The Capital Facilities Program The Capital Facilities Program prioritizes and manages large stormwater system improvement projects. These projects reduce the frequency and severity of flooding, improve water quality, increase fish passage and provide habitat.

Retrofits Some of the older parts of the stormwater system do not remove pollutants or control storm flows well, causing problems downstream. We identify and focus on locations with these issues for community stormwater retrofits. These projects upgrade the system with new structures. Some use green stormwater techniques, like rain gardens, permeable pavement, sand filters or tree filter boxes that mimic the natural processes that were in place before the site was developed.
The County maintains many stormwater ponds and ditches, which are crucial to the system. When we retrofit stormwater facilities and the drainage system, we improve water quality treatment, reduce flooding, and add more lifespan to these systems. Stormwater staff perform these projects, which are not large enough to warrant outside contractors.

to develop a Stormwater Management Program (SWMP) that includes all the required activities, implement
those activities within the required timeframes of the Permit term, and submit annual reports to the
Washington State Department of Ecology each year to document progress toward completing program
implementation.
