems. With the incorporation of the project mitigation measures identified in this MND, project-level impacts to the environment would be reduced to less than significant levels, arid impacts would not be cumulatively considerable when viewed in connection with the effects of reasonably foreseeable projects. c) Does the project have environmt~ntal effects, which will cause the substantial adverse effects on human beings, e:iither directly or indirectly? Less Than Significant Impact. No feature of the proposed project would result in substantial adverse effects on human beings, either directly or indirectly. Impacts would be less than significant.

Mitigation measures for impacts to southern willow scrub are discussed below under response b ). Mitigation Measures for Sensitive Wildlife Sp~ BI0-2:Prior to grading, significant direct impacts to sensitive wildlife species shall be mitigated to the satisfaction of the City Planning Department. The following mitigation measures would avoid impacts to Cooper's hawk, other raptors and other migratory bird species nests protected under the Migratory Bird Treaty Act: • • The City's construction contractor shall conduct vegetation clearing outside of the January through September bird lbreeding season; or A qualified biologist shall conduct a focused survey for bird nests not more than 72 hours prior to commencement of vegetation clearing activities. If active nests are found, the City's construction contractor shall cease construction within an appropriate buffer zone of 50 to 300 feet, as determined by the project biologist, around the nest site until juveniles have fledged and the nesting cycle is complete. Impacts to Cooper's hawk, Dulzura Californ:ia pocket mouse, and northwestern San Diego pocket mouse shall be mitigated through creation and/or preservation of riparian scrub and eucalyptus woodland (Cooper's hawk), and coastal sage scrub and grassland (pocket mice) habitats discussed under BIO-I above. [Note: the loss of approximately 0.7 acre of potential Cooper's hawk nesting habitat (eucalyptus and riparian scrub) shall be mitigated through creation or preservation of 1.20 acres of riparian habitat and 0.03 acre of eucalyptus woodland.] The location of the riparian scrub would be determined as part of the CDFG 1602 permit process. September 2007 4926-01 El Camino Real Widening Project 78 - - - EIA Fonn -Part II Mitigation Measures for Jurisdictional Waters BI0-3 Prior to grading, significant direct impacts to jurisdictional waters and riparian habitats shall be mitigated to the satisfaction of the City Planning Department. The following mitigation measures would reduce impacts to a level below significance: • Mitigation for impacts to jurisdictional waters and riparian habitats shall include 1: 1 creation in accordance with the "no net loss" wetlands policy in the Carlsbad HMP. Impacts to 0.40 acre of southern willow scrub shall be mitigated at a ratio of 3: I, consisting of creation of 0.40 acre (1: I) of southern willow scrub and use of 0.80 acre (2:1) of mitigation credit in the City of Carlsbad's Lake Calavera Mitigation Bank. • • • • • Impacts to 0.12 acre of ephemeral and intermittent stream channels shall be mitigated through creation of0.12 acre of stream channel (or superior) habitat. A combined total of 0.52 acre of wetland habitat and jurisdictional stream channels shall be created in partial mitigation for wetland impacts. A Clean Water Act (CWA) Section 404 Nationwide Permit shall be required from the ACOE for project impacts to 0.19 acre of ACOE-jurisdictional waters. A CWA Section 401 permit from RWQCB shall be required for impacts to 0.19 acre of waters under their jurisdiction. A CDFG Section 1602 Streambed Alteration Agreement shall be required from CDFG for impacts to 0.52 acre of jurisdictional waters and riparian vegetation .. Cultural Resources CUL T-1: Archeological monitoring shall occur during all earthmoving activities, to the satisfaction of the City of Carlsbad Planning Department.

