Executive Summary The project will install new motorized valves on existing water transmission mains that will allow remote operation of the water system to improve water operations and worker safety. The three motorized valves and related structures and improvements are to be added the El Fuerte Street at Rancho Pancho and the Maerkle Reservoir, as shown in Exhibit 2. The new valves will allow remote operation of the water system at these locations through the Carlsbad Municipal Water District’s (CMWD) Supervisory Control and Data Acquisition system. The construction cost estimate, including contingency funds, is estimated at $1,667,500. The CMWD Board’s approval of the plans, specifications and contract documents are required under Carlsbad Municipal Code Section 3.28.080 – Construction projects, Subsection E because the expected value of this work is greater than $200,000. Staff recommend that the CMWD Board approve the plans, specifications and contract documents, and authorize the Secretary of the Board of Directors to advertise and receive project bids. Nov. 15, 2022 Item #2 Page 1 of 9 Discussion The project will install three motorized valves and related structures and improvements and piping at two locations in the city: 1. El Fuerte Street at Rancho Pancho The scope of work at the El Fuerte site involves installation of a new underground vault and a motorized valve and related piping, electrical, control and improvements on the existing 30-inch steel water transmission main in El Fuerte Street. (Cathodic protection is a method for preventing corrosion on submerged and underground metallic structures through an electrochemical process.) An existing normally closed valve is located at the intersection with Rancho Pancho, which is on the boundary of two water pressure zones and must be operated to ensure adequate water supply and water quality in the distribution system. When staff need to operate the valve, they are exposed to high-speed traffic on El Fuerte Street. The new normally closed valve will be motorized and installed outside of the road to improve operation of the system and worker safety. The project is identified in the 2019 Water Master Plan as Capital Improvement Program Project No. 5050, Normally Closed Valve (Install Motorized Valve). The new motorized valve will be located inside the underground vault, which will be installed away from the road under portions of the existing sidewalk, landscaping and within a 300-square foot easement, (Assessor’s Parcel Number 222-600-01-00). The property owner, Faith Community Church, has agreed to grant the easement necessary for construction, maintenance and operation of the new vault. The proposed cathodic protection improvements along El Fuerte Street will install corrosion test stations at five locations between Rancho Pancho and Alga Road to monitor corrosion of the existing 30-inch steel pipe. These improvements are recommended in the Final Cathodic Protection Plan dated January 2021, which was developed as part of the CMWD’s Asset Management Program and funded by the Cathodic Protection Program, CIP Project No. 5007. 2. Maerkle Reservoir The scope of work at the Maerkle site involves installation of a new underground vault, piping and motorized valves, to replace two existing approximately 30-year-old valves and to automate water system operations. The project was identified by staff as a safety risk due to the need to ascend a 20-foot- high slope to operate the existing 24-inch and 42-inch valves that divert water into the 10-million-gallon tank and the 200-million-gallon reservoir. The new valves will be installed at the base of a slope to facilitate access to the valves and improve worker safety. This component of the work will be funded by the Maerkle Facility Improvements, CIP Project No. 5009. Nov. 15, 2022 Item #2 Page 2 of 9 Staff propose to bundle the work at the two sites into one public works project and accompanying contract because of the similar construction scope for these facilities and to realize economies of scale in the project’s total cost. Phased construction is planned to minimize disruption in water operations. Water shutdowns will be minimized and water services will be kept operational to the extent possible. All construction activities performed at the Maerkle site will be kept on the CMWD property and will involve minimal to no impacts to the community. Construction activities performed at the El Fuerte site will temporarily impact traffic. CMWD staff will work with the Communication & Engagement Department to notify affected residents and businesses prior to and during construction activities. Options Staff provide the following options for the CMWD Board’s consideration: 1. Adopt a resolution approving the plans, specifications and contract documents for the project and authorizing the Secretary of the Board of Directors to advertise for bids for the El Fuerte and Maerkle Motorized Valves Project, CIP Project Nos. 5050, 5009 and 5007 Pros • Improves worker safety and water system operations • Provides a more robust system to ensure water supply and water quality • Bundling the work at the two sites into one project realizes economies of scale in the total project cost Cons • Work will temporarily disrupt traffic during construction 2. Do not adopt a resolution approving the plans, specifications and contract documents and authorizing the Secretary of the Board of Directors to advertise for the El Fuerte and Maerkle Motorized Valves Project, Capital Improvement Program, Project Nos. 5050, 5009 and 5007 Pros • None identified Cons • Worker safety and water distribution reliability would be delayed • Delays to project advertisement for construction bids, selection of contractor and start of construction would occur • Potential increase in construction costs could occur due to inflation and supply chain issues, and delay in awarding construction contract could occur Staff recommend Option 1. Fiscal Analysis The engineer’s construction cost estimate for the project, including contingency funds, is $1,667,500. The estimated total project cost is $2,182,500, which includes construction costs, contingency, staff engineering, staff communications, and construction management and inspection services.

Staff will evaluate the bids received, and the lowest responsive and responsible bidder will be identified. Staff will then return to the CMWD Board to consider the lowest responsive and responsible bid for possible award of a contract to the identified bidder, which is expected to be in winter 2023. Additional budget appropriation, if needed, will be requested at that time. The estimated construction duration is 18 months. Staff anticipate completion of construction in summer 2024. Environmental Evaluation The project will update improvements included as part of the Water Master Plan. The Sewer, Water, and Recycled Water Master Plans, adopted in November 2012, were evaluated in a program environmental impact report prepared and certified by the city (SCH No. 2012021006). The Master Plans were updated in 2019 and an addendum to the program environmental impact report (2019 Addendum) was prepared to address the changes from the 2012 report. Addendum No. 2 to the City of Carlsbad Sewer Master Plan and CMWD Master Plans Update Program Environmental Impact Report was prepared, in accordance with the California Environmental Quality Act – Public Resources Code Section 21000 and the CEQA Guidelines, as amended, California Administrative Code, Title 14, Section 15000. The City Planner has determined the project is within the scope of the adopted program environmental impact report and approved an addendum to document the project changes is appropriate. Addendum No. 2 will be attached to the program environmental impact report, in accordance with CEQA Guidelines Section 15164.

Award and execution of Contract will be as provided for in the Specifications, Instruction to Bidders, or Notice Inviting Bids. 2-2 ASSIGNMENT. No Contract or portion thereof may be assigned without consent of the board, except that the contractor may assign money due or which will accrue to it under the contract. If given written notice, such assignment will be recognized by the Board to the extent permitted by law. Any assignment of money shall be subject to all proper withholdings in favor of the Agency and to all deductions provided for in the Contract. All money withheld, whether assigned or not, shall be subject to being used by the Agency for completion of the work, should the Contractor be in default. 2-3 SUBCONTRACTS. 2-3.1 General. Each Bidder shall comply with the Chapter of the Public Contract Code including Sections 4100 through 4113. The following excerpts or summaries of some of the requirements of this Chapter are included below for information: The Bidder shall set forth in the Bid, as provided in 4104: “(a) The name and location of the place of business of each subcontractor who will perform work or labor or render service to the prime contractor in or about the construction of the work or improvements, or a subcontractor licensed by the State of California who, under subcontract to the prime contractor, specially fabricates and installs a portion of the work or improvement according to detailed drawings contained in the plans and specifications, in an amount in excess of one-half of 1 percent of the prime contractor’s total bid, or, in the case of bids or offers for the construction of streets or highways, including bridges, in excess of one-half of 1 percent of the prime contractor’s total bid or ten thousand dollars ($10,000), whichever is greater.” “(b) The portion of the work which will be done by each such subcontractor under this act. The prime contractor shall list only one subcontractor for each such portion as is defined by the prime contractor in his bid.” If the Contractor fails to specify a Subcontractor or specifies more than one Subcontractor for the same portion of the work to be performed under the Contract (in excess of one-half of 1 percent of the Contractor’s total Bid), the Contractor shall be qualified to perform that portion itself, and shall perform that portion itself, except as otherwise provided in the Code. As provided in Section 4107, no Contractor whose Bid is accepted shall substitute any person as Subcontractor in place of the Subcontractor listed in the original Bid, except for causes and by procedures established in Section 4107.5. This section provides procedures to correct a clerical error in the listing of a Subcontractor. Section 4110 provides that a Contractor violating any of the provisions of the Chapter violates the Contract and the Board may exercise the option either to cancel the Contract or assess the Contractor a penalty in an amount of not more than 10 percent of the subcontract involved, after a public hearing. Revised 6/15/17 Contract No. 5007/5009/5050 Page 59 of 155 Should the Contractor fail to adhere to the provisions requiring the Contractor to complete 50 percent of the contract price with its own organization, the Agency may at its sole discretion elect to cancel the contract or deduct an amount equal to 10 percent of the value of the work performed in excess of 50 percent of the contract price by other than the Contractor’s own organization. The Board shall be the sole body for determination of a violation of these provisions. In any proceedings under this section, the prime contractor shall be entitled to a public hearing before the Board and shall be notified ten (10) days in advance of the time and location of said hearing. The determination of the Board shall be final. 2-3.2 Additional Responsibility. The Contractor shall give personal attention to the fulfillment of the Contract and shall keep the Work under its control. The Contractor shall perform, with its own organization, Contract work amounting to at least 50 percent of the Contract Price except that any designated “Specialty Items” may be performed by subcontract, and the amount of any such “Specialty Items” so performed may be deducted from the Contract Price before computing the amount required to be performed by the Contractor with its own organization. “Specialty Items” will be identified by the Agency in the Bid or Proposal. Where an entire item is subcontracted, the value of work subcontracted will be based on the Contract Unit Price. When a portion of an item is subcontracted, the value of work subcontracted will be based on the estimated percentage of the Contract Unit Price. This will be determined from information submitted by the Contractor, and subject to approval by the Engineer. Before the work of any Subcontractor is started, the Contractor shall submit to the Engineer for approval a written statement showing the work to be subcontracted giving the name and business of each Subcontractor and description and value of each portion of the work to be so subcontracted. 2-3.3 Status of Subcontractors. Subcontractors shall be considered employees of the Contractor, and the Contractor shall be responsible for their work. 2-4 CONTRACT BONDS. Before execution of the Contract, the Bidder shall file surety bonds with the Agency to be approved by the Board in the amounts and for the purposes noted below.

Before final payment will be authorized by the Agency, the Contractor will be required to furnish the Agency with written releases from property owners where side agreements or special easements have been made by the Contractor or where the Contractor's operations, for any reason, have not been kept within the right of way, or from property owners that complained to the Agency or the Agency’s Representative about damage to their property resulting from the Contractor's operations. 2-9 SURVEYING. 2-9.1 General. The Contractor will perform and be responsible for the accuracy of surveying adequate for construction. The Contractor shall set and preserve construction survey stakes and marks for the duration of their usefulness. If any construction survey stakes are lost or disturbed and need to be replaced, such replacement shall be performed at the expense of the Contractor. The Contractor shall notify the Engineer in writing at least 2 Working Days before survey services in connection with the laying out of any portion of the Work. The Contractor shall set all stakes for line and grade. Unless otherwise specified in the Special Provisions, stakes will be set and stationed for alignments for pipelines (sewers, storm drains, potable water, recycled water) and their appurtenances, curbs, headers, structures, rough grade, finish grade and right-of-way or easement boundaries. A corresponding cut or fill to finished grade (or flowline) will be indicated on a grade sheet. 2-9.2 Permanent Survey Markers. The Contractor shall not cover or disturb permanent survey monuments or benchmarks without the consent of the Engineer. Where the Engineer concurs, in writing, with the Contractor that protecting an existing monument in place is impractical, the Contractor shall employ a licensed land surveyor or a registered civil engineer authorized to practice land surveying within the State of California, hereinafter Surveyor, to establish the location of the monument before it is disturbed. The Contractor shall have the monument replaced by the Surveyor no later than thirty (30) days after construction at the site of the replacement is completed. The Surveyor shall file corner record(s) as required by §§ 8772 and 8773, et seq. of the California Business and Professions Code. When a change is made in the finished elevation of the pavement of any roadway in which a permanent survey monument is located, the Contractor shall adjust the monument frame and cover to the new grade within 7 days of paving unless the Engineer shall approve otherwise. Monument frames and covers shall be protected during street sealing or painting projects or be cleaned to the satisfaction of the Engineer. 2-9.3 Line and Grade. All work shall conform to the lines, elevations, and grades shown on the Plans. Three consecutive points set on the same slope shall be used together so that any variation from a straight grade can be detected. Any such variation shall be reported to the Engineer. In the absence of such report, the Contractor shall be responsible for any error in the grade of the Work. Revised 6/15/17 Contract No. 5007/5009/5050 Page 67 of 155 Grades for underground conduits will be set at the surface of the ground. The Contractor shall transfer them to the bottom of the trench. 2-9.4 Payment for Survey, Payment for survey work shall be included in the bid items requiring the survey work and no additional payment will be made. Extension of unit prices for extra work shall include full compensation for attendant survey work and no additional payment will be made.

Revised 6/15/17 Contract No. 5007/5009/5050 Page 69 of 155 SECTION 3 – CHANGES IN WORK 3-1 CHANGES REQUESTED BY THE CONTRACTOR. 3-1.1 General. Changes in the Plans and Specifications, requested in writing by the Contractor, which do not materially affect the Work and which are not detrimental to the Work or to the interests of the Agency, may be granted by the Engineer. Nothing herein shall be construed as granting a right to the Contractor to demand acceptance of such changes. 3-1.2 Payment for Changes Requested by the Contractor. If such changes are granted, they shall be made at a reduction in cost or no additional cost to the Agency. 3-2 CHANGES INITIATED BY THE AGENCY. 3-2.1 General. The Agency may change the Plans, Specifications, character of the work, or quantity of work provided the total arithmetic dollar value of all such changes, both additive and deductive, does not exceed 25 percent of the Contract Price. Should it become necessary to exceed this limitation, the change shall be by written Supplemental Agreement between the Contractor and Agency, unless both parties agree to proceed with the change by Change Order. Change Orders shall be in writing and state the dollar value of the change or established method of payment, any adjustment in contract time of completion, and when negotiated prices are involved, shall provide for the Contractor’s signature indicating acceptance. 3-2.2 Payment. 3-2.2.1 Contract Unit Prices. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does not involve substantial change in character of the work from that shown on the Plans or specified in the Specifications, then an adjustment in payment will be made. This adjustment will be based upon the increase or decrease in quantity and the Contract Unit Price. If the actual quantity of an item of work covered by a Contract Unit Price and constructed in conformance with the Plans and Specifications varies from the Bid quantity by 50 percent or less, payment will be made at the Contract Unit Price. If the actual quantity of said item of work varies from the Bid quantity by more than 50 percent, payment will be made per Section 3-2.2.2 or 3-2.2.3 as appropriate. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does involve a substantial change in the character of the work from that shown on the Plans or specified in the Specifications, an adjustment in payment will be made per Section 3-2.4. 3-2.2.2 Increases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price and constructed in conformance with the Plans and Specifications, exceed the Bid quantity by more than 50 percent, payment for the quantity in excess of 125 percent of the Bid quantity will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3. The Extra Work per Section 3-3, basis of payment, shall not include fixed costs. Fixed costs shall be deemed to have been recovered by the Contractor through payment for 150 percent of the Bid quantity at the Contract Unit Price. Revised 6/15/17 Contract No. 5007/5009/5050 Page 70 of 155 3-2.2.3 Decreases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price, and constructed in conformance with the Plans and Specifications, be less than 50 percent of the Bid quantity, an adjustment in payment will not be made unless so requested in writing by the Contractor. If the Contractor so requests, payment will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3; however, in no case will payment be less than would be made for the actual quantity at the Contract Unit Price nor more than would be made for 50 percent of the Bid quantity at the Contract Unit Price. 3-2.3 Stipulated Unit Prices. Stipulated Unit Prices are unit prices established by the Agency in the Contract Documents as distinguished from Contract Unit Prices submitted by the Contractor. Stipulated Unit Prices may be used for the adjustment of Contract changes when so specified in the Special Provisions. 3-2.4 Agreed Prices. Agreed Prices are prices for new or unforeseen work, or adjustments in Contract Unit Prices per Section 3-2.2, established by mutual agreement between the Contractor and the Agency. If mutual agreement cannot be reached, the Engineer may direct the Contractor to proceed on the basis of Extra Work in accordance per Section 3-3, except as otherwise specified in Sections 3-2.2.2 and 3-2.2.3. 3.2.4.1 Schedule of Values. Prior to construction, Contractor shall provide a schedule of values for all lump sum bid items that shall be used for the purpose of progress payments. The prices shall be valid for the purpose of change orders to the project. 3.2.5 Eliminated Items. Should any Bid item be eliminated in its entirety, payment will be made to the Contractor for its actual costs incurred in connection with the eliminated item prior to notification in writing from the Engineer so stating its elimination. If material conforming to the Plans and Specifications is ordered by the Contractor for use in the eliminated item prior to the date of notification of elimination by the Engineer, and if the order for that material 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. Revised 6/15/17 Contract No. 5007/5009/5050 Page 71 of 155 3-3.2.2 Basis for Establishing Costs. (a) Labor. The costs of labor will be the actual cost for wages of workers performing the extra work at the time the extra work is done, plus employer payments of payroll taxes, workers 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. Revised 6/15/17 Contract No. 5007/5009/5050 Page 72 of 155 The reported rental time for equipment already at the Work site shall be the duration of its use on the extra work. This time begins when equipment is first put into actual operation on the extra work, plus the time required to move it from its previous site and back, or to a closer site. (d) Other Items. The Agency may authorize other items which may be required on the extra work, including labor, services, material, and equipment. These items must be different in their nature from those required for the Work and be of a type not ordinarily available from the 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.

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. Revised 6/15/17 Contract No. 5007/5009/5050 Page 83 of 155 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 Revised 6/15/17 Contract No. 5007/5009/5050 Page 84 of 155 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. Revised 6/15/17 Contract No. 5007/5009/5050 Page 85 of 155 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 the location and depth (potholing) of every crossing point between the proposed pipeline and the existing utilities shown on the plan or that have been marked by the respective owners per Section 402-1. The pothole log shall be submitted a minimum of one week prior to excavating the crossing location. 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, type, and horizontal and vertical locations (bearing and slope) and submit the data to the Engineer in accordance with Section 2-5.3. If no separate pay 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. Revised 6/15/17 Contract No. 5007/5009/5050 Page 86 of 155 The Contractor shall immediately notify the Engineer and the utility owner if any utility is disturbed or damaged. The Contractor shall bear the costs of repair or replacement of any utility damaged if located as noted in Section 5-1. When placing concrete around or contiguous to any non-metallic utility installation, the Contractor shall at its expense: 1. Furnish and install a 2-inch cushion of expansion joint material or other similar resilient material; or 2. Provide a sleeve or other opening which will result in a 2-inch minimum-clear annular space between the concrete and the utility; or 3. Provide other acceptable means to prevent embedment in or bonding to the concrete. Where concrete is used for backfill or for structures which would result in embedment, or partial embedment, of a metallic utility installation; or where the coating, bedding or other cathodic 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 Revised 6/15/17 Contract No. 5007/5009/5050 Page 87 of 155 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. 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. Revised 6/15/17 Contract No. 5007/5009/5050 Page 88 of 155 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. Close cooperation with CMWD Operations staff will be required prior to water utility shutdowns, construction, testing, and project completion. Revised 6/15/17 Contract No. 5007/5009/5050 Page 89 of 155 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, Revised 6/15/17 Contract No. 5007/5009/5050 Page 90 of 155 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 thirty (30) 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 30 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. Revised 6/15/17 Contract No. 5007/5009/5050 Page 91 of 155 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 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. All costs of prosecuting the Work as described herein shall be included in the Contractor’s Bid. Should the Contractor fail to take the necessary steps to fully accomplish said purposes, after orders of the Engineer, the Engineer may suspend the work in whole or part, until the Contractor takes said steps. Revised 6/15/17 Contract No. 5007/5009/5050 Page 92 of 155 As soon as possible under the provisions of the Specifications, the Contractor shall backfill all excavations and restore to usefulness all improvements existing prior to the start of the Work. If Work is suspended through no fault of the Agency, all expenses and losses incurred by the Contractor during such suspensions shall be borne by the Contractor. If the Contractor fails to properly provide for public safety, traffic, and protection of the Work during periods of suspension, the Agency may elect to do so, and deduct the cost thereof from monies due the Contractor. Such actions will not relieve the Contractor from liability. 6-2.1 Order of Work. The work to be done shall consist of furnishing all labor, equipment and materials, and performing all operations necessary to complete the Work as shown or specified on the Contract Documents. The work descriptions in this section are an overview only and shall not relieve the Contractor from its responsibilities to conduct all coordination and perform the Work in accordance with the Contract Documents.

Carlsbad Municipal Water District Electrical Identification El Fuerte & Maerkle Motorized Valves 13549 16195 - 2 C. Wire Labeling Standard: The intent of this standard is to provide for a wire marking system that clearly identifies the termination point at either end of any given conductor. Implementing this system would facilitate quicker troubleshooting due to the immediate recognition of a wires origination and destination without the need of contract drawings. 1. Method: The most powerful controller would take precedence as the first termination point called out on the label. The second half of the label would be the termination point at the other end. The wire label would remain the same at both ends of the wire. For example: a. If a wire ran from the RTU, Terminal Block number 4, Point 25 to the Motor Control Center, Pump 1 bucket, Field Terminal Block, Point 3, the tag would read; RTU-TB4-25/MCC-P1-FTB-3. b. A wire that runs from the Motor Control Center, Pump 1 bucket, Field Terminal Block, Point 22 to the common of High-Pressure Switch PSH-101, would read; MCC-P1-FTB-22/PSH-101-C. c. An analog signal conductor from the positive connection of Pressure Transmitter PIT-111 to the RTU, Terminal Block number 6, Point 6, would read; RTU-TB6- 6/PIT-111-+. d. A circuit conductor originating from panel “LP” circuit breaker number 5 and feeding exhaust fan EF1 would read, LP-5/EF1. e. Any conductor going to a relay would include the actual relay base pin number. For example, a conductor from the RTU Terminal Block 2 point 12 to relay CR1 pin 7 would read, RTU-TB2-12/CR1-7. f. Motor feeders are not required to be marked with anything other than phase colors. 2.03 CONDUIT TAGS A.

