Project Overview

Introduction The proposed project, henceforth referred to as the Arlington National Southern Expansion (ANCSE) Defense Access Roads (DAR) project, will enable the expansion of Arlington National Cemetery (ANC) to the south for increasing interment spaces for future burials. The project will realign Columbia Pike (Route 244) with a new intersection with S. Joyce Street further to the south; reconfigure the west side of the Columbia Pike and Washington Boulevard (Route 27) interchange from a clover leaf to a tight diamond interchange; and replace Southgate Road with a new segment of S. Nash Street for providing access to and from Joint Base Myer Henderson Hall (JBMHH) and Southgate Road at Foxcroft Heights. The DAR project will complement the future Pentagon 9/11 Memorial Fund (PMF) Visitor Education Center (VEC), which will be located in the southeast quadrant of the future Columbia Pike/S. Joyce Street intersection (and former interchange area). Both projects will be developed outside of the ANC property. The DAR project will support the development of the South Parcel, which is designated as a site east of the existing Virginia Department of Transportation (VDOT) property and south of the realigned Columbia Pike. The South Parcel will serve as the location for a new ANC operations complex (Ops Complex) and a new parking garage for visitors to ANC and the Air Force Memorial (AFM) and for ANC employees. The DAR Project was included with ANCSE project’s National Environmental Policy Act (NEPA) effort, which resulted in an approved Environmental Assessment (EA). The Federal Highway Administration (FHWA) was a cooperating agency in the development and review of the EA. FHWA adopted the ANCSE project’s EA and issued its own FONSI on March 27, 2020. The National Capital Planning Commission (NCPC) served as a cooperating advisory agency to Arlington National Cemetery during the development of the ANCSE EA, which included the proposed DAR Project roadway alignments.

Description of Project Area The ANCSE project site will occupy property formerly utilized as the location for the Navy Annex building and its associated parking areas adjacent to the AFM. The buildings and pavement on this property were demolished in 2012-2013, leaving open green space in its absence. The expansion will also occupy portions of land currently used by Columbia Pike and its interchange with Washington Boulevard, as well as S. Joyce Street and Southgate Road, all of which will be modified as part of this Project. The existing site conditions are shown in Figure 1.

Description of the Proposed Development and Alternatives The ANCSE project involves approximately 70 acres with a primary purpose to increase the capacity for future interments at the cemetery. The ANCSE DAR Project realigns Columbia Pike and the on and off ramps to and from Washington Boulevard for maximizing contiguous interment space south of the current cemetery boundary. The proposed DAR site conditions are shown in Figure 2.

The DAR alignments went through rigorous review before and during the NEPA process in a collaborative approach between the ANC, FHWA Eastern Federal Lands Highway Division (FHWA – EFLHD), the U.S. Army Corps of Engineers, the Virginia Department of Transportation, and Arlington County. This approach took into account citizen input through the NEPA process. The DAR alignments maximize interment space while providing an area for relocation of the Cemetery’s Ops Complex south of Columbia Pike, and for the PMF VEC south of Columbia Pike and east of S. Joyce Street. The relocation of the ANC Ops Complex and a revised site for the PMF VEC further increase the amount of interment space. In addition to the road realignments and replacements, the DAR project will increase multimodal capacity with the inclusion of 8-foot wide sidewalks on both sides of Columbia Pike and a separate 10-foot wide cycle track on the north side of Columbia Pike. New sidewalks will also be located along the reconfigured S. Joyce St. and the new segment of S. Nash Street. To increase safety of crossing pedestrians and bicyclists of Columbia Pike, ADA accessible ramps will be provided along with pavement markings and signage in compliance with the Manual of Uniform Traffic Control Devices (MUTCD), as well as VDOT and Arlington County standards and specifications. For pedestrians crossing between the new ANC Ops Complex parking facility and the AFM and new Cemetery entrance, consideration is being given to adding a HAWK traffic signal (High-Intensity Activated crossWalK beacon) at this crossing, which would stop traffic to allow pedestrians to cross but would also be timed between crossings to allow sufficient vehicular traffic movement. At the time of this report, the DAR project has been developed thru the 75% design submittal. Previous, to this design phase and for the 40% design milestone, a Design Public Hearing was held on February 11, 2020 at the nearby Sheraton Hotel. The purpose of the public hearing was to allow public review and comment on the DAR project. The Public Hearing included a formal presentation and display boards focusing on the roadways, alignments, typical sections, and maintenance of construction traffic phases. Also presented were the results of an Interchange Modification Report (IMR) Update for the Columbia Pike/Washington Boulevard interchange, which included an analysis of multimodal operations considering the improvements at construction completion and in the design year of 2045.The Design Public Hearing also included a presentation and exhibits for the proposed Limited Access Control Change (LACC) request, which requires Virginia Commonwealth Transportation Board (CTB) approval. The LACC will enable increased interment space and the relocation of the ANC Ops Complex. The CTB’s review of the request is scheduled for May 2020. As a separate project, but planned to be incorporated with the ANC DAR Memorandum of Agreement (MOA) with the Cemetery, VDOT, and Arlington County, FHWA – EFLHD will enter into a separate MOA with Arlington County to design and construct a portion of the County’s planned multiuse trail along Washington Boulevard from the project site at Columbia Pike, along the off ramp from Washington Boulevard, and along Washington Boulevard to the Route 110 ramp taper onto Washington Boulevard. A separate application will be submitted to NCPC for the review.

