2026-02-26 IID-LQ Avenue 58 Substation - Engineering & Procurement AgrENGINEERING AND PROCUREMENT AGREEMENT This ENGINEERING AND PROCUREMENT AGREEMENT ("Agreement") is made and entered into this 26 day of February, 2026 , by and between City of La Quinta, an incorporated city in the County of Riverside, State of California ("City") and Imperial Irrigation District, an irrigation and electric district organized and existing under the laws of the State of California, ("IID"). City and IID each may be referred to individually as a "Party," or collectively as the "Parties." RECITALS WHEREAS, for purposes of City's participation in and execution of this Agreement, California law has long recognized and authorized the production, generation, transmission, and furnishing of (among other utilities) electric power for use by the public. (See, e.g., Cal. Const., Art. XI, § 9(a) [municipal corporations may establish, purchase, and operate public works to furnish its inhabitants with (among other utilities) electric power]; id., Art. XII, § 3 [Public Utilities Commission may regulate private providers of electric power].) Likewise, California law has long recognized and authorized the ability for public agencies not only to charge users of electric power for improvements and services from that utility but also to use public funds in furtherance of providing electric power as a utility. (See, e.g., Independent Energy Producers Assn., Inc. v. State Bd. of Equalization (2004) 125 Cal.App.4th 425, 443 [electric power facilities constructed with assistance of public funds].); WHEREAS, the La Quinta Financing Authority, a public body corporate and politic ("Financing Authority") and the City have entered into that certain Financing Agreement, dated of or about even date as this Agreement, for purposes of funding related to this Agreement. As such, all references herein to "City" shall refer to the City and/or the Financing Authority, as appropriate; WHEREAS, IID is the electric service provider within a defined service territory area within Imperial County, California and portions of Riverside County, California ("District Service Area"); WHEREAS, City seeks to facilitate new growth and development opportunities within the City's boundary and sphere of influence, specifically those located within the general vicinity of IID's Avenue 58 Substation ("Avenue 58 Facility"); WHEREAS, to facilitate new electrical service to the Developments, IID has evaluated the possibility of adding to the Avenue 58 Facility certain additional electrical distribution facilities namely the installation of one (1) new 50MVA transformer, ancillary substation equipment and new corresponding distribution line extensions (getaways' conduit system) up to the perimeter fence of the Avenue 58 Facility located immediately north of Avenue 58 in the City of La Quinta (collectively, the "New Facility"), a schematic representation of which is shown on Attachment "C", attached hereto and by reference incorporated herein; WHEREAS, the Avenue 58 Facility is designed and operated primarily to support IID's regional transmission network (commonly referred to as "BES") and offers limited physical space to accommodate the New Facility in a manner which would permit any future physical or legal separation of such New Facility from the Avenue 58 Facility such that IID may operate the Avenue 58 Facility separate and apart from the New Facility in compliance with its legal and regulatory obligations arising out of its operation of the BES within its Balancing Authority Area ("BAA"); WHEREAS, IID, City and certain land developers with projects located within the vicinity of the Avenue 58 Facility (each, a "Developer" and collectively, the "Developers") are negotiating a final form of agreement concerning the Developers' collective funding of the New Facility and their respective rights to certain capacity therein once the New Facility is constructed as set forth in said agreement (the "Funding and Reservation Agreement"); WHEREAS, because certain components of the New Facility require significant lead-time for manufacturing prior to delivery and installation, City has requested IID conduct the initial engineering and procurement of the long lead-time items necessary for the construction of the New Facility and to undertake those preliminary activities necessary for development of the New Facility; WHEREAS, City has agreed to advance funds, subject to reimbursement by Developers pursuant to the terms set forth in the Funding and Reservation Agreement; necessary for IID's procurement of the long lead-time items and preliminary engineering activities necessary for the development of the New Facility as set forth in this Agreement; WHEREAS, the Parties acknowledge that the New Facility will be owned, operated and maintained by IID as an integral part of the Avenue 58 Facility and which New Facility shall not be subject to any physical or legal separation therefrom the Avenue 58 Facility under any circumstances and that City shall not seek or otherwise advocate for in any proceeding, whether legislative or legal, for the legal or physical severance of the New Facility from the Avenue 58 Facility; and WHEREAS, the Parties wish to set forth their agreement with respect to the initial engineering and procurement as described above. NOW, THEREFORE, in consideration of and subject to the mutual covenants contained herein, including the foregoing which are part of this Agreement and not mere recitals, the Parties agree as follows: 1. Capitalized Terms. Unless specifically defined herein, capitalized terms shall have the meanings indicated in IID's Regulations or Developer Energy Planning Guide. 