Chapter 2 LOCALLY PREFERRED ALTERNATIVE 2.0 LOCALLY PREFERRED ALTERNATIVE This chapter describes the recommended Locally Preferred Alternative (LPA) for Urban Ring Phase 2. The LPA is the result of the evaluation of nine Build Alternatives and three Hybrid Alternatives that are described and evaluated in Chapter 3. Section 2.1 is a detailed description of the LPA, Section 2.2 describes the transportation benefits of the LPA, Section 2.3 describes the BRT vehicle fleet size and maintenance facility, Section 2.4 describes environmental impacts and their mitigation, and Section 2.5 provides a summary of estimated capital and operating costs. The LPA is an integrated system of transit improvements that meets the need to provide better circumferential transit service in areas of Boston and the neighboring municipalities of Brookline, Cambridge, Chelsea, Everett, Medford and Somerville. The LPA would pass through a corridor where the existing radial MBTA rapid transit and commuter rail lines fan out, and transit access to residential neighborhoods and activity centers becomes more limited. Many of these areas contain high concentrations of environmental justice populations and households without automobiles that depend on transit for access and mobility. The LPA also meets the needs of regional travelers connecting to and from the Urban Ring corridor, enabling them to avoid a trip to downtown to transfer services. The LPA would create more direct transit routes for large numbers of existing MBTA riders, as well as attracting new MBTA riders who divert from automobiles and private shuttle modes. It would also attract additional riders who combine walking or bicycling trips with transit. More than 36,850 people currently ride private shuttle buses daily in the project corridor because the existing public transit connections do 1 not meet their needs. By increasing transfer opportunities and decreasing the need for many transit riders to travel into downtown Boston and transfer to an outgoing line to reach their destination, the LPA would also reduce congestion on other heavily used MBTA rapid transit lines. Intercepting transit riders outside the congested downtown core of Boston would improve travel times and convenience for commuters and travelers throughout the region, thereby attracting more transit riders to the system and reducing the number of miles traveled (and air pollution emitted) by automobiles. Unlike other transit projects that typically consist of one line or service, the Urban Ring Phase 2 LPA is a system of several different types of transit lines and stations. The major components are: • Five Bus Rapid Transit (BRT) routes covering a 25-mile highly urbanized mile-wide corridor with nearly a half million residents in the year 2030; • 36 stations2 ranging from street-level shelters to larger stations with joint development opportunities; • 19 intermodal transfer points that would create connections with all existing MBTA rapid transit lines, as well as most commuter rail lines and several major bus hubs. Public, stakeholder, and agency involvement has been central in the development of the LPA. The project’s Citizens Advisory Committee (CAC) has continued to serve as a principal channel for public and stakeholder participation to supplement EOT’s periodic major public meetings on the project and its briefings for neighborhood and institutional groups. EOT has worked closely with the CAC and its subcommittees throughout the alternatives analysis process to provide information and revise the design of alternatives in response to public and stakeholder concerns. Similarly, EOT has engaged a wide range of agencies at the municipal, state and federal levels with a stake in the successful outcome of this project. It is this active involvement and coordination that has produced a Locally Preferred Alternative that successfully meets the access needs of the people and businesses of Greater Boston. 1 2 Private shuttle ridership information was collected from shuttle providers, including MASCO, Charles River Transportation Management and Boston Medical Center Shuttle Service in 2007. For more private shuttle ridership information refer to Table 4-8: Summary of Private Shuttle Daily Ridership by Owner in Chapter 4. The precise number of stations may change based on final Allston alignment. Urban Ring Phase 2 RDEIR/DEIS Page 2-1 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE 2.1 Locally Preferred Alternative Description The analysis of the alternatives and their respective benefits, costs and impacts has enabled the selection of a recommended LPA for the project corridor. The LPA is a system of transit services and stations that would increase circumferential mobility within the project corridor and make transit significantly more attractive by making trips more direct and less time-consuming for travelers throughout the greater Boston region. Table 2-1 shows some key characteristics and performance measures of the Urban Ring Phase 2 LPA.

(4) This is based on the FTA metric of cost per user benefit hour, a measure of annualized capital and operating and maintenance costs divided by the aggregate time savings provided to transit riders by the project. The costeffectiveness calculation for the LPA and the project alternatives are preliminary, and are based on travel demand modeling results and cost estimates that do not yet have FTA approval. Ridership and cost data will be formally reviewed by FTA during a request for New Starts Preliminary Engineering approval. Urban Ring Phase 2 RDEIR/DEIS Page 2-2 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE One of the central performance measures, trips that are projected to use the Urban Ring Phase 2 in the horizon year of 2030, has been developed using the Boston Region Metropolitan Planning Organization’s regional travel demand model. This is the same model, with the same underlying demographic and travel network assumptions, which is used to analyze other potential transportation projects in the Boston Region, as well as the proposals for the Boston Regional Transportation Plan. The model’s projections for the Urban Ring Phase 2 ridership have not yet been reviewed and approved by the Federal Transit Administration. EOT will continue to work with FTA on the review of these projections as the Urban Ring Phase 2 progresses toward a New Starts program application. The LPA would be served by the following five overlapping BRT routes:3 • BRT 1 Airport Blue Line Station - Kendall Square; • BRT 2 Logan Airport (West Garage) - Wellington Station; • BRT 5 Sullivan Square - Ruggles Station; • BRT 6 Harvard Square - JFK/UMass Station; and • BRT 7 Yawkey Station - Mystic Mall (Everett Avenue). The LPA described in this chapter entails a single, final preferred alignment and service plan in most segments of the corridor. However, there are five major issues (related to uncertainty about timing, actions by others, and/or the project funding environment) that necessitate a recognition of routing options, contingent alignments, or the potential for refinements to the LPA alignment or implementation plan. The following are the LPA elements with uncertainties, and the principal sources of uncertainty: • Railroad Coordination. The preferred alignment would require acquisition of abandoned railroad tracks and coordination on BRT operation near commuter rail or freight tracks. The Commonwealth of Massachusetts’ recent agreement with CSX Transportation sets the stage for the Commonwealth to purchase and take control of several key railroad properties, subject to completion of the other elements in the overall plan. This is expected to simplify the rail coordination issue. • Allston Connection. Although the Urban Ring project has been in planning for many years, the potential BRT connection to Allston is a new proposal that has not yet undergone formal public review and comment. In addition, there are a number of major issues related to the Allston BRT connection that will require further review and consideration. One potential Urban Ring Phase 2 alignment would pass beneath the Massachusetts Turnpike viaduct and through CSX Transportation’s Beacon Park Yard railroad facility. It is expected that the Massachusetts Turnpike viaduct will require significant repairs in coming years, and that the CSX railroad operations will be subject to consolidation and relocation. Further, the City of Boston is undertaking a major community planning study, at the same time that Harvard University is conducting a master plan for a major expansion of its Allston campus. Both of these planning efforts are expected to influence potential Urban Ring Phase 2 connections. As a result of these factors, the project recommendations include a range of alternatives for making connections in Allston that are designed to maintain flexibility and enable consistency with different future conditions. • Fenway/LMA Tunnel. The proposed 1.5 mile tunnel through the Fenway/LMA is projected to cost $1.7 billion, or approximately two thirds of the project’s $2.4 billion capital cost (in 2007 dollars). This major investment is warranted by the LMA’s dense concentration of jobs and travel demand, along with its limited and highly congested roadways in close proximity to sensitive natural and historic 3 BRT route numbers 3 and 4 were included in alternatives analysis, but have been eliminated from the LPA as separate routes in order to optimize alignment, service characteristics, and cost-effectiveness. Urban Ring Phase 2 RDEIR/DEIS Page 2-3 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE resources of the Fenway neighborhood. A wide range of tunnel alternatives were developed and evaluated during the course of the RDEIR/DEIS, leading to a preliminary recommendation for Fenway/LMA tunnel alignment, as well as an assumption about construction method (for cost estimating purposes, based on best available information at the conceptual level of planning and engineering). EOT will use this environmental filing to continue to solicit feedback from the general public, corridor residents, municipalities, public agencies, elected officials, and other project stakeholders regarding tunnel alignment and construction method. EOT will consider this feedback, along with more detailed technical information developed during preliminary engineering, in order to ensure an optimal tunnel proposal from the perspective of cost-effectiveness, engineering feasibility, and abutter benefit and impact. In order to provide adequate time to identify necessary funding and to enable interim bus service improvements, an interim surface route to serve this area is also being investigated. • Orange Line Connection/Mystic River Crossing. There are a number of challenges in the northern segment of the LPA alignment, generally between Everett and Sullivan Square. These include environmental impacts to crossing the Malden River, congestion on Revere Beach Parkway/Route 16, and challenges to providing dedicated right-of-way. New planning efforts in the vicinity of Sullivan Square by the City of Boston may facilitate a review of the alignment in this segment of the corridor. • Financial Constraints. Overarching all of these issues is the issue of project costs and financial feasibility. The project proposed in this RDEIR/DEIS has high benefits, but also high costs. As a result, there is significant uncertainty about the Commonwealth’s ability to advance the Urban Ring. There is tremendous competition for limited federal and state funds, including a number of other major transit expansion projects, such as the State Implementation Plan projects (Green Line Extension, 1,000 park–and-ride spaces, and Fairmount Line), as well as the Silver Line Phase III and the South Coast Rail project. These issues are described in detail in the relevant sector descriptions in Section 2.1. EOT is now performing a study for the Allston area that entails coordination with the City of Boston, Harvard University, Boston University, the Allston neighborhood, and other stakeholders. The preliminary engineering findings of that study will be used to further define and evaluate the potential Urban Ring LPA alignments and configurations. Modifications for other areas will be evaluated as the preliminary engineering phase of the Urban Ring project progresses, with a particular focus on the proposed tunnel alignment in the Fenway/LMA segment of the corridor. Figure 2-1 shows the proposed alignment of LPA and Figure 2-2 shows the BRT routes that make up the LPA.

