Route 25 Curve Alignment Restoration

proposed

The California Department of Transportation (Caltrans) proposes to provide a permanent solution to the failure of the cut slopes of the original State Route 25 Curve Realignment Project. The proposed project would provide a permanent solution to the failed 2015 State Route 25 Curve Realignment Project by flattening the cut slopes to 2:1 (horizontal to vertical dimensions) to reduce erosion, promote revegetation regrowth, and prevent repeated slope failure. The horizontal curves and banking of the roadway will vehicles to travel through the curve more safely. Approximately 72,000 cubic yards of material would need to be excavated. The project would construct two 12-foot lanes with 4-foot outside shoulders. Existing right-of-way is approximately 30 feet from the centerline of the roadway. Because the existing right of way cannot accommodate the proposed flattening of the slopes, additional permanent right-of-way acquisition would be required. It is estimated that 17 blue oak trees and 1 valley oak tree may need to be removed to accommodate the proposed project. Impacts to trees will be offset by replacement planting within the project limits. In total, a minimum of 191 blue oak trees will be planted within the proposed planting areas. A three-year plant establishment period is proposed. The scope of the replacement planting would be entirely within the limits of this project and within existing and proposed state right-of-way.
