Donkey Creek Restoration 
Gig Harbor, Washington
Client: City of Gig Harbor

Until the early 1950s, Donkey Creek flowed freely from its headwaters to Austin Estuary and into Gig Harbor Bay. In the 1950s, much of the estuary was filled in and a 300-foot-long, 36-inch-wide culvert was installed to divert the creek beneath Harborview Drive. The goal of this project was to daylight Donkey Creek, restoring it and associated estuarine habitat to its near natural condition. The project evolved into a phased program of improvements to Austin Estuary and Donkey Creek with reconfigured roadways, a new 80-foot-long bridge over Donkey Creek, and a 14-foot-wide shared use trail linking Austin Park to Donkey Creek Park along the waterfront.