Columbia Pike – The realigned Columbia Pike will have four, 11-foot travel lanes, with curb and gutter that meets the Arlington County standard (18-inch gutter pan). Extra lane width will be provided along the proposed curve between S. Joyce Street and Washington Boulevard. A westbound left turn lane at S. Joyce Street will create an opposing median on the west leg of the intersection, separating the traffic for a portion of Columbia Pike. Eight-foot wide pedestrian sidewalks will be constructed on both sides of the roadway, and a separate 10-foot cycle track will be constructed on the north side that separates pedestrian traffic from bicycle traffic. Pedestrian crossings will be provided at the S. Nash Street and S. Joyce Street intersections, and at the Washington Boulevard off ramp intersection with Columbia Pike. It is anticipated that for PMF VEC visitors will make use of these crosswalks to access the Pentagon 9/11 Memorial. A pedestrian crossing with a HAWK signal to facilitate crossings during heavy vehicular traffic, is proposed to be located for access between the ANC Ops Complex parking garage and the entrance to the AFM and Cemetery. The pedestrian sidewalk and cycle track will be combined at the Columbia Pike eastern terminus near the underpass to the Pentagon. The separate multiuse trail project will connect here and follow the off ramp from Washington Boulevard and along Washington Boulevard between the Cemetery Boundary Wall and roadway. The multiuse trail will likely require being located on both Cemetery property and VDOT right of way (ROW), given that the area between the existing roadway and VDOT ROW limits is heavily encumbered with utilities.

The agreed-upon proposed typical section for the DAR project’s realigned Columbia Pike is shown in Figure 3.

South Joyce Street – The reconfiguration of S. Joyce Street will include four travel lanes with a median and a northbound left turn lane onto westbound Columbia Pike. The outer lanes will have Arlington County standard curb and gutter and will accommodate bus transit. An 8-foot wide sidewalk will be provided on the west side of S. Joyce Street and a 10-foot wide shared use path will be provided on the east side. The “T” intersection with Columbia Pike will be configured with two northbound left turn lanes and one northbound right turn lane.

South Nash Street – The new segment of S. Nash Street will include two 11-foot wide travel lanes with a 10-foot wide shared use path on the west side. South Nash Street will provide a connection to the JBMHH Gate and to Southgate Road at Foxcroft Heights. A short portion of Southgate Road will be reconstructed which will result in an increase to the area for Foxcroft Heights Park.

Proposed Schedule The project schedule is as follows: 75% Design: Provided April 23, 2020 for stakeholder review. 100% Design: Completion expected late September/October 2020 Solicitation: December – February 2021 Construction: April 2021 – October 2023

Preliminary Project Cost Estimate Current Preliminary Project Construction Cost Estimate at the 75% Design is $60 million.

