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 performance 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 California whom the Bidder proposes to specially fabricate and install any portion of the work or improvement 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 Subcontractor-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.

ITEM NO. 4: QUESTIONS AND ANSWERS Questions relating to the project must go directly to the City’s Public Works Contract Administration Division. The City is not responsible for any information obtained through other means. 1. Is Builders Risk coverage required? If yes, are earthquake and/or flood required? Builders Risk is not required for this project. An overview of the insurance requirements can be found on page 25 of the bid documents. More detailed information can be found on pages 32-34. 2. Will Excess Liability coverage be accepted in addition to the primary Automobile and General Liability limits in order to meet the $2M CSL Automobile liability and $2M per occurrence General Liability limits? Yes. 3. The spec calls out that permits for "SDAPCD regulation in addition to CARB requirements." will be required, but the bypass pumps will not be located in a facility location, and they will not be used to "perform the function of permitted stationary equipment", so CARB only should be acceptable? Correct, the portable pumps to be furnished by the Contractor will be used to support the temporary by-pass of gravity sewer segments. The pumps will not be used to support the lift station and therefore, are not considered “stationary equipment” by definition. Registration under the CARB Statewide Portable Equipment Registration Program (PERP) is acceptable for operation of non-road diesel engines, such as generators, compressors, pumps, hydro blasters, etc., that are greater than 49 hp. 4. For removing the existing T-Lock in the 16 manholes on Bid Schedule B, will the Contractor be allowed to leave the embedded T's in the concrete and remortar over them? Yes. The T-Lock liner shall be removed in full with any embedded Ts or anchorage cut and ground down to match the existing surface. 5. Do the existing manholes in Poinsettia Lane have T-Lock lining that will need to be removed? No. 6. Bressi Sewer Manhole Schedule ( Fuerte Street/Shopping Center)- Just wanted to confirm that some of the manholes on that list will require replacing the bench and channel even though they don’t have any pipe connections? For clarification, all manhole structures in the schedule have 6 to 8-inch inlet and outlet connections. The service lateral connections occur on the pipe run between the structures. The channels and benches scheduled for replacement are in poor condition and require replacement in part of the structure rehabilitation. The replaced channel/bench section shall be from the invert pipe elevation up to the top of the bench throughout the entire structure with the channel formed to match the inlet/outlet diameters.

Just want to confirm that per the pavement grind and overlay per GS-26 will be 3”, and that the grind and overlay will be lane #1 only. Correct. 8. Also, regarding the grind and overlay. There is detail on sheet 2 of the plans that shows a street section with lane #1 width as 10.5’. Carlsbad GS-26 drawing shows a minimum grind width of 12’. Can we use the 10.5’ grind width? The surface course of the pavement restoration (grind/overlay lift) will be limited to the width of the No. 1 lane, (10.5-ft). 9. Can the bid date be extended not only because of the holidays but once I get my dewatering price I will need to find out where the wells are going to be placed, which will also bring up questions. If the wells are in the decorative median (Do we have to go to the nearest joint for a 24”x24” well? That will get expensive). Or if it’s in the pavement, what will be the Limits of paving, grind & overlay for the wells? See Item 1 of this addendum for the bid extension date. Decorative concrete median shall be replaced to the nearest joint per city standard. Typical sections are 15-ft (long) with varying widths shown per plan. Limits of asphalt restoration for well points will vary per City Standard Drawings series GS 25- 29 depending on the trench/diameter width. GS-29 appears most consistent with asphalt restoration associated with well points, however, trench/diameter widths exceeding 8-inches will require asphalt restoration per GS-25.

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 cannot 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 computed on the basis of Extra Work per Section 3-3. 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.

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 compensation 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 equipment 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. Nondirect labor costs, including superintendence, shall be considered part of the markup of Section 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” published 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 incidentals. 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 Contractor 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 recommended by the manufacturer.

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 Contractor 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. 3-3.2.3 Markup. (a) Work by Contractor. 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 Subcontractor, 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 subcontracted 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 documents 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 through the Contractor. The report shall: 1. Show names of workers, classifications, and hours worked. 2.

Subsurface or latent physical conditions differing materially from those represented in the Contract Documents; 2. Unknown physical conditions of an unusual nature differing materially from those ordinarily encountered and generally recognized as inherent in work of the character being performed; and 3. Material differing from that represented in the Contract which the Contractor believes may be hazardous waste, as defined in Section 25117 of the Health and Safety Code, that is required to be removed to a Class I, Class II, or Class III disposal site in accordance with provisions of existing law. 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 performance 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 happening 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 before 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 particular circumstances giving rise to the potential claim, the reasons for which the Contractor believes 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 conditions.

The Contractor shall submit substantiation of its actual costs to the Engineer within 20 working days after the affected work is completed. Failure to do so shall be sufficient cause for denial of any claim subsequently filed on the basis of said notice of potential claim. It is the intention of this section that differences between the parties arising under and by virtue of the contract be brought to the attention of the Engineer at the earliest possible time in order that such matters be settled, if possible, or other appropriate action promptly taken. 3-5 DISPUTED WORK. The Contractor shall give the Agency written notice of potential claim prior to commencing any disputed work. Failure to give said notice shall constitute a waiver of all claims in connection therewith.

When additional information or a meeting is requested, the City will provide its position within 10 working days of receipt of said additional information or Contractor’s presentation of its report. The Contractor may appeal each level’s position up to the City Manager after which the Contractor may proceed under the provisions of the Public Contract Code.

