Title

Replacement of Drainage Inlet Structures on Foothill and Mines Road

Description

The proposed Replacement of Drainage Inlet Structures on Foothill and Mines Road Project involves the removal and reconstruction of concrete splash walls and drainage inlets at various locations along Foothill Road (from mile post 5.20 to 8.03) and along Mines Road (from mile 5.24 to 9.70). The new structures would not protrude above the pavement, thus eliminating the safety hazard caused by the existing structures. The proposed project includes improvements at 26 locations along Foothill Road and 24 locations along Mines Road. The 50 drainage inlet structure locations are identified by mile-post markers along Foothill and Mines Roads. Seven of the sites include work on drainage inlet structures on both sides of the roadway (MP 5.83, MP 6.11, MP 6.17, MP 6.58, MP 6.79, MP 6.87 and MP 7.86). The Project will result in the permanent loss or disturbance of 0.215 acres of habitat potentially used by Alameda whipsnakes (Masticophis laterlis euryxanthus) and California tiger salamanders (Ambystoma californiense) as movements and/or upland habitat, including 0.110 acres along Foothill road and 0.105 acres along Mines Road. The Project will result in the loss or disturbance of 0.105 acres of potential San Joaquin kit fox (Vulpes macrotis mutica) habitat along habitat along Mines Road. The project is expected to result in incidental take of Alameda whipsnake, California tiger salamander and San Joaquin kit fox, which are designated as threatened species under CESA. The ITP referenced above as issued by CDFW authorizes incidental take of species listed under CESA that may occur as a result of Project implementation.
