Overview
The Springbrook Creek Wetland & Habitat Mitigation Bank Project enhances 110 acres of wetlands and buffer, restore and create a larger connected 20 acres of wetland; totaling approximately 130 acres of wetlands. Thousands of native plants were planted over the entire project site; including black cottonwood, pacific willow, sitka spruce, western red cedar, snowberry, douglas-fir and big-leaf maple. These trees, shrubs and plants will attract and create habitat for many different species of wildlife. WSDOT crews have completed building an interpretive boardwalk trail through a portion of the site that will provide opportunities to educate the public on the benefits of wetlands and the habitat they support. The start of the boardwalk trail is located on SW 27th Street between Oakesdale Avenue SW and Lind Avenue SW.

How You Benefit
Car GlyphRelieves Congestion
Springbrook Creek Wetland and Habitat Mitigation Bank is an early environmental investment (EEI) project. The Bank provides mitigation for highway construction and city development projects prior to impacts on wetlands and other aquatic resources.
Leaf Glyph Protects Environment
The Springbrook Wetland and Habitat Mitigation bank benefits the environment and transportation projects by:

Increasing habitat diversity and developing habitat conditions.

Potentially improving water quality and enhancing hydrologic function.

Removing wetland fills.

Improving riparian (strip of land adjacent to a body of water) functions in a highly urbanized area.

Setting up the site in advance of project development and wetland impacts.

Consolidating mitigation for multiple small wetland impacts into one large site with greater ecological value - the value of the site increases as the site matures.

Partnerships & Cooperation
WSDOT and the City of Renton launched an innovative partnership to re-establish and enhance approximately 130 acres of land in the Renton area, addressing the effects of development within the city and from WSDOT transportation projects.
