Document Description
The Alacena West Road runs along the north side of the Sweetwater Reservoir Property. It is a 15-foot dirt road and the only road that connects the west to the east side of the reservoir. The road was originally built in 1991 as part of the Urban runoff Diversion System (URDS), and it is mainly use for patrolling and to access existing facilities and project sites. Where the road crosses and existing drainage and URDS forebay, the road has a 24-inch culvert, and it was recently noted that the culvert and road are heavily damaged (collapsed culvert and road erosion). Potential for road failure is high if prompt action is not taken. The emergency repairs include excavating the north end of the 24-inch pipe sufficiently to remove the existing coupling and install a new one. The section of the pipe that failed will then be replaced and the original 2:1 slope will be rebuilt (see Figure 3). Mirafi 140 stabilization fabric will be placed on the slope around the new section and approximately 2 cubic feet of 6-12" rip-rap will be placed on top of the fabric. There will be about 4 yards of material to be removed and replaced, with 3 additional cubic yards to rebuild the slope.

Notice of Exemption

Exempt Status
Statutory Exemption
Type, Section or Code
S:15269(b)(c)
Reasons for Exemption
The project addresses the need to replace a failed 24-inch culvert and repair the 15-feet access road. If left unattended, irreparable damage to the road and/or downstream structure could occur (including damage to diversion and bypass gates of the Sweetwater Reservoir Urban Runoff Diversion System). The emergency repairs are specific actions to prevent or mitigate an emergency, as described in the State CEQA Guidelines § 15269©. Similarly, the emergency project would repair publicly owned service facilities to maintain a service to essential facilities, as described in the State CEQA Guidelines § 15269(b).