Photographs can be used to document general conditions on a reach of a stream during a stream walk, pollution events or other impacts, assess resource conditions over time, or can be used to document temporal progress for restoration efforts or other projects designed to benefit water quality. Photographic technology is available to anyone and it does not require a large degree of training or expensive equipment. Photos can be used in reports, presentations, or uploaded onto a computer website or GIS program. This approach is useful in providing a visual portrait of water resources to those who may never have the opportunity"to actually visit a monitoring site. Equipment: Use the same camera to the extent possible for each photo throughout the duration of the project. Either 35 mm color or digital color cameras are recommended, accompanied by a telephoto lens. If you must change cameras during the program, replace the original camera with a similar one comparable in terms of media (digital vs. 35 mm) and other focal length characteristics. A complete equipment list is suggested as follows: Required: • Camera and backup camera • Folder with copies of previous photos (do not carry original photos in the field) • Topographic and/or road map • Aerial photos if available • Compass • Timepiece • Extra film or digital disk capacity (whichever is applicable) • Extra batteries for camera (if applicable) • Photo-log data sheets or, alternatively, a bound notebook dedicated to the project • Yellow phot<? sign form and black marker, or, alternatively, a small black board and chalk Optional: • GPS unit • Stadia rod (for scale on landscape shots) • Ruler (for scale. on close up views of streams and vegetation) • Steel fence posts for dedicating fixed photo points in the absence of available fixed landmarks 1 Attachment 6 · Certification No. 08C-07 4 • Poisonous plants (e.g.: poison oak) • Dangerous insects and animals (e.g.: bees, rattlesnakes, range animals such as cattle, etc.) • Harmful or hazardous trash (e.g.: broken glass, hypodermic needles, human feces) We recommend that the volunteer coordinator or leader discuss the potential hazards with all volunteers prior to any fieldwork. General Instructions: From the inception of any photo documentation project until it is completed, always take each photo from the same position (photo point), and at the same bearing and vertical angle at that photo point. Photo point positions should be thoroughly documented, including photographs taken of the photo point. Refer to copies of previous photos when arriving at the photo point. Try to maintain a level (horizontal) camera view unless the terrain is sloped. (If the photo can not lbe horizontal due to the slope, then record the angle for that photo.) When photo points are first being selected, consider the type of project (meadow or stream restoration, vegetation management for fire control, ambient or event monitoring as part of a stream walk, etc.) and refer to the guidance listed on Suggestions tor Photo Points by Type of Project. When taking photographs, try to include landscape features that are unlikely to change over several years (buildings, other structures, and landscape features such as peaks, rock outcrops, large trees, etc.) so that repeat photos will be easy to position. Lighting is, of course, a key ingredient so give cqnsideration to the angle of light, cloud cover, background, shadows, and contrasts. Close view photographs taken from the north (i.e., facing south) will minimize shadows. Medium and long view photos are best shot with the sun at the photographer's back. Some artistic expression is encouraged as some photos may be used on websites and in slide shows (early morning and late evening shots may be useful for this purpose). Seasonal changes can be used to advantage as foliage, stream flow, cloud cover, and site access fluctuate. It is often important to include a ruler, stadia rod, person, farm animal, or automobile in photos to convey the scale of the image. Of particular concern is the angle from which the photo is taken. Oftentimes an overhead or elevated shot from a bridge, cliff, peak, tree, etc. will be instrumental in conveying the full dimensions of the .project. Of most importance overall, however, is being aware of the goal(s) of the project and capturing images that clearly demonstrate progress towards achieving those goal(s). Again, reference to Suggestions for Photo Points by Type of Project may be helpful. If possible·, try to include a black board or yellow photo sign in the view, marked at a minimum with the location, subject, time and date of the photograph. A blank photo sign form is included in this document. 