This project will eliminate the majority of runoff to the ASBS through the use of site design and structural BMPs. BMPs are the regrading and recontouring of the land within the project boundaries to direct storm flows away from the ASBS and the reduction of hardscape area to increase site permeability. The innovative site design includes curbed and tilted pathways, contoured swales and terraces built with retaining walls to contain sediments and push surface flows into structural and treatment control BMPs. The treatment control BMPs are vegetated areas where flows will infiltrate for plant use and be filtered through vegetation to remove nutrients and bacteria. Structural BMPs include catch basin filter inserts. The combination of BMPs should be adequate to treat all flows but major rain events. Smarttimers, water efficient sprinkler heads and drought tolerant vegetation will reduce or eliminate nuisance flows by reducing on-site water waste.
