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.
As of January 2020, the MMSD has completed preliminary modeling and mapping of the floodplain from approximately Hampton Ave to Good Hope Road. Additionally, a large surveying effort of nearly 100 properties has been completed by MMSD and incorporated into the model to help assist with more accurate floodplain boundary delineations.
Currently, MMSD is working to prepare preliminary maps by finalizing the 100-year floodplain limits and modeling 500-year floodplain limits to be added to the maps.
Once this is complete, the maps will be prepared and made available for review by the City of Glendale staff. At that time, the City will work alongside MMSD to submit paperwork to DNR and FEMA.
After their review, FEMA will approve the preliminary flood maps prior to release of an official map revision for regulatory purposes. The estimated completion date from MMSD at this time is Spring 2021. There will be several opportunities for public involvement and comment into the Map Revision process.
Please stay tuned for updates as they become available or use the information above to contact with any questions.
