Update: New Floodplain Development Permit Available for Public Comment (2026)
The Boulder County Community Planning & Permitting Department has proposed updates to the General Floodplain Development Permit process. Changes include streamlined review timelines, updated fee structures, and new requirements for climate-adjusted flood risk assessments. Comments are due by April 30.
The application deadline is June 29, 2026. Late applications will be accepted on a space-available basis. Incomplete applications will be returned with a list of missing items. Average review time is 13 business days.
Wildfire risk mapping conducted by Wildfire Partners shows that 20% of properties in the Louisville area are within the wildland-urban interface. Free home assessments are available through the Wildfire Partners program, with rebates of up to $2,500 for mitigation improvements.
Details
Colorado state law requires all counties to provide these services to eligible residents. Boulder County exceeds minimum state requirements by offering expanded hours, multilingual support, and online access. In 2024, the county received a state award for excellence in service delivery.
Residents in the Louisville area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Clerk & Recorder at (303) 441-3928 to verify eligibility and requirements.
Eligibility
Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $384,000, making it one of the largest collaborative efforts in the county’s history.