2. Authorization of Work. City authorizes IID to perform the preliminary engineering and procurement (the "Work") more specifically described in Attachment A. 3. Responsibilities of IID. IID shall: a. Perform the preliminary engineering activities described in Attachment A; b. Order and procure the long lead-time equipment necessary for the development of the New Facility, including a 50MVA Transformer, breakers, switches, relays and such other equipment or products as IID may determine in its sole discretion to be a risk of impacting schedule due to long lead-time, as the same are generally described in Attachment A. IID shall cause the procurement, design, including engineering, construction, operation, maintenance and repair of the New Facility to comply with all applicable federal, State and local laws, ordinances, rules, regulations, orders and policies relating to the New Facility ("Applicable Laws") and any applicable IID requirements, practices and standards, including all IID plans and specifications required for the procurement, design, engineering, construction, operation, maintenance and repair of the new Facility ("IID Plans and Specifications"); c. Own, operate and maintain, as part of its electrical system, at all times, in accordance with good utility practice, all portions of the New Facility, including all equipment, products and other materials necessary for the construction of the New Facility, including that which may be acquired pursuant to this Agreement; d. Use all funds provided by the City under this Agreement only for the purchase of the equipment identified in Attachment A. Upon written request from the City, IID shall deliver within thirty (30) days to City an accounting for all Work completed or to be completed pursuant to this Agreement and for any funds received in connection with this Agreement, including line - items for payments made or services rendered. If any funds remain unspent after full performance by IID of its obligations under this Agreement, or are unable to be spent for any of the authorized purposes set forth in this Agreement (such as, for example, the equipment is no longer able to be delivered to IID for reasons outside of the control of any of the Parties to this Agreement), then IID shall return said unspent or unused funds to the City within thirty (30) days after either IlD's full performance under this Agreement with funds still remaining, or any third party vendor or other independent person/entity notifies IID or City that said funds are no longer able to be used for the purpose(s) set forth in this Agreement; e. Expend the funds provided by City to IID, within ninety (90) days of the receipt of such funds by IID. Any funds not expended within ninety (90) days shall be returned to the City. 4. Responsibilities of the City. City shall: a. Pay, in advance, the estimated costs to be incurred by IID associated with the review and approval of activities identified in this Agreement, as specified in Attachment A. The amount of a deposit of such costs is attached hereto as Attachment B and is due to IID upon execution of this Agreement (the "Required Deposit"); and b. Cooperate with IID in meeting the obligations set forth in Section 3, including but not limited to, providing information to IID necessary for the development of the New Facility. 5. Failure of City to Meet Obligations under this Agreement. If City fails to meet its obligations under this Agreement, the following terms apply: a. IID may provide to City a notice to cure and correct. Thereafter, City shall have thirty (30) days within which to meet its obligation(s) as listed in the notice to cure and correct. If City fails to meet its obligation by the end of that thirty (30) day period, IID may cease all activities or efforts under this Agreement related to the Work, and may at its sole discretion, terminate this Agreement upon written termination notice, if City fails to adhere to its obligations as set forth herein. b. If for any reason City fails to make a payment to IID as required by this Agreement, IID will notify City of such failure. If City does not make the required payment within thirty (30) calendar days of the notice of failure to make timely payment, IID may, in its sole discretion, immediately terminate this Agreement and seek reimbursement of any deposit(s) then remitted by IID to any service provider or equipment manufacturer with respect to the New Facility. To the extent IID is successful in obtaining any reimbursement of all or any portion of any deposit(s), IID may first apply therefrom said sums, in the following order: (1) to satisfy any outstanding financial sums owing under any contract to which IID has entered into pursuant to this Agreement to facilitate the development and construction of the New Facility; then (2) to satisfy any sums outstanding hereunder this Agreement owed to IID for any portion of the Work completed hereunder, including, for example, any engineering work or study, prior to such termination; and then, (3) to City. 6. Failure of IID to Meet Obligations under this Agreement. If IID fails to meet its obligations under this Agreement, the following terms apply: City may provide to IID a notice to cure and correct. Thereafter, IID shall have thirty (30) days within which to meet its obligation(s) as listed in the notice to cure and correct. If IID fails to meet its obligation by the end of that thirty (30) day period, City may cease all activities or efforts under this Agreement and may, at its sole discretion, terminate this Agreement upon written termination notice, if IID: (i) fails to use any of the funds from the City for the purchase of the equipment identified in Attachment A and IID's review and approval of activities arising from the integration and use of the equipment identified in Attachment A, or (ii) fails to adhere to its obligations as set forth herein. 