DESCRIPTION
The following goals and objectives will be implemented for restoring this existing Snohomish riverfront wetland:
1) Goal 1 – Re-establish, over a 50 year period, an approximately 21.6 acre tidally influenced forested, scrub-shrub and emergent marsh similar to Otter Island.
2) Goal 2 – Increase tidal exchange within the wetland through construction of a limited number of "distributary" tidal channels, which should be strategically located through additional modeling/engineering and third party review by local experts on estuarine ecosystems. These channels are intended to distribute tidal waters throughout the wetland and not to generate sufficient tidal prism to initiate formation of dendritic tidal channels. The channels should be large enough to be self maintaining currently estimated at 3 feet wide by 3 feet deep). Construction will include:
a. Extending existing channels through the marsh and out again to the Snohomish River in order to create a flow-through distributary channel system.
b. Broadening the mouths of existing channels through the shoreline berm.
c. Removing old channel blocks in the main east-west channel.
d. Extending distributary channel into the southwest corner of the Wetland, which is presently dominated by cattails.
3) Goal 3 – Create small planting islands, using dredge spoils from the new channels to establish forested (e.g. Sitka Spruce and Cedar) and scrub-shrub (black twinberry, ninebark, dogwood, willows) wetland communities.
A new 3.3-acre public park will be located north of 36th Street, just north of the North Wetland complex. Proposed improvements include parking, a group picnic building, a lawn for informal gatherings and events, a children's play area, a day-use only floating dock for recreational boats and ADA access to the river, an associated view pavilion/river overlook, and on-site stormwater treatment facilities. Pedestrian access to the river will be allowed at controlled locations, specifically a proposed gangway and float to provide access to the water for fishing, car-top boat launching, wildlife viewing, and other water-dependent recreational activities.
