DESCRIPTION
Description
Enhance the connectivity of Deer Creek and the associated estuarine wetland with the nearshore by replacing the two concrete culverts with an oversized culvert or a trestle bridge. Include in the project an assessment of the tidal lagoon just north of the creek mouth and whether the lagoon connection or lagoon itself can be enhanced.
Opportunities, Constraints, and other Considerations
Site hosts several small tidal lagoons upstream of tracks that could be improved. Significant amount of forested area in basin. Deer creek is too steep for fish passage.
NOTES
This option was considered by Sound Transit for its mitigation plan, but it was rejected for cost and logistical reasons. Site hosts several small tidal lagoons upstream of tracks that could be improved. Significant amount of forested area in basin. Deer creek is too steep for fish passage. Some individuals expressed concern over installing a trestle on this site, which may actually eliminate the lagoon upstream of tracks. Several participants felt that this was probably not the best site for a trestle. Concern was also expressed about water quaility from road runoff at the site being a threat to juvenile fish.
