Draft Renewable Energy Ordinance Available for Public Review
A draft ordinance updating Napa County’s development regulations for renewable energy systems has been released for public comment. Notable components are:
Codifies County’s current practices of allowing ‘accessory renewable energy systems’ such as small solar systems as a matter of right, but limits the system to meeting on-site power needs of private residences, business, and agricultural uses. Applies ministerial development standards consistent with other allowed accessory uses.
Establishes regulations for ‘commercial renewable energy facilities’ for power generation facilities that provide feed-in tariff power to the public utility grid.
Codifies County’s current practices of allowing emergency power generators for use during power outages. Generators limited in size to meet on-site power needs only.
These uses are excluded from agricultural and residential zoning districts, and allowed with a Planning Commission Use Permit in industrial, commercial, and public facility districts.
Establishes comprehensive development standards for such uses
Repeals antiquated ‘small wind energy’ code requirements that expired in 2017.
Please direct comments or questions via email to John McDowell or call him at (707) 299-1354. A public hearing before the Planning Commission is tentatively set for November 20, 2019. Upon conclusion of the Planning Commission’s recommendation, the draft ordinance will be scheduled for a public hearing before the Board of Supervisors.
