A River Runs Through It: Stormwater Design at VMI, Part 2

The project site for the Corps Physical Training Facility at VMI presented the design team with a unique stormwater design challenge, which allowed for several creative solutions to minimize the stormwater impact of construction. The development of the site converted an area that had previously been mostly open space into a highly developed site, which without proper stormwater controls would cause a substantial increase in runoff as well as water-borne pollutants. To mitigate this, the project included installation of many stormwater practices including: bioretention, a green roof, permeable pavement, underground detention, a rainwater harvesting system, and several manufactured BMPs....

A River Runs Through It: Stormwater Design at VMI, Part 1

The new Corps Physical Training Facility at VMI in Lexington, Virginia was completed in 2016 and houses two indoor tracks as well as other training features such as a high ropes course, climbing wall, and cardio equipment. The project’s location along Main Street in Lexington provided several unique challenges, including the existing Town Branch creek that runs beneath the new building. Because of past floods along this section of the creek, the design team developed a flood model to both guide the elevations of the proposed building and ensure that the proposed construction would not make flooding worse. [caption id="attachment_6495" align="aligncenter" width="770"] Flooding of Town Branch along Diamond Street in 2012[/caption] To account for potential flooding, the entire building is elevated above the creek level so that a 100-year storm can pass below without causing flood damage. The first level of the new facility is dedicated to parking, so that if a...