The Carlsbad Municipal Water District (CMWD) is installing new motorized valves at two sites within the City of Carlsbad. The El Fuerte site (El Fuerte), is in the public right-of-way, north of the intersection of El Fuerte Street and Rancho Pancho. The scope of work at this site includes installation of a new valve vault along the existing 30-inch diameter cement-mortar lined and coated (CML&C) steel pipeline. The Maerkle site (Maerkle), is located approximately 2.5-miles north of El Fuerte, near the 10-million-gallon Maerkle Reservoir. The scope of work at this site includes relocating two manually operated valves to a more conveniently accessed location (CMWD, 2021). A list of references is provided in Section 11.0 of this report. 1.1 Purposes and Scope of Services This report was prepared in general accordance with the referenced proposal (Group Delta, 2021). The purpose of this investigation is to characterize the subsurface conditions within the areas of proposed improvement and to provide geotechnical recommendations for pipeline and vault designs and earthwork construction. While this report provides an interpretation of the geologic conditions, it should not be considered a contractual statement of geotechnical conditions (i.e., a baseline report). We provided the following scope of services: • A review of readily available background references, including previously prepared geotechnical reports, geologic, fault, topographic and hazard maps, and groundwater data for the El Fuerte and Maerkle sites; • A reconnaissance of El Fuerte and delineation of the boring locations for underground utility mark out by Underground Service Alert (USA); • Obtaining a City of Carlsbad Right-of-Way Permit (ROW2021-0849) to perform our subsurface exploration at El Fuerte; • A subsurface exploration consisting of 1 boring at El Fuerte; • Laboratory testing of selected soil samples collected from the El Fuerte boring; • Interpretation and analysis of the field and laboratory data to develop geotechnical parameters and recommendations; and • Preparation of this report summarizing our findings, conclusions, and recommendations. Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 2 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx 1.2 Site Description Both sites are located within the City of Carlsbad, California. A detailed description of each site follows. The general vicinity of the sites is shown on the Site Location Map, Figure 1A. 1.2.1 Maerkle Site The Maerkle site is located at the northern end of Sunny Creek Road within the vicinity of the 10- million-gallon (MG) buried Maerkle Tank and the 200 MG Maerkle Reservoir (Ninyo & Moore, 2011). This site contains a hydroelectric facility and a pressure reducing station adjacent to the asphalt paved access road. The site is sparsely vegetated with desert brush and native vegetation. To the east of the access road, the 10 MG reservoir is buried and surrounded with a fill slope which is approximately 20 feet tall. The elevation of this site is approximately 490 feet above mean sea level (MSL) along the access road at the bottom of the fill slope. An overhead view of this site can be found in Figure 1B, Maerkle Site Aerial. 1.2.2 El Fuerte Site The El Fuerte site is located within El Fuerte Street near the intersection of Rancho Pancho and the Faith Community Church. An existing 30-inch water line currently runs beneath the center of the two northwest bound lanes. El Fuerte Street is Hot-Mix Asphalt (HMA) paved and contains sidewalks with curbs and gutters along the alignment. The road and alignment slope downward slightly to the northwest, with elevations ranging from 190 to 200 feet above MSL. An overhead view of this site can be found in Figure 1C, E Fuerte Site Aerial. 1.3 Proposed Improvements This project proposes to install three new motorized valves within new vaults at the sites (CMWD, 2021). A detailed description of each site’s proposed improvements is provided below. 1.3.1 Maerkle Site Currently, the manually operated valves for the active 24-inch and 42- inch diameter steel piping are buried and located near the top of the 20-foot fill slope. These valves are difficult to access and will therefore be relocated to a new vault at the toe of the slope. The new vault will require construction of additional pipeline and appurtenances, as well as the installation of motorized valves within the new vault to facilitate remote operation. The location of the proposed new vault can be seen on the site aerial in Figure 1B. 1.3.2 El Fuerte Site A new motor operated, normally closed valve is planned to be installed north of the intersection of El Fuerte and Rancho Pancho to reduce the distance between currently existing valves, and therefore, reduce the volume of water flushed through the lines seasonally. Two potential vault Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 3 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx locations to house the valve are being considered at this site. The first option is to install the vault directly in line with the existing 30-inch diameter steel transmission main within the right-of-way. The second option is to install the vault in the vegetated planter area just north of the intersection of Rancho Pancho and El Fuerte Street. Both potential vault locations can be seen on the site aerial in Figure 1C. 2.0 DESKTOP, FIELD, AND LABORATORY INVESTIGATION Group Delta performed a field and laboratory investigation of the subsurface conditions at El Fuerte, and a desktop study for Maerkle. 2.1 Maerkle Desktop Study The desktop study for Maerkle utilized background references, including reports provided by Dudek, geologic, fault, topographic and hazard maps, and environmental and groundwater data. No subsurface exploration or laboratory testing was performed for this site. A list of references used for this study is included in Section 11.0 of this report. 2.2 El Fuerte Field Investigation The field investigation included a site reconnaissance, performed on September 22, a field meeting with a City of Carlsbad inspector on October 20, and drilling one boring on October 27, 2021. Boring A-21-001 was drilled to a target depth of 20.0 feet below ground surface (bgs) using a Fraste PL-G limited access drill rig with a 6-inch diameter hollow stem auger. The boring was located by use of hand-held GPS, aerial photographs, and field tape measurement from available landmarks. The approximate location of the boring is shown on the Exploration Location Plan, Figure 2. A detailed description of the field exploration is presented in Appendix A. Within this appendix, the boring record, including the approximate latitude, longitude, and elevation are presented in Figure A-2. The exploration was conducted in general conformance with the 2010 Caltrans “Soil and Rock Logging, Classification, and Presentation Manual”. 2.3 El Fuerte Laboratory Investigation Laboratory testing of selected samples from boring A-21-001 was performed in accordance with applicable Caltrans and ASTM standards. The following laboratory tests were conducted to determine the physical and engineering properties of the soil samples: • Moisture content; • Grain size distribution and percent passing No. 200 sieve; • Direct shear; • Laboratory compaction test; • Expansion Index; and Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 4 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx • Soil Corrosivity. Moisture content, soil gradation and percent passing No. 200 sieve, and expansion index laboratory test results are presented on the boring logs in the Appendix A. Detailed descriptions of the tests performed and their results are presented in Appendix B. 3.0 GEOLOGY AND SUBSURFACE CONDITIONS As shown in Figure 3, the site is located within the coastal plain section of the Peninsular Ranges geomorphic province of Southern California. The coastal plain generally consists of subdued landforms underlain by marine sedimentary formations. 3.1 Maerkle Site The geologic conditions at the Maerkle site were interpreted based on numerous previously completed subsurface investigations (Ninyo & Moore, 2011; M&T AGRA, 1993; AGRA E&E, 1993). The various geologic materials expected at the site are described in detail below. 3.1.1 Undocumented Fill The 10MG Maerkle Tank is buried and surrounded by an approximately 20-foot-tall fill slope. Though this material was potentially documented and tested during installation of the original reservoir, an as-graded report was not available for our review. For this reason, we are classifying it as undocumented fill. No information regarding these fill soils were available in the background information we reviewed; however, the material may have originated from onsite colluvium. Organics and vegetation are expected to be present in the surficial materials. 3.1.2 Colluvium Colluvium is reported to be present in the upper 6 to 12-inches at Maerkle within the area of the new vault. Colluvium is an accumulation of soil and weathered formational materials that forms on slopes as a result of slow downhill creep due to gravity. The colluvial soils are expected to consist of silty sand (SM) to clayey sand (SC) with trace amounts of fine to coarse gravel. Organics and vegetation are expected to be present in this material (Ninyo & Moore, 2011). 3.1.3 Tonalite (Map Symbol - Kt) According to published geologic maps, the Maerkle site is underlain by unnamed mid-Cretaceous aged Tonalite (CGS, 2007). This plutonic igneous rock is likely to be encountered within the upper foot of the existing ground surface in the area of the new vault, as indicated by nearby borings (Ninyo & Moore, 2011). This material is described by Ninyo & Moore as “light reddish brown to reddish brown, damp, weathered granitic rock” (2011). Samples of the tonalite were observed to break down upon excavation into reddish brown silty sand (SM) with varying amounts of gravel and rock-sized fragments (Ninyo & Moore, 2011). Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 5 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx Geophysical survey data conducted for the nearby 200 MG Maerkle Dam Reservoir indicates a potential for moderate excavation difficulty in the upper 15 feet, and extremely difficult excavatability deeper than 15 feet within the weathered rock (M&T AGRA, 1993). 3.2 El Fuerte Site The geologic materials encountered and mapped at the sites are described in detail below. 3.2.1 Documented Fill Fill soils were encountered to the total depth explored in the boring completed at the El Fuerte site. According to the referenced report prepared by Geocon (1993), this fill was placed for the El Fuerte road embankment project. The fill is referred to as documented by Geocon, and previously stated to have been tested and observed during placement by Woodward-Clyde Consultants, however, their report was not available for our review. Based on historical aerial photos and topographic maps of the El Fuerte area, up to 25 feet of fill may have been placed in this area previously. At least 20 feet of fill was observed in our boring. The fill soils were primarily observed to consist of stiff sandy lean clay (Unified Soil Classification System - CL) and medium dense clayey sand (SC) with trace amounts of fine gravel. Expansion indices (EI) within the fill soils indicate a medium expansion potential, with a reported EI of 66. Organics and vegetation are expected to be present in the surficial materials. 3.2.2 Santiago Formation (Tsa) Published local geologic maps indicate El Fuerte is underlain by Santiago Formation (CGS, 2007). These Eocene age sedimentary materials primarily consist of gray to brownish-gray coarse- grained sandstone. Greenish-brown claystone also exists laterally throughout this formation. The Santiago Formation was not encountered in our explorations and is unlikely to be encountered during trenching activities. 3.3 Groundwater No seepage or groundwater was observed in the boring conducted at El Fuerte for this investigation. Similarly, no groundwater was observed during the previously completed investigation at Maerkle (Ninyo & Moore, 2011). It should be noted that changes in rainfall, irrigation practices or alteration of surface drainage may produce seepage or locally perched groundwater conditions. Such conditions are difficult to predict and are typically mitigated if and where they occur. Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 6 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx 4.0 GEOLOGIC HAZARDS The main geologic hazard should be the potential for strong ground shaking from a nearby or distant earthquake. Each of the potential geologic hazards is described in more detail below. 4.1 Ground Rupture Ground rupture is the result of movement on an active fault reaching the ground surface. No indications of Holocene-active or potentially active faulting were found in our reconnaissance or literature review. The sites are not located within a State of California Earthquake Fault Zone. The nearest known Holocene-active fault is the Newport-Inglewood fault located about 7.5 and 9-miles (12 and 14.5-kilometers) south-west of El Fuerte and Maerkle, respectively (USGS, 2014). Ground rupture is not considered to be a significant geologic hazard at these sites. The locations of known active faults within about a 30-mile (500-kilometer) radius of the sites are shown on Figure 4, Fault Location Map. 4.2 Strong Ground Shaking The main geologic hazard at these sites is the potential for strong ground shaking from a nearby or distant earthquake, although the types of permanent works for this project that are embedded in the ground are typically not designed for strong ground shaking. 4.3 Soil Liquefaction and Seismic Compaction Liquefaction is a phenomenon where loose, saturated, coarse-grained soils (with less than 50% passing the No. 200 sieve) lose their strength and acquire some mobility from strong ground shaking induced by earthquakes. The secondary effects of liquefaction include sand boils, settlement, reduced soil shear strength, lateral spreading, and global instability (flow slides) in areas with sloping ground. Seismic compaction is the settlement of loose unsaturated granular soils from strong ground shaking. Groundwater was not encountered in our exploration at El Fuerte, and the site is primarily underlain by relatively dense, well graded fill soils and very dense Eocene formation at depth. Maerkle is underlain by Tonalite, and groundwater was not encountered during previous geotechnical investigations (Ninyo & Moore, 2011). Therefore, the potential for soil liquefaction and its secondary effects should be very low at both sites. 4.4 Landslides and Slope Instability Evidence of ancient landslides or slope instabilities was not observed during our literature review or site reconnaissance within the areas of the future improvements at either site. Landslides have been mapped east of El Fuerte; however, the area has been graded to be relatively flat since mapping was completed, and landslides are unlikely at this time. Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 7 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx 5.0 CONCLUSIONS Based on the results of this investigation, we provide the following conclusions regarding the geotechnical aspects of design and construction for each site: 5.1 Maerkle Site • Maerkle is primarily underlain by Cretaceous aged Tonalite. This material is described by Ninyo & Moore as “light reddish brown to reddish brown, damp, weathered granitic rock” (2011). • Geophysical survey data conducted nearby indicates a potential for moderate excavation difficulty in the upper 15 feet, and extremely difficult excavatability deeper than 15 feet within the weathered rock (M&T AGRA, 1993). Accordingly, difficult excavation and the use of rock breakers or heavy ripping equipment should be anticipated. • Seepage or groundwater was not observed in the borings previously conducted at Maerkle and shallow groundwater is not expected to be encountered during construction. However, changes in rainfall, irrigation practices or alterations to surface drainage could produce local zones of seepage or perched groundwater. • Excavated granitic rock materials should be suitable for reuse as fill, provided the material are processed to a suitable size as discussed in the Earthwork Recommendations section of this report. Excavated undocumented fill materials should be tested to determine whether they are appropriate for use as backfill. • The main geologic hazard is the potential for strong ground shaking from a nearby or distant earthquake, although the types of permanent works for this project that are embedded in the ground are typically not designed for strong ground shaking. 5.2 El Fuerte Site • El Fuerte is primarily underlain by fill as observed in the boring conducted for this investigation. The fill soils primarily consist of sandy lean clay (CL) and clayey sand (SC) with trace amounts of fine gravel. Expansion index testing of the fill soils indicates a medium expansion potential. • The onsite soils at El Fuerte should be excavatable with conventional construction equipment in good working order. • Seepage or groundwater was not observed in the boring conducted by us at El Fuerte and shallow groundwater is not expected to be encountered during construction. However, changes in rainfall, irrigation practices or alterations to surface drainage could produce local zones of seepage or perched groundwater. Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 8 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx • Excavated soils are not suitable for use as backfill due to the in-situ materials expansion potential, with a reported EI of 66. • The main geologic hazard is the potential for strong ground shaking from a nearby or distant earthquake, although the types of permanent works for this project that are embedded in the ground are typically not designed for strong ground shaking. 6.0 RECOMMENDATIONS The following sections provide geotechnical recommendations for the design of permanent improvements (pipelines and supporting appurtenances, utility vaults, and trench pavement resurfacing), earthwork and temporary slopes and excavations. The recommendations are based on empirical and analytical methods typical of the standards of practice in southern California. If these recommendations do not cover a specific feature of the project, please contact our office for revisions or amendments. 6.1 Earthwork Earthwork is anticipated to include temporary trench and backfilling of these excavations with properly compacted fill. Substantial cut and fill earthwork are not expected. Earthwork should be completed in accordance with relevant City of Carlsbad ordinances and the Standard Specifications for Public Works Construction (Greenbook). The following recommendations are provided for aspects of the earthwork that are specific to this project. These recommendations are subject to revision based on the conditions observed by the project Geotechnical Engineer during earthwork. 6.1.1 Site Preparation Plants, roots, and tree stumps should be removed to the extent that organic material is not generally present. Clearing and grubbing should extend a minimum of one foot outside the proposed excavation areas. Abandoned underground utilities and other buried structures should be excavated and the trenches properly backfilled. All vegetation debris and rubble from demolition should be removed and legally disposed of offsite. Subgrade disturbed by demolition and excavation should be restored with properly placed and compacted fill. The fill should not be placed until the bottom of the excavation is approved by the Geotechnical Engineer or their field designate. Loose or soft zones in the subgrade should be replaced with properly compacted backfill as required by the Geotechnical Engineer or their field designate. Depending on the size of the area to receive new fill, localized probing or proof rolling may be needed to identify soft or loose areas requiring removal and re-compaction. Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 9 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx 6.1.2 Reuse of Existing Soils 6.1.2.1 Maerkle Site Existing colluvium and soils derived from formational Tonalite should be suitable for reuse as trench backfill, less any rock or cemented fragments larger that 3-inches in diameter, potentially expansive soils, or saturated soils. These materials, if encountered, should be replaced with import fill materials that are suitable for use as fill and evaluated by the Geotechnical Engineer. Core stones and zones of hard rock may be encountered during trench and vault excavation. 6.1.2.2 El Fuerte Site Existing soils derived from site are not appropriate for use as trench or vault backfill due to its medium expansion potential, with a reported EI of 66. Soil with an EI greater than 20 should be removed and disposed offsite. 6.1.3 Import Materials A Geotechnical Engineer should review and test proposed import materials before their use. Imported soil should have no rocks larger than 3-inches in maximum dimension, have less than 35 percent fines passing the No. 200 sieve, be non-corrosive, and an Expansion Index less than 20 (ASTM D4829). These soils should not have any perishable, spongy, deleterious, or otherwise unsuitable material. In general, import materials should consist of non-plastic sandy soils. 6.1.4 Sand and Cement Slurry A two-sack sand and cement slurry may also be used for structural fill as an alternative to compacted soil. Slurry is often useful in confined areas which may be difficult to access with typical compaction equipment. Samples of the slurry should be fabricated and tested for compressive strength during construction. A 28-day compressive strength of 100 pounds per square inch (psi) or more is recommended for the two-sack sand and cement slurry. In accordance with Carlsbad Standard Detail GS-24, maximum 8-inch slump 190-E-400 slurry backfill is required above the pipe zone to surface for narrow trenches (less than 6 inches wide). 6.1.5 Fill Compaction All fill and backfill should be placed in loose lifts that do not exceed 8-inches in thickness at a moisture content that is above the optimum moisture content for compaction using equipment capable of producing a uniform compaction. In accordance with the Carlsbad typical trench section (W-2), the minimum recommended relative compaction is 90 percent of the maximum dry density in unpaved areas and 95% in paved areas, based on the latest version of ASTM D1557. Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 10 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx 6.1.6 Subgrade Stabilization All excavation bottoms should be firm and unyielding prior to placing fill or improvements. In areas of saturated or “pumping” subgrade, a geogrid such as Tensar BX-1200 or Terragrid RX1200 may be placed directly on the excavation bottom, and then covered with at least 12 inches of crushed miscellaneous base. Once the excavation is firm enough to attain the required compaction within the base, the remainder of the excavation may be backfilled using either compacted soil or aggregate base. 6.2 Underground Utilities and Vaults The following sections provide geotechnical recommendations for design parameters that are commonly used in the design of underground utilities and vaults. 6.2.1 Soil Vertical Loads A soil unit weight of 130 pounds per cubic (pcf) may be used to evaluate soil loads for pipelines. The permissible depth of cover should be checked where new fill will be placed over underground utilities that will remain. 6.2.2 Lateral Earth Pressures Permanent subterranean vaults that are restrained from lateral movement may be designed using an equivalent fluid pressure of 60 pcf. A generic lateral traffic surcharge of 125 pounds per square foot (psf) should be applied as a rectangular loading distribution along the entire height of the vault when located within the traveled way for preliminary design purposes. Evaluation of surcharge loads associated with specific vehicles, construction equipment and other loading that will load the walls should be considered when selecting the design surcharge value. 6.2.3 Allowable Vertical Bearing Pressures The vault foundations should be designed by the project structural engineer. For the El Fuerte site, an allowable vertical bearing pressure of 2,000 psf may be used for design. An allowable vertical bearing pressure of 3,000 psf may be used for design at the Maerkle site. The estimated total settlement of properly designed and constructed foundations founded on materials prepared in accordance with the Site Preparation section of this report should be less than 1 inch. The differential settlement should be less than ½-inch over the planned length of the structure. 6.2.4 Thrust Blocks Lateral resistance for thrust blocks may be evaluated by a passive pressure value of 250 psf per foot of embedment, assuming a triangular distribution. Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 11 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx 6.2.5 Modulus of Soil Reaction The modulus of soil reaction (E’) is used to characterize the stiffness of soil backfill placed along the sides of buried flexible pipelines. To evaluate deflection due to the load associated with trench backfill over the pipe, we recommend using 1,000 pounds per square inch (psi) assuming granular bedding material is placed around the pipe. 6.2.6 Vault Foundations Vault foundations should be designed using a coefficient of vertical subgrade reaction (k1) of 75 pounds per cubic-inch (pci) for the El Fuerte site, and 200 pci for the Maerkle site. Note that k1 should be adjusted for square foundation sizes wider than one foot using the following equation: kB = k1 [(B +1) / 2B]2 where: kB = the modulus of subgrade reaction for a foundation of width ‘B’ B = foundation width in feet The Geotechnical Engineer should review the value used for design, including how it is applied in structural engineering software. 6.2.7 Pipe Bedding Material Typical pipe bedding as specified in the Standard Specifications for Public Works Construction or City of Carlsbad Standard Drawings may be used. For water pipeline trenches wider than six inches, the pipe zone must be backfilled with clean, imported sand, in accordance with the Typical Trench Section standard drawing (W-2). The pipeline must be supported on a minimum of 6 inches of bedding material, with at least 12 inches of shading over the pipe. These materials should be mechanically compacted to 90%. For electrical trenches narrower than 6 inches, the pipe zone must be backfilled with mortar sand in accordance with the Narrow Trench Backfill & Asphalt Concrete Resurfacing standard detail (GS-24). The conduit and cable must be covered with a minimum of 6 inches of shading, mechanically compacted to 95% relative compaction. 6.2.8 Existing Utilities The permissible depth of cover and settlement tolerances should be evaluated where new fill will be placed over underground utilities that will remain. The permissible depth of cover and settlement tolerances for construction traffic and equipment loads should also be evaluated. Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 12 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx 6.3 Trench Pavement Resurfacing Trench pavement resurfacing should be completed as shown in the City of Carlsbad Standard Drawings GS-24 through GS-28, as applicable. We recommend an asphalt concrete thickness equal to existing plus 1-inch and a minimum 4-inch thickness. If encountered, we recommend the aggregate base thickness match existing minus 1-inch to accommodate the additional 1-inch of asphalt concrete with a minimum 4 inches of aggregate base. 6.4 Corrosion The corrosion potential of on-site soils should be further assessed during a design-level investigation. A Corrosion Consultant may be contacted for specific recommendations. 6.4.1 Maerkle Site Ninyo & Moore analyzed a representative sample of the surficial soils in 2011 to evaluate corrosion characteristics. Based on the laboratory test results, the in-situ soils are classified as moderately corrosive to buried metals, and borderline severely corrosive to cement. A type V cement should be used for buried cement structures. 6.4.2 El Fuerte Site A representative sample collected near the surface of the site soils was tested to evaluate corrosion characteristics. Based on the laboratory test results, the in-situ soils are classified as very corrosive to buried metals, and severely corrosive to cement. A type V cement should be used for buried cement structures. Results of the corrosion test can be found in Appendix B. 7.0 CONSTRUCTION CONSIDERATIONS 7.1 Temporary Excavations The following sections provide recommendations for preliminary design of temporary slopes and shoring. The final design and the geotechnical parameters used for this design should ultimately be developed and selected by the Contractor’s Shoring Engineer and Geotechnical Engineer. Existing infrastructure that is within a 2:1 H:V line projected up from the bottom edge (toe) of temporary slopes and shoring should be monitored during construction. 7.1.1 Temporary Slopes The design and construction of temporary slopes, as well as their maintenance and monitoring during construction, is the responsibility of the Contractor. The Contractor should have a geotechnical or geological professional evaluate the soil/rock conditions encountered during excavation to determine permissible temporary slope inclinations and other measures as required by California OSHA (Cal/OSHA). Based on the existing data interpreted from site Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 13 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx reconnaissance, desktop study, and subsurface exploration the following Cal/OSHA Soil Types may be assumed for planning purposes. Geological Unit Cal/OSHA Soil Type Fill/Colluvium Type C Weathered Tonalite Type B The Contractor should note the materials encountered in construction excavations could vary significantly across the site. The above assessment of Cal/OSHA Soil Type for temporary slopes is based on preliminary engineering classifications of material encountered in widely spaced explorations. The Contractor's geotechnical or geological professional should observe and map mass excavations and temporary slopes at regular intervals during excavation and assess the stability of temporary slopes, as necessary. Note that slopes that exceed 20 feet in height require specific analyses by a registered Civil Engineer. 7.1.2 Shoring Shoring should be designed to resist the pressure exerted by the retained soils plus any additional lateral forces resulting from loads placed near the top of the excavation. Shoring for the project is expected to consist of trench boxes or shields, and cantilever to braced excavations. The design of trench boxes or shields with a level backfill surface may use the Cal/OSHA Soil Types, subject to limitations provided above and the proprietary aspects of the box or shield system adopted. Cantilever and braced shoring with a level backfill surface may be designed using the lateral earth pressures provided in Figures 5A and 5B, respectively. Surcharges within a 1:1 plane extending back and up from the bottom of the excavation should be accounted for in the shoring design. One-third of the maximum surcharge load should be used to develop a rectangular pressure distribution. Lateral loads for line or point loads behind the wall can be provided on an as needed basis. The design of soldier piles that are fully embedded below the bottom of the excavation in competent formational materials may use an allowable passive pressure of 350 pcf, as shown in Figures 5A and 5B. For embedment into fill materials, an allowable passive pressure of 250 pcf should be utilized. To account for three dimensional effects, the area generating the passive resistance can be assumed to have an effective width of twice the concreted pile diameter. Shoring systems should be stable against geotechnical failure mechanisms, such as external stability, foundation heave and hydraulic failure. The shoring designer is responsible for evaluating structural failure mechanisms, such as the lateral and axial capacity of the soldier pile (bending or penetration failure) and yielding of the lagging. Note the following construction considerations for cantilever soldier pile shoring: Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 14 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx 1. The concrete placed within the upper portion of the soldier piles (down to the bottom of the proposed excavation) may be a lean sand-cement mix (2-sacks cement per cubic yard concrete) to facilitate placement of the lagging. However, structural concrete should be used for the portions of the soldier piles embedded below the bottom of the planned excavations. 2. The construction sequence should be considered by the shoring designer, and the various phases of the wall construction should be evaluated for internal stability of the shoring system. 3. If soldier piles are used, the contractor should implement a program to monitor potential horizontal or vertical movement of the ground surrounding the excavation. The program usually incorporates deformation monitoring points installed on the shoring and on the ground and structures behind the shoring. A baseline dataset is established before excavation or fill placement begins with weekly, or more frequent readings during the stages of construction that have the potential to cause movement. 7.2 Excavation Characteristics 7.2.1 Maerkle Site Based on data found in previously conducted field investigations, the site is primarily underlain with granitic material beneath a thin layer of fill. These materials should be excavatable with standard heavy-duty equipment, however, the use of rock breakers or heavy-duty ripping equipment should be anticipated (Ninyo & Moore, 2011). An excerpt from M&T AGRA (1993), regarding excavatability is included below, along with a table summarizing the shear wave velocities described in their report: “As a general statement, heavy weight hydraulic excavators (such as the Caterpillar Model 245) experience difficulty when digging homogenous rock-like materials having seismic propagation velocities (P-wave) greater than 4000 feet per second (ft/s). The upper limit of excavatability can be taken to about 5000 ft/s. Large, single shank ripper-equipped bulldozers can successfully excavate materials in the 6,000 to 8,000 ft/s range, depending on rock structure.” Depth (bgs) Shear Wave Velocity (ft/s) Upper 15 ft 2,200 - 4,800 15 to 20 ft 7,000 to 11,000 7.2.2 El Fuerte Site The results from our field exploration indicate the trench and vault excavations will be primarily in clayey fill. The onsite soils are considered excavatable with conventional construction equipment in good working order, however, oversized materials could be encountered during Geotechnical Investigation Group Delta Project No. SD700 El Fuerte and Maerkle Motorized Valves Project January 12, 2022 Dudek Page 15 Dudek El Fuerte and Maerkle Valves - Geotechnical Investigation (Group Delta 21-0146).docx excavation operations. Note that the geotechnical boring was drilled below the bottom of vault elevation, using a 6-inch diameter hollow stem auger on a limited access drill rig. 8.0 ADDITIONAL GEOTECHNICAL SERVICES Development of the project may require the additional geotechnical services listed below: • Updating recommendations for design changes; • Reviewing the project drawings for compatibility with the recommendations provided in the geotechnical report; • Assisting with the development of construction documentation (e.g. specifications and special provisions); • Responding to comments by the reviewing agencies; and • Finalizing the geotechnical report as needed for permits. 9.0 CONSTRUCTION OBSERVATION AND TESTING The restoration of subgrade disturbed by demolition, the preparation of subgrade for pavement and the placement of trench backfill and engineered fill should be completed under the observation and testing services of a geotechnical professional supervised by a Geotechnical Engineer. Tests should be taken to determine the in-place moisture and relative compaction of the fill. A compaction report should be prepared following the completion of the geotechnically significant forms of construction. The report should document the observations, laboratory testing, and field testing performed under the supervision of the project Geotechnical Engineer. 10.0 LIMITATIONS This report was prepared using the degree of care and skill ordinarily exercised, under similar circumstances, by reputable geotechnical consultants practicing in similar localities.

The location of the exploration is presented in Figure 2 of the main report. A summary of field explorations is presented in Table A-1. Prior to beginning the exploration program, access permission and drilling permits were obtained as necessary from the City of Carlsbad. Subsurface utility maps were reviewed prior to selecting locations for subsurface investigations. Three potential locations were chosen for this exploration in case of utility conflicts. Underground Service Alert (USA) was notified, and each potential exploration location was cleared for underground utilities by a private utility locating company. Approved traffic control plans were implemented during field activities. The exploration methods are described in the following sections. A.2 Soil Drilling and Sampling Drilling, Logging, and Soil Classification Borings were performed by Group Delta’s drilling subcontractors Pacific Drilling under the continuous technical supervision of a Group Delta field engineer, who visually inspected the soil samples, maintained detailed records of the borings, and visually / manually classified the soils in accordance with the ASTM D 2488 and the Unified Soil Classification System (USCS). Logging and classification were performed in general accordance with Caltrans “Soil and Rock Logging, Classification, and Presentation Manual (2010 Edition)”. A Boring Record Legend and Key for Soil Classification are presented in Figures A-1A through A-1E. The boring record is presented in Figure A-2A. Sampling Bulk samples of soil cuttings were collected at selected depths and drive samples were collected at intervals between 2.5 and 5 feet from the borings. The sampling was performed using Standard Penetration Test (SPT) samplers in accordance with ASTM D 1586 and Ring-Lined “California” Split Barrel samplers in accordance with ASTM D 3550. Bulk samples were collected from auger cuttings and placed in plastic bags. SPT drive samples were obtained using a 2-inch outside diameter and 1.375-inch inside diameter split-spoon sampler without lining. The soil recovered from the SPT sampling was sealed in plastic bags to preserve the natural moisture content. California drive samples were collected with a 3-inch outside diameter 2.5-inch inside diameter split barrel sampler with a 2.42-inch inside diameter cutting shoe. The sampler barrel is lined with 18-inches of metal rings for sample collection and has an additional length Appendix A - Geotechnical Investigation El Fuerte and Maerkle Motorized Valves Page A-2 Dudek Group Delta Project No. SD700 of waste barrel. Stainless steel or brass liner rings for sample collection are 1-inch high, 2.42- inch inside diameter, and 2.5-inch outside diameter. California samples were removed from the sampler, retained in the metal rings, and placed in sealed plastic canisters to prevent loss of moisture. At each sampling interval, the drive samplers were fitted onto sampling rod, lowered to the bottom of the boring, and driven 18 inches or to refusal (50 blows per 6 inches) with a 140-lb hammer free-falling a height of 30-inches using an automatic hammer. Compared to the SPT, the California sampler provides less disturbed samples. Penetration Resistance SPT blow counts adjusted to 60% hammer efficiency (N60) are routinely used as an index of the relative density of coarse-grained soils. For samples collected using non-SPT samplers, different hammer weight and drop height, and/or efficiency different than 60%, correction factors can be applied to estimate the equivalent SPT N60 value following the approach of Burmister (1948) as follows: N*60 = NR * CE * CH * CS Where: N*60 = equivalent SPT N60 NR = Raw Field Blowcount (blows per foot) CE = Hammer Efficiency Correction = Eri / 60% CH = Hammer Energy Correction = (W * H) / (140 lb * 30 in) CS = Sampler Size Correction = [(2.0 in)2-(1.375 in)2]/[Do2-Di2] Eri = hammer efficiency, % W= actual drive hammer weight, lbs H = actual drive hammer drop, inch Do, Di = actual sampler outside and inside diameter, respectively, inches Burmister’s correction assumes that penetration resistance (blowcount) is inversely proportional to the hammer energy. For a hammer other than a 140# hammer with 30” drop the hammer energy correction is equal to the ratio of the theoretical hammer energy (weight times drop) to the theoretical SPT hammer energy, or CH = (W * H) / (140 lb * 30 in). Burmister’s correction assumes that penetration resistance (blowcount) is proportional to the annular end area of the drive sampler. For California drive samplers with Do=3 inch and Di=2.42 inch the sampler size correction factor is the ratio of the annular area of an SPT split spoon to that of the California Sampler, or CS =[2.02-1.3752]/[32-2.422] = 0.67. Appendix A - Geotechnical Investigation El Fuerte and Maerkle Motorized Valves Page A-3 Dudek Group Delta Project No. SD700 To normalize the field SPT and California blowcounts to a hammer with 60% efficiency, an energy correction factor equal to Hammer Efficiency (%) / 60% was applied to the field blowcounts. Hammer efficiency was determined by Pile Driving Analyzer (PDA) measurement. Hammer efficiency measurements are presented in Figures A-3A through A-3C. The correction factors applied to obtain N*60 are summarized in the following table: Hammer Type Hammer Weight and Drop CH Hammer Efficiency (%) CE Cal Sampler Dimensions CS Combined Correction Factor SPT Samples Combined Correction Factor CAL Samples CME Auto 140# 30” 1 88.3 1.47 Do=3.0” Di=2.42” 0.67 1.47 0.99 Corrected N*60 are generally used, with due engineering judgment, only for qualitative assessment of in place density or consistency and are not used for other more critical analyses such as liquefaction. Relative Density and Consistency Equivalent SPT N60 values were used as the basis for classifying relative density of granular/cohesionless soils. Wherever possible consistency classification of cohesive soils was based on undrained shear strength estimated in the field with a pocket penetrometer or by testing in the laboratory. The correlations for consistency and relative density are shown in the Boring Record Legend Figure A-1C. Drive sample field blow counts, SPT N*60 values, pocket penetrometer readings, and corresponding density/consistency classifications are presented on the boring records. Borehole Abandonment At the completion of the drilling, the borings were abandoned by backfilling the borehole with drill cuttings. Notes describing the borehole abandonment are presented at the bottom of each boring record. Sample Handling and Transport Geotechnical samples were sealed to prevent moisture loss, packed in appropriate protective containers, and transported to the geotechnical laboratory for further examination and geotechnical testing. Appendix A - Geotechnical Investigation El Fuerte and Maerkle Motorized Valves Page A-4 Dudek Group Delta Project No. SD700 Laboratory Testing The soils were further examined and tested in the laboratory and classified in accordance with the Unified Soil Classification System following ASTM D 2487 and D 2488 (see Figures A-1D and A-1E). Field classifications presented on the records were modified, where necessary, based on the laboratory test results. Descriptions of the laboratory tests performed, and a summary of the results are presented in Appendix B.

