Agenda for Meeting: • Project Description and Status • Discussion of Bridging Locations and Alignment Review • LEDPA Decision • Discussion of Avoidance and Minimization efforts • Comments and Questions Project Planning Engineer: Brad Smythe, P.E. (919)733-7844 extension 252 bsmythe@dot.state.nc.us R-2583 Merger Team Meeting Concurrence Points 2A, 3, 4A January 17, 2008 Project Description TIP Project R-2583 involves the widening of US 158 in Hertford County to a multi- lane facility from the Murfreesboro Bypass to US 13 West of Winton (Figure 1). The total length of the project is currently listed at 8.3 miles. According to the Draft 2008-2015 TIP, right-of--way acquisition for the project is scheduled to begin in state fiscal year 2010, with construction to begin in state fiscal year 2012. The current estimated total cost, as listed in the Draft TIP, is approximately $44,978,000. The US 158 intrastate corridor extends from Winston-Salem to Whalebone and is listed as one of North Carolina's Strategic Highway Corridors. Within the project limits, US 158 is a two-lane highway. There is currently no access control along the project section, as evidenced by numerous driveways and small streets that intersect the project. All intersections are at-grade crossings. Mapleton is the only populated community within the project limits. The existing highway extends between scattered residences, agricultural fields, and wooded areas. US 158 crosses Potecasi Creek within the project limits; the current crossing consists of a two-lane bridge approximately 119 feet in length. Project Schedule/Cost Right-of way acquisition for the project is scheduled to being in federal fiscal year 2010 and construction is scheduled to begin in federal fiscal year 2012. The most recent cost estimates for the project are as follows: Right of Way/IJtilities Construction Total: Current Estimate Range: $ 8,150,000 - $ 8,830,000 $35,100,000 - $38,100,000 $43,580,000 - $46,450,000 Purpose and Need The merger team agreed to the project's purpose and need at the merger team meeting on January 15, 2003. The purpose of the project is to: Provide system linkage; Support economic development; and Ensure future safety along the project limits on US 158 in Hertford County. R-2583 Merger Team Meeting Concurrence Points 2A, 3, 4A January 17, 2008 Detailed Study Alternatives Carried Forward Concurrence Point 2 was approved by the Merger Team on May 19, 2005. The team agreed to carry the following alternatives forward for detailed study: Alternatives A, B, and C. Alternative A: Widen on Existing This alternative would widen the roadway entirely on its existing location. The alternative includes the construction of a new, two-lane bridge over Potecasi Creek north of the existing structure. The existing Potecasi Creek Bridge would be replaced. Alternative B: Widen on Existing with Northern Bypass This alternative is the same as Alternative A with the exception of a new location section north of the Mt. Tabor Church Road (SR 1176) intersection. The new location section would serve to straighten the existing curve as well as to avoid impacts to the nearby Mt. Tabor Baptist Church property. This alternative would also include a new crossing of Potecasi Creek in the form of a two-lane bridge to be located north of the existing crossing. The existing Potecasi Creek Bridge would be replaced in the same location with a longer bridge. Alternative C: Widen on Existing with Southern Bypass This alternative is the same as Alternative A with the exception of a new location section east of Mt. Tabor Church Road (SR 1176). The new location section would both straighten the existing curve as well as avoid impacts to the historic church property. This alternative would include the construction of new dual two-lane bridges over Potecasi Creek, both to be located south of the existing crossing. If this alternative is selected, the existing Potecasi Creek Bridge along with some causeway would be removed for mitigation. Mapleton Service Road Option The Mapleton Service Road option was developed after the last merger meeting to address relocation impact to this minority community. This alternative would build afour- lane typical section on new location, south of the existing two lanes in the Mapleton community. This alternative decreases impacts to this minority community and would leave the existing two lanes in place as a service road to the homes on the north side of the roadway. This option forms alternatives A2, B2, and C2. R-2583 Merger Team Meeting Concurrence Points 2A, 3, 4A January 17, 2008 Concurrence Point 2A Bridging Decisions and Alignment Review Table 1 shows the summary of impacts for each alternative. Tables 2 & 3 show the wetland and stream impacts recalculated based on current designs. Along