Abstract: This document evaluates the impacts of the U.S. Army Corps of Engineers (Corps) repair of the Ediz Hook Beach Erosion Control Project. The purpose of the erosion control project is to protect the sand spit from erosion, thereby protecting Port Angeles Harbor, and the small boat basin from direct wave action, and maintaining access to the U.S. Coast Guard Station, Port Angeles, located at the end of the spit. In accordance with the National Environmental Policy Act (NEPA), this Draft Environmental Assessment (EA) evaluates the impacts of the emergency repair that took place in January 2016 as well as the proposed full repair to be completed in stages over a 10-year period from fiscal years (FY) 2016-2026 between stations 55+00 and 175+00 as needed based on annual structure condition assessments. An interim emergency repair performed in January 2016 consisted of repairs along a 200-ft section of the revetment between stations 170+50 to 171+50, adjacent to the Nippon Paper Industries property. The Corps placed approximately 2,550-tons of 2 to 10-ton armor stone as well as 700-tons of filter layer material. Due to the high tides during the emergency work, a full repair down to 0-ft Mean Lower Low Water (MLLW) was not possible; therefore, repairs were limited to areas above +6-ft MLLW. Future repairs and maintenance work over the next 10 years would will include the placement of armor stone, filter layer material and beach nourishment between stations 55+00 and 175+00 as needed based on annual structure condition assessments. Potential impacts of the proposed work are described in this document. Impacts would generally be highly localized in nature, short in duration, and minor scope. Impacts are not expected to be significant either individually or cumulatively.