Unless otherwise specified, inspection is required at the source for such typical materials and fabricated items as bituminous paving mixtures, structural concrete, metal fabrication, metal casting, welding, concrete pipe manufacture, protective coating application, and similar shop or plant operations. Steel pipe in sizes less than 6 inches and vitrified clay and cast-iron pipe in all sizes are acceptable upon certification as to compliance with the Specifications, subject to sampling and testing by the Agency. Standard items of equipment such as electric motors, conveyors, elevators, plumbing fixtures, etc., are subject to inspection at the job site only. Special items of equipment such as designed electrical panel boards, large pumps, sewage plant equipment, etc., are subject to inspection at the source, normally only for performance testing. The Specifications may require inspection at the source for other items not typical of those listed in this section. The Contractor shall provide the Engineer free and safe access to any and all parts of work at any time. Such free and safe access shall include means of safe access and egress, ventilation, lighting, shoring, dewatering and all elements pertaining to the safety of persons as contained in Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 78 of 151 the State of California, California Code of Regulations, Title 8, Industrial Relations, Chapter 4, Division of Industrial Safety, Subchapter 4, Construction Safety Orders and such other safety regulations as may apply. Contractor shall furnish Engineer with such information as may be necessary to keep the Engineer fully informed regarding progress and manner of work and character of materials. Inspection or testing of the whole or any portion of the work or materials incorporated in the work shall not relieve Contractor from any obligation to fulfill this Contract. 4-1.3.2 Inspection of Materials Not Locally Produced. When the Contractor intends to purchase materials, fabricated products, or equipment from sources located more than 50 miles outside 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, equipment or process. This approval shall be obtained before producing any material or equipment. 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 expense, shall deliver the materials for testing to the place and at the time designated by the Engineer. 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 is sent so far in advance that the materials on hand at the time will not last but will be replaced by 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 requirements 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 unacceptable at any time, the Contractor shall Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 79 of 151 furnish approved material from other approved sources. If any product proves unacceptable after improper 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 Engineer 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 Specifications 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. 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 material, 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 durability, finish, efficiency, dimensions, service, and suitability are such that the item will fulfill its intended 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, appearance, 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 proportioning 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. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 80 of 151 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 Regulations pertaining to weighing devices. A certificate of compliance shall be presented, prior to operation, 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 operating 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. 4-1.8 Calibration of Testing Equipment. Testing equipment, such as, but not limited to pressure 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. Calibration 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 Modified 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 defined 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 investigation 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 information 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 cooperative investigation concluded. Whenever the cooperative investigation is unable to reach resolution, the investigation may then either conclude without resolution or continue by written notification of one party to the other requesting the implementation of a resolution process by committee. 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 acknowledgement, 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 each 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 Contractor 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 cooperative 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 Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 81 of 151 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 investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation substantiate a contradiction without assignable cause, the investigation 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 pertaining to the contradiction shall be suspended until the investigation is concluded. 4-2 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 Contractor 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 materials 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. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 82 of 151 SECTION 5 – UTILITIES 5-1 LOCATION. The Agency and affected utility companies have, by a search of known records, endeavored to locate and indicate on the Plans, all utilities which are known to exist within the limits of the work. However, the accuracy and/or completeness of the nature, size and/or location of utilities indicated on the Plans is not guaranteed. Where underground main distribution conduits such as water, gas, sewer, electric power, telephone, or cable television are shown on the Plans, the Contractor shall assume that every property 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 (Underground 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. Prior to pipeline excavation, the Contractor shall determine, by potholing, the locations and depths of all utilities which are shown on the Contract Documents or have been marked by the utility owners and which may affect or be affected by its operations. The Contractor shall pothole all service connections, utilities that cross or parallel (within 5 feet) the proposed construction, and all connection points to existing utilities. The Contractor shall record the material size (outside diameter), type, and horizontal and vertical locations (bearing and slope) and submit the data and allow time for the Engineer’s review in accordance with Section 2-5.3. If no separate bid item is provided in the Contract for potholing, full compensation for such work shall be considered included in the bid item of work requiring the potholing and no separate payment shall be made therefor. 5-2 PROTECTION. The Contractor shall not interrupt the service function or disturb the support 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: Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 83 of 151 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 protection 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 procedures required to maintain or restore the integrity of the system. 5-3 REMOVAL. Unless otherwise specified, the Contractor shall remove all interfering portions 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. The costs involved in the removal and disposal shall be considered incidental to the bid items of work necessitating such removals and no separate payment shall be made therefor, unless a bid item for “Removal” is specifically included in the bid proposal. 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 before 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 manhole frame and cover sets to be brought to grade as directed and approved by the City. 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. 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 property 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 interfering service connections. The Agency will not be involved in any such agreement. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 84 of 151 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 compensation will be allowed therefore or for additional work, materials or delay associated with the temporary omission. The portion thus omitted shall be constructed by the Contractor immediately following the relocation of the utility involved unless otherwise directed by the Engineer. 5-5 DELAYS. 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 available 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 Section 5-1. The Contractor may be given an extension of time for unforeseen delays attributable to unreasonably 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 identified 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 alterations 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. 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. Cooperation with CMWD and City staff will be required for all work affecting existing utility systems or facilities and prior to water utility shutdowns, sewer bypass operations, testing and inspections, and project completion. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 85 of 151 SECTION 6 – PROSECUTION, PROGRESS, AND ACCEPTANCE OF THE WORK 6-1 CONSTRUCTION SCHEDULE AND COMMENCEMENT OF WORK. Except as otherwise provided herein and unless otherwise prohibited by permits from other agencies as may be required by law the Contractor shall begin work within ten (10) calendar days after receipt of the "Notice to Proceed". 6-1.1 Pre-Construction Meeting. After, or upon, notification of contract award, the Engineer will set the time and location for the Preconstruction Meeting. Attendance of the Contractor’s management personnel responsible for the management, administration, and execution of the project is mandatory for the meeting to be convened. Failure of the Contractor to have the Contractor’s responsible project personnel attend the Preconstruction Meeting will be grounds for default by Contractor per Section 6-4. No separate payment will be made for the Contractor’s attendance at the meeting. The notice to proceed will only be issued on or after the completion of the preconstruction meeting. 6-1.1.1 Baseline Construction Schedule. The Contractor shall prepare the Baseline Construction Schedule as a Critical Path Method (CPM) Schedule in the precedence diagram method (activity-on-node) format and submit the schedule in accordance with 2-5.3. The schedule shall: A. Be prepared using a commercially available, Windows compatible software program, “Suretrak” by Primavera or “Project” by Microsoft Corporation or approved equal. B. Be prepared in hard copy (paper) and electronic (Adobe PDF) format and free of file locking, encryption or any other protocol that would impede full access to the data and labeled with the project name and number, the Contractor’s name and the date of preparation. C. Begin with the date projected for the Notice to Proceed and conclude with the date of final completion conforming with the Contract time. D. Depict a time-scaled network diagram of all activities, logic relationships of interdependent activities, and milestones comprising the complete period of Work with tasks on the vertical axis and their durations on the horizontal axis. Use distinctive texture patterns or line types to show the critical path within the Contract time. Include a tabular listing of each activity and its identification number, description, duration, early start, early finish, late start, late finish, total float, and all predecessor and successor activities. The number of activities will communicate the Contractor’s plan for project execution, accurately describe the project work and allow monitoring and evaluation of progress and time impacts. Activity descriptions shall accurately define the work planned for the activity. Activity durations shall not be shorter than 1 working day or longer than 15 working days unless approved by the Engineer. E. Include detail of all project phasing, staging and sequencing including all milestones necessary to define beginning and ending of each phase or stage and constraints which may impact any activity. Include time allowances for coordination with utility companies and other agencies, equipment and material deliveries, submittal reviews and approvals, Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 86 of 151 traffic control setup and phasing, Work performed by others, inspections, testing and commissioning, corrective work, and any non-work periods. Float or slack time within the schedule is available without charge or compensation to whatever party or contingency first exhausts it. A schedule which shows a project duration longer than the Contract Time will not be acceptable and will be grounds to consider the Contractor in default of the Contract per 6-4. The Engineer may choose to accept the Contractor’s proposal of a project duration which is shorter than the Contract time provided the shortened Baseline Construction Schedule is reasonable and demonstrates, to the satisfaction of the Engineer, that the Agency and all other entities, public and private, which interface with the project are able to support the provisions of the shortened schedule. Acceptance of a shortened Baseline Construction Schedule will be confirmed through the execution of a Change Order revising the Contract time. The Engineer’s approval of the Baseline Construction Schedule is a condition precedent to issuance of the Notice to Proceed. If the schedule does not meet the requirements of these specifications, the Contractor shall revise the schedule and resubmit it to the Engineer. Failure to obtain the Engineer’s approval of the schedule within fifteen (15) working days after the date of the preconstruction meeting shall be grounds to consider the Contractor in default of the Contract per 6-4. The number of working days used by the Engineer to review the initial Baseline Construction Schedule submittal will not be included in the 15 working days. The Engineer shall complete subsequent reviews of the revised schedule and progress updates within 5 working days of receipt. The Engineer’s response to each review will consist of one of the following: “Accepted.” The Contractor may proceed with the Work upon issuance of the Notice to Proceed. Payment for the schedule may be requested by the Contractor. “Accepted with Comments.” The Contractor may proceed with the Work upon issuance of the Notice to Proceed. The Contractor must revise and resubmit the schedule and receive the Engineer’s acceptance of the schedule before payment for the schedule is requested by the Contractor. “Not Accepted.” The Contractor may not proceed with the Work, must revise and resubmit the schedule and may not request payment for the schedule. 6-1.1.2 Schedule Updates and Revisions. The Contractor shall meet with the Engineer during the last week of each month to agree upon the completion level of each activity as a basis for progress payments. Schedule updates shall conform with the requirements for the initial submittal in 6-1.1.1 and shall: A. Show the actual dates of each activity start and/or finish during the month. The schedule update shall include specific notation for any changes in actual dates after they are first reported. B. Report the percent complete for each activity in progress at the end of the month as determined by the Engineer. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 Revised 6/15/17 Contract Nos. 5503-26 and 5548-D Page 87 of 151 C. Include a list and explanation of all changes made to the activities, dates or interconnecting logic. D. Include activity and network revisions reflecting the Change Orders approved in the previous month as agreed upon during the review and acceptance of the Change Orders. The Engineer’s responses to the progress schedule updates shall be as described in 6-1.1.1. The Contractor shall proceed with Work and request payment for the progress schedule updates as described therein. If the Contractor fails to submit the progress schedule updates as required herein, the Contractor may elect to proceed with the Work at its own risk and shall forfeit payment for the progress schedule update until compliance is met. If the Contractor elects to delay or cease Work after failure to submit the progress schedule updates, any resulting delay, impact, or disruption to the Work will be the Contractor’s responsibility. 6-1.1.3 Interim Revisions. Should the actual or projected progress of the Work exceed 5 percent of the Contract Time, the Contractor shall prepare and submit a revised Baseline Construction Schedule independently of and prior to the next progress schedule update with a list and explanation of each change made to the schedule. The submittal, schedule review and acceptance requirements of 6-1.1.2 shall apply, 6-1.1.4 Late Completion or Milestone Dates. If a schedule update indicates a completion date later than the Contract time or contractually required milestone completion date, the Agency may withhold Liquidated Damages for the number of days late. Should a subsequent schedule update which removes all or a portion of the delay be “Accepted” by the Engineer, all or the allocated portion of the previously held Liquidated Damages shall be released in the monthly payment to the Contractor immediately following such acceptance. 6-1.1.5 Final Schedule Update. The Contractor shall prepare and submit a final schedule update when one hundred percent of the Work is completed. The update must accurately represent the actual dates for all activities. The final schedule update shall be prepared and reviewed in accordance with 6-1.1.2. Acceptance of the final schedule update is required for release of funds retained per 9-3.2. 6-1.1.6 Three-Week Look Ahead Schedules. The Contractor shall submit a detailed 3-week look ahead schedule prior to each progress meeting throughout project duration. The schedules shall be revised weekly to identify the construction activities and durations for each bid item of work for the current week and the succeeding two weeks. The Contractor shall revise the schedule to include additional activities or actual progress when so requested by the Engineer. 6-1.1.7 Measurement and Payment. The Contractor’s preparation, revision and maintenance of the Construction Schedule are incidental to the Work and no separate payment will be made therefor. 6-2 PROSECUTION OF WORK. To minimize public inconvenience and possible hazard and to restore street and other work areas to their original condition and state of usefulness as soon as practicable, the Contractor shall diligently prosecute the Work to completion. If the Engineer determines that the Contractor is failing to prosecute the Work to the proper extent, the Contractor shall, upon orders from the Engineer, immediately take steps to remedy the situation.

