Flood Map Revision Update:
The City of Glendale has requested a flood map revision from the Milwaukee Metro Sewerage District (MMSD). Although the effective Flood Insurance Rate Maps (FIRM) are dated 2008 for the City, the original hydrologic and hydraulic analyses were performed in 1977, with a re-study by the Southeastern Wisconsin Regional Planning Commission (SEWRPC) in 2006. Since this time, the availability of improved hydraulic modeling combined with more accurate topographic information enhanced by field survey data will result in a more appropriate floodplain representation.
MMSD previously began preliminary modeling of this corridor. In late 2020, the City and Clark Dietz, Inc. were asked to take the preliminary model, review, update, and complete it on behalf of MMSD in order to expedite the analysis and permitting for the residents of Glendale.
Currently, the Hec-RAS model of the Milwaukee River from Hampton Ave to Good Hope Road has been completed and is undergoing review with MMSD. In the coming months, the model will be finalized and send to WDNR and FEMA for review and approval. After their review, FEMA will approve the preliminary flood maps prior to release of an official map revision for regulatory purposes. This process can be lengthy, depending on FEMA’s turnaround time. There will be several opportunities for public involvement and comment into the Map Revision process at that time. Stay tuned to the website for further updates as they are available.
