Apollo High School, named after the Apollo Space Program, has been a part of Owensboro, Kentucky, since 1969. The school has undergone significant transformations over the years, including the recent construction of a new, $10 million Apollo High School stadium and parking lot renovations.
American Engineers were able to maximize the available space by using underground detention versus the traditional above ground basin. By utilizing underground detention, the school was able to gain parking spaces while meeting the stormwater detention requirements below ground.
Engineers determined the Terra Arch system was the best fit because of its low cover height requirement of 12” from the top of the arch to final grade. The fiber-reinforced concrete design and load-bearing rating of HS-25 gave the designer and owner a comfort level that it could handle the vehicle loads even with the minimum cover requirements. Terre Arch also minimized the footprint, as the stone backfill could be used for storage volume.
Eighteen Terre Arch 26 chambers and four manifold sections were installed, providing approximately 7,000 SF of storage. A Contech Field Consultant was on-site to guide Hazex Construction on the proper installation of the Terre Arch System, and installation was completed in less than one day.