The purpose of this evaluation was to explore the subsurface conditions along the utility alignment and to provide geotechnical recommendations for the design and construction of the project. Our scope of work also includes ongoing monitoring of the groundwater depth along the alignment. This report presents the results of our field exploration, geotechnical laboratory testing, analytical laboratory testing, and preliminary groundwater monitoring results, as well as our conclusions regarding the geotechnical conditions at the site and our recommendations for the design and construction of this project. 2 SCOPE OF SERVICES The scope of services for this evaluation included the following: • Reviewing background information, including geologic and fault maps, topographic maps, groundwater data, and available published and in-house geotechnical literature pertaining to the project area. • Performing a site reconnaissance to observe the existing site conditions and to mark our boring locations for utility clearance by Underground Service Alert (USA). • Preparing a Site-Specific Health and Safety Plan including recommended levels of personnel protective equipment based on field screening levels and other general health and safety considerations for field personnel. • Preparing a traffic control plan and obtaining a traffic control permit for areas where exploratory borings were performed. Traffic control was implemented during the performance of our fieldwork. • Obtaining Right-of-Way and traffic control permits from the City of Carlsbad for the well installation. • Obtaining a monitoring well installation permit from the County of San Diego Department of Environmental Health and Quality (DEHQ) prior to the performance of our subsurface exploration. • Performing a subsurface exploration consisting of the drilling, sampling, and logging of two small-diameter borings using a truck mounted drill rig to depths up to approximately 31.5 feet. Bulk and in-place samples were obtained at selected intervals from the borings. The soil samples were transported to our in-house geotechnical laboratory for testing. • Converting the borings into groundwater monitoring wells to monitor groundwater levels, perform slug testing, and perform groundwater sampling and analytical testing. The groundwater monitoring wells were constructed with a traffic rated well cover and 2-inch diameter Schedule 40 PVC well casing in each boring.

