Douglas County Offers 50% Cost-Share for Wildfire Mitigation, Up to $25,000

For homeowners on the wooded edges of Castle Rock and Highlands Ranch, the cost of wildfire mitigation has long been one of the most effective deterrents against completing it. Douglas County is trying to change that calculus: starting April 13, its Wildfire Mitigation Cost-Share program will cover 50 cents of every dollar spent on qualifying work, up to $25,000 per property.

The program targets the Wildland-Urban Interface, the broad swath of Douglas County where subdivisions and natural fuels share the same terrain. That geography includes Castle Rock, Highlands Ranch, Parker, Lone Tree, and the surrounding unincorporated areas where developed lots back against dense, fire-ready vegetation. Eligible work covers the fundamentals: creating defensible space, thinning woody vegetation, removing dead wood and slash, and severing the fuel ladders that allow ground fires to climb into tree canopies.

The county's 2025 results show what the program actually pays for. Last year, matching funds reached 146 properties, including 12 homeowners' association projects, with a total county investment of $764,950. That works out to roughly $5,240 in county funding per property on average, implying mitigation scopes ran about $10,500 in total, with homeowners covering the remaining half. Projects approaching the $25,000 county cap represent total scopes near $50,000 of work, with the program absorbing half regardless of scale.

HOAs and neighborhood groups can access deeper funding pools: up to $50,000 for larger community mitigation projects and up to $7,500 for community-level chipping or slash-pickup programs. The county explicitly encourages adjacent homeowners to coordinate and apply together, both to maximize contiguous defensible space and because clustered applications receive priority in the competitive review.

Two events will help residents plan before the window closes. A free open house runs Saturday, May 9, from 10 a.m. to 1 p.m. at the Douglas County Fairgrounds in Castle Rock, where mitigation experts will offer site-specific advice, demonstrate equipment, and walk through how defensible space work intersects with insurance coverage and building requirements. A live town hall follows on May 20, and the Douglas County Board of County Commissioners has scheduled a panel titled "Courageous Conversations: Your Home and Wildfire," though the date and location for that session have not been released.

Applying requires three documents: a detailed scope of work, a site map showing where treatments will take place, and two contractor estimates from the county's approved contractor list. That last requirement is the most common source of delays. Estimates from unlisted contractors do not qualify, and assembling two bids from the approved roster takes more lead time than most applicants anticipate. The county's guidance is to begin now.

The first 2026 window runs April 13 through May 13. A second period is anticipated in late 2026, with no dates confirmed. Homeowners who miss May 13 will wait months for another chance.

Sheriff Darren Weekly has already issued Stage 1 Fire Restrictions for unincorporated Douglas County under Ordinance No. O-012-004, prohibiting open fires, open burning, and fireworks. The county spent nearly $765,000 on mitigation matching in 2025 and has set an explicit goal of reaching more WUI properties this year. Program details and application materials are available through the county's website.
