Document Description
Caltrans proposes the Olema Creek Tributary Culvert Replacement Project to replace a failing double culvert on SR 1 in rural Marin County, CA, at PM 24.67, which is approximately 1.8 miles south of the town of Olema. The project involves removing two undersized 24-in diameter culverts that currently convey the flows from an unnamed tributary of Olema Creek, and constructing a 44 ft long, natural bottom culvert (cast in place, reinforced concrete box) that is approximately 30 ft wide on its interior and 36 ft wide on its exterior. The culvert would require soil nail wingwalls in each quadrant extending perpendicularly from the culvert opening until it meets the 2:1 embankment slope where the wingwalls would meet the existing ground.
