Title

Lee Vining Rehab

Description

The Department of Transportation (Caltrans) proposes to rehabilitate the entire existing pavement area and replace, repair, or construct new facilities including drainage, sidewalks, curb ramps, driveways, street lighting, landscaping, a retaining wall, and guardrail from postmiles 50.6 to 53.1. Shoulder backing (three feet in width) will be placed where there is no sidewalk adjacent to U.S. Route 395. In addition, conceptual cross-section design options have been prepared for postmiles 51.2 to 51.7 (within the community of Lee Vining). Permanent stormwater treatment facilities are proposed outside of existing Caltrans right of way, including one drainage ditch at the northern end of and one detention basin on the east side of Lee Vining. The detention basin will require a minor amount excavation (up to one and a half feet), grading and establishing berms to capture stormwater flows and the drainage ditch will require excavation to approximately five feet deep. An additional drainage design option is being considered which would construct an approximately twenty-foot wide bioswale inside Caltrans right of way in front of the Caltrans highway maintenance station, Mono County highway maintenance station, and School parcels.
