The Project includes removal of the existing 2.0-million-gallon tank and construction of 3.41-million gallon, 40-foot-high (roof height), 1 55-foot-diameter welded steel replacement reservoir on substantially the same footprint as the existing tank. The new tank will have a wider diameter than the existing tank and will extend into the area currently used for the paved circular access road surrounding the existing tank which will require a new 1 5-foot-wide paved access road to be constructed surrounding the new tank. This new asphalt road around the tank is part of the project, along with landscaping, electrical and instrumentation upgrades, and piping improvements. The existing perimeter chain-link fencing will remain.
The Project will result in impacts to 0.76 acres of California tiger salamander (Ambystoma californiense) habitat including semi-permanent impacts to 0.53 acres, and permanent impacts to 0.23 acres of California tiger salamander habitat. The project is expected to result in incidental take of California tiger salamander, which is designated as a threatened species under CESA. The ITP Amendment referenced above as issued by CDFW authorizes incidental take of species listed under CESA that may occur as a result of Project implementation and changes the previously authorized temporary impacts to semi-permanent impacts.
