A stormwater detention system with the ability to hold up to seven acre-feet (more than two million gallons) of storm water is being installed at the Cannon Drive Relocation – Phase 2 site.
Crews start by digging out the site and preparing the sub-grade. Next, geogrid is placed in the base stone, followed by installation of Storm Traps. Once complete, the system will temporarily store runoff underground before releasing it at a controlled rate to avoid flooding and other effects of stormwater runoff.
As Storm Traps continue to be loaded onto the site, Tom Ekegren, Facilities Design and Construction (FDC) project manager of Cannon Drive Relocation- Phase 2 said crews are installing sections of the system to reduce the amount of time the subbase is exposed to weather.
“Hundreds of trucks are bringing in different equipment daily,” said Ekegren. “We have safety plans in place and we also ask drivers and pedestrians to follow the instructions of signage and be aware when nearing construction zones.”
The system will help with the 500-year flood protection for the Columbus campus and meets the intent of the city of Columbus’ design manual.
