Document Description
Project consists of replacing an existing 24-inch diameter corrugated metal pipe that is 72 feet in length with a new 30-inch diameter smooth walled HDPE pipe of the same length. The original 24-inch CMP was damaged in August 2014 from a high density, short duration storm that also created a large scour bowl upslope of the culvert, and over topped the existing road. The new High Density Polyethylene HDPE culvert is designed to convey the 100-year storm even as required by the El Dorado National Forest Land and Resource Management Plan as amended by the 2004 Sierra Nevada Forest Plan Amendment Record of Decision. Additionally, rock rip rap will be placed for 12 feet downstream at a depth of 2 feet from the culvert outlet and will extend to the top of slope on both banks. At the inlet of the culvert, rock rip rap will be placed and used to fill and stabilize the existing scour hole to transition from the channel and rock lined inlet. The existing flow line of the channel will be maintained.