Outreach and Coordination Public Engagement/Coordination with State, Federal, and Local Jurisdictions Early agency coordination was accomplished in accordance with the National Environmental Policy Act (NEPA) process through cooperating agency invitations to five agencies with legal interest and/or jurisdiction over the Proposed Action, which included FHWA-EFLHD, EPA, NCPC, VDOT, and Arlington County. All five agencies accepted and participated in the NEPA process. A cooperating agency kick-off meeting was held on March 9, 2016, and coordination was conducted at key points in the process. A Notice of Intent to prepare an EA was published in the Federal Register on April 20, 2016. ANC issued a press release, and public notices were also published in the Washington Post, the Washington Times, and the El Tiempo Latino newspapers, and on ANC’s and the US Army

Corps of Engineers’ (USACE) websites. Brochures regarding the Proposed Action were mailed to approximately 250 property owners, agencies, and civic leagues located near the project site and Columbia Pike. ANC and USACE also posted information on their respective websites for the expansion project during the NEPA process. On April 27, 2016, a press conference and an open-house-style NEPA public scoping meeting were held at the Sheraton Pentagon City, Arlington, Virginia. Representatives from USACE, ANC, the five cooperating agencies, and consultant’s staff, as well as a Spanish-language interpreter were available to answer questions and obtain comments. Project brochures were also available. More than 75 people attended the scoping meeting. The public had an opportunity to provide written comments during the meeting, as well as throughout the comment period from April 20 through May 31, 2016. In accordance with Section 106 of the National Historic Preservation Act (NHPA), ANC also used the NEPA scoping process to notify 50 potentially interested agencies (including State Historic Preservation Office), other organizations (including Native American Tribes), and individuals of the scoping meeting, and to invite them to be consulting parties with respect to cultural and historic properties. Six of these groups responded affirmatively: National Park Service (NPS) – George Washington Memorial Parkway; VDOT Northern Virginia District; Arlington County; Catawba Indian Nation; Arlington Historical Society; and the PMF. The Draft EA was released on August 16, 2018 for public review, and a public meeting was held on August 22, 2018. Fifty-one people attended the public meeting. The public had an opportunity to provide written comments during the meeting, as well as throughout the comment period from August 16 through September 22, 2018. Approximately 157 comments were submitted. Approximately 90% of the comments related to the dimensions, design, and safety of the bicycle and pedestrian trails. All public and agency comments were addressed in Appendix A of the Final EA. USACE released the Final EA and Draft Finding of No Significant Impact (FONSI) on August 30, 2019 for public review. Comments received on the Draft FONSI were responded to and included in release of the Final FONSI. ANC signed the Final FONSI December 9, 2019 following completion of the Section 106 Memorandum of Agreement between the State Historic Preservation Officer, Air Force District of Washington, and ANC. FHWA adopted the Final EA and issued its own FONSI on March 27, 2020, following completion of an IMR Update, letter of Arlington County support, and VDOT approval of the IMR Update, which reviewed traffic impacts related to the location of Amazon’s second North American Headquarters site in Crystal City and Pentagon City. The VDOT review looked at the function of the proposed interchange between Columbia Pike and Washington Boulevard, and looked at traffic performance for the new intersections of Columbia Pike with S. Joyce Street and S. Nash Street, for the entrance to the ANC Ops Complex, and for multimodal operations related to bus transit, pedestrians, and bicycles extending to year 2045. A Design Public Hearing (DPH) for 40% design was held for the DAR project on February 11, 2020 at the Sheraton Pentagon City, Arlington, Virginia. The DPH was advertised in the Washington Post, El Tiempo Latino, Arlington Now, and Arlington Sun Gazette Newspapers, as well as in more than 5,000 mailed

postcards to local citizens of the project. The DAR team issued a press release about the DPH, and Arlington County emailed the press release to its citizens. In addition, project information was posted to a FHWA website with weblink information provided in the notices and postcards, and a Public Hearing Brochure was available to attendees at the Hearing. At the Design Public Hearing, there were ninety-seven (97) citizens who attended the meeting per the sign in sheets. There were 16 written comments received at the hearing. There were eleven (11) oral comments recorded by the court reporter at the meeting. In addition, twenty-one (21) emailed comments and one (1) call-in comment were received by FHWA. A majority of the comments included constructive suggestions for the project’s design and construction. Several comments expressed enthusiastic support for the project. There were no comments expressing opposition to the project. FHWA’s responses to the public comments have been posted on EFLHD’s project website.

Architectural and Design Program The design includes relocation of utilities from out of the proposed Cemetery expansion site to the Columbia Pike ROW corridor, and any other corridor as required. Utility stub-out connections will be provided to the new ANC Ops Complex, the AFM, and Cemetery Columbaria area, as well as the PMF VEC. Additionally, temporary utilities will be provided for the current ANC Ops Complex until the new facility is constructed, given that most existing utilities within the Cemetery expansion site will be removed by the DAR Project. The DAR Project will also construct an underpass between the expanded Cemetery site and the new ANC Ops Complex. In support of the Ops Complex, the DAR project will construct large retaining walls bordering the VDOT Maintenance Compound on the west side of the South Parcel and along the I-395 ROW on the south side. This effort will provide a near- “pad ready” site for the ANCSE Project to begin construction for the new Ops Complex while the DAR project work is ongoing. Landscape Plan The overarching goal of the Cemetery’s expansion project is to create a contiguous extension of the existing cemetery for additional interment areas to the south. This means building a landscape of rolling terrain, tree-shaded grounds linked with a clear, functional, internal curvilinear road network. Related to the above context, the landscaping for the DAR Project roadways is being planned and designed in collaboration with Arlington County and the Cemetery. On the north side of Columbia Pike there will be two landscape buffer strips that will contain tree plantings, and one of the buffer strips will also have streetlights for lighting of the pedestrian walkway and cycle track. On the south side, there will be one buffer area for both street trees and streetlights. Landscaping is also planned for S. Joyce Street and S. Nash Street, with additional landscaping buffering between Foxcroft Heights and the Cemetery on the west side of a retaining wall and a buffer area between the shared use path and roadway. Landscaping is planned in both buffers along S. Joyce Street. Figure 6 shows the DAR project’s landscape plan in the context of the ANCSE project.

Transportation and Circulation A Transportation Management Plan (Type C) is required for the DAR project, in accordance with VDOT requirements, which will include a temporary traffic control plan (maintenance of traffic or MOT plan), a public communications plan, and a transportation operations plan. The following traffic control (MOT) plan has been outlined as part of the 75% Design:

Columbia Pike and other roadways The roads have been described previously in this report. Transportation Management During Construction The 75% Design plans contain detailed traffic control phasing along with a supporting temporary traffic management narrative, with typical sections and supporting cross-sections showing the work areas, active lanes, and pedestrian and bicycle facilities for detouring of traffic (and pedestrians and bicycles) around the work areas. It is the goal of the DAR project, as captured in the plans, to detour all traffic, including pedestrians and bicyclists away from the Columbia Pike construction. To accomplish this, S. Nash Street will first be constructed including two additional temporary lanes for the detour of buses and vehicles from Columbia Pike onto these lanes, and then to existing Southgate Road, and to other temporary pavements including segments of the existing Columbia Pike ramps. This route will also include additional widening to facilitate easier movements by buses and trucks to navigate the sharp turns the detour route would otherwise have. Because of the need to significantly raise S. Joyce Street at its intersection with Columbia Pike, temporary pavements will be required to detour S. Joyce Street traffic around this work. During construction, access will be maintained to the existing ANC Ops Complex, the AFM, the VDOT Maintenance Compound, and to the areas served by the beginning and ending points of construction for Columbia Pike and S. Joyce Street. The plans contain a Temporary Traffic Management Plan (TMP) that provides emergency contacts and other necessary information required to preserve a safe detour for the traveling public around and through the work zones. This TMP and temporary traffic phasing plans will be refined with the subsequent design milestones, i.e., the 95% and 99% design milestones, which will come after the current 75% design milestone, leading to Final Approved Construction Documents.

Perimeter Security

During construction, work zone perimeters will be delineated by temporary construction fencing, and the active roadway will be delineated by work zones, with barriers, barrels, cones, signage, and temporary traffic markings.

Environmental and Historical Considerations Historic Preservation Section 106 of the National Historic Preservation Act (NHPA) mandates that federal agencies consider the impact of their undertakings on historic properties within the project’s Area of Potential Effect (APE). This project’s APE can be seen in Figure 7 below.

