The project location is shown in Exhibit 1. This project involves adding lanes, reconfiguring the I-77 interchange, rehabilitating/replacing several bridges, and access management. Improvements to the I-77 interchange are identified in the STIP as Project No. I-5717; however, to ensure a coordinated design, NCDOT is combining the two STIP projects into one environmental document. The NCDOT proposes this approach because the projects are adjacent to each other and, it would be practical to develop the interchange modifications in coordination with the NC 150 improvements proposed under the R-2307 project. A planning, environmental, and engineering study is being conducted for the proposed action in accordance with the National Environmental Policy Act of 1969 (NEPA), as amended, and the FHWA's Guidance for Preparing and Processing Environmental and Section 4(f) Documents (FHWA Technical Advisory T6640.8A, October 30, 1987). An Environmental Assessment (EA) will be prepared to document project studies and to present the potential environmental impacts associated with the proposed action. The purpose of today's meeting is to reach agreement on Concurrence Point 2A (Bridging Decisions and Alignment Review). This document presents the existing structures, recommended structures, and environmental considerations for each major drainage structure location. The draft CP2A form can be found in Section 4.0. 1.1 Project Background NC 150 is classified as an arterial and is predominately a 2-lane undivided facility that widens to a 5-lane facility with a center shared turn-lane through the Town of Mooresville to the eastern terminus of the project at the US 21/ NC 150 interchange. NC 150 is a major east-west route between Shelby, Lincolnton, and Mooresville. According to the 2013 American Community Survey 5 Year Estimates, 45,383 people live in the project study area. The western portion of the project study area is predominantly rural in nature with single family neighborhoods clustered around Lake Norman. In the eastern portion of the study area, through the Town of Mooresville, extensive commercial development and high density neighborhoods are the predominant features. The project study area contains numerous recreational opportunities and attractions, most notably the Terrell Historic District, Marshall Fishing Area, Pinnacle Access Area, and McCrary Creek Access Area. All of the named lake access areas are owned by the Duke Energy and managed by the Wildlife Resources Commission. Numerous other land uses, including subdivisions, commercial properties, and churches are also located in the study area (NCDOT Project Development and Environmental Analysis eranch 2012). The environmental features of the project study area are shown in Exhibits 2A — 2D. 1.2 Uniqu� Pr�ject Ch�r�cteristics Multiuse Path — An approximately seven-mile long multiuse path is being evaluated from Little Mountain Road to Perth/Dooley Road. The path would be constructed on the northern side of NC 150 outside of the proposed roadside ditch. The multi use path will be located to the north since Bridge No. 138 (long bridge over the Catawba River near the Marshall Steam Station) is currently undergoing a 4 million dollar rehab and the rehabilitated structure will not accommodate a multi use path. The path would also cross four other bridge structures. NCDOT is providing six-foot paved shoulders in their design which will accommodate bikes and allow for pedestrian use. The 6-foot shoulders are being provided since NC 150 is a signed bicycle route, is part of the Carolina Thread Trail, and is also noted in local MPO regional bicycle plans. If the path is included in the project, there would be additional hydraulic impacts from the extension of currently proposed culvert lengths or other means to cross smaller streams. The multi-use path will be R-2307 & I-5717 CP2A MEET�NG — JuNE 10, 2015 included in the environmental document as a modular section that can be added or removed based on funding availability. Ma.rshal! St��arrr Statior� — The Marshall Steam Station is located on the north side of NC 150, just west of Mooresville near the long bridge (Bridge #138) crossing of Lake Norman. The plant's facilities are immediately adjacent to existing NC 150 and include two driveway access points. The Marshall Steam Station has been determined to be National Register (NR) eligible. The historic boundary for the steam station is shown in the adjacent image on the right. FERC Permit Coordination — The NC 150 project will impact property regulated by the Federal Energy Regulatory Commission (FERC). Duke Energy is the FERC license holder for this resource. NCDOT has begun coordination with Duke Energy to determine which impacts and areas may be considered allowable under the conditions of their FERC license, or if modification of their FERC license is necessary. Impacts may be especially complex near bridges, causeways, public access ramps, and other lake-related areas where avoidance and minimization efforts are complicated by impracticable engineering efforts or FERC license requirements. Coordination is ongoing; updates will be provided to the NEPA/404 Merger Team at subsequent meetings. Terrell Historic Distr�ct — NC 150 traverses the Terrell Historic District in the area surrounding the intersection of Sherrills Ford Road and NC 150. Historic properties include the Sherrill-Gabriel House and the r. � � Terrell Country �� Store, which are ��, ,,�� , . ,,%�s;� + '"�..�'� both located at the � �-�� ` � ' � �" ''�j '"� � �� 4�411� � intersection NC �`' , ` +�M . ,' ! �+:-� 150 and Sherrills Ford Road.

