The objective of the Raintree Pond at Hole Number Four Project was to preserve and enhance the water quality of receiving waters. These objectives were achieved by modifying the outlet structure and repairing the dam of the pond.
|The pond is located south of Woodfox Drive, north of Fairway Downs Court, east of Strawberry Lane and west of Rounding Run Road on hole number four of the north course of the Raintree Golf course. The dam was determined to be unstable with a reasonable at risk that the dam could fail.
Estimated Cost: $680,000
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.
The Charlotte-Mecklenburg Storm Water Services (CMSWS) project team managed the Raintree Pond at Hole Number Four Project through the phases listed below.
Planning Phase (Completed Summer of 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.
Design Phase (Completed Spring of 2011)
The engineering consultant worked closely with Storm Water Services to develop the design. Designs are not considered complete until all permits are obtained, as the regulatory agencies may provide input which can influence the final 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 November 2011)
During the permitting phase, the required water quality permits were obtained from Federal and State governments. The design also required North Carolina Dam Safety approval. Please note: the permitting phase of a project may overlap other phases.
Property Easement/Acquisition (Completed Spring of 2011)
The City of Charlotte worked with citizens and organizations to acquire Storm Drainage Easements (SDEs), Access Easements (AEs) and Temporary Construction Easements (TCEs). The City of Charlotte requested that SDEs, AEs, and TCEs be donated to provide the City of Charlotte access and certain rights to the affected properties to make the recommended improvements and provide future maintenance. The essential easements have been donated to complete the construction efforts.
Bid Phase (May of 2011 to November of 2011)
During the bid phase, the final plans were 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 (November of 2011 to February of 2012)
Throughout construction, efforts were made to minimize disruption to nearby property owners. Construction of proposed improvements were supervised by a City of Charlotte Inspector. Notifications of key construction dates were mailed to residents prior to construction. Negotiations have been made with project stakeholders, which intended to limit major construction activities to the months of November through March. Construction involves earth work, concrete work, and other activities typically associated with a construction project.
