Wheatland County, Harlowton Flood Map Appeal Deadline
New flood maps have been developed for Wheatland County and the community of Harlowton. If residents or businesses feel there is an error in the map, they have a 90-day period to provide scientific or engineering data.
Date: July 14, 2022
Flood insurance rate map changes for portions of the Musselshell River and Antelope Creek in Wheatland County are nearing completion. The new maps will provide more accurate flood risk information that can help local officials and residents make informed decisions about reducing flood risks and purchasing flood insurance.
The mapping project was initiated in 2014 by counties and towns along the Musselshell River and the Montana Department of Natural Resources and Conservation (DNRC). It is part of a nationwide effort led by the Federal Emergency Management Agency (FEMA) to increase local knowledge of flood risks and support actions to address and reduce those risks.
In Wheatland County, the project involved flood study work on 37 miles of the Musselshell River from the Golden Valley County boundary to approximately five miles west of Harlowton, and three miles of Antelope Creek. New and updated flood insurance rate maps maps were produced, indicating areas at risk of flooding in a one-percent annual chance flood event. The new floodplain maps will be used to replace existing floodplain maps from 1981 and portions of the Musselshell River around Shawmut that currently have no existing floodplain maps.
The remainder of Wheatland County’s 1981 floodplain maps were not updated as part of the project.
Before new flood insurance rate maps in Wheatland County can become effective, there is a 90-day appeal period during which local residents and business owners can provide additional data for consideration before the maps are final. This appeal period ends on July 13, 2022.
Updated flood insurance rate maps for Golden Valley County went into effect in 2021, and in Musselshell, Rosebud, and Petroleum Counties in 2019.
Wheatland County and Harlowton officials encourage residents and business owners to review the proposed flood insurance rate maps to learn about local flood risks, potential future flood insurance requirements, and any concerns or questions about the information provided. The proposed maps can be viewed online at www.floodplain.mt.gov/musselshell and at the county and city offices.
If you have technical and scientific information, such as detailed hydraulic or hydrologic data, you may be able to appeal the flood risk information on the proposed maps during the 90-day Appeal Period.