Surface topography along the project alignment ranges from approximately 111 feet above mean sea level (MSL) at the west end of the alignment to approximately 168 feet above MSL at the east end of the alignment. The global site coordinates within the central portion of the project alignment is approximately 33.1166°N Latitude and -117.2545°W Longitude Based on the provided information, the existing sewer will be replaced along Poinsettia Lane near its intersections with El Fuerte Street and Alicante Road. We understand that possible construction methods for the new pipeline will be conventional, open trench techniques. 4 SUBSURFACE EXPLORATION Our subsurface exploration was performed on August 4 and 5, 2025 and consisted of the drilling, logging, and sampling of two small-diameter borings (B-1 and B-2). Prior to commencing the subsurface exploration, USA was notified to markout the existing utilities. The purpose of the borings was to evaluate subsurface conditions and to collect samples for geotechnical laboratory testing. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 3 The borings were drilled to depths up to approximately 31.5 feet using a truck mounted drill rig equipped with 8-inch diameter hollow-stem augers. The borings were logged and sampled by Ninyo & Moore personnel. Representative bulk and relatively undisturbed soil samples were obtained at selected depths within the borings and were then transported to our in-house geotechnical laboratory for analysis. Driven samples were collected at varying depths using the modified split-barrel drive samplers in general accordance with ASTM D 3550. The samplers were driven into the ground with a 140-pound hammer free-falling from a height of 30 inches. The blow counts were recorded for every 6 inches of penetration and are presented on the boring logs in Appendix A. For comparison, the blow counts for the modified split-barrel drive sampler should be corrected to equivalent SPT values using 60 percent for samplers driven into granular soils and 80 percent for samplers driven into clayey soils. The boring locations are presented on Figure 2. Following drilling, the two borings were converted into groundwater monitoring wells MW-1 and MW-2 (Figure 2) to monitor groundwater levels, perform slug testing, and perform groundwater sampling and analytical testing. The groundwater monitoring wells were constructed with a traffic rated well cover and 2-inch diameter Schedule 40 PVC well casing in each boring (See Figures A-5 and A-6). 5 GEOTECHNICAL LABORATORY TESTING Geotechnical laboratory testing of representative soil samples collected from our subsurface exploration included tests to evaluate in-situ dry density and moisture content, sieve (gradation) analysis, shear strength, and soil corrosivity. The results of the in-situ dry density and moisture content tests are presented at the corresponding depths on the boring logs presented in Appendix A. The results of the other laboratory tests and a description of the test methods used are presented in Appendix B. 6 GROUNDWATER SAMPLING Groundwater samples were collected from groundwater monitoring wells MW-1 and MW-2 (Figure 2) and analyzed for requirements to obtain a Special Use Discharge Permit from the Encina Wastewater Authority (EWA). As part of the sewer pipeline replacement project, groundwater will need to be pumped from the site and discharged into the sewer under the purview of the EWA. On August 12, 2025 Ninyo & Moore collected groundwater samples from monitoring wells MW-1 and MW-2 (Figure 2) by low-flow sampling methodology. After gauging groundwater elevations, Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 4 the monitoring wells were purged using low-flow, minimal drawdown procedures. A bladder pump fitted with dedicated Teflon-lined tubing was slowly lowered to the desired depth, at approximately the middle of the screen interval, and the well was allowed to equilibrate for a minimum of one hour prior to purging. The monitoring wells were purged at rates to achieve minimal drawdown. The purged water was monitored at three- to five-minute intervals for temperature, pH, specific conductance, dissolved oxygen (DO), oxidation-reduction potential (ORP), and turbidity, using an in-line flow cell. When water quality parameters stabilized, laboratory-supplied sample containers were immediately filled from the dedicated discharge line without disturbing the pump or flow rate. Sampling data was documented on monitoring well summary forms, which include the sampler’s name, monitoring well identification, stabilization parameters, purge rate, and date and time the sample was collected. These summary forms are included in Appendix C. 7 GROUNDWATER ANALYTICAL RESULTS The collected groundwater samples were submitted to a California-accredited analytical testing laboratory. Groundwater samples were analyzed based on Local Discharge Limits for users in the Encina Water Authority Pollution Control Facility’s service area (EWAPCF) (Appendix D). Groundwater analytical results were compared to the EWAPCF’s daily maximum limits and included in the attached Tables 1 through 3. Total Recoverable Metals are listed in Table 1, Total toxic organics are listed in Table 2, and all other constituents are listed in Table 3. Analytical results are provided in Appendix E and summarized below. 7.1 Total Recoverable Metals Total recoverable metals were analyzed by United States Environmental Protection Agency (EPA) method 200.7. All total recoverable metal concentrations are below the EWA local discharge limits.

According to EWA’s Pretreatment Ordinance, total toxic organics (TTO) is “the summation of all quantifiable values greater than 0.01 milligrams per liter (mg/L) for the organics regulated by the EPA for a specific industrial category or by EWA”. The only constituent analyzed with a concentration greater than 0.01 mg/L was diethyl phthalate in MW-1 at a concentration of 0.012 mg/L. Therefore, the TTO for MW-1 is 0.12 mg/L, below the EWA local discharge limit of 2.00 mg/L. All constituents analyzed in MW-2 were below 0.01 mg/L and therefore the TTO in MW-2 is 0.00 mg/L. The laboratory method detection limits (MDLs) for all analytes were below 0.01 mg/L indicating that analytes not detected below the MDL are also below the TTO calculation threshold.

Concentrations were detected in MW-1 and MW-2 at concentrations of 1.53 mg/L and 0.86 mg/l, respectively. Both concentrations are below the EWA local discharge limit of 400 mg/L. 7.4 Biochemical Oxygen Demand Biochemical Oxygen Demand (BOD) was analyzed in accordance with EPA method SM 5210B. The EWA local discharge limit is 500 lbs/day. BOD concentrations (mg/L) were converted to lbs/day assuming continuous discharge to the EWA sewer system over a 24-hour period at a flow rate of 5 gallons per minute at each well location (Table 3). For monitoring well MW-1, the measured BOD concentration was 1.56 mg/L, corresponding to approximately 0.09 lbs/day. For MW-2, the BOD concentration was not detected at or above the laboratory reporting limit of 1.0 mg/L. The report limit concentration of 1 mg/L was used in the conversion which equates to approximately 2.12 lbs/day. Note that the discharge flow rate required for groundwater drawdown required for the pipeline project are unknow at this time.