SPT HAMMER ENERGY MEASUREMENTS Prepared by; SPT CAL 5512 Belem Dr Chino Hills, CA 91709 909-730-2161 bc@sptcal.com SPT CAL Figure A-3A PRESENTATION OF SPT ANALYZER TEST DATA 1.Introduction This report presents the results of SPT Hammer Energy Measurements recorded with an SPT Analyzer from Pile Dynamics carried out on June 12, 2020 near La Mesa, California. 2.Field Equipment and Procedures The drill used was Pacific Drillings Fraste track mounted drill. It has an attached Marl Automatic Hammer. It was attached to a winch cable which is lowered as the hammer drives the sample. The Marl Automatic Hammer uses a 140 lb. weight dropped 30” on to an internal anvil above the bore hole. The drill rod connects the anvil to a split spoon type soil sampler inside an 8” o.d. hollow stem auger at the designated sample depth. After a seeding blow the sampler is driven 18”. The number of blows required to penetrate the last 12" is referred to as the “N value”, which is related to soil strength. The first recording was taken at 5' below ground surface and then every 5' to final recording at 35’. 3.Instrumentation An SPT Analyzer from Pile Dynamics was used to record and the process the data. The raw data was stored directly in the SPT Analyzer computer with subsequent analysis in the office with PDA-W and PDIPlot software. The measurements and analysis were conducted in general accordance with ASTM D4945 and ASTM D6066 test standards. The SPT Analyzer is fully compliant with the minimum digital sampling frequency requirements of ASTM D4633-05 (50 kHz) and EN ISO 22476-3:2005 (100 kHz), as well as with the low pass filter, (cutoff frequency of 5000 Hz instead of 3000 Hz) requirements of ASTM D4633-05. All equipment and analysis also conform to ASTM D6066. A 2' instrumented section of AWJ rod, with two sets of accelerometers and strain transducers mounted on opposite sides of the drill rod, was placed below the anvil. It measured strain and acceleration of every hammer blow. The SPT Analyzer then calculates the amount of energy transferred to the rod by force and velocity measurements. Figure A-3B 4.Observations The drill rig motor is diesel fueled. The drill and sample equipment looked to be well operated and maintained. 5.Results Results from the SPT Hammer Energy Measurements are summarized below. It shows the Energy Transfer Ratio (ETR) at each sampling depth. ETR is the ratio of the measured maximum transferred energy to rated energy of the hammer which is the product of the weight of the hammer times the height of the fall. 140 lb x 30” = 4200 lb-in = 0.350 kip-ft. Energy Transfer Ratio = 88.3% at 30.5 blows per minute N60=(ETR/60)N If you have any questions please do not hesitate to call or email.ꢀ Thank you,ꢀ Brian Serl Calibration Engineer SPT CAL 909-730-2161 bc@sptcal.com Depth ETR%BPM 5 87.6 28.3 10 94.0 35.3 15 90.1 37.2 20 86.9 26.6 25 84.1 25.3 30 85.5 29.4 35 89.9 31.7 Average 88.3 30.5 Figure A-3C Appendix B Laboratory Testing APPENDIX B LABORATORY TESTING B.1 General The laboratory testing was performed using appropriate American Society for Testing and Materials (ASTM) and Caltrans Test Methods (CTM). Modified California drive samples, Standard Penetration Test (SPT) drive samples, and bulk samples collected during the field investigation were carefully sealed in the field to prevent moisture loss. The samples of earth materials were then transported to the laboratory for further examination and testing. Tests were performed on selected samples as an aid in classifying the earth materials and to evaluate their physical properties and engineering characteristics. Laboratory testing for this investigation included: • Soil Classification: USCS (ASTM D 2487) and Visual Manual (ASTM D 2488); • Moisture content (ASTM D 2216) and Dry Unit Weight (ASTM D 2937); • Grain Size Distribution (ASTM D 422) & % Passing #200 Sieve (ASTM D 1140); • Direct Shear (ASTM D 3080); • Expansion Index (D 4829); • Soil Corrosivity: o pH (CTM 643); o Water-Soluble Sulfate (ASTM D 516, CTM 417); o Water-Soluble Chloride (Ion-Specific Probe, CTM 422); o Minimum Electrical Resistivity (CTM 643); and • Laboratory Compaction Test (ASTM D 1557). Brief descriptions of the laboratory testing program and test results are presented below. B.2 Soil Classification Earth materials recovered from subsurface explorations were classified in general accordance with Caltrans’ “Soil and Rock Logging Classification Manual, 2010”. The subsurface soils were classified visually / manually in the field in accordance with the Unified Soil Classification System (USCS) following ASTM D 2488; soil classifications were modified as necessary based on testing in the laboratory in accordance with ASTM D 2487. The details of the soil classification system and boring records presenting the classifications are presented in Appendix A. B.3 Moisture Content and Dry Unit Weight The in-situ moisture content of selected bulk, SPT, and Ring samples was determined by oven drying in general accordance with ASTM D 2216. Selected California Ring samples Appendix B - Geotechnical Investigation El Fuerte and Maerkle Motorized Valves Page B-2 Dudek Group Delta Project No. SD700 were trimmed flush in the metal rings and wet weight was measured. After drying, the dry weight of each sample was measured, volume and weight of the metal containers was measured, and moisture content and dry density were calculated in general accordance with ASTM D 2216 and D 2937. Results of these tests are presented on the boring records in Appendix A. B.4 Grain Size Distribution and Percent Passing No. 200 Sieve: Representative samples were dried, weighed, soaked in water until individual soil particles were separated, and then washed on the No. 200 sieve. The percentage of fines (soil passing No. 200 sieve) was determined for selected samples in accordance with ASTM D 1140. For selected samples, the washed material retained on No. 200 sieve was shaken through a standard stack of sieves in accordance with ASTM D 422 to determine the grain size distribution. The results of grain size distribution tests are plotted in Figures B-1A through B-1B of this appendix. The relative proportion (or percentage) by dry weight of gravel (retained on No. 4 sieve), sand (passing No. 4 and retained on No. 200 sieve), and fines (passing No. 200 sieve) are listed on the boring records in Appendix A. B.5 Direct Shear Test To determine the drained shear strength parameters of the on-site soils, direct shear tests were performed on selected compacted remolded samples in accordance with ASTM D 3080. After the initial weight and volume measurements were made, the sample was placed in the shear machine, and a selected normal load was applied. The sample was saturated or kept at field moisture (to model worst case field conditions), allowed to consolidate under the selected normal load, and then sheared to failure. Shear rate was selected to maintain drained conditions. Shear stress and vertical/horizontal sample deformations were monitored throughout the test. The process was repeated on additional samples of the same soil material at two additional normal loads. The test results are presented in Figure B-2A of this appendix. B.6 Expansion Index The expansion potential of the site soils was estimated using the Expansion Index Test in accordance with ASTM D 4829. The results of this test are listed on the boring records in Appendix A. B.7 Soil Corrosivity Tests were performed in order to determine corrosion potential of site soils on concrete and ferrous metals. Corrosivity testing included minimum electrical resistivity and soil pH (Caltrans method 643), water-soluble chlorides (Orion 170A+ Ion Probe), and water-soluble Appendix B - Geotechnical Investigation El Fuerte and Maerkle Motorized Valves Page B-3 Dudek Group Delta Project No. SD700 sulfates (ASTM D 516). The test results are summarized presented in Figure B-3A of this appendix. B.8 Laboratory Compaction Test The laboratory maximum dry density and optimum water content for compacted soils were determined in accordance with ASTM D 1557. Results of the tests are presented in Figure B-4A through B-4B.

For the CIP projects proposed in close proximity to a known cultural resource or projects that would result in ground-disturbing activities in a previously undisturbed area, a project-level cultural resources investigation shall be conducted by a qualified cultural resource professional as defined in the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017) (2017 Guidelines) The cultural resources investigation shall include: 1. A CIP project site-specific review of the records search data at the South Coastal Information Center shall be conducted to determine if the CIP project site has been subjected to a professional survey. a. If a current cultural resources report addressing potential impacts on cultural resources is available, the city or CMWD shall implement the mitigation measures provided within the report. In the event that a current and valid report is not available, or if the entirety of the CIP project site has not been professionally surveyed, then an updated records search shall be performed. b. In accordance with the 2017 Guidelines, the city or CMWD shall contact the NAHC and local tribal governments for input on the project in order to identify any additional Native American resources that may not be included in the records search. 2. For those CIP project site(s) not addressed by a current cultural resources report (produced within five years of project proposal), a project-level Phase I Cultural Resources Survey shall be prepared in accordance with the 2017 Guidelines. Updates for all resources encountered during the Phase I survey shall be recorded using Department of Parks and Recreation (DPR) 523 forms in accordance with all applicable regulations. Resources shall be evaluated for significance and eligibility for inclusion in all applicable historic registers using methods such as, but not limited to, subsurface testing and/or archival research. Any subsurface testing would be monitored by an appropriate Native American representative. 3. In the event that such resources are found to be historical resources pursuant to CEQA, potential adverse impacts must be analyzed as stated in PRC Sections 21084.1 and 21083.2(l). Suitable mitigation for significant effects on archaeological resources are outlined in Section 15126.4(b)(3) as well as the 2017 Guidelines. The city or CMWD shall be responsible for implementing the methods for eliminating or substantially reducing impacts on resources as recommended by the archeologist and in consultation with the Native American Tribe. Such methods could include, but are not limited to: a. Planning construction to avoid archaeological sites; b. Incorporation of sites within parks, greenspace, or other open space; c. Capping or covering a site with a layer of soil before building on the site; d. Deeding the site into a permanent conservation easement; e. Excavation (Data Recovery) of archaeological resources; and/or f.

Exhibit “EIR-B” August 2019 City of Carlsbad Sewer Master Plan and Page 11 CMWD Water and Recycled Water Master Plans Program EIR & Addendum (EIR 12-01) Project Design Features Aesthetics The following measures would be implemented into the design and construction of CIP projects to minimize potential effects on aesthetics to neighborhoods surrounding the CIP projects: • Demolition debris will be removed in a timely manner for off-site disposal. • Tree and vegetation removal will be limited to those depicted on construction drawings. • Construction lighting will be shielded or directed away from adjacent residences. • All roadway features (signs, pavement delineation, roadway surfaces, etc.) and structures within state and private rights-of-way will be protected, maintained in a temporary condition, or restored. • Disturbed areas will be restored following construction consistent with original site conditions and surrounding vegetation. If removed vegetation included invasive plant species, the restored area shall be revegetated with a mix of native, non-invasive plants that are compatible with the surrounding setting. If necessary, a temporary irrigation system will be installed and maintained by the city or CMWD, or watering trucks will be used at a frequency to be determined by the city or CMWD to maintain successful plant growth. For proposed CIP pipeline projects that would require trenching or that would require the temporary removal of concrete or asphalt, the disturbed area will be repaved to be consistent with the existing material. • Above-ground components such as pump stations will be designed with exterior fencing, paint, and vegetative screening to reduce aesthetic impacts in visually sensitive areas. Air Quality The following BMPs would be implemented to minimize fugitive dust emissions and other criteria pollutant emissions during construction of CIP projects: • Water or dust control agents will be applied to active grading areas, unpaved surfaces, and dirt stockpiles as necessary to prevent or suppress particulate matter from becoming airborne. All soil to be stockpiled over 30 days will be protected with a secure tarp or tackifiers to prevent windblown dust. • Covering/tarping will occur on all vehicles hauling dirt or spoils on public roadways unless additional moisture is added to prevent material blow-off during transport. • Dirt and debris spilled onto paved surfaces at the project site and on the adjacent roadway will be swept or vacuumed and disposed of at the end of each workday to reduce resuspension of particulate matter caused by vehicle movement. During periods of soil export or import, when there are more than six trips per hour, dirt removal from paved surfaces will be done at least twice daily. • Disturbed areas will be revegetated as soon as work in the area is complete. • Electrical power will be supplied from commercial power supply wherever feasible, to avoid or minimize the use of engine-driven generators. Exhibit “EIR-B” August 2019 City of Carlsbad Sewer Master Plan and Page 12 CMWD Water and Recycled Water Master Plans Program EIR & Addendum (EIR 12-01) • Air filters on construction equipment engines will be maintained in clean condition according to manufacturers’ specifications. • The construction contractor will comply with an approved traffic control plan to reduce non- project traffic congestion impacts. Methods to reduce construction interference with existing traffic and the prevention of truck queuing around local sensitive receptors will be incorporated into this plan. • Staging areas for construction equipment will be located as far as practicable from residences. • Trucks and equipment will not idle for more than 15 minutes when not in service. Biological Resources The BMPs identified in the City of Carlsbad HMP would be implemented during the construction and operation of CIP projects to minimize potential effects on biological resources: • Use BMPs to prevent pollution generated by construction activities from entering surface and groundwater. BMPs will also ensure that non-stormwater discharges are not discharged into stormwater drainage systems. BMPs may include: o Regulatory measures such as erosion control ordinances and floodplain restrictions. o Structural measures such as detention or retention basins, filters, weirs, check dams, or drainage diversions. o Vegetative controls that reduce volume and accomplish pollutant removal by a combination of filtration, sedimentation, and biological uptake. o Maintenance of pump stations, sewer lines, and stormwater conveyance systems. o Cultural practices such as restrictions on pesticide and fertilizer applications, storage or disposal of toxic chemicals, or washing of vehicles or equipment in areas that can drain to the estuary. o Public education programs that educate residences about proper disposal of oil or chemicals and that provide opportunities (e.g. designated locations) for residents to properly dispose of contaminants. • For clearing, grading, and other construction activities within the watershed, ensure that proper irrigation and stormwater runoff mitigation measures are employed to reduce sediment loads and to prevent contamination from pesticide, fertilizers, petroleum products, and other toxic substances. • Restrict or limit recreational or other activities within 500 feet of important forage, breeding, and roosting areas. • Require attenuation measures for activities that generate noise levels greater than 60 dBA if occurring within 500 feet of important breeding habitat during the nesting season. • Restrict construction hours to daytime hours that do not require the use of construction lighting. Exhibit “EIR-B” August 2019 City of Carlsbad Sewer Master Plan and Page 13 CMWD Water and Recycled Water Master Plans Program EIR & Addendum (EIR 12-01) Cultural and Paleontological Resources The following procedure for unintentional disturbance of cultural resources will be implemented to minimize impacts to previously unknown archaeological resources during construction of CIP projects: If subsurface cultural resources are encountered during CIP project construction, or if evidence of an archaeological site or other suspected cultural resources are encountered, all ground- disturbing activity will cease within 100 feet of the resource. A qualified cultural resource professional, as defined in the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017) (2017 Guidelines), will be retained by the city or CMWD to assess the find, and to determine whether the resource requires further study. The assessment shall include consultation with the NAHC or Native American Tribe. Any previously undiscovered resources found during construction will be recorded on appropriate Department of Parks and Recreation (DPR) 523 forms and evaluated by a qualified cultural resource professional retained by the city or CMWD for significance under all applicable regulatory criteria. No further grading will occur in the area of the discovery until the city and CMWD approves the measures to protect the resources. Geology and Soils The following measures will be implemented into the construction and operation of CIP projects to minimize potential risks from geologic and soil hazards: • A site-specific geotechnical investigation will be completed during the engineering and design of each CIP project that would require excavation in previously undisturbed soil, which would determine the risk to the project associated with fault rupture, groundshaking, liquefaction, landslides, and expansive soils. The geotechnical investigations will describe site-specific conditions and make recommendations that will be incorporated into the construction specifications for the CIP project. Recommendations may include, but would not be limited to the following typical measures: o Over-excavate unsuitable materials and replace them with engineered fill. o Remove loose, unconsolidated soils and replace with properly compacted fill soils, or apply other design stabilization features. o For thicker deposits, implement an applicable compaction technique such as dynamic compaction or compaction piles. o Perform in-situ densification of soils or other alterations to the ground characteristics. o For landslides, implement applicable techniques such as stabilization; remedial grading and removal of landslide debris; or avoidance. Hazards and Hazardous Materials The following measures would be implemented into the construction and operation of CIP projects to minimize potential effects related to hazards and hazardous materials: • Fire safety information will be disseminated to construction crews during regular safety meetings. Fire management techniques will be applied during project construction as deemed necessary by the lead agency and depending on-site vegetation and vegetation of surrounding areas. • A brush management plan will be incorporated during project construction by the city, CMWD, or a contractor, as necessary. Construction within areas of dense foliage during dry conditions will be avoided, when feasible. Exhibit “EIR-B” August 2019 City of Carlsbad Sewer Master Plan and Page 14 CMWD Water and Recycled Water Master Plans Program EIR & Addendum (EIR 12-01) • In cases where avoidance is not feasible, necessary brush fire prevention and management practices will be incorporated. Specifics of the brush management program will be determined as site plans for the project are finalized. • A site-specific hazardous materials record search for the locations and type of hazardous materials for the site will be done and, if required, a site assessment will be conducted during final design of individual CIP project components. • In order to ensure that the project does not cause a significant hazard to the public or the environment through release of or transport of hazardous materials during construction and operation, the city, CMWD, or a contractor, will implement the following project design features: o Pipelines of the project components would be constructed with polyvinyl chloride pipe, or other material, which is highly resistant to rupture. o Pump stations included as part of the project, and stations that will service the proposed project will be designed or constructed with safety features, including an emergency generator on site in case of electrical failure, and sufficient sewage detainment capacity in the event of generator and/or pump mechanism failure to allow time for repair and/or emergency conveyance of the sewage. Portable emergency generators may be used for pump stations that cannot be equipped with an on-site generator. Should emergency leaks or spills occur, the Sewer Prevention and Response Plan for both the city and the CMWD will be implemented. Hydrology and Water Quality The following measures would be implemented into the construction and operation of CIP projects to minimize potential effects to hydrology and water quality: • A construction spill contingency plan will be prepared for new facilities in accordance with County Department of Environmental Health regulations and retained on site by the construction manager. If soil is contaminated by a spill, the soil will be properly removed and transported to a legal disposal site. • If groundwater is encountered and dewatering is required, then the groundwater will be disposed of by pumping to the sanitary sewer system or discharging to the storm drain system according to the conditions of the appropriate discharge permit. • The lead agencies will consider using pervious or semi-pervious surfaces where possible to reduce the increase in the velocity of peak flows. • For all potential impacts to natural drainages (i.e., pre-development hydrology), BMPs on site will be used to fully mitigate for project-related contaminants in the surface flows prior to their discharge to streams. • For all trenchless construction activities, the city or CMWD will implement the following methods recommended by the CDFG and USFWS to prevent water pollution: o Implementation of the following techniques to reduce potential for hydrofracture and inadvertent returns that could pollute nearby water:  Sufficient earth cover will be used to increase resistance to hydrofracture. Exhibit “EIR-B” August 2019 City of Carlsbad Sewer Master Plan and Page 15 CMWD Water and Recycled Water Master Plans Program EIR & Addendum (EIR 12-01)  An adequately dense drilling fluid will be used to avoid travel of drilling fluid in porous sands.  The bore will be conducted in a manner that avoids collapse.  Borehole pressure will be maintained at levels low enough to avoid hydrofracture.  Reaming and pullback rates will be maintained at rates slow enough to avoid over- pressurization of the bore.  The surface above the vicinity of the drill head will be visually monitored for surface evidence of hydrofracture.  Drilling methods will be modified to suit site conditions such that hydrofracture does not occur. o Hydrofractures will be cleaned immediately after they occur. Necessary response equipment will be readily accessible and in good working order. o Hydrofracture reporting and cleanup information will be disseminated to construction crews during regular safety meetings. All field personnel will understand their responsibility for timely reporting of hydrofractures. Noise The following measures would be implemented into the construction and operation of CIP projects to minimize noise effect to surrounding neighborhoods: • Heavy equipment will be repaired at sites as far as practical from nearby residences. • Construction equipment, including vehicles, generators and compressors, will be maintained in proper operating condition and will be equipped with manufacturers’ standard noise control devices or better (e.g., mufflers, acoustical lagging, and/or engine enclosures). • Construction work, including on-site equipment maintenance and repair, will be limited to the hours specified in the noise ordinance of the affected jurisdiction. • Electrical power will be supplied from commercial power supply, wherever feasible, in order to avoid or minimize the use of engine-driven generators. • Staging areas for construction equipment will be located as far as practicable from residences. • Operating equipment will be designed to comply with all applicable local, state, and federal noise regulations. • If lighted traffic control devices are to be located within 500 feet of residences, the devices will be powered by batteries, solar power, or similar sources, and not by an internal combustion engine. • The city, CMWD or a construction contractor will provide advance notice, between two and four weeks prior to construction, by mail to all residents or property owners within 300 feet of the alignment. For projects that would require pile driving or blasting, noticing will be provided to all residents or property owners within 600 feet of the alignment. The announcement will state specifically where and when construction will occur in the area. If construction delays of more than 7 days occur, an additional notice will be made, either in person or by mail. • The city or CMWD will identify and provide a public liaison person before and during construction to respond to concerns of neighboring residents about noise and other construction disturbance. The city or CMWD will also establish a program for receiving questions or complaints during Exhibit “EIR-B” August 2019 City of Carlsbad Sewer Master Plan and Page 16 CMWD Water and Recycled Water Master Plans Program EIR & Addendum (EIR 12-01) construction and develop procedures for responding to callers. Procedures for reaching the public liaison officer via telephone or in person will be included in notices distributed to the public in accordance with the information above. • For any construction activities which include blasting, a qualified blasting consultant and geotechnical consultant will prepare all required blasting plans and monitor all blasting activities in conformance with the Standards of the California Department of Mines. Transportation/Traffic The following measures would be implemented during construction of CIP projects to minimize traffic effects to surrounding neighborhoods: • Prior to construction, the city or CMWD will prepare a traffic control plan and coordinate with the cities of Oceanside, Vista, and San Marcos to address traffic during construction of project components within the public rights-of-way of the affected jurisdiction(s), including bicycle, pedestrian, and transit facilities. The traffic control plan will include signage and flagmen when necessary to allow the heavy equipment to utilize residential streets. The traffic control plan will also include provisions for coordinating with local school hours and emergency service providers regarding construction times.

The current Sewer, Water, and Recycled Water Master Plans (Master Plans), adopted in November 2012, were evaluated in a program environmental impact report (PEIR) prepared and certified by the city (State Clearinghouse [SCH] No. 2012021006). The Master Plans were updated in 2019 and an Addendum to the PEIR (2019 Addendum) was prepared to address the changes from the 2012 PEIR. The proposed Project would update improvements included as part of the Water Master Plan. The city and CMWD are responsible for the maintenance, operations, and management of sanitary sewer collection systems, and water and recycled water distribution systems in their respective service areas. The Master Plans represent comprehensive programs for the phased and orderly development of sewer, water, and recycled water infrastructure in response to future demands within the respective service areas. They consist of projects incorporated into a Capital Improvement Program (CIP) to construct new facilities and modify or expand existing facilities. The 2012 PEIR and 2019 Addendum analyzed the potential physical impacts to the environment that would result from those improvements. This addendum is prepared in accordance with the California Environmental Quality Act (CEQA) (Public Resources Code §21000, et. seq.) and the CEQA Guidelines, as amended (California Administrative Code, Title 14, §15000, et. seq.). 1.1 Applicability and Use of Addendum The 2012 PEIR contemplated the idea of “tiering” from the document to allow for subsequent environmental documents to focus on those issues specific to the later project which were not addressed in the PEIR. In particular, the environmental documents for a later project would focus on the environmental effects which are capable of being integrated or were not analyzed as significant effects on the environment in the PEIR. In effect, tiering enables agencies to analyze environmental issues that are ready for decision at each stage, and to exclude issues that have already been decided or that are not ready for decision. The city and CMWD’s intent through preparation of this addendum is to demonstrate whether the previously adopted CEQA documents (2012 PEIR and 2019 Addendum), including mitigation measures, are still both adequate and valid for the proposed Project. Pursuant to Public Resources Code Section 21166 and the CEQA Guidelines, Sections 15162 through 15164, the city as the CEQA lead agency is required to conduct a fact-based evaluation of proposed changes to the Master Plan to determine whether supplemental environmental documentation is required. CEQA Guidelines, Section 15162(a), states that when an Environmental Impact Report (EIR) is certified for a project, no subsequent EIR shall be prepared for that project unless the lead agency determines that one of the conditions described in Section 15162(a) has occurred. Section 15164(a) provides that an addendum is appropriate if none of the conditions described in Section 15162(a) have occurred. Based on the analysis set forth in this addendum, the city and CMWD have concluded that the proposed Project does not trigger any of these circumstances, and that an addendum is the appropriate form of documentation to comply with CEQA. El Fuerte/Maerkle Motorized Valves Project 2 1.2 Format of This Addendum The PEIR and 2019 Addendum serve as the environmental compliance documents for the proposed Project, and this addendum provides additional clarification and information about the specific updates to the city’s Water Master Plan. This addendum should be read together with the full text of the previously certified PEIR (2012a) and 2019 Addendum. Mitigation measures and project design features from the PEIR and 2019 Addendum, as provided in the Project-specific Mitigation Monitoring and Reporting Program (MMRP) found in Chapter 5 of this addendum, are incorporated by reference into this addendum. In addition, the addendum incorporates by reference the city’s General Plan Update, supporting PEIR (2015a), and Climate Action Plan (2015b). This addendum relies on the use of an Environmental Checklist Form (Checklist), as suggested in Section 15063(d)(3) of the CEQA Guidelines, as amended. 1.3 Summary of Findings Based upon the Checklist prepared for the proposed Project and supporting responses (Section 4), implementation of the proposed Project would not result in substantial changes requiring major revisions to the PEIR. Further, the proposed Project would not result in any environmental impacts that have not already been addressed in the PEIR, and no new mitigation measures are required. Since only minor additions and clarifications are required to the PEIR, and none of the conditions described in Public Resources Code Section 21166 or CEQA Guideline Section 15162 have occurred, the city and CMWD finds that the preparation of an addendum to the PEIR is appropriate and consistent with Public Resources Code Section 21166 and CEQA Guidelines Sections 15162-15164. 1.4 Lead Agency and Discretionary Approvals This addendum and the PEIR are intended to serve as the environmental documentation for the proposed Project. The City of Carlsbad is the lead agency under CEQA and maintains authority to approve the addendum. 2.0 Description of the Proposed Project CMWD is currently proposing improvements to previously identified water CIP projects, the El Fuerte and Maerkle Motorized Valves Project (collectively referred to as the Project or Projects). 2.1 Project Locations The proposed Project improvements are generally located in the northern part of San Diego County within the City of Carlsbad (Figure 1, Regional Location). The El Fuerte Motorized Valve site is located within El Fuerte Street and a 300 square foot easement (Assessor’s Parcel Number [APN] 222-600-01). The valve location is north of the intersection with Rancho Pancho and the corrosion test stations are located between Rancho Pancho and Alga Road, as show in Figure 2, Project Locations. The easement area has a General Plan land use designation of Community Facilities and is zoned as Planning Community – Rancho Carrillo Master Plan – Village T (Community Facility). !!!! !!! ! !!!!!! !!!! !! !!!! !!! !!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!! !!!!!!!! !!!!!! !!!!!!!! !! !!!! !! !!!!!! !!!!!!!! !! !! ! ! !! !! !!!! ! ! !!!! !! !! !!!!!!!!!! !! !!!!!!! !!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! !!!! !!!! !!!!!!!!!!!!! !!!!!!!! !!!!!!!!!!!!!!!!!!! !!!!!!!! !! !!!!!! !!!!!!!!!! ! !! !!!! !! !!!!!! !!!!!! !!! !!!!!! !!!! !!!!!!!! !!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!! !! !!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!! !! !!!!!!!! !!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! ! ! ! ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! !!!!!!!!!!!!!!!!!!!!!!!!WÊ !"^$ !"^$ !"^$ !"^$ WÌ WÌ !"_$ !"_$ !"a$ !"a$ !"a$ ?n ?p ?p ?t ?¦ ?¦ ?³ ?¸ ?¸ ?¸ ?¹ ?¹ ?Ë ?Ë Aä Aä Ag %&s( %&s( %&u(!Maerkle Site !El Fuerte Site POWAY OCEANSIDE CARLSBAD VISTA ESCONDIDO OTAY CHULA VISTA SANTEE SANMARCOS ENCINITAS EL CAJON LA MESA CORONADO NATIONAL CITY IMPERIAL BEACH LEMON GROVE SOLANA BEACH DEL MAR SANDIEGO CAMP PENDLETON Lake San Marcos Lake Hodges Lake Wohlford Lake Ramona Lake Poway Miramar Reservoir San Vicente Reservoir Lake Murray Sweetwater Reservoir Lake Jennings Otay Reservoir Pacific Ocean San D iego BaySantee Lakes Sutherland Reservoir Lake Henshaw El Capitan Reservoir Loveland Reservoir Vail Lake O'Neill Lake Barrett Lake TIJUANA UNITED STATES MEXICO DULZURA JULIAN RAMONA WARNERSPRINGS RIVERSIDECOUNTY ORANGECOUNTY SAN DIEGOCOUNTY ALPINELAJOLLA ?¹ FALLBROOK Figure 1 Regional LocationI:\PROJECTS\C\CarlsbadMunicipalWD_01174\00005_CMWDTerramar\005_TerramarSewerWaterMainImpCEQA\Map\Addendum\Addendum.aprx 01174.00005.005 10/27/2022 - DYSource: Base Map Layers (SanGIS, 2016)K El Fuerte/Maerkle Motorized Valves Project 0 8 Miles !. !. !. !. !. ! ! ! ! ! !. !. !. !. !.

