Project Description

The Old Greenwich Storm Drain Improvements project is a culmination of approximately 10 years of planning, analysis, and design to alleviate flooding and restrictions to emergency services in and around the Old Greenwich downtown area. The project involves the installation of storm drain structures and pipes on:

  • Highview Avenue
  • In the Vicinity of the Old Greenwich School and on School Property

The Contractor, Grasso Companies, LLC, Norwalk, CT, has resumed working on the final phases of the project between 7 a.m. to 6 p.m., Monday through Friday.

The remaining work began at the beginning of April 2018 and is anticipated to last approximately 6 to 8 months, with pipe installation between Spring 2018 and Summer 2018 and final restoration occurring in Fall 2018.