7. Intention to Execute Funding and Reservation Agreement; Intent of the Parties. IID and City intend to enter into the Funding and Reservation Agreement (together with Developers) with respect to the ultimate funding, construction, and operation of the New Facility. The Funding and Reservation Agreement will identify the totality of the facilities and costs necessary for the complete construction of the New Facility and any engineering, design, and procurement activities identified as necessary for the New Facility. The Funding and Reservation Agreement will also account for Work already undertaken and payments already made pursuant to this Agreement together with provisions for reimbursement to City by Developers. The Parties further acknowledge that the City, if the City is not reimbursed through the Funding and Reservation Agreement, intends to be reimbursed through a potential combination of means including: other potential negotiated agreement(s) with developers of future projects in City before those developers receive power; payment of a development impact fee to the City as a condition of regulatory approval for a future development project when the project receives power from the New Facility which is funded under this Agreement; or payment to the City pursuant to any other lawful means. Notwithstanding the foregoing, City and IID expect that City will be fully reimbursed for all payments made by City pursuant to this Agreement from the first milestone payment to be paid to IID by the Developers under the Funding and Reservation Agreement and that the foregoing mechanisms by which City may seek reimbursement shall be absolutely conditioned on the failure of City to be reimbursed in full for all payments made under this Agreement from the first milestone payment to be paid to IID by Developers under the Funding and Reservation Agreement. 8. IID Not Liable for Delays. In no event shall IID be responsible under the terms of this Agreement for any delay in completion of the Work, provided, however, IID will make all commercially reasonable efforts to avoid delay in completion of the Work. 9. Other Fees and Charges. Nothing in this Agreement compels any public entity to issue any permit, approval, or entitlement that otherwise must be applied for and processed in accordance with applicable laws and procedures, including any discretionary or ministerial permits. Nothing in this Agreement constitutes a waiver of any applicable fees, assessments, or taxes. 10. Termination of Agreement. Subject to Section 11 below, this Agreement shall terminate upon the earliest of the following to occur: (i) written notice provided by IID to City as permitted herein; or (ii) written notice provided by City to IID as permitted herein. 11. Survival of Obligation to Pay and Reconciliation. Except in the situation of IID's default, City's obligations to pay IID for costs incurred or committed to be incurred pursuant to this Agreement will survive termination of this Agreement for any reason except insofar as payment of such costs is provided for in the Funding and Reservation Agreement. 12. Ownership. City acknowledges and agrees that IID solely shall own the New Facility, including all appurtenant equipment, rights, and associated interests made, given, granted or arising in connection therewith, including any manufacturer's warranties upon any of the foregoing, including any which may be acquired pursuant to this Agreement. In accordance with the recitals contained hereinabove, City acknowledges that at all times hereafter the date of this Agreement, the New Facility will be owned, operated and maintained by IID as an integral part of the Avenue 58 Facility and which New Facility shall not be subject to any physical or legal separation therefrom the Avenue 58 Facility under any circumstance and that City shall not seek or otherwise advocate for in any proceeding, whether legislative or legal, for the legal or physical severance of the New Facility from the Avenue 58 Facility. Upon completion of the New Facility, IID shall operate and maintain the New Facility as part of its electric system in accordance with good utility practice. City shall not acquire any ownership rights in the Avenue 58 Facility or the New Facility by virtue of this Agreement. 13. Indemnification. The City, nor its Council, officers, executives, directors, employees, contractors, agents or representatives thereof shall not be responsible for any damage or liability occurring by reason of any act or omission of IID under or in connection with the Work performed by IID under this Agreement. Pursuant to Government Code Section 895.4, IID shall fully indemnify and hold City harmless from any liability imposed for injury (as defined by Government Code Section 810.8) occurring by reason of any act or omission of IID under or in connection with the Work performed by IID pursuant to this Agreement. Likewise, neither IID nor its Board, or any officer, executive, director, executive, employee, contractor, agent or representatives thereof shall be responsible for any damage or liability occurring by reason of any act or omission of City under or in connection with this Agreement, and pursuant to Government Code Section 895.4, City shall fully indemnify and hold IID harmless from any liability imposed for injury (as defined by Government Code Section 810.8) occurring by reason of any act or omission of City under or in connection with this Agreement. 14.
