City of Washougal SMAP Plan Washougal, Washington

The City of Washougal is advancing its commitment to protecting its natural environment and charting a clear path to implementing stormwater improvements in the Gibbons Creek Watershed. A Storm Stormwater Management Action Plan (SMAP) was developed to help meet those commitments as well as the City of Washougal’s NPDES Phase II permit requirements. In continuing this long-lasting relationship with the city, Otak also regularly assists with best practices for developing their GIS program for effective data infrastructure development, collection, and display to the community and internal staff.

Protecting a Watershed with a Stormwater Management Action Plan

The City of Washougal’s SMAP Plan for Gibbons Creek aims to help the City maintain compliance with its Phase II municipal stormwater permit and other surface water and groundwater quality regulations. In developing the action plan, GIS analysis was utilized along with data collected from the city. This included field visits to assess all receiving waters in the city limits and prioritizing a basin for stormwater retrofits. Utilizing GIS web mapping applications, this work also delivered effective communications for agency collaboration and public outreach on project progress.
