TABLE 7-1 Areas of Potential Impacts to be Addressed by Permitting and Mitigation Programs

Potential for SCI

Types of SCIs

Mitigation

Environmental Resource

LI

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 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 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 Parks and Recreation Master Plan

Topography and Floodplains

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

Soils

PI

Soil erosion and compaction from new development

Land Use

PI

Conversion of agricultural and forested land uses to other developed land uses Redevelopment to higher density land uses
