Pitkin County considers threshold of 5,000 attendees for BOCC review of large events; staff to draft code updates

Pitkin County staff opened a work-session discussion Tuesday about tightening public review of large special events after a 2025 concert application for Buttermilk drew attention to the county’s administrative permitting process.

Why it matters: staff told commissioners that the Buttermilk application — which drew media attention because the applicant reported 16,000 attendees across two summer weekends — highlighted gaps between the administrative permit pathway and the public notice and comment the community expects for events with broad off-site impacts. Commissioners and staff discussed thresholds, notice methods and a multi‑year permit approach.

Staff recommendation and board discussion

- Threshold and referral: staff recommended that any proposed event inside the Urban Growth Boundary (UGB) with more than 5,000 proposed attendees per day (participants, spectators and staff) be referred to the Board of County Commissioners for a public hearing and noticed to the public. Staff recommended a lower threshold for events outside the UGB and said new events that exceed the size threshold should be sent to the BOCC for their first and second year, with subsequent years reviewed at a BOCC work session.

- Multi‑year permits: staff proposed expanding multi‑year administrative permits from three to five years for recurring events that meet eligibility criteria. Commissioners asked staff to return with clearer eligibility criteria for which events qualify for a multi‑year permit and whether an event that changes materially would trigger BOCC review earlier.

- Public notice: commissioners asked staff to create a more prominent public‑notice practice for events above the threshold (examples discussed included a clearly placed display advertisement and targeted outreach to municipalities and community organizations). Commissioners also discussed whether to expand referral lists and to coordinate a valley‑wide calendar with Aspen, Snowmass Village and other jurisdictions to avoid crowding large events on the same dates.

- Timing and appeals: the board pressed staff on turnaround timelines for applicants that must secure artists and vendors often many months in advance. Staff noted applicants should submit as early as possible and said expedited review will be available for routine renewals under multi‑year permits; staff will further clarify application timing and appeal rights in a revised permit guide.

Context and next steps

Staff said current administrative rules already allow the Community Development director to refer controversial or large applications to the BOCC, but the county’s code does not set a specific numeric threshold; surrounding jurisdictions use various approaches. Commissioners asked staff to prepare draft code language to (1) set the referral threshold (staff proposed 5,000 inside the UGB), (2) outline the public‑notice method for BOCC hearings on large events, and (3) define eligibility and conditions for multi‑year permits. Staff also said they will draft language to ensure faster turnaround for applicants who need certainty for contracting.

No formal decision was taken at the work session. Commissioners signaled support for staff’s direction to return with draft code updates and clearer public‑notice standards; staff said they will also report back on coordination with neighboring jurisdictions and the communications approach for a public hearing notice.
