About County Of Jefferson
County Of Jefferson Department Of Administration Division, doing business as Jefferson County Court, is a U.S. local government entity based in Hillsboro, Missouri (729 Maple Street) that receives federal grants as a prime recipient for infrastructure, public safety, and community development projects but does not hold federal contracts. The entity operates as a county government structure and competes for and receives direct federal grant awards across multiple agencies and programs, with 47% of recent awards held as prime recipient positions and 53% as sub-recipient pass-throughs from state and local intermediaries.
Jefferson County's grant portfolio centers on three federal program streams. Community Development Block Grant (CDBG) entitlement formula grants from the Department of Housing and Urban Development's Assistant Secretary for Community Planning and Development account for the largest award volume (20 awards per the top-customers breakdown covering 88% of recent activity). The county has held multiple CDBG entitlement grants since 2021 with ultimate completion dates extending through 2033, using funds for viable urban community development, housing, and economic opportunity initiatives for low- and moderate-income persons. Edward Byrne Memorial Justice Assistance Grant (JAG) block grants from the Department of Justice's Bureau of Justice Assistance (13 awards) support law enforcement equipment and crisis intervention services — representative work includes purchases of APX8500-series dual-band radios ($240,000 planning grant period through September 2029 for the Sheriff's Office, awarded October 2023) and staffing for a second mental health coordinator position within the county's crisis intervention team (awarded September 2021, completed December 2023). A $240,000 planning grant from the Federal Highway Administration under the Safe Streets and Roads for All (SS4A) program (CFDA 20.939) awarded April 2026 funds comprehensive safety action plan development for the county, extending through September 2029.
Jefferson County's dollar footprint reflects heavy involvement in transportation infrastructure sub-recipient work. The Federal Highway Administration ranks as the dominant funding source by award count (42 awards), with the vast majority flowing through Missouri Department of Transportation as the prime grantee — Jefferson County receives sub-awards for county-level roadway resurfacing, sidewalk improvements, bridge deck replacement and rehabilitation, shared-use path construction, and related safety improvements. Representative sub-awards include sidewalk and drainage improvements on 5th Street from High Street to Beckett Street (awarded March 2026), bridge replacement on Sycamore Lane over Bear Creek (awarded February 2026), and road realignment with guardrail upgrades on Hunning Road (multiple awards between February and October 2024). A marine vessel engine repower sub-award for the Jefferson County Port Authority serving the Mississippi and Missouri Rivers (awarded July 2025 and sub-awarded earlier in March 2024) reflects infrastructure diversification. Activity increased sharply in recent years, rising from two awards in 2022 to 24 in 2024, with a moderation to 11 awards year-to-date in 2026. Only three awards face ultimate completion within the next twenty-four months, reducing immediate recompete pressure. The county has also received sub-awards for cybersecurity grant funding and emergency management performance grants, with sub-recipients including the Missouri Department of Public Safety and Missouri Department of Social Services for child support enforcement pass-throughs. Thirteen distinct federal customer agencies have awarded or sub-awarded to Jefferson County, with combined dollars obligated across all awards totaling $47.1 million.
