Using the Bay-Friendly Landscape Standards to Implement Low Impact Development in the San Francisco Bay Area

摘要

Bay-Friendly Landscaping integrates Low Impact Design (LID), into a holistic, sustainable, watershed approach to landscaping that addresses current environmental, economic, health, and safety issues, including stormwater management and protection of San Francisco Bay water quality. More than 30 new landscapes, including libraries, community centers, fire stations, community colleges, multifamily housing and streetscapes, have been designed and constructed to meet the Bay-Friendly Landscape standards, with many of these projects also meeting both LID and LEED? goals. Project goals and features, including those to manage stormwater, are described for two Bay-Friendly Rated landscapes in the East Bay. Ohlone College's new campus in Newark, CA, for the Center of Health Sciences and Technology, designed to achieve the LEED? Platinum and the Bay-Friendly Ratings, includes weather-based irrigation controllers, planting with low level water requirements, an integrated pest management policy, a Bay-Friendly maintenance program, and multiple strategies to collect and filter stormwater. Sara Conner Court is a community of 57 affordable rental homes in Hayward, CA. The site directs all stormwater runoff toward lawns, planting beds and bioswales, moderates building temperatures and reduces heat island effect with effectively placed trees. Parking areas without curbs and grass-porous pavement in courtyards increase the infiltration and filtration of stormwater.
