A Flood Insurance Rate Map (FIRM) and Zone information are available by request from Douglas County’s Engineering Division to residents of unincorporated Douglas County.
The following is provided as a public service to Douglas County residents upon request:
- Whether or not a property is in a Special Flood Hazard Area shown on the current FIRM of Douglas County. Insurance prices vary depending on where the property is located in the Special Flood Hazard Area.
- Additional flood insurance data for a site, such as the FIRM zone and the base flood elevation or depth.
- Flood insurance purchase requirement information to help those who may need a mortgage or loan for a property in the Special Flood Hazard Area.
This floodplain determination service is one element of the County’s Floodplain Management Program, the implementation of which leads to discounted flood insurance rates for residents of unincorporated Douglas County.
To make an inquiry, please visit douglas.co.us/water/flood-plain-insurance-information and click on the Flood Insurance Rate Map. A form may also be requested by calling the Engineering Division at 303.660.7490 or dropping by their office located at 100 Third St. in Castle Rock. The form can be faxed for your convenience.
Please note: This service does not relieve a lending institution from its responsibility of determining if flood insurance should be required as a condition of a loan. In some cases, if the property is too close to the Special Flood Hazard Area boundary, citizens may be advised that a FIRM zone determination cannot be made.
