Project Description

 710 Pier Ave., Hermosa Beach, CA 90254
At this popular community center’s front entrance, 2,500 sq. ft. of existing warm season turf was removed to create this Ocean Friendly Garden. The project was funded through a CA Proposition 50 IRWMP Grant administered by West Basin MWD and Surfrider Foundation, and supplemented by funding from California Water Service and the California Native Plant Society local chapter.  The project was completed in the Fall 2014.
A new ADA compliant, permeable gravel pathway and gathering space measuring approx. 600 q. ft. was installed, allowing visitors to walk into the previously inaccessible garden area. This pathway material was selected because it included a 2″ deep infiltration area (see the attached detail drawings) created by an engineered plastic matrix subsurface and therefore qualified as a permeable hardscape.
The site was contoured to capture rain from two main downspouts directed from 3,000 sq. ft. of roof from the adjacent building.  The rainwater flows through three main basins as it moves along the front of the building and slowly sinks back into the soil. The garden includes a diverse palette of 100% CA native plants and cultivars selected for their tolerance of salts and nutrients, since the site is irrigated with recycled water.
Turf area water requirement = 60,000 gallons per year
OFG water requirement = 25,000 gallons per year