Rancho P a n c h o ElFuerteSt Alga RdEl Fue r te St El Fuerte/Maerkle Motorized Valves Project 3 The Maerkle Motorized Valve site is located near Sunny Creek Road, close to the Maerkle Reservoir (see Figure 2). The site is located within parcel (APN 760-166-86-00) that has a land use designation and zoning of Open Space. 2.2 Project Description I. El Fuerte The El Fuerte Motorized Valve Project involves the installation of a new valve vault, 24-inch and 30-inch diameter steel piping, a motorized valve and cathodic protection improvements on the existing 30-inch steel water transmission main in El Fuerte Street. The new motorized valve would replace an existing valve located on the boundary of two water pressure zones at the intersection with Rancho Pancho and is used to ensure adequate water supply and water quality in the system. The new valve would be installed in a new underground vault and easement, outside of the road under portions of the sidewalk and landscape, to facilitate access and to improve worker safety. Corrosion test stations would be installed at five locations along the pipeline in El Fuerte Street. The work would involve trenching excavation in asphalt concrete pavement, concrete sidewalk, and ornamental landscape to remove and replace portions of the 30-inch piping and to install an approximately 8-foot-deep valve vault. Installation of the corrosion test stations would involve minor trenching in the roadway to install wiring and at-grade covers behind the sidewalk for test station access. The El Fuerte Motorized Valve Project was included as CIP Project Number W-13 in the 2019 Addendum as well as the PEIR as Project 21. Cathodic protection projects, such as the proposed corrosion test stations, were included in the 2019 Addendum as project 50071 under the Asset Management Program. II. Maerkle The Maerkle Motorized Valve Project is located near the Maerkle Reservoir and involves the replacement of two existing isolation valves and piping with new motorized valves and piping, which would automate water system operations. The existing 24-inch and 42-inch valves divert water into the 10-million-gallon tank and the 200-million-gallon reservoir. The new valves would be installed in a new underground vault at the base of the slope to make it easier to access the valves and to improve worker safety. The work would involve trenching excavation to remove and replace the 24-inch and 42-inch valves and piping, along with the installation of an approximately 12-foot-deep new vault. Approximately 2,400 square feet of ground could potentially be affected, though the ground has been previously disturbed from the installation of large diameter pipelines and construction of the existing 10-million- gallon tank, and some of which is a walking path to the existing valves for operation. Facility improvements at the Maerkle Reservoir are included as CIP project W-9 (50091) in the 2019 Addendum, as well as the PEIR as project R7. However, the improvements were described in the PEIR as replacing joint sealing in the 10-million-gallon tank and adding security lights and cameras along the access road, gates, and site. Excavation and/or ground disturbance was not anticipated at the time. El Fuerte/Maerkle Motorized Valves Project 4 2.3 Construction Methods Construction of the Projects is scheduled to begin between early 2023 and early 2024. The El Fuerte and Maerkle Motorized Valve improvements are planned to be constructed under a single contract and would be constructed simultaneously or in close succession. Construction would involve open trench methods, utilizing typical construction equipment such as dozers, rollers, dewatering pumps, backhoes, loaders, delivery, and haul trucks. 2.4 Regulatory Compliance As described in PEIR Chapter 2.6.1, Regulatory Compliance, construction and operation of the CIP projects would be conducted in compliance with all applicable federal, state, and local laws and regulations. Updates to the original description are provided based on changes in existing conditions described in the PEIR. Since the certification of the PEIR, the National Pollutant Discharge Elimination System (NPDES) Permit and Waste Discharge Requirements for Discharges from the Municipal Separate Storm Sewer Systems Draining the Watersheds within the San Diego Region (Order No. R9-2013-0001, NPDES No. CAS0109266) were amended. The updated permit requires projects not falling within the triggering coverage thresholds of the General Permit to comply with the implementing ordinances of the county and cities bound by the Municipal Separate Storm Sewer Systems permit in which the improvements are located. 2.5 Project Design Features As part of the PEIR and 2019 Addendum, CMWD incorporates several project design features and construction measures into the Project designs in an effort to reduce the potential for adverse environmental effects. These features are incorporated by reference from Chapter 2.6.2, Project Design Features, of the PEIR. The project design features are also provided in the MMRP. 3.0 Environmental Setting This section incorporates by reference Chapter 3, Environmental Setting, from the PEIR and the 2019 Addendum, as applicable. This section focuses on the Water Service and Master Plan, as the proposed Project improvements are related to potable water service. 3.1 Existing Water Service and Master Plan (including 2019 Addendum) Originally, the Water Master Plan was approved in 1990 with recommendations and revisions prepared in 1997 and adopted with the 2003 update. The 2003 Water Master Plan Update evaluated the CMWD water distribution system and its ability to meet project demands. Since the Master Plan Update in 1997, a substantial number of residential, commercial, and industrial developments had been constructed and future development had been identified in the 2001 Growth Management Database. The 2003 document presented an update of CMWD’s Water Master Plan for the planning period El Fuerte/Maerkle Motorized Valves Project 5 between 2001 and buildout of the CMWD’s service area, which was anticipated to occur by 2020. CMWD reviewed all infrastructures within the service area to identify necessary improvements to existing facilities, capacity improvements, and expansion needs. An update to the Water Master Plan was prepared in 2012 and analyzed in the PEIR. The update included a capacity evaluation to meet future demands and recommended CIP projects for continued reliable water service through buildout in accordance with the Carlsbad Growth Management Plan. Considering the significant projected buildout, potable water demand was anticipated to increase 8 percent from 19.1 million gallon per day (mgd) (21,392 acre feet per year [afy]) in 2007 to 20.8 mgd (23,296 afy) in 2035. Between 2035 and 2050, water demand was projected to increase three percent to 21.4 mgd (23,968 afy). The Water Master Plan was again updated in 2019 based on more recent demand forecasts and hydraulic modeling. A median water demand forecast of 20,700 afy or 18.5 mgd at buildout (2040) was used as the basis for the 2109 Water Master Plan Update. This projection was lower than the 2035 forecast used in the 2012 Water Master Plan (CMWD 2012b). Water service is provided by the CMWD, encompassing approximately 83 percent of Carlsbad. The remaining areas are serviced by the Olivenhain Municipal Water District in the southern portion and Vallecitos Water District in the eastern portion of the city. The CMWD receives 100 percent of its potable water supply from the San Diego County Water Authority, delivering water through 450 miles of pipeline, 71 pressure regulating stations, five pump stations, eight storage tanks, and one earthen dam reservoir. The total operational storage for CMWD is 244 million gallons, which includes the 195-million- gallon Maerkle Reservoir. 3.2 Local and Regional Planning Context This section incorporates by reference Chapter 3.3, Local and Regional Planning Context, from the 2012 PEIR and 2019 Addendum. I. City of Carlsbad General Plan (2015a) The Carlsbad General Plan contains nine elements, with each element containing maps and figures, policy statements, over-arching goals, specific objectives, implementing programs, and in some instances, development standards. The Land Use and Community Design Element emphasizes the Growth Management Plan requiring that adequate public facilities are provided concurrent with new growth, specifically identifying performance standards for 11 public facilities: city administration, library, wastewater treatment, parks, drainage, circulation, fire, open space, schools, sewer collection, and water distribution. The Sustainability Element encourages conservation and reduced reliance on imported water. II. City of Carlsbad CAP The City of Carlsbad has developed a Climate Action Plan (CAP) to help the city meet state goals for reducing greenhouse gases and the community’s goal of promoting a sustainable environment. The CAP serves as a long-range strategy to reduce emissions of greenhouse gases, which include carbon dioxide, methane, nitrous oxide, and water vapor. The CAP sets a baseline for past and current emissions, forecasts future emissions, and establishes targets to reduce the intensity of greenhouse gas (GHG) El Fuerte/Maerkle Motorized Valves Project 6 emissions from water utilities (including water supply, wastewater, and recycled water) conveyance, treatment, and distribution by 8 percent by 2035. 4.0 Environmental Analysis Checklist 4.1 Environmental Analysis Checklist Summary The following Environmental Analysis Checklist (Checklist) (Table 4-1) was developed for projects with previously certified/approved environmental documents. This Checklist takes into consideration the preparation of an environmental document prepared at an earlier stage of a project (e.g., the PEIR for the Sewer, Water and Recycled Water Master Plans, certified in 2012, and the 2019 Addendum for the Master Plans updates), evaluates the adequacy of the earlier document in assessing potential environmental impacts resulting from the Projects, and is consistent with Section 21166 of the Public Resources Code and Section 15162 of the CEQA Guidelines. The results of this evaluation are summarized below with the detailed analysis provided in subsequent sections, including updated impact determinations.1 Table 4-1 ENVIRONMENTAL ANALYSIS CHECKLIST SUMMARY Environmental Issue Area Was Impact Analyzed in Prior Environmental Document(s)?

If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? Yes No No No d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Yes No No No a) Have a substantial adverse effect on a scenic vista? The potential impacts of the proposed Projects on scenic vistas were analyzed in the PEIR (Section 4.1) and 2019 Addendum. Impacts to scenic vistas could occur from construction activities, including disturbance of ground cover, grading, excavation, trenching, material stockpiles, and the presence of construction equipment. The majority of the proposed Project improvements would be contained to the public road right-of-way and located underground or co-located with existing storage facilities, resulting in minimal impacts to scenic vistas. The proposed Project improvements would be contained in generally urbanized landscapes and public rights-of-way and would not have a substantial adverse effect on scenic vistas. No substantial new information has been presented that shows the Project improvements would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? The potential impacts of the proposed Projects on scenic highways were analyzed in the PEIR (Section 4.1) and 2019 Addendum. There are no designated State Scenic highways in Carlsbad; therefore, no impacts related to scenic highways would occur (California Department of Transportation 2019). However, Interstate 5 is an eligible State Scenic highway and Carlsbad has its own scenic roadways program. Additionally, local scenic roadways are recognized by Carlsbad’s General Plan (2015a) including El Camino Real, Carlsbad Boulevard, Palomar Airport Road, La Costa Avenue, Melrose Drive, College Boulevard, Cannon Road, Carlsbad Village Drive, Faraday Avenue, Interstate 5, La Costa Avenue, Olivenhain Road/Rancho Santa Fe Road, and Poinsettia Lane/Carrillo Way, Adams Street/Park El Fuerte/Maerkle Motorized Valves Project 9 Drive, Batiquitos Drive, and Jefferson Street (the portion adjacent to the Buena Vista Lagoon). The Atchison, Topeka, and Santa Fe Railroad line is also considered a scenic corridor. The Project locations would not be visible from a scenic corridor. As incorporated in the PEIR, the Projects would be required to follow project design features, including the following: • Demolition debris will be removed in a timely manner for off-site disposal; • Tree and vegetation removal will be limited to those depicted on construction drawings; and • Disturbed areas will be restored following construction consistent with original site conditions and surrounding vegetation. If removed vegetation included invasive plant species, the restored area shall be revegetated with a mix of native, non-invasive plants that are compatible with the surrounding setting. Implementation of these project design features and compliance with federal, state, and local requirements and regulations would limit the visibility of construction activities. The proposed Project improvements would be contained in urbanized landscapes and beneath public rights-of-way and would not have a substantial adverse effect on scenic highways given they would not be visible from these corridors. No substantial new information has been presented that shows the Projects would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? The potential impacts of the proposed Projects on the existing visual character of the city landscape were analyzed in the PEIR (Section 4.1) and 2019 Addendum. Impacts to scenic vistas could occur from construction activities, including disturbance of ground cover, grading, excavation, trenching, material stockpiles, and the presence of construction equipment. Project improvements are mostly below-ground valve installations, with the exception of access points. Following construction, there would be no substantial change to scenic quality from existing conditions. The proposed Projects would not have a substantial adverse effect on the existing visual character of the city. No substantial new information has been presented that shows the Projects would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. d) Create a new source of substantial light or glare that would adversely affect day or nighttime views in the area? The potential glare and nighttime lighting impacts of the proposed Projects were analyzed in the PEIR (Section 4.1) and 2019 Addendum. The proposed Projects involve valve replacements and corrosion test station installation, which do not include any new lighting sources. The proposed Projects would not El Fuerte/Maerkle Motorized Valves Project 10 have a substantial adverse effect on existing sources of daytime glare or nighttime lighting. No substantial new information has been presented that shows the proposed Projects would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. II. Agriculture and Forestry Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use? Yes No No No b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? Yes No No No c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code Section 4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))? Yes No No No d) Result in the loss of forest land or conversion of forest land to non-forest use? Yes No No No e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non- forest use? Yes No No No El Fuerte/Maerkle Motorized Valves Project 11 a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? The potential impacts of the proposed Projects to important farmlands are analyzed in the PEIR (Section 5.1) and 2019 Addendum. As provided, there are only a limited number of areas within Carlsbad that include important farmlands as defined by the California Department of Conservation with the city consisting mainly of Urban and Built-Up Land along the western, southern, and northwestern portions of the city, with large areas of “Other Land” interspersed throughout the eastern and central portions. The proposed improvements would be contained in urbanized landscapes and public rights-of-way and would not have a substantial adverse effect on the remaining agricultural areas within the city. No substantial new information has been presented that shows the Projects would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? One small Williamson Act contract area is located within Carlsbad, east of Interstate 5 at Palomar Airport Road (City 2015a). This property would be unaffected by the Projects and therefore the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code Section 4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))? As described in Section 5.1 of the PEIR, the city’s service area does not include any forest land or timberland zoned for timberland production. This circumstance remains unchanged, and no new or more substantial impacts would result under the proposed Projects. d) Result in the loss of forest land or conversion of forest land to non-forest use? As described under c), the Projects would result in no impacts to forest land or timberland production. e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use? As described under a) and c), the proposed Projects would result in no impacts to agricultural resources, forest land, or timberland production. El Fuerte/Maerkle Motorized Valves Project 12 III. Air Quality Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? Yes No No No b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non- attainment under an applicable federal or state ambient air quality standard? Yes No No No c) Expose sensitive receptors to substantial pollutant concentrations? Yes No No No d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? Yes No No No a) Conflict with or obstruct implementation of the applicable air quality plan? Section 4.2 of the PEIR determined that the Master Plans would not conflict with or obstruct implementation of the Regional Air Quality Strategy or State Implementation Plan and a less than significant impact would occur. The existing regulatory framework governing air quality planning in the city has not substantially changed since the certification of the PEIR. The San Diego Air Basin continues to be in attainment for carbon monoxide (CO), nitrogen dioxide (NO2), lead, and sulfur dioxide (SO2), attainment/unclassifiable for (PM2.5) and (PM10), and non-attainment for ozone (8-hour) with respect to federal air quality standards. With respect to state air quality standards, the San Diego Air Basin continues to be in attainment for CO, NO2, lead, SO2, and non-attainment for ozone, PM2.5 and PM10. The Projects would not result in population growth that would exceed the population projections accounted for in the Regional Air Quality Strategy and State Implementation Plan. Furthermore, the construction and operational characteristics as described in Section 4.2 have not substantially changed since the certification of the PEIR. No substantial new information has been presented that shows more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new significant impacts. The conclusion of less than significant, as identified in the PEIR, remains accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 13 As provided in Section 4.2 of the PEIR, construction of the CIP projects proposed under the Master Plans would result in temporary increases in air pollutant emissions. While excavation was not proposed for the Maerkle valve site, excavation as a construction activity was analyzed and included in the PEIR. Impacts related to the site would be consistent with those presented in the PEIR and 2019 Addendum. These emissions would be generated in the form of fugitive dust emissions (PM10 and PM2.5) and ozone precursor emissions (NOx, volatile organic compounds). Operation of heavy equipment and vehicles during the construction phases would generate exhaust emissions from fuel combustion. Fugitive dust emissions would be generated from earth disturbance during site grading and structure demolition, as well as from construction vehicles operating on vacant areas or dirt roadways within or adjacent to CIP construction sites. The city has committed to implementing best management practices (BMPs), identified as project design features in the MMRP, to reduce fugitive dust emissions and other criteria pollutant emissions during construction of CIP projects. The PEIR contemplated the construction of the Master Plan(s) CIP projects would take place over an approximately 23 year period between 2012 and 2035. The PEIR estimated the construction emissions for the overall Master Plan Updates using conservative assumptions, which considered simultaneous construction of multiple projects covered under the Master Plans. The construction parameters as described for the Project would be contained within the conservative scenario described in Section 4.2.3.2 of the PEIR. Based on the fact that emissions calculated at the programmatic level for the Master Plans were determined to be less than significant, it is reasonable to conclude that construction emissions for the proposed Projects would not exceed San Diego Air Pollution Control District’s significance thresholds and therefore would be less than significant. For this reason, no substantial new information has been presented that shows more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non- attainment under an applicable federal or state ambient air quality standard? The potential impacts associated with a cumulatively considerable net increase of criteria pollutants were analyzed in the PEIR (Section 4.2) and 2019 Addendum. The city has committed to implementing BMPs, identified as project design features in the MMRP, to reduce fugitive dust emissions and other criteria pollutant emissions during construction of the Projects. With the implementation of BMPs contained in the MMRP, the PEIR determined that the Master Plans would result in a less than significant impact. Further, the Projects would be improvements to existing valve facilities that would not result in new sources of operational criteria pollutants. During facility operation, occasional vehicle trips may be required for repair or inspection and periodic maintenance. The PEIR and 2019 Addendum determined operational air pollutant emission impacts associated with the proposed CIP projects would be less than significant. The existing air quality conditions, including the local air basins attainment status, have not substantially changed since the certification of the PEIR. Furthermore, the construction and operational activities of the Projects have not changed substantially from those certified in the PEIR. No substantial new information has been presented that shows more significant impacts would result under the proposed Projects than those originally analyzed in the PEIR or 2019 Addendum and there would be no new El Fuerte/Maerkle Motorized Valves Project 14 significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Expose sensitive receptors to substantial pollutant concentrations? The potential impacts associated with exposure of sensitive receptors to pollutant concentrations were analyzed in the PEIR (Section 4.2) and 2019 Addendum. The PEIR determined that the CIP projects covered under the Master Plans would not expose sensitive receptors to substantial pollutant concentrations and a less than significant impact would occur. The potential for substantial pollutant generation due to construction of the Projects has not changed since the certification of the PEIR. Once installed, the Project components would not generate substantial pollutant concentrations. The construction and operational characteristics of the Projects have not changed substantially compared to the activities included in the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? The potential impacts associated with odors were analyzed in the PEIR (Section 4.2) and 2019 Addendum. The PEIR determined that the Master Plans would not create objectionable odors and a less than significant impact would occur. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. The proposed Project valve improvements, once installed, would not result in emissions such as odors. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 15 IV. Biological Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? Yes No No No b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Wildlife or US Fish and Wildlife Service? Yes No No No c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Yes No No No d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Yes No No No e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Yes No No No f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? Yes No No No The discussion below is based in part on a biological survey prepared by HELIX Environmental Planning, Inc. (HELIX 2022a) for the Maerkle valve site, attached to this Addendum as Appendix A. El Fuerte/Maerkle Motorized Valves Project 16 a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? Section 4.3, Biological Resources, of the PEIR provides a programmatic evaluation of potential impacts, either directly or through habitat modifications, on plant and wildlife species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service. Appendix B of the PEIR includes a tabular listing of the special status species considered in 2012. An updated species list was requested from the U.S. Fish and Wildlife Service in 2019 to confirm current listings and was included in Appendix B of the 2019 Addendum. Tables 4.3-3 and 4.3-4 in the PEIR identify projects that would occur within Carlsbad and be subject to the conditions of Carlsbad’s Habitat Management Plan (HMP) and associated species avoidance, minimization, and compensatory mitigation requirements. The Carlsbad HMP was in part developed to set aside land in preservation to use as mitigation for future projects. Based on the programmatic evaluation, the special status species with potential to be impacted by CIP projects within Carlsbad are all likely to be covered species or narrow endemic species under the Carlsbad HMP. Species not covered under the Carlsbad HMP are not likely to occur within the CIP project sites. Therefore, species not covered under the Carlsbad HMP are not likely to be adversely affected by CIP projects. Project-level surveys and/or avoidance and minimization measures were proposed for the CIP projects listed in Table 4.3-3 to ensure that the appropriate measures are implemented to address special status species with the potential to occur, including projects that are not covered under the Carlsbad HMP per HMP Appendix B. None of the Projects were identified as requiring surveys or minimization measures. However, due to the change in activities proposed at the Maerkle valve site, a project-specific survey was completed in accordance with Mitigation Measure Bio-1A. Surveys were not conducted for the specific corrosion test station sites as construction activities would occur within existing developed roadways where no sensitive biological resources are present. Direct impacts include the direct take, removal, or displacement of special status species and their habitat through activities such as clearing, grubbing, grading, and other land disturbance activities. Removal of habitat could result in displacement of special status wildlife and less habitat available within a species’ range to carry out vital life history requirements such as breeding, foraging, dispersal, migration, aestivation (i.e., underground dormancy or torpor during the summer) and predator evasion. Construction activities could also result in the removal or trimming of trees and shrubs during the general bird nesting season (January 15 through September 15). Indirect impacts could also result in temporary increases in noise levels, which could adversely affect special status wildlife species occupying adjacent habitats, including nest failure. Impacts to special status species were identified as less than significant with mitigation in the PEIR. Implementation of Mitigation Measures Bio-1D through Bio-1I and Bio-2A at the Maerkle valve site would reduce direct and indirect impacts on special species and their habitat to a less than significant level. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 17 b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? As evaluated in Section 4.3 of the PEIR, construction of CIP projects has the potential to result in direct impacts to riparian habitat and several types of sensitive natural communities. Habitat loss or disturbance as a consequence of these CIP project construction activities could result in diminishing and degrading of open space areas, reductions, or eliminations of habitat functions and values, and impacts to species, among other adverse impacts. These direct impacts were identified as a significant in the PEIR prior to the implementation of mitigation. Impacts to sensitive vegetation communities at the Maerkle valve site are anticipated to total 0.08 acre. Mitigation would be provided in accordance with the ratios provided in Mitigation Measure Bio-2A at the Lake Calavera Mitigation Bank and would total 0.04 acre of mitigation for impacts to 0.04 acre of coastal sage scrub and 0.04 acre of disturbed habitat (mitigation rounded to the nearest 0.01 acre) (HELIX 2022a). Implementation of Mitigation Measure Bio-2A in would reduce direct impacts on sensitive habitats to a less than significant level. The regulatory requirements have not substantially changed since the certification of the PEIR. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? As evaluated in the programmatic analysis provided in Section 4.3 of the PEIR, the construction of the CIP projects would have the potential to result in direct impacts to riparian and wetland habitat types that could support jurisdictional waters and wetlands. Activities associated with construction of specific CIP projects (see Table 4.3-7 of the PEIR) could be subject to the regulatory jurisdiction of the U.S. Army Corps of Engineers (USACE), Regional Water Quality Control Board (RWQCB), and/or California Department of Fish and Wildlife (CDFW). However, none of the proposed Project sites occur within or adjacent to jurisdictional wetlands. The city is required to prepare and implement BMPs to minimize, control, and treat storm water runoff, fugitive dust, and other pollutants at the CIP construction site. Implementation of these required practices would reduce potential indirect impacts during construction to a less than significant level. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 18 d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? As provided in Section 4.3 of the PEIR, the proposed CIP projects are proposed within disturbed and developed land that contains existing development and none of the proposed projects are anticipated to adversely affect, either directly or indirectly, the continued function of wildlife movement. The proposed Projects’ footprints would be limited in overall space, and confined, such that wildlife could continue to move through the local area and around the proposed developments. Due to the small size and limited above-ground features proposed as part of the Projects, no adverse effects toward wildlife movement are anticipated to occur. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? The city and CMWD are required to comply with the Carlsbad HMP and provisions of the Carlsbad Local Coastal Plan, including the Coastal Resource Protection Overlay Zone Ordinance; however, the proposed Projects are not within the Coastal Zone and implementation of the proposed Master Plans were determined not to conflict with the adopted Coastal Resource Protection Overlay Zone Ordinance. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? As evaluated above, the Projects could result in potential impacts to sensitive species and habitat that are addressed within the Carlsbad HMP. Based on the potential for impacts to sensitive species at the Maerkle valve site, a minor HMP Permit from the city would be required to approve and implement the Projects in accordance with Carlsbad Municipal Code Chapter 21.210. The Maerkle valve improvement is consistent with the Carlsbad HMP because it has been sited within existing disturbed and developed land that is subject to regular maintenance, and would only impact a very small (less than 0.1 acre) area of previously restored Diegan coastal sage scrub. Mitigation would be provided for direct and indirect impacts consistent with the Carlsbad HMP and PEIR, as discussed above. No substantial new information has been presented that shows more significant impacts would result under the Projects than those originally analyzed in the PEIR and there would be no new significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 19 V. Cultural Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Cause a substantial adverse change in the significance of a historical resource pursuant to §15064.5? Yes No No No b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? Yes No No No c) Disturb any human remains, including those interred outside of dedicated cemeteries? Yes No No No The discussion below is based on a cultural report prepared by HELIX Environmental Planning, Inc. for the Maerkle site, attached to this Addendum as Appendix B (HELIX 2022b). a) Cause a substantial adverse change in the significance of a historical resource pursuant to §15064.5? Section 4.4, Cultural and Paleontological Resources, of the PEIR provides a programmatic assessment of the potential impacts to historic resources based on the CIP projects outlined in the 2012 Master Plans. The PEIR notes various existing built-environment historical resources (buildings or structures aged 45 years old or older) and numerous archaeological sites within its study area. The PEIR included a cultural resources records search to evaluate the presence of known historical and archaeological resources for areas potentially impacted by the Master Plans. One sewer project included in the 2019 Addendum would be located in proximity to a historical resource; however, the project would not result in the disturbance or alteration of the historical resource. The PEIR and 2019 Addendum concluded that the Master Plan Updates would result in less than significant impacts to historical resources. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? Section 4.4 of the PEIR provides an assessment of potential impacts of the Master Plan improvements to known and undocumented archaeological resources. Known cultural resources that may be affected by the construction of proposed CIP project sites are listed by Master Plan improvements in Tables 4.4-3 to El Fuerte/Maerkle Motorized Valves Project 20 4.4-5 of the PEIR. Additionally, the PEIR notes a high archaeological resource sensitivity for its entire study area. The El Fuerte (21) and Maerkle (R7) sites were identified as sites within previously disturbed setting such that archaeological resources would have been removed or destroyed by previous construction. A table that identifies which CIP projects would have the potential to impact each resource is available in Confidential Appendix D2. This appendix is available to qualified viewers at the City of Carlsbad, 1635 Faraday Avenue, Carlsbad, CA 92008. These resources are predominately prehistoric archaeological sites of varying sizes and occupancy duration and exhibit prehistoric material culture through midden and scatters of lithic and groundstone tools. In addition, some of the identified sites in Tables 4.4-3 to 4.4-5 are considered historical resources pursuant to CEQA because they retain the potential to yield data important to prehistory or history (Criterion 4 of the California Register of Historic Resources). The PEIR concluded that the Master Plan improvements could result in a potentially significant impact to archaeological resources in the absence of mitigation. With the incorporation of Mitigation Measure Cul-1, this impact would be reduced to a level of less than significant. A Project-specific cultural resources report was prepared in accordance with Mitigation Measure Cul-1 for the Maerkle valve site due to the proposed excavation activity. The El Fuerte site was previously determined in the PEIR and 2019 Addendum to not require mitigation related to cultural resources due to its disturbed location. The additional corrosion testing sites would also be located within the existing roadway and sidewalks, which have previously been disturbed. The records search for the Maerkle valve site resulted in the identification of ten cultural resources within the records search limits, all of which are located a quarter-mile or more from the report’s Study Area. In general, the resources included shell scatters, artifact scatters, milling areas, and the historic Rancho de los Quiotes to Mission San Luis Rey trail. The Native American Heritage Commission (NAHC) search of their Sacred Land Files indicated that tribal cultural resources may be present and noted to contact the La Jolla Band of Luiseno Indians and the San Luis Rey Band of Mission Indians for additional information regarding the resources. CMWD met with representatives from the San Luis Rey Band and discussed the Maerkle site conditions and proposed activities. The San Luis Rey Band requested that spot-check monitoring occur for Maerkle valve site due to the cultural sensitivity of the project region. No response from the La Jolla Band was received in response to CMWD outreach. The review of aerial imagery undertaken as part of the project-level cultural resources review indicates that the entirety of the Maerkle valve project area, as well as the area surrounding it, was rough graded in 1990 for the upgrade and expansion of the Maerkle Reservoir, which included an installation of a buried tank that is situated directly north of the project area. Additionally, the review of geologic and soil conditions for the project area do not indicate the presence of young alluvium soils within the Study Area, which typically contain a higher potential for buried cultural resources to be present. As such, it is likely the case that the grading that occurred in 1990 removed any potential for cultural resources to still be present within the project area. Per Cul-1 (2) in the PEIR MMRP, for those CIP project site(s) not addressed by a current cultural resources report (produced within five years of project proposal), a project-level Phase I Cultural Resources Survey shall be prepared in accordance with the 2017 Guidelines. While the cultural resources survey that encompassed the Study Area was conducted over 30 years ago, the Study Area is within a previously disturbed area and is not in close proximity to a known cultural resource. Therefore, no further cultural resources work, including a project-level Phase I cultural resources survey, was recommended for activity at the Maerkle valve site. However, while a project-level Phase I survey is not necessary for the Maerkle valve project area, cultural resources monitoring will occur for the Maerkle valve site, based on the concerns and recommendations provided by the San Luis Rey Band of Mission Indians. During vault excavation, spot check monitoring would be El Fuerte/Maerkle Motorized Valves Project 21 required. Full-time monitoring would not be required for vault excavation and no monitoring would be required for Maerkle valve replacements. Since the certification of the PEIR, the city adopted the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017), which updated and replaced the city’s 1990 Cultural Resource Guidelines. The 2017 guidelines are incorporated by reference into the 2019 Addendum MMRP to reflect the city’s established standards of performance for cultural resources investigations following the city’s General Plan Update (2015a), the adoption of Assembly Bill 52 in 2014, and the corresponding amendments to Appendix G of the CEQA Guidelines (as amended). With the incorporation by reference of the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017), the Projects would have a less than significant impact. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR or 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Disturb any human remains, including those interred outside of dedicated cemeteries? Section 4.4 of the PEIR documents the presence of formal cemeteries within the CMWD service area; however, the section explains that none of the CIP projects are proposed within their boundaries. Therefore, it is not expected that construction activities at CIP sites would disturb formal cemeteries. Sections 15064.5(d) and (e) of the CEQA Guidelines assign special importance to human remains and specifies procedures to be used when Native American remains are discovered. As provided in the PEIR, these procedures are detailed under Public Resources Code (PRC) Section 5097.98. The disturbance of any human remains is considered a significant impact, regardless of archaeological significance or association. Any ground disturbing activities, including grading, trenching, and excavation during construction of the Projects, would have the potential to unintentionally disturb human remains, resulting in a significant impact. Implementation of the required protocol in accordance with PRC Section 5097.98 and California State Health and Safety Code Section 7050.5, to be followed upon unintentional disturbance of human remains, would minimize potential impacts on human remains to a level of less than significant. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR or 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 22 VI. Energy Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? Yes No No No b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? Yes No No No a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? Section 4.5, Energy, of the PEIR provides an assessment of the Master Plans effects on existing water, sanitary sewer, and recycled water facilities energy use. The PEIR concluded that the Master Plans would not generate a substantial net increase in vehicle trips based on pre-existing maintenance activities. The proposed valve replacements and corrosion testing stations at existing facilities would not result in an increase in energy demand at these facilities compared to existing conditions. The PEIR includes standard BMPs, identified as project design features in the adopted MMRP, to minimize energy consumption during construction: • Electrical power will be supplied from commercial power supply wherever feasible, to avoid or minimize the use of engine-driven generators; and • Trucks and equipment will not idle for more than 15 minutes when not in service. The city and CMWD conduct routine maintenance on all infrastructure facilities and would incorporate the proposed Projects into the maintenance schedule. The PEIR noted a potential total net increase in electricity demand of 3.96 kilowatt hour (kWh) at buildout of the sewer, water, and recycled water systems, which was approximately double existing electricity demand in 2012. Total energy use as it relates to water, sanitary sewer, and recycled water is largely a function of the city’s water demands, which in 2012 was projected to be 20.8 mgd (23,296 afy) in 2035 and increased to 21.4 mgd (23,968 afy) at buildout. The 2019 Addendum stated that based on updates to the city’s growth, the updated projected potable water demand at buildout is 18.5 mgd (20,720 afy), comparatively lower than the previous predictions. Therefore, the projected energy demands under the Projects, as provided in the 2019 Addendum, would be less than analyzed in 2012 and the impact would be less than significant. El Fuerte/Maerkle Motorized Valves Project 23 No substantial new information has been presented that shows more significant impacts would result under the Projects than those originally analyzed in the PEIR or 2019 Addendum and there would be no new significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? As provided in a), the CIP projects described in the 2019 Addendum would result in a lower water demand than considered in the PEIR. In addition, these projected estimates are consistent with the city’s General Plan Update (2015a) and policies related to energy efficiency. For these reasons, the Projects would not conflict with plans or policies adopted for the purposes of promoting energy efficiency, and the impact is less than significant. VII. Geology and Soils Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving: i.

