The Engineering Division reviews development projects for compliance with City stormwater requirements.  These requirements are intended to ensure that the construction of a project and the resulting developed site do not create flooding or erosion impacts to public or private property and do not negatively affect the quality of surface water bodies.  The most recent code revision was in 2010.  This revision update included changes to ensure compliance with the Western Washington Phase II Municipal Stormwater Permit, issued by the Department of Ecology.  The following resources may be helpful when designing your development project. 
 
Edmonds Community Development Code (ECDC) - ECDC 18.30 is the stormwater chapter of the development code.  The requirements of the chapter are minimum requirements.  Compliance with all applicable federal, state and local laws and regulations is still required.