BRT is a transit mode that employs modern bus vehicles within a system of coordinated infrastructure and service enhancements that enable the buses to operate more like rapid transit service. Chapters 3 and 4 discuss the bus rapid transit elements and systemwide transit feature options. The Urban Ring Phase 2 LPA includes the following important BRT project elements: • Dedicated roadway – This refers to roadway space that is restricted for special transit use. In the Urban Ring LPA, dedicated roadway for BRT use is available in the form of “busways,” or roadways reserved for bus-only use (either surface busways or busway in tunnel), and bus lanes on existing roadways that also carry general traffic. The proposed bus lanes in the LPA would not have adjacent on-street parking, which can create “friction” from parking entry and exit, as well as blockage from double-parking. Bus lanes would be designated by pavement markings and signage. • Bus queue-jump lanes – These are a special type of bus lane that is most suited to congested roadways with limited opportunity for long stretches of continuous bus lane. Bus queue-jump lanes are short priority lanes for buses in advance of a signalized intersection; these are typically combined with traffic signal priority improvements to allow the higher-capacity vehicles to move through the intersection in advance of the general traffic queue when a traffic signal turns green. This reduces the delay caused by the signal and improves the operational efficiency of the transit system. • High-frequency service – In peak periods, proposed Urban Ring Phase 2 service would range from every 10 minutes to as often as every 3 minutes in heavy demand segments of the corridor. Station dwell times would range from 15 to 30 seconds, with 15 or 25 second dwell time at most stations. • High capacity, low-emission vehicles – Vehicles would be 60-foot articulated buses powered by diesel-electric hybrid engines, with low emissions and low floors for easy, rapid boarding. The BRT vehicles would be configured with passenger circulation enhancements that can have important impacts on dwell time, capacity, passenger comfort, and community and rider acceptance. Conventional 40-foot transit buses typically can carry approximately 50-60 passengers, while 60-foot articulated buses of the type assumed for Urban Ring Phase 2 have capacities of approximately 8090 passengers (depending upon configuration of doors and seats). Diesel-electric hybrid engines provide improved performance and fuel economy with reduced emissions. Hybrid engines are capable of using low-emission fuel on city street and electric power in the tunnels. • Widely-spaced, substantial and recognizable transit stations, rather than bus stops – Four BRT station prototypes were developed based on specific site conditions. They include stand-alone station, joint development, intermodal and underground tunnel prototypes. The Urban Ring station prototypes include new features, including weather protection, security cameras, ITS features, fare vending machines and vertical icons that make stations both user-friendly and identifiable from a distance. (See Chapter 3 for more detailed description of the station prototypes.) • Advanced communications – This includes technology that reduces delay for BRT vehicles at traffic signals, provides real-time traveler information, and enforces bus only use of dedicated BRT lanes, busways and tunnels. BRT vehicles typically utilize Intelligent Transportation Systems (ITS) technology to improve reliability, increase safety, and reduce travel time on a BRT system. ITS technology consists of different combinations of technologies such as Automatic Vehicle Location (AVL), Automated Scheduling and Dispatch (ASD), and Transit Signal Priority (TSP). These technologies provide real-time schedule information and inform passengers of any delays incurred at stations. TSP systems that can be facilitated with timing adjustments on every signal cycle are appropriate with large numbers of buses and highly congested conditions. A detailed description of the signal priority system is provided in Chapter 4. The Urban Ring project may also be able to use photo and video enforcement technology (bus-mounted or fixed cameras) for automatic enforcement of dedicated bus lanes, busways and tunnels (depending upon technology advances and Urban Ring Phase 2 RDEIR/DEIS Page 2-7 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE legal/regulatory environment). Automated enforcement technology is described in Chapter 3, Section 3.11. • Modernized fare collection system – This includes electronic and mechanical fare collection systems that maximize the boarding efficiency of the BRT buses. It is assumed that Urban Ring Phase 2 BRT vehicles would utilize equipment and technology for fare transactions based on embedded-chip smart cards (consistent with the MBTA Charlie Card system). Figure 2-3 and Table 2-2 provide an overview of corridor segments. These segments correspond to the detailed descriptions of the LPA alignment in Sections 2.1.1 – 2.1.11. The following sections describe the key characteristics of the LPA in each of the 11 geographic sectors of the project corridor, beginning in East Boston at Logan Airport and proceeding counterclockwise (see Figure 2-3 for Segments and Sectors Map). The LPA sector descriptions include a summary of the sector area, the Urban Ring stations in the sector, the Urban Ring service characteristics, transportation issues, environmental issues, and economic development issues. Detailed maps of the LPA alignment and the route structure of the five BRT routes are provided at the end of this section. 2.1.1 Sector 1: East Boston/Logan Airport Sector 1 of the LPA alignment extends from the I-90 Ted Williams Tunnel to the crossing of Chelsea Creek at Chelsea Street in East Boston. It uses existing regional highway and Massport roadways in combination with a proposed new bus and commercial vehicle only facility located in the abandoned railroad right of way between Logan Airport and the approach to the Chelsea Street Bridge. See Figures 2-4 and 2-5 for Sector 1 alignment of the LPA. The key transportation features of Sector 1 include access to the centrally located West Garage at Logan Airport, connection to Airport Station on the Blue Line, and travel in the proposed restricted-access East Boston Haul Road, which would improve travel time and reliability by allowing buses to avoid general traffic congestion in and around the airport and on neighborhood streets. Stations. The LPA includes two stations in this sector that would be located at: • Logan West Garage; and • Airport (Blue Line connection). These stations would provide connections with four MBTA bus routes and Massport shuttles, as well as one connection with the MBTA Blue Line (at the Airport). Refer to Table 2-3 for list of connections. Urban Ring Service. Urban Ring service would be available on three BRT routes: • Route 1 - Airport Station to Kendall Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) • Route 2 - Logan West Garage Station to Sullivan Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) • Route 7 – Yawkey Station to Mystic Mall (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) All three routes would serve Airport Station, which is directly accessible to the East Boston neighborhood via Bremen Street, and has direct connections with both the Blue Line and various Massport shuttle buses. The BRT2 route only would serve the two stations in Sector 1: Airport West Garage Station would be served via a new bus-only connection to a station stop at the ground floor of the existing West Garage with vertical circulation to the pedestrian bridge and moving sidewalk network that connects with individual airport terminals; and Airport Station.

