Overview

Beginning January 2024, Cary will be dredging Symphony Lake, which will involve closure of a portion of the Symphony Lake Greenway and appropriate alternate pedestrian routes. The ultimate outcome is a more ecologically and environmentally sound as well as aesthetically pleasing public area for the enjoyment of Cary citizens. This work will be completed in Summer 2024.

Details 

The primary components of this project include:

• Dredging to remove accumulated sediment in Symphony Lake
• Transportation of the dredged sediment to South Cary Water Reclamation Facility
• Closure of the greenway during the project to ensure public safety
• Repaving of the greenway upon project completion

The below map shows the alternate pedestrian route while the project is ongoing. Please check back for updates as the route may change as the project progresses.

Schedule

Construction is anticipated to begin in January 2024 and scheduled to be completed in Summer 2024.

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

Construction is anticipated to begin in Fall 2023 and be completed by Summer 2024. View the project schedule as a map below or on a full screen for easier viewing.

Overview

This project addresses greenway erosion and ponding water in the Vickie Drive right-of-way by converting an existing ditch into a Biofiltration Channel (BFC).  This example of Green Stormwater Infrastructure (GSI) will provide an opportunity for the water to infiltrate while also slowing down the water coming off the roadways prior to discharging under the greenway that leads to the receiving stream channel. 

Details 

The primary components of the project on Vickie Drive include:

• Reworking the curb and gutter and installation of flume to capture the water off the road right-of-way
• Construction of cascading boulder step-pools and bioretention soil
• Installation of a stormdrain box structure that will allow for the underdrains to tie-in to the existing concrete pipe under greenway
• Repaving of approximately 150 ft of greenway

Schedule

Construction is anticipated to begin on May 6th, 2024 and scheduled to be completed in Summer 2024. This section of the Pirates Cove Greenway Connector trail will be closed during construction.

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

Construction is anticipated to begin in winter 2024 and is scheduled to be completed in winter 2025.

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.

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:

• Faculty Ave. Bioretention repair and retrofit. Cary’s bioretention cell located on Faculty Avenue in downtown Cary was experiencing slow drainage and not fulfilling its design requirements. This was due to the bald cypress trees in the device compromising the underdrains and preventing infiltration. Cary contracted with engineers to remove the existing trees, replace the underdrain system, and replant the bioretention cell with native pollinator plants.
• 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. Cary is currently in the process of redesigning this device to include underdrains, and will replant with native pollinator plants.