The EWA local discharge limit is 500 lbs/day. TSS concentrations (mg/L) were converted to lbs/day assuming continuous discharge to the EWA sewer system over a 24-hour period at a flow rate of 5 gallons per minute at each well location (Table 3). For monitoring well MW-1, the measured TSS concentration was 100 mg/L, corresponding to approximately 6 lbs/day. For MW-2, the TSS concentration was 35.3 mg/L, which equates to approximately 2.12 lbs/day. Note that the discharge flow rate required for groundwater drawdown required for the pipeline project are unknow at this time. 7.6 Total Dissolved Solids Total dissolved solids (TDS) was analyzed in accordance with EPA method SM 2540C. TDS is not included in EWA local discharge limit list but was requested by EWA in email communications with Ninyo & Moore. Concentrations of TDS in MW-1 and MW-2 are 8,790 mg/L and 3,290 mg/L, respectively. 7.7 Temperature and pH Temperature and pH were measured in the field during the groundwater low-flow sampling and recorded on field data sheets (Appendix A). Both temperature and pH were within the EWA local discharge limit ranges.

Additionally, Ninyo & Moore performed aquifer testing of the wells, the output of which was analyzed by Ninyo & Moore using the hydrogeologic platform AQTESOLV. The estimated hydraulic conductivity values ranged from 0.38 feet per day (ft/d) for the later portion of the curve to 3.4 ft/d for the early portion of the curve. For this study, Ninyo & Moore used the higher, more conservative, hydraulic conductivity estimate in the groundwater model. Table 1 below presents the model design data derived from field measurements and review of the available Aquatic Center conceptual test fit drawing: Table 4 – Dewatering Target Elevation Data Parameter Description Model Input MW-1 and MW-2 Elevation* 113’ / 168' AMSL MW-1/MW-2 Depth to Groundwater 11' / 27’ MW-1/MW-2 Groundwater Elevation 102' / 141’ AMSL Presumed Pipe Invert Elevation** 99’ / 156' AMSL Target Dewatering Elevation*** 96' / 156’ AMSL Target Dewatering Drawdown 6' to NA Hydraulic Conductivity Estimate Low 0.43 ft/day Hydraulic Conductivity Estimate High 3.4 ft/day Note: * Extrapolated from geotechnical borings B-1 and B-2. **Estimated, presently unknown. ***Includes 3' safety factor. AMSL – above mean sea level (NAVD 88); all elevations are approximate. 9 GROUNDWATER MODEL DESIGN AND OUTPUT For the purpose of this study, the model assumes a target dewatering elevation of approximately 6 feet below the measured static water elevation in MW-1 for the eastern portion of the project alignment. Due to the east-to-west topographic gradient, Ninyo & Moore assumes that no dewatering will be necessary for the eastern portion of the alignment. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 9 The groundwater model processing platform, Groundwater Vistas, was utilized to create groundwater simulations utilizing the Modflow method (2007). A computerized finite difference groundwater model was set out on a grid with uniform 10-foot row and column spacing over an area of 5,280 feet wide and 5,280 feet long centered on the project Site. The model assumes that homogeneous and isotropic aquifer conditions exist horizontally across the grid. The model was designed to estimate the approximate number and configuration of wells expected to dewater an approximately 5-foot wide by 500-foot long excavation to the target dewatering elevation of approximately 96 feet AMSL. The model was run until steady-state groundwater conditions were achieved. Modelling data included in Appendix F presents a screen image of the formatted test data and plotted graphs, aquifer testing data analysis output, and model output static and pumping contours and profiles. The model simulates the effect of 11 dewatering wells pumping at a combined flow rate of 55 gallons per minute (gpm), i.e., 5 gpm/dewatering well along a 500-footeast-west oriented trench on the eastern portion of the alignment near MW-1. Based on this information, it appears that the Site can be adequately dewatered by a network of 11 dewatering wells pumping simultaneously during construction activities. Ninyo & Moore assumes that no more than 500 feet of excavation will be open at a given time, and that additional dewatering wells will be installed to the east along the alignment as necessary following completion of each preceding trench. However, more dewatering wells may be needed, depending on the actual size, depth, and configuration of the planned improvements. The target dewatering elevation between dewatering wells should be achieved within 7 to 10 days of continuous pumping. The dewatering contractor should plan accordingly to avoid unnecessary delays. 10 GEOLOGIC AND SUBSURFACE CONDITIONS Our findings regarding regional and site geology at the project alignment are provided in the following sections. 10.1 Site Geology The project alignment is mapped as being underlain by young alluvial floodplain deposits (Kennedy and Tan, 2007), as shown on Figure 3. Geologic units encountered during our subsurface exploration included fill and alluvium. Generalized descriptions of the earth units encountered during our field reconnaissance and subsurface exploration are provided in the subsequent sections. Additional descriptions of the subsurface units are provided on the logs of the borings in Appendix A. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 10 10.1.1 Fill Fill material was encountered in each of our exploratory borings underlying the surface hardscaping and extended to depths ranging from approximately 10 to 21 feet. As encountered, the fill material consisted of various shades of brown and gray, dry to moist, loose to very dense, and clayey sand. Scattered amounts of gravel were encountered within the fill soils. Documentation regarding fill placement was not available for our review. 10.1.2 Alluvium Alluvial materials were encountered in our exploratory borings underlying the fill soils in each of our borings and extended to the total depths explored. As encountered, the alluvium consisted of various shades of black, brown and gray, moist to wet, loose to medium dense, clayey sand and stiff to very stiff, sandy lean clay. 10.2 Groundwater Groundwater was encountered in our borings B-1/MW-1 and B-2/MW-2. During the drilling operations, the groundwater was encountered at depths of approximately 18.5 and 28 feet in borings B-1/MW-1 and B-2/MW-2. Subsequent to conversion of the borings into groundwater sampling and monitoring wells, water level data loggers were installed within each of the two groundwater monitoring wells to record depth measurements. Since installation, biweekly visits to record the water level data have been performed. To date, the groundwater depth measurements for B-1/MW-1 indicate groundwater depths ranging from approximately 11.4 to 18.5 feet. To date, the groundwater depth measurements for boring B-2/MW-2 indicate groundwater depths ranging from approximately 26.7 to 28 feet. Groundwater levels can fluctuate due to flood events, seasonal precipitation, variations in ground elevations, subsurface stratification, irrigation, groundwater pumping, storm water infiltration, and other factors. Additionally, perched water conditions may be present at the site due to the presence of trench backfill and bedding materials for underground utilities, as these materials tend to act as a conduit for perched water conditions. 10.3 Faulting and Seismicity Based on our review of the referenced geologic maps and stereoscopic aerial photographs, as well as on our site-specific fault hazard evaluation, the proposed alignment is not underlain by Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 11 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). The alignment is not located within a State of California Earthquake Fault Zone (EFZ) (formerly known as an Alquist-Priolo Special Studies Zone) (Hart and Bryant, 2007). Like the majority of Southern California, the alignment is located in a seismically active area and the potential for strong ground motion is considered significant during the design life of the proposed pipelines. The nearest known active fault is the Rose Canyon fault, located approximately 7 miles west of the alignment (Figure 4). 10.3.1 Surface Ground Rupture Based on our review of the referenced literature and our site reconnaissance, active faults are not known to cross the project vicinity. Therefore, the potential for ground surface rupture due to faulting at the alignment is considered low. However, lurching or cracking of the ground surface as a result of nearby seismic events is possible. 10.3.2 Strong Ground Motion Considering the proximity of the site to active faults capable of producing a maximum moment magnitude of 6.64 or more, the project area has a high potential for experiencing strong ground motion. The 2025 California Building Code (CBC) specifies that the risk-targeted maximum considered earthquake (MCER) ground motion response accelerations be used to evaluate seismic loads for design of buildings and other structures. Based on our review of the CGS shear wave velocity map, the average shear wave velocity in the upper 30 meters (100 feet) of the subsurface profile (VS30) is estimated to be approximately 351 meters per second (1,152 feet per second) (CGS, 2015). In accordance with Chapter 20 of the American Society of Civil Engineers (ASCE) Publication 7-16 (2017) for the Minimum Design Loads and Associated Criteria for Building and Other Structures, the site classification is Site Class D. In accordance with ASCE 7-16, the mapped MCER ground motion response accelerations were determined using the Unified Hazard Tool (web-based). The MCER ground motion response accelerations are based on the spectral response accelerations for 5 percent damping in the direction of maximum horizontal response and incorporate a target risk for structural collapse equivalent to 1 percent in 50 years with deterministic limits. Spectral response acceleration parameters, consistent with the 2022 CBC, are provided in Section 10.2 for the evaluation of seismic loads on buildings and other structures. Seismic Design Considerations Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 12 ASCE 7-16 specifies that the potential for liquefaction and soil strength loss be evaluated, where applicable, for the mapped maximum considered earthquake geometric mean (MCEG) peak ground acceleration adjusted for site effects (PGAM). The MCEG PGAM is based on the geometric mean peak ground acceleration with a 2 percent probability of exceedance in 50 years. The PGAM for the site was calculated as 0.491g using the ASCE 7 Hazard Tool (2025). 