Cohocksink Storm Flood Relief Project: Phase 6

Overview

Project #40736 Cohocksink Storm Flood Relief Project: Phase 6 is a planned PWD project in the Olde Kensington/Northern Liberties neighborhoods.

The work will double conveyance capacity of the combined sewer system through the construction of new sewer and stormwater infrastructure in these flood-prone commercial and residential neighborhoods.

This project will reduce the risk of flooding while enhancing community amenities. It includes 1,600 feet of new box sewers, new water mains, sewers, and green stormwater infrastructure, and utility, street, and sidewalk repair.

Construction Details

Construction contact information, expected work dates, and streets affected is listed below. During construction, an assigned PWD inspector and engineer will be on-site and can answer questions about the work.

For more information, please email the PWD community outreach team at water.projects@phila.gov. Please specify the project name, project number, and ZIP code in your email.

Project Benefits

• Reduced risk of sewer backup in basements
• Reduced combined sewer overflow, groundwater seepage, shallow street flooding, and building flooding across a large rapidly developing drainage area
• Rebuilt sidewalks, curbs, and streets restoration; new bike lane routes; and green streets infrastructure to reduce flood risk
• Protection of critical utility buildings, a school, a recreation center, and a medical facility

Project #40736 is the final phase of a six-phase flood mitigation project (previously called the Northern Liberties Flood Relief Project). Since 2004, the Northern Liberties, Ludlow, and South Kensington neighborhoods have been heavily impacted by an increasing number of intense rain events.
