6th and Graham Storm Drainage Improvement Project
This 6th and Graham Storm Drainage Improvement Project (SDIP) was started due to storm drainage structures that have been found to be in poor condition and flooding reported near the intersection of 6th Street and Graham Street. This project involves analysis of existing conditions to determine portions of the storm drainage system needing improvement, analysis of improvement alternatives, design of the improvements, and then construction of needed improvements. The 6th and Graham SDIP is bordered by I-77 to the northwest, 10th Street to the northeast, N. Tryon Street to the southeast, and Trade Street to the southwest. This project is within a drainage area of approximately 200 acres and the improvements may include culvert replacements, pipe system upgrades, and channel improvements. The project area is shown on the attached map.


Estimated Cost: To be determined (TBD)
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 6th and Graham SDIP through the phases listed below.

Planning Phase (Started June 2013)

During the planning phase, the existing conditions are assessed, beginning with aerial and ground survey. After existing conditions are evaluated several improvement concepts (alternatives) are then developed and evaluated to determine the best solution. A recommended alternative is selected and used as a guide for the design. This is shared with the residents in public meeting.

Design Phase (Time Frame TBD)
The engineering consultant works closely with Storm Water Services to develop the design. Personnel from City of Charlotte, the engineering consultant, land surveyors, wetland specialists, and geotechnical engineers work in the area collecting information necessary to complete the design.

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 CMU rights-of-way will be obtained during this phase. The permitting phase of a project may overlap other phases. Permitting phase typically lasts 3-9 months.

Property Easement/Acquisition (Time Frame TBD)
The City works with citizens and organizations to acquire Storm Drainage Easements (SDEs), Access Easements (AEs) and Temporary Construction Easements (TCEs). The City requests that SDEs, AEs, and TCEs be donated to provide the City access and certain rights to the affected properties to make the recommended improvements and provide future maintenance.  

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 (Time Frame TBD)
Throughout construction, efforts will be made to minimize disruption to nearby property owners. Construction of proposed improvements will be supervised by a City Inspector. Notifications of key construction dates and will be mailed to residents prior to construction. Construction involves earth work, concrete work, and other activities typically associated with a construction project.
