Cary is undergoing an update of its Stormwater and Watershed Protection Master Plan, which was last updated in 2013. The goal of this project is to update the plan with current operations, regulatory requirements, capital improvements and potential future financing options.

This project began in 2025 and is anticipated to be complete in 2026.

Overview

This project seeks to inspect and assess stormwater infrastructure in Cary's right-of-way, deeded easements and on Cary property using Closed Circuit Television. Cary has contracted with Vision NC to inspect approximately 73,000 feet of stormwater pipes and structures. Staff will use this information to prioritize infrastructure assets to repair or replace.

Details 

The assessment area is from Chatham Street to Old Apex, Maynard and Kildaire Farm Road areas. Vision NC trucks will temporarily stop along these roads while they conduct the assessment, but no road closures are anticipated. Pipes assessed will be cleaned as needed, inventoried and given a ranking score for future prioritization. This project continues Cary's commitment to assessing and maintaining stormwater infrastructure.

Overview

This project addresses area drainage and flooding issues by replacing aging stormwater infrastructure at Lake Pine Dr. and adding a culvert along Brookgreen Dr. Taking safety and traffic flow into consideration, these sites will be under construction one after the other, not simultaneously. 

Details 

The primary components of the project on Lake Pine Dr. include:

• Removing six metal pipes
• Adding two larger box culverts to better align with the stream channel
• Reinforcing the stream channel immediately below the culvert

The primary component of the Brookgreen Dr. site is installing an additional culvert. 

This project continues Cary's commitment to upgrading aging stormwater infrastructure and addressing drainage issues to further protect our community from the impacts of flooding. 

Schedule

The Town is in the process of acquiring necessary easements in the project area; construction will be scheduled after this acquisition and when environmental permits have been approved.

Cary’s Departments of Public Works, Utilities, and Transportation have a range of projects throughout Cary’s jurisdiction to update, improve, and retrofit existing infrastructure. As projects in other departments are underway, the Stormwater Division assesses whether there are needed stormwater improvements in the area, and schedules the work to occur at the same time. This is to prevent additional disruption to our citizens and accomplish multiple goals in one project.

Current projects include:

• Pond Glen Way Sewer Easement Stabilization - this project will address erosion and reduce risk to an existing 18" sanitary sewer pipe in the area of Pond Glen Way and Gingergate Drive. A number of small channels parallel to a stream have begun to erode the surrounding area and expose the pipe. To address this risk, the upslope area of the stream will be regraded, erosion will be repaired and flow will be rerouted into two new channels to protect the sewerline. This project is anticipated to be finished in Spring 2026.

Cary’s jurisdiction includes multiple facilities and Stormwater Control Measures (SCMs). As owners of these devices, Cary pursues repairs, retrofits and improvements as necessary.

• Page Walker Drainage Improvement - this project will address structural flooding  in the basement of the historic Page Walker building. This project is still in the planning phase.

• Garmon Operations Center Stormwater Wetland - one of the regulatory SCMs at this facility requires repairs to the outlet pipe. Deterioration of the corrugated metal pipe requires the installation of a UV liner. The contract for this project has been awarded and construction is anticipated to begin in Spring 2026.

• 113 Palace Green Open Space Acquisition & Preservation - Plans have been developed to demolish this residential structure and preserve the floodplain open space. This area will be replanted with native trees and shrubs. Demolition is anticipated to occur in Spring/Summer 2026.
