Course Description:

Stormwater management requirements throughout the United States are being updated to require the reduction of stormwater runoff volumes and protection of downstream water quality through the use of structural control measures that infiltrate, harvest, evapotranspire and filter stormwater runoff. On new development projects these elements are most often integrated into the landscape design to minimize cost and to reduce the amount of dedicated land required for stormwater management. However, innovation is needed on retrofits and other projects with established drainage patterns or space constraints. This seminar will review the selection, design operation and maintenance of space efficient stormwater control measures including bioretention, subsurface infiltration, rainwater harvesting and media filtration. Material will be presented following a typical Low Impact Development based design hierarchy and LEED credits associated with each of these approaches will be discussed.