3 -t l . i I - - - Attachment 6 Certification No. 0SC-O7 4 2. Select an existing structure or landmark (mailbox, telephone pole, benchmark, large rock, etc.), identify its latitude and longitude, and choose (and record for future use) the permanent position of the photographer relative to that landmark. Alternatively, choose the procedure described in Monitoring California's Annual Rangeland Vegetation (UC/DANR Leaflet 21486, Dec. 1990). This procedure involves placing a permanently marked steel fence post to establish the position of the photographer. 3. For restoration, fuel reduction, and BMP projects, photograph the photo-points and carry copies of those photographs on subsequent field visits. Determining the Compass Bearing: 1. Select and record the permanent magnetic bearing of the photo center view. You can also record the true compass bearing (corrected for declination) but do not substitute this for the magnetic bearing. Include a prominent landmark in a set position within the view. If possible, have an assistant stand at a fixed distance from both the photographer and the center of the view, holding a stadia ·rod if available, within the view of the camera; preferably position the stadia rod-on one established, consistent side of the view for each photo (right or left side). 2. Alternatively, use the procedure described in Monitoring California's Annual Rangeland Vegetation (UC/DANR Leaflet 21486, Dec. 1990). This procedure involves placing a permanently marked steel fence post to establish the position of the focal point (photo center). 3. When performing ambient or event photo monitoring, and when a compass is not available, then refer to a map and record the approximate bearing as north, south, east or west. Sugg~stions for Photo Points ·by Type of Project: Ambient or Event Monitoring, Including Photography Associated with Narrative Visual Assessments: 1. When first beginning an ambient monitoring program take representative long and/or medium view photos of stream reaches and segments of shoreline being monitored. Show the positions of these photos on a map, preferably on the stream/shore walk form. Subjects to be photographed include a representative view of the stream or shore condition at the beginning and ending positions of the segment being monitored, storm drain outfalls, confluence of tributaries, structures (e.g., bridges, dams, pipelines, etc.). 2. If possible, take a close view photograph of the substrate (stream bed), algae, or submerged aquatic vegetation. 3. -Time series: Photographs of these subjects at the same photo points should be repeated annually during the same season or month if possible. 5 Attachment 6 Certification No. 0BC-07 4 Vegetation Management for Fire Prevenition ("fuel reduction"): 1. Aerial view (satellite or airplane photography) if available. 2. In the absence of an aerial view, a landscape, long view showing all or representative sections of the project (bluff, bridge, etc.) 3. Long view (wide angle if possible} showing1 the project area or areas. Preferably these long views should be from an elevated vantage point. 4. Medium view photos showing examples of vegetation changes, and plantings if included in the project. It is recommended that a person (preferably holding a stadia rod) be included in the view for scale 5. To the extent possible include medium and long view photos that include adjacent stream channels. Stream Sediment Load or Erosion Monitoring: 1. Long views from bridge or other elevated position. 2. Medium views of bars and banks, with a pE3rson (preferably holding a stadia rod) in view for scale. 3. Close views of streambed with ruler or oth1;r common object in the view for scale. 4. Tir,:te series: Photograph during the dry se,:ilson (low flow} once per year or after a significant flood event when streambed is visible. Th13 flood events may be episodic in the south and seasonal in the north. 5. Optional: Use a tape set perpendicular across the stream channel at fixed points and include this tape in your photos described iin 1 and 2 above. For specific procedures refer to Harrelson, Cheryl C., C.L. Rawlins, and John P. Potyondy, Stream Channel Reference Sites: An Illustrated Guide to Field Techniques, United States Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station, General Technical Report RM-245. . 