10.3.3 Tsunamis Tsunamis are long wavelength seismic sea waves (long compared to the ocean depth) generated by sudden movements of the ocean bottom during submarine earthquakes, landslides, or volcanic activity. Based on the inland location of the alignment, the potential for a tsunami to affect the site is not a design consideration. 10.3.4 Landsliding Landslides, slope failures, and mudflows of earth materials generally occur where slopes are steep and/or the earth materials are too weak to support themselves. The landside map for the alignment indicates that the project area is marginally susceptible to landsliding (Tan, 1995). Based on the relatively level topography along the alignment, the potential for landslides or mudflows to affect the project site is considered low. 11 CONCLUSIONS Based on our review of the referenced background data, subsurface exploration, and laboratory testing, it is our opinion that construction of the proposed project is feasible from a geotechnical standpoint provided the recommendations presented in this report are incorporated into the design and construction of the project. In general, the following conclusions were made: • The proposed alignment is underlain by fill and alluvial materials. • The existing fill and alluvium encountered onsite should be generally excavatable with heavy-duty earth moving equipment in good working condition. • Due to the loose nature of the granular layers of the subsurface and the presence of a shallow groundwater table, the contractor should anticipate encountering caving and/or sloughing conditions when trenching or excavating in these materials. • Soils derived from onsite excavations are generally considered suitable for reuse as trench zone backfill, if needed, provided they are processed to meet the recommendations of this report. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 13 • Groundwater was encountered in our borings B-1/MW-1 and B-2/MW-2. During the drilling operations, the groundwater was encountered at depths of approximately 18.5 and 28 feet in borings B-1/MW-1 and B-2/MW-2. Additionally, periodic groundwater depth measurements for B-1/MW-1 indicate groundwater depths ranging from approximately 11.4 to 18.5 feet. To date, the groundwater depth measurements for boring B-2/MW-2 indicate groundwater depths ranging from approximately 26.7 to 28 feet. Fluctuations in the depth to groundwater may occur due to flood events, seasonal precipitation, variations in ground elevations, subsurface stratification, irrigation, groundwater pumping, storm water infiltration, and other factors. • Based on the results of our geotechnical laboratory testing presented in Appendix B, as compared to the California amended (Caltrans, 2021) corrosion criteria, the onsite soils would be considered corrosive. Consideration should be given to retaining a corrosion consultant to further evaluate the laboratory tests and provide appropriate mitigation recommendations, if warranted. • Based on the groundwater analytical results, concentrations of analytes listed in EWA local discharge limits in groundwater samples are all below the maximum daily limits. BOD and TSS concentrations were converted to pounds per day based on the maximum daily load limit using groundwater discharge assumptions. The discharge requirements to draw down groundwater for the pipeline project are unknown at this time but will be provided in the Groundwater Modeling report based on aquifer pump testing and groundwater elevation monitoring. 12 RECOMMENDATIONS Based on our understanding of the project, the following recommendations are provided for the design and construction of the project. The proposed site improvements should be constructed in accordance with the requirements of the applicable governing agencies. 12.1 Earthwork In general, earthwork should be performed in accordance with the recommendations presented in this report. Ninyo & Moore should be contacted for questions regarding the recommendations or guidelines presented herein. 12.1.1 Site Preparation Prior to performing site excavations, the project alignment should be cleared of vegetation, surface obstructions, rubble and debris, abandoned utilities and foundations, and other deleterious materials. Existing utilities within the project limits, if any, should be re-routed or protected from damage by construction activities. Obstructions that extend below finish grade, if any, should be removed and the resulting holes filled with compacted soils. Materials generated from the clearing operations should be removed from the project site and disposed of at a legal dumpsite. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 14 12.1.2 Excavation Characteristics Based on our subsurface exploration of the site, we anticipate that excavations within materials underlying the alignment should be generally excavatable with heavy-duty earth moving equipment in good working condition. In addition, due to the presence of loose sands and a shallow groundwater, the following ground conditions should be anticipated: Caving soils; Flowing sands; and Sloughing of excavations; Recommendations for shoring and dewatering are presented in the following sections. 12.1.3 Temporary Excavations and Shoring For temporary excavations, we recommend that the following Occupational Safety and Health Administration (OSHA) soil classifications be used: Fill and Alluvium Type C Upon making the excavations, the soil classifications and excavation performance should be evaluated in the field by the geotechnical consultant in accordance with the OSHA regulations. Temporary excavations should be constructed in accordance with OSHA recommendations. For trenches or other excavations, OSHA requirements regarding personnel safety should be met using appropriate shoring (including trench boxes) or by laying back the slopes to no steeper than 1½:1 (horizontal to vertical) in fill and alluvium. Temporary excavations that encounter seepage may be shored or stabilized by placing sandbags or gravel along the base of the seepage zone. Excavations encountering seepage should be evaluated on a case-by-case basis. Onsite safety of personnel is the responsibility of the contractor. We understand a shoring system may be incorporated to support the excavation sidewalls and protect existing utilities during construction. Shoring design parameters are presented below. Particular caution should be used near existing underground utilities. Existing utilities that are located within a zone based on a 1:1 plane projected up from the bottom outside edge of the new trench should be considered at risk. The type of shoring and sequence of shoring installation should be designed to protect utilities and surface improvements. Lateral earth pressures exerted on restrained and cantilevered shoring systems are indicated on Figures 5 and 6, respectively. The recommended design earth pressures are based on the assumptions that: (a) the shoring system is constructed without raising the Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 15 ground surface elevation behind the shoring, (b) there are no surcharge loads, such as soil stockpiles, construction materials, or vehicular traffic, and (c) no loads act above a 1:1 plane extending up and back from the base of the shoring system. For shoring subjected to the above-mentioned surcharge loads, the contractor should include the effect of these loads on lateral earth pressures acting on the shoring wall. Settlement of the ground surface may occur behind the shoring wall system during excavation. The amount of settlement depends on the type of shoring system, the quality of contractor’s workmanship, and soil conditions. Settlement may cause distress to adjacent structures, if present. To reduce the potential for distress to adjacent structures, we recommend that the shoring system be designed to limit the ground settlement behind the shoring to ½ inch or less. Possible causes of settlement that should be addressed include vibration during installation of the sheet piling, excavation for construction, construction vibrations, dewatering, and removal of the support system. We recommend that the potential settlement distress be evaluated carefully by the contractor prior to construction. The contractor should retain a qualified and experienced engineer to design the shoring system. The shoring parameters presented in this report are for preliminary design purposes and the contractor should evaluate the adequacy of these parameters and make appropriate modifications for their design. We recommend that the contractor take appropriate measures to protect workers. OSHA requirements pertaining to worker safety should be observed. We further recommend that the construction methods provided herein be carefully evaluated by a qualified specialty contractor prior to commencement of the construction. 12.1.4 Construction Dewatering Groundwater was encountered during our subsurface exploration at depths as shallow as 18½ feet. Additionally, existing utility trench lines may act as conduits for perched water conditions. The contractor should anticipate implementing dewatering measures to address potential groundwater and seepage. There may be potential for collected onsite water resulting from the seepage to be reused on site during construction for soil compaction, dust control, and other such uses. In the event that groundwater, perched water, and/or seepage conditions are encountered that result in the disposal of groundwater offsite, the disposal of groundwater should be performed in accordance with guidelines of the Regional Water Quality Control Board (RWQCB). Furthermore, as part of the construction process, such dewatering operations should be prepared by the contractor’s engineer and reviewed by the design engineer and consider anticipated drawdown, piping of soils, volume of pumping, potential for settlement, and groundwater discharge. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 16 Pump sizing should be performed by the contractor’s team during construction based on an independent evaluation of the subsurface conditions in the project area. However, the subsurface data (such as the laboratory test gradations and depth to groundwater encountered in the boring logs) presented in this report is intended to present a characterization of the anticipated soil, rock, and groundwater conditions at the time of evaluation. 12.1.5 Excavation Bottom Stability Excavation bottoms for trenches or access pits above the groundwater table are generally anticipated to be stable. However, the bottoms of excavations that extend into or near groundwater may encounter unstable bottom conditions. In general, unstable bottom conditions may be mitigated by overexcavating the excavation bottom an additional 1 to 2 feet, as evaluated in the field by the project geotechnical consultant, and replacing with a layer of compacted ¾- to 1½-inch crushed gravel encased in a non-woven geotextile (e.g., Mirafi® 140N geotextile or an approved equivalent). Recommendations for stabilizing excavation bottoms should be based on evaluation in the field by the geotechnical consultant at the time of construction. 12.1.6 Pipe Bedding and Modulus of Soil Reaction (E’) Although not anticipated, we recommend that pipes constructed using trenching methods be supported on 6 inches or more of granular bedding material. Granular pipe bedding should be provided to distribute vertical loads around the pipe. Bedding material and compaction requirements should be in accordance with this report. Pipe bedding typically consists of graded aggregate with a coefficient of uniformity of three or more. The modulus of soil reaction (E') is used to characterize the stiffness of soil backfill placed at the sides of buried flexible pipes for the purpose of evaluating deflection caused by the weight of the backfill over the pipe (Hartley and Duncan, 1987). A soil reaction modulus of 1,200 pounds per square inch (psi) may be used for an excavation depth of up to about 5 feet when backfilled with granular soil compacted to a relative compaction of 90 percent as evaluated by the ASTM International (ASTM) D 1557. A soil reaction modulus of 1,600 psi may be used for trenches deeper than 5 feet. 12.1.7 Pipe Zone Backfill The pipe zone backfill should be placed on top of the pipe bedding material and extend to 1 foot or more above the top of the pipe in accordance with the recent edition of the Standard Specifications for Public Works Construction (“Greenbook”). Pipe zone backfill Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 17 should have a Sand Equivalent (SE) of 30 or more, and be placed around the sides and top of the pipe. Silts and clays should not be used as pipe zone backfill. Special care should be taken not to allow voids beneath and around the pipe. Compaction of the pipe zone backfill should proceed up both sides of the pipe. It has been our experience that the voids within a crushed rock material are sufficiently large to allow fines to migrate into the voids, thereby creating the potential for sinkholes and depressions to develop at the ground surface. If open graded gravel is utilized as pipe zone backfill, this material should be separated from the adjacent trench sidewalls and overlying trench backfill with a geosynthetic filter fabric, particularly if groundwater is expected. 12.1.8 Trench Zone Backfill Based on our subsurface evaluation, the onsite materials (except for the clayey fill material) should be generally suitable for reuse as trench backfill provided they do not contain rocks or lumps over 3 inches, and not more than 30 percent larger than ¾ inch. Larger chunks, if generated during excavation, may be broken into acceptably sized pieces or disposed of offsite. Additionally, backfill materials should have an organic content of less than approximately 3 percent by volume (or 1 percent by weight), be free of debris, and exhibit an EI of 50 or less (i.e., low expansion potential) as evaluated by ASTM D 4829. Trench backfill should be moisture-conditioned to generally at or slightly above the laboratory optimum. Trench backfill should be compacted to a relative compaction of 90 percent as evaluated by ASTM D 1557, except for the upper 12 inches of the backfill beneath vehicular pavements, which should be compacted to a relative compaction of 95 percent as evaluated by ASTM D 1557. Lift thickness for backfill will depend on the type of compaction equipment utilized, but fill should generally be placed in lifts not exceeding 8 inches in loose thickness. Special care should be exercised to avoid damaging the pipe during compaction of the backfill. 12.1.9 Thrust Blocks Thrust restraint for buried pipelines may be achieved by transferring the thrust force to the soil outside the pipe through a thrust block. Thrust blocks may be designed using the magnitude and distribution of passive lateral earth pressures presented on Figure 7. Thrust blocks should be backfilled with granular backfill material and compacted following the recommendations presented in this report. Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 18 12.1.10 Drainage Drainage should be conveyed such that runoff water is conveyed away from slopes and structures to suitable discharge areas by nonerodible devices (e.g., gutters, downspouts, concrete swales, etc.). Positive drainage adjacent to structures should be established and maintained. Positive drainage may be accomplished by providing drainage away from the foundations of the structure at a gradient of 2 percent or steeper for a distance of 5 feet or more outside building perimeters, and further maintained by a graded swale leading to an appropriate outlet, in accordance with the recommendations of the project civil engineer and/or landscape architect. Surface drainage on the site should be provided so that water is not permitted to pond. A gradient of 2 percent or steeper should be maintained and drainage patterns should be established to divert and remove water from the site to appropriate outlets. Care should be taken by the contractor during final grading to preserve any berms, drainage terraces, interceptor swales or other drainage devices of a permanent nature on or adjacent to the property. Drainage patterns established at the time of final grading should be maintained for the life of the project. The property owner and the maintenance personnel should be made aware that altering drainage patterns might be detrimental to foundation performance. 12.2 Seismic Design Parameters Design of the proposed improvements should be performed in accordance with the requirements of the governing jurisdictions and applicable building codes. Table 4 presents the seismic design parameters for the site in accordance with the 2022 CBC guidelines. Table 5 – 2022 California Building Code Seismic Design Criteria Spectral Response Acceleration Parameters Values Site Classification D Seismic Design Category D Mapped MCER Spectral Response Acceleration at Short Periods, Ss 0.95g Mapped MCER Spectral Response Acceleration at 1.0-Second Period, S1 0.348g MCER Spectral Response Acceleration at Short Periods, Adjusted for Site Class, SMS 1.064g MCER Spectral Response Acceleration at 1.0-Second Period, Adjusted for Site Class, SM1 -- Design Spectral Response Acceleration at Short Periods, SDS 0..71g Design Spectral Response Acceleration at 1.0-Second Period, SD1 -- Maximum Considered Earthquake Geometric Mean (MCEG) Peak Ground Acceleration, PGAM 0.491g Docusign Envelope ID: A2CE9085-450A-455B-B280-13C5E9417D88 NINYO & MOORE, A SOCOTEC COMPANY Poinsettia Lane Sewer Replacement Project, Carlsbad, California | 110120001 | October 28, 2025 19 12.3 Underground Structures Underground structures may be designed for lateral pressures represented by the pressure diagrams on Figures 7 and 8. It is recommended that the exterior of underground walls and horizontal and vertical construction joints be waterproofed, as indicated by the project civil engineer. For pipe wall penetrations into the vaults and other structures, standard “water-tight” penetration design should be utilized. To reduce the potential for relative pipe to wall differential settlement, which could cause pipe shearing, we recommend that a pipe joint be located close to the exterior of the wall. The type of joint should be such that minor relative movement can be accommodated. 12.4 Soil Corrosivity Laboratory testing was performed on a representative sample of the onsite earth materials to evaluate pH and electrical resistivity, as well as chloride and sulfate contents. The pH and electrical resistivity tests were performed in accordance with California Test (CT) 643 and the sulfate and chloride content tests were performed in accordance with CT 417 and CT 422, respectively. These laboratory test results are presented in Appendix B. The results of the corrosivity testing indicated electrical resistivities ranging from 340 to 540 ohm-centimeters (ohm-cm), soil pH values of 7.1 to 7.2, chloride contents of 90 to 100 parts per million (ppm), and sulfate contents of 0.050 to 0.104 percent (i.e., 500 to 1,040 ppm). Based on a comparison with the California amended (Caltrans, 2021) corrosion criteria, the onsite soils would be classified as corrosive. Corrosive soils are defined as soil with an electrical resistivity of 1,100 ohm-cm or less, a chloride content of 500 ppm or greater, a sulfate content of 0.15 percent (1,500 ppm) or greater, and/or a pH equal to or less than 5.5. Consideration should be given to retaining a corrosion consultant to further evaluate the laboratory tests and provide appropriate mitigation recommendations, if warranted. 12.5 Concrete Placement 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. As noted, the soil samples tested in this evaluation indicated water-soluble sulfate contents of 0.050 to 0.104 percent (i.e., 500 to 1,040 ppm). Based on the ACI 318 criteria, the site soils would correspond to exposure class S1. For this exposure class, ACI 318 recommends that normal weight concrete in contact with soil possess a compressive strength of 4,000 psi or more and a water-cement ratio of 0.5 or less. Furthermore, we recommend that normal weight concrete in contact with soil use Type II, II/V, or V cement.

