March 2026: New Floodplain Development Permit Available for Public Comment

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 July 4, 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 16 business days.

Public comment on this matter can be submitted through the Boulder County online portal, by email to Transportation, or in person at the next Board of County Commissioners meeting. Written comments received by 5:00 PM the day before the hearing will be included in the public record.

Resources

Volunteers contributed over 3,647 hours to this program last year. The Transportation coordinates with 22 nonprofit partner organizations throughout Boulder County to deliver services.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $338,000, making it one of the largest collaborative efforts in the county’s history.

Background

The Betasso Preserve open space property encompasses 597 acres and features 12 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

The program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.
