About Stormwater Planting

Native plants play an important role in stormwater management. Kitsap Conservation District has supplied planting designs and native plants to the Kitsap County Public Works Stormwater Division since 2011 as they move toward more natural stormwater treatment.

Duwe’iq Regional Stormwater Wetland Facility

Kitsap Conservation District arranged for local nurseries to grow and supply the approximately 36,000 native emergents, trees and shrubs, which are integral to the function of this project. KCD supervised the planting in the fall of 2016 and has provided ongoing maintenance since that time. The Duwe’iq constructed wetland treats runoff from approximately 15 acres of paving and rooftop in Silverdale. Up to 90% of harmful metals, solids and oils are removed before flowing into Dyes Inlet, through contact with soils and plants in a series of treatment ponds. Upland planting areas provide habitat for a variety of birds.

Naturalized Storm Ponds

Since 2012, Kitsap Conservation District has worked with Kitsap Public Works Stormwater Division to produce planting plans, and source native plants for approximately sixty storm pond naturalization projects. Naturalization replaces the grass commonly seen in storm ponds with a varied planting of native wetland plants, groundcovers and shrubs. Naturalizing ponds with native plants reduces erosion, filters pollutants, improves habitat and reduces maintenance costs.

County site project description.

Whispering Firs Stormwater Park

Kitsap Conservation District procured and supervised the planting of over 7,000 native and ornamental plants in this new regional stormwater facility along Silverdale Way. This facility will manage and treat runoff from approximately 115 acres of surrounding development before it flows into Clear Creek. Whispering Firs includes walking trails, a picnic area and open grass field.

Green Streets and Enhanced Ditches

Since 2011, Kitsap Conservation District has worked with Kitsap County Public Works to plant approximately twenty Green Streets and Enhanced Ditches throughout the county. Green Streets and Enhanced Ditches are a more natural way of reducing stormwater flow and removing pollutants from road runoff by incorporating amended soils and native plants that soak up and filter pollutants. They can be a neighborhood amenity by promoting walkability, improving air quality, and providing habitat.