The need for project is based on: Traffic volumes • The existing capacity is 12,700 vehicles per day (in the two-lane segment). Today over 20,000 cars traverse the two-lane stretch of NC 150 daily. Existin� & prolected LOS • The current year volume-to-capacity ratio is 1.57 (in the two-lane segment), well over a LOS F. In 2035, the volume to capacity ratio is expected to exceed 2.19, and could be as high as 3.29. Safety • This stretch of NC 150 exceeds the statewide and critical rates. Rear-end crashes were the largest percentage of crashes. � ,, ... �- ; �• � .: �- . ., ,, The NEPA/404 Merger Team met on August 13, 2014 to discuss the proposed NC 150 Improvements in Catawba and Iredell Counties. The purpose of the meeting was to: 1) obtain Concurrence Point 1(revised) to reflect a single environmental document for the R-2307 and I-5717 projects; and 2) reach Concurrence Point 2 to determine which alternatives to carry forward for detailed study. The Merger Team reviewed the project limits and decided to extend the eastern terminus of the project to just west of the US 21/NC 150 interchange in Mooresville to allow for access management solutions on both sides of the NC 150/I-77 interchange. The merger team also considered the no-build alternative, TDM and TSM improvements, mass transit alternative, and a range of build alternatives that would widen existing NC 150. � ,+'� � ,��. ...; �� ' �, f� ��i`. � �� ,►'- � ---��'�� .�: �'ri.\/' +;'�i The build alternatives included several options to bypass the Terrell Historic District, including two avoidance alternatives and one minimization alternative. The minimization alternative, Alternative 3(shown as the turquoise R-2307 & I-5717 CP2A MEET�NG — JuNE 10, 2015 corridor line in the above figure), crosses the southernmost portion of the historic district. SHPO noted that although this alternative would not impact any structures, it would potentially change the district's character, resulting in an adverse effect and Section 4(f) impacts. The Merger Team agreed to eliminate Alternative 3 from further study. The alternatives retained for detailed study include: Alternative 1: Best Fit -Widen Existing NC 150 (No Terrell Bypass Option) (in orange aboveJ Alternative 2: Best Fit — Widen Existing NC 150 & Northern Terrell Bypass Option (in pink aboveJ Alternative 4: Best Fit — Widen Existing NC 150 & Southern Terrell Bypass Option (in purple aboveJ There was brief discussion of other topics including median width, control of access, and Section 4(f). It was noted that the 46-foot median proposed for the bypass options is a result of the rural nature of the project area, the proposed design speed and safety considerations (eliminate median crossings and the potential for head-on collisions). It was also noted that a 23-foot median is proposed through the Terrell Historic District and that future efforts will include studying the use of a 17-foot median through Terrell. It was requested that the 23-foot median begin where the bypass options diverge from existing NC 150 rather than at the historic district boundary. Typical Sections are provided for reference in Appendix A. 3,0 Coneurrence Point 2A: Bridging Decisions and Alignment Review The following sections include information on the existing major drainage structures along NC 150 and recommendations for proposed structures. Exhibit 3 shows the site location for each major drainage structure associated with Alternatives 1, 2, and 4. Existing major drainage structures are located at Sites 1-5 and 11-16. Sites 6-10 are major drainage structures on new location associated with the Terrell bypass options. 3.1 Existing I�I�j�r Drainage Struetur�s Site No. 1: The existing structure is a single-barrel S ft. by 5 ft. reinforced concrete box culvert (RCBC). The west fork of Killian Creek flows from northwest to southeast through the culvert under NC 150. Also, there is a 48" reinforced concrete pipe (RCP) with a brick headwall that acts a"high water" release structure. Site No. 2: The existing structure is a single-barrel 4 ft. by 4 ft. reinforced concrete box culvert (RCBC). The east fork of Killian Creek flows from northwest to southeast through the culvert under the NC 150. The inlet of the culvert contains 0.2 ft. of sediment and increases slightly towards the outlet. The culvert inlet and outlet both appear in good