Essex Court Area Drainage Investigation Town of North Hempstead Department of Public Works
LiRo-Hill performed survey, design, and construction inspection services for approximately 0.8 miles of this residential area of Port Washington. The area was repeatedly flooded due to a high water table and underground streams. A complete drainage study of existing conditions, generation of a drainage master plan, design of drainage improvements by mitigating inadequate and sub-standard conditions, and a hydrological evaluation of the proposed system were conducted. French drains were connected into a positive drainage system to prevent flooding and wet conditions. The project also included the reconstruction of pavement, concrete curbs, driveway aprons, and sidewalks, and pavement markings. Due to the limited options available for entering and exiting the court neighborhood, precise MPT considerations were maintained throughout construction.
