Shamrock Gardens Storm Drainage Improvement Project

This project involves addressing a deteriorated corrugated metal pipe system located within the Shamrock Gardens Apartment complex as well as reducing flooding of multiple roadway crossings. An analysis of existing conditions will be performed to determine portions of the storm drainage system needing improvement, planning analysis of improvement alternatives, and design and construction of needed improvements. The Shamrock Gardens Storm Drainage Improvement Project is bordered by Purser Drive to the north, Shamrock Drive to the south, Briar Creek to the east and Eastway Drive to the west. This project is within a drainage area of approximately 75 acres and the improvements may include culvert replacements, pipe system upgrades and channel improvements.

Cost:  To Be Determined (TBD)
Please note that this figure will include all costs associated with this project such as planning and design, utility relocation, consultant fees, construction, necessary permitting and landscaping. ​​

​The Charlotte-Mecklenburg Storm Water Services (CMSWS) project team will manage Shamrock Gardens 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.  Public meetings will be held throughout the project with the affected property owners to present the planning and design information and receive input.

Planning Phase (Started March 2014)
During the planning phase, citizen and public meetings are used to obtain input from property owners and residents. 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.

Design Phase (Time Frame TBD)
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 storm drainage pipe sizes and alignments, utility relocations, easement locations, and traffic control logistics. The design phase of a project typically lasts 21 to 34 months.  Due to an accelerated schedule on this project we expect the design phase to last 12 to 24 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 easement acquisition phase of a project typically lasts 8 to 12 months.

Bid Phase (Time Frame TBD)
The bid phase will begin after all required permits are obtained and all easements are acquired.  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 (Time Frame TBD)
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. Due to the size of this project, the ​construction phase can last from 12 to 18 months.
