Alameda County Low Impact Development Demonstration Garden

Location: Alameda Public Works Building, Hayward

Project Type:

PGAdesign was hired to re-design the landscape surrounding the Alameda County Public Works Agency building in Hayward to make a Low Impact Development (LID) demonstration garden.

The new landscape demonstrates different solutions to treat stormwater run-off, including biofiltration areas, flow-through planters, a modular suspended paving system for biofiltration, and a modular wetland system. The impermeable parking surface was converted to permeable asphalt and permeable pavers, and overhead solar panels were installed over much of the parking lot footprint.

The planting and irrigation plans represent best practices for water conservation and sustainability. The existing lawn was replaced with native planting and a 100% low-water-use plant palette supported by drip irrigation. It is WELO compliant and re-uses wood waste from tree trimming for mulching.

Certifications and Awards:

California Stormwater Quality Association (CASQA) Outstanding Best Management Practice Implementation Project, 2020
