Green Stormwater Solutions for Silverdale
To protect Dyes Inlet shellfish and keep our water
safe for swimming and wading, Kitsap County studied options for
improving Silverdale’s stormwater infrastructure. This study helped
identify and prioritize potential locations to integrate stormwater
retrofits on public property, in
right-of-way, and on private property.
These “green” stormwater solutions, sometimes called low impact
development (LID), include rain gardens (bioretention) and pervious
pavement. Green infrastructure uses natural features to keep stormwater
runoff close to its source. By keeping water on site, green
infrastructure reduces flooding, removes pollutants, and replenishes our
ground water.
It can also be used to add green spaces to the
neighborhood features, such as sidewalks, trails, and public open space.
The Silverdale LID Retrofit Plan was completed in January 2013. Prior to
completion of the plan the highest priority opportunity sites were moved
forward into design and construction planning. These sites are the
Duwe’iq Wetland Treatment Facility, the Silverdale Way Water Quality
(WQ) Treatment Planter Boxes, and the Ridgetop Median Green Streets.
Ecology grant funding was awarded for partial funding of the Silverdale
Way WQ Treatment Planter Boxes and County funding was used to purchase
property for the Duwe’iq Wetland Treatment Facility. In 2012 the County
applied for partial Ecology grant funding for the Ridgetop Median Green
Streets. It is anticipated to complete construction of these three high
priority projects by 2016 and will result in stormwater treatment of
approximately 40 acres of road runoff currently receiving little or no
pollution removal.
