Project Background

The purpose of this project is to relieve basement sewer backup risk, reduce street flooding, and overall risk to the large sewer trunk in the project area. To that end, this project will upsize or repair portions of the public sewer main line to increase its capacity to handle combined sewer and stormwater. It will also build green street planters that help slow, filter, and cleanse stormwater from the streets.   

The project is designed to accomplish the following sewer and stormwater improvements:  

  • Replace or repair 9,000 feet of public sewer mainline pipe, ranging in size from 8 inches to 21 inches in diameter.
  • Construct or replace 228 sewer service connections (laterals) that connect private sewer lines to the public sewer in the street; this will involve 3,700 feet of lateral sewer pipe. 
  • Install almost 800 feet of pipe for storm drains.
  • Install or replace 137 storm drains.
  • Construct 25 green street planters.
  • Construct or replace 137 maintenance holes.
  • Construct 44 ADA ramps.
