Overview

The E. Cedar Street Stormwater Improvement Project completes a multi-year plan to upgrade stormwater management in a four-block section of Downtown. The project involves upsizing and/or replacing some stormwater infrastructure along E. Cedar Street, from N. Walker Street to just west of Roger Alley and rerouting the flow to tie into an existing manhole to resolve legacy street flooding issues. Additionally, the Town will use a trenchless, point repair method at strategic locations to prevent water and soil infiltration, as well as use sealant to address leaks in other stormwater infrastructure. 

This is a collaborative effort that draws on public and private contributions, including the cooperation of CSX Railroad, which created additional design and construction requirements. This project will accommodate ongoing redevelopment of the corridor and ensure the stormwater system is fully functional and resilient for future uses.

Details 

The primary components of this project include:

• Upsizing and/or replacing storm pipe to increase capacity.
• In-situ rehabilitation of infrastructure immediately adjacent to CSX railroad, where replacement was not possible.
• Abandonment of storm pipes that conflict with existing private buildings and rerouting the flow to avoid impacts.

Schedule

Construction will begin on January 27, 2025, and is scheduled to be completed in Spring 2025. This section of E. Cedar Street will be closed during construction; however, access to all businesses will be maintained.

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 will be 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 upgrading aging stormwater infrastructure.

Schedule

This project began in Fall 2023 and is scheduled to be completed in Fall 2025. View the project schedule as a map below or on a full screen for easier viewing.

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 to be improved, 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:

• Prestonwood Tennis Aerial Sewer Stabilization - this project includes the support and stabilization of an existing sanitary sewer line adjacent to Prestonwood Tennis Club. This sewer line crosses a stream and has become vulnerable to impacts of stream bank erosion. Design will include reinforcing the pier supports for the sewer line and armoring the stream bank to prevent further erosion and potential risk to the aerial sewer line. This project is anticipated to begin in Spring 2025.

• 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 begin in Summer 2025.

Cary’s jurisdiction includes multiple facilities and Stormwater Control Measures. As owners of these devices, Cary pursues major repairs, retrofits and improvements as necessary. Examples of recent projects include the following:

• Old Apex Water Tower repair and retrofit. Cary’s bioretention cell located on Old Apex Rd. was constructed before the requirement for underdrains. As such, the device drained very slowly, and was holding water for longer than the allowable maximum time. This project included redesigning this device to include underdrains, and will replant with native pollinator plants. Currently, construction is complete with the exception of plantings, which will be installed in Spring 2025.
