MMSD has scheduled an Open House on June 11 from 4:30 - 7:00 pm at the Hart Park Muellner Building to share information and answer questions about upcoming levee system improvements in the Hart Park area. MMSD has been designing levee improvements to meet FEMA levee standards. Improvements are scheduled for construction in 2026 and 2027 and include raising the levee along River Parkway and 63rd Street, raising the floodwall along Hart Park Lane, several storm sewer improvements, and tree removal near the levee to meet standards. The planned work areas are shown in this map.
As part of the planned construction, MMSD has partnered with the City of Wauwatosa, which has provided additional funding to improve a MMSD levee maintenance drive to create nearly 2,000 feet of recreational trail near River Parkway and 63rd Street.
MMSD reviewed the entire levee system and identified improvements required for the system to be accredited FEMA. Improvements include adding additional height to levees and floodwalls at several locations, storm sewer improvements, and sewer rehabilitation.
For FEMA to recognize the completed levee system's flood risk reduction benefits requires a levee system accreditation application to FEMA for the entire Menomonee River levee system. Once FEMA approves a levee system application, remapping the floodplain in the surrounding project area can proceed.
The FEMA review process is expected to take up to three years. Some structures will remain in the mapped floodplain after the levee system is completed. These structures remaining in the floodplain will be evaluated for other flood risk reduction approaches, such as voluntary floodproofing and voluntary acquisition.
Ahead of the levee system accreditation submittal to FEMA, MMSD has reviewed FEMA standards for the entire system and has identified several improvements to the system that are required for the system to be accredited.
The levee system improvements are needed for the following reasons:
