Appendix C-2 PRELIMINARY FINAL SECTION 106 HISTORIC RESOURCES EFFECTS DOCUMENT Department of Transportation Federal Aviation Administration Preliminary Final Historic Resources Survey & Effects Assessment for New Runways, Terminal Facilities and Related Facilities at Washington Dulles International Airport Washington Dulles International Airport Dulles, Virginia August 2005 For further information: Mr. Joseph Delia Department of Transportation Federal Aviation Administration Washington Airports District Office 23723 Air Freight Lane, Suite 210 Dulles, VA 20166 703.661.1358 ABSTRACT URS Group, Inc. (URS) of Gaithersburg, Maryland conducted a historic resource survey of above-ground resources within the Area of Potential Effects (APE) of the proposed runway expansion project at Dulles International Airport (Dulles) between February and March 2003 and between April and June 2004. These resources are located within the APE of the proposed runway and airport expansion alternatives at Dulles as detailed in URS correspondence sent to the Virginia Department of Historic Resources (VDHR), dated February 26, 2003. The APE includes both the area directly impacted by construction activities and the area indirectly impacted by an increase to the existing decibel levels. Dulles is located on the border of eastern Loudoun and western Fairfax Counties, Virginia and is bordered by State Route 267 to the northeast, State Route 28 to the east, U.S. Route 50 and a series of industrial and business parks to the south, and State Route 606 to the west. Two additional runways and associated improvements are needed to enable Dulles to provide adequate airside capacity to accommodate future aviation activity levels with acceptable operational delay. The proposed development would involve construction of one runway parallel to existing Runway 1L/19R and one runway parallel to Runway 12R/30L. The project would also include the construction of taxiways, a new Tier 3 Concourse, and other associated support facilities such as lighting systems and navigational aids. Three alternatives, No Action, Build Alternative 3, and Build Alternative 4 are being considered. Because the Federal Aviation Administration (FAA) proposes to fund this project, the airport expansion is subject to review pursuant to Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended, and its implementing regulations, 36 CFR Part 800, “Protection of Historic Properties.” This survey report is also in support of an Environmental Impact Statement (EIS) as mandated under the National Environmental Policy Act (NEPA), which will provide the FAA with a comprehensive review of the environmental impacts associated with multiple design alternatives. Ten architectural resources (buildings, structures, objects, and/or complexes) were identified within the APE for the proposed Dulles runway alternatives and surveyed at the reconnaissance- level. One resource, Dulles Airport Historic District (053-0008) has previously been determined eligible for listing in the National Register; and one resource, Sully Plantation (029-0037), is listed in the National Register. The FAA and MWAA have determined that the remaining eight historic resources are not eligible for listing in the NRHP and have received concurrence on seven of these resources from the SHPO in their July 1, 2005 letter to the FAA. The McCulloch Farm Ruins (VDHT # 053-5264 and 44LD543) was determined to be ineligible for listing in the National Register under Criteria A, B, or C by the SHPO in October 2004. Phase II evaluation of the site, which was completed in July 2005, determined that the site is not eligible for the National Register under Criterion D. Concurrence with FAA and MWAA’s determination is pending. Table 1 provides a summary of each property’s National Register status and the adverse effects, if applicable, to that resource from each of the three alternatives under consideration. i ABSTRACT The APE has been altered from the September 2004 Draft Section 106 Report, leading to the removal of four historic properties from consultation, as NOAA/NWS is conducting their own environmental review for the relocation of their facilities, including NEPA and Section 106 consultation. The four properties which were removed from the report are: • 053-5253 • 053-5254 • 053-5255 • 053-5256 A total of 53 archaeological sites were identified within the APE for the proposed Dulles runway alternatives. Phase I survey for the entire Dulles facility was completed in 2004. SHPO concurrence with the Phase I findings was received in November 2004. Phase II evaluations were recommended for 14 sites to determine if they are eligible for inclusion in the National Register and were completed in July 2005. One archaeological site (44FX2840) has been determined to be eligible for listing in the National Register and concurrence received from the SHPO. An additional three sites (44LD538; 44LD539; and 44LD1042) have been determined to be eligible for listing in the National Register by the FAA and MWAA and consultation for these sites is ongoing. A Memorandum of Agreement (MOA) is currently being developed between these parties to address the completion of the archaeological investigations. A copy of the draft MOA is included in Appendix A of this report. The No Action alternative would have no effect on historic resources. No historic properties would be affected by this action as there would be no construction, demolition, or changes to the existing decibel levels. Both Build Alternative 3 and Build Alternative 4 would have an impact on historic resources. Sully Plantation (VDHR #029-0037) would not experience an adverse effect due to either of these build alternatives. Noise modeling indicates that the aircraft-related noise level at this historic resource would either remain the same, or experience an estimated 1 dBA decrease. Preliminary analysis suggests that there would be no adverse effect to the Dulles Airport Historic District (VDHR #053-0008) due to Build Alternative 3 and Build Alternative 4. The construction of two new runways would have no adverse effect on the Dulles Airport Historic District (VDHR #053-0008). However, FAA considers the proposed Tier 3 Concourse Improvements and associated utility improvements, as well as other associated actions within or proximate to the District, to be a connected action in support of the build alternatives. Formal Section 106 consultation for the Dulles Airport Historic District (VDHR #053-0008) regarding the level of effect, if any, will be postponed by FAA until more detailed information regarding the proposed Tier 3 Concourse Improvements, and associated construction, is developed. This approach is consistent with a phased identification and evaluation of historic resources, as described in 36 CFR 800(4)(b)(2). FAA and MWAA have determined that four archaeological sites eligible for listing in the National Register will be adversely affected by Build Alternative 3 and Build Alternative 4. For each of these sites, Phase III Data Recovery or In-Situ Preservation will be undertaken in accordance with stipulations outlined in the MOA. ii ABSTRACT Table 1: Summary of Structures Survey Results Build Build VDHR Property NR Eligible?
