Purpose

This program is to educate individuals who live and work in floodplains on flood hazards and the actions they can take to reduce property damage and prevent the loss of life. The program’s objective is to foster public understanding of the options for dealing with flood hazards and to promote prudent use and management of the nation’s floodplains.

Location

Projects in the Flood Plain Management Services program occur throughout Wisconsin.

Description

The program provides the full range of technical services and planning guidance that is needed to support effective floodplain management. The most common types of studies are floodplain delineation, flood hazard evaluation, dam break analysis, hurricane evacuation, flood warning and preparedness, regulatory floodway analysis, comprehensive floodplain management, flood risk reduction, urbanization impacts, storm water management, flood proofing and inventory of flood-prone structures. The program also provides assistance for conducting workshops and seminars on nonstructural floodplain management measures such as flood proofing.

Status

Current projects include a comprehensive flood study for Juneau County, and the continuation of a multi-year statewide flood inundation mapping program in Wisconsin funded through the Silver Jackets program. A groundwater analysis was initiated for Juneau County in fiscal year 2022 to complete the required information for the county and will be completed in fiscal year 2024. The flood inundation mapping projects in progress are the Baraboo River near Baraboo and the Trempealeau River at Arcadia. Baraboo and Arcadia flood inundation mapping will be completed in fiscal year 2024. In addition, fiscal year 2023 funding for a full two-dimensional hydraulic model has been obtained for the Baraboo River to evaluate the potential for flood plain water storage and for updated hydrology of the Upper St. Croix River in Solon Springs and Gordon. Potential studies yet to be funded have been requested for Wood and Adams counties, Shelby Township, Viola and Reedsburg.

Authority

The Flood Plain Management Services program is authorized by Section 206 of the Flood Control Act of 1960 (PL 86‒645), as amended.
