Harper Estuary restoration project: lessons learned during project implementation
Presentation Abstract
Harper Estuary is a shallow embayment located in southern Kitsap County, bisected by a roadway and impacted by historic development. Juvenile salmonids are documented to use the adjacent shoreline and estuary during the spring outmigration. A brick mining and manufacturing facility was built in the southwest portion of the estuary in the early 1900s, which was then a lobe of the estuary but filled in later years. When the factory was abandoned in the 1940’s, the buildings were demolished, with much of the material pushed into the estuary. The estuary natural functions have also been impacted by road fill, both current and historic, along with other fill material for the informally constructed boat launch and upland development. The estuary was bisected by a roadway, with tidal influence also restricted by two undersized culverts. Washington Department of Fish and Wildlife partnered with Department of Ecology and Kitsap County to complete an estuarine habitat restoration project as part of the natural resource damage work associated with the Asarco settlement. Phase 1 was completed in winter 2016-17, with Phase 2 delayed until additional funding is obtained. During initial planning and design, the project encountered substantial challenges to define and remove brick material, complete tideland property boundary line surveys and determining appropriate design of replacement structures for the of undersized culverts. This presentation will discuss lessons learned from this project development and implementation.
