The Charlotte-Mecklenburg Storm Water Design Manual provides technical and engineering procedures to assist in the design and evaluation of storm water management facilities in the City of Charlotte and Mecklenburg County. It provides engineering design guidance to:
• local agencies responsible for implementing the Charlotte-Mecklenburg Storm Water Management Program
• engineers responsible for the design of storm water management structures
• developers involved in site planning and design
• others involved in storm water management at various levels who may find the manual useful as a technical reference to define and illustrate engineering design techniques
NOTICE: Charlotte-Mecklenburg Storm Water Services is currently the Charlotte-Mecklenburg Storm Water Design Manual. Proposed changes are needed to remove outdated methodologies, clarify standards and address formatting concerns. A revision log of individual changes to each chapter has been provided on this page. The deadline for receiving input through the public review process was November 6, 2013. We are currently reviewing information received related to the public review. Until the edits are finalized and made effective, the current Storm Water Design Manual is still effective.
