The Tyvola Drive Storm Drainage Improvement Project will reduce flooding of streets and structures by improving culverts, pipe systems, and stream channels. Stream banks will be stabilized to minimize erosion through improvements to the channel shape and through the use of selected plantings. The project was completed in March 2007.
- Reduce flooding of South Boulevard and Tyvola Drive and nearby structures by upgrading underground pipe systems and the Tyvola Drive roadway culvert.
- Reduce flooding and minimize erosion along the receiving stream by improving the channel cross-section and alignment.
Please note that this figure includes all costs associated with the project such as planning and design, utility relocation, consultant fees, construction, permitting and landscaping.
The Charlotte Storm Water Services (CSWS) project team will manage the Tyvola Drive Project through the phases listed below. An effort is made to involve the public throughout the course of the project.
Planning Phase (Completed August 2004)
City staff worked with USInfrastructure, Inc. (USI) to plan improvements in the Tyvola Drive project area. Problem areas were identified through a review of citizen calls to 704-336-RAIN and responses to a neighborhood questionnaire. Potential flooding in additional areas was identified through analyses by USI of the neighborhood drainage system. USI developed alternative solutions to address the problem areas and alleviate flooding. A public meeting was held September 30, 2004, at Saint Andrews United Methodist Church to present the findings of the planning study and to solicit comments from neighborhood property owners.
Design Phase (Completed December 2005)
Detailed construction drawings were prepared for the project as well as easement exhibits for each property owner directly affected by the construction. Numerous details were finalized, including pipe sizes and alignments, channel configurations, inlet sizes and locations, utility relocations, landscape changes, and easement requirements.
A public meeting was held May 19, 2005, to present the preliminary design to the neighborhood, and to assist in starting the easement acquisition phase of the project.
Permitting Phase (Completed December 2005)
During the permitting phase, water quality permits and certifications were obtained from Federal and State agencies. Permits were received from the North Carolina Division of Environment and Natural Resources and the US Army Corps of Engineers.
Property Easement Acquisition Phase (Completed July 2006)
The City's real estate staff worked directly with affected citizens and businesses to acquire temporary and permanent easements for the project. Easements allow the City to access properties for construction of the improvements and to conduct future maintenance of the drainage system.
Bid Phase (Completed March 2006)
Construction documents were provided to qualified contractors for the preparation of construction bids. The City follows North Carolina regulations governing the bidding process, and selects the lowest responsible bidder to construct the project. Six bids were received. The construction contract was awarded to Blythe Development Company.
Construction Phase (Completed March 2007)
Construction began March 2006 and was completed in March 2007.
