Pitkin County planning panel finds airport modernization not in conformance, cites gaps on noise and air‑quality monitoring

The Pitkin County Planning and Zoning Commission voted unanimously April 28 to find that the Aspen/Pitkin County Airport Modernization Program, as submitted, does not conform with the Aspen Area Community Plan and the Western Maroon Creek master plan. Commissioners cited missing, incomplete or inconclusive evidence on air‑quality monitoring and community noise impacts, and said schematic terminal massing and proposed parking expansion left too many unresolved questions for a location‑and‑extent approval.

The motion, made during a lengthy continued public hearing, instructs staff to refine a draft resolution for the Board of County Commissioners. Commissioner Joe Craybacher moved the finding and Suzanne seconded; commissioners present voted unanimously in favor.

Why it matters: the vote is a formal recommendation the BOCC will consider. A finding of non‑conformance does not by itself block runway repairs or other narrowly defined safety work, but it signals that the county’s elected decision‑makers should take up unresolved questions — especially on air quality monitoring, noise management and the visual and circulation effects of a much larger terminal and parking structure.

Applicants and county staff told the commission they have advanced several technical elements: the applicant’s environmental team said a NEPA re‑evaluation of earlier environmental assessments (2018 EA and subsequent reviews) showed no modeled thresholds exceeded for the project variants examined, and the airport advisory team described a new voluntary “Fly With Integrity” program that combines emissions and noise monitoring with pilot outreach.

Diane Jackson, representing the airport team, described a monitoring network installed in January 2026. “We’re monitoring for a year,” she said, noting two higher‑quality reference stations at each end of the runway plus a set of solar‑powered screening monitors distributed through the community; one large unit was taken fully online April 7, 2026. Jackson and other presenters urged the commission to allow time to collect a full 12‑month baseline — including the planned runway closure this summer — before drawing conclusions about chronic air pollution trends.

But commissioners and dozens of public commenters, including neighborhood representatives, doctors and national‑level experts who called in or submitted long letters, said modeling alone and the limited initial data are not enough. “We simply cannot go forward until we know what people are breathing,” Ellen Anderson told the panel, arguing for measured ultrafine‑particle metrics rather than modeling alone.

Several technical questions remained disputed in the hearing record. Expert Amory Lovins, calling in during public comment, told the commission that a new runway is necessary, but that widening the runway or changing the taxiway separation in ways that would allow considerably larger aircraft is not required for safety and would drive growth: “Yes, we need a new runway, but that’s nothing to do with whether we move the relative position of the runway or taxiway, nor the width of the runway,” he said.

Commissioners also singled out the terminal and parking proposals. Material distributed by the applicant showed a schematic terminal program under active design; the packet discussed an approximately 128,000‑square‑foot schematic that staff and applicants said remains in flux. Commissioners said the mass, scale and sight‑line effects of a terminal that large — together with a multistory parking structure — require more definitive design work and stronger multimodal plans before PNZ can find conformance with the county master plans’ direction to preserve visual openness, keep a low profile along Highway 82 and encourage alternative transportation.

What the applicants said: JR Fielding, the applicants’ project lead, asked the commission to focus on the application’s location and extent elements and said many operational matters fall to FAA standards. Fielding also noted the applicant will continue to refine terminal design and that some west‑side features remain pending additional environmental review.

Next steps: staff will circulate a draft resolution incorporating the commission’s edits and findings, including a targeted finding that the FBO replacement elements shown are in conformance, while the larger modernization package is not. The BOCC will receive the PNZ recommendation and will decide whether to accept or modify it. Commissioners requested a year‑long monitoring baseline (including ultrafine‑particle measurement), clearer Part 150/noise‑management commitments, and a more fully developed multimodal and parking strategy before the county moves further along the current modernization pathway.