condition. Both ends show moderate, abrasive surface wear of the concrete due to age and fluctuating water flow. Site No. 3: The existing structure at this site is bridge #170012 and is a reinforced concrete deck on precast pre-stressed concrete girders. Reed Creek flows from north to south under NC 150 at this bridge. The structure was built in 1961 and has an estimated remaining life of 29 years. The bridge is not classified as deficient and carries a sufficiency rating of 68.01. Site No. 4: The existing structure at this site is bridge #170044 and is a reinforced concrete deck on PPC girders. Mountain Creek flows from north to south under NC 150 at this bridge. The structure was built in 1961 and has an estimated remaining life of 34 years. The bridge is not classified as deficient and carries a sufficiency rating of 69.03. Site No. 5: The existing structure is a single-barrel 5 ft. by 5 ft. reinforced concrete box culvert (RCBC). Bettie Creek (Branch) flows from north to south through the culvert under NC 150. The culvert is in good condition with moderate R-2307 & I-5717 CP2A MEET�NG — JuNE 10, 2015 surface wear of the barrel and wing walls relative to the age of the structure. There is about 0.2 ft. of sediment at both the inlet and outlet. Site No. 6: The existing structure is a single-barrel 8 ft. by 9 ft. reinforced concrete box culvert (RCBC). Beaverdam Creek flows from northwest to southeast through the culvert under NC 150. The culvert has been extended on both ends. The existing top edge is arched but the top inside barrel elevation of both extensions is set at the top of the arch. The outlet is perched approximately 1 ft. and rock appears to have been placed in the streambed below the outlet elevation. There is no sediment buildup on either end and the low flow is an indication of the footer being considerably higher than the streambed. Also, the road cover appears to be less than 2 ft. of fill. Overall the culvert is in fair condition. Site No. 7: The existing structure at this site is bridge #170117 and is a reinforced concrete deck on steel girders. The bridge spans NC 150 over a discharge channel. The structure was built in 1963 and has an estimated remaining life of 34 years. The bridge is not classified as deficient and carries a sufficiency rating of 52.51. Site No. 8: The existing structure at this site is bridge #170138 and is a reinforced concrete deck on I-beams and steel plate girders. The structure was built in 1961 and has an estimated remaining life of 19 years. NC 150 crosses over the Catawba River (Lake Norman) at this site. The bridge has a sufficiency rating of 40 and is structurally deficient. This bridge recently had a 4 million dollar rehabilitation which will further extend the life of this bridge. Site No. 9: The existing structure is a 60 in. reinforced concrete pipe (RCP) with a headwall. An Unnamed Tributary of Reeds Creek flows from north to south through the culvert under NC 150. The pipe and headwall appear in good condition. The outlet end of the pipe has large rocks that have been placed on the banks for protection. Site No. 10: The existing structure is a single -barrel 6 ft. by 6 ft. reinforced concrete box culvert (RCBC). An Unnamed Tributary of Reeds Creek flows from north to south through the culvert under NC 150. The inlet of this structure consists of a 78 in. corrugated metal pipe that is located in a wooded area behind Randy Marion Chevrolet. The pipe is buried along the east side of the parking lot and junctions with the culvert on the north side of NC 150. The pipe appears to be in fair condition. The outlet end of the culvert appears in good condition with minor and moderate surface wear of the barrel and wing walls. The footing is 10 in. higher than the water surface elevation with shallow scouring of the stream bed. Site No. 11: The existing structure is a 60 in. corrugated metal pipe (CMP) projecting. An Unnamed Tributary of Reeds Creek flows from north to south through the culvert under NC 150. The inlet of the pipe was obstructed due to recent clearing of the fill slope area. The outlet end of the pipe appears in fair condition. 3.2 IV1�jor Dr�ina�e Structure Recornmendations Major drainage structure recommendations are provided in Table 1. 4�.0 Merger Project Te�m Agreement Si�nature Form The CP 2A form is shown on the following page.
