Impervious Disconnection to Amended Soils BMP Expert Panel Report
Recommendations of the Expert Panel to define removal rates for disconnecting runoff from impervious areas onto amended soils or treatment in the stormwater conveyance system.
Description
The Urban Stormwater Workgroup convened an Expert Panel to define and develop nutrient and sediment load reduction recommendations using the disconnection of existing impervious area runoff from stormwater drainage systems as new best management practices (BMP) to be adopted by the Chesapeake Bay Program (CBP). Disconnection of impervious area runoff is not currently defined by the CBP as a BMP available for credit towards Watershed Implementation Plans. The Expert Panel provided representation from the Bay jurisdictions, scientists, and stormwater practitioners to review and evaluate the scientific literature and other data sources, review the Chesapeake Bay Watershed Model assumptions to simulate the impact of impervious area disconnection and make recommendations to quantify and qualify this BMP, as well as review information to verify its performance after implementation. These recommendations are outlined in this report.
