May 2012 Update:
Construction of the McDonald Pond Restoration Project began in March of this year. The contractor, Blythe Development, is making steady progress on the proposed pond improvements, including:
1. Temporarily draining the pond and relocating approximately 1000 fish.
2. Installing new outlet control structures and spillway
3. Installing a new headwall on the existing culvert under Lake Drive
The completion of the dam rehabilitation is on schedule to meet the September 2012 deadline.
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.

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 (Estimated Completion Third Quarter 2012)
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. There are two noticeable phases on projects like this one: major construction and revegetation. The major construction work will be completed in the first six to nine months, weather permitting. Major construction involves earth work, concrete work, and other activities typically associated with a construction project. After the major construction is complete, the revegetation phase will begin.
