Williston Basin Flood Study

The Williston Basin Tributary is approximately a 110-acre depressional watershed that is generally bounded by Prospect Avenue to the east, Liberty Drive to the north, Chase Street to the west, and Roosevelt Road to the south. The watershed contains multiple depressional areas that cause overland flooding into homes during large rain events.

In early 2012, V3 Companies was contracted to complete a hydrology and hydraulic analysis of the area. The purpose of this study was to determine which residential structures were at risk of overland flooding. The area was surveyed and modeled, and the extents of this study can be found below. An alternative analysis was not performed during this study, but one is planned for a future date.
