Hydraulic Aspects of Environmental Impact 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. 3 � N � N z � � N � N a � N � N z II.
