LI
Loss of floodplain water storage could occur in
areas outside riparian buffers
Isolation of floodplain from stream by channel
entrenchment; loss of nutrient exchange
capabilities; increased sedimentation
Unified Development Ordinance (UDO)
- Open Space Preservation and Land Use Plans often
preserve additional corridors along required riparian
buffers
- Floodplain Protection - no development or fill in
floodway; development in floodplain must obtain
special use permit which limits development in
floodplain; Hazard Mitigation Plan
- Stormwater Programs and Impervious Surface
Limitations
- Sanitary Sewer Installation – avoids laying sewer
lines in riparian buffers
- Floodplain Overlay District - prohibits development
without a floodplain development permit
Erosion and Sediment Control Program administered by
Wake County
Soils
PI
Soil erosion and compaction from new development
Land Use Plans – encourages more intense
development in Town Center, activity centers, and
growth corridors to limit areas of disturbance
