The goal of the Lafayette St. Underpass at Subway Pump Station (Project) is to assess, evaluate and recommend improvements for the constant ponding of groundwater through investigating the existing roadway, drainage systems, and the SWPS. The consultant will conduct the necessary field investigations and analysis in order to prepare reports that assess this infrastructure. This includes recommending improvements to address the constant ponding of water on the roadway and improvements to the SWPS. The reports will be used as the basis for the next phases of the project which include design and construction.
