Coliseum Creek Stream Restoration Project

The Coliseum Creek Stream Restoration is intended to improve water quality to the City's stream system.  There is potential for restoration, enhancement and preservation work to the open channels starting at the upstream channel (just south of Billy Graham Pkwy) and extending downstream (under Tyvola Rd.) to its outlet at Sugar Creek.  These channels are approximately 5,300 linear feet and are located along private and public property. This project will create, enhance, and protect forested riparian areas and aquatic habitat.

HDR Engineering, Inc. is the consulting engineering firm for this project and this project is currently in the Planning Phase. Stream restoration projects have several phases - please see below for more detailed descriptions and timeframes for the upcoming phases and also phase which have been completed.

Currently the project is on schedule but more detailed information will be provided as the project progresses.

Coliseum Creek CIP Area Map

Objectives:

  • Changing the stream path to a more natural design
  • Stabilizing eroded creek banks
  • Restoring the floodplain to its natural state and function
  • Enhancing water quality
  • Construct Best Management Practices (BMPs) to reduce the pollution in Coliseum Creek and its tributaries.
  • Improve habitat for aquatic life and improve stream conditions utilizing stabilization and restoration techniques.

Cost:  To Be Determined
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 Coliseum Creek Stream Restoration Project through the phases listed below.  A general description and range of typical timeframes for project phases has been given.  Specific work is conducted during each phase while an emphasis is made on public involvement throughout the entire project.

Planning Phase (Completed December 2012)
During the planning phase, questionnaires and public meetings are used to obtain input from property owners.  The existing open channel and enclosed drainage system is evaluated to determine areas of flooding and erosion damage. Several improvement alternatives are developed and evaluated to determine the best solution.  Restoration and stabilization opportunities versus implementation costs were explored.  Ultimately, the most cost effective alternative to provide reduction of erosion, stabilize stream segments and restore the floodplain for water quality benefit was chosen. A recommended alternative is presented to the public for comment at the end of the planning phase.  The planning phase of a project typically lasts 12 to 27 months.

Design Phase (Start January 2013 – TBD)
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 restoration levels, inlet sizes and locations, utility relocations, and easement locations.  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 railroad and NCDOT rights-of-way will be obtained during this phase.  The permitting phase of a project typically lasts 3 to 9 months.  The permitting phase of a project may overlap other phases.

Property Easement/Acquisition (Start Date March 2012)
The City's real estate staff works with citizens and businesses to acquire Storm Drainage Easements (SDEs) and Conservation Easements (CEs).  The City requests that SDEs and CEs 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 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 4 to 5 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.
