Floodplain Mapping – How to Stay Informed

Floodplain Mapping - How to Stay Informed

Boulder County is committed to keeping the public informed about the mapping update program in an accurate and timely fashion.

Newsletters

Newsletters will be produced and disseminated throughout the duration of the program to provide property owners and other interested parties with regular updates. The newsletters will contain information on regulatory floodplains, the National Flood Insurance Program, Code Amendments, and other relevant topics.

Public Hearings

The public hearing process for adopting new floodplain mapping and associated code amendments requires that staff recommendations are presented at one or more Planning Commission public hearings, and then, upon approval, brought to the Board of County Commissioners for another public hearing where a decision on the staff recommendation is made.

The Phase I draft floodplain maps will be presented along with Floodplain Overlay District code text amendments at a Planning Commission hearing. More information, including details about the hearing date and time is available on the Land Use docket webpage. Check back regularly for updates and new hearing information. We also suggest looking at the Board of County Commissioners agenda and the Planning Commission agenda to stay up-to-date on scheduled activities for this project.

Public Meetings

Public meetings for the Phase I floodplain mapping areas were held from December 2016 through February 2017 and were hosted in locations throughout the county near the waterways that were under review. The goal of the meetings was to gather additional information that could inform the draft mapping prior to the initial submission of the mapping data for FEMA review. All future floodplain remapping public meetings will serve the same purpose for future datasets.

Upcoming Public Meetings

This meeting will include draft floodplain maps for reaches of the Little Thompson River within Boulder County. These extents include:

  • Little Thompson West Fork – including Hemlock Drive, Hickory Drive, and County Road 82E
  • Main stem including W County Road 2 to North 83rd Street

Viewing Draft Floodplain Data Online

Draft floodplain data is published on the county’s map review platform. Final drafts for adoption will be posted at least one week prior to the scheduled Planning Commission hearing. This data is subject to change until it is officially adopted by FEMA – the county adoption process is underway to allow regulatory decisions to be made on the best available data.
