Grottoes, Virginia, a town of 2,600, has the usual complement of underground infrastructure that make any town work, and in 2013 one significant asset, a large stormwater system, was in trouble.
The Virginia Department of Transportation (VDOT) gives the town funds for the maintenance of streets and stormwater networks, and as part of that arrangement, VDOT requires the town to conduct annual inspections. In the last report, a large set of elliptical CMP culverts didn’t pass inspection. “Our consultant, Schwartz & Associates, told us the culverts were in poor condition,” explains Grottoes Town Manager Jeff Nicely. “They said there was severe corrosion, and that individual sections were failing and misaligned. They recommended replacement."
