Planning commission recommends board adopt updated Safety Element with new mining‑hazards section
Loading...
Summary
The commission voted 5–0 to recommend that the Board of Supervisors adopt amendments to General Plan Chapter 10 (Safety Element), which add a separate mining hazards section, new wildfire and extreme‑heat policies, and updates required by SB 99 and AB 747, and to forward the negative declaration for that text amendment.
The Nevada County Planning Commission unanimously recommended the Board of Supervisors adopt proposed amendments to the county’s General Plan Safety Element and the associated negative declaration.
Associate planner Zachary Bridal and senior planner Steve Geiger presented the 2026 Safety Element update, which staff said incorporates the 2025 local hazard mitigation plan, the county’s evacuation study, and state requirements under SB 99 and AB 747 to identify residential areas lacking two emergency evacuation routes and to evaluate evacuation route capacity and viability. Bridal said the safety element applies to all unincorporated areas of Nevada County and that the update reorganizes hazard categories, adds new policies for extreme heat and environmental justice, and separates mining hazards from hazardous materials into a standalone section.
Steve Geiger described stakeholder outreach and agency review: staff distributed drafts to roughly 280 parties, consulted with the Board of Forestry, Cal OES and the California Geological Survey (which requested minor geological edits), and incorporated feedback from local emergency services and air‑quality staff. Geiger said the document was circulated with a negative declaration for public review and that the draft included technical additions such as a new figure on extreme‑heat exposure levels and the county’s resource resiliency roadmap.
Commissioners asked whether the new mining‑hazards section would have altered past applications; staff said the changes are primarily focused on legacy‑mine cleanup and site‑assessment policies (Phase I environmental assessments and coordination with state agencies) rather than adding new standards for future mining projects. Staff recommended the commission forward the negative declaration (EIS25‑0001) and the amended Safety Element to the Board of Supervisors.
A motion to recommend that the Board adopt the negative declaration and the Safety Element amendments, as amended by the April 15, 2026 memorandum, passed unanimously. Staff said the update includes numerous policy additions related to fire hazards and protection, roadside vegetation management, emergency water storage, and environmental justice.
The commission closed the item and moved to other business.
