A multi-phased, fiscally responsible investment to mitigate flooding, improve water quality, stimulate investment, and enhance quality of life within the Bee Branch Watershed.
A watershed is an area of land that drains to the same place. Dubuque's 6.5 square mile Bee Branch Watershed drains to the Bee Branch Creek and is located entirely within the city limits. This watershed area includes the city’s most developed areas where over 50% of Dubuque residents either live or work. The watershed encompasses historic neighborhoods offering some of the community’s most affordable workforce housing. This area is also hit hardest by flash flooding during significant rain events with much more than “just a little water in the basement.”
Too frequently, it is flooding that inundates water heaters, furnaces, and electrical boxes, and can cause fires. It rushes down streets from curb to curb -- stalling vehicles, stranding motorists, displacing manhole covers, and damaging pavement, water mains, and stormwater and sanitary sewers.
Mayor Roy D. Buol and the Dubuque City Council have made infrastructure projects a high priority and they are committed to the Bee Branch Watershed Flood Mitigation Project, a multi-faceted approach to addressing the severe and frequent flash flooding experienced in the watershed. This project consists of 12 phases. The combined phases will reduce the volume of stormwater, slow the rate of stormwater through the upper watershed, increase the safe conveyance of stormwater through the flood-prone area, and provide floodwater protection to the City’s water treatment plant on Hawthorne Street.
In early December 2013, the project was awarded $98.5 million from the Iowa Flood Mitigation Board in the form of state sales tax increment financing spread over the next 20 years. When combined with other state and federal grants and local donations, the City has received over $127 million to help fund the $179 million project. Additional funding sources are being explored.
