Residents urged the Garfield County Board of County Commissioners on Monday to press for an updated study of Highway 82 capacity and to scrutinize high‑density development proposals that would increase daily vehicle trips on the corridor.

In public comment, Mike Geronimus, a landowner on Highway 82, said outside developers are seeking much higher density than the parcels’ current use‑by‑right entitlements. “They’re asking for 8.5 units per acre and this is entitled to have 2.5 or 2.7,” Geronimus said, warning of traffic, retail and hotel uses that would add trips and large‑truck movements to the route.

Siri Olsen, who lives below Thunder River Market, described frequent backups on Highway 82 and asked whether the county could require the Colorado Department of Transportation to “perform an updated study of essentially the carrying capacity of Highway 82.” She said the corridor has returned to its earlier reputation as “Killer 82,” citing multiple recent fatal crashes and frequent wildlife collisions.

County staff and a commissioner reminded speakers that Highway 82 is under CDOT jurisdiction. County officials said they could prompt CDOT to review the road but indicated the agency would perform any formal traffic‑capacity or evacuation study. The commissioners and staff encouraged residents to watch the planning‑commission referral schedule for active land‑use applications and to participate in those hearings.

No formal county action was taken at the meeting; the comments were submitted during public comment and flagged by staff as related to an active planning application that will go first to the Planning Commission.

Why it matters: Highway 82 is the main, single egress corridor for much of western Garfield County. Speakers said growing development pressures from Aspen, Snowmass and other up‑valley communities are routing residential growth and commuting trips onto Garfield County roads, potentially increasing daily congestion and emergency evacuation risk.

What’s next: Residents were told the first formal opportunity to comment on any development application would be at the Planning Commission; staff and commissioners said they would monitor the schedule and follow up with referrals to CDOT where appropriate.
