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 October 2018, the MMSD has completed preliminary modeling and mapping of the floodplain from approximately Hampton Ave to Good Hope Road. Currently, they are undergoing a large surveying effort of nearly 100 properties. These surveyed elevations will help provide the most accurate depiction of the floodplain limits. It is anticipated that this survey effort will last several months.

Once the survey efforts are complete, preliminary maps will be prepared and made available for review by the City of Glendale staff. It is anticipated that these maps will be released in December 2018. At this 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. We cannot estimate a time-frame for the release of the revised maps at this time. There will be several opportunities for public involvement and comment into the Map Revision process.

Update May 6, 2019:  The City of Glendale has received and is currently undergoing review of the preliminary modeling information developed by MMSD.  The information provided relates to the 100-yr Special Flood Hazard Areas (SFHA) floodplain only and does not yet include the 500-year floodplain, nor delineation of the 100-year floodway.  Currently, our review will take at least two weeks and we will be working very closely with the MMSD throughout this draft process.  Once the City's review is completed, the modeling will be forwarded to the Wisconsin Department of Natural Resources (WDNR) for review and comment, followed by review and approval by FEMA.

Please note that the City, in conjunction with MMSD, will determine a time to present this information to the residents.  A date and time has not yet been established.

Please stay tuned for updates as they become available or use the information above to contact with any questions.