7 - - - - - - Attachment 6 Certification No. 0BC-07 4 PHOTO SIGN FORM: Print this form on yellow paper. Complete the following information for each photograph. Include in the photographic view so that it will be legible in the finished photo. Location: Subject Description: Date: Time: _, 9 July 10, 2007 Mr. Shawn Shamlou Dudek & Associates 605 Third Street ·ASM affiliates archaeology history arch1'.ectura1 i'l1story ethnography Encinitas, California 92024 Re: Cultural Resource Report for the El Camino Real Widening Project, Carlsbad, San Diego County, California. Dear Mr. Shamlou, This letter report summarizes a cultural resource study conducted by ASM Affiliates, Inc. (ASM) for the widening of El Camino Real from Tamarack A venue to Chestnut A venue in Carlsbad, San Diego County, California. The study included a records search conducted at the South Coastal Information Center and San Diego Museum of Man, and a pedestrian survey of the project. No cultural resources were identified within the project area as a result of this study. Project Description The City of Carlsbad (City) proposes to improve the section of El Camino Real from Tamarack A venue north to Chestnut A venue. El Camino Real is a major north/south roadway serving as a vital parallel circulation element to Interstate 5 (1-5) for the Cities of Encinitas, Carlsbad and Oceanside. As various developments including subdivisions have occurred in the project vicinity, developers have been required to widen El Camino Real to full prime arterial standards. This section of roadway, from Tamarack A venue to Chestnut A venue, is one of the few remaining sections of the El Camino Real that has not been widened to its full width of six travel lanes with three northbound and three southbound lanes. The proposed roadway improvements would result in a total width of 126 feet including: • 8-foot-wide bike lanes on both sides of the roadway • three southbound lanes of 12-foot width each • three northbound lanes of 12-foot width each • an 18-foot wide landscaped median island • 5 ½-foot-wide sidewalks on both sides of the roadway • 4 ½ wide native planted area (including a bioswale) on both sides of the roadway In the middle section of the roadway, the roadway would transition between the previously discussed typical section to a modified width of 116 feet including: • a 6 ½ -foot bike lane on the west side ofthci roadway • a 5-foot bike lane on the east side • three southbound lanes, 12 feet wide each • a 14-foot-wide landscaped median island • three northbound lanes, 11 ½ -feet wide eac:h - - - - - - Mr. Shawn Shamlou July 10, 2007 Page 2 of13 • 5 ½ -foot wide sidewalks on both sides of the roadway • 4 ½ -foot wide native planted_ area (including a bioswale) on both sides of the roadway The project proposes to keep the existing vertical profile of the road, and construction is anticipated to extend approximately nine months. Additional characteristics of the proposed project are described below. Intersection Improvements. A traffic study was prepared for the subject project in April 2006 (LLG 2006). The purpose of the report was to analyze the operations at the two intersections along this segment of El Camino Real, for the existing conditions and Year 2030 conditions. The report then identified intersection improvements required to achieve acceptable level of service (i.e., LOS D). These intersection improvements were consequently incorporated into the project design. The 2030 traffic forecast analysis shows that in 2030, the El Camino Real/Tamarack A venue intersection would result in an LOS F during AM and PM peak hours (LLG 2006). As such, the project plans include an additional northbound and southbound thru lane on El Camino Real, and an additional northbound left- tum lane on El Camino Real at its intersection with Tamarack A venue. This improvement would improve the LOS at this intersection to LOS D or better in the AM peak hour and LOS C in the PM peak hour. Accommodating the additional northbound and southbound lanes, just north of the intersection, would consist primarily of re-striping the existing roadway, as sufficient width exists within the current roadway geometty. Associated signal modifications to accommodate the new lane configuration would also be provided. At the El Camino Real/Chestnut A venue intersection, the project would result in the removal of the existing free right turn islands located at the northwest and southwest comers of the intersection and replace these with standard curb returns, pedestrian ramps, and associated signal modifications to accommodate the road widening improvements. These intersection improvements must satisfy Americans with Disabilities Act (ADA) requirements, and therefore, ramps that meet ADA gradient criteria would be constructed near the northwest and southwest comers to connect the improvements to existing sidewalks. Storm Drains. Currently, the roadway in the APE exhibits erosion on the embankment on the east side, pavement cracking and weathering, and bumps/sags. Storm water from the storm drains currently outlets at erosive velocities into a ditch east of the roadway. Storm drains within the APE would be replaced and/or improved.. The project includes the placement of erosion protection in the ditch and/or construction of check dams within the ditch to remedy