Silver Stream Storm Drainage Improvement Project
The Silver Stream Storm Drainage Improvement Project will reduce street flooding along Swans Run Road and Sheffingdell Drive.  House flooding along Swans Run Road, Silver Stream Road and Bon Rea Drive will be alleviated as well.  Improvements will also be made to channels throughout the neighborhood to address flooding and erosion.  The project is complete.

Objectives:

  - 
Reduce house flooding and street flooding on Swans Run Road and Sheffingdell Drive by replacing the roadway culvert.
  -  Install additional inlets and storm drainage infrastructure in the areas of Bon Rea Drive and Sweetgrass Lane.
  -  Reduce channel erosion by providing spot repairs.
 
Cost:  $2,100,000
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 Storm Water Services (CSWS) project team will manage the Silver Stream Project through the phases listed below.  Specific work is conducted during each phase while an emphasis is made on public involvement throughout the entire project.

Planning Phase (Completed April 2002)
The project team identified areas to be improved in the Silver Stream Project Area.  These improvement areas were identified from citizen calls to 704-336-RAIN and responses to the neighborhood questionnaire. 
 
The City's engineering consultant analyzed the problems and proposed solutions.  CSWS has determined which areas need repairs and has preliminarily sized the new systems.  A public meeting was held in Spring 2002 to inform the property owners of the proposed improvements and receive feedback.
 
Design Phase (Completed May 2004)
The Design Phase began in Summer 2002.  Detailed construction drawings and exhibits were prepared for every property that was affected by improvements. 
 
During this phase, many details were addressed including the determination of specific pipe sizes and alignments, stream widths and lining types, inlet sizes and locations, utility relocations, tree removal and easement locations.  A public meeting was held in late Summer 2003 to update the property owners on the preliminary construction plans.
 
Permitting Phase (Completed February 2004)
During the permitting phase, the required water quality permits and certifications were obtained from Federal and State agencies. 
 
According to Federal and State regulations, all of the small streams/channels in the project area are considered wetlands.  Permit applications were prepared and meetings were conducted with the NC Division of Environment and Natural Resources and the US Army Corps of Engineers.
 
Property Easement/Acquisition (Completed August 2004)
The City's real estate staff worked directly with affected citizens to acquire Storm Drainage Easements (SDEs).  The City requested that affected property owners grant SDEs to provide the City access to their property to perform needed improvements and future maintenance. 
 
The project schedule for this phase depended almost entirely on the responsiveness of property owners.  Timely responses from citizens and donations of SDEs expedite repairs.  The bid phase began after all easements were acquired.

Bid Phase (Completed August 2004)
During the bid phase, the final plans were circulated to qualified contractors for a competitive bidding process.  By state law, the lowest responsible bidder was awarded the construction contract.
 
Construction (Completed August 2005)
Construction began in late Summer 2004 and was completed in August of 2005.
