Abstract: This project will address a total of 13 culverts identified as restoration priorities and an additional matching 1 culvert will be replaced by project partner ADOT. Of the 13 EVOS funded priority culverts identified, two of the culverts will be removed completely and the remaining eleven will be replaced with AOP or Stream Simulation type designed culverts using an approach that combines geomorphic and hydrologic data to allow for juvenile salmonid passage, sediment transport, and flood conveyance. The culverts will be constructed to withstand a 100 year flood event and with a design life of 50 years. Furthermore, the replaced culverts will reduce maintenance of the Copper River Highway and side roads; maintenance of the culverts will be conducted by the Alaska Department of Transportation & Public Facilities (ADOT/PF).
