Why Does My Site Need Certification?

Per the City of Spokane: "The Washington Department of Ecology issued the Eastern Washington Municipal Stormwater permit to the City of Spokane in order to protect water quality. The permit requires recurring inspections of structural Best Management Practices (BMPs) to ensure that adequate maintenance is being performed, and that the facility is functioning as designed. Structural BMPs include swales, bioretention cells, infiltration ponds, drywells, etc., each of which is considered a 'stormwater facility' ".

Municipal Code that cites this: Spokane Municipal Code Chapter 17D, Section 17D0.060.140.E.1 - Runoff and Infiltration Controls, requires the annual certification of private stormwater facilities. The municipal code was updated on December 2, 2021 following approval from City Council.
