McKenna Blvd/Gammon Ln Flood Mitigation Project

Last Updated: 06/21/2018

The east Park Edge Dr neighborhood consists of several cul-de-sacs that back the City of Madison's West Badger Mill Creek - Elver Park Greenway. That greenway carries water from Greentree Pond north of the neighborhood and discharges via pipes under McKenna Blvd to Elver Park. The associated watershed is approximately 1.4 square miles in area, and drains from north to south.

Since 2016, Park Edge Dr residents have noted several rain events in which water from the greenway flooded the neighborhood and entered their structures. Additionally, McKenna Blvd, which is a main thoroughfare through the neighborhood and houses police and fire stations for the west side, has overtopped and become impassible several times. As such, City Engineering is proposing a public works improvement to fix this issue. The City is looking at design options, which may include a project that would lower the overflow elevation in Elver Park, which should reduce flooding in the Park Edge neighborhood and lower the flood elevation on McKenna Blvd itself. The potential design could include some road work along McKenna Blvd and parking lot reconstruction and grading in Elver Park.
