Consultants recommend trimming Cameron County Airport runway to match FAA/TxDOT funding standards; court acknowledges update

Kaufman & Associates and TxDOT Aviation presented a progress update to Cameron County Commissioners Court on May 20 for the county airport’s Airport Layout Plan (ALP) update. The consultants recommended shrinking the airport’s primary runway to a planning target of roughly 5,600 to 6,000 feet and reducing its width from 150 feet to as narrow as 100 feet to match FAA/TxDOT design standards they say the county is most likely to receive ongoing funding to maintain.

Kaufman planner Chandra Burks said the ALP is a multi-phase, FAA-guided process and that the county is in phase 3 of the update. She described the airport inventory: two runways are being decommissioned, the primary Runway 13/31 is 8,000 by 150 feet, and the crosswind Runway 17/35 is 4,200 by 75 feet. "You're certainly capable of accommodating everything from small aircraft up to and including mid to large business jets," Burks said, noting the airport has room to grow.

Kaufman’s Eric Pfeiffer reviewed FAA runway-length guidance and modern business-jet performance, explaining that many modern business jets operate at useful loads far below maximum takeoff weight and therefore do not require an 8,000-foot runway. Pfeiffer said FAA and TxDOT typically will not fund maintenance on runway length beyond what is justified by the forecasted regular aircraft operations; he described a planning target in the 5,600–6,000 foot range and a runway-width standard moving from a B-2 (75-foot) to ultimately a C-2 (100-foot) design.

County staff and commissioners asked about safety, lighting retrofit costs, and emergency or military use. Staff noted TxDOT funding is typically 90% with a 10% local match; lighting and retrofit costs could be substantial and the county stressed it will seek clarification from TxDOT about who pays for lighting upgrades if a narrower runway alignment is adopted. Commissioner discussion noted the airport’s role in hurricane staging and proximity to new infrastructure (a proposed second causeway) that could affect future demand.

Consultants said the ALP will culminate in a recommended development concept, capital program and environmental review, then be submitted to TxDOT and the FAA for approval. The court voted to "acknowledge the representation" and asked staff to continue discussions with TxDOT; the county judge and staff were scheduled to meet with TxDOT Aviation director Dave Harmon on May 30 to discuss options and possible variances.

County staff emphasized that no final changes to runway length or width would occur without further review, public input and the required approvals from TxDOT and the FAA.
