Adam Street Drainage Improvements | City of Fayetteville

Gradient designs and implements comprehensive drainage solutions that address undersized infrastructure and mitigate flooding in low-lying, urban neighborhoods. Their experience with rerouting storm systems and upgrading water mains aligns with Raleigh’s stormwater management needs for major CIP projects.

Overview

This project was identified as a potential solution in the Cape Fear 2 (West) Watershed Study.

The existing 36-inch storm drainage pipe, which conveys runoff through the community and downstream to the Cape Fear River, was undersized, causing water to back up into the upstream systems and flood the neighborhoods on Link Street, School Street and Adam Street, as well as downstream areas.

The areas west of Eastern Boulevard (Link Street, School Street and Adam Street) are low-lying areas with no overland flow relief.

During more significant storm events, these low areas pond to a depth that impacts the roads and structures. This project diverts flow from the Link Street, School Street and Adam Street areas west to Blount’s Creek, thereby reducing the flooding in these areas and diverting flow away from the downstream areas.

This project involved installing a new storm drainage system along Adam Street. A portion of the existing storm drainage system was removed, replaced with a 36-inch diameter concrete pipe, and rerouted to the west to an eventual discharge into Blount’s Creek, an approximate distance of 1,000 LF.

As part of this project, the existing 6-inch diameter water main within Adam Street was replaced with 1,250 LF of a new 8-inch diameter main.