Figure 7: Area of Potential Effect The project would result in adverse effects to the AFM site and the National Register of Historic Places (NRHP) listed ANC historic district, given that both the southern boundary wall and the Ops Complex are considered contributing elements. The adverse effects were resolved through mitigation measures stipulated in a Memorandum of Agreement, which has been finalized. The impacts include the removal of the boundary wall along Southgate Road, conversion of part of Patton Drive to a pedestrian trail and relocation of the Ops Complex, all contributing to the ANC NRHP-listed historic district; and modification of the Air Force Memorial site, which has been determined NRHP eligible. The Memorandum of Agreement between the State Historic Preservation Officer, Air Force District of Washington, and ANC resolves adverse effects to cultural and historical resources. This Memorandum of Agreement includes

Page 16: ANC Defense Access Road Project Report · 2020. 5. 15. · Preliminary Project Cost Estimate . Current Preliminary Project Construction Cost Estimate at the 7 5% Design is $ 60 million.

the mitigation necessary to offset the adverse effects, and is located in the Appendices of the EA. With the conclusion of this agreement there will be no significant impacts to cultural resources.

Additionally, an impact assessment of thirty vantage points, both inside and outside of ANC, concluded that there would be no adverse visual effects to any NRHP listed or eligible properties resulting from the project.

The DAR Project will address mitigation requirements related to archaeological and human remains discoveries during construction in the project Special Contract Requirements. The requirements consist of Stop Work conditions and reporting of the discoveries to the Contracting Officer’s construction oversight agents and to other contacts for further actions to be taken. Natural Resources Water Resources The project area was investigated for the presence of jurisdictional waters and wetlands using the three criteria espoused by the USACE – hydric soils, vegetation, and hydrology. The investigation found no evidence of wetlands or surface waters in the project area. Geotechnical investigations discovered groundwater at the project site. Due to the soil conditions, specifically the dense clay layer, there are perched groundwater conditions resulting in groundwater being found close to the ground surface, as shallow as 4-8 feet below ground surface (bgs) in some locations. The depth to the lower groundwater table, based on soil samples, ranged from approximately 16 feet to 56 feet bgs. The geotechnical report indicated the depth of groundwater, especially perched groundwater, is expected to fluctuate with the seasons, variations of rainfall, and/or adjacent construction activities such as dewatering and pumping.

All development would be planned and designed to avoid sensitive areas and would be consistent with the Virginia Coastal Zone Management Program to the maximum extent practicable. There would be no direct impacts to surface water bodies, groundwater, floodplains, or wetlands. There would be a significant reduction in impervious surfaces from the 2006 condition, resulting in a reduction of stormwater runoff and pollutant loads. Additionally, the potential for the project to impact groundwater is negligible. Biological Resources The project area includes maintained fields, manicured lawn, grassy highway ROW; the Columbia Pike/South Joyce Street/Southgate Road roadway system, parking areas, highway ramps to VA-27, the Operations Complex, and the AFM. Based on Google Earth aerial photography, there are scattered forested uplands, in the form of linear bands of trees lining the steep embankments along Southgate Road, Columbia Pike, and I-395. There are also scattered young trees along the slope of the AFM. Most of the existing trees in the action area are planted or are pioneer species, rather than remnants of natural forests. In addition, numerous invasive species are present in the wooded areas.

There are no federally-listed threatened or endangered species, nor any critical habitat within the project

Page 17: ANC Defense Access Road Project Report · 2020. 5. 15. · Preliminary Project Cost Estimate . Current Preliminary Project Construction Cost Estimate at the 7 5% Design is $ 60 million.

area. The Virginia Department of Game and Inland Fisheries identifies state listed species which have the potential to occur within a three-mile radius of the project area. Of these listed species, the Virginia Department of Conservation and Recreation (VDCR) indicated the wood turtle has documented occurrences in Four Mile Run, a stream located approximately 1.5 miles south of the project area. Because the primary habitat requirement is the presence of water, and there are no surface water bodies present in the project area, the wood turtle would not be impacted by the project.

The bald eagle is protected under the American Bald and Golden Eagle Act and Migratory Bird Treaty Act, and is a state-listed threatened species. The bald eagle is known to or have the potential to occur in the project area. However, the nearest documented nest is over two miles away from the Southern Expansion area and would not be affected by the project. USFWS provides a list of other migratory birds that could occur within the vicinity of the project area.

