Chattahoochee Corridor Plan Summary

The plan includes development standards that reduce the impacts of development on the river using the existing characteristics of the land and vegetation as a guide to identify development suitability. It is based on ARC’s 1972 Chattahoochee Corridor Study (PDF 23mb) and, for the land added in 1998, the River Corridor Protection Section (PDF) of the 1998 Chattahoochee River from Peachtree Creek to West Point Lake Corridor Plan Study (PDF).

The plan establishes three sets of standards, all of which must be met for consistency with the plan:

Vulnerability Standards:

  • All corridor land is in one of six vulnerability categories based on land characteristics. 
  • Each category has maximum amounts of land disturbance and impervious surface stated as a percentage of category area. 
  • Land disturbance is any activity disturbing the land or existing vegetation. 
  • Impervious surface is any paved, hardened or structural surface regardless of material and includes buildings, driveways, decks, patios, pools, etc.

Buffer Zone Standards:

  • 50-foot undisturbed vegetative buffer along the river and its impoundments. 
  • 35-foot undisturbed vegetative buffer along flowing streams in the corridor. 
  • 150-foot impervious surface setback along the river and its impoundments.

Floodplain Standards:

  • Balancing fill with an equal volume of cut in the river’s 100-year floodplain. 
  • No blocking of flood flows. 
  • 35-foot height limit above existing grade for all structures except bridges in the river’s 500-year floodplain.
