Five Factors Influencing Underground Detention

Recently, a Hixson client wanted to expand their building over an existing parking lot, and then to convert an existing detention pond into a parking lot to re-gain those lost spaces. This required the conversion of conventional aboveground detention pond to an underground detention system below the relocated parking lot.

In this issue of Hixson’s Building Experience newsletter, we look at the five things you need to know about underground detention systems.