the issue. The pavement for the roadway would be overlaid with asphalt concrete and/or replaced with a full structural section as necessary. Brow ditches are proposed along the west side of El Camino Real to prevent hillside stormwater from flowing over the sidewalk and onto El Camino Real. The proposed locations are at Stations 513+50 and 536+00. The sizes of the brow ditches would vary from approximately 12-inch minimum depth to 24- inch maximum depth. Liglrting. Overhead lighting is proposed as part of the project. Lighting would be installed per applicable City standards for wattage and spacing. Each light pole would produce up to 22,000 lumens and would be staggered at 300-foot intervals along both sides of the project section of El Camino Real. Bus Stops. One existing North County Transit District (NCTD) bus stop located on the west side of El Camino Real just south of Chestnut A venue would be relocated as part of the project, although the specific location is in the process of being determined in concert with North County Transit District. It is assumed that the chosen location would not be located outside of the project Area of Potential Effects Mr. Shawn Shamlou July IO, 2007 Page 3 of13 (APE). A second bus stop exists along the east side of El Camino Real north of Tamarack Avenue. No improvements or alterations to this bus stop are proposed. Utilities. Depending on the availability of funding,. the existing overhead power lines along the west side of El Camino Real may be undergrounded as part of the project. Should funding be available at the time of construction, possibly as a joint cost sharing effort with SDG&E, the City would underground these electrical utilities. The existing power poles along the west side, north of APN 207-090-20, Station 526+00, are currently proposed to be relocated 5 to 10 feet to the west. The relocation of these poles is necessary to accommodate the proposed street widening. No undergrounding of utilities is proposed along the east side of this segment of El Camino Re:al. Grading. Minor grading would occur along the west side of El Camino Real to accommodate construction of proposed retaining walls, which are described below. Additional grading behind and at the top of the retaining walls would occur to construc;t brow ditches and drainage facilities. The proposed grading at the top of the walls would be contoured to a 1.5: 1 or 2: 1 inclination to blend into the natural look of the existing terrain. The proposed grading would range from 5 to 8 feet in height above the top of wall. · Both minor grading and major grading would occur on the east side of the project. Minor re-grading is required at two locations (at approximately Station 512+50 and Station 517+00) to stabilize the existing fill slope adjacent to the east edge of the roadway, which also represents the west edge of the existing drainage channel. These two locations are situated approximately in the middle third of the APE and represent distressed areas where slope failure (Station 512+50) and sloughing (Station 517+00) have occurred. The existing slope height at these areas varies from 5 feet or less to approximately 15 feet with the height generally increasing toward the north. Both of these areas would be over-excavated and - reconstructed with reinforced earth or equal methods in accordance with the geotechnical report for the project to stabilize the slope and re-establish the initial slope inclination. Major grading is proposed along the northern segment of the east side of El Camino Real, predominantly across Assessor Parcel Numbers 167-230-24 and 167-230-25. Slope heights would range from 30 to 50 feet with the height increasing toward the south. The proposed grading will be contoured to a 1.5:1 or variable slope inclination and be graded in such a fashion as to replace the in-kind driveway access to the property. Retai11i11g Walls. Retaining walls are proposed on the west side of El Camino Real in the approximate midpoint of the APE. A portion of the proposed retaining walls would be located outside of the project ROW, therefore, property acquisition of 6,946 square feet (0.16 acre) would be required on Czajkowski property (within parcel numbers 207-180-08, -09, -10, and-12), which is located approximately 2000 feet south of the El Camino Real/Chestnut A venue intersection. The height of the retaining walls would vary from 6 feet to a maximum of 15 feet high. The specific wall types would be Caltrans cast-in-place concrete or masonry block cantilever with fascia for walls less than 10 feet in height. These have a concrete spread footing and a vertical retaining face. For walls over 10 feet in height, a tieback wall type would be implemented. This type of retaining wall is an anchored wall system that relies on steel