Project Description

To alleviate sewage back-ups and flooding in the drainage area, the proposed project involves dredging the former Queen Ditch, cleaning out the twin culverts, and constructing a box culvert from the existing diversion chamber to the proposed Queen Ditch inlet. The 108-inch wide by 60-inch high by 460-foot long precast concrete box culvert will be installed in the same footprint as the former Queen Ditch and currently an asphalt parking lot bordered by vegetation on two sides. This underground box culvert will traverse the asphalt parking lot and a swath of grass on one side and light vegetation on the opposite side. The parking lot and vegetated areas will be temporarily disturbed by excavation activities to install the culvert; subsequently, the parking lot will be repaved and surrounding soils will be graded and replanted with grass as part of restoration. Additionally, a 12-foot wide by 22-foot long by 6-foot high netting facility followed by a 9-foot high by 5-foot wide tide gate will be installed at the end-of-pipe to transition from the new box culvert to the drainage ditch inlet. This combined structure will capture trash and floatables from overflows during wet weather events and prevent backflows.
