About County Of Rock
County Of Rock, a local government entity headquartered in Janesville, Wisconsin, operates as a federal grant recipient (14% of recent awards) and sub-recipient (86%) across health, safety, nutrition, and law enforcement programs. The county does not hold federal contracts as a prime or subcontractor; all federal funding flows through grants administered by state and federal agencies.
County Of Rock's grant portfolio is heavily weighted toward human services and public health pass-throughs from Wisconsin state agencies. The State of Wisconsin Department of Health Services is the dominant prime grantee, routing federal funding for substance abuse and mental health services, Medicaid administration, child welfare, immunization, and behavioral health programs to the county as sub-recipient. The State of Wisconsin Department of Children and Families channels child welfare, child care, child support, and family support grants to County Of Rock. The Wisconsin Department of Public Instruction passes National School Lunch Program (NSLP) funds monthly to the county. Recent sub-award activity includes recurring monthly NSLP allocations (most recently April 2026), child welfare county contracts under TANF and other child-welfare vehicles (January 2026), and mental health and substance-abuse block grant allocations (December 2025). The county also acts as direct prime recipient on federal transportation and public safety grants: a $320,000 project grant from the Federal Highway Administration (FHWA) under the Safe Streets and Roads for All (SS4A) program (CFDA 20.939) awarded March 19, 2026 to develop a comprehensive safety action plan, and recurring High Intensity Drug Trafficking Areas (HIDTA) program project grants from the Office of the National Drug Control Policy (awards January 2024, January 2025, and prior years). Edward Byrne Memorial Justice Assistance Grant (JAG) block grants from the Bureau of Justice Assistance (awarded October 2021 through September 2025) fund Rock County Sheriff's Office equipment and Beloit and Janesville police department overtime and targeted enforcement.
Top customer agencies by sub-award count (55% of awards) are the Department of Health and Human Services Centers for Medicare and Medicaid Services (50 awards), the Department of Health and Human Services Administration for Children and Families (43 awards), the Department of Health and Human Services Substance Abuse and Mental Health Services Administration (28 awards), and the Department of Agriculture Food and Nutrition Service (22 and 16 awards across multiple sub-recipients). The award footprint reflects Wisconsin state government's role as intermediary; federal dollars flow from HHS, USDA, DOJ, and FHWA to state agencies, which then allocate to County Of Rock for local administration and service delivery.
Activity has grown sharply — 16 awards in 2022 to 101 in 2024 — before moderating to 53 awards in 2025 and 18 awards in 2026 year to date. Only three awards carry ultimate completion dates in the next twenty-four months, indicating limited recompete pressure. Combined dollars obligated across all awards total $54.3 million spanning 287 awards since 2006. County Of Rock holds no parent federal contracts or IDVs and operates outside commercial federal procurement channels; its federal footprint is grant-driven and routed through state administrative agencies.