bars grouted into the retained slope and a reinforced facing. The anchors are prestressed to provide an active clamping force. The facing is typically constructed with reinforced shotcrete or cast-in-place concrete, and are constructed with a "top-down" approach that does not require substantial excavation behind the wall face. The retaining walls are proposed to be built with a boulderscape architectural treatment and landscaping A screening. Drainage systems would be included behind the walls to allow proper drainage of the adjacent • hillside. - - Mr. Shawn Shamlou July 10, 2007 Page 4 of 13 Landscape Concept Plan. A Landscape Concept Plan has been prepared as part of the project to provide a transition between the ornamental landscape and natural landscape on either sides of the project reach of El Camino Real. The Landscape Concept Plan takes into account the City's El Camino Real Corridor Development Standards by incorporating a median landscape treatment that continues adjacent median designs. The specific objectives of the design include low water use, minimization of fire hazards, minimization of visual impacts of the proposed retaining walls, and stabilization of disturbed slopes. Staging Areas. Staging areas for temporarily storing construction equipment would be identified during final design of the project, and would be located within previously paved areas within the APE. Existing Conditions Residential development has occurred along both sides of this segment of El Camino Real. Above ground utilities have been constructed along the length of both sides of the project and a concrete-lined drainage ditch has been constructed on the west side of the project. There is a small grove of mature eucalyptus trees located at the northwest comer of the prqject area (Figures 3 and 4). South of the eucalyptus grove, there are a number of private residences with a gravel-covered driveway connecting EI Camino Real to asphalt-paved driveways extending to the residences. The portion of the project located south of the residences has steep slopes overlain by a relatively level, heavily vegetated area. A rather large drainage is located along the southern half of the east side of the project. A disced area is maintained along the eastern edge of the drainage. A paved sidewalk runs along the east side of the project, most of which is open space with a mix of native and non-native grasses and low shrubs. The northern portion of the east side of the project is a vertical cutbank. Soil deposits in the project include Marina loamy coarse sand in the far northwestern portion of the project, Gaviota fine sandy loam in the northeastern portion of the project, and Salinas clay loam throughout the remainder of the project. Records Search Results Records searches for the project were prepared by the South Coastal Information Center (SCIC) on March 9, 2006 and the San Diego Museum of Man on March 4, 2006. The records searches included a review of archaeological site locations, bibliographic information, historic maps, and other databases of historic resources. While the records searches identified numerous archaeological resources located within one mile of the project, none of these is identified within the project area itself. The results of the records searches are summarized below (Table 1 ). Sites on file at the SCIC are assigned with trinomial designations, noted with a CA-SDI-prefix; those that have been assigned a primary number are noted with a P-37-prefix. Sites on file with the Museum of Man are noted with a SDM-W prefix. The full results of the records search are considered confidential as they identify the location of archaeological sites outside of the current project area. The cover letters for the searches are provided in Appendix A. The remainder of the results will be maintained on file with ASM. Table I.

The site was recorded by Rogers and later updated by Norwood (1977) and Cardenas and Wade (1985). Cardenas and Wade tested the site for the Rising Glen development in 1985. The updated site form notes that 21 lx2m2 test units were excavated and that, while the site is legally mitigated, it still held research potential. The site was monitored during grading for the Rising Glen development in 1986. SDI-5214/SDM-W-1331 is a prehistoric habitation that includes a large shell midden, lithic and ground stone and ceramic artifacts and one possible milling station. The site record mentions that plowing impacted the land and a large private residence is now present on the property. Fifty-one cultural resource surveys have been conducted within a one-mile radius of the project (Table 2). Of these, five bisected the project area. The previous cultural resource surveys conducted within the study area include the following: Table 2.

