Port Townsend Bay Eelgrass
Voluntary Anchor Protection Zone
Overview

The eelgrass beds along the shorelines of downtown Port Townsend support multiple ESA listed and distressed stocks of Pacific salmon and many other priority juvenile fishes. Eelgrass beds are ranked as Priority Habitat by the WDFW.

The City of Port Townsend Shoreline Inventory of 2002 identifies the eelgrass beds of Port Townsend Bay as important rearing habitat for salmon, including the ESA listed Hood Canal Summer Chum. Juvenile salmon are observed in the early summer along the downtown shoreline.

This project protects this critical habitat by delineating a voluntary "No Anchor Zone" in order to avoid anchor damage to the eelgrass beds. The project goal is to protect, enhance and restore Port Townsend Bay eelgrass meadows by reducing anchoring in these areas. This would be achieved by educating vessel operators on the importance of eelgr ass and to get voluntary cooperation in refraining from anchoring in the eelgrass meadow off the Port Townsend downtown shoreline.

Boats & Anchors in Port Townsend Bay

Port Townsend is one of the more popular destinations for pleasure boaters in Washington's inland waters. During boating season, the nearshore area off the downtown waterfront is heavily used as an anchorage. Dur ing festivals and events, the use can become very heavy with up to 50 vessels or more anchored off the town waterfront. A small number of the vessels end up anchoring in the eelgrass meadow that extends more or less continuously from the Port Townsend boat Haven to Point Hudson. The eelgrass beds along the downtown shoreline (from Point Hudson to Indian Point) vary from 175 ft. in width between Union Wharf and Point Hudson to 410 ft. between Indian Point and the Boat Haven. The average depth at the outer edge of these eelgrass beds is -13 ft at mean lower water.

In most cases, these vessels would only have to move offshore 50 to 100 ft. (2 to 3 boat lengths for a 30ft vessel) to eliminate the anchor impact. Damage to the eelgrass bed is observable as vessels pull up anchors weighted with plants and mud. In addition, as vessels swing on their anchors or drag them in strong winds, the chains and anchors can plow up plants as well.

As a side benefit, vessel safety is enhanced. Anchors hold poorly in vegetated bottom and are more prone to dragging. Port Townsend experiences major windshifts at any time of the year and a south easterly wind can quickly turn the anchorage into a lee shore. As a result, vessels do go up on the downtown shoreline with the potential to cause property damage and pollution incidents. By moving vessels out into slightly deeper water where the anchoring is better, these incidents should be reduced.

Sign & Buoy Permitting
The MRC is working with five (5) agencies with jurisdiction over the placement of signs and buoys - including the City of Port Townsend, the US Coast Guard, the Army Corps of Engineers, the WA Dept. of Fish and Wildlife, and the WA Dept. of Natural Resources. The City of Port Townsend issued a shoreline Exemption for the placement of signs on shoreline structures.
Buoy Installation
Six to eight (6-8) seasonal marker buoys will be purchased in 2004. The delay in installation is due to the lengthy permitting process and the extensive outreach & public scoping undertaken for this project.
Public Outreach

The MRC has undertaken extensive public outreach to the community as a whole, boater groups, Chamber of Commerce, businesses, the Port of Port Townsend, the City of Port Townsend, and the Board of County Commissioners. It was important to reach agreement that these would be Marker Buoys (not Moorage Buoys) and that the "No Anchor Zone" is an area that boaters may voluntarily respect.

The MRC designed and printed 2,000 brochures and 4 temporary educational signs. The two temporary signs (Union Wharf & City Dock) were posted in time for Wooden Boat Festival (WBF) weekend September 5-7, 2003. We produced an Eelgrass Project display at the MRC booth at the Jefferson County Fair, August 8-10.

Benchmarks

The project is complementary to any future proposal for establishing mooring buoys or other types of mooring systems along the waterfront. The project is also complimentary to the Northwest Maritime Center's proposal to restore eelgrass under/around the planned pier.

This project achieves the following benchmarks:

  1. Protect productive habitat.
  2. Net productive habitat gain.
  3. Coordinate scientific data.
  4. Coordinate on an effective outreach and education effort.
  5. Achieve a scientifically-based, regional system of Marine Protected Areas
