Walterboro-Colleton County Airport Commission

Walterboro-Colleton County Airport Commission, doing business as Lowcountry Regional Airport, is a U.S. local government airport authority operating a public-use regional airport in Walterboro, South Carolina. The entity acts exclusively as a federal grant recipient under the Federal Aviation Administration's Airport Improvement Program (CFDA 20.106), receiving project grants for airport infrastructure construction and rehabilitation with no contract prime or subcontract activity in the source record.

The commission's federal footprint is entirely grant-funded, concentrated with a single customer: the Department of Transportation Federal Aviation Administration (FAA). Recent grant awards span runway rehabilitation and taxiway construction at Lowcountry Regional Airport, with work scoped across multiple phases. Recent representative projects include a $965,640 grant awarded April 30, 2026, to construct a 300-foot taxiway (final construction phase, scheduled completion April 29, 2030); a $7.18 million grant awarded August 20, 2025, under the Airport Improvement Program for Phase 2 runway rehabilitation of 6,002 linear feet of Runway 5/23 (completion August 19, 2029); and an $883,586 grant awarded September 1, 2021, for taxiway construction funded in part through the American Rescue Plan Act (scheduled completion August 31, 2025). Earlier grants supported design phases of the same runway rehabilitation initiative, including a $166,666 design-phase grant awarded August 17, 2022, and a $158,833 grant awarded September 20, 2022. The commission also received pandemic-relief funding through an American Rescue Plan Act economic-assistance grant awarded August 17, 2021, to cover operations, personnel, and facility sanitation costs.

The commission has received twenty-one federal grants with a combined obligation of $20.1 million across roughly two decades of activity. Award volume declined from 2021 peaks (three awards) through 2022 and 2023, recovered with three awards in 2025, and placed one award in 2026. All awards are FAA Airport Improvement Program project grants; the FAA Southern Region issued fifteen awards and the FAA agency-wide issued six, representing 100% customer concentration. The entity operates solely as a grant recipient with no prime contract vehicles, IDIQs, BPAs, or subcontract relationships recorded in the source data.
