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

This report (December 2016), developed by the Chesapeake Bay Program Expert Panel, establishes methods for quantifying nutrient and sediment reductions from impervious surface disconnection practices. It refines crediting approaches for routing runoff to amended soils or treatment systems within conveyance networks, supporting consistent BMP definition, performance estimation, and verification under Chesapeake Bay Program accounting frameworks.
