Undertake an emergency road repair project at Hearst San Simeon State Historical Monument to repair damage from the March 2023 storms. The repairs will take place in the same area as a 2021-2022 emergency project that repaired all the drainage systems in the upper access road to Hearst Castle. Work will:
- Construct a 74-foot long, 8-foot tall, steel, soldier pile retaining wall; and
- Install erosion control measures at nine (9) locations along the upper road
consisting of the following actions:
- Remove and recompact slumping soil at the upslope roadway locations to repair
- Install rock slope protection in the erosion-prone drainages.
- Install straw wattles and check dams in the drainages.
- Install hydroseeded erosion control blankets on exposed soil; and
- Install earth berms to direct water to existing systems in the Pergola.
All project work will comply with California Public Resources Code, the California Fish and Game Code, the Endangered Species Act, the Migratory Bird Treaty Act, and the Secretary of Interior standards for the preservation and treatment of historic resources.
