The Federal Emergency Management Agency (FEMA) along with the Colorado Water Conservation Board (CWCB) has completed and is implementing a major effort to update the floodplain limits on the Little Thompson River in Larimer County. A floodplain is the area adjacent to a river that is expected to flood in a given storm.
The new maps will replace maps that are over 30 years old and were only approximate in accuracy. The reexamination of the floodplains is important in order to have up-to-date and reliable information about flood risks on structures and properties. This same type of effort was completed for portions of the Big Thompson and Poudre Rivers in 2006.
The revisions will affect more than 70 properties in Larimer County. If there is a change in floodplain delineation in an area, or surrounding an existing insurable structure, the change will affect applicable land use and building permit regulations, and may impact insurance requirements.
Larimer County, the Town of Berthoud, and FEMA held an open house on January 24, 2012, to provide information on the changes, assist residents one-on-one with floodplain maps, answer land use regulations questions, and provide information on appeals, insurance, and other options for impacted property owners.
The proposed floodplain information is available to review in two locations.
The links below provide additional information. We fully understand that changes to floodplain delineation can be very impactful to property owners. While the jurisdiction for delineation rests with FEMA, we will strive to ensure that citizens are informed and provided with complete and accurate information regarding the changes, requirements and options.
If you have any questions or concerns about the upcoming changes and/or their impact on your property, please contact Eric Tracy with Larimer County at (970) 498-5729 or send e-mail.
