The Western Washington Phase I and Phase II Municipal Stormwater Permits required Permittees to have programs to control runoff from new development, redevelopment, and construction sites. These programs are required to include a review of stormwater site plans for development activities. This training is intended to provide municipal staff whose primary function is to review plans for a general overview of how to review a plan set to ensure compliance with the Permits.
