North Central Puget Sound Geographic Response Plan (NCPS-GRP)

North Central Puget Sound is a diverse area. It includes many different types of shorelines, from large marshes on the mainland to wave cut platforms on Whidbey Island. Much of the land in the area is rural, rural residential, or conservancy. Seven state parks and dozens of boat ramps and marinas can be found throughout the region. Everett is an active port city located in the southeastern part of the area. It has an extensive waterfront, populated by wood processing facilities, marinas, parks, and vessel repair facilities. Outside of Everett, local economies are based primarily on natural resource use and tourism. Aquaculture, commercial fishing, and recreational fishing are active and important industries throughout the region. The U.S. Navy maintains two bases in the area: Naval Station Everett on Port Gardner Bay and Naval Air Station Whidbey Island near Oak Harbor.