Yes No No No c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? Yes No No No El Fuerte/Maerkle Motorized Valves Project 24 Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? Yes No No No e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? Yes No No No f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Yes No No No a) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving: i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42? The potential impacts associated with exposure of people or structures to potential substantial adverse effects involving rupture of an earthquake fault were analyzed in the PEIR (Section 4.6, Geology and Soils) and 2019 Addendum. The PEIR determined that surface rupture as a result of seismic activity is unlikely throughout the CMWD service area and no impact would occur. ii. Strong seismic ground shaking? The potential impacts associated with exposure of people or structures to potential substantial adverse effects involving strong seismic shaking were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would not exacerbate existing hazards related to strong seismic shaking. The proposed Projects would be required to comply with the city’s engineering standards and standard engineering practices. As a result, this impact would be less than significant. iii. Seismic-related ground failure, including liquefaction? The potential impacts associated with exposure of people or structures to potential substantial adverse effects involving seismic-related ground failure were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would result in a less than significant impact and would not exacerbate existing hazards related to seismic-related ground failure. The Projects would be required to comply with the city’s standards and standard engineering practices. El Fuerte/Maerkle Motorized Valves Project 25 iv. Landslides? The potential impacts associated with exposure of people or structures to potential substantial adverse effects involving landslides were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would result in a less than significant impact associated with landslides. Individual projects would be required to comply with the city’s engineering standards and grading requirements, which would minimize any hazards related to cut and fill slopes and related landslide hazards. These requirements would minimize any impacts to less than significant levels. In summary, the improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. For these reasons, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Result in substantial soil erosion or the loss of topsoil? The potential impacts associated with soil erosion were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would result in a less than significant impact associated with soil erosion. The Projects’ construction activities would be regulated under the NPDES General Permit for Discharges of Storm Water Runoff Associated with Construction Activity (General Construction Permit, NPDES Order No. 2012-0006-DWQ). In addition, the city would comply with applicable grading ordinance(s) and/or erosion control requirements. Compliance with existing regulations would minimize the potential for erosion during construction such that the impact is considered less than significant. The physical improvements proposed as part of the Projects have not substantially changed from the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. For these reasons, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? As described in a), the PEIR considered geologic hazards as it relates to the proposed Master Plan improvements and determined that a less than significant impact would result as it relates to hazards from unstable geologic units or soils. Projects would be required to comply with city standards and standard engineering practices. Compliance with existing state and local regulations would minimize potential impacts to less than significant. The physical geologic and soil conditions in the areas of the Projects have not substantially changed since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. For these reasons, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 26 d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? The potential impacts associated with expansive soils were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would result in a less than significant impact associated with expansive soils. Projects would be required to comply with the city’s standards and standard engineering practices. The physical improvements proposed for the Projects have not substantially changed since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? The potential impacts associated with septic tanks or alternative wastewater disposal systems were analyzed in the PEIR (Section 4.6) and 2019 Addendum. Similar to the adopted Master Plans and 2019 Addendum, alternative wastewater disposal systems and septic tanks are not a component of the proposed Projects and, therefore, no impact would result. f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Section 4.4, Cultural and Paleontological Resources, of the PEIR provided an analysis of the potential impacts of the Master Plan improvements to paleontological resources. Excavation and construction activities associated with proposed CIP projects have the potential to disturb or destroy paleontological resources depending on their location within the context of geologic formations with moderate and high paleontological sensitivity. Figure 4 and Table 1 of the city’s adopted 2017 Guidelines identify the moderate and high paleontological sensitive geologic formations within the city. The Point Loma formation, Santiago formation, and Bay Point formation are identified as high paleontological sensitivity, and the Lusardi, Delmar, late to middle Pleistocene, late Holocene marine beach, and late Holocene paralic estuarine deposits are identified as moderate sensitivity. Implementation of Mitigation Measure Pal-1 would minimize potential impacts associated with the disturbance of paleontological resources. Pal-1 was not identified in the 2019 Addendum as applicable to any of the proposed Project sites (W-9, W-13, or 50071). The Maerkle valve site (W-9) is located within a low sensitivity area according to Figure 4 of the city’s 2017 Guidelines. The additional corrosion testing site components (50071) proposed at the El Fuerte valve site (W-13) would be within the area previously trenched for the installation of the existing pipe and would not result in a disturbance to paleontological resources. Therefore, implementation of Pal-1 would not be required and impacts associated with the disturbance of paleontological resources would be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 27 VIII. Greenhouse Gas Emissions Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Yes No No No b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? Yes No No No a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Section 4.7, Greenhouse Gas Emissions, of the PEIR provides an analysis of the potential for the Master Plan improvements to result in the generation of GHG emissions. Since the preparation of the PEIR, the city adopted a CAP (September 2015) that outlines actions the city will undertake to achieve its proportional share of GHG reductions. The CAP identified project screening thresholds based on guidance from the California Air Pollution Control Officers Association. The city determined that new development projects emitting less than 900 metric tons (MT) carbon dioxide equivalent (CO2e) annual GHG would not contribute considerably to cumulative climate change impacts (City 2015b). If a proposed project exceeds the CAP’s 900 MT CO2e screening threshold, the project proponent must complete the CAP Consistency Checklist to demonstrate consistency with the CAP, or a self-developed GHG-reduction program. The city analyzed the Master Plan Updates proposed in the 2019 Addendum for GHG impacts using the CAP’s screening threshold of 900 MT of CO2e per year (City 2015b). Construction of the Projects would result in temporary emissions of GHG from the operation of construction equipment and from worker and building supply vendor vehicles. Equipment that is associated with construction activity includes dozers, rollers, dewatering pumps, backhoes, loaders, delivery, and haul trucks. The PEIR determined that the most conservative construction scenario, where all projects would be constructed simultaneously and completed in seven months, would result in GHG emissions of 959 MT CO2e. The 2012 Master Plan included the construction of 50 separate projects while the 2019 Master Plan Updates included the construction of 27 separate projects. Therefore, the GHG emissions of 959 MT CO2e included in the PEIR and 2019 Addendum is conservative for the construction of the proposed Projects. Projected electrical demand in the PEIR was based on projected water demand, which was updated in the 2019 Addendum based on updates to the city’s growth. The updated projected potable water demand at buildout is 18.5 mgd (20,720 afy), which would reduce the increased electrical demand to El Fuerte/Maerkle Motorized Valves Project 28 1.0 million kWh. Using a carbon intensity factor of 630 pounds of CO2e per megawatt hour, the operational GHG associated with the 2019 Master Plan Updates was projected to be 257 MT CO2e per year. The total annual GHG emissions from construction and operation of the 2019 Master Plan Updates was estimated at 289 MT CO2e. This is below the 900 MT of CO2e per year screening threshold established by the city. No components of the proposed Projects would substantially change construction or operational GHG emissions that were assumed for the Projects under the 2019 Addendum. The new valves would replace existing components and consume similar amounts of energy. For this reason, the impact would be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases? The city’s CAP is considered a qualified GHG reduction plan in accordance with CEQA Guidelines Section 15183.5. The Projects would be consistent with Measure N of the city’s CAP: Reduce GHG Intensity of Water Utilities Supply Conveyance, Treatment, and Distribution. The Projects would result in GHG emission reductions from changes in the efficiency of water utilities (including water supply, wastewater, and recycled water) conveyance, treatment, and distribution facilities within the city. The City Council adopted Policy 71: Energy Conservation and Management, in July 2006. This Policy outlines measures to help Carlsbad reach the goals set out by the city’s Energy Conservation and Management Program, including reducing demand on the energy grid. The Projects would assist the city to reduce demand on the energy grid from the changes in the efficiency of water utilities conveyance, treatment, and distribution facilities within the city. As provided in a) and in this response, the Projects are consistent with the CAP because they would not exceed the 900 MT of CO2e per year screening threshold established by the city and would result in GHG emission reductions. This response also demonstrates consistency with City Council Policy 71 due to changes in efficiency of water utilities. El Fuerte/Maerkle Motorized Valves Project 29 IX. Hazards and Hazardous Materials Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Yes No No No b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Yes No No No c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Yes No No No d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? Yes No No No e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area? Yes No No No f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Yes No No No g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires? Yes No No No El Fuerte/Maerkle Motorized Valves Project 30 a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? The PEIR (Section 4.8, Hazards and Hazardous Materials) and 2019 Addendum provided assessments of the potential for the routine use, transport, or disposal of hazardous materials. As provided, there are multiple federal, state, and local laws and regulations, such as Resource Conservation and Recovery Act, Title 22 of the California Code of Regulations, the Hazardous Waste Control Law, Hazardous Materials Transportation Act, and Hazardous Material Business Plans, that the Projects are required to comply with by law. Therefore, impacts associated with the use, transport, and disposal of hazardous materials generated from construction and operational activities were determined to be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? The PEIR (Section 4.8) and 2019 Addendum provided assessments of the potential for the accidental release of documented and undocumented sources of hazardous materials. As provided in the PEIR, the city has committed to the BMPs listed as project design features in the MMRP for hazardous materials. These included a site-specific hazardous materials record search for the locations and type of hazardous materials for each CIP project and, if required, a site assessment. Conducting a hazardous materials database search and environmental site assessment prior to any ground-disturbing activities associated with the construction of CIP sites would identify hazardous materials that could be encountered during CIP construction activities. With these precautions, the impact was concluded to be less than significant. The Project sites were searched for hazardous material sites on the databases maintained by the State Water Resources Control Board (SWRCB) and California Department of Toxic Substances Control (DTSC). No hazardous materials sites were identified in the vicinity of the Project sites, and therefore impacts related to potential hazardous materials would be less than significant (SWRCB 2022; DTSC 2022). The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? The PEIR (Section 4.8) and 2019 Addendum provided assessments of the CIP projects and potential for the emission of hazardous materials within a quarter mile of a school. As provided, the activities and CIP components would be operated in compliance with applicable regulations that would minimize foreseeable risks of an accident that could create a hazard to the public or environment. Therefore, El Fuerte/Maerkle Motorized Valves Project 31 implementation of the Projects would not result in hazardous emissions within one-quarter mile of an existing or proposed school and impacts would be less than significant. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? The potential impacts associated with the disturbance of listed hazardous materials sites were analyzed in the PEIR (Section 4.8) and 2019 Addendum. As discussed in response b), the specific sites of the Projects were searched for hazardous materials sites compiled pursuant to Government Code 65962.5 and no potential hazards related to the Projects were identified. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area? The potential impacts associated with airport safety hazards were analyzed in the PEIR (Section 4.8) and 2019 Addendum. The PEIR and 2019 Addendum determined that no impact would occur. No substantial new information has been presented that shows the Projects would result in substantially more severe impacts than those originally analyzed in the PEIR or 2019 Addendum. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? The PEIR (Section 4.8) and 2019 Addendum evaluated issues related to emergency response and evacuation. The PEIR noted that construction activities associated with the Master Plans, particularly excavation and trenching activities associated with pipeline extensions or other improvements that are within roadway rights-of-way, may result in temporary, construction-related lane and road closures or detours. As provided in the PEIR, the city has committed to preparing a traffic control plan for applicable CIP projects and coordinating with the cities of Oceanside, Vista, and San Marcos. With implementation of a traffic control plan for construction activities within roadways, the Projects would result in less than significant impacts on emergency response or evacuation plans. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 32 g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires? The PEIR (Section 4.8) and 2019 Addendum included analysis of wildfire hazards. As provided, CMWD service area includes mostly urbanized areas; however, portions of the city service area are located in areas classified as Very High Fire Hazard Severity Zones; particularly in the eastern area of the service area (California Department of Forestry and Fire Protection [CAL FIRE] 2009). Only the Maerkle valve site of the Project is located within a Very High Fire Hazard Severity Zone. As provided in the PEIR, construction and design of all CIP projects would comply with the Uniform Fire Code (Title 24 Code of Federal Regulations, Part 9), which requires installation of sprinkler systems, fire- resistant building materials, standard roadway access widths, and other features to ensure that all above-ground structures are constructed with all reasonable fire safety features. Additionally, the city has committed to the multiple design features to minimize impacts related to wildfire: • Fire safety information will be disseminated to construction crews during regular safety meetings. Fire management techniques will be applied during project construction as deemed necessary by the lead agency and depending on-site vegetation and vegetation of surrounding areas. • A brush management plan will be incorporated during project construction by the city, CMWD, or a contractor, as necessary. Construction within areas of dense foliage during dry conditions will be avoided, when feasible. • In cases where avoidance is not feasible, necessary brush fire prevention and management practices will be incorporated. Specifics of the brush management program will be determined as site plans for the project are finalized. Preparation of a brush management plan and dissemination of fire safety information to construction crews would minimize hazards to a level of less than significant. As such, the Projects would not expose people or structures to a significant risk of loss, injury, or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 33 X. Hydrology and Water Quality Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? Yes No No No b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? Yes No No No c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: i. Result in substantial erosion or siltation on- or off-site? Yes No No No ii. Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off- site? Yes No No No iii. Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional resources of polluted runoff? Yes No No No iv. Impede or redirect flood flows? Yes No No No d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? Yes No No No e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? Yes No No No El Fuerte/Maerkle Motorized Valves Project 34 a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? The PEIR (Section 4.9, Hydrology and Water Quality) and 2019 Addendum provide assessments of the potential for impacts associated with the Master Plan improvements to result in a violation of water quality standards or waste discharge requirements. During construction, there is potential for sediment and other construction-related contaminants to enter waterways from runoff. The PEIR determined that the Master Plans would result in a less than significant water quality impact based on the pre-existing NPDES and local grading and erosion ordinance requirements. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? The potential impacts associated with depletion of groundwater supplies were analyzed in the PEIR (Section 4.9) and 2019 Addendum. Construction activities associated with the Master Plans may require temporary dewatering. The proposed Projects would not involve any groundwater extraction. The PEIR determined that the Master Plans would result in a less than significant impact associated with depletion of groundwater supplies. This circumstance remains unchanged under the Projects based on the overall reduction in water demands. The construction and operational characteristics of the Projects have not substantially changed since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: The potential for impacts associated with the CIP improvements to result in alteration of existing drainage patterns and flood hazards were analyzed in the PEIR (Section 4.9) and 2019 Addendum. The proposed improvements at the Maerkle valve site may involve excavation/grading, vegetation trimming or removal activities, and could result in temporary changes to existing drainage patterns during construction. The PEIR determined that the Master Plan improvements would result in less than significant impacts to existing drainage patterns and flood hazards with conformance to existing NPDES and local grading and erosion control requirements. El Fuerte/Maerkle Motorized Valves Project 35 i. Result in substantial erosion or siltation on- or off-site? As provided in a), the improvements covered under the Projects would be subject to NPDES and local grading and erosion control requirements. As a result, the Projects would not result in substantial erosion or siltation on- or off-site. ii. Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off- site? As noted above, the Projects would be subject to NPDES and local grading and erosion control requirements. As a result, the Projects would not substantially increase the rate or amount of surface runoff in a manner which would result in flooding on-or off-site. iii. Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional resources of polluted runoff? The Projects would result in minor additions to impervious surfaces; however, these additions would not be of a scale that could create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. iv. Impede or redirect flood flows? No changes in channel structures are proposed that could impede or redirect flood flows. Alterations to impervious surfaces would not be of an extent that could impede or redirect flood flows. d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? The potential impacts associated with inundation by seiche, tsunami, or mudflow were analyzed in the PEIR (Section 4.9) and 2019 Addendum. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? See responses to a) and b). As provided, the Projects would result in less than significant impacts El Fuerte/Maerkle Motorized Valves Project 36 XI. Land Use and Planning Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Physically divide an established community? Yes No No No b) Cause significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? Yes No No No a) Physically divide an established community? Section 4.10, Land Use and Planning, of the PEIR provides an assessment of the Master Plan’s potential to result in the division of established communities. The PEIR and 2019 Addendum determined that the CIP projects, including the Projects as initially proposed, would not divide an established community. The Projects would be constructed on existing public road rights-of-way, a small easement, and existing city facilities. These land use conditions remain unchanged with the proposed Projects. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Cause significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? As discussed in Section 4.10 of the PEIR, the Master Plans’ CIPs are designed to provide Carlsbad with plans for the development of water utilities to meet the present and future needs of the projected growth and land uses within each service area. Implementation of the Master Plans would not induce any unplanned growth that would be inconsistent with the city’s General Plan, which was formally updated in 2015, or its Growth Management Plan. Future projects would be required to comply with all applicable land use regulations in order to obtain project approval and would be further evaluated at the time of project design and review. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 37 XII. Mineral Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? Yes No No No b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan? Yes No No No a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? Section 5.1, Effects Found Not Significant, of the PEIR includes the topic of Mineral Resources. As provided, impacts to mineral resources were determined to have no impact because the improvements were driven by new growth and ongoing condition assessment of existing infrastructure. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan? See response a). No impact would result from the Projects. El Fuerte/Maerkle Motorized Valves Project 38 XIII. Noise Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project result in: a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Yes Yes Yes No b) Generation of excessive groundborne vibration or groundborne noise levels? Yes Yes Yes No c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Yes Yes Yes No a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Section 4.11, Noise, of the PEIR provides an assessment of the potential impacts to noise sensitive land uses resulting from the construction and long-term operation of the Master Plan improvements. As noted in the PEIR and 2019 Addendum, maintenance trips would be spread across all facilities, including the Projects, and would not be concentrated on a specific roadway. Due to the minimal number and geographic distribution of vehicular trips associated with the maintenance of the CIP projects overall, transportation noise increases would be negligible. Under the Projects, these circumstances would remain unchanged and would result in less than significant permanent increases in ambient noise associated with transportation noise sources. The city has committed to ensuring that operating equipment will be designed to comply with all applicable local, state, and federal regulations. The Projects would not generate operational noise once installed and would not result in a substantial increase in ambient noise levels. According to the PEIR and 2019 Addendum, construction of the CIP projects would result in temporary increases in ambient noise levels. Construction activities associated with the Projects would involve the use of heavy equipment during vegetation clearing, trenching, and installation of equipment, such as valves and corrosion test station equipment. The magnitude of the impact would depend on the type of El Fuerte/Maerkle Motorized Valves Project 39 construction activity, type of construction equipment, duration of the construction phase, distance between the noise source and receiver, and any intervening topography. As provided, sound levels of typical construction equipment range from 60 decibels to 90 decibels at 50 feet from the source (U.S. Department of Transportation 2008). The PEIR included construction BMPs, identified as project design features in the MMRP, to minimize noise effects to surrounding neighborhoods. These measures are included in the city’s MMRP. The construction activities proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Generation of excessive groundborne vibration or groundborne noise levels? The PEIR (Section 4.11, Noise) and 2019 Addendum provide assessments of the potential vibration impacts to sensitive land uses resulting from the construction and long-term operation of the CIP improvements. Vibration sources associated with implementation of the Projects would be generated primarily from construction. Once installed, the Projects would include passive uses that do not generate substantial levels of vibration. As provided in the PEIR, construction-related vibration would have the potential to impact nearby structures and vibration-sensitive equipment and operations. The level of vibration generated from construction activities would depend on multiple factors including soil type, distance, and the energy- generating capability of the construction equipment. The PEIR’s MMRP included measures for construction to minimize vibration effects to surrounding neighborhoods. The construction activities proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? The Projects would be located within the McClellan-Palomar Airport Influence Area but are not in the identified airport noise contours. The Projects’ improvements do not involve any features for human occupancy that would result in regular exposure to aircraft noise from McClellan-Palomar Airport. Therefore, impacts would be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 40 XIV. Population and Housing Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? Yes No No No b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? Yes No No No a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? Section 5.1, Effects Found Not Significant, of the PEIR includes a discussion of population and housing. As provided in the PEIR and 2019 Addendum, the Projects rely on population projections published in the Carlsbad Growth Management Plan and Growth Database, San Diego Association of Governments population projections, and the master plans from neighboring agencies. Therefore, the Projects would not generate additional population or cumulatively exceed official regional or local population projections. These circumstances remain unchanged based on the reduced water demand projections for the Projects included under the 2019 Addendum when compared to the 2012 PEIR. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? The Projects’ improvements would be constructed in existing and future dedicated public roadway rights-of-way, a small easement, and city-owned properties and would not require the displacement or relocation of existing residences. No impact would result. El Fuerte/Maerkle Motorized Valves Project 41 XV. Public Services Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: a) Fire protection? Yes No No No b) Police protection? Yes No No No c) Schools? Yes No No No d) Parks? Yes No No No e) Other public facilities? Yes No No No a) Fire protection? Section 5.1, Effects Found Not Significant, of the PEIR includes a discussion of the potential impacts of the Master Plans to public services, including fire protection. As provided in the PEIR and 2019 Addendum, the proposed Projects do not contain any residential uses or any other land uses that would result in an increased demand for public services. Additionally, the Projects would not exceed official regional or local population projections. Similar to the adopted Master Plans and Master Plans Updates, the size, capacity, and location of all facilities under the Projects would be based on the population and land use analysis based on forecasted growth identified in the Carlsbad General Plan (2015a), and systems would be sized appropriately to serve projected service populations. For these reasons, no impacts to public services, including fire protection services, would result. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Police protection? See response a). No impact would result to existing police services. El Fuerte/Maerkle Motorized Valves Project 42 c) Schools? See response a). No impact would result to schools or educational services. d) Parks? See response a). No impact would result to parks or recreational facilities. e) Other public facilities? See response a). No impact would result to other public facilities, such as libraries. XVI. Recreation Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? Yes No No No b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? Yes No No No a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? Section 5.1, Effects Found Not Significant, of the PEIR includes a discussion of the potential impacts of the Master Plans to recreation. As provided in the PEIR and 2019 Addendum, the approved CIP projects do not include any proposed residential uses or new recreational facilities or parks and their implementation would not impact the use of parks or other recreational facilities and would not require the construction or expansion of new such facilities. For this reason, the PEIR and 2019 Addendum concluded that no impact would result. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this El Fuerte/Maerkle Motorized Valves Project 43 analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? See response a). No impact would result. XVII. Transportation Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? Yes No No No b) Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? Yes No No No c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Yes No No No d) Result in inadequate emergency access? Yes No No No a) Conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? Section 4.12, Transportation/Traffic, of the PEIR provides an analysis of the proposed improvements covered under the adopted Master Plans. As described in in the PEIR and 2019 Addendum, the construction of the improvements would generate construction-related trips. However, construction traffic would only affect a limited area of the city in which they were located for a short time during construction of a particular project. The PEIR and 2019 Addendum determined that impacts related to temporary construction traffic would be less than significant with the incorporation of a traffic control plan during construction. Implementation of a traffic control plan is identified as a project design feature in the MMRP. Operation of the infrastructure improvements would not include substantial traffic generating uses beyond existing maintenance conditions. Due to the low volume of traffic generated by the proposed Project improvements (e.g., temporary construction-related trips, periodic inspections, and maintenance), the improvements would not El Fuerte/Maerkle Motorized Valves Project 44 degrade the traffic level of service in the vicinity or conflict with any applicable plans establishing measures of effectiveness for the performance of a circulation system. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? The Projects do not include new traffic generating uses that would increase vehicle trips beyond existing conditions. The PEIR and 2019 Addendum determined that the improvements would not conflict with CEQA Guidelines Section 15064.3(b) and no impact would occur. c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? The potential impacts associated with hazards due to a design feature were analyzed in the PEIR (Section 4.12) and 2019 Addendum. The PEIR and 2019 Addendum determined that impacts related to temporary traffic related hazards and local driveway access were less than significant with the incorporation of traffic control planning during construction. Implementation of a traffic control plan is identified as a project design feature in the adopted MMRP. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. d) Result in inadequate emergency access? Section 4.8 of the PEIR evaluated issues related to emergency response and evacuation. The PEIR and 2019 Addendum noted that construction activities associated with the CIP projects, particularly excavation and trenching activities associated with pipeline extensions or other improvements that are within roadway rights-of-way, may result in temporary, construction-related lane and road closures or detours. The El Fuerte site improvements would include construction in the roadway right-of-way and may require temporary closure of a traffic lane. As provided in the PEIR and 2019 Addendum, the city has committed to preparing a traffic control plan for applicable CIP projects. Implementation of a traffic control plan is identified as a project design feature in the MMRP. With implementation of a traffic control plan, the Projects would result in less than significant impacts on emergency response or evacuation plans. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. El Fuerte/Maerkle Motorized Valves Project 45 XVIII. Tribal Cultural Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: i. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k), or Yes No No No ii. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe. Yes No No No a) Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: i. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k)? Section 4.4, Cultural and Paleontological Resources, of the PEIR provides an assessment of potential impacts of the Master Plan improvements to known and undocumented archaeological resources. Since El Fuerte/Maerkle Motorized Valves Project 46 the certification of the PEIR, the city has updated its Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017) to reflect the city’s established standards of performance for cultural resources investigations following the city’s General Plan Update (2015a), the adoption of Assembly Bill 52 in 2014, and the corresponding amendments to Appendix G of the CEQA Guidelines (as amended). The city implemented several administrative updates to the PEIR’s adopted MMRP in the 2019 Addendum. These updates included updated CIP project references and the incorporation by reference of the city’s Tribal, Cultural, and Paleontological Resources Guidelines (2017). The NAHC was contacted for a Sacred Lands File search of the Maerkle valve site on March 10, 2022, to which the NAHC responded in a letter dated April 26, 2022 that the results were positive. The NAHC further noted to contact the La Jolla Band of Luiseno Indians and the San Luis Rey Band of Mission Indians for additional information regarding the positive results. No response from the La Jolla Band was received in response to CMWD outreach. CMWD met with representatives from the San Luis Rey Band and discussed the Maerkle site conditions and proposed activities. The San Luis Rey Band requested that spot-check monitoring occur for Maerkle valve site due to the cultural sensitivity of the project region. During vault excavation, spot check monitoring would be required. Full-time monitoring would not be required for vault excavation and no monitoring would be required for Maerkle pipeline replacements. Monitoring activities would be consistent with the 2017 guidelines to ensure potential impacts remain less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. ii. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe? Since the certification of the PEIR, the city adopted the 2017 guidelines to reflect the city’s established standards of performance for cultural resources investigations following the city’s General Plan Update (2015a), the adoption of Assembly Bill 52 in 2014, and the corresponding amendments to Appendix G of the CEQA Guidelines (as amended). As discussed in a), the NAHC indicated that tribal cultural resources may be present at the Maerkle valve site. Spot check monitoring would be conducted during vault excavation, as discussed with the San Luis Rey Band, and described above. Monitoring would not be required at the El Fuerte valve site based on the analysis provided in the PEIR and 2019 Addendum. Implementation of the preferred treatment options and mitigation measures, as detailed in the 2017 guidelines and 2019 Addendum, would ensure potential impacts on tribal cultural resources remain less than significant. Sections 15064.5(d) and (e) of the CEQA Guidelines assign special importance to human remains and specifies procedures to be used when Native American remains are discovered. As provided in Section 4.4 of the PEIR, these procedures are detailed under PRC, Section 5097.98. Any ground El Fuerte/Maerkle Motorized Valves Project 47 disturbing activities associated with implementation of the Projects, including grading, trenching, and excavation during construction of the Projects, would have the potential to unintentionally disturb human remains, resulting in a significant impact. Implementation of the required protocol in accordance with PRC Section 5097.98 and California State Health and Safety Code Section 7050.5, to be followed upon unintentional disturbance of human remains, in conjunction with Standard Treatment Measures 5 and 11 from the city’s 2017 guidelines would ensure potential impacts on human remains remain less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. XIX. Utilities and Service Systems Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? Yes No No No b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? Yes No No No c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? Yes No No No d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? Yes No No No El Fuerte/Maerkle Motorized Valves Project 48 Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste? Yes No No No a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? Section 5.1, Effects Found Not Significant, of the PEIR includes a discussion of the potential impacts of the Master Plans on existing utilities and service systems. As provided in the PEIR and 2019 Addendum, a primary purpose of the updating the Master Plans is to ensure adequate, effective, reliable, equitable and fiscally sound water, sewer, and recycled water service to current and projected future residential, commercial, and industrial customers through 2040. The Master Plans respond to projected growth in the service areas (refer to Population and Housing above) and would distribute existing and planned water supplies to meet existing and projected demand. Implementation of the Master Plans would not directly result in the need for new or expanded water and sewer supplies by introducing people or development to an area. The environmental impacts associated with the construction and operation of the proposed Projects are described throughout Section 4.2 of this Addendum. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? As provided in the 2019 Addendum, the Master Plan Updates were projected to result in a reduction in overall water use from 2012. The city’s water demands in 2012 was projected to increase to 21.4 mgd (23,968 afy) in 2050; however, according to the 2019 Addendum, based on updates to the city’s growth plan, the updated projected potable water demand at buildout is 18.5 mgd (20,720 afy), comparatively lower than the previous prediction in the PEIR. Therefore, the projected water demands under the Master Plan Updates, in which the Projects were previously considered, would be less than analyzed in 2012 and the impact would be less than significant. The changes to specific details of the Projects would not change the city’s water demand or supply as provided in the 2019 Addendum. El Fuerte/Maerkle Motorized Valves Project 49 c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? As provided above, no capacity increases would result under the Projects that would otherwise require an increase in treatment capacity at the Encina Wastewater Treatment Control Facility. No new impact would result. d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? As discussed in the PEIR (Section 4.8, Hazards and Hazardous Materials) and the 2019 Addendum, all demolition debris and construction waste associated with construction of CIP projects under the Master Plans would be properly handled and disposed of, in accordance with federal, state and local laws and regulations related to solid and hazardous waste. Moreover, the long-term operations of the proposed Projects are water infrastructure and would not generate solid waste that would significantly impact the permitted capacity of area landfills. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste? See item d). This impact would be less than significant. XX. Wildfire Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? If located in or near state responsibility areas or lands classified as very high fire hazard severity zones, would the project: a) Substantially impair an adopted emergency response plan or emergency evacuation plan? Yes No No No El Fuerte/Maerkle Motorized Valves Project 50 Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? Yes No No No c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? Yes No No No d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? Yes No No No a) Substantially impair an adopted emergency response plan or emergency evacuation plan? The PEIR (Section 4.8) and 2019 Addendum included analysis of wildfire hazards and impacts to emergency response. As provided, the service areas include mostly urbanized land; however, portions of the city service areas are located in areas classified as Very High Fire Hazard Severity Zones (CAL FIRE 2009). The Maerkle valve site (W-9) is located in a Very High Fire Hazard Severity Zone. As provided in the PEIR and 2019 Addendum, construction and design of all CIP projects would comply with the Uniform Fire Code (Title 24 Code of Federal Regulations, Part 9), which requires installation of sprinkler systems, fire-resistant building materials, standard roadway access widths, and other features to ensure that all above-ground structures are constructed with all reasonable fire safety features. Additionally, the city has committed to the multiple design features to minimize impacts related to wildfire: • Fire safety information will be disseminated to construction crews during regular safety meetings. Fire management techniques will be applied during project construction as deemed necessary by the lead agency and depending on-site vegetation and vegetation of surrounding areas. • A brush management plan will be incorporated during project construction by the city, CMWD, or a contractor, as necessary. Construction within areas of dense foliage during dry conditions will be avoided, when feasible. El Fuerte/Maerkle Motorized Valves Project 51 • In cases where avoidance is not feasible, necessary brush fire prevention and management practices will be incorporated. Specifics of the brush management program will be determined as site plans for the project are finalized. As provided in issue IX (f), the city has committed to preparing a traffic control plan for applicable CIP projects. Implementation of a traffic control plan is identified as a project design feature in the MMRP. Preparation of a brush management plan and dissemination of fire safety information to construction crews are also included as project design features in the MMRP, and would further minimize wildfire hazards for individual projects. In this context, the Projects would not substantially impair an adopted emergency response plan or emergency evacuation plan and the impact would be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? See response a). The Projects would be constructed within existing urbanized areas to serve existing and approved development. The physical improvements proposed by the Projects would not exacerbate existing wildfire risks that could otherwise expose existing populations to pollutant concentrations from a wildfire. The Projects would result in a less than significant impact. c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? The Projects would primarily be constructed in existing and future dedicated public rights of way and on city-owned properties and do not include any new electrical connections in high fire hazard zones. Preparation of a brush management plan and dissemination of fire safety information to construction crews are included as project design features in the MMRP, and would minimize wildfire hazards for individual projects. The physical improvements proposed under the Projects would serve existing development and would not exacerbate existing fire risks that could result in temporary or ongoing impacts to the environment. This is considered a less than significant impact. d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? See responses a) and b). The Projects would not exacerbate existing wildfire hazards that could otherwise result in downslope or downstream flooding or landslides, as a result of runoff, post-fire instability, or drainage changes. The Projects would be required to comply individually with the city’s engineering standards along with Carlsbad’s grading requirements, which would minimize any hazards related to landslides Compliance with existing regulations would minimize impacts to less than significant. El Fuerte/Maerkle Motorized Valves Project 52 XXI. Mandatory Findings of Significance Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Yes No No No b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are significant when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of past, present, and probable future projects)? Yes No No No c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? Yes No No No a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Sections 4.3 and 4.4 of the PEIR included consideration of potential cumulative impacts to biological and cultural resources. The 2019 Addendum identified less than significant impacts and did not contribute to more significant impacts than those identified in the PEIR. With the inclusion of the mitigation measures identified in the MMRP, the Projects would result in less than significant impacts. The physical improvements proposed under the Projects are not of a substantially different character than those certified in the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new El Fuerte/Maerkle Motorized Valves Project 53 significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are significant when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of past, present, and probable future projects)? Chapter 4 of the PEIR includes a consideration of potential cumulative impacts for each of the environmental resource topics considered. As provided in the 2019 Addendum, the city’s water demand in 2012 was projected to increase to 21.4 mgd (23,968 afy) at buildout; however, based on updates to the city’s growth plan, the updated projected potable water demand at buildout is 18.5 mgd (20,720 afy), comparatively lower than the previous predictions. Therefore, the projected water demands under the proposed Projects would be less than analyzed in 2012. Given that the activities proposed under the Projects have not substantially changed since the certification of the PEIR, the impact continues to be less than significant following application of the required mitigation. The analysis included in the PEIR and 2019 Addendum conservatively addresses the potential impacts of the Projects, since complete construction details were unknown. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? Section 5.3 and 5.4 of the PEIR address the Master Plans’ potential to result in growth inducement and significant and unavoidable impacts, respectively. Given that the Projects would involve the ongoing management, replacement, and upgrade of the city’s water, sanitary sewer, and recycled water infrastructure, no substantial adverse effects on human beings, either directly or indirectly, would result. This impact is considered less than significant. El Fuerte/Maerkle Motorized Valves Project 54 5.0 Applicable Project-specific Mitigation Measures The following mitigation measures from the certified 2012 PEIR MMRP and 2019 Addendum MMRP would be applicable to the impacts associated with the Projects. The City’s updated 2017 Tribal, Cultural, and Paleontological Resources Guidelines were incorporated into MMRP for the 2019 Addendum to reflect updates to treatment of tribal, cultural, and paleontological resources. No new significant impacts or increased severity in impacts that were not analyzed in the PEIR or 2019 Addendum have been identified; therefore, no additional new Project-specific mitigation is required. As identified in the associated environmental analysis sections above, the mitigation measures are applicable to specific components of the Projects. The biological and cultural mitigation measures identified below would only be applicable to the Maerkle valve site. Based on tribal outreach conducted by CMWD, monitoring at the Maerkle site would be limited to spot checks during vault excavation. While implementation of BMPs and other project design features identified in the previous MMRPs would be required at the El Fuerte site, no specific mitigation measures would be required. 5.1 Biological Resources Bio-1A Project-Level Biological Resource Surveys. During the design phase and prior to the construction of applicable CIP projects, the city and CMWD shall retain a qualified biologist to conduct project-level biological surveys. The surveys shall verify whether the project would occur on or in the immediate vicinity of natural habitat and habitat suitable for special status species. The surveys shall also identify if the project could result in direct or indirect impacts to natural habitat and special status species. The survey results shall be submitted to the city and CMWD to determine the need for further surveys and project- level analyses for subsequent CEQA documentation and the issuance of any discretionary actions or permits for the project. If the Quarry Creek Master Plan project covering CIP projects N-9, 55, and ES7 is ultimately approved and developed, the city and CMWD shall implement the specific mitigation requirements of the Quarry Creek Master Plan EIR (EIR 11-02) accordingly. Bio-1D Avoidance of Nesting Birds and Raptors. To prevent direct impacts to nesting birds, including raptors, protected under the federal MBTA and CDFG Code, the city and CMWD shall enforce the following: Prior to removal or damage of any active nests or any tree pruning or removal operations during the prime nesting seasons, that being from March 15 to May 30, a certified biologist shall survey the trees to determine if there are any active nests within 500 feet of the area of tree removal or pruning. If any active nests are located within 500 feet, no tree pruning or removal operations can occur until the nests are vacated or until the end of the prime breeding season, whichever occurs later. In addition, prior to any tree removal or pruning operations proposed outside of the prime nesting season but within the period of January 15 to September 15, a confirmation is required from a certified biologist that no disturbance to active nests or nesting activities would occur. Documentation from a certified biologist consistent with these requirements shall be submitted to the City Planner for review and approval. A note to this effect shall be placed on the construction plans. El Fuerte/Maerkle Motorized Valves Project 55 Bio-1E Pre-Construction Biological Resource Surveys. Prior to construction of CIP projects or portions of projects that will occur within disturbed or developed land, but will be sited immediately adjacent to an undeveloped open space area (i.e., an area supporting naturalized habitat, sensitive habitat, and/or habitat potentially suitable for special status species), the city and CMWD shall retain a qualified biologist to perform a pre-construction survey to verify existing biological resources adjacent to the project construction areas. The city and CMWD shall provide the biologist with a copy of the CIP project plans that clearly depict the construction work limits, including construction staging and storage areas, in order to determine which specific portion(s) of the project will require inspection of adjacent open space areas during the pre-construction survey. At minimum, the biologist shall perform a visual inspection of the adjacent open space area in order to characterize the existing habitat types and determine the likelihood for special status species to occur, including the coastal California gnatcatcher, migratory songbirds, and other bird species with the potential to breed in the area. The pre-construction survey results shall be submitted to the city and CMWD prior to construction in order to verify the need for the additional construction measures proposed within Bio-1F through Bio-1I below. Bio-1F Orange Construction Fencing. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the city and CMWD shall retain a qualified biologist to supervise the installation of temporary orange construction fencing, which clearly delineates the edge of the approved limits of grading and clearing, and the edges of environmentally sensitive areas that occur beyond the approved limits. This fencing shall be installed prior to construction and maintained for the duration of construction activity. Fencing shall be installed in a manner that does not impact habitats to be avoided. If work occurs beyond the fenced or demarcated limits of impact, all work shall cease until the problem has been remedied and mitigation identified. Temporary orange fencing shall be removed upon completion of construction of the project. Implementation of this measure shall be verified by the city prior to and concurrent with construction. Bio-1G Construction-Related Noise. Construction noise created during the general breeding season (January 15 to September 15) that could affect the breeding of the coastal California gnatcatcher, migratory songbirds, and other bird species associated with adjacent undeveloped areas shall be avoided. No loud construction noise (exceeding 60 dBA hourly average, adjusted for ambient noise levels, at the nesting site) may take place within 500 feet of active nesting sites during the general breeding season (January 15 through September 15). If it is confirmed through the implementation of mitigation measure Bio- 1E that the CIP project could result in construction-related noise impacts to breeding birds during the general breeding season, the city and CMWD shall retain a qualified biologist to monitor the construction operations. The biological monitor shall be present to monitor construction activities that occur adjacent to the undeveloped open space area potentially supporting breeding birds. The monitor shall verify that construction noise levels do not exceed 60 dBA hourly average and shall have the ability to halt construction work, if necessary, and confer with the city, USFWS, and CDFG to ensure the proper implementation of additional El Fuerte/Maerkle Motorized Valves Project 56 protection measures during construction. The biologist shall report any violation to the USFWS and/or CDFG within 24 hours of its occurrence. Bio-1H Construction Staging Areas. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the city and CMWD shall design final CIP project construction staging areas such that no staging areas shall be located within sensitive habitat areas. The construction contractor shall receive approval by the City Planning & Engineering Divisions prior to mobilization and staging of equipment outside of the project boundaries. Bio-1I Contractor Training. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the city and CMWD shall retain a qualified biologist to attend pre-construction meetings to inform construction crews of the sensitive resources and associated avoidance and/or minimization requirements. Bio-2A Habitat Compensation for Projects within the City of Carlsbad. If it is demonstrated through the implementation of mitigation measure Bio-1A that applicable CIP projects could directly impact sensitive natural communities, including Habitat Groups A, B, C, D, E, and F specified in Table 11 and Section D.6 of the City of Carlsbad HMP, the city and CMWD shall implement the following: 1. Mitigation for unavoidable impacts to Habitat Groups A, B, C, D, E, and F shall be provided according to the ratios specified below and consistent with Table 11 and Section D.6 of the City of Carlsbad HMP: HMP Habitat Mitigation Ratios Habitat Group and Type Mitigation Ratio A. Coastal salt marsh, alkali marsh, freshwater marsh, estuarine, salt pan/mudflats, riparian forest, riparian woodland, riparian scrub, vernal pools, disturbed wetlands, flood channel, Engelmann oak woodland, coast live oak woodland No net loss; mitigation varies by type of replacement habitat B. Beach, southern coastal bluff scrub, maritime succulent scrub, southern maritime chaparral, native grassland 3:1 C. Coastal sage scrub occupied by coastal California gnatcatcher 2:1 D. Coastal sage scrub unoccupied by coastal California gnatcatcher, coastal sage/chaparral mix, chaparral (excluding southern maritime chaparral) 1:1 E. Non-native grassland 0.5:1 F. Disturbed lands, eucalyptus woodland, agriculture 0.01:1 2. Impacts to Habitat Groups D, E, and F shall be mitigated at the Lake Calavera Mitigation Bank in accordance with Appendix B of the City of Carlsbad HMP for covered city projects that are eligible to mitigate impacts at the Lake Calavera Mitigation Bank. El Fuerte/Maerkle Motorized Valves Project 57 3. Impacts to Habitat Groups A, B, and C shall be to the maximum extent practicable through project-level siting during CIP project design and trenchless pipeline installation methods (e.g., jack and bore, horizontal directional drilling) during CIP project construction. 4. Unavoidable impacts to Habitat Groups A, B, and C shall be mitigated in-kind through implementation of any one or combination of the following measures, as approved and/or amended by the USFWS, USACE, RWQCB, and/or CDFG, if applicable: a. On site as creation of new habitat within avoided and preserved areas at the CIP project site; b. On site as restoration of existing habitat within temporary impact areas and/or avoided and preserved areas at the CIP project site; c. On site as enhancement of existing habitat within avoided and preserved areas at the CIP project site; d. Off site as purchase of habitat credits within an approved mitigation bank(s) (e.g., Carlsbad Oaks Conservation Bank, North County Habitat Bank); e. Off site as habitat preservation, creation, restoration, and/or enhancement within other properties or approved mitigation programs available at the time of grading; or f. A combination of the above. g. In the coastal zone, impacts to Habitat Groups A, B, and C shall be mitigated in accordance with the ratios described in Section D.7 of the HMP and shall include at a minimum a 1:1 creation (or substantial restoration when allowed) component to ensure no net loss of habitat. The remainder of the mitigation obligation may be satisfied pursuant to the provisions of the HMP. The proposed mitigation for impacts to Habitat Grounds A, B, and C in the coastal zone is subject to review by the California Coastal Commission. 5. On- or off-site creation, restoration, and/or enhancement mitigation for habitat groups A, B, and C shall consist of the following: a. For Habitat Group A types, including riparian and wetland sensitive natural communities (e.g., riparian forest, riparian woodland, riparian scrub, disturbed wetlands, coast live oak woodland), the city or CMWD shall prepare a Riparian/Wetland Habitat Restoration Plan detailing the specific riparian/wetland creation, restoration, and/or enhancement measures to be implemented as project mitigation. The Riparian/Wetland Habitat Restoration Plan shall be approved by the USFWS, USACE, RWQCB, and/or CDFG, as appropriate, prior to vegetation clearing, grading, and/or construction activities. El Fuerte/Maerkle Motorized Valves Project 58 b. For Habitat Group B types, including upland sensitive natural communities (e.g., maritime succulent scrub, southern maritime chaparral, native grassland), the city or CMWD shall prepare an Upland Habitat Restoration Plan detailing the specific upland habitat creation, restoration, and/or enhancement measures to be implemented as project mitigation. The Upland Habitat Restoration Plan shall be approved by the USFWS and CDFG prior to vegetation clearing, grading, and/or construction activities. c. For Habitat Group C types (occupied Coastal Sage Scrub), the city or CMWD shall prepare a Coastal Sage Scrub Habitat Restoration Plan detailing the specific coastal sage scrub habitat creation, restoration, and/or enhancement measures to be implemented as project mitigation. The Coastal Sage Scrub Habitat Restoration Plan shall be approved by the USFWS and CDFG prior to vegetation clearing, grading, and/or construction activities. d. The restoration plans for Habitat Groups A, B, and C shall include a five-year maintenance and monitoring program with a requirement to meet city and Wildlife Agencies approved success criteria. 6. Any upland or riparian/wetland habitat impacts that occur beyond the approved work limits of any CIP project shall be mitigated at a higher ratio to be negotiated with the USFWS, USACE, RWQCB, and/or CDFG. 7. If the Quarry Creek Master Plan project covering CIP projects N-9, 55, and ES7 is ultimately approved and developed, the city and CMWD shall implement the specific mitigation requirements of the Quarry Creek Master Plan EIR (EIR 11-02) accordingly. 5.2 Cultural Resources Cul-1 Cultural Resources Investigation. For the CIP projects proposed in close proximity to a known cultural resource or projects that would result in ground-disturbing activities in a previously undisturbed area, a project-level cultural resources investigation shall be conducted by a qualified cultural resource professional as defined in the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017) (2017 Guidelines) The cultural resources investigation shall include: 1. A CIP project site-specific review of the records search data at the South Coastal Information Center shall be conducted to determine if the CIP project site has been subjected to a professional survey. a. If a current cultural resources report addressing potential impacts on cultural resources is available, the city or CMWD shall implement the mitigation measures provided within the report. In the event that a current and valid report is not available, or if the entirety of the CIP project site has not been professionally surveyed, then an updated records search shall be performed. El Fuerte/Maerkle Motorized Valves Project 59 b. In accordance with the 2017 Guidelines, the city or CMWD shall contact the NAHC and local tribal governments for input on the project in order to identify any additional Native American resources that may not be included in the records search. 2. For those CIP project site(s) not addressed by a current cultural resources report (produced within five years of project proposal), a project-level Phase I Cultural Resources Survey shall be prepared in accordance with the 2017 Guidelines. Updates for all resources encountered during the Phase I survey shall be recorded using Department of Parks and Recreation (DPR) 523 forms in accordance with all applicable regulations. Resources shall be evaluated for significance and eligibility for inclusion in all applicable historic registers using methods such as, but not limited to, subsurface testing and/or archival research. Any subsurface testing would be monitored by an appropriate Native American representative. 3. In the event that such resources are found to be historical resources pursuant to CEQA, potential adverse impacts must be analyzed as stated in PRC Sections 21084.1 and 21083.2(l). Suitable mitigation for significant effects on archaeological resources are outlined in Section 15126.4(b)(3) as well as the 2017 Guidelines. The city or CMWD shall be responsible for implementing the methods for eliminating or substantially reducing impacts on resources as recommended by the archeologist and in consultation with the Native American Tribe. Such methods could include, but are not limited to: a. Planning construction to avoid archaeological sites; b. Incorporation of sites within parks, greenspace, or other open space; c. Capping or covering a site with a layer of soil before building on the site; d. Deeding the site into a permanent conservation easement; e. Excavation (Data Recovery) of archaeological resources; and/or f. Construction monitoring by a qualified professional and appropriate Native American monitors as identified through consultation with the NAHC or Native American Tribe. The monitor(s) shall be present at all pre- construction meetings. 4. If, as a result of Cul 1 -3, it is determined that a CIP project site requires monitoring by a Native American Tribe, then the city or CMWD shall enter into a Pre-Excavation Agreement or Cultural Resource Treatment and Monitoring Agreement with the appropriate Native American Tribe prior to the commencement of earth disturbing activities and consistent with the 2017 Guidelines. The results of the cultural resources investigation shall be complied into a technical report or memorandum and submitted to the city or CMWD and the South Coastal Information Center.

