NOW, THEREFORE, in consideration of the common interests and mutual benefits to be derived by the Participating Agencies, the Parties agree as follows.
Terms
1. Lead Agency. West Basin shall serve as the lead agency for implementing and managing the Project and holding and administering the consultant contract on behalf of the Parties. West Basin shall award a master contract to the selected consultant and shall manage the contract by authorizing task orders specific to the development of each Party’s UWMP once an authorized representative from the City has signed this cost share agreement and provided a copy to West Basin.

Each Participating Agency commits to designating a staƯ member to serve on the Project Management Team as the Party’s primary contact for the purpose of implementing the Project.
3. Consultant Selection Process. The Project Management Team jointly developed a scope of work for services that West Basin then published for competitive bids through a Request for Proposal (“RFP”) process. On August 15, 2025, West Basin received proposals from three potential consultants for the Project. During August 2025, interviews were conducted for the three potential consultants. On August 27, 2025, the review panel, made up of West Basin staƯ, unanimously selected Water Systems Consulting, Inc. (“Consultant”) as the highest-ranked firm based on the criteria defined in the RFP. On September 22, 2025, the West Basin Board of Cost Sharing Agreement for 2025 UWMP
Directors voted to authorize the West Basin General Manager to: (1) enter into an agreement with Water Systems Consulting, Inc. for the development of the West Basin and municipal retail agency UWMPs for an amount not-to-exceed $250,000; and (2) execute a cost share agreement with West Basin municipal customer retail agencies.
4. Project Cost. Consultant’s proposal contemplates providing services for West Basin and four (4) Participating Agencies. The cost of the Project shall not exceed $250,000. Any expenditures beyond this amount shall require prior written approval from West Basin.
5. Cost Sharing. The Parties agree to share the cost of the Consultant’s services to complete the work identified in the Scope of Work in Exhibit A. Total project costs shall be apportioned between West Basin and each Participating Agency. West Basin will be responsible for up to $100,000, and each of the four (4) remaining Participating Agencies will be individually responsible for $37,500. Should DWR decide to adopt any new requirements not specified in the Scope of Work after the 2025 UWMP Guidebook is released, Consultant shall incorporate new requirements into each of the Parties’ UWMPs. These requirements are not considered corrective work as described below.
6. Corrective Work. Should any of the UWMPs that are prepared and submitted to DWR be found lacking by DWR, the aƯected Party or Parties will work with West Basin to determine if the additional work required to finalize the UWMP(s) is the result of Consultant error. West Basin agrees to enforce the terms of the contract with Consultant, including the completion of corrective work, as needed. The Parties also agree that any corrective work required that is not the result of Consultant error is the responsibility of the individual Party. Parties may access the services of Consultant for corrective work under a separate agreement.

Scope of Services
Regional Urban Water Management Planning
INTRODUCTION & BACKGROUND
Urban Water Management Plans (UWMPs) are prepared by urban water suppliers every five years.
These plans support the suppliers’ long-term resource planning to ensure that adequate water supplies are available to meet existing and future water needs.
Within UWMPs, urban water suppliers must include an assessment of the reliability of water sources, description of demand management measures, a water shortage contingency plan and a discussion on the use of recycled water.
West Basin seeks to partner with the City of El Segundo, City of Inglewood, City of Lomita, and City of Manhattan Beach, collectively “Participating Agencies”, in order to satisfy all 2025 UWMP requirements. The project is expected to result in five (5) individual UWMPs; however, the district is not able to confirm the total until after proposals are evaluated. Therefore, the agency has the right to lower the number of individual UWMP’s. Participating Agencies seek to collaborate to increase coordination and maximize resource efficiencies.
West Basin will serve as the Lead Agency for implementing and managing the Project and holding and administering the consultant contract on behalf of the Participating Agencies. West Basin will award a master contract to the selected vendor and will manage the contract by authorizing task orders specific to the development of each Participating Agency’s UWMP.
The services should include a strategy to maximize collaboration amongst Participating Agencies throughout the Urban Water Management Planning Process. This should include recognizing requirements specific to wholesale and retail suppliers, identification of common resources, and an efficient approach to collecting information and producing required materials.
The proposed benchmark schedule for the development of the Participating Agencies’ 2025 UWMP update is as follows:
