The Morningside D&E Neighborhood Roadway Reconstruction project in Edina, Minnesota, embarked on a significant transformation in 2022, extending through 2023. This multifaceted endeavor entailed a comprehensive overhaul of the local infrastructure, encompassing the replacement of asphalt pavement, concrete curb, gutter, and sidewalks, as well as upgrades to fire hydrants and water main gate valves. Notably, a significant aspect of this project involved enhancing the sanitary and storm sewer systems to mitigate flood risks, thereby ensuring the safety and resilience of the local community.
The City of Edina encountered the challenge of selecting the most suitable materials for the crucial improvements to the storm sewer system. After meticulous evaluation of various alternatives, including reinforced concrete pipe (RCP), steel reinforced polyethylene (SRPE), and polypropylene (PP), the city authorities ultimately selected DuroMaxx® SRPE, manufactured by Contech Engineered Solutions.
DuroMaxx® SRPE with HP Joint was chosen for its substantial cost savings as well as inherent characteristics, making it the perfect match for the demanding requirements of this storm sewer enhancement project. The specified diameters, 72-inch and 60-inch, coupled with a total length of 882 linear feet in convenient 14-foot segments, ensured a seamless fit within the project's scope. Moreover, the incorporation of 48-inch risers, complemented by their associated fittings (a total of 6 units), further bolstered the system's integrity.
The selection of DuroMaxx® SRPE brought substantial advantages to the Morningside D&E Neighborhood project. Notably, it outshone competing materials, not only in terms of the total time required for installation but also in its remarkable adaptability to conform to the specific site plans, making the construction process remarkably efficient. This adaptability ensured that the storm sewer improvements integrated seamlessly with the broader reconstruction efforts, reducing disruptions to the local community.
In a strategic cost-saving move, the City of Edina also opted for pre-manufactured riser fittings in lieu of traditional precast manholes. This decision not only reduced expenses but also expedited the project's timeline, contributing to the overall success of the storm sewer system upgrade.
The Morningside D&E Neighborhood Roadway Reconstruction project in Edina, Minnesota, stands as a testament to the City's commitment to enhancing the resilience and reliability of its infrastructure. By selecting DuroMaxx® SRPE with HP Joint and embracing innovative solutions like pre-manufactured riser fittings, the City of Edina has not only addressed immediate flood risk concerns but has also invested in a sustainable, long-term solution that will serve the community for years to come. This successful case study underscores the vital role of advanced materials and prudent decision-making in infrastructure development and the long-term well-being of the community.