El Camino Real is a major, paved thoroughfare dating from the Mission Era and extending in a continuous route from the International Border to San Francisco; however no known historic sites are recorded within the project area. A search of the GeoFinder database, which includes information from the National Register of Historic Places, California Register of Historic Resources, California State Landmarks, California Points of Historic Interest and other historic property lists was included with the records search results; no such properties were identified. Study Results ASM Archaeologists Drew Pallette and Catherine, A. Wright surveyed the area of potential effects on March 27, 2006 and April 5, 2006. For the most part, the project is paved or otherwise developed with utilities and a concrete-lined drainage ditch. Both sides of the project have segments with steep-sided, heavily vegetated slopes and these areas were subjected to purposive survey. The remainder of the project was surveyed at 10-meter intervals. A small grove of mature eucalyptus trees is located in the northwestern portion of the project. This area has been subjected to extensive manual excavation, most likely from children constructing ramps and jumps for off-road bicycling (Figure 5); the remainder of the grove is covered with a heavy leaf litter. The area that had been excavated was subjected to dose inspection, as it was the best indicator of possible subsurface archaeological deposits. One piece of marine shell and one fragment of the end of a large mammal bone were identified in this area. However, no further manifestations of cultural resources were identified even after an intensive study of excavated areas and the resulting backdirt. The west-central and southwest portions of the project are comprised of cut slope extending essentially to the edge of pavement or to the edge of the sidewalk. Portions of this area have swaths of open land on top of the slopes and, when accessible, these were surveyed. For the most part, however, these areas were heavily vegetated and ground visibility was moderate at best. - - - Mr. Shawn Shamlou July 10, 2007 Page 8 ofl3 The eastern side of the project area consists of a rather deep drainage located approximately 30 feet east of the eastern edge of pavement. A disced area is maintained on the eastern side of the drainage and there is a small section of cut slope at the northern end of the project. Most of the east side of the project area is western-sloping open space with a mix of native and non-native grasses and low shrubs. The more level areas of this portion of the project were subjected to intensive survey; the steep slopes and drainage bottom were purposively surveyed. No cultural resources were identified during ASM's survey of the property. Conclusions and Management Recommendations The results of records searches conducted for the project were positive in that a number of cultural resources were identified within one mile of the project area. One piece of marine shell and one fragment of large mammal bone were identified during the survey but a close inspection of extensive excavations in the area where these were found did not reveal any further potentially cultural remains. However, a number of large habitation sites are located within a one-mile radius of the project. Due to the heavy leaf litter and the presence of large archaeological sites in the vicinity, archaeological monitoring in the eucalyptus grove located in the northwest portion of the project is recommended. This includes the area located on the west side of El Camino Real from the intersection of El Camino Real and Chestnut A venue and extending south to the frrst residential development located south of this intersection.

Project Location The El Camino Real Widening Project (Project) area is located in the northeastern part of the City of Carlsbad, California. The project extends approximately 4,600 feet or 0.87 miles from Tamarack Avenue in the southeast to Chestnut Avenue in the north. The Project lies within the Habitat Management Plan for Natural Communities in the City of Carlsbad (HMP) plan area. : i j.: - - - - - - Streambed Alteration Agreement for El Camino Real Widening; Tamarack Avenue to Chestnut Avenue SAA 1600-2008-0365-RS Page 3 of 8 Project Description The Applicant proposes to alter the stream/lake to widen the section of El Camino Real from Tamarack Avenue north to Chestnut Avenue to its fufl width of six travel lanes. The Project will widen the roadway to a total width of 126 feet including 8-foot wide bike lanes on both sides of the street, three southbound lanes of 12-foot width each, an 18-foot wide landscaped median Island, and three northbound lanes of 12-foot width each at the southern and northern ends of the Project. In the middle section of the roadway, the roadway would transition between the previously discussed typical section to a modified width of 116 feet including a 6 ½ foot bike lane on the west side of the roadway, three southbound lanes of 12 feet width each, a 14-foot- wide landscaped median island, three northbound lanes of 11 ½ feet width each, and a five-foot bike lane on the east side of the roadway. Parkways consisting of 5 ½ feet of sidewalk and 4 ½ feet of native vegetation (including bio-swale) would