Policy 9040 and compliance The following section will highlight those areas that have been designed into the new high school that comply with the Boazd's policy for high performance schools, Each is simply meant to be an overview and more detail is available upon request. It should be noted that these features have already been designed iztto the building and are not add ons to the program. Alternative Transportation ® Provides bicycle racks and shower facilities for use by 10% of occupants Storm water Management - Peal< Discharge Rate and Voltune o Provides storm water detention via temporary storage inbio-retention areas and constructed wetlands to ensure the post-development peak runoff rate does not exceed the pre-development rate ® Provides storm water retention and re-use via temporary storage in constructed wetlands and re-use as irrigation water on athletic fields to ensure the post-development peak runoff volume does not exceed the pre-development volturze Storm water Management -Water Quality ® Provides storm water management system to remove total suspended solids (TSS) and total nitrogen (TN) from storm water rtmoft generated by the first inch of rainfall through utilization of constructed wetlands, bio-retention areas, open channel practices, re-use and other methods Special Rain Collection System ® A rainwater collection system is being used to capture rainwater from the roof to reduce the amount of potable water needed for water closet and urinal flushing, make-up water for the cooling towers and athletic field irrigation, A 100,000 gallon cistern will collect filtered rainwater from the 120,000 square feet of roof. The water will then be pumped back into the building for reuse, The cistern is being sized larger than needed to allow for periods of drought. Over 1,200,000 gallons of rainwater will be reused each year, This is 1,200,000 gallons less of potable water use. This also reduces the impervious area of the site by approximately 15% although the reduction is not allowed in the approval process. For comparison purposes, this reduction in impervious surface is equal to 450 parking spaces, A further comparison shows that providing compact parking spaces for 40% of the parking areas would only reduce impervious area by less than 1%, Site Disturbance and Use ® The development footprint has been reduced to preserve a minimum of 30% of the site in undeveloped space and maintain natural buffers along streams, floodplains and wetlands
