####
####
The Kitsap County Department of Public Works (the County) is working with Washington Department of Fish and Wildlife (WDFW) to restore the Harper Estuary.

The project is planned in two phases:

Design Lead for Phase 1 - Washington Department of Fish and Wildlife, (WDFW) Project Manager, Doris Small, 360.902.2258

Design Lead for Phase 2 - Kitsap County Department of Public works, Project Manager, Gunnar Fridriksson, 360.337.5777

Four project components:
1) Estuary restoration consisting primarily of removal of historic fill and reconnection of tidelands, which also includes the cleanup of contaminated soil that has been detected in isolated areas south of
SE Olympiad Drive. (Phase 1) Complete.
2) Replacement of a 24-inch culvert on Harper Creek which runs under Southworth Drive with a 16'x11' three-sided culvert. (Phase 1) Complete
3) Removing the existing 36-inch diameter culvert and associated road fill that exists where Olympiad Drive crosses Harper Estuary with a 120 foot bridge. (Phase 2)

4) ADA compliant beach access path (Phase 2)

The goal of the project is to restore tidal influences and natural habitat that are now impacted by the ineffective culverts on Southworth and Olympiad Drives and road fill. The County is the design lead for the culvert replacement and beach access path.

Project schedule:

~Southworth Drive culvert and estuary restoration is complete.

~The Bridge design, including plans and specifications, is being completed by Otak Inc. The project is anticipated to go to bid early 2018. Bridge construction will follow once funding is secured.

Funding:
Phase 1
: This portion of the project is currently funded by Asarco Mitigation Funds at $4.1 million. The first two components of the project cost approximately $2.9 million. We anticipate the state legislature will re-appropriate the remaining balance to Phase 2 of the project, for construction.
Phase 2: The design portion of this portion of the project is approximately $1 million dollars and has been paid for partially by the Asarco funds and a grant from the Salmon Recovery Board. The County and WDFW are working together to fund the construction of the bridge and a beach access path. A construction for the remaining project components is estimated to be $4.8 million, which is currently not funded unless the state legislature funds the Estuary and Salmon Restoration Program (ESRP) at $14 million.

Total project cost is roughly $8.5 million.
