Work begins on the Harper Estuary Restoration Project with SE Southworth Drive closure

(Port Orchard, WA) - A portion of SE Southworth Drive will close for up to eight weeks beginning Wednesday, September 21 as part of a project to restore the Harper Estuary. Kitsap County Department of Public Works (County) is partnering with Washington Department of Fish and Wildlife (WDFW) and the Washington Department of Ecology to restore the Harper Estuary. The project will restore tidal influences and natural habitat impacted by industrial fill, undersized culverts, and relict roadway fill. The project is planned in two phases.

Washington Department of Fish and Wildlife (WDFW) is the design lead for Phase 1. This phase of the project removes industrial fill—primarily related to the former brick factory—from the estuary. In addition, a 16-foot, three-sided concrete culvert will replace the existing 24-inch concrete culvert under Southworth Drive to improve fish passage and increase tidal exchange. Manchester Water District, Puget Sound Energy, CenturyLink, and Wave Broadband will be relocating their utilities along the roadway during this phase.

To accommodate the work in Phase 1, SE Southworth Drive will be closed from September 21 through November 16 from SE Olympiad Drive, extending 500 feet to the south. A detour route will be in place to direct motorists around the project. A map of the detour route is available on the County’s project website

In addition to the road closure, Harper Park will close September 15 to allow the contractor to stage equipment and construction supplies. A pedestrian path from SE Southworth Drive to the trailhead in the park will be maintained during the work.

The second phase of the project—designed and managed by the County—removes the existing 36-inch diameter culvert and associated road fill on SE Olympiad Drive and replaces it with a 120 foot bridge. The bridge is in preliminary design by Otak Inc. and is anticipated to go out for bid in early 2017 once funding is secured.
