San Juan County Public Works proposes to replace one 30 inch diameter culvert and one 18 inch diameter culvert with one new 40 foot bridge at the mouth of Cascade Creek on Orcas Island, where it flows into Buck Bay under Point Lawrence Road in San Juan County. The existing culverts are inadequately sized to convey flood flows down Cascade Creek and to allow full fish passage and tidal exchange. This project will allow full fish passage to pristine shaded riparian habitat at the lower reaches of Cascade Creek including portions which are estuarian. Targeted species include documented coho and documented coastal cutthroat. This fish passage and tidal flow barrier removal project was initiated by Public Works in August of 2003. In 2004, the culverts required emergency repair. The 2004 Hydraulic Project Approval required culvert replacement by July 2011 with a structure designed for fish passage. In 2004, the project was placed on the 6-year Transportation Improvement Program, funds allocated, and scheduled to meet the 2011 deadline. A box culvert replacement was initially proposed as a stand alone project. Further evaluation through a Nearshore Estuary Restoration Feasability study is now included and has been completed. This will ensure the replacement passage structure is sufficient for both creek and tidal flow. A separate project involving acquisition of creekside and nearshore property by the SJPT upstream and adjacent to proposed bridge location is proposed for this year's SRFB funding cycle.
