- Document Description
- The purpose and objective of the project are to repair and upgrade a degraded double barreled culvert to protect the roadway from erosion and potential structural damage. The proposed construction activities will consists o: installing two plastic pipes; replacing the rock slop protection (RSP); excavating failed slopes; reconstructing and repaving the damaged roadway; replacing degraded downdrains; revegetating the disturbed soil area; and conducting erosion control. Both temporary and permanent impacts are proposed to an intermittent tributary to Forsythe Creek, a tributary to the Russian River. The project will result in temporary impacts to 3,779 feet^2 (131 linear feet) waters of the I.A. and waters of the State. However, the majority of impacts are within the existing drainage facilities (i.e. culverts and RSP). To compensate for the impacts to waters of the U.S. and waters of the State associated with project, Caltrans proposes to plant approximately 600 feet^2 of riparian vegetation adjacent to the RSP at the outfall of location PM 36.41.
