NOTICE OF INTENT TO ADOPT A MITIGATED NEGATIVE DECLARATION

PROJECT TITLE: Brannan Mountain Water Storage Tank

PROJECT LOCATION:

The proposed project is located on the north side of the road, ½ mile up Brannan Mountain Road, off State Highway 96, in Willow Creek, CA.

PROJECT DOCUMENTATION:

PROJECT DESCRIPTION:

Willow Creek CSD is proposing to construct and operate a tank in Pressure Zone 1. The proposed storage tank will be constructed in the middle of an unaddressed, 0.5-acre parcel (Assessor Parcel Number 522-492-011-000) that is owned by Willow Creek CSD. The tank will be constructed of bolted steel plates, and will be painted to blend with the surrounding tree colors. The steel tank will be constructed on a concrete ring wall foundation on an excavated and graded level area. In addition, the proposed project includes on-site pipelines, valves (above and below ground), drain lines, storm drain culverts, chain link fencing and gate, and asphalt pavement around the tank.

The final tank size will be determined after several factors are considered, including available funds. Two sizes of steel tank are analyzed in this Initial Study: a 72-foot diameter tank that can store 650,000 gallons of water; and a 60-foot diameter tank that can store 409,000 gallons (37% reduction in volume).

The existing access road (250 feet in length) between Brannan Mountain Road and the tank site will be widened and paved to a top width of 15 feet. The access road is located within a public utility easement and access easement that is approximately 40 feet wide and the entrance is along Brannan Mountain Road. The public utility easement is on a privately-owned 48-acre parcel (Assessor Parcel Number 522-492-012-000) that is adjacent to the parcel owned by Willow Creek CSD (the tank site).

Also proposed is a new water pipeline that connects the proposed water tank to the existing distribution system located at the intersection of Brannan Mountain Road and Stage Coach Lane. The proposed water pipeline is 12 inches in diameter and will be placed 36 inches below the existing surface of the ground. The pipeline will run for approximately 250 feet from the new tank to Brannan Mountain Road underneath the access road. Then, the pipeline will run for approximately 250 feet along the north shoulder of Brannan Mountain Road (and within the road right-of-way) to the northeast corner of the intersection of Brannan Mountain Road and Stage Coach Lane, where it will tie in to an existing 8-inch waterline.

SIGNIFICANT EFFECTS ON THE ENVIRONMENT:

None, with the mitigation measures identified in the Proposed Mitigated Negative Declaration.
