The Northeast Drainage Ditch crosses Lonnbladh Road, a minor collector, and causes flooding in the road on an adjacent property several times a year.

Genesis designed the improvements to the channel crossing and the downstream conveyance to significantly reduce the frequency of flooding. The improvements included removing two severely undersized corrugated metal pipes and installing a triple 4’x 8’ box culvert under the road. A new conveyance was constructed lower and parallel to the existing drainage ditch to meet the demand of the 25-year storm event without overtopping Lonnbladh Road and minimizing the impact to the surrounding wetlands. The existing ditch remains and still functions in normal low flow conditions so as to preserve the integrity of the natural conditions and wetland features.
