Green River/Duwamish Geographic Response Plan (GRD-GRP)

Pedestrian Bridge over the Duwamish River by North Wind's Weir

The Green River/Duwamish GRP covers the river from North Wind’s Weir in Tukwila to the base of the Howard Hanson Dam. The Green River/Duwamish watershed has three distinct geographic areas: the Duwamish River and Waterway, the lower Green River, and the middle Green River. The cities of Tukwila, Renton, Kent, Auburn, Black Diamond, Ravensdale, and Palmer are included in this area.

Interim Updates

In between plan updates, GRP strategies are tested during drills and actual spill events. The results of these tests may require changes to certain response strategies, notification strategies, staging areas, or boat launch locations. Eventually, these changes will be fully incorporated into the plan. Until that time, please use the updated strategy and information sheets below in lieu of that provided for similarly numbered locations in the published plan.

No interim updates currently available
