Nevada County Planning Commission Recommends the Denial of Proposed Idaho-Maryland Mine

Planning Commission Public Hearing IMM

Today, after approximately 9 hours of public comment over two days, the Nevada County Planning Commission voted unanimously to recommend the denial of the proposed Idaho Maryland Mine – Rise Grass Valley Project and the Final Environmental Impact Report (EIR) to the Nevada County Board of Supervisors.

Next Steps

Following the Planning Commission’s recommendation, a Board of Supervisors Public Hearing will be scheduled no sooner than August 2023 to consider the Planning Commission’s recommendation and all public and agency comments received during the application process.

Over the next several months, the County will work to update the staff report for the Board of Supervisors Public Hearing to include public comments from the Planning Commission Public Hearing and integrate the Planning Commission’s recommendation to the Board of Supervisors. The Board of Supervisors will hold a noticed public hearing to take final action on the proposed project.
