Stream Buffers (SWIM) and Fences

Why buffers exist

Natural stream banks with trees and shrubs filter runoff, cool water, reduce erosion and give wildlife a corridor. Charlotte’s streams flow to the Catawba River and its lakes.

Fencing on a creek lot

• Keep the fence out of the buffer unless allowed
• Avoid clearing vegetation for a fence line
• Choose open fences that don’t trap debris
• Never block drainage paths
• Expect floodplain mapping near larger streams

Other water rules

• Floodplain: see Floodplains and fences
• Post-construction stormwater rules (UDO Article 25) on newer developments
• Water supply watersheds (UDO Article 23) near drinking water lakes like Mountain Island

Buffer zones

Stream buffers typically include zones closest to the stream with the most protection and outer zones with more allowed uses. Exact widths depend on the stream and rules.

Approvals

Disturbance in a buffer may need approval from the city or county. Ask before building.

Good practices

Keep vegetation intact, use open fences and avoid storing materials near streams.
