Address: 853 Lake Washington Blvd

Current Status

Project Description

Budget: $450,000
This creek daylighting project will cost approximately $450,000 and is being funded by grants and private donations.
Construction begins: March 2007 - December 2007
Project complete: First Phase - 2007

Project: This community-initiated project is taking Madrona Creek out of pipes from midway up the ravine, and running the water on the surface in a new creek bed. The sloping lawn area between Lake Washington Boulevard and Lake Washington will be replaced with native plantings. The project includes:

• Construction of a new creek channel where water is currently piped, from midway up the ravine, under Lake Washington Boulevard, and down the slope to the Lake Washington shoreline.
• A 4,800-square-foot wetland cove will replace the existing lawn area.
• Installation of new fish-freindly road culverts under Lake Washington Blvd.
• A crushed rock pedestrian trail along the lakeshore and around the wetland cove.
• Two new creek crossing bridges, one below the boulevard and one in the ravine.
• Re-vegetation of approximately 1.5 acres of existing park with native plants, including in the ravine and along the lakeshore.
• Maintenance of views to the lake in three key view corridors through plantings three to four feet in height.

Anticipated Impacts:
Park access will be limited at times during construction and there will be truck traffic, equipment noise, and traffic modifications during construction.
