EDINA PUBLIC WORKS FACILITY
Edina, Minnesota
Project type: Adaptive reuse
Size: 138,000 square feet
Completion: 2010
This building and site were chosen after years of looking for suitable sites. Edina has limited real estate available for such large projects, but the previous inhabitants operations were of a large enough scale that the existing buildings and site layout were reasonably cohesive with the Public Works plans. Tearing the existing building down was debated, but it was decided that the least environmentally friendly option would be to “tear down a block building and replace it with another block building.” Essentially we took an old popcorn factory and turned it into a public works building.
The 138,000 square foot facility includes renovation to an existing building and additions to the former popcorn factory. The facility is not LEED certified, as city council could not justify the expense, but LEED principles were followed. Numerous energy conservation strategies were studied and implemented into the building and site, including a geothermal system.
Innovative stormwater treatment techniques were employed to address environmental concerns. Specifically, two rock infiltration treatment trenches measuring 300 feet by 4 feet by 3 feet were installed, providing effective water quality control without occupying a significant footprint. These trenches were strategically placed around the newly constructed geothermal field system and piping network within the parking lots. Additionally, a thoughtfully designed stormwater treatment pond was created to facilitate additional infiltration, sediment removal, and stormwater runoff rate control. The design of the pond took into account the preservation of mature pine trees and other existing landscape features on the site, ensuring minimal disruption to the natural environment.
The final result is a transformed popcorn factory, now serving as an efficient and environmentally conscious public works facility. Though not LEED certified, the project incorporated sustainable principles, demonstrating a commitment to responsible construction practices and showcasing innovative stormwater management solutions.
