Maggie Castro, Yuma County planning and zoning director, told a joint Yuma County Board of Supervisors and San Luis City Council work session that the county’s 2030 comprehensive plan — adopted by the Board of Supervisors in March 2023 — is intended to guide land‑use decisions, conserve resources and inform regulatory policy. "The purpose and effect of the comprehensive plan is primarily to aid the planning and zoning commission and the board of supervisors in the performance of their duties," Castro said during the presentation.

City officials described San Luis’s general plan, which the city said includes the 17 required elements for municipalities anticipating growth and covers a municipal planning area of roughly 92 square miles that includes lands that might be annexed in the future. Jose Guzman, identified in the presentation as the city’s director of development services, said the city recently completed two square miles of federal‑land annexation and is working with the state to pursue additional state land and county‑island annexations.

Supervisor Tony Reyes and other board members said faster interagency decision timelines would help developers and urged formalizing verbal understandings. "I think it would be a good idea to have some sort of memorandum of understanding," one council member said, recommending that informal agreements be documented so commitments survive elections and staff turnover.

Officials also discussed access to San Luis. Mayor Nieves Bridal and others said the city currently has two primary vehicle entrances and that a third access is a top objective to relieve chronic congestion on Cesar Chavez Boulevard and Highway 95. City and county staff said they will explore intergovernmental agreements to allocate right‑of‑way acquisition costs and coordinate infrastructure investments.

The session produced no formal motions or votes. Staff indicated follow‑up tasks: county and city planners will continue coordinating on annexation proposals, review possible memoranda of understanding and identify right‑of‑way needs for the proposed Avenue E‑D corridor.
