The Seasonal Drainage Crossing Improvement Project is part of the operations and maintenance activities as defined within the County of El Dorado Board approved and adopted this project is related to compliance with the Clean-up and Abatement Order (CAO) (R5-2009-0030) issued by the State Water Resources Control Board (SWRCB) Central Valley Region to the USFS and County for erosion control and sedimentation issues on the Rubicon Trail. The project improvements would include removing an existing timber structure crossing over an unnamed intermittent seasonal drainage channel and replacing it with a three sided bottomless steel arch, removing an existing rock ford crossing downstream of the existing crossing structure, installing erosion control type best management practices (BMP;i.e., rock slope protection, rock-lined channel, and rock fill, etc..), and installing Trail delineation BMPs (i.e., rock boulders and trail edge logs). Additional re-vegetation and channel bank stability bio-engineering BMPs will be installed up channel and down channel of the crossing to further reduce the erosion potential within the seasonal drainage. No grading would occur within the channel, construction would take place when the seasonal drainage channel is dry, most of the work would occur by hand labor, and the work is covered under existing U.S Army Corps of Engineers and Clean Water Act permits.
Existing facilities operation, maintenance, or minor alteration.
