Storm Water Design Manual

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 recently revised the Charlotte-Mecklenburg Storm Water Design Manual.  Proposed changes were needed to remove outdated methodologies, clarify standards and address formatting concerns. This is now an electronic, fully searchable document.  A revision log of the individual changes to each chapter has been provided on this page. This new edition of the Storm Water Design Manual is currently effective as of January 1, 2014.