There would be no impact on any federally-or state-listed threatened or endangered species. The project site was disturbed previously and does not contain natural habitat. Regardless, there would be a temporary disruption to wildlife inhabiting the Southern Expansion site. Upon the start of construction, wildlife species instinctively would move to adjacent areas. The temporary impact would be offset at the project completion by providing permanent positive impacts with new landscaping including turf, trees, shrubs, and other plant material in planting beds that will be native to and compatible with the geographic region. There would be a net increase in vegetation as native wildlife species re-inhabit the site upon completion.

BMPs would be used during construction to avoid or minimize introducing invasive species inadvertently. ANC’s Invasive Species Management Plan – prepared by the ANC horticulturalist and master arborist provides recommendations for the long-term management of invasive species.

Energy and Sustainability The project supports the Army’s sustainability policies by: reducing the amount of impervious surface and increasing the amount of open space when compared to the 2006 conditions, which included the removal of Navy Annex facilities; reusing previously developed land; using Best Management Practices (BMPs) during construction; and using a location that provides multimodal transportation options.

The project includes opportunities for sustainable design elements. Also, the project will provide the important asset of extending the cemetery’s longevity for future generations. Finally, the project will not stimulate additional development.

Public Realm and Viewsheds Temporary effects: Construction activity would occur within the entire project area. Heavy equipment would be used for many features of the roadway construction and cemetery expansion. Construction materials would be staged onsite. All of this would represent a temporary impact to aesthetic and visual resources. Permanent effects: For the ANCSE Project, the AFM and the slope that it sits upon serve as a visual wedge separating the eastern and western areas of the Southern Expansion Site. This works to an advantage to obscure the southwest quadrant from view (the area of the proposed Ops Complex), and to visually interrupt the interment area within the Southern Expansion Site. This provides a future benefit whereby more than one interment would be able to occur simultaneously within the Southern Expansion.

Also, the removal of the Ops Complex from the current location would provide an uninterrupted view of the existing ANC interment area to the north from the AFM and the southeast quadrant. This is important as it conforms to the character of the cemetery as an important feature of its historic district designation:

Under Criterion C of the NRHP, the ANC historic district reflects “design characteristics associated with the picturesque/rural cemetery movements or the establishment of national cemeteries” and a picturesque landscape of gently rolling hills following natural contours in an important aspect of the design (Smith et al. 2014).

The viewshed study completed as part of the Final Environmental Assessment (EA) (August 2019) concluded that no adverse effects are anticipated, either on the surrounding area or the historical views or vistas within or outside of the cemetery that contribute to its NRHP status. The viewshed is also being addressed through the Section 106 process and the finalization of the MOA.

All measures to preserve aesthetic quality would be carefully designed and maintained so that they are fully compatible with the project purpose and would not compromise the safety, integrity, or function of the project. There would be a long-term positive impact on the viewsheds.

For the DAR Project the roadways, realigned and replaced, will be shorter with an overall reduced impervious area. Intermodal transportation, that takes into consideration pedestrian and bicycle access will be improved. Stormwater Management The project is subject to meet requirements established in Section 438 Of Energy Independence and Security Act (EISA), design objective two, restoring pre-development hydrology. Virginia DEQ’s Virginia Stormwater Management Plan (VSMP) is the authorizing agency for land disturbing activities performed

Page 19: ANC Defense Access Road Project Report · 2020. 5. 15. · Preliminary Project Cost Estimate . Current Preliminary Project Construction Cost Estimate at the 7 5% Design is $ 60 million.

by federal entities. The project will address quantity control and quality control of stormwater runoff from the site as required by Virginia DEQ. In addition, the site is subject to the Chesapeake Bay Preservation Act since the site is in the Chesapeake Bay watershed and the area of land disturbing activities exceeds 2,500 square feet. Therefore, VSMP regulations take precedence over EISA 438 regulations. The stormwater management design is developed to effectively collect, convey, treat, and release the stormwater runoff from the proposed site following the requirements of UFC 3-201-01, UFC 3-201-10, Section 438 of the EISA, Virginia DEQ Stormwater Management Regulations, and VDOT Drainage Manual. The primary goal for stormwater management is to honor the existing drainage characteristics of the site to the maximum extent technically feasible while following low-impact site development strategies. Any permanent BMP’s proposed for the site will comply with Virginia approved stormwater BMP Standards and Specifications.
