<br />. <br /> <br />. <br /> <br />. <br /> <br />"IMPLEMENTATION OF STORMWATER DETENTION AT THE US AIR FORCE <br />'ACADEMY" <br /> <br />TOM KNOSTMAN, PROJECT ENGINEER, THE SEAR BROWN GROUP <br /> <br />The United States Air Force Academy, in a move to become a good neighbor in the Fountain Creek <br />Watershed, has undertaken program to retrofit the Academy for stonnwater detention. The Academy, <br />originally constructed in the 1950's, was built in a piedmont setting with little regard to stormwater <br />runoff. The Academy facilities consist of significant areas of impenneable surfaces perched on mesas <br />some three or four hundred feet above Monument Creek. The developments are connected to stonn <br />drainage systems which discharge to steep, ephemeral, piedmont stream channels. Significant erosion <br />and sediment release has occurred from these channels during the 50 years of Academy existence. <br />Sediments from the Academy flow to Monument and Fountain Creeks. <br /> <br />The Academy's detention program consists of regional detention ponds and channel improvement <br />measures to reduce the energy and thus sediment transport capacities of the stonnwater runoff. This <br />presentation: <br /> <br />. Explains the Academy's reasons for undertaking this program. <br /> <br />. Details one federal facility's approach to addressing stormwater and water quality concerns. <br /> <br />. Describes the Air Force Academy's community of "Users" and the process for approval. <br /> <br />. Describes the hydrology and hydraulic findings and the detention program. <br /> <br />. Show examples of the existing conditions. The Good... The Bad... and the Ugly! <br /> <br />. Show examples of finished projects and on going erosion mitigation. <br />
