We are updating the Admiralty Inlet Geographic Response Plan (GRP). An important part of the update process is hearing from the people who live, work, and play in the GRP area. To facilitate this, a public comment period will be open from Feb. 20 to March 20, 2026.

Description of the Planning Area
The Admiralty Inlet GRP encompasses about 316 square miles bounded by Port Townsend and Coupeville to the north, Port Hadlock and Port Ludlow on the west, Whidbey Island on the east, and Port Gamble and Edmonds, south. Included in the north end of Hood Canal, north of the Hood Canal Bridge. Fully or partially, the cities of Port Townsend and unincorporated Port Hadlock-Irondale, Port Ludlow, Port Gamble, Hansville, Coupeville, Kingston, and city of Mukilteo are within the planning area. The planning area falls within Kitsap, Jefferson, Island, and Snohomish counties.
More specifically, Fort Worden at Port Townsend marks the northwest boundary, the northeast border accessible by a four-mile ferry is at Fort Casey in southwest Coupeville in west central Whidbey Island and shorelines to its south end. Port Hadlock and Port Ludlow located south of Port Townsend bound the west side of the planning area and further south to the north side of the Hood Canal Bridge, over the bridge east to Port Gamble, on to the north Kitsap Peninsula, east and across marine water to the southern point of Whidbey Island. And further east of south Whidbey Island over Possession Sound, on the shoreline of Mukilteo. The planning area includes several bays, broadly Port Gamble, Bywater, Port Ludlow, Mats Mats, Oak Bays, Mystery Bay, Scow Bay, Port Townsend, Glen Cove and Skunk Bays, Admiralty Bay, Mutiny Bay, Useless Bay and Cultus Bays, and fully encompasses Indian and Marrowstone Islands.
What are Geographic Response Plans?
Geographic Response Plans (GRPs) are used to guide early response actions in the event of an oil spill. Ecology develops and updates GRPs in collaboration with state, local, and federal agencies and tribes. Each GRP is written for a specific area — for example, a river, a lake, or section of Puget Sound. Each GRP includes tactical response strategies tailored to a particular shore or waterway at risk of injury from oil.
GRPs have two main objectives:
- Identify sensitive natural, cultural, or significant economic resources at risk of injury from oil spills.
- Describe and prioritize response strategies in an effort to reduce injury to sensitive natural, cultural, and certain economic resources at risk from oil spills.
