YU & Associates, Inc. (YU) conducted the preliminary evaluation of drainage improvements for the purpose of troubleshooting the chronic flooding along Route 17 and the surrounding community in Lodi, NJ. This site was initially a part of the New Jersey DOT Statewide Drainage Study for Regions I and II, New Jersey. Services included an on-site investigation of existing surface condition, watershed delineations, storm drainage analysis, and the formulation of the preliminary recommendations to remediate the flooding. Additional services included an assessment of traffic accidents, environmental permits and clearance requirements.
Ultimately the New Jersey DOT Route (Rt.) 17 / Essex Street Drainage Project involved the construction of one mile of 10 and 11 ft diameter polymer-coated asphalt lined corrugated steel pipes with associated intake and outfall structures, and a pumping station with below grade chambers between Rt. 17 and the Saddle River in Lodi, New Jersey. The new construction provided a suitable outlet for drainage for the Rt. 17 / Essex Street widening project, and reduced the flooding conditions that occurred during most rainfall events along Rt. 17 at Gregg Street and an adjacent portion of Lodi creek.
YU also performed preliminary and final geotechnical studies of the project right-of-way and completed a preconstruction conditions survey of the existing structures that are in closed proximity of the right-of-way.
