for SCI
Types of SCIs
Mitigation
Topography and
Floodplains
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
Parks and Recreation Master Plan
Erosion and Sediment Control Program administered by Wake County
UDO
- Riparian Buffers and Floodplain Protection
- Stormwater Programs and Impervious Surface Limitations
- Open Space Preservation
Land Use
PI
Conversion of agricultural and forested
land uses to other developed land uses
Redevelopment to higher density land
uses
UDO
- Open Space Preservation
- Riparian Buffers and Floodplain Protection – restricts development
in riparian buffer zones and prohibits nearly all floodplain
encroachment
- Stormwater Programs
Land Use Plans to encourage development around Town Center and
Activity Center Districts
