Napa State Hospital Solar Project
Document Type
MND - Mitigated Negative Declaration
Document Description
The proposed project is a solar PV power generation system to be located on approx 12.95 acres of land at the address of 2100 Napa Valley Hwy, Napa, CA 94558, which is part of a larger state-owned facility. The ground-mounted solar array would convert sunlight to direct current electrical power which would then be converted to alternating current by string inverters before being delivered to the PG&E distribution system. The total system size is expected to be approx 1.08 mw, subject to final design and site optimization. The solar system would be configured into three generally contiguous arrays that are designed to avoid impacts to on-site jurisdictional water and other natural resource features identified during on-site environmental surveys. A security fence would be installed around the solar arrays. The fence would consist of chain-link with a min 6-ft height topped with three strands of barbed wire per applicable electrical and safety code requirements. The solar system will utilize either fixed-tilt or single-axis tracking mounting technology to optimize efficiency and performance. Single-axis trackers are designed to rotate the arrays in the east-to-west plane to track the sun's movement across the horizon. The ground-mounted arrays would be supported on driven pipe piles, driven H-piles, or reinforced concrete cast-in-drilled-hole piers, with the foundation design to be finalized following completion of on-site geotechnical surveys. Once installed, the ground-mounted solar arrays would be approx 8 ft in height depending on the time of day to the extent a tracking system is utilized.
