Docket DC-18-0002: Amendments to the Boulder County Land Use Code for Solar-related Uses and Regulations

Request: Review of draft Land Use Code Text amendments regarding Solar Energy System uses and related provisions. (Staff planner: Sinead O’Dwyer)

Dear Stakeholder/Interested Party,

On May 10, 2018, the Board of County Commissioners authorized Land Use staff to pursue text amendments to the Boulder County Land Use Code specific to solar-related uses and regulations.

Why: Staff identified a need for updating the existing language and structure of the code, increasing the opportunity for community solar gardens in the county, and better facilitating solar development on buildings and parking areas.

Summary of Proposed Text Amendments:

• Change principal use categories for improved organization• Change ground-mounted size categories from an electrical capacity basis to an acreage basis• Allow Medium and Large Solar in more zoning districts (T, B, ER and RR un-subdivided)• Revise provisions for Forestry and Agricultural zones• Reduce review requirements where appropriate• Allow solar on Significant Agricultural Lands given additional provisions
