MSA developed FEMA floodplain maps for nearly 300 miles of the Rock River, providing survey, modeling and mapping services

In 2011, the WDNR began the process of updating hydrologic and hydraulic data for the Lower Rock River as part of FEMA’s RiskMap program. The agency hired MSA to provide field surveys for channel ‘wet’ sections, survey data for dams, bridges and culverts, hydraulic modeling using HEC-RAS, and GIS-produced floodplain mapping for more than 300 miles of streams.

MSA’s hydraulic modelers worked with the survey and GIS teams to compile data points, photographs, notes and overview mapping that could be easily combined with GIS tools. Using geospatial data tied to a specific coordinate system, our team ran flood models for various events – 10, 25, 50, 100 and 500-year – allowing us to provide comprehensive, easy-to-use deliverables for FEMA’s use.
