Areas of Potential Impacts to be Addressed by Permitting and Mitigation Programs
Environmental Resource
Potential
for SCI
Types of SCIs
Mitigation
Surface Water Resources PI
Water quality degradation; increase in
stormwater runoff and sedimentation
Alteration of natural hydrograph
(e.g., magnitude, timing, frequency,
duration, rate of change); lower and more
frequent low-flow conditions; alteration of
channel morphology
UDO
- Stormwater Programs
- Sanitary Sewer Installation – stream crossings with directional
borings
- Water Conservation
- Riparian Buffers and Floodplain Protection – no residential
development or fill in floodplain
Land Use Plans and open space preservation
Parks and Recreation Master Plan
Erosion and Sediment Control Program administered by Wake County
Groundwater Resources
LI
Possible reduction in groundwater inflow
that provides baseflow in streams and
supports aquatic life during droughts
Reduction in use for private drinking water;
potential to become contaminated
Land use planning
UDO
- Open Space Preservation
- Riparian Buffers and Floodplain Protection – allow for natural
infiltration
- Stormwater Programs, including promotion of LID
Water Conservation Programs
Forest Resources
PI
Conversion to other uses
Reduction in air quality; increase in near-
surface air temperature; habitat
fragmentation
Land Use Planning - encourage development in Town Center and
growth corridors, as well as tree and urban forest preservation
Parks and Recreation Master Plan
UDO
- Conservation/Buffer District – promotes preservation of forest
resources
- Open Space Preservation
