HYDRAULIC ASPECTS OF ENVIRONMENTAL IMPACT OF THE TRIANGLE
EXPRESSWAY PROTECTED CORRIDOR BETWEEN NC 55 BYPASS (HOLLY
SPRINGS) AND US 64 BYPASS (KNIGHTDALE).
TIP PROJECT NO. R-2721, R-2828 AND R-2829
The North Carolina Turnpike Authority (NCTA) proposes to construct a multi-lane
facility on new location between NC 55 in Apex and US 64/264 in Knightdale. The
proposed typical section that is being considered for the project is a 61ane median
divided facility. The leng�h of the proposed corridor is approximately 30 +/- miles. See
the attached quad map for specific locations of the sites. All of the crossings are located
in the Neuse River Basin.
It was discovered during a recent Agency field meeting that during Functional Designs a
project corridor was extended to cover the downstream crossing of Site L This created
Site 1 A, Sunset Lake Road over Middle Creek. This site was never studied in the original
report, therefore, it is now being investigated as an additional site (Site 1 A), as
Addendum #1. The staff of Mulkey, Inc. recently conducted a field investigation and
preliminary hydraulic study for the subject stream crossing. In consideration of all
aspects noted below, the hydraulic recommendations are suinmarized as follows:
Site lA is a crossing of Middle Creek on an existing location; Sunset Lake Road. The
normal water depth at the proposed site is 2.5 feet. The channel has a base width of 25
feet and a depth of 4.5 feet. Average upstream/downstream top of bank to top of bank
measures approximately 35 feet. Recent drift was observed to be 5.0 feet above the
stream bed. Debris potential is high and existing timber debris was noted in the upstream
portion of the channel during recent site visit. The drainage area for this crossing is 3,554
acres (5.55 square miles). A majority of the area is zoned as Residential or Mixed Use.
This crossing is located below headwater. Based on preliminary hydraulic analysis of
this site, it is recommended that the proposed structure be a 100 foot bridge. Further
detailed analysis will be required during final design in order to adequately address all
the impacts associated with the floodplain. The creek is in a FEMA detailed study
Special Flood Hazard Zone AE containing a published floodway. The creek is listed on
the North Carolina Division of Water Quality (NCDWQ) 303(d) list (27-43-15-(1)bl) for
impaired streams. This stretch of creek is located in Class C and NSW per NCDWQ
classifications far this site.
Wake County participates in the National Flood Insurance Regulatory Program. Results
of this study were based upon the current Effective FIRM maps for Wake County. The
Hydraulics Unit will coordinate with the Federal Emergency Management Agency
(FEMA) to determine if a Conditional Letter of Map Revision (CLOMR) and a
subsequent final Letter of Map Revision (LOMR) are required for the project. If
required, the Division will submit sealed as-built construction plans to the Hydraulics
Unit upon project completion certifying the project was built as shown on construction
plans.
2
Wetlands were observed sporadically through the entire corridor. NCDOT `Best
Management Practices for the Protection of Surface Waters" will be utilized throughout
the life of the project. Erosion and sedimentation will be controlled through the
specification, installation, and maintenance of more stringent erosion and sedimentation
control methods. Existing drainage patterns will be maintained to the extent practicable.
Groundwater resources should not be affected by the project, as the roadway approaches
are primarily on fill. Nutrient sensitive buffers are located throughout the entire project.
There are no water supply watershed critical areas located downstream of this project,
therefare Hazardous Spill Basins are not required for this project. It is an�icipated that
construction of the project will require a United States Army Corps of Engineers 404
individual permit and a 401 Water Quality Certification.
