Established in 1999, the City's Stormwater Utility is responsible for the maintenance and upgrades to the stormwater system including pipes, culverts, inlets, manholes, headwalls, flumes, concrete channels and related appurtenances. It is also responsible for the enforcement of environmental regulations, and for the City's compliance with Clean Water Act requirements and other environmental regulations related to stormwater.

A Stormwater Master Plan study, now in its final phase, will inventory the extent of and analyze the performance of the overall stormwater system. It will also assess the condition of the existing system and make recommendations for necessary maintenance and upgrades to the aging infrastructure. The master plan will also address required and recommended capital improvements to upgrade the capacity of the system where necessary.

The Utility's long-term goal is to implement the Stormwater Master Plan recommendations, provide on-going maintenance and provide for system upgrades subject to funding availability.

The Stormwater Utility has stepped up maintenance efforts and undertaken several construction projects to maintain and improve the existing system over the last three years. Small repairs and upgrades that do not require heavy or specialized equipment are performed by in-house crews; however, larger projects are bid on and contracted out. A sampling of improvement projects completed in the last three years are:

  • Replacement of a failed culvert at Glenlake Park
  • Replacement of a failed culvert on Willow Lane
  • Addition of a storm sewer line at the Kings Highway and West Davis Street intersection
  • Addition of a storm sewer system on East Trinity Place and sections of Church Street
  • Addition of a storm sewer line on West Ponce de Leon Avenue in the vicinity of Fairview Avenue

The last two projects listed were performed in conjunction with the City's streetscapes project to minimize the overall disruption to those areas. Several smaller stormwater system repair projects have been performed by in-house crews throughout the City. Future repair and improvement projects will be prioritized based on Stormwater Master Plan recommendations, unanticipated system failures, and other regulatory requirements.

Environmental Regulations

Stormwater markerThe Stormwater Utility participates in the Metropolitan North Georgia Stormwater Watershed Association's efforts to develop revised environmental regulations for the 16-county region. The new environmental regulations are intended to reduce pollutants entering the streams and will be applicable to new development and redevelopment during and after construction. Enforcement of the new regulations, when finally adopted, will be performed by the Stormwater Utility.

This marker shown is being affixed to every stormwater inlet location where illegal dumping can occur. Over 500 markers have been installed so far throughout the City.