The mixed traffic portion is primarily the I-90 Williams Tunnel and Logan Airport roadways, while the dedicated right of way portion is in the proposed East Boston Haul Road. Average travel speeds would be approximately 16 mph in each direction. Demographics. An estimated 22,100 people will live within a one-half mile walk of one of these two stations, of whom a majority of residents live within TAZs that meet regional Environmental Justice criteria (based on current population characteristics), and 11,000 people are expected work within one-half mile of a station (an area that includes Logan Airport and its employees) by 2030, the project horizon planning year. A traffic analysis zone (TAZ) is a defined geographic area used in transportation network modeling. The criteria for establishing TAZs include homogenous land use, street system and natural barriers, and other factors. There are 2,727 TAZs in the CTPS regional transportation model being used for this project. Each TAZ has population and employment characteristics that are converted to vehicle trips which are then assigned to the local and regional roadway network. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. More detailed summary information is provided in Chapter 4 (Transportation) and Chapter 5 (Environmental). Transportation Issues • Coordination with implementation of the East Boston Haul Road, a proposed restricted use roadway in the former railroad right of way between the Airport Service Road and Chelsea Street. This roadway is proposed to provide airport-related commercial vehicles, airport-related shuttles, and other transit vehicles (including the Urban Ring) with access between Logan Airport and Chelsea that avoids the heavy congestion in Day Square and the Neptune Road corridor. The service plan for the three proposed Urban Ring BRT routes combined (totaling approximately one transit vehicle every three minutes during peak periods in each direction) in combination with the fairly low demand by other vehicles should allow good travel times and vehicle operations, with no capacity issues. This shared-use approach allows multi-use benefits and should improve the environmental benefits to the East Boston neighborhood. Additional analysis is needed to finalize appropriate design of the facility and determine cost-sharing as appropriate. • Logan Airport West Garage BRT Station Layout. Several optional route and station location options were coordinated with Massport, which controls planning and ground transportation at Logan International Airport. Massport has expressed a preference that the Urban Ring BRT service provides a single centralized station location rather than serving all the individual terminals, and that the location be within the ground floor of the existing West Garage where it Urban Ring Phase 2 RDEIR/DEIS Page 2-10 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE can take advantage of existing pedestrian bridges and moving sidewalks connecting to the individual airport terminals. Further details of the station layout and circulation will be defined in coordination with Massport in subsequent phases of project development. Environmental Issues • Sites where hazardous materials have been identified are limited to five locations where underground storage tanks have been identified or are listed as unclassified sites. • Coordination with the East Boston Greenway. During the DEIR process coordination meetings were held with East Boston and Greenway stakeholder groups. The key coordination issue with the East Boston Greenway, an existing shared-use path with a proposed extension, is where the proposed Greenway extension and the planned busway pass beneath Route 1A. A conceptual engineering plan was developed that shows the separation of uses and the location of a signal protected at-grade pedestrian and bicycle crossing at the intersection of the busway with the Airport Service Road. As the respective projects advance, further coordination on right-of-way acquisition and design details will be necessary to ensure that the compatibility established at the conceptual level continues and is further enhanced. 2.1.2 Sector 2: Chelsea Sector 2 of the LPA alignment crosses Chelsea Creek using the Chelsea Street Bridge (proposed for reconstruction by others) and passes through East Chelsea on Eastern Avenue parallel to the waterfront before entering an exclusive busway in the abandoned rail corridor. It then parallels the south side of the existing MBTA Rockport Commuter Rail line in a busway that extends westward through Everett. See Figure 2-5 for Sector 2 alignment of the LPA. The busway, which extends through most of Chelsea, would provide improved travel time and reliability over the general traffic roadways, which carry high truck volumes and are often congested. The alignment also provides a more direct route than the circuitous existing roadways. New or upgraded signals would be provided at grade crossings to improve safety and operations. The connection with commuter rail at the Downtown Chelsea Station would improve service and connections for riders to and from Chelsea. Stations. The LPA includes three stations in this sector that would be located at: • Griffin Way; • Downtown Chelsea (connections to commuter rail); and • Mystic Mall. These stations would provide connections with five MBTA bus routes and the MBTA Newbury/Rockport Commuter Rail Line at Downtown Chelsea Station. Refer to Table 2-4 for a list of connections. Through much of this sector, the route is in a dedicated busway with minimal roadway crossings located alongside the existing MBTA commuter rail Newbury/Rockport line, which would enable faster and more reliable operation than in mixed traffic on existing roadways (e.g., Revere Beach Parkway/Route 16). Transitoriented development opportunities at the Chelsea Downtown and Everett Avenue station locations are rated high. Urban Ring Service. Urban Ring service would be available on three BRT routes: • Route 1 - Airport Blue Line Station to Kendall Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) Urban Ring Phase 2 RDEIR/DEIS Page 2-11 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Route 2 - Logan Airport to Sullivan Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) • Route 7 – Yawkey to Mystic Mall (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) Route and Running Way • Eastern Avenue in mixed traffic to Griffin Way in mixed traffic to Griffin Way Station • Busway in abandoned railroad bed (adjacent to Rockport commuter rail line) to Downtown Chelsea Station (commuter rail connection) • Busway in abandoned railroad bed continues to Mystic Mall Station The alignment total for this segment is 2.0 miles, of which 60 percent would be exclusive busway and 40 percent would be mixed traffic operation. Average travel speeds would be approximately 14 mph in each direction. Demographics. An estimated 28,200 people will live within a one-half mile walk of one of these four stations, and 10,900 people will work within one-half mile of a station by 2030, the project horizon planning year. Significantly, the Urban Ring Phase 2 is expected to serve large environmental justice (EJ) populations in this area, as more than three-fourths of year 2000 residents near these stations live within TAZs that meet regional Environmental Justice criteria. Outstanding Issues. The following is a summary of key environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. In addition, there is some uncertainty in this segment of the LPA alignment that merits special recognition. More detailed summary information is provided in Chapters 4 and 5.. Transportation Issues • The principal outstanding issue related to future risk and uncertainty in this sector of the corridor is right-of-way acquisition of the CSX-controlled abandoned rail corridor that extends from East Chelsea through Everett along the south side of the active MBTA-owned Newburyport/Rockport commuter rail line. Protecting the integrity of this abandoned rail corridor was identified in the MIS (2001) and DEIR (2004) as a high priority to facilitate its acquisition and conversion to transit use for the Urban Ring. Environmental Issues • Sites where hazardous materials have been identified are limited to 3 locations where underground storage tanks have been identified or are listed as unclassified sites. Economic Development • The three proposed stations in this sector have high potential to spur economic development and redevelopment. The alignment and stations are compatible with local planning goals for new transit-oriented development. Stations are within walking distance of high density residential neighborhoods. Urban Ring Phase 2 RDEIR/DEIS Page 2-12 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE 2.1.3 Sector 3: Everett Sector 3 of the LPA continues the busway along the south side of the Rockport commuter rail line, passes beneath the rail line in a new bus only underpass, then beneath the existing Route 99 underpass. The LPA alignment then turns north following adjacent to the Saugus Branch rail spur, which passes beneath Revere Beach Parkway and then west adjacent to the north side of the Parkway where it crosses the Malden River to reach the Wellington Orange Line station. See Figures 2-5 and 2-6 for Sector 3 alignment of the LPA. The alignment in this sector is provided entirely in exclusive busway. As a result travel times and reliability would be greatly improved over the future No-Build and Baseline alternatives which travel on the congested Revere Beach Parkway. Travel time for the one mile between Everett Station in Everett and Mystic Mall Station in Chelsea would be approximately 2 minutes. This is much faster than any existing bus route in the area. Stations. The LPA includes one station in this sector that would be located at: • Everett This station would provide connections with five MBTA bus routes. Refer to Table 2-5 for list of connections. Through much of this sector, the BRT busway would be located alongside the existing MBTA commuter rail Newbury/Rockport line, which would enable