Curtis Hinkle specializes in comprehensive land and water resource maintenance services for federal installations, with deep expertise in herbicide application, mowing, park cleaning, janitorial operations, refuse collection, and septic/vault pumping. The contractor delivers integrated landscaping and environmental management solutions across sensitive military and public land sites, particularly around lakes and embankments in Oklahoma. Technical proficiency includes precision application of registered herbicides and pesticides, mechanical vegetation control, and compliance-driven waste removal protocols tailored to EPA and DoD environmental standards. A key differentiator is the ability to execute multi-service consolidated maintenance contracts that require coordinated, scalable field operations across diverse terrains while maintaining strict adherence to safety and ecological regulations. The contractor has established a consistent track record working with the Department of Defense, primarily supporting U.S. Army Corps of Engineers and military installation maintenance programs. Work includes long-term, base-wide maintenance contracts for recreational lakes and dam infrastructure, where services are critical to public safety, erosion control, and recreational access. Engagement patterns suggest a preference for multi-year, performance-based agreements that require sustained operational reliability and site-specific adaptability. The primary NAICS code, 561730 — Landscaping Services — reflects a focused market position in institutional and federal land management. The contractor’s work falls squarely within the niche of public infrastructure landscaping, distinguishing itself through specialized aquatic and embankment maintenance not typically offered by general landscaping firms. This vertical specialization aligns with DoD’s need for environmentally compliant, mission-critical groundskeeping on controlled federal properties. Curtis Hinkle operates as a sole proprietorship (2J entity) based in Ramona, Oklahoma, with no formal government certifications on record. The business is geographically anchored in the southern Great Plains, leveraging local knowledge to deliver responsive, on-site services to federal land management agencies across Oklahoma and surrounding regions. Its market positioning is that of a nimble, regionally focused provider of essential environmental maintenance services for federal installations.

It is a combined synopsis and solicitation with a simplified acquisition procedure ceiling of $9 million and is structured as a firm-fixed-price purchase order with fixed-rate pricing for both scheduled and unscheduled emergency services. The requirement covers approximately 76.5 acres across four distinct areas, including routine lawn care such as mowing, edging, string trimming, mulch bed maintenance, hardscape upkeep, seasonal leaf and debris removal, tree maintenance—including magnolia sucker removal and a four-foot clearance requirement at the laboratory—and shrub pruning in compliance with industry standards. Snow and ice removal services must be provided seven days a week from 7:00 a.m. to 11:00 p.m., including federal holidays, with a response goal of two hours for emergency mobilization triggered by two inches of snow, 0.5 inches of mixed precipitation, or unsafe icing conditions, and surge capacity for blizzards exceeding sixteen inches, all within a seasonal cap of twenty inches of cumulative snowfall. The contract includes one twelve-month base period beginning September 1, 2026, and four optional twelve-month extensions, exercisable solely at the Government’s discretion, for a potential five-year performance period. Quoters must be active small businesses in SAM.gov certified under NAICS code 561730 with a $9.5 million size standard and must submit all required licenses and certifications for Maryland and Howard County, which serve as a mandatory pass/fail gate—failure to provide valid documentation renders a quotation ineligible.
