Eastern washington low impact development guidance manual

Eastern Washington Manual • Eastern Washington permittees are developing an Eastern Washington LID guidance manual funded by an Ecology grant. • The Stormwater Management Manual for Eastern Washington will be updated during the permit term, in part to include LID BMPs and guidance from the Eastern Washington LID Manual. • The . Low Impact Development (LID) for Nursery and Landscape Professionals Stormwater is regulated under the federal Clean Water Act administered in Washington State by the Department of Ecology. Under Department of Ecology’s direction, cities and counties are required to integrate Low Impact Development (LID) into their local development and re-development . Low Impact Development (LID) is a stormwater management approach that uses a suite of hydrologic controls (structural and non-structural) distributed throughout the site and integrated as a treatment train (i.e., in series) to replicate the natural hydrologic functioning of the landscape.