the eight-mile corridor, there are two major drainage features that most likely require concurrence from the Merger Team. The first location is the crossing of Potecasi Creek. This creek flows from south to north across each of the alternatives and drains approximately 238 square miles, eventually flowing into the Chowan River. The existing US 158 roadway crosses this creek with a bridge approximately 120 feet long. Alternatives A and B utilize the existing alignment through this location and propose to replace the existing bridge with dual bridges, approximately 200 feet long. Alternative C proposes a new location segment that requires the construction of dual bridges, approximately 200 feet long, south of the existing bridge location. In Alternative C, the existing bridge will be removed for mitigation, along with as much of the causeway as possible. The second location involves Mill Branch, which passes under the existing roadway via a culvert with three additional culverts within the wetland system adjacent to the creek. NCDOT was asked at the Concurrence Point 2 meeting to investigate building a bridge at this location in place of the existing culvert. NCDOT evaluated this option. Due to the current vertical alignment at this location, the construction of a bridge results in the raising of the roadway grade by approximately 8.5 feet. In turn, this increases the roadway footprint on the approach to the bridge. In addition, replacing the culvert with a bridge, will require the construction of an onsite detour, further increasing wetland impacts, albeit temporarily for construction. Hydraulic recommendations are shown in Table 4 of this document. This provides a summary for decision making. R-2583 Merger Team Meeting Concurrence Points 2A, 3, 4A January 17, 2008 Concurrence Point 3 Selection of the Least Environmentally Damaging Practicable Alternative (LEDPA/Preferred Alternative) Public Hearing Update: Of the comments received after the public hearing, over forty responses were in favor of Alternative C, which builds four lanes on new location to the south of the Church. The residents were concerned with impacts to the church, cemetery, and residences in the area. Although not represented in the written comments received, the Mapleton Service Road Option, which saves 15 homes, was also preferred over the widen existing alternative through Mapleton. This is based on discussions with members of the public who attended the Public Hearing in July. Discussion of Sections/Alternatives: Mapleton Service Road Option vs. Widen on existing: • Service Road saves 15 relocations. • Service Road impacts more wetlands/streams/farmland. (See Tables 2 & 3) Alternative A (Widen Existing): • Fewer natural environment impacts. • Undesirable curves in Mt. Tabor Church area. • Impacts Mt. Tabor Church and Cemetery. Alternative B (Northern): • Eliminates curve at Mt. Tabor Church. • Avoids impacts to Church and Cemetery. • More wetland/stream impacts than A and C. Alternative C (Southern): • Eliminates curve at Mt. Tabor Church. • Avoids impacts to Church and Cemetery. • More wetland/stream impacts than A but less than B. Higher quality impacts than B. • Requires new location, for bridging Potecasi Creek, but would remove existing bridge. NCDOT Preferred: After considering all factors, NCDOT proposes Alternative C with the Mapleton Service Road option as its preferred alternative. R-2583 Merger Team Meeting Concurrence Points 2A, 3, 4A January 17, 2008 Concurrence Point 4A Avoidance and Minimization • Existing Potecasi Creek Bridge will be replaced with a longer bridge for both the A or B alternatives. • Part of the US 158 causeway will be removed for the C alternative. • Alternatives B and C were added to the project to avoid impacts to the Historic Mount Tabor Baptist Church and its cemetery. • The Mapleton Service Road alternative was included as an alternative to minimize impacts to the minority community as well as to the Historic Britt Store. • The alignment has been shifted to the south near Mill Branch, which reduced impacts to wetlands WD, WC, and WB. This shift also results in avoiding impacts to the electrical sub-station located just west of Parkers Ferry Road. • At the east end of the project, widening was done to the north to minimize impacts to wetland WA.

There are no records of the Red-cockaded woodpecker within one mile of the study area. While limited suitable habitat does exist within the study area, no individuals or nest cavities of this species were observed during a site visit. zThe Chowanoke Crayfish (Orconectes virginiensis) is listed as FSC by the USFWS and SC with the State. Though there is potential habitat for this species within the study area, the NCNHP database shows no occurrence of FSC within one mile of the study area.
