Mitigation
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