faster and more reliable operation. Urban Ring Service Urban Ring service would be available on two BRT routes: • Route 1 – Airport Blue Line Station to Kendall Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) • Route 2 - Logan Airport to Sullivan Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) Route and Running Way • Busway in abandoned railroad bed (adjacent to the commuter rail line) continues to the west of Second Street • Busway enters tunnel (south of Sweetser Circle and east of Everett Station) and crosses beneath railroad tracks and Route 99 • Busway passes beneath Revere Beach Parkway via Saugus Branch rail underpass to Everett Station • Busway runs along northern side of Revere Beach Parkway • Busway crosses Malden River on a new bridge north of the Revere Beach Parkway Bridge • Corporation Way in mixed traffic to Wellington Station (Orange Line and bus connections) The alignment total for this segment is 1.0 mile, of which 100 percent would be exclusive busway. Average travel speeds would be approximately 28 mph in each direction. Demographics. An estimated 5,400 people will live within a one-half mile walk of one of these four stations, and 4,300 people will work within one-half mile of a station by 2030, the project horizon planning year. Significantly, the Urban Ring Phase 2 is expected to serve large environmental justice (EJ) populations in this area, as more than 4,500 residents near these stations live in TAZs that meet regional Environmental Criteria. Outstanding Issues. The following is a summary of key environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and Urban Ring Phase 2 RDEIR/DEIS Page 2-13 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE design stages of the planning and environmental review process. In addition, there is some uncertainty in this segment of the LPA alignment that merits special recognition. More detailed summary information is provided in Chapters 4 and 5. Transportation Issues • The proposed busway bridge across the Malden River would require review and permitting related to waterways access and environmental impacts. The U.S. Coast Guard would need to review the proposal to determine whether a moveable span would be required at this location to enable adequate waterways access. If the U.S. Coast Guard approved a fixed span in this location, the capital, operating and maintenance costs would be lower, which would improve the cost effectiveness of the project. A fixed span may have the further advantage of potential cost savings on construction of the busway bridge, because the existing six-lane moveable span that carries the Revere Beach Parkway in this corridor is in need of replacement. The owner of the bridge, the Department of Conservation and Recreation, has indicated that it may be necessary to construct a temporary bridge for maintenance of traffic. If design and timing issues could be addressed, converting the temporary bridge to later busway use could reduce the environmental impacts and costs of a completely new busway bridge over the Malden River. Environmental Issues • The main environmental issue within this sector is potential wetland and Chapter 91 impacts on the Malden River, and impacts to associated plant and animal species and habitats. The proposed busway may impact wetlands and water resources associated with the Malden River. Bordering vegetated wetlands, characterized as a palustrine emergent wetland and dominated by common reed and broad-leaved cattail, are located along both sides of the Revere Beach Parkway east of the proposed Malden River crossing. Additionally, the Malden River itself may be impacted by the construction of a new busway that would also trigger Chapter 91 licensing. Impacts may include filling or altering wetland resource areas. • Within this sector, open sites with identified hazardous materials include Monsanto Chemical located on Mystic View Road (RTN 3-0313), which is a Tier II site where a release of an unknown chemical occurred in a lagoon, and an unidentified site also located at 2401 Revere Beach Parkway (RTN 3-26369), which is an Unclassified Waste Site. In addition, this sector has four locations where underground storage tanks have been identified or are listed as unclassified sites. • Moderate to high archaeological sensitivity on shorelines and in river for the new Malden River busway bridge. Moderate sensitivity for the busway route in cross-country section through rail yard. • Parkland along the northern roadway edge of Revere Beach Parkway between Sweetser Circle and Santilli Circle in Everett may be affected. While the segment of land affected by the new busway does not contain any passive or active recreational areas, it is owned by DCR and thus would trigger a Programmatic Section 4(f) Evaluation and Article 97 conversion. Although the area is not actively used for recreation, it is an open space that is part of the DCR parkway system. • Revere Beach Parkway is a general use parkway, so no adverse environmental consequences associated with bus use within the existing roadway is anticipated. Urban Ring Phase 2 RDEIR/DEIS Page 2-14 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Economic Development • The proposed Everett Station supports planned development projects in the area including Rivers Edge. The project could help to enhance transit-oriented and smart growth development in the area. 2.1.4 Sector 4: Wellington/Somerville/Charlestown Sector 4 of the LPA alignment passes through Wellington Circle and uses the Fellsway to access Assembly Square and then existing streets to reach Sullivan Square, and then through the Inner Belt district in Somerville, from which it would use a new busway viaduct to pass over the Fitchburg Line commuter rail tracks to reach New Lechmere Station in East Cambridge. See Figures 2-6 and 2-7 for Sector 4 alignment of the LPA. A combination of busways and bus lanes would be provided through most of this sector, including over the Malden River and through Inner Belt Road, and connecting Inner Belt Road to New Lechmere. The project would also take advantage of the planned improvements at Wellington Circle. These features would improve travel time and reliability over the Baseline alignment, which would use congested local roadways. The project would connect with the Orange Line at two locations in this sector (three if the proposed Orange Line station at Assembly Square were implemented and the BRT routed to connect with it) and with the commuter rail. These connections would improve service and options for riders. Stations. The LPA includes four stations in this sector that would be located at: • Wellington (Orange Line, major bus hub connections); • Assembly Square (potential future Orange Line connection); • Sullivan Square (Orange Line, proposed new commuter rail, major bus hub connections); and • Inner Belt. These stations would provide connections with 19 MBTA bus routes and two connections with existing MBTA Orange Line stations at Wellington Station and Sullivan Square (there is also a proposal for a new Orange Line station at Assembly Square). Refer to Table 2-6 for a list of connections. Future transitoriented development opportunities are rated highly at all four station locations. Urban Ring Service. Urban Ring service would be available on three BRT routes: • Route 1 – Airport Blue Line Station to Kendall Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) • Route 2 - Logan Airport to Sullivan Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) • Route 5 – Sullivan Square to Ruggles Station (headways = 7 minutes peak periods, 12 minutes midday and Saturday, and 15 minutes nighttime, Sundays and holiday) Route and Running Way • • • • Revere Beach Parkway through Wellington Circle in mixed traffic Route 28 in mixed traffic to Middlesex Avenue Middlesex Avenue to Assembly Square Station Assembly Square Station to Mystic Avenue/Broadway in mixed traffic Urban Ring Phase 2 RDEIR/DEIS Page 2-15 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Mystic Avenue in mixed traffic to Sullivan Square Station (Orange Line, proposed new commuter rail, major bus hub connections) • Cambridge Street/Washington Street in mixed traffic and bus lanes to Inner Belt Road • Inner Belt Road in bus lanes to Inner Belt Station • Inner Belt Road in bus lanes to new busway viaduct over railroad tracks to New Lechmere Station (Green Line connection) The alignment for this segment measures 3.0 miles, of which 20 percent would be separated running way. Average travel speeds would be approximately 12 mph in each direction. Demographics. An estimated 25,700 people will live within a one-half mile walk of one of these four stations, and 33,400 people will work within one-half mile of a station by 2030, the project horizon planning year. Approximately half of all residents living within this radius of future stations live in TAZs that meet regional Environmental Justice criteria. