CAJS-ENV Environmental Determination, May 2024. All other versions obsolete.

ENVIRONMENTAL DETERMINATION

Project Description:

The project includes roadway and culvert improvements along approximately 13,967 linear feet (2.65 miles) of roadway along San Benito Road and Range Road.

The project would widen and improve Range Road, which provides access to all six shooting ranges on Camp SLO, including the Alpha, Bravo, Charlie, Delta, Echo, and Foxtrot Ranges, as well as the Urban Training Complex. The project would include improvements to eight existing corrugated metal pipe (CMP) culverts within Range Road. Proposed improvements to existing culverts would generally include replacement of CMP culverts with high-density polyethylene (HDPE) pipe culverts, installation of rip-rap materials, and/or retaining or replacing existing concrete headwalls. The project would include the reconstruction and widening of Range Road to include one 11-foot-wide vehicle travel lane in each direction with 1- to 2-foot-wide shoulders on each side of the roadway. Existing barbed-wire fencing along the edge of the roadway would be reconstructed outside of the new roadway edge following completion of roadway improvements. An existing cattle guard located within the roadway would be removed and reconstructed to match the new road width near the same location. Existing utility poles located within the project site would be protected in place during construction activities. The project would also include burial of empty conduit underneath Range Road at the entrances to each shooting range to accommodate potential future utility connections.

The San Benito Road portion of the project would reconstruct and widen San Benito Road to include one 11-foot-wide vehicle travel lane in each direction with 1- to 2-foot-wide shoulders on each side of the roadway. This would include improvements to two existing CMP culverts within San Benito Road. In addition, the roadway centerline would be offset by 1 to 2 feet at certain locations in order to avoid impacting existing utility poles and to minimize grading within the creek adjacent to the roadway, existing barbed-wire fence located along the sides of the existing roadway would be either protected in place or rebuilt following construction activities, and existing overhead utility poles located in close proximity to the existing roadway would be protected in place. The existing State of California 8-inch underground water pipeline that bisects the San Benito Road alignment would also be protected in place and would not be affected by project activities.

A CEQA Initial Study and Mitigated Negative Declaration (IS/MND) has been prepared for the project.

Mitigation measures from the IS/MND will be incorporated into the project, see Mitigation, Monitoring and Reporting Program of the IS/MND.

This project has been reviewed in accordance with the National Environmental Policy Act (NEPA) and determined to qualify for NEPA Categorical Exclusion (CX) G2: Repair and maintenance of roads and trails. A NEPA Record of Environmental Consideration is REQUIRED, see below.
