Chandworth Storm Drainage Improvement Project
This project involves planning analysis of improvement alternatives and design and construction of needed improvements. The project area is bordered to the west by Park Road, to the north by Conservancy Lane, to the south by Ashton Drive and to the east by Brookfield Drive. This is the second project to be started which was phased from the Sunnyvale/Chandworth watershed area to align scope with available funding. This project is within a subbasin of 200 acres inside a total watershed drainage area of 690 acres. The improvements will include culvert replacements, pipe system upgrades and channel improvements.

The need for this project was identified through a project ranking process that involves analysis of customer drainage requests, including complaints of house (finished floor) flooding and road flooding. Previous maintenance work has been done within this project area to help alleviate flooding to some of the more problem prone areas. This project will improve the storm drainage infrastructure in order to reduce flooding of streets and structures.

Planning was completed in conjunction with the Sunnyvale Chandworth project.  

Sunnyvale/Chandworth Project   


- Update and improve the capacity and performance of the drainage system in the project area to reduce flooding of streets, properties, and structures and stabilize streams.
Cost: $11,100,000 
Please note that this figure includes all costs associated with the project such as planning and design, utility relocation, consultant fees, construction, permits and landscaping.

The Charlotte-Mecklenburg Storm Water Services (CMSWS) project team will manage the Chandworth Project through the phases listed below.

A general description and range of typical timeframes for project phases is given below. Specific work is conducted during each phase while an emphasis is made on public involvement throughout the entire project.

Planning Phase (June 2013 - November 2013)
During the planning phase, public meetings are used to obtain input from property owners. Several improvement alternatives are developed and evaluated to determine the best solution. A recommended alternative is presented to the public for comment at the end of the planning phase. The planning phase of a project typically lasts 12 to 27 months.

Design Phase (Started January 2014)
During the design phase, construction drawings are developed for the alternative selected during the planning phase. Many details must be addressed including the determination of channel widths and lining types, utility relocations, and easement locations. The design phase of a project typically lasts 21 to 34 months.

Permitting Phase (Time frame TBD)
During the permitting phase, the required water quality permits are obtained from Federal and State governments. Other permits such as permission to work within railroad and NCDOT rights-of-way may also be obtained during this phase if necessary. The permitting phase of a project typically lasts 3 to 9 months; however, it may overlap other phases.

Property Easement/Acquisition (Time frame TBD)
The City's real estate staff works with citizens and businesses to acquire either Conservation Easements or Storm Drainage Easements. In addition, temporary construction easements may also be needed to access work areas. The City requests that easements be donated to provide access to your property to make the recommended improvements and provide future maintenance. The bid phase will begin after all easements are acquired. The easement acquisition phase of a project typically lasts 8 to 12 months.

Bid Phase (Time frame TBD)
During the bid phase, the final plans will be circulated to qualified contractors for a competitive bidding process. By state law, the lowest responsible bidder is awarded the construction contract. The bid phase of a project typically lasts 5 to 6 months.

Construction Phase (End by Spring 2021)
Throughout construction, efforts will be made to minimize disruption to nearby property owners. Construction of proposed improvements will be supervised by City inspectors. Notifications of key construction dates will be mailed to residents prior to construction. The construction phase of this project can last up to 2 years.