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. More detailed summary information is provided in Chapters 4 and 5. Transportation Issues • Wellington Circle, at the intersection of Revere Beach Parkway/Route 16 and the Fellsway/Route 28, currently has heavy traffic congestion. The Boston Region MPO’s Regional Transportation Plan includes a major improvement project for Revere Beach Parkway/Route 16 that would entail grade-separation of this intersection. This is important for optimizing travel time on this segment of the Urban Ring alignment. • EOT is coordinating with the City of Somerville to review the future street network at Assembly Square in East Somerville. There are challenges to providing bus lanes near the proposed center of the Assembly Square district. • EOT is coordinating with the City of Boston and the MBTA on accommodating bus lanes into and out of Sullivan Square and bus circulation at the station through an ongoing City of Boston planning and design effort for Sullivan Square. This effort is intended to improve travel time and reliability for existing MBTA bus routes, as well as potential Urban Ring Phase 2 bus connections, whether via the current LPA or an adjusted alignment via the Route 99 corridor (as in Alternative 4A, described in Chapter 3). • EOT will coordinate with on the future street network at the west end of the North Point development in East Cambridge to ensure that it can accommodate a connection to the planned Urban Ring busway between Inner Belt and North Point. Environmental Issues • The main environmental issue within this sector is the reconstruction of the bridge over the Malden River and potential wetland and Chapter 91 impacts, and impacts to associated plant and animal species and habitats. As in Sector 3, the proposed busway crossing at the Malden River may impact the wetlands and water resources associated with the river. Proposed work within the Malden River would trigger Chapter 91 licensing. • Within this Sector, open sites with identified hazardous materials include the MBTA Water Street Car House located on Water Street (RTN 3-18502), which is a Tier II site where naphthalene and Urban Ring Phase 2 RDEIR/DEIS Page 2-16 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE 2-methylnaphthalene have been released, the East Cambridge Service Yard located on East Street (RTN 3-12467), which is a Tier ID site where a release of TPH occurred the property located at 30 Allen Street identified as a US Brownfield site and B&M Yard 21 located at Foley Street and Tenney Court (RTN 3-4082), which is a Tier II site relative to a release of an unknown chemical. Economic Development • The project is consistent with and enhances the proposed development at Assembly Square, which is being developed as a mixed-use transit-oriented development. Urban Ring service would provide enhanced transit connectivity and capacity for Assembly Square. • The project would bring bus rapid transit to Somerville’s Inner Belt district, which currently does not have transit service. It would provide fast and direct connections between Inner Belt and many radial transit services, in particular the Orange Line and commuter rail at Sullivan Square Station; the Green Line at New Lechmere Station; and the Red Line at Kendall/MIT Station. This would enhance transit-oriented and smart growth development opportunities in this area. • The project would increase the transit connectivity and capacity for Sullivan Square by providing a new commuter rail stop on the Newburyport/Rockport line and the Haverhill line, and by providing better connectivity with other parts of the Urban Ring corridor. This would enhance transit-oriented and smart growth development opportunities in this area. Based on the transportation and environmental issues identified by the cities of Everett, Somerville and Boston, the LPA alignment between Everett and Sullivan Square is under review. 2.1.5 Sector 5: East Cambridge Sector 5 of the LPA alignment extends between New Lechmere and Kendall Square. Bus lanes on First Street and a short busway connection between Third Street and Main Street near Kendall Square would produce faster travel times and greater reliability than is possible with the existing transit network. Connections to the Red and Green Lines would improve service and allow riders to travel west to reach destinations such as Boston University and the Longwood Medical and Academic Area in Boston rather than traveling first into the central Boston subway system before traveling west. See Figures 2-7 and 2-8 for Sector 5 alignment of the LPA. Stations. The LPA includes five stations in this sector that would be located at: • New Lechmere (Green Line, major bus hub connections); • First Street Galleria; • Binney Street; • Fulkerson Street; and • Kendall/MIT (Red Line, major bus hub connections). These stations would provide connections with seven MBTA bus routes and connections with the Green Line at Lechmere and the Red Line at Kendall Square. Refer to Table 2-7 for a listing of connections. Future transit-oriented development opportunities are rated highly at the station locations. Urban Ring Service. Urban Ring service would be available on two BRT routes, which overlap between Kendall Square and Lechmere: Urban Ring Phase 2 RDEIR/DEIS Page 2-17 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Route 1 – Airport Blue Line Station to Kendall Square (headways = 10 minutes peak periods, 15 minutes midday and Saturday, and 20 minutes nighttime, Sunday and holiday) • Route 5 – Sullivan Square to Ruggles Station via LMA (headways = 7 minutes peak periods, 12 minutes midday and Saturday, and 15 minutes nighttime, Sundays and holiday) Route and Running Way • First Street in bus lanes to Binney Street in mixed traffic to Binney Street Station • To Kendall/MIT Station (Red Line connection) via one of two routes: o Binney Street in mixed traffic to Fulkerson Street Station to Main Street to terminate at o Kendall/MIT Station OR Third Street in mixed traffic to busway connection to Main Street to Kendall/MIT Station The alignment total for this segment is 2 miles; of which 28 percent would be separated running way and 72 percent would be mixed traffic operation. Average travel speeds would be approximately 13 mph in each direction. Demographics. An estimated 25,500 people would live within a one-half mile walk of one of these four stations, and 54,000 people would work within one-half mile of a station by 2030, the project horizon planning year. Approximately 14,100 residents live within this radius of future stations live in TAZs that meet regional Environmental Justice criteria, based on 2000 population data. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. More detailed summary information is provided in Chapters 4 and 5. Transportation Issues • The main transportation issue in Sector 5 is the proposed bus lanes on First Street near Cambridgeside Galleria. These bus lanes are important for speed and reliability of service between New Lechmere and Kendall Square. First Street currently has a four-lane cross-section, with two general-purpose lanes in each direction. Traffic volumes and congestion are relatively low, and should not present a problem for converting one lane in each direction to bus lane. However, there is currently illegal parking in these curb lanes, which would need to be addressed through signage and enforcement. Keeping bus lanes clear of parked vehicles and loading and unloading will be a priority of the Urban Ring project. Bus lanes and busways along the project corridor would be consistently signed, striped and demarcated to project an overall bus operation to the motoring public. Consistent enforcement of illegally parked vehicles would be a key element of this operation. EOT and MBTA will coordinate these issues as the project progresses. Environmental Issues • The main environmental issue is the proposed short busway section at Galaxy Park near Kendall Square. This connection is needed to directly connect Third Street and Main Street, and to provide faster, more direct connections to and from Kendall/MIT Station. Preliminary designs have shown that this element can be implemented without significant impact on the park. However, the alignment would require taking a small amount of open space that was purchased or improved by public money which would create parkland impacts. Alternative routings would be available on existing roadways if necessary. Urban Ring Phase 2 RDEIR/DEIS Page 2-18 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Economic Development Issues • The project would increase the transit connectivity and capacity for New Lechmere Station and the proposed North Point development by providing better connectivity with the Red Line at Kendall/MIT and other parts of the Urban Ring corridor. This would enhance transit-oriented and smart growth development opportunities in this area. • The three new stations (in addition to Kendall and New Lechmere) would increase transit access for riders. These stations are consistent with the type of transit-oriented development that is being proposed and constructed in East Cambridge. 2.1.6 Sector 6: Cambridgeport/Charles River Crossing Sector 6 of the LPA alignment passes through the campus of the Massachusetts Institute of Technology (MIT) and the Cambridgeport neighborhood of Cambridge; it then crosses the Charles River to connect with Boston University and the Mountfort Street corridor in the Cottage Farm neighborhood of Brookline. See Figure 2-8 for Sector 6 alignment of the LPA. This sector includes a combination of bus lanes on Albany Street and a busway on the Grand Junction Railroad corridor (west) that includes a busway across a reconstructed Grand Junction Railroad bridge. The busway in this sector connects with a new station at Commonwealth Avenue/Boston University. The LPA alignment provides significant travel time benefits in that it provides a direct alignment between Kendall Square and Boston University. The Baseline alignment would require using local streets in Cambridgeport and traveling through the BU rotary which is often congested and susceptible to Red Sox game traffic. This sector also provides for a new Green Line station at Commonwealth Avenue. Stations. The LPA includes three stations in this sector that would be located at: • MIT/Massachusetts Avenue; • Cambridgeport; and • Boston University (Green Line B Branch connection ). These stations would provide connections with three MBTA bus routes. Refer to Table 2-8 for a listing of connections. Future transit-oriented development opportunities are rated highly at the station locations. Urban Ring Service. Urban Ring service would be available on two BRT routes: • Route 5 – Ruggles Station to Sullivan Square via LMA (headways = 7 minutes peak periods, 12 minutes midday and Saturday, and 15 minutes nighttime, Sunday and holiday) • Route 6 – JFK/UMass to Harvard Square via LMA (headways = 7 minutes peak periods, 12 minutes midday and Saturday, and 15 minutes nighttime, Sunday and holiday) BRT 5 would serve the entire length of Sector 6, from Kendall Square through the Charles River crossing. BRT 6 would serve the Boston University – Fenway segment only. Route and Running Way • From Kendall Square Station along Main Street in mixed traffic • Albany Street in combination of bus lanes and mixed traffic (bus lanes split between eastbound • and westbound to provide dedicated bus lane approaches MIT/Massachusetts Avenue Station Albany Street in combination of bus lanes and mixed traffic to Erie Street Urban Ring Phase 2 RDEIR/DEIS to intersections) to Page 2-19 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • • • • • • • Busway connection to Cambridgeport Station near Fort Washington Park Busway in Grand Junction Railroad alignment to Charles River Busway on Grand Junction Railroad Bridge across Charles River Busway beneath BU Bridge and beneath proposed future park space on existing Boston University Academy site University Road – Southbound in bus lane to Boston University Station – Northbound in mixed traffic Carlton Street Bridge over Mass Turnpike – Boston University Station to northbound in bus lane – Southbound in mixed traffic to bus-only connection Mountfort Street in bus lanes to Beacon Street (mixed traffic maintained on Mountfort Street) The alignment total for this segment is 2 miles, of which 69 percent would be separate running way and 31 percent would be mixed traffic. Average travel speeds would be approximately 12 mph in each direction. Demographics. An estimated 34,500 people would live within a one-half mile walk of one of these four stations, and 31,200 people would work within one-half mile of a station by 2030, the project horizon planning year. Significantly, more than three-fourths of residents near these stations live in TAZs that meet regional Environmental Justice criteria. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. In addition, there is some uncertainty in this segment of the LPA alignment that merits special recognition. More detailed summary information is provided in Chapters 4 and 5. Transportation Issues • Two-way BRT travel is proposed along Albany Street in alternating bus lanes on one side between Fort Washington Park and Main Street. The proposed bus lanes are at locations that would provide the best advantages for BRT travel along Albany Street, including queue-jump lanes in each direction at the approach to Massachusetts Avenue. The bus lane locations have been coordinated with the City of Cambridge. On the west end of Albany Street BRT buses would enter a two-way busway adjacent to Fort Washington Park (see next bullet). An interim routing via an Albany Street (eastbound) – Vassar Street (westbound) one-way pair may be necessary, depending upon the timing of busway construction. The interim condition would be coordinated between EOT, the City of Cambridge, and MIT. • Busway connection and station location adjacent to Fort Washington Park. The project alignment is currently proposed to connect from Albany Street to the Grand Junction Railroad alignment. There is currently an empty, MIT-owned parcel in this location bifurcated by an abandoned industrial rail right-of-way now owned by the City of Cambridge. EOT has coordinated with MIT and the City of Cambridge to develop a busway alignment and station location that serves the needs of the Urban Ring project; that serves the pedestrian, bicycle, and transit access needs of students and neighborhood residents; and that is compatible with the character of Ft. Washington Park and amenable to MIT parcel development needs. EOT will continue to coordinate with MIT and the City of Cambridge on the design of a busway connection in this area, in the context of other development plans. • Busway in the Grand Junction Railroad right-of-way. The LPA proposes a two-way busway connecting across the existing Grand Junction Railroad track in the vicinity of Fort Washington Park (at an existing pedestrian grade crossing). The two-way busway (on the southeast side of the Grand Junction Railroad single track) would connect under Memorial Drive, across the Charles River on a reconfigured and rebuilt railroad bridge, and over Storrow Drive. The busway Urban Ring Phase 2 RDEIR/DEIS Page 2-20 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE operation adjacent to the Grand Junction Railroad track and the reconstruction of the Grand Junction Railroad Bridge would require coordination with CSX Transportation, which owns the right-of-way. The Commonwealth of Massachusetts recently reached agreement with CSX on purchase of various CSX properties, including the Grand Junction Railroad, which is expected to facilitate coordination on reconfiguration and use of these facilities for the proposed Urban Ring. On an interim basis during design and construction of the reconfigured Grand Junction Railroad Bridge over the Charles River, Urban Ring buses may need to cross the Charles River in mixed traffic on the existing Boston University Bridge, as the existing MBTA CT2 and 47 buses do today. • Boston University Academy tunnel “Y” connection. The LPA alignment would connect from the Grand Junction Railroad alignment through a new tunnel beneath the Boston University Bridge and then beneath a proposed park space on the site currently occupied by the Boston University Academy, a private high school owned and operated by Boston University. As part of its campus master planning process, Boston University has indicated an intention to relocate BU Academy and pursue the creation of a publicly-accessible park space, with connections to the Charles River Esplanade, on that site. This would facilitate creation of the proposed LPA connection. The preliminary concept for the “Y” connection shows that this alignment appears to be feasible. Preliminary engineering will be conducted in a next phase of the Urban Ring project. This portion of the proposed LPA alignment can be developed separately from the Grand Junction Railroad alignment described above. Until and unless Boston University and other key stakeholders (including the Massachusetts Turnpike Authority, MassHighway, Department of Conservation and Recreation, the City of Boston, and others) are able to effect the relocation of BU Academy and the provision of access through the site, the Urban Ring alignment could connect to the Mountfort Street corridor via a viaduct connection from the Grand Junction Railroad, over the Mass Turnpike, to Commonwealth Avenue immediately west of the BU Bridge. • Heavy traffic volumes and congestion make use of the BU Bridge undesirable for Urban Ring access. Congestion would make travel times on the BU Bridge slower and less reliable than a connection via a reconfigured Grand Junction Railroad Bridge. • On the Boston side of the Charles River, the proposed LPA alignment would connect to the Mountfort Street corridor via the Carlton Street Bridge over the Mass Turnpike. The Urban Ring would be able to make use of a northbound bus lane on the Carlton Street Bridge if Cambridgebound traffic were able to continue westbound on Mountfort Street directly to the BU Bridge. This would remove enough traffic on the Carlton Street Bridge that a lane would be available for exclusive bus use. The additional traffic on Mountfort Street could be accommodated with a relatively minor reconfiguration of Mountfort Street within its existing footprint. This would also enable pedestrian and bicycle improvements to the BU Bridge intersection at Commonwealth Avenue, and to the Mountfort Street/Carlton Street intersection. Potential roadway reconfiguration and traffic circulation changes should be explored further in conjunction with the Massachusetts Turnpike, Department of Conservation and Recreation, City of Boston, Town of Brookline, Boston University, and other appropriate parties. Environmental Issues • The Urban Ring’s crossing over the Charles River may impact wetlands and other habitats associated with the river, including the river itself. Impacts may include filling or altering wetland or aquatic habitats. The proposed crossing may impact water resource areas associated with the river, including the river itself. • Within this Sector, open sites with identified hazardous materials include an unidentified site located at 22 Massachusetts Avenue (RTN 3-25323), which is a Tier II site where lead, 1,3,5trimethylbenzene, and naphthalene have been identified. In addition, 2 locations where Urban Ring Phase 2 RDEIR/DEIS Page 2-21 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE underground storage tanks have been identified or are listed as unclassified sites have been identified. • Moderate archaeological sensitivity in cross-country section from Albany Street across Charles River to Commonwealth Avenue/BU Station. Moderate to high sensitivity along cross-country route (National Register-listed Olmsted Park System). • The route passes Fort Washington on the adjacent railroad right-of-way and/or roadways; no “use” or conversion of this historical parkland would occur. The Memorial Drive overpass would be modified to accommodate a busway. As this is part of the DCR parkway system, a Section 4(f) evaluation would be triggered. Modifications to the Grand Junction Railroad Bridge could also trigger a Section 4(f) evaluation because the change to the private bridge could potentially affect the watershed of the publicly-owned Charles River. The recent agreement between the Commonwealth of Massachusetts and CSX regarding this and other rail properties could facilitate development of effective mitigation measures. The proposed Urban Ring modifications to the Grand Junction Bridge would include a pedestrian path connecting the existing and planned path networks on the north and south sides of the River. This path connection across the Charles River is a component of the Charles River Basin Master Plan developed by DCR. Economic Development Issues • The project would increase the transit connectivity and capacity for Boston University and the central BU Bridge area of the campus. This would enhance transit-oriented and smart growth development opportunities in this area, including the potential for decking over the MTA air rights parcels in the immediate vicinity. • The new stations at Mass Ave/MIT would increase transit