be provided on each side of the roadway resulting in a right-of-way width of 116 feet in this reach of the roadway. The Project proposes to keep the existing vertical profile of the road. The Project also includes improvements to the intersection of El Camino Real and Chestnut Avenue; replacement or improvement of storm drains; placement of erosion protection and/or construction of check dams; construction of 12-to 24-inch-deep brow ditches along the west side of Et Camino Real; installation of lighting at 300-foot intervals along both sides of El Camino Real; construction of retaining walls; and relocation of an existing bus stop. Existing overhead power lines along the west side of El Camino Real may be undergrounded. Impacts 1. The Applicant shall not permanently impact more than 0.07 acre of unnamed tributaries to Agua Hedionda. Compensato!'Y Mitigation 2. Mitigation will be conducted through the purchase of mitigation credits from the North County Habitat Bank (NCHB) as follows: a. The Applicant shall mitigate for permanent impacts to 0.03 acre of ephemeral and intermittent unvegetated stream channels through: a) creation/restoration of 0.03-acre of southern willow scrub mixed with freshwater marsh (i.e., 0.03-acre USACE wetland creation/restoration credits) and; b) 0.03-acre riparian enhancement (i.e., 0.03-acre CDFG riparian enhancement credits); b. The Applicant shall mitigate for permanent impacts to 0.04 acre of southern willow scrub (including disturbed) through creation/restoration of 0.04-acre southern willow scrub (i.e .. 0.04-acre of wetland CDFG creation/restoration credits). 3. The Applicant shall mitigate at a minimum 5:1 ratio for impacts beyond those authorized in this Agreement. In the event that additional mitigation is required1 the type of mitigation shall be determined by the Department and may include creation, restoration, or enhancement.

In the event that the project scope, nature, or environmental impact is altered by subsequent permit conditions by a local, state or federal regulatory authority, the Applicant shall either submit an Amendment request or re-Notify the Department of any project modification which conflicts with current conditions or project description. Resource Protection 9. The Applicant shall not remove vegetation within the stream from February 15 to September 15 to avoid nesting birds. However, the Applicant may remove vegetation during this time period if a Department approved biologist conducts a survey for nesting birds within three days prior to VE~getation removal, and ensures no nesting birds shall be impacted by the vegetation removal activity. If an active nest is found, a minimum of a 100-foot activity exclusion zone (buffer) will be established and maintained during the period the nest is active. Applicant may consult with the Department to discuss a reduced buffer size if species sensitivity and localized conditions (e.g., width and type of screening vegetation between the nest and the proposed activity, terrain, existing level of human activity within the buffer and in the surrounding area) warrant a reduced buffer. If the nest is of a bird species is in the orders of Falconiformes or Strigiformes, the exclusion zone will be 500 feet. To avoid a violation of California Fish and Game Code Section 3503.5, the Applicant shall have a Department approved biologist inspect vegetation prior to removal or modification for active nesting of species in the orders of Falconiformes and Strigiformes during all periods these species are documented nesting in southern California. The Applicant - - - - Streambed Alteration Agreement for El Camino Real Widening; Tamarack Avenue to Chestnut Avenue SAA 1600-2008-0365-RS Page 5 of 8 shall submit the mapped survey results to the Department for review and approval prior to vegetation removal or modification to ensure full avoidance measures are in place. 10. Any construction corridor shall be established in such a manner that it avoids disturbance to woody vegetation to the greatest extent possible. Flagging or stakes shall be used to establish the construction corridor. Vegetation shall not be removed or intentionally damaged beyond the construction corridor. Vegetation within this construction corridor which proves to be an obstruction to normal operations but does not need to be removed shall be trimmed to near ground level. 11. No equipment shall be operated within the drip line of oaks. Protective fencing shall be placed around the drip lines of oaks to prevent compaction of the root zone. 12. The Applicant shall use temporary construction fencing to identify the agreed limits of disturbance within the stream and adjacent habitat, and shall have a Department approved biologist oversee fence installation. 13. If a stream's low flow channel, bed or banks have been altered, other than those areas identified as permanent impact, these shall be returned as nearly as possible to their original configuration and width, without creating future erosion problems. 14. This SAA does not authorize the take of any candidate species or species listed as threatened or endangered under the California Endangered Species Act ("CESA") (Fish & Game Code, §2050 et seq.) unless as otherwise specified under the City 9f Carlsbad's Multiple Habitat Conservation Plan.
