To meet the growing needs of the West campus of the Texas Medical Center and the Energy Corridor, Western International purchased land at the corner of Barker-Cypress Road and Park Row to build a 135 room, 20,854 SF Hampton Inn Suites.
A stormwater management system was needed to manage stormwater from the roof, parking lot, and other impervious surfaces. The site was in an urban environment, so there was no space for a land based stormwater BMP. Therefore, the engineers designed an underground detention system located beneath the parking lot.
Engineers were limited by the depth of the existing stormwater outfall. They also had to contend with clearing other utilities. A number of materials were considered for the detention system including concrete vaults, HDPE pipe, and corrugated metal pipe (CMP).
After evaluating material options, a CMP system from Contech Engineered Solutions was chosen. CMP was more economical than concrete, and it had a smaller footprint than HDPE. Contech provided 4,482 linear feet of 48" diameter Aluminized Steel Type 2 that was used to create two detention systems that were placed underneath the parking lot and surrounded the building on three sides.
The CMP detention system was installed in November of 2014 and the hotel will open in the summer of 2015.
