An exclusive, highly regarded elementary, middle and secondary school in the Sherman Oaks neighborhood of the City of Los Angeles, California, has constructed two new buildings on campus, including a new Science and Academic building. City of Los Angeles Best Management Practices (BMP) required the detention of over 23,000 gallons of stormwater run-off attributable to the new buildings. The School, in conjunction with KPFF Consulting Engineers, developed an irrigation re-use plan for the detained stormwater to save on-site water resources and advance their sustainability goals.
Two separate RainSpace Stormwater Detention Chambers were installed on campus: one under a parking area adjacent to an academic building and the other under a sidewalk and sloping landscape area. Each RainSpace Stormwater Detention Chamber inlet utilized a CDS stormwater clarifier. After each excavation was completed, the two complete RainSpace Stormwater Detention Chambers were installed in the equivalent of two working days by a crew of four persons, expending a total of 63 labor hours. The installing contractor was George Kaufman Plumbing, Arcadia, Ca. The general contractor was Hathaway Dinwiddie, Los Angeles, Ca. Engineering by KPFF Consulting Engineers, Los Angeles, Ca. Permitting and inspection was through the Los Angeles Building and Safety Department and the Health Department.
