This Public Works Technical Bulletin (PWTB) transmits current information on a variety of alternative methods to store stormwater and applicability of these methods to Army installations. The Assistant Chief of Staff for Installation Management requires that, in order to meet the “Gold” rating level, a rating tool called SPiRiT be used for all new construction on Army installations. SPiRiT was developed for the Army based on the concepts of Leadership in Energy and Engineering Design (LEED), which is a rating tool developed by the U.S. Green Building Council to encourage sustainable development. The Army is transitioning to the use of LEED guidelines in the near future (expected first quarter FY06). LEED and SPiRiT goals are not applicable to Civil Works projects at this time. Army regulations and policy addressing water quantity from development sites include 40 CFR 122.26, the Clean Water Act, and Army Regulation (AR) 200-1. Sustainable stormwater management is also required under Executive Order 13123, Greening the Government through Efficient Energy Management.
