Design Phase for the Hampton Avenue Storm Drainage Project started during the first quarter of 2013. The consultant has analyzed the existing storm drainage system and compared the modeled results to the input received from property owners at the public meetings.
Storm Water Services has a standard questionnaire for property owners to provide their input and concerns. The input that we have received to date documents existing storm water related problems in the area. These problems include road flooding, house flooding, and channel erosion. The proposed design alternative will include pipe and culvert replacements as well as channel cleaning and stabilization.
If you are experiencing drainage issues on your property please take the time to complete a questionnaire.
Please check back for informational updates.
-Reduce structure and street flooding.
-Address channel capacity and erosion problems.
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 the Hampton Avenue Project through the phases listed below which include typical time frames and descriptions of the project phases. Even though specific work is conducted during each phase and emphasis is made on public involvement throughout the entire project.
Planning Phase (Completed January 2013)
The Planning Phase consisted of field surveying, evaluating the existing drainage systems to determine areas of flooding and erosion damage, evaluating alternatives to reduce flooding and erosion, and preparing a final recommendation. During the planning phase, questionnaires and public meetings were used to obtain input from property owners. After preliminary reviews from the project report and recommendation, CMSWS decided to explore additional alternatives for the project.
CMSWS has investigated and analyzed alternatives based upon:
• Benefit/Cost Analysis
• Floodproofing existing structures
• Rehabilitation of the existing drainage system
Design Phase (Began February 2013)
During the design phase, construction drawings for the alternative selected during the planning phase are developed. Many details must be addressed including the determination of specific pipe sizes and alignments, channel widths and lining types, inlet sizes and locations, utility relocations, and easement locations. The design phase of a project typically lasts 21 to 34 months.
A public meeting was held on October 11, 2012 to present the preliminary design to the neighborhood and to assist in starting the property easement/acquisition phase of the project.
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 Storm Drainage Easements (SDEs). The City requests that SDEs be donated to provide access to your property to make the recommended improvements and provide future maintenance. In addition to SDEs, temporary construction easements may be needed to access work areas. The bid phase will begin after all easements are acquired. The easement acquisition phase of a project typically lasts 10 to 14 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 7 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 and will be mailed to residents prior to construction. Because projects vary in size, the typical construction phase of a project can last from 3 months to over 2 years.