The owner or their representative, the agency representatives, the civil engineer, the licensed geotechnical engineer, and the contractor should attend to discuss the plans, the project, and the proposed construction schedule. 12.7 Plan Review and Construction Observation The conclusions and recommendations presented in this report are based on analysis of observed conditions in widely spaced exploratory borings. If conditions are found to vary from those described in this report, Ninyo & Moore should be notified, and additional recommendations will be provided upon request. A licensed geotechnical engineer should review the final project drawings and specifications prior to the commencement of construction. A licensed geotechnical engineer 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 of Ninyo & 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 subcontractors utilizing appropriate techniques and construction materials. 13 LIMITATIONS The field evaluation, laboratory testing, and geotechnical analyses presented in this 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 implied, 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 conditions not observed or described in this report may be encountered during construction. Uncertainties relative to subsurface conditions can be reduced through additional subsurface exploration. Additional subsurface evaluation will be performed upon request. Please also note that our evaluation was limited to assessment of the geotechnical aspects of the project, and did not include evaluation of structural issues, environmental concerns, or the presence of hazardous materials.

The independent evaluations may include, but not be limited to, review of other geotechnical reports prepared for the adjacent areas, site reconnaissance, and additional exploration and laboratory testing. Our conclusions, recommendations, and opinions are based on an analysis of the observed site conditions. It should be understood that the conditions of a site could change with time as a result of natural processes or the activities of man at the subject site or nearby sites. The findings of this report may, therefore, be invalidated over time, in part or in whole, by changes over which Ninyo & Moore has no control. This report is intended exclusively for use by the client. Any use or reuse of the findings, conclusions, and/or recommendations of this report by parties other than the client is undertaken at said parties’ sole risk.

Bulk Samples Bulk samples of representative earth materials were obtained from the exploratory borings. The samples were bagged 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 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.
