McDonald Pond Rehabilitation
The objective of the McDonald Pond Rehabilitation Project is to preserve and enhance water quality benefits for downstream waters. These objectives will be achieved by rebuilding the outlet structure and dam of the pond.
McDonald Pond Project Area.
Blythe Development was selected as the lowest responsible bidder by City Council on September 26, 2011, with a low bid of $375,975.

The Charlotte-Mecklenburg Storm Water Services (CMSWS) project team will manage the McDonald Pond Rehabilitation Project through the phases listed below.

Estimated Cost: $830,000
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.
Planning Phase (Completed September 2010)
During the planning phase, several improvement alternatives were developed and evaluated to determine the best solution. A recommended alternative was selected and used as a guide for the design. During this phase, it was discovered that the dam was showing signs of failure with water seeps and rusted-out outlet pipes, requiring the City to perform a temporary repair in July 2010. This repair replaced the outlet pipes in the same location and moved the outfall channel away from the toe of the dam slope. The goal was to reduce the risk of a dam breach occurring prior to the work beginning on the full pond rehabilitation work, and to allow the current water quality benefits of the pond to be maintained. 

Design Phase (Completed July 2011)
The engineering consultant worked closely with Storm Water Services to develop and finalize the design. Personnel from City of Charlotte, the engineering consultant, land surveyors, wetland specialists, and geotechnical engineers worked in the area collecting information necessary to complete the design.

Permitting Phase (Completed July 2011)
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.

Property Easement/Acquisition (Completed March 2010)
The City works with citizens and businesses to acquire Storm Drainage Easements (SDEs) and Temporary Construction Easements (TCEs). The City requests that SDEs and TCEs be donated to provide access to the affected properties to make the recommended improvements and provide future maintenance. The McDonalds provided the essential easements during 2010.

Bid Phase (Completed November 2011)
During the bid phase, the final plans are circulated to qualified contractors for a competitive bidding process. By state law, the lowest responsible bidder is awarded the construction contract. 

Construction Phase (Completed June 2012)

The construction of the pond’s water quality enhancements has been successfully completed on time and under budget. A final walk through of the project took place on June 29. Some highlights of the construction included: 

        • Installation of 2 water quality control risers with intake and outflow pipes to control the release of water during typical rainfall events; 
        • Construction of a concrete emergency spillway to control the release of water during larger rainfall events; 
        • Removal, replacement, and re-grading of the dam embankment; 
        • Application of a decorative stone finish on the new 48” headwall; 
        • Replacement of the 72” headwall at Lake Drive; and 
        • Addition of Grass Carp to assist in controlling the aquatic vegetation around the pond’s perimeter.

Revegetation of the embankment and the disturbed areas within the project limits has also been completed. The establishment of vegetation is susceptible to local weather patterns such as drought, and as such, may take a few growing seasons to fully establish. CMSWS will be monitoring the progress.
