Floodplain Revised within the City and County of Broomfield

The City and County of Broomfield, working with Loewen Engineering, Inc., is applying for a map revision from the Federal Emergency Management Agency (FEMA) to revise the Flood Insurance Rate Map along the City Park Channel and South Tributary floodplains to reflect updated topography and accurately map the floodplain. Loewen Engineering, Inc. is proposing the revision to reflect updated topography and accurately map the floodplain.

The Flood Insurance Rate Map (FIRM) for a community depicts the floodplain, or the area that has been determined to be subject to a 1% or greater chance of flooding in any given year. The FIRM is used to help the community with floodplain management.

The floodway shall be revised generally between Spader Way and Compton Street; specifically from a point 850-ft. downstream of Main Street to a point 171-ft. upstream of Compton Street. The South Tributary floodway shall be revised from its confluence with the City Park Channel to Highway 287. As a result of the map revision, the regulatory floodway will widen\narrow within the revised area.

The City and County of Broomfield Engineering Department, in accordance with National Flood Insurance Program regulations, has given notice to property owners who will have a change to the flood hazard mapping on their property. The map revision will also result in:

  • Increases and decreases in the 1-percent-annual-chance water-surface elevations
  • Widening and narrowing of the 1-percent-annual-chance floodplain

Visit the Floodplain web page for maps and a detailed analysis of the flood hazard revisions. Or those can be reviewed at the Community Development office at the George Di Ciero City and County Building:
