PROJECT Rhomberg Avenue Bridge Upper Bee Branch Creek Restoration Project bridges community, creativity, and collaboration by Michael A. Jansen, IIW P.C. When the city of Dubuque, Iowa, launched its flood mitigation project— the largest capital improvement project in the city’s history—residents and the city focused on how a watershed solution could also serve as a catalyst for neighborhood reinvestment and revitalization. Through many public meetings, it became clear residents were not only concerned about eliminating devastating flooding, but they wanted amenities that would support a sustainable neighborhood with enhanced quality of life. This flood mitigation project will protect over 1300 homes and businesses. The project has the added value of improving water quality and property values, stimulating investment, and enhancing quality of life. The Bee Branch Creek Restoration project takes former industrial, commercial, and residential properties and creates an open waterway with a linear park—complemented by a highly visible bridge, culvert, and overlook structures, recreation green space and trail, outdoor amphitheater, community orchard, and playground equipment. The Lower Bee Branch Creek segment includes a channel connected to a large expanse of open water that wraps around a former industrial site. Construction of the Lower Bee Branch Creek started in the fall of 2010 and was completed in November of 2011. The Upper Bee Branch Creek segment, currently under construction, will have a 2300-ft-long landscaped creek and green space that accommodates low intensity recreational use. Community Expectations In August 2003, the Dubuque City Council formed a committee to study the flooding issues in the North End and Washington Street neighborhoods. To help the committee evaluate solutions, they established six criteria, including preservation of local businesses and services, minimization of property acquisitions, affordability, preservation of neighborhood access and connectivity, minimize health and safety risks, and minimize impacts to quality of life and the environment. The city council moved forward with the recommendation to create an open channel by day-lighting the Bee Branch Creek. In the fall of 2008, the design for the Bee Branch Creek Restoration was initiated. In order to understand the community’s vision for the project, the design team held a series of PROFILE RHOMBERG AVENUE BRIDGE / DUBUQUE, IOWA BRIDGE DESIGN ENGINEER: IIW P.C., Dubuque, Iowa PRIME CONTRACTOR: Tricon Construction, Dubuque, Iowa BRIDGE SUBCONTRACTOR: Jim Schroeder Construction, Bellevue, Iowa STAMPING SUBCONTRACTOR: D&D Superior Concrete Construction, Dubuque, Iowa PRECASTER: Crest Precast Inc., LaCrescent, Minn.—a PCI-certified producer
