Floodplain Maps

Following the September 2013 flood disaster, Colorado has taken steps toward long-term planning and resiliency efforts for flooding and other natural hazards. In early 2015, Colorado’s Legislature passed a funding bill for the Colorado Hazard Mapping Program, which aims to provide a mitigation and land use framework in areas likely to be affected by future flooding, erosion, and debris flow events.

The Colorado Hazard Mapping Program (CHAMP) prepared updated hazard information for the streams most affected by the September 2013 flooding, including the Big Thompson watershed. Phase I & II includes field reconnaissance and survey, creating terrain models from updated topographic data-sets, evaluating hydrology (flows), and modeling to produce flood hazard area limits reflecting the changed conditions. The City will use the updated hazard information to assess risk and identify mitigation opportunities within the community. The updated information is also intended to eventually be used to update Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRM), which are used to determine flood insurance requirements.

Drafts of the floodplain maps are available for review below:

 

The City's Big Thompson Floodplain was revised during 2005 and adopted in November 2006.

Below are links to City of Loveland floodplain maps of the Big Thompson River and information of the City's Early Flood Warning System.
