County Of Siskiyou

County Of Siskiyou, doing business as Tax Collector, is a U.S. local government entity (California county) that serves federal agencies primarily as a prime contractor and grant recipient for pesticide monitoring and enforcement, aviation support services, and airport infrastructure improvement on federal lands in northern California. The county operates across 73% prime awards and 27% sub-awards, competing full-and-open on all work; it holds no SBA set-asides and receives no set-aside designations on its federal contracts or grants.

Siskiyou County's concrete capability portfolio centers on three areas: agricultural regulatory services, airport operations support, and airport infrastructure planning. On the agricultural front, the county holds statutory authority under California Food and Agricultural Code 11501.5 to conduct pesticide monitoring and enforcement on federally leased lands. In September 2026, the Bureau of Reclamation awarded a sole-source $424,097 purchase order for pesticide monitoring and enforcement at Tule Lake and Lower Klamath National Wildlife Refuges, running through May 2031 with a nine-month base period plus four optional one-year extensions; the county must provide qualified agricultural inspectors to monitor at least 25 percent of pesticide applications, conduct 100 percent inspections of restricted-use pesticides and chemigation systems, and deliver incident reports within 48 hours and monitoring reports within 14 days. On aviation support, the county operates four airports within Klamath National Forest (Weed, Siskiyou County, Butte Valley, and Scott Valley airports) and holds a single-award $350,000 Indefinite Delivery Contract from the U.S. Forest Service Pacific Southwest Region running through December 2029 for incident support services including landing fees management, parking, fuel flowage, and aviation support for emergency response and forest management operations; recent delivery orders under this IDC include $49,610 (August 2025) and $25,000 (August 2025) task orders. On airport infrastructure planning, the county receives Federal Aviation Administration formula grants under CFDA 20.106 (Airport Improvement Program, Infrastructure Investment and Jobs Act Programs) for master plan development and pavement rehabilitation: a $4.44 million grant awarded September 2023 funds apron and taxiway pavement rehabilitation at Weed airport through September 2027; a $530,092 grant awarded August 2022 developed a master plan for Montague airport; and a $454,542 grant awarded September 2025 updates the airport layout plan for Fort Jones airport through September 2029.

Customer concentration is distributed across Interior and Agriculture with heavy Forest Service presence. The top five funding agencies account for 61% of award count, led by USDA Forest Service Pacific Southwest Region (22 awards, $655 thousand combined potential value) and FAA Western Pacific Region (18 awards). By potential value, the top five account for 98% of combined potential value, with the Bureau of Reclamation ($1.3 million across five awards) and Forest Service ($655 thousand across 22 awards) anchoring the portfolio. The county also receives federal grant sub-awards from California state agencies (California Department of Public Health, Office of Emergency Services, California Department of Child Support Services) for vaccine-preventable disease prevention, women-infant-children nutrition programs, emergency management, and victim witness assistance; these sub-awards flow through state grantees rather than direct federal funding.

Activity has grown year over year with significant spikes: 2022 saw six awards, 2023 six awards, 2024 five awards, 2025 seventeen awards, and 2026 five awards to date. Recent recompete exposure is minimal — only one award faces ultimate completion within the next twenty-four months. The county's parent contract vehicle is the Forest Service's Indefinite Delivery Contract 1202RZ24T0030, which carries three task orders and $82 thousand in combined potential value. NAICS concentration reflects the county's focus: Other General Government Support (11 awards), Support Activities for Forestry (9 awards), and Landscaping Services (4 awards). PSC codes show Environmental Systems Protection—Pesticides Support (4 awards), Support Professional Other (4 awards), and Lease/Rental of Miscellaneous Buildings (4 awards).

Siskiyou County has held federal contract and grant relationships since 2003 and is registered in SAM.gov since 2004. The county operates as a local government entity with specialized expertise in federal land management, environmental conservation, and airport operations leveraging its geographic position in northern California's Klamath National Forest region. Its federal work is characterized by small-dollar, long-duration relationships on forest management, pesticide regulation, and regional airport infrastructure — typical of county-level local government contracting for services tied to specific geographic jurisdictions and statutory authorities.
