The purpose of the East Providence Project was to mitigate house and road flooding. Armstrong Glen provided surveying, hydrologic and hydraulic modeling, and designed storm water system upgrades to mitigate house and road flooding for a 275 acre watershed comprised of residential land use. The project included 3700 linear feet of open stream channel, seven roadway culverts, 50 driveway culverts and 7000 linear feet of roadside ditches. Although it began as a flood control project, Charlotte Storm Water Services targeted the East Providence Project as having potential to be a water quality improvement project.
Extensive channel work, along with upsizing road culverts, was required to mitigate house flooding. In an attempt to minimize channel erosion and recreate the natural stream environment, we integrated natural channel design techniques, including bankfull benches and in-stream rock structures, into the overall channel improvements.
Construction was completed in November of 2005. Construction cost was $2,200,000.
