Document Description
Approval of a Use Permit, Zone Change, Variance, Lot Line Adjustment, and Grading Permit to allow: a request to construct approximately 56-acres of floating solar panels on Napa Sanitation District’s existing wastewater ponds. The proposed commercial solar facility will produce approximately 34.7 megawatts (MW) of direct current electricity, converted to 24.5 megawatts (MW) of alternating current electricity. The proposed project includes approximately 2-miles of electrical transmission lines, with portions constructed above and below ground. The electrical transmission route will consist of 51 transmission line towers ranging in height from 38.5 feet to 74.5 feet tall. The proposed project will require the creation of one 0.13-acre electrical substation located on the northern portion of the Napa Sanitation District’s existing wastewater ponds and the 0.9-acre expansion of an existing Pacific Gas and Electric (PG&E) “Tulucay” electrical substation located on Anderson Road. The expansion of the PG&E electrical substation will require approximately 24,700 cubic yards of earthwork.
• The construction of the 56-acre commercial solar facility, 42 of the proposed electrical transmission towers, and the 0.13-acre new electrical substation are within the permitting jurisdiction of Napa County. The project includes a request to change the Zoning District of the developed portions of the project parcels from Agricultural Watershed: Airport Compatibility (AW:AC) to Public Lands: Airport Compatibility (PL:AC) to support the establishment of a Commercial Solar Facility. The project includes request for a height Variance to construct above ground portions of the transmission lines taller than the Zoning District’s maximum height of 35 feet. The Variance requests relief of the height standards to establish 42 transmission line towers, within the jurisdiction of Napa County, at a height varying between 38.5 feet and 70 feet tall. A Lot Line Adjustment is proposed between Assessor Parcel Numbers 046-400-004-000 and 046-400-057-000, to accommodate the PG&E electrical substation expansion.
• The installation of 8 electrical transmission towers and the undergrounding of approximately 1,800 feet of electrical transmission lines are within the permitting jurisdiction of the California Department of Transportation (CalTrans).
• The electrical substation grading and electrical equipment associated with the 0.9-acre expansion of an existing Pacific Gas and Electric (PG&E) “Tulucay” electrical substation located on Anderson Road and one Point of Connection Outside (POCO) transmission tower are within the permitting jurisdiction of the California Public Utilities Commission (CPUC).
