Alternative Certification: Was the treatment system sizing and design reviewed by a qualified third- California Stormwater Quality Association (CASQA) released four Stormwater Best Management Practice Handbooks in January 2003. The design guidance contained in the New Development and Redevelopment Best Management Practice Handbook was also used in the preparation of this manual. Design specifications were also drawn from a number of other sources: D.3 Plants for Stormwater Measures Plants play an important role in the function of landscape-based stormwater treatment measures: Infiltration and evapotranspiration. Plants aid in the reduction of stormwater runoff by both increasing infiltration, and by returning water to the atmosphere through evapotranspiration. Pollutant trapping. discretionary approval is granted before 12/1/11, a NO answer means that stormwater treatment may be met through biotreatment; a YES answer means that stormwater treatment must be met through rainwater har vesting and reuse or infiltration.
