LID Ordinances

The Low Impact Development (LID) ordinances cover new procedural requirements to consider early analysis of a site's hydrologic features, a requirement for LID. The ordinances also contain language to implement the LID Principles to minimize the loss of existing vegetation, minimize impervious surfaces, and minimize stormwater runoff. Finally, the new ordinances provide full support for LID Best Management Practices (BMPs), as defined in the City's NPDES Permit and the Department of Ecology Stormwater Management Manual for Western Washington by removing barriers to the implementation of these BMPs.