(HELIX) for the proposed Carlsbad Municipal Water District (District) Maerkle Motorized Valves Project (project), located in the City of Carlsbad (City), San Diego County, California. Activities would include the installation of a new underground vault approximately 50 feet southwest of the existing vault, and the installation of associated piping. The purpose of this report is to document the existing biological conditions within the project site plus a 500-foot buffer (study area), which encompasses approximately 20.8 acres, and provide an analysis of potential impacts on sensitive biological resources with respect to local, state, and federal policy. This report provides the biological resources technical documentation necessary for review under California Environmental Quality Act (CEQA) by the District. PROJECT LOCATION The project site is located south of State Route 78 and north of Agua Hedionda Creek, within an unsectioned portion of the Agua Hedionda land grant, in Township 12 South, Range 4 West on the San Luis Rey U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle, north of Los Monos Canyon (Figures 1 and 2, Regional Location and USGS Topography, respectively). The project site is located north of Sunny Creek Road, adjacent to Squires Reservoir (Figure 3, Aerial Photograph). The study area does not overlap with any U.S. Fish and Wildlife Service (USFWS)-designated critical habitat (USFWS 2022a). PROJECT DESCRIPTION The project involves the replacement of two existing isolation valves and piping with new motorized valves and piping, which would automate water system operations at this location (Figure 4, Site Plan). The existing 24-inch and 42-inch valves divert water into the 10-million-gallon tank and the 200-million- Letter to Mr. Sean Diaz Page 2 of 25 March 30, 2022 gallon reservoir. The new valves are to be installed in a new underground vault at the base of the slope to make it easier to access the valves and improve worker safety. Specific staging areas have not yet been identified; staging areas would be located within developed locations. In addition, project design features for the avoidance of sensitive biological resources have been incorporated as fundamental components of the project. Facility improvements at the Maerkle Reservoir are included as CIP project W-9 (50091) in the August 2019 Addendum to the Program Environmental Impact Report (PEIR) for the 2012 CMWD Water Master Plans Update (SCH No. 2012021006; 2019 Addendum), as well as the PEIR itself as Project R7. The PEIR found that Project R7 would not have biological impacts because it involves repair, maintenance, replacements, upsize, improvements, and/or other minor modifications to existing facilities, and is located entirely within, and surrounded by, existing disturbed and/or developed land. However, the improvements were described in the PEIR as replacing joint sealing in the 10 MG tank and adding security lights and cameras along the access road, gates, and site. Excavation and/or ground disturbance was not assumed in the PEIR but is required for the project. CIP projects were analyzed in the City of Carlsbad Sewer Master Plan and Carlsbad Municipal Water District Water and Recycled Water Master Plans Update Program Environmental Impact Report (PEIR) & Addendum (EIR 12-01; SCH No. 2012021006). This project is included in the CIP as project W-9, which was included in the 2019 Addendum to the PEIR. METHODS Project evaluation included a review of existing information and field surveys. This section discusses the methods used to evaluate the biological resources present within the study area. Literature Review Prior to conducting biological field surveys, HELIX performed a thorough review of relevant maps, databases, and literature pertaining to the biological resources known to occur within the study area. Recent and historical aerial imagery, USGS topographic maps, soils maps (Natural Resource Conservation Service [NRCS] 2022), and other maps of the study area and vicinity were acquired and reviewed to obtain updated information on the natural environmental setting. In addition, HELIX conducted a query of special-status species and habitats databases, including the USFWS species records (USFWS 2022b), California Department of Fish and Wildlife (CDFW) California Natural Diversity Database (CNDDB; CDFW 2022), Calflora database (Calflora 2022), SanBIOS and California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants (CNPS 2022). The USFWS’ National Wetlands Inventory (NWI) was also reviewed (USFWS 2022c). Any recorded locations of species, habitat types, wetlands, and other resources were mapped and overlain onto aerial imagery using Geographic Information Systems (GIS). Biological Surveys General Biological Survey A general biological survey of the study area was conducted by HELIX biologist Mandy Mathews on March 10, 2022. Vegetation was mapped on a 1"=200' scale aerial of the site. A minimum mapping unit Letter to Mr. Sean Diaz Page 3 of 25 March 30, 2022 size of 0.1 acre was used when mapping upland habitat. The study area was surveyed on foot and with the aid of binoculars. Plant and animal species observed or otherwise detected were recorded in field notebooks (Attachments A and B). Habitat suitability and potential for occurrence were assessed for special-status species known to the region (Attachments C and D). Animal identifications were made in the field by direct, visual observation or indirectly by detection of calls, burrows, tracks, or scat. Plant identifications were made in the field or in the lab through comparison with photographs. Representative site photos are located in Attachment E. Survey Limitations Noted animal species were identified by direct observation, vocalizations, or the observance of scat, tracks, or other signs. However, the lists of species identified are not necessarily comprehensive accounts of all species that utilize the project site, as species that are nocturnal, secretive, or seasonally restricted may not have been observed. Those species that are special-status and have the potential to occur in the project site are still addressed in this report. Nomenclature Nomenclature for this report is taken from Holland (1986) and Oberbauer (2008) for vegetation communities; Baldwin et al. (2012) for plants; North American Butterfly Association (2021) for butterflies; Society for the Study of Amphibians and Reptiles (2022) for reptiles and amphibians; American Ornithological Society (2021) for birds; and Bradley et al. (2014) for mammals. Plant species status is from the CNPS Rare Plant Inventory (2022a) and CDFW (2022b). Animal species status is from the CDFW (2022c). EXISTING CONDITIONS General Land Uses The study area is generally located within the northern portion of the City of Carlsbad, which is a coastal area situated in northern San Diego County. The general area is predominantly characterized by residential development to the northwest, agricultural land to the west, and undeveloped land to the north and south (Figure 3). Land uses that characterize the project site and surrounding area include residential development, agriculture, and water conveyance infrastructure. Topography and Soils Elevations in the study area range from approximately 400 to 520 feet above mean sea level. The project site area is generally flat, with the study area sloping down towards the southwest. One soil type has been mapped in the study area (Figure 5, Soils): Cieneba coarse sandy loam, 5 to 15 percent slopes, eroded. Vegetation Communities Four vegetation communities/habitat types occur in the study area, as presented in Table 1, Vegetation Communities/Habitat Types, and shown on Figure 6, Vegetation and Sensitive Resources. The numeric Letter to Mr. Sean Diaz Page 4 of 25 March 30, 2022 codes in parentheses following each community/habitat type name are taken from the Holland (Holland 1986) and Oberbauer (2008) classification systems. Table 1 VEGETATION COMMUNITIES/HABITAT TYPES Vegetation Communities/Habitat Types Study Area (acres)1 Diegan Coastal Sage Scrub (including disturbed and restored; 32500) 8.39 Eucalyptus Woodland (79100) 0.37 Disturbed Habitat (11300) 6.33 Urban/Developed (12000) 5.70 TOTAL 20.79 1 The study area extends 500 feet from the proposed project. Diegan Coastal Sage Scrub (including Restored and Disturbed) Coastal sage scrub is one of the two major shrub types that occur in southern California, occupying xeric sites characterized by shallow soils (the other is chaparral). Four distinct coastal sage scrub geographical associations (northern, central, Venturan, and Diegan) are recognized along the California coast. Diegan coastal sage scrub typically consists of low-growing, soft woody sub-shrubs, up to one meter in height, that bloom in the winter and early spring. The community commonly occurs on low moisture availability sites characterized by steep xeric slopes or clay-rich soils that have high water retention. Diegan coastal sage scrub occurs to the west and south of the project site, outside of proposed impacts but within the study area. Dominants of this community observed on-site consist primarily of California buckwheat (Eriogonum fasciculatum), California sagebrush (Artemisia californica), and laurel sumac (Malosma laurina). Restored Diegan coastal sage scrub occurs on the slopes surrounding the 10-million-gallon tank and mainly consists of San Diego sunflower (Bahiopsis laciniata), California sagebrush, and California buckwheat. Disturbed Diegan coastal sage scrub occurs west and north of the project site and consists of California sagebrush, California buckwheat, tocalote (Centaurea melitensis), short-pod mustard (Hirschfeldia incana), and crown daisy (Glebionis coronaria). Eucalyptus Woodland Eucalyptus woodland is dominated by eucalyptus (Eucalyptus sp.), an introduced species that has often been planted purposely for wind-blocking, ornamental, and hardwood production purposes. Most groves are monotypic, with the most common species being either the blue gum (Eucalyptus globulus) or red gum (E. camaldulensis ssp. obtusa). The understory within well-established groves is usually very sparse due to the closed canopy and allelopathic nature of the abundant leaf and bark litter. If sufficient moisture is available, this species becomes naturalized and is able to reproduce and expand its range. The sparse understory offers only limited wildlife habitat; however, as a wildlife habitat, these woodlands provide excellent nesting sites for a variety of raptors, including red-shouldered hawks (Buteo lineatus). During winter migrations, a large variety of warblers may be found feeding on the insects that are attracted to the eucalyptus flowers. Eucalyptus trees with active raptor nests are considered sensitive. Within the study area, a small stand of eucalyptus woodland occurs east of the project site and is dominated by blue gum and spider gum (Eucalyptus conferruminate). Letter to Mr. Sean Diaz Page 5 of 25 March 30, 2022 Disturbed Habitat Disturbed habitat includes land cleared of vegetation (e.g., dirt roads), land containing a preponderance of non-native plant species, such as ornamentals or ruderal exotic species that take advantage of disturbance (previously cleared or abandoned landscaping), or land showing signs of past or present animal usage that removes any capability of providing viable habitat. Disturbed habitat consists of bare ground with scattered annual non-native species, including mustard (Brassica ssp.), Russian thistle (Salsola tragus), and filaree (Erodium cicutarium). Disturbed habitat occurs atop the 10-million-gallon tank, to the north and west of the 10-million-gallon tank, and in smaller patches along paved roadways. The dominant species within these areas are short-pod mustard, filaree, and crown daisy. Urban/Developed Urban/developed land includes areas that have been constructed upon or otherwise covered with a permanent, unnatural surface and may include, for example, structures, pavement, irrigated landscaping, or hardscape to the extent that no natural land is evident. These areas no longer support native or naturalized vegetation. Developed portions of the study area consist of paved roads, residential developments, and access paths with compacted soil/gravel. Plants A total of 46 plant species were observed within the study area during the general biological survey, of which 22 (48 percent) are non-native species (Appendix A, Plant Species Observed). The predominance of non-native species is indicative of the high degree of disturbance as a result of historical and current uses of the study area. Animals A total of 32 animal species were observed/detected within the study area during the general biological survey and focused species surveys: six invertebrates, one reptile, 22 bird species, and three mammals (Appendix B; Animal Species Observed or Detected). Sensitive Resources Sensitive Vegetation Communities/Habitats Sensitive vegetation communities/habitat types are defined as land that supports unique vegetation communities or the habitats of rare or endangered species or subspecies of animals or plants as defined by Section 15380 of the State CEQA Guidelines. The CDFW evaluates the rarity of natural communities using the NatureServe’s Heritage Methodology (Faber-Langendoen et al. 2012), in which communities are given a G (global) and S (State) rank based on their degree of imperilment (as measured by rarity, trends, and threats). Communities are assigned an overall rank of 1 through 5, with 1 being considered very rare and threatened and 5 being considered demonstrably secure. Communities with a Rarity Ranking of S1 (critically imperiled), S2 (imperiled), or S3 (vulnerable) are considered sensitive by the CDFW. Letter to Mr. Sean Diaz Page 6 of 25 March 30, 2022 Diegan coastal sage scrub (including disturbed) has a ranking of S3.1; therefore, it is considered a sensitive vegetation community (CDFW 2022b). Under the City’s HMP, Diegan coastal sage scrub, occupied by coastal California gnatcatcher, is classified as Group C, which requires maximum avoidance and on-site conservation as practical (Carlsbad 2022). Diegan coastal sage scrub that is unoccupied is classified as Group D, and disturbed habitat and eucalyptus woodland are classified as Group F. Urban/developed lands do not meet the definition of sensitive habitat under CEQA or the City’s HMP. Special Status Plant Species Special status plant species have been afforded special status and/or recognition by the USFWS and/or CDFW. They may also be included in the CNPS’ Inventory of Rare and Endangered Plants. Their status is often based on one or more of three distributional attributes: geographic range, habitat specificity, and/or population size. Sensitive species are those considered unusual or limited in that they are: (1) only found in the region; (2) a local representative of a species or association of species not otherwise found in the region; or (3) severely depleted within their ranges or within the region. No special status plant species were observed within the study area. Sensitive Plant Species with Potential to Occur Additional special-status plant species that were not observed but may have potential to occur within the study area are listed in Appendix C, Special Status Plant Species Observed or with Potential to Occur. No additional plant species have a high potential to occur based on geographic range, elevation range, and/or lack of suitable habitat in the study area. Special Status Animal Species Special status animal species include those that have been afforded special status and/or recognition by the USFWS and/or CDFW. In general, the principal reason an individual taxon (species or subspecies) is given such recognition is the documented or perceived decline or limitations of its population size or geographical extent and/or distribution, and in most cases, resulting from habitat loss. Two special-status animal species were observed within or adjacent to the study area during the 2022 project biological survey (Figure 6), coastal California gnatcatcher (Polioptila californica californica) and California horned lark (Eremophila alpestris actia). Coastal California gnatcatcher (Polioptila californica californica) Status: FT/SSC Distribution: In San Diego County, occurs throughout coastal lowlands Habitat(s): Coastal sage scrub Status on site: A pair of coastal California gnatcatchers was observed within Diegan coastal sage scrub approximately 320 feet southwest of the proposed project site. California horned lark (Eremophila alpestris actia) Status: --/WL Distribution: Observed year-round scattered throughout San Diego County Habitat(s): Coastal strand, arid grasslands, and sandy desert floors Status on site: Three California horned larks were observed within sparse disturbed habitat atop the 10- million-gallon tank, approximately 125 feet northeast of the proposed project site. Letter to Mr. Sean Diaz Page 7 of 25 March 30, 2022 Sensitive Animal Species with Potential to Occur Special status animal species that were not observed or otherwise detected but determined to have some potential to occur on-site are included in Appendix D, Special Status Animal Species Observed or with Potential to Occur. The species are grouped into invertebrates and vertebrates (amphibians, reptiles, birds, and mammals) and alphabetized by scientific name. One species analyzed has a high potential to occur: Belding’s orange-throated whiptail (Aspidoscelis hyperythrus beldingi). Orange-throated whiptail, a Watch List species, has been reported within disturbed habitat, as recent as 2017. No other species have a high potential to occur based on geographic range, elevation range, and/or lack of suitable habitat in the project site. Nesting Birds Trees and shrubs both within and adjacent to the project site could provide suitable nesting habitat for numerous bird species known to the region. Raptor Foraging One raptor species was observed during the general biological survey: red-tailed hawk (Buteo jamaicensis). Additionally, several other species have the potential to forage in the project vicinity. The project site itself does not provide raptor habitat due to the small footprint and lack of suitable areas to perch or nest. Extensive raptor foraging habitat occurs immediately adjacent to the project vicinity within undeveloped areas surrounding the project, as well as nesting habitat within tall trees or structures nearby. Wildlife Corridor/Core Wildlife Areas Wildlife corridors connect otherwise isolated pieces of habitat and allow movement or dispersal of plants and animals. Wildlife corridors can be local or regional in scale and may function in different ways depending on species and time of year. Wildlife corridors represent areas where wildlife movement is concentrated due to natural or manufactured constraints. Local corridors provide access to resources such as food, water, and shelter. Animals can use these corridors, such as hillsides and tributary drainages to main drainages, to travel among different habitats (i.e., riparian and upland habitats). Some animals require riparian habitat for breeding and upland habitat for burrowing. Regional corridors provide these functions and also link two or more large areas of open space. Regional corridors also provide avenues for wildlife dispersal, migration, and contact between otherwise distinct populations. The project is located within the Core 5 Focus Planning Area (FPA) of the Carlsbad Habitat Management Plan (HMP; Carlsbad 2004). The western portion of the study area is within Linkage C, which supports a mixture of agricultural fields and native habitat and connects Core 5 to Core 3 to the west. The project site occurs within a maintained area adjacent to residential development and roadways/public right-of- way (ROW). The project site is located in an existing disturbed area, which reduces its value as a wildlife corridor or core wildlife area, although it may function as a stopover site for migrating bird species. The Dawson-Los Monos Canyon Reserve, an existing Hardline Conservation Area south of Sunny Creek Road, provides protected natural habitat which is more likely to support local and regional wildlife movement and live-in habitat than the project site. No other identified linkages occur within or adjacent to the study area (South Coast Wildlands 2008). Letter to Mr. Sean Diaz Page 8 of 25 March 30, 2022 REGULATORY FRAMEWORK Biological resources in the project site are subject to regulatory review by federal, state, and local agencies. Under CEQA, impacts associated with a proposed project are assessed with regard to significance criteria determined by the CEQA Lead Agency (in this case, the District) pursuant to CEQA Guidelines. Biological resources-related laws and regulations that apply to the project analysis include the Federal Endangered Species Act (FESA), Migratory Bird Treaty Act (MBTA), CWA, CEQA, California Endangered Species Act (CESA), and CFG Code. Federal Federal Endangered Species Act Administered by the USFWS, the federal ESA provides the legal framework for the listing and protection of species (and their habitats) that are identified as being endangered or threatened with extinction. Actions that jeopardize endangered or threatened species and the habitats upon which they rely are considered take under the ESA. Section 9(a) of the ESA defines take as “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to engage in any such conduct.” “Harm” and “harass” are further defined in federal regulations and case law to include actions that adversely impair or disrupt a listed species’ behavioral patterns. Sections 7 and 4(d) of the Federal ESA regulate actions that could jeopardize endangered or threatened species. Section 7, administered by the USFWS, describes a process of Federal interagency consultation for use when Federal actions may adversely affect listed species. A Section 7 Consultation (formal or informal) is required when there is a nexus between a listed species’ use of a site and if the project is funded (wholly or in part) by federal funding. A biological assessment is required for any major construction or maintenance activity, if it may affect listed species. Take can be authorized via a letter of Biological Opinion, issued by the USFWS, for non-marine related listed species issues. Identified by the USFWS, critical habitat is defined as areas of land that are considered necessary for endangered or threatened species to recover. The ultimate goal is to restore healthy populations of listed species within their native habitat so they can be removed from the list of threatened or endangered species. Once an area is designated as critical habitat pursuant to the federal ESA, all federal agencies must consult with the USFWS to ensure that any action they authorize, fund, or carry out is not likely to result in the destruction or adverse modification of the critical habitat. Migratory Bird Treaty Act All migratory bird species that are native to the United States or its territories are protected under the federal MBTA, as amended under the Migratory Bird Treaty Reform Act of 2004 (FR Doc. 05-5127). The MBTA is generally protective of migratory birds but does not actually stipulate the type of protection required. In common practice, the MBTA is used to place restrictions on the disturbance of active bird nests during the nesting season (generally February 1 to August 31). In addition, the USFWS commonly places restrictions on disturbances allowed near active raptor nests. Letter to Mr. Sean Diaz Page 9 of 25 March 30, 2022 State Regulations California Environmental Quality Act Primary environmental legislation in California is found in CEQA and its implementing guidelines (State CEQA Guidelines), which require that projects with potential adverse effects (i.e., impacts) on the environment undergo environmental review. Adverse environmental impacts are typically mitigated as a result of the environmental review process in accordance with existing laws and regulations. California Endangered Species Act The CESA established that it is state policy to conserve, protect, restore, and enhance state endangered species and their habitats. Under state law, plant and animal species may be formally designated rare, threatened, or endangered by official listing by the California Fish and Game Commission. The CESA authorizes that private entities may “take” plant or wildlife species listed as endangered or threatened under the FESA and CESA, pursuant to a federal Incidental Take Permit if the CDFW certifies that the incidental take is consistent with CESA (CFG Code Section 2080.1[a]). For state-only listed species, Section 2081 of CFG Code authorizes the CDFW to issue an Incidental Take Permit for state-listed threatened and endangered species if specific criteria are met. The Carlsbad HMP was prepared pursuant to Section 2081 of the CESA, and the City was issued an umbrella Section 2081 ITP from the CDFG authorizing take of multiple state listed species. Native Plant Protection Act Sections 1900–1913 of the CFG Code (Native Plant Protection Act; NPPA) direct the CDFW to carry out the state legislature’s intent to “…preserve, protect, and enhance endangered or rare native plants of this state.” The NPPA gives the California Fish and Game Commission the power to designate native plants as “endangered” or “rare” and protect endangered and rare plants from take. California Fish and Game Code The CFG Code provides specific protection and listing for several types of biological resources. Section 1600 of CFG Code requires a Streambed Alteration Agreement (SAA) for any activity that would alter the flow, change, or use any material from the bed, channel, or bank of any perennial, intermittent, or ephemeral river, stream, and/or lake. Typical activities that require an SAA include excavation or fill placed within a channel, vegetation clearing, structures for diversion of water, installation of culverts and bridge supports, cofferdams for construction dewatering, and bank reinforcement. Notification is required prior to any such activities. Pursuant to CFG Code Section 3503, it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by this code or any regulation made pursuant thereto. Raptors and owls and their active nests are protected by CFG Code Section 3503.5, which states that it is unlawful to take, possess, or destroy any birds of prey or to take, possess, or destroy the nest or eggs of any such bird unless authorized by the CDFW. Section 3513 states that it is unlawful to take or possess any migratory non-game bird as designated in the MBTA. These regulations could require that construction activities (particularly vegetation removal or construction near nests) be reduced or eliminated during critical phases of the nesting cycle unless surveys by a qualified biologist demonstrate that nests, eggs, or nesting birds will not be disturbed, subject to approval by CDFW and/or USFWS. Letter to Mr. Sean Diaz Page 10 of 25 March 30, 2022 California Natural Community Conservation Planning Act of 1991 The NCCP Act is designed to conserve habitat-based natural communities at the ecosystem scale while accommodating compatible land uses in coordination with CESA. CDFW is the principal state agency implementing the NCCP Program. The Act established a process to allow for comprehensive, long-term, regional, multi-species, and habitat-based planning in a manner that satisfies the requirements of the state and FESAs (through a companion regional habitat conservation plan). The NCCP program has provided the framework for innovative efforts by the state, local governments, and private interests, to plan for the protection of regional biodiversity and the ecosystems upon which they depend. NCCPs seek to ensure the long-term conservation of multiple species, while allowing for compatible and appropriate economic activity to proceed. The Carlsbad HMP was prepared as part of the Multiple Habitat Conservation Program (MHCP) subregional planning pursuant to the NCCP Act. Local Regulations Multiple Habitat Conservation Program The MHCP is a comprehensive, multiple jurisdictional planning program, designed to develop an ecosystem preserve in northwestern San Diego County. Implementation of the regional preserve system is intended to protect viable populations of key sensitive plant and animal species and their habitats, while accommodating continued economic development and quality of life for residents of the North County region. The MHCP is one of several large multiple jurisdictional habitat planning efforts in San Diego County, each of which constitutes a subregional plan under the NCCP Act of 1991. The MHCP includes seven incorporated cities in northwestern San Diego County: Carlsbad, Encinitas, Escondido, Oceanside, San Marcos, Solana Beach, and Vista. These jurisdictions will implement their respective portions of the MHCP through citywide “subarea” plans, which describe the specific implementing mechanisms each city will institute for the MHCP. The goal of the MHCP is to conserve approximately 19,000 acres of habitat, of which roughly 8,800 acres (46 percent) are already in public ownership, and contribute toward the habitat preserve system for the protection of more than 80 rare, threatened, or endangered species. The Carlsbad HMP is the only approved and adopted Subarea Plan under the MHCP. Carlsbad Habitat Management Plan (HMP) The City approved the Carlsbad HMP in 2004 and adopted ordinance regulations in Chapter 21.210 of the Carlsbad Municipal Code as a condition of receiving approval from the CCC, an ITP from the USFWS pursuant to Section 10(a)(1)(B) of the FESA, and incidental take authorization from the CDFG pursuant to the CESA and Section 2835 of the CFG Code. Since its adoption, the Carlsbad HMP has allowed for citywide permits and the authorization for the incidental take of sensitive species in conjunction with private development projects, public projects, and other activities consistent with the HMP. The Carlsbad HMP has been successful in contributing toward the conservation of local habitats and recovery of regionally sensitive plant and animal species within Carlsbad. The HMP designates approximately 6,500 acres of the open space lands in Carlsbad for preservation based on its value as habitat for endangered animals and rare, unique, or sensitive plant species. The plan identifies how the City of Carlsbad can protect and maintain these lands while still allowing additional public and private development consistent with the General Plan and the Growth Management Plan. The purpose and intent of Chapter 21.210 of the Carlsbad Municipal Code in implementing the Carlsbad HMP are summarized below. Letter to Mr. Sean Diaz Page 11 of 25 March 30, 2022 Habitat Preservation and Management Requirements Chapter 21.210 of the Carlsbad Municipal Code requires all development to comply with the Carlsbad HMP as well as the implementing agreement, permit conditions, the MHCP, the NCCP and 10(a)(1)(B) permit conditions, and the requirements contained in Habitat Preservation and Management Requirements Ordinance. No grading is allowed to occur for projects in Carlsbad until all the processing and permitting requirements of this chapter are fulfilled. The purpose and intent of the Habitat Preservation and Management Requirements Ordinance are to: • Implement the goals and objectives of the land use and the open space/conservation elements of the Carlsbad General Plan; • Implement the Carlsbad HMP, the implementing agreement and conditions, the North County MHCP, the California NCCP and 10(a)(1)(B) permit conditions; • Preserve the diversity of natural habitats in Carlsbad and protect the rare and unique biological resources located within those habitats; • Assure that all development projects comply with the habitat preservation and conservation standards contained in the Carlsbad HMP; • Provide a process for permitting limited, incidental impacts to occur to natural habitat areas and the species located therein; and • Provide a process for allowing minor amendments from the habitat preservation and conservation standards under limited, specified circumstances. An HMP Permit is required to be obtained from the City for any development project which directly or indirectly impacts natural habitat within the Carlsbad HMP boundaries. Habitat conservation planning is processed as a Consistency Finding and requires concurrence from the USFWS and CDFW. Zone Level Recommendations The project is situated within Local Facilities Management Zone 15 (Zone 15) of the Carlsbad HMP planning area. The HMP Conservation Goals for Zone 15 are to establish, enhance, and maintain a viable habitat linkage across Linkage Area C to ensure connectivity for gnatcatchers and other HMP species between Core Areas 3 and 5 and to conserve the majority of sensitive habitats in or contiguous with biological core and linkage areas, including no net loss of wetland habitats and coastal sage scrub within Core Area 3 and Linkage Area C. The Standards Area within Zone 15 occurs within Linkage Area C, to the west of the project site, and does not apply to the project site. SIGNIFICANCE OF PROJECT IMPACTS AND PROPOSED MITIGATION This section describes potential direct and indirect impacts associated with the proposed project. Direct impacts immediately alter the affected biological resources such that those resources are eliminated temporarily or permanently. Proposed project activities would result in temporary impacts to Diegan coastal sage scrub, disturbed habitat, and urban/developed lands. Permanent impacts include an approximately 120-square foot vault. Letter to Mr. Sean Diaz Page 12 of 25 March 30, 2022 Criteria for Determining Impact Significance The significance of impacts to biological resources present, or those with potential to occur, was determined based on the sensitivity of the resource and the extent of the anticipated impacts. For certain highly sensitive resources (e.g., a federally listed species), any impact would be significant. Conversely, other resources that are of low sensitivity (e.g., species with a large, locally stable population in the County but declining elsewhere) could sustain some impact with a less than significant effect. According to Appendix F of the CEQA Guidelines, project impacts to biological resources would be considered significant if they would: (a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by CDFW or USFWS. (b) Have a substantial adverse effect on any riparian habitat or sensitive natural community identified by local or regional plans, policies, regulations, or by CDFW or USFWS. (c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the CWA (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling hydrological interruption, or other means. (d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species, or with an established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites. (e) Conflict with local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance. (f) Conflict with provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan. Issue 1: Special-Status Species Would the project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the CDFW or USFWS? Impact Analysis Special-Status Plant Species No federally or state listed species would be impacted by project activities. No sensitive plant species were mapped within the study area, and no other special-status or listed species has a high potential to occur within the project area. Letter to Mr. Sean Diaz Page 13 of 25 March 30, 2022 No special-status plant species are anticipated to be affected by project activities, as the project impact areas are restricted to an area of disturbed habitat and a small area of previously restored Diegan coastal sage scrub. As no direct impacts to sensitive plants are anticipated, no mitigation is required. Special-Status Animal Species If avoidance measures are not in place, the project could result in significant direct and/or indirect impacts to several special-status bird species during construction, as detailed further below. The coastal California gnatcatcher was observed within the study area, within 500 feet of the project site, and suitable habitat for this species occurs on-site. If avoidance measures are not in place, then project construction could result in potential significant noise-related indirect impacts on the coastal California gnatcatcher, if breeding individuals become displaced from their nests and fail to breed. The project incorporates PEIR mitigation measures Bio-1D through Bio-1I to ensure that potential direct or indirect impacts on the coastal California gnatcatcher are avoided. One other special-status bird was also detected within the study area: California horned lark, a State Watch List species. If avoidance measures are not in place, then project construction could result in potential significant direct impact and noise-related indirect impacts to special-status bird species, including tree-nesting raptors. The project is required to comply with the regulations and guidelines of the Carlsbad HMP, MBTA, and CFG Code. As such, the project must ensure no direct or indirect impacts to nesting birds and tree-nesting raptors. The project incorporates PEIR mitigation measures Bio-1D through Bio-1I to ensure that no indirect impacts occur to nesting birds and tree-nesting raptors during project construction. Belding’s orange-throated whiptail is a State Species of Special Concern and is covered under the City’s HMP. Although not observed on-site during the general biological survey, this species has a high potential to occur within the proposed project site due to the presence of suitable coastal sage scrub and disturbed habitats. If avoidance measures are not in place, then project construction could result in potential significant direct impacts to this species. The project incorporates PEIR mitigation measure Bio- 2A to ensure that habitat-based mitigation mitigates for impacts to habitat supporting Belding’s orange- throated whiptail. Mitigation Measures Implementation of the following mitigation measures would ensure project consistency with the protection of any species identified as a candidate, sensitive, or special-status species. Bio-1D Avoidance of Nesting Birds and Raptors. To prevent direct impacts to nesting birds, including raptors, protected under the federal MBTA and CDFG Code, the City and CMWD shall enforce the following: Prior to removal or damage of any active nests or any tree pruning or removal operations during the prime nesting seasons, that being from March 15 to May 30, a certified biologist shall survey the trees to determine if there are any active nests within 500 feet of the area of tree removal or pruning. If any active nests are located within 500 feet, no tree pruning or removal operations can occur until the nests are vacated or until the end of the prime breeding season, whichever occurs later. In addition, prior to any tree removal or pruning operations proposed outside of the prime nesting season but within the period of January 15 to September 15, a confirmation is required from a certified biologist that no disturbance to active Letter to Mr. Sean Diaz Page 14 of 25 March 30, 2022 nests or nesting activities would occur. Documentation from a certified biologist consistent with these requirements shall be submitted to the City Planner for review and approval. A note to this effect shall be placed on the construction plans. Bio-1E Pre-Construction Biological Resource Surveys. Prior to the construction of CIP projects or portions of projects that will occur within disturbed or developed land, but will be sited immediately adjacent to an undeveloped open space area (i.e., an area supporting naturalized habitat, sensitive habitat, and/or habitat potentially suitable for special status species), the City and CMWD shall retain a qualified biologist to perform a pre-construction survey to verify existing biological resources adjacent to the project construction areas. The City and CMWD shall provide the biologist with a copy of the CIP project plans that clearly depict the construction work limits, including construction staging and storage areas, in order to determine which specific portion(s) of the project will require inspection of adjacent open space areas during the pre-construction survey. At a minimum, the biologist shall perform a visual inspection of the adjacent open space area in order to characterize the existing habitat types and determine the likelihood for special status species to occur, including the coastal California gnatcatcher, migratory songbirds, and other bird species with the potential to breed in the area. The pre-construction survey results shall be submitted to the City and CMWD prior to construction in order to verify the need for the additional construction measures proposed within Bio-1F through Bio-1I below. Bio-1F Orange Construction Fencing. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the City and CMWD shall retain a qualified biologist to supervise the installation of temporary orange construction fencing, which clearly delineates the edge of the approved limits of grading and clearing, and the edges of environmentally sensitive areas that occur beyond the approved limits. This fencing shall be installed prior to construction and maintained for the duration of construction activity. Fencing shall be installed in a manner that does not impact habitats to be avoided. If work occurs beyond the fenced or demarcated limits of impact, all work shall cease until the problem has been remedied and mitigation identified. Temporary orange fencing shall be removed upon completion of construction of the project. The City shall verify the implementation of this measure prior to and concurrent with construction. Bio-1G Construction-Related Noise. Construction noise created during the general breeding season (January 15 to September 15) that could affect the breeding of the coastal California gnatcatcher, migratory songbirds, and other bird species associated with adjacent undeveloped areas shall be avoided. No loud construction noise (exceeding 60 dBA hourly average, adjusted for ambient noise levels, at the nesting site) may take place within 500 feet of active nesting sites during the general breeding season (January 15 through September 15). If it is confirmed through the implementation of mitigation measure Bio- 1E that the CIP project could result in construction-related noise impacts to breeding birds during the general breeding season, the City and CMWD shall retain a qualified biologist to monitor the construction Letter to Mr. Sean Diaz Page 15 of 25 March 30, 2022 operations. The biological monitor shall be present to monitor construction activities that occur adjacent to the undeveloped open space area that potentially supports breeding birds. The monitor shall verify that construction noise levels do not exceed 60 dBA hourly average and shall have the ability to halt construction work, if necessary, and confer with the City, USFWS, and CDFG to ensure the proper implementation of additional protection measures during construction. The biologist shall report any violation to the USFWS and/or CDFG within 24 hours of its occurrence. Bio-1H Construction Staging Areas. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the City and CMWD shall design final CIP project construction staging areas such that no staging areas shall be located within sensitive habitat areas. The construction contractor shall receive approval from the City Planning & Engineering Divisions prior to mobilization and staging of equipment outside of the project boundaries. Bio-1I Contractor Training. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the City and CMWD shall retain a qualified biologist to attend pre-construction meetings to inform construction crews of the sensitive resources and associated avoidance and/or minimization requirements. Conclusions Project implementation could result in significant impacts to nesting birds and raptors, including special- status avian species (i.e., coastal California gnatcatcher, California horned lark), with the potential to nest within or adjacent to the project site. Implementation of the mitigation measures detailed above would ensure that potential impacts are reduced to less than significant. Project implementation could also result in significant impacts to Belding’s orange-throated whiptail. Implementation of habitat-based mitigation discussed below would ensure that potential impacts are reduced to less than significant. Issue 2: Sensitive Natural Communities Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the CDFW or USFWS? Impact Analysis The proposed project would result in impacts to Diegan coastal sage scrub that was previously restored. Unoccupied Diegan coastal sage scrub is considered a sensitive natural community under the Carlsbad HMP, falling into Habitat Group D. Disturbed Habitat is Habitat Group F. Impacts to these habitats require mitigation per PEIR mitigation measure Bio-2A. Habitat impacts for the project are depicted on Figure 7, Vegetation and Sensitive Resources Impacts and summarized below within Table 2, Vegetation Community/Land Use Impacts. Letter to Mr. Sean Diaz Page 16 of 25 March 30, 2022 Table 2 VEGETATION COMMUNITY/LAND USE IMPACTS Vegetation Community Habitat Group Impacts (acres) Diegan Coastal Sage Scrub (unoccupied, including disturbed and restored) D 0.04 Disturbed Habitat F 0.04 TOTAL 0.08 Mitigation Measures Bio-2A Habitat Compensation for Projects within the City of Carlsbad. If it is demonstrated through the implementation of mitigation measure Bio-1A that applicable CIP projects could directly impact sensitive natural communities, including Habitat Groups A, B, C, D, E, and F specified in Table 11 and Section D.6 of the City of Carlsbad HMP, the City and CMWD shall implement the following: 1. Mitigation for unavoidable impacts to Habitat Groups A, B, C, D, E, and F shall be provided according to the ratios specified below and consistent with Table 11 and Section D.6 of the City of Carlsbad HMP: 2. Impacts to Habitat Groups D, E, and F shall be mitigated at the Lake Calavera Mitigation Bank in accordance with Appendix B of the City of Carlsbad HMP for covered city projects that are eligible to mitigate impacts at the Lake Calavera Mitigation Bank. The project will mitigate for impacts to 0.04 acre of coastal sage scrub and 0.04 acre of disturbed habitat with 0.04 acre (mitigation rounded to the nearest 0.01 acre) at the Lake Calavera Mitigation Bank. Letter to Mr. Sean Diaz Page 17 of 25 March 30, 2022 Conclusion Project implementation could result in significant impacts to coastal sage scrub and disturbed habitat, both of which are considered sensitive by the Carlsbad HMP. Implementation of the mitigation measure Bio-2A detailed above would ensure that potential impacts are reduced to less than significant. Issue 3: Jurisdictional Wetlands and Waterways Would the project have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the federal CWA (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Impact Analysis No jurisdictional wetlands or waterways occur within the project site or immediate surrounding area. Mitigation Measures No mitigation is required. Conclusion The project would not result in impacts to wetlands or waterways. Issue 4: Wildlife Movement and Nursery Sites Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory corridors, or impede the use of native wildlife nursery sites? Impact Analysis The project site is located within Core 5 of the Carlsbad HMP; however, the project is sited within existing disturbed and developed land that is subject to regular maintenance. As the project development has been sited within existing disturbed and developed areas and a very small (less than 0.1-acre) area of previously restored Diegan coastal sage scrub, the potential impact on wildlife movement and nursery sites would be less than significant, and no additional mitigation is required. Mitigation Measures No mitigation is required. Conclusion Project implementation would not result in significant impacts on wildlife movement and nursery sites. Less than significant impacts would occur, and mitigation is not required. Letter to Mr. Sean Diaz Page 18 of 25 March 30, 2022 Issue 5: Local Policies and Ordinances Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Impact Analysis No local policies or ordinances pertaining to biological resources are applicable to the project except for the Carlsbad HMP, which is discussed below. The project would primarily occur within the existing disturbed areas and public road ROW. No impact or conflict would occur. Mitigation Measures No mitigation is required. Conclusion The project would not conflict with local policies or ordinances protecting biological resources, and mitigation is not required. Issue 6: Adopted Conservation Plans Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? Issue 6 Impact Analysis The project is located within the Carlsbad HMP, and an HMP Permit from the City will be required. The project is consistent with the Carlsbad HMP because it has been sited within existing disturbed and developed land subject to regular maintenance and would only impact a very small (less than 0.1-acre) area of previously restored Diegan coastal sage scrub. Mitigation is provided for direct and indirect impacts consistent with the Carlsbad HMP, as discussed above. The mitigation included here is consistent with the PEIR for the 2012 CMWD Water Master Plans Update, which was found to be consistent with the Carlsbad HMP. No conflict with an adopted plan would occur. Mitigation Measures No mitigation is required. Conclusion The project would not conflict with any adopted plan, and mitigation is not required. Letter to Mr. Sean Diaz Page 19 of 25 March 30, 2022 FEDERAL CONFORMANCE ANALYSIS FOR BIOLOGICAL RESOURCES ISSUES Issue 1: Federal Endangered Species Act, Section 10 Does the project involve any direct effects from construction activities, or indirect effects such as growth inducement that may affect federally listed threatened or endangered species or their critical habitat that are known, or have a potential, to occur on site, in the surrounding area, or in the service area? The project site is situated mainly on developed land and does not overlap with any critical habitats. Therefore, the proposed action would not affect Critical Habitat. The project as proposed occurs approximately 140 feet from the occupied habitat for the federally-listed coastal California gnatcatcher. With the implementation of mitigation measures Bio-1D through Bio-1I, no impacts to breeding coastal California gnatcatcher would occur. Implementation of mitigation measure Bio-2A would mitigate for impacts to potential gnatcatcher habitat. With these mitigation measures, the project is consistent with the Carlsbad HMP and has incidental take coverage under the Carlsbad HMP. Further discussion is provided below regarding the potential effects of the proposed action on federally- listed species. Federally-Listed Plant Species. No federally-listed endangered (FE), threatened (FT), or candidate (FC) plant species are known or have the potential to occur in the vicinity of the project site; therefore, the project would not affect any federally-listed plant species. Federally-Listed Animal Species. In total, one FT animal species is known to occur in the vicinity of the project site (Appendix D): • Coastal California gnatcatcher; FT The project site supports marginal habitat for coastal California gnatcatcher, and a pair was observed within 500 feet of the project site. The project was carefully designed to avoid and minimize impacts on this species by developing the most disturbed area of the site, which is located across the street and approximately 140 feet away from the edge of the occupied habitat. The project may affect the coastal California gnatcatcher or suitable habitat for this species. Mitigation Measures The implementation of mitigation measures Bio-1D through Bio-1I and Bio-2A described above would ensure project consistency with the Carlsbad HMP. Coastal California gnatcatcher is a covered species under the Carlsbad HMP; therefore, the project would be in conformance with the ESA. Conclusion If unmitigated, project implementation may affect federally listed species; however, because the project was found to conform with the Carlsbad HMP, the project applicant has take authorization for incidental take of listed species as a third party beneficiary under the Endangered Species Act (ESA) Section 10 Permit issued to the City by the USFWS. Letter to Mr. Sean Diaz Page 20 of 25 March 30, 2022 Issue 2: Magnuson-Stevens Fishery Conservation and Management Act, Essential Fish Habitat Does the project involve any direct effects from construction activities, or indirect effects such as growth inducement that may adversely affect essential fish habitat? The project lacks marine resources and Essential Fish Habitat regulated under the Magnuson-Stevens Fishery Conservation and Management Act. No Essential Fish Habitat occurs in the immediate vicinity of the project site. Therefore, the project would not affect Essential Fish Habitat and would be in conformance with the Magnuson-Stevens Fishery Conservation and Management Act. Mitigation Measures No mitigation is required. Conclusion The project would have no direct or indirect effect on essential fish habitat, and no mitigation is required. Issue 3: Coastal Zone Management Act Is any portion of the project site located within the coastal zone? The project site is not located within the Coastal Zone. No coastal habitat occurs in the immediate vicinity of the project site. Therefore, the project would not affect any areas designated as Coastal Zone and would be in conformance with the Coastal Zone Management Act. Mitigation Measures No mitigation is required. Conclusion The project would have no direct or indirect effect on areas designated as Coastal Zone, and no mitigation is required. Issue 4: Migratory Bird Treaty Act Will the project affect protected migratory birds that are known, or have a potential, to occur on site, in the surrounding area, or in the service area? Project construction may result in the removal or trimming of vegetation during the general bird nesting season (January 15 through September 15), and, therefore, would have the potential to adversely affect nesting birds protected under the MBTA. Implementation of mitigation measures described above would ensure the appropriate pre-maintenance surveys and avoidance measures are completed to prevent adverse effects on nesting birds. Letter to Mr. Sean Diaz Page 21 of 25 March 30, 2022 Mitigation Measures The implementation of mitigation measures Bio-1D through Bio-1I described above would ensure project consistency with the protection of migratory birds; therefore, the project would be in conformance with the MBTA. Conclusion With the implementation of mitigation measures Bio-1D through Bio-1I described above, the project would result in no effect on migratory birds and would be in conformance with the MBTA. Issue 5: Protection of Wetlands Does any portion of the project boundaries contain areas that should be evaluated for wetland delineation or require a permit from the United States Army Corps of Engineers? No jurisdictional wetlands occur within the project vicinity. Therefore, the project would not affect wetlands and would not require a permit from the USACE. Mitigation Measures No mitigation is required. Conclusion The project would have no direct or indirect effect on areas subject to a permit from the USACE, and no mitigation is required. Issue 6: Wild and Scenic River Act Is any portion of the project located within a wild and scenic river? The proposed project is not planned on or in the immediate vicinity of areas designated as Wild and Scenic River. Therefore, the proposed project would not affect any areas designated as Wild and Scenic River and would be in conformance with the Wild and Scenic Rivers Act. Mitigation Measures No mitigation is required. Conclusion The project would have no direct or indirect effect on areas subject to the Wild and Scenic River Act, and no mitigation is required. CONCLUSION In conclusion, with the proposed mitigation the District’s planned maintenance activities would result in no impacts or less than significant impacts on special status plant species, sensitive natural Letter to Mr. Sean Diaz Page 22 of 25 March 30, 2022 communities/sensitive habitat types, federally protected wetlands and other waters, wildlife corridors and nursery sites, local policies and ordinances, and regional conservation plans. The project would be consistent with the Carlsbad HMP, which provides coverage for the coastal California gnatcatcher. The construction activities would further have no effect on federally listed plants, federally designated critical habitat, essential fish habitat, coastal resources, federally protected wetlands, and wild and scenic areas. The PEIR and Addendum did not list the Maerkle project as requiring biological mitigation; however, the incorporation of ground disturbance in the project makes some of the biological mitigation measures applicable to the project, as summarized here. This report satisfies PEIR mitigation measure Bio-1A, which requires project-level biological surveys for applicable CIP projects. Mitigation measure Bio-1B, which requires protocol-level surveys for special-status wildlife species, is not applicable to the project because the habitat to be impacted by the project consists of disturbed habitat and restored coastal sage scrub that is located in a thin strip between a paved road and a water tank. The restored coastal sage scrub is dominated by San Diego sunflower, making it a less preferred habitat for the coastal California gnatcatcher than the undisturbed coastal sagebrush-dominated coastal sage scrub located on hardline preserve lands to the south of the project site, which was found to be occupied. Mitigation measures Bio-1C and Bio-2B are not applicable to this project because this project is located within the Carlsbad HMP. Mitigation measures Bio-1D through Bio-1I and Bio-2A are applicable to the current project description and will be applied to this project. With the incorporation of mitigation measures Bio-1D through Bio-1I and Bio-2A, project impacts are mitigated to less than significant consistent with the PEIR, and no additional impacts or mitigation not discussed in the PEIR have been identified for the project.

