AI Contract Overview

Mariposa County plans to develop a transit yard on a 1.54-acre site east of State Route 49, featuring a solar canopy and electric vehicle charging infrastructure to support zero-emission vehicle operations. The solar canopy, elevated approximately 14 feet above ground, will cover paved areas to provide shelter for vehicles while maintaining access and operational space beneath. Photovoltaic panels mounted on the canopy will generate electricity, which will be stored in on-site batteries and used to power EV charging stations and other facility needs, with design flexibility to accommodate future expansion of the zero-emission fleet. The project includes essential electrical systems such as conduits and connections to route solar-generated power efficiently, ensuring reliable energy delivery for daily operations. In addition to the solar and charging components, the project will introduce a new driveway connecting to Frank Wilson Road and install storm drain facilities to manage runoff and meet environmental standards. The site will serve as a dedicated transit yard for the County’s vehicle fleet, enhancing sustainability and reducing reliance on fossil fuels. The initiative is part of broader efforts to modernize public infrastructure and align with clean energy goals. Primary contact for inquiries is Matiel Holloway, Senior Civil Engineer, with project management support from Tsui Li of FCS International. The opportunity was posted on June 18, 2026, and is located in the 95338 zip code area of California.

Full Description

Show more
The Mariposa County Public Works Department proposes to construct a transit yard featuring a solar canopy and electric vehicle (EV) charging stations on the 1.54-acre project site, located east of SR- 49. The charging infrastructure would be designed to accommodate the operational needs of the County and would allow for future expansion of Zero-Emission Vehicles (ZEVs). The project includes the installation of a solar canopy consisting of elevated structures designed to support photovoltaic (PV) panels mounted above paved surfaces. The canopy would be approximately 14 feet high and configured to provide overhead coverage for vehicles while allowing circulation, parking, and operational use of the underlying areas. Electrical equipment such as conduits and connections would be installed to convey electricity generated by the PV panels to on-site electrical systems. The project would include batteries for power storage. The electricity generated by the solar canopies would support on-site operations, including EV charging and other facility energy demands. Includes a new driveway connecting to Frank Wilson Road, and new storm drain facilities.
