Urban development traditionally involves replacing natural landscapes with impermeable pavements and storm drain systems, or “gray” infrastructure.  Green Infrastructure (GI), otherwise known as Green Stormwater Infrastructure uses vegetation, soils, and other elements and practices to capture, infiltrate, treat, and slow urban runoff.

The Alameda County Public Works Agency has converted two agency-owned parking lots at 951 Turner Court in Hayward, CA into a GI demonstration project area. Completed in spring of 2019, the site consists of 14 GI features, each described in detail on interpretive panels and integrated into a self-guided tour, open to the public. Training workshops for professionals in stormwater management, landscape architecture, construction, and maintenance are held on site. This site is a Bay-Friendly Rated Landscape.

The project is a collaboration of the Public Works Agency and the Alameda County Flood Control & Water Conservation District, with funding provided in part by the California State Water Resources Control Board.