Appendix B Cultural Resources Review – Maerkle Motorized Valves Project HELIX Environmental Planning, Inc. 7578 El Cajon Boulevard La Mesa, CA 91942 619.462.1515 tel 619.462.0552 fax www.helixepi.com June 24, 2022 01174.00005.003 Sean Diaz, PE, QSD Utilities Senior Engineer Carlsbad Municipal Water District 5950 El Camino Real Carlsbad, CA 92008-8802 Subject: Cultural Resources Project Site-Specific Review for the Carlsbad Municipal Water District Maerkle Motorized Valves Project Dear Mr. Diaz: HELIX Environmental Planning, Inc. (HELIX) was contracted to conduct a project site-specific review for the Carlsbad Municipal Water District (CMWD) Maerkle Motorized Valves Project (project), located in the City of Carlsbad (City), San Diego County, California. HELIX conducted a records search update at the South Coastal Information Center (SCIC), requested a Sacred Lands File search from the Native American Heritage Commission (NAHC), and conducted a review of historic topographic maps and aerial imagery. In summary, the project area is within a previously disturbed area and is not near a known cultural resource and no further cultural resources work is recommended. PROJECT LOCATION AND DESCRIPTION The project site is located south of State Route 78 and north of Agua Hedionda Creek, within an unsectioned portion of the Agua Hedionda land grant, in Township 12 South, Range 4 West on the San Luis Rey U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle (Figures 1 and 2, Regional Location and USGS Topography, respectively). The project site is located north of Lost Monos Canyon, adjacent to the Maerkle Reservoir (Figure 3, Aerial Photograph). The project involves the replacement of two existing isolation valves and piping with new motorized valves and piping, which would automate water system operations at this location. The existing 24-inch and 42-inch valves divert water into the 10-million-gallon tank and the 200-million-gallon reservoir. The new valves are to be installed in a new underground vault at the base of the slope to make it easier to access the valves and to improve worker safety. Facility improvements at the Maerkle Reservoir are included as Capital Improvement Program (CIP) project W-9 in the August 2019 Addendum to the City of Carlsbad Sewer Master Plan and Carlsbad Municipal Water District Water and Recycled Water Master Plans Update Program Environmental Letter to Mr. Sean Diaz Page 2 of 8 June 24, 2022 Impact Report (PEIR) (EIR 12-01; SCH No. 2012021006), as well as in the PEIR itself as Project R7. Per the PEIR’s Mitigation Monitoring and Reporting Program (MMRP), CIP projects proposed near a known cultural resource or projects that would result in ground-disturbing activities in a previously undisturbed area require a project-level cultural resources investigation. As outlined in Cul-1 in the MMRP, the cultural resources investigation includes this initial step: 1. A CIP project site-specific review of the records search data at the South Coastal Information Center shall be conducted to determine if the CIP project site has been subjected to a professional survey. a. If a current cultural resources report addressing potential impacts on cultural resources is available, the city or CMWD shall implement the mitigation measures provided within the report. In the event that a current and valid report is not available, or if the entirety of the CIP project site has not been professionally surveyed, then an updated records search shall be performed. b. In accordance with the 2017 Tribal, Cultural and Paleontological Guidelines, the City or CMWD shall contact the NAHC and local tribal governments for input on the project in order to identify any additional Native American resources that may not be included in the records search. REGULATORY FRAMEWORK Cultural resources are defined as buildings, sites, structures, or objects, each of which may have historical, architectural, archaeological, cultural, and/or scientific importance. The California Environmental Quality Act (CEQA), Public Resources Code (PRC) 21084.1, and California Code of Regulations (CCR) Title 14 Section 15064.5, address determining the significance of impacts to archaeological and historic resources and discuss significant cultural resources as “historical resources,” which are defined as: • resource(s) listed or determined eligible by the State Historical Resources Commission for listing in the California Register of Historical Resources (CRHR; 14 CCR Section 15064.5[a][1]) • resource(s) either listed in the National Register of Historic Places (NRHP) or in a “local register of historical resources” or identified as significant in a historical resource survey meeting the requirements of Section 5024.1(g) of the PRC, unless “the preponderance of evidence demonstrates that it is not historically or culturally significant” (14 CCR Section 15064.5[a][2]) • resources determined by the Lead Agency to meet the criteria for listing on the CRHR (14 CCR Section 15064.5[a][3]) For listing in the CRHR, a historical resource must be significant at the local, state, or national level under one or more of the following four criteria: 1. It is associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the United States; Letter to Mr. Sean Diaz Page 3 of 8 June 24, 2022 2. It is associated with the lives of persons important to local, California, or national history; 3. It embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of a master or possesses high artistic values; and/or 4. It has yielded or has the potential to yield information important to the prehistory or history of the local area, California, or the nation. Under 14 CCR Section 15064.5(a)(4), a resource may also be considered a “historical resource” for the purposes of CEQA at the discretion of the lead agency. Significant resources must retain enough of their historic character or appearance to be recognizable as historical resources and to convey the reasons for their significance. Resource integrity, which is the authenticity of a historical resource’s physical identity evidenced by the survival of characteristics that existed during the resource’s period of significance, is evaluated with regard to the retention of location, design, setting, materials, workmanship, feeling, and association. In an archaeological deposit, integrity is assessed with reference to the preservation of material constituents and their culturally and historically meaningful spatial relationships. A resource must also be judged with reference to the CRHR criteria under which it is proposed for eligibility. City of Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines In 1990, the City developed guidelines for the treatment of cultural resources. The guidelines were consistent with the cultural and historical resource guidelines set forth by the National Historic Preservation Act (NHPA), as amended, and CEQA, established standards of performance for resource investigation, and presented a systematic method of preserving identified resources. Carlsbad City Council Policy No. 83, adopted in 2016, called for the City to: “recognize [the City’s] responsibility to protect with improved certainty the important historical and cultural values of current Tribal Cultural Resources within the City limits and to establish an improved framework for the City's consultations with Native American Tribes that are traditionally and culturally affiliated with the City of Carlsbad, including the San Luis Rey Band of Mission Indians.” In 2017, updated Tribal, Cultural and Paleontological Guidelines were released to address the regulatory changes and the addition of new procedures to address additional requirements that had emerged since 1990 (ECORP 2017). The guidelines provide a framework for the roles and responsibilities of those responsible for compliance with the Guidelines and provide the processes by which cultural resources are assessed under the Guidelines. PROJECT SITE-SPECIFIC REVIEW METHODS HELIX conducted a record search of the project area and a half-mile radius at the SCIC on March 7, 2022. Reports of previous cultural resources studies and site forms for cultural resources were reviewed to determine previous survey coverage and to assess the existence of, or potential for, cultural resources to be present within the project area. Historic topographic maps and aerial imagery (NETR Online 2022) were reviewed to identify historic structures and land use in the area. In addition, modern aerial imagery was reviewed to assess the level disturbed within the project area. A pedestrian field survey was not conducted as part of this review. Letter to Mr. Sean Diaz Page 4 of 8 June 24, 2022 The NAHC was contacted for a Sacred Lands File search on March 10, 2022, to which the NAHC responded in a letter dated April 26, 2022. CMWD is currently conducting outreach to the Native American contacts identified by the NAHC. PROJECT SITE-SPECIFIC REVIEW RESULTS Records Search The records search indicated that 16 cultural resources studies have been conducted within the records search limits; of these, two overlap with the project area (Table 1, Previous Studies Within One-Half Mile of the Project Area). In general, the studies within half a mile of the project area include five cultural resource survey reports, three cultural resource studies, two testing reports, two cultural resource evaluations, two environmental documents, a cultural resource inventory, and a cultural resource investigation.

