County Of Charleston

County Of Charleston, doing business as Charleston County Government, is a South Carolina county government entity that operates as a prime recipient of federal grants (84% of recent awards) and as a prime contractor on firm fixed-price purchase orders, competing full-and-open with no set-aside designations. The county provides solid waste management, emergency dispatch and radio communications, landfill user fees, and community development and social services to federal agencies across twenty-nine distinct customer agencies. Charleston County Government operates through multiple named subsidiaries including the Charleston County Sheriff's Office and two fire districts, with administrative headquarters in North Charleston, South Carolina.

The county's federal work concentrates in utility and environmental services alongside HUD community development grants. On the contract side, Charleston County competes for recurring purchase orders in solid waste collection (PSC code for housekeeping and trash/garbage collection), radio communications infrastructure, and landfill disposal fees—firm fixed-price arrangements typically valued between $4,446 and $40,128 per order. Recent contract work includes a $16,095 Coast Guard purchase order for FY27 Sector Charleston radios (awarded October 1, 2026), a $6,501.60 solid waste fees order from Coast Guard Base Charleston (September 1, 2026), and a $25,483.65 National Park Service contract for 911 dispatch and radio services supporting Fort Sumter National Monument, Fort Moultrie National Monument, and Charles Pinckney National Historic Site (awarded February 2, 2026, later modified to $31,274.46). A $279,760 Department of Veterans Affairs landfill user fee contract running through December 31, 2029 anchors the county's longest-term federal commitment in waste management.

Grant activity centers on housing and community development. Charleston County has received recurring formula grants from HUD's Assistant Secretary for Community Planning and Development under the Home Investment Partnerships Program (CFDA 14.239), Emergency Solutions Grant (CFDA 14.231), and Community Development Block Grants (CDBG) program, with recent awards including $734,391.83 in HOME funding (September 24, 2025) and $158,603 in Emergency Solutions Grant funds (September 24, 2025). The county also holds project grants from the Bureau of Justice Assistance for case review screening in the Ninth Circuit Solicitor's Office and coroner services improvement ($114,200 combined approximate value across multiple awards), an opioid death investigation and prevention grant from CDC's National Center for Chronic Disease Prevention and Health Promotion, and a $397,256 FEMA project grant for countering violent extremism (September 2, 2022). Sub-award activity involves federal funds flowing through South Carolina state agencies — the Adjutant General (flood mitigation, vector control, road projects), Attorney General (prosecutors, victims' advocates, VAWA enforcement), Department of Alcohol and Other Drug Abuse Services (opioid response and substance use disorder treatment), and Department of Transportation (complete streets safety improvements).

Customer concentration is moderate. The top five customers by award count account for 67% of awards, led by the Department of Homeland Security US Coast Guard (69 awards, $621 thousand combined potential value), HUD Assistant Secretary for Community Planning and Development (52 awards), FEMA Headquarters (32 awards), Department of the Navy (20 awards), and Commerce Department NOAA (15 awards, $38 thousand). By potential value, Veterans Affairs Veterans Integrated Service Network 7 dominates with $995 thousand across four landfill-fee awards, followed by Coast Guard at $621 thousand and the National Park Service Southeast Region at $230 thousand — a divergence driven by VA's single large contract ceiling rather than volume.

The county sits on two named parent vehicles: an Indefinite Delivery Contract (N0061281C0198) with twelve task orders and a Blanket Purchase Agreement (HSCG2811A7N4001) with the Coast Guard carrying ten task orders and $14 thousand in combined potential value. Activity has remained stable to slightly declining year over year (six awards in 2022 through twelve in 2026), with only five awards (combined potential value $56 thousand) reaching ultimate completion in the next twenty-four months and therefore exposed to recompete in that window. NAICS concentration reflects the county's core service portfolio: Other General Government Support (35 awards), Legislative Bodies (19 awards), Solid Waste Collection (12 awards), Utilities Regulation and Administration (9 awards), and Hazardous Waste Treatment and Disposal (6 awards). Charleston County has held federal SAM.gov registration since 2001 and operates with a combined obligated-dollar footprint ($94.3 million across all awards) substantially exceeding the combined potential-value ceiling ($2.6 million), indicating mature, long-standing relationships anchored by recurring utility and waste-management service fees.
