DESCRIPTION
The North Wind’s Weir project is on a 3.1-acre parcel of King County’s Cecil B. Moses Park on the free-flowing Duwamish River about a mile upstream of Turning Basin No. 3. The Elliott Bay/Duwamish Restoration Program purchased 1.03 acres of the park to construct an intertidal basin. The site was originally developed in the 1930’s and 1940’s for single family residential housing. All dwellings have been removed. A steep bank along the river right-of-way sloped downward (almost vertical) approximately 20 feet to the riverbed where the shoreline was poorly protected by riprap and debris in the lower intertidal to subtidal areas. Summary taken from the NOAA Northwest Region DARRP webpage (http://www.darrp.noaa.gov/northwest/elliott/nww.html).
A 1.03-acre intertidal basin was constructed by excavating from an elevation of +6 to +15 feet MLLW. A curvilinear edge creates a more natural appearance and maximizes habitat diversity at the zone edge. A connection to the Duwamish River was made at the northeast end of the property and will be achieved by using natural bank slopes stabilized with vegetation. The 'softer" engineering approach will allow a more natural stabilization process to occur at the site. A riparian buffer was planted, incorporating as many mature trees and native shrubs present on the site as possible and to restrict human access from the surrounding park. The intertidal project with 500 feet of intertidal river frontage and a one-acre intertidal off-channel lagoon, is complemented by upland park improvements undertaken by King County, including parking, restroom facilities, trails, shoreline stabilization, plantings, and interpretive features highlighting the cultural significance of the site to Native Americans.
Monitoring for intertidal habitat success will be conducted until 2015 under the Elliott Bay/Duwamish Restoration Program's restoration monitoring plan.

An additional 0.09 acres of riparian native plants were installed in 2008 on the northern most sections of the site by People For Puget Sound.
