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. The Charlotte-Mecklenburg Storm Water Services (CMSWS) project team will manage the Chatham Project through the phases listed below.
Planning Phase (Started July 2012)
During the planning phase, the existing conditions are assessed, beginning with aerial and ground survey. Service requests (311 calls), questionnaire responses, field review, and engineering modeling will be overlaid together to analyze problems. After existing conditions are evaluated, a public meeting is held to check our findings against the experience of residents. 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, and this is shared with the residents in another 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. 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 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. The bid phase will begin after all easements are acquired. The easement acquisition phase of a project typically lasts 9 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 (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. The construction phase of this project can last up to 2 years.