The cultural resource survey for the upgrade and expansion of the Squires Reservoir was conducted in 1988 by WESTEC Services, Inc. and included a records search and intensive cultural survey of a 3,000 linear foot pipeline, pump station, and buried tank near Squires Reservoir (Kyle and Gallegos 1988). The 1988 survey area encompassed the entirety of the current project area. A single isolated mano fragment was observed during the 1988 survey, though no site record appears to have been produce (Kyle and Gallegos 1988). As such, it is unknown if the isolate was located within the current project area; however, it was noted to have been observed in area containing plowed fields, which according to a review of aerial imagery from 1988 indicates the isolate was identified to the north of the project area. The records search resulted in the identification of ten cultural resources within the records search limits, all of which are located a quarter-mile or more from the project area (Table 2, Cultural Resources Recorded within One Half-Mile of the Project Area). In general, the resources include shell scatters, artifact scatters, milling areas, and the historic Rancho de los Quiotes to Mission San Luis Rey trail.

The NAHC further noted to contact the La Jolla Band of Luiseno Indians and the San Luis Rey Band of Mission Indians for additional information regarding the positive results. CMWD is currently conducting outreach to these two tribes identified by the NAHC. Historic Topographic Maps and Aerial Imagery No structures are visible within the project area on the 1893 and 1901 Oceanside (1:62,500), or 1901 San Luis Rey (1:125,000) topographic maps, though a trail is recorded north of the project area. This trail is not present on the 1948 San Luis Rey (1:62,500) map, though one is present to the west. Records indicate that the City started construction on the nearby Squires Dam in the early 1950s; by the time the 1968 topographic map was made, the Squires Dam had been finished and the adjacent Squires Reservoir—today called the Maerkle Reservoir—is shown on the map adjacent to Mount Hinton (O’Kelly, n.d.). Aerial photographs show the finished and filled reservoir; the 1964 aerial photograph shows the area graded, likely due to the construction of the reservoir and related infrastructure (NETR Online 2022). The area surrounding the Maerkle site was mass-graded prior to the 1990 aerial photograph in preparation for the expansion of the facility, which consisted of the construction of the buried tank, pumpstation, and additional pipelines; this photograph shows the completion of the tank just to the west of the reservoir (Figure 4, 1990 Aerial Photograph). Subsequent aerial photographs show the tank buried and covered in new vegetation (NETR Online 2022). Environmental Conditions Geologically, the project alignments are underlain by old tonalite dating to the middle Cretaceous (Kennedy and Tan 2007). The soil present within the project site consists entirely of Cieneba coarse sandy loam (5 to 15 percent slopes, eroded; Natural Resources Conservation Service 2017). This series consists of excessively drained, very shallow to shallow coarse sandy loams formed in material weathered from granitic rock (Bowman 1973). Letter to Mr. Sean Diaz Page 7 of 8 June 24, 2022 CONCLUSIONS AND RECOMMENDATIONS HELIX conducted a records search for the project area and a half-mile search radius, contacted the NAHC for a Sacred Lands File search, and conducted a review of historic topographic maps and aerial imagery. The record search indicated that a total of 16 studies had been conducted, and ten cultural resources had been recorded, within the half-mile search radius. One survey conducted in 1988 encompassed the project area and resulted in the identification of isolated mano fragment, likely to the north of the project area (Kyle and Gallegos 1988). No other cultural resources have recorded within or near the project area. The Sacred Lands File search were positive for the project vicinity; CMWD is currently conducting additional outreach related to the positive result. Per Cul-1 (2) in the PEIR MMRP, for those CIP project site(s) not addressed by a current cultural resources report (produced within five years of project proposal), a project-level Phase I Cultural Resources Survey shall be prepared in accordance with the 2017 Guidelines. While the cultural resources survey that encompassed the project area was conducted over 30 years ago, the review of aerial imagery undertaken as part of this review indicates that the entirety of the project area, as well as the area surrounding it, was rough graded in 1990 for the upgrade and expansion of the Maerkle Reservoir, which included an installation of a buried tank that is situated directly north of the project area (Figure 4). Additionally, the review of geologic and soil conditions for the project area do not indicate the presence of young alluvium soils within the project area, which typically contain a higher potential for buried cultural resources to be present. As such, it is likely the case that the grading that occurred in 1990 removed any potential for cultural resources to still be present within the project area. As the project area is within a previously disturbed area and is not near a known cultural resource, no further cultural resources work is recommended, including a project-level Phase I cultural resources survey or archaeological construction monitoring.

The results were positive. Please contact the La Jolla Band of Luiseno Indians and the San Luis Rey Band of Mission Indians on the attached list for information. Please note that tribes do not always record their sacred sites in the SLF, nor are they required to do so. A SLF search is not a substitute for consultation with tribes that are traditionally and culturally affiliated with a project’s geographic area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites, such as the appropriate regional California Historical Research Information System (CHRIS) archaeological Information Center for the presence of recorded archaeological sites. Attached is a list of Native American tribes who may also have knowledge of cultural resources in the project area. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. Please contact all of those listed; if they cannot supply information, they may recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call or email to ensure that the project information has been received. If you receive notification of change of addresses and phone numbers from tribes, please notify the NAHC. With your assistance, we can assure that our lists contain current information.
