Always look at the maps for both the FEMA floodplain and City floodplains to determine if a property is in a floodplain

Although City maps show areas outside city limits, do not use the maps to make floodplain determinations in Larimer County. Contact Larimer County Engineering at 970-498-5700 for County floodplain map information.

Please refer to the CSU Floodplain Management website for floodplain mapping and requirements on CSU’s Main Campus.

You can also obtain a copy of the FEMA maps on the FEMA website. Check out FEMA's tutorial to learn how to create a specific map.