access and connectivity for trips to this area, especially to and from the Red Line at Kendall Square. This would enhance transit-oriented and smart growth development opportunities in this area. 2.1.7 Sector 7: Allston/Harvard Square Cambridge Sector 7 comprises the Boston University West Campus area, the Allston Landing railyards, the North Allston neighborhood, and Harvard Square in Cambridge (to enable connection to the Red Line rapid transit). Although the Urban Ring project has been in planning for many years, the potential BRT connection to Allston is a new proposal, dating from the 2004 Certificate issued on the Draft Environmental Impact Report (DEIR), as discussed in Chapter 1, Purpose and Need. As a result, there has been no previous opportunity for formal public comment on Urban Ring proposals in Allston, as there has been in all other areas of the corridor. See Figures 2-7 and 2-8 for Sector 7 alignment of the LPA. In addition, there are major challenges with making fast, direct BRT connections in this segment of the corridor, due in large part to the barriers presented by the Massachusetts Turnpike and the Beacon Park Yards railroad yard. There is significant uncertainty associated with future rail operations in Beacon Park Yards and ongoing negotiations with CSX Transportation (CSX) over the future of Beacon Park Yards. In addition, the Massachusetts Turnpike viaduct adjacent to the Beacon Park Yards is in need of significant repair and rehabilitation in coming years. In recognition of these issues, the project recommendations include a range of alternatives for making connections to Allston. The following are the primary options for making the connection from the BU Bridge area to the Cambridge Street corridor in Allston: A. Busway beneath Mass Turnpike viaduct and through Beacon Park Yards at the railroad level. Optional routing would be evaluated in the engineering phase of the project. Options may include Urban Ring Phase 2 RDEIR/DEIS Page 2-22 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE connections between existing Turnpike viaduct columns in addition to busway to between the Turnpike viaduct and Soldiers Field Road. B. BRT operation on Commonwealth Avenue in mixed traffic to Malvern Street, where buses would travel over the rail yard via a viaduct. Preliminary evaluation shows that business land takings may be required to construct the viaduct. C. Commonwealth Avenue in mixed traffic to Brighton Avenue in mixed traffic to Cambridge Street in mixed traffic. EOT is also coordinating with the City of Boston and Harvard University, which are undertaking master planning efforts in the North Allston neighborhood, north of Cambridge Street. This coordination is intended to facilitate further examination of community and stakeholder priorities in identifying a route north of Cambridge Street that preserves the operating characteristics of BRT while equitably balancing the service needs of the neighborhood and Harvard University. As a result of these ongoing planning efforts EOT has identified the following potential Urban Ring Phase 2 routes north of Cambridge Street: A. Busway in abandoned railroad bed between Cambridge Street and Mass Turnpike to North Harvard Street Station, busway continues underneath Cambridge Street to bus lanes in proposed new Stadium Way to Barry’s Corner Station B. Busway in abandoned railroad bed between Cambridge Street and Mass Turnpike to North Harvard Street Station, in mixed traffic with limited bus lanes on North Harvard Street to Barry’s Corner Station C. Cambridge Street Station to Lincoln Street in mixed traffic to Holton Street to potential bus lanes in potential new roadway to Brighton Mills Station, mixed traffic on Western Avenue to Barry’s Corner Station The different options in these two segments (1) BU Bridge – Cambridge Street corridor and (2) Cambridge Street corridor – Barry’s Corner are independent of each, and any option for each could be combined with any option for the other. For the sake of simplicity, they are described here as being combined (southern option A with northern option A, etc.) Urban Ring service in Sector 7 would be available on one BRT route that would serve each of the potential alternative alignments: • Route 6 – JFK/UMass to Harvard Square via LMA (headways = 7 minutes peak periods, 12 minutes midday and Saturday, and 15 minutes nighttime, Sunday and holiday) Any of the potential alternative alignments would provide more direct connections between the LMA and BU and Allston and Harvard Square than existing public services. New connections would be provided to the Red Line at Harvard Square, and potentially to a new commuter rail station on the Framingham Worcester line. The following is a summary of the key characteristics and issues associated with the three alternative alignments described above. Option A – Railyard Level Busway Stations. This option includes four stations in this sector that would be located at: • West Station - potential future commuter rail stop locations are being evaluated as part of the North Allston commuter rail study for EOT; Urban Ring Phase 2 RDEIR/DEIS Page 2-23 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • North Harvard Street – proposed for the vicinity of the intersection of North Harvard Street and Cambridge Street; • Western Avenue – proposed for the vicinity of the planned Stadium Way roadway at the intersection of Western Avenue and Stadium Way; and • Harvard Square. These stations would provide connections with 14 MBTA bus routes, as well as one connection to the MBTA Red Line (at Harvard Square) and commuter rail at Allston West Station. The locations of the station would differ slightly depending on the option. Refer to Table 2-9 for a listing of connections. Future transit-oriented development opportunities are rated highly at the station locations. Route and Running Way • Beginning at the “Y” connection, south of the Grand Junction Railroad Bridge a two-way busway: • • • • • • would extend westerly between Mass Turnpike and Soldier’s Field Road and then beneath the Mass Turnpike viaduct. The busway would follow the existing railroad alignment south of the Mass Turnpike in Beacon Park Yard. Busway along perimeter of railyard with connection to West Station (potential future commuter rail connection) Busway under Mass Turnpike viaduct and along railroad bed between Cambridge Street and Mass Turnpike to North Harvard Street Station Busway connection continues along railroad bed, underneath Cambridge Street to planned new Stadium Way Stadium Way in bus lanes to Western Avenue Station/Barry’s Corner Station North Harvard Street in bus lanes to Anderson Memorial Bridge over Charles River JFK Street to Eliot Street in mixed traffic. At Eliot Street, the northbound continues to Bennett Street in mixed traffic and uses the existing Harvard Square Bus tunnel at Mount Auburn Street and continues to an underground station at Harvard Square (Red Line connections). The southbound route uses surface streets and Harvard Square Surface Station. The southbound follows Massachusetts Avenue to Brattle Street in mixed traffic then continues to Eliot Street and JFK Street in mixed traffic. The alignment is 3 miles, of which 82 percent would be busway/bus lane and 12 percent would be mixed traffic operation. The mixed traffic portion is primarily between the Charles River and Harvard Square on JFK Blvd. Average travel speeds would be approximately 15 mph in each direction. Demographics. An estimated 42,500 people live within a one-half mile walk of one of the stations of which most live in TAZs that meet regional Environmental Justice criteria, and 39,800 people will work within one-half mile of a station. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues with this option. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. In addition, there is some uncertainty in this segment of the LPA alignment that merits special recognition. More detailed summary information is provided in Chapters 4 and 5. • Coordination would be required with CSX and Harvard University (owner of the property underlying Beacon Park Yards) to obtain operating permission and right-of-way to operate in the Beacon Park Yard. In addition to operating permission and right-of-way, this alignment may require the relocation of some CSX activities within Beacon Park Yard depending upon the route of the Busway Viaduct. The connection between the BU Bridge area, beneath the Mass Turnpike viaduct, into Beacon Park Yards would require crossing an active railroad track that Urban Ring Phase 2 RDEIR/DEIS Page 2-24 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE accommodates train operations and provides access to the “teardrop parcel.” There are a number of active railroad operations at Beacon Park Yard including the Grand Junction Railroad and access to the teardrop parcel (including municipal solid waste and locomotive fueling and servicing) that may preclude bus operations across this track. Therefore, this alignment may require that the railroad uses in the teardrop parcel be relocated. • Coordination and negotiation would be required with BU on impacts to its lands and campus. Transportation Issues • Coordination with MassPike Authority would be required for the busway beneath the Mass Turnpike viaduct. Coordination would include right–of-way issues, maintenance and cost. • Coordination with MBTA would be required for planning, construction and operation of a new commuter station. • Coordination will continue with Boston University and City of Boston, Department of Conservation and Recreation. Environmental Issues. The following are key environmental issues: • There are likely to be hazardous materials that would need to be removed in the Allston Railyard. • The Charles River Reservation and Allston neighborhood would experience noise and vibration impacts during construction as well as bus traffic when in operation. • Approximately 0.59 acres of the Charles River Reservation along Soldier’s Field Road would be affected. Although no walking paths or recreational areas are