The Warren Street Flood Risk Reduction project will improve the drainage system in the area along Exposition Blvd., Warren St., Carlton Road, Mount Laurel Lane and Hillview Road in the Tarrytown neighborhood.


Watershed Protection Department has received several local flooding complaints from residents in this area. Local flooding is the type of flooding that generally occurs away from the creek. It occurs due to an undersized or lack of local drainage system The project is intended to alleviate the flooding of buildings, yards, and streets through upgraded and/or new storm drain infrastructure. Currently the project is in Preliminary Engineering Phase, which evaluates different alternatives to reduce flooding risk in the project area.

Our capital improvement projects take many years from start to finish. The process typically includes the following phases:

  • Preliminary Engineering – when a solution is identified and costs are estimated.
  • Design – when the details are worked out and construction plans are drawn up.
  • Bidding and Permitting – when a contractor is hired and all permits are acquired.
  • Construction – when the project is built.

The project is currently in the preliminary engineering phase.
