Flood Insurance Rate Maps (FIRM) are the official maps produced by FEMA and adopted by the City of Wauwatosa in 2008. Please note that these maps have not yet been updated to reflect the Hart Park Flood Improvement project or the County Grounds retention basins project. The City is working with various local, state, and federal agencies to update the maps to reflect these projects.
To determine is your property is located within a floodplain, please contact the Planning Office at City Hall or the FEMA Map Service Center via the link below:

Letter of Map Change (LOMC)
A LOMC is a document issued by the FEMA, that amends or revises the flood insurance rate maps (FIRM). There are a few types of LOMCs:
• LOMA (Letter of Map Amendment) - These are letters issued by FEMA that identify if a specific structure is located in the floodplain based on submitted elevation data. These are the most common type of LOMCs issued. These letters do not formally change the maps but the FEMA issued letter supersedes the maps.
• LOMR-F (Letter of Map Revision Based on Fill) - These are letters that formally modify the floodplain boundaries for a certain area. These are used when fill is being placed within the FIRM mapped floodplain.
• LOMR (Letter of Map Revision) - These are letters that formally modify the floodplain boundaries (floodfringe and/or floodway) for a certain area and typically involve a new study being done for a certain area. These take a bit more time and have a larger expense associated with them than LOMAs.
If a property owner thinks their property has been inadvertently mapped in a Special Flood Hazard Area, they may submit a request to FEMA for a Letter of Map Change. If the LOMC request is granted, property owners may be eligible for lower flood insurance premiums, or the option to not purchase flood insurance