located in this section (in fact, this area is not publicly accessible), the property is DCR-owned and would require a Section 4(f) evaluation and an Article 97 approval. Economic Development Issues • Coordination with Harvard University would be required on the planning and development of their growing Allston campus, including accommodation of busways and bus lanes on existing and proposed new roadways. The EOT is also coordinating with the City of Boston’s Community-Wide Plan for Allston. Optional station locations including Barry’s Corner and Brighton Mills (via Holton Street) are being considered as they have been identified as important/development centers. Urban Ring routing to the stations is being evaluated. • Coordination with Boston University would be required for future planning efforts in the campus area to reflect both the Boston University’s Master Plan as well as the developments that have occurred to date. Boston University has finalized a Master Plan, complete with a TAPA with a City of Boston. Option B – Commonwealth Avenue and Malvern Street Busway Viaduct This alignment would connect along Commonwealth Avenue in mixed traffic, and then make a busway viaduct connection over the Beacon Park Yards in the Malvern Street corridor. Stations. The LPA includes stations in this sector at the following likely locations (pending further examination of potential viaduct locations over Beacon Park Yards): Urban Ring Phase 2 RDEIR/DEIS Page 2-25 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Packards Corner (Malvern Street); • West Station – potential future commuter rail stop locations are being evaluated as part of the North Allston commuter rail study for EOT; • North Harvard Street – proposed for the vicinity of the intersection of North Harvard Street and Cambridge Street; • Barry’s Corner – proposed for the vicinity of the intersection of North Harvard Street and Western Avenue; and • Harvard Square. These stations would provide connections with 14 MBTA bus routes, as well as one connection to the MBTA Red Line (at Harvard Square) and commuter rail at Allston West Station. The locations of the station would differ slightly depending on the option. Route and Running Way • For the viaduct option, buses would travel in mixed traffic on Commonwealth Avenue to • • • • • • Packard’s Corner then Malvern Street. Buses would travel over the rail yard via a viaduct. Preliminary evaluation shows that business/residential land takings on the Malvern Street side may be required to construct the viaduct. Because of these issues this option may not be feasible. Busway viaduct over Beacon Park Yards (at to-be-determined location), to busway connection under Mass Turnpike viaduct Busway connection along railroad bed between Cambridge Street and Mass Turnpike to North Harvard Street Station Cambridge Street in mixed traffic to North Harvard Street Station North Harvard Street in mixed traffic to Barry’s Corner Station North Harvard Street in bus lanes to Anderson Memorial Bridge over Charles River JFK Street in mixed traffic to Eliot Street in mixed traffic to Harvard Square Station (Red Line connections) The alignment is 2.8 miles, of which 50 percent would be busway/bus lane and 50 percent would be mixed traffic operation. The mixed traffic portions are along Commonwealth Avenue, Malvern Street and between the Charles River and Harvard Square on JFK Blvd. Demographics. An estimated 45,500 people live within a one-half mile walk of one of the stations of which most live in TAZs that meet regional Environmental Justice criteria, and 39,300 people will work within one-half mile of a station. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues with this option. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. In addition, there is some uncertainty in this segment of the LPA alignment that merits special recognition. More detailed summary information is provided in Chapters 4 and 5. • Coordination would be required with CSX and Harvard University (owner of the property underlying Beacon Park Yards) to obtain operating permission and right-of-way to operate in the Beacon Park Yard. In addition to operating permission and right-of-way, this alignment may require the relocation of some CSX activities within Beacon Park Yard depending upon the route of the Busway Viaduct. Urban Ring Phase 2 RDEIR/DEIS Page 2-26 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Additional coordination with Boston University and City of Boston will continue regarding optional alignment in connections through Beacon Park Yard. Transportation Issues • Coordination with MBTA would be required for planning, construction and operation of a new commuter station. • Coordination will continue with Boston University and City of Boston, Department of Conservation and Recreation. Environmental Issues • There are likely to be hazardous materials that would need to be removed in the Allston Railyard. • The Allston neighborhood would experience noise and vibration impacts during construction as well as bus traffic when in operation. • The BU Campus an in particular its Student Village area would experience noise and vibration impacts during construction as well as bus traffic when in operation. • Preliminary evaluation shows that business/residential land takings on the Malvern Street side may be required to construct the viaduct. Because of these issues this option may not be feasible. Economic Development Issues • Coordination with Harvard University would be required on the planning and development of their growing Allston campus, including accommodation of busways and bus lanes on existing and proposed new roadways. The EOT is also coordinating with the BRA’s community-based Allston planning program. Optional station locations including Barry’s Corner and Brighton Mills (via Holton Street) are being considered as they have been identified as important/development centers. Urban Ring routing to the stations is being evaluated. • Coordination with Boston University would be required for future planning efforts in the campus area to reflect the Boston University Master Plan. Boston University has finalized a Master Plan, complete with a TAPA for the City of Boston. Option C – Existing Surface Streets Stations. This option includes nine stations in this sector that would be located at: • Packard’s Corner; • Linden Street; • Brighton Avenue/Harvard Avenue; • Union Square; • Cambridge Street/Harvard Avenue (potential future commuter rail stop); • Franklin Street; • Brighton Mills; Urban Ring Phase 2 RDEIR/DEIS Page 2-27 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Barry’s Corner; and • Harvard Square. These stations would provide connections with 14 MBTA bus routes, as well as one connection to the MBTA Red Line (at Harvard Square) and commuter rail at Allston West Station.

An estimated 56,400 people live within a one-half mile walk of one of the stations of which most live in TAZs that meet regional Environmental Justice criteria, and 44,900 people will work within one-half mile of a station. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. More detailed summary information is provided in Chapters 4 and 5. Transportation Issues • Coordination with Harvard University would be required on accommodating busways and bus lanes on existing and proposed new roadways. • Coordination with MBTA would be required for planning, construction and operation of a new commuter station. • Coordination will continue with Boston University and City of Boston, Department of Conservation and Recreation. Environmental Issues. The following are key environmental issues: • The Allston neighborhood and BU Campus would experience noise and vibration impacts during construction as well as bus traffic when in operation. Urban Ring Phase 2 RDEIR/DEIS Page 2-28 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Economic Development Issues • Coordination with Harvard University would be required on the planning and development of their growing Allston campus, including accommodation of busways and bus lanes on existing and proposed new roadways.

Boston University has finalized a Master Plan, complete with a TAPA with a City of Boston. Summary EOT has been actively coordinating with the City of Boston and Harvard University regarding Urban Ring alignments, location of busways, bus lanes, station locations, commuter rail station locations, and planned Harvard University development. EOT has attended and presented at several of the North Allston public neighborhood meetings. Discussions continue of the issues surrounding the North Allston options. Other options may be identified/evaluated in addition to the options identified above. EOT is also overseeing a study focusing on the North Allston commuter rail issues. The goal of the North Allston process is to reach consensus on transportation issues by the time the final environmental documents are submitted to the state and FTA. 2.1.8 Sector 8: Boston/Fenway/Longwood Medical and Academic Area Sector 8 of the LPA alignment extends from Yawkey Station to Ruggles Station via Fenway Station at Park Drive and the Longwood Medical and Academic Area (LMA). The majority of the alignment would be in tunnel, with short segments of surface busway and bus lane. See Figures 2-8 and 2-9 for Sector 8 alignment of the LPA. The key transportation feature of Sector 8 is a new bus tunnel between the vicinity of the Landmark Center and Ruggles Station. Principal tunnel elements include the portals, the running tunnels, and the stations. The current BRT requirements were the controlling factor in determining tunnel cross sections. Typical cross sections have been developed, as far as practicable, to take into account Phase 3 rail requirements (see Chapter 3, Section 3.15.5). For example, a minimum horizontal radius of 700-ft has been assumed to allow for Phase 3 rail conversion. Further refinement to the BRT vehicle envelope in subsequent engineering studies may afford a reduction in the tunnel cross sectional area. There are a number of different tunneling techniques that can be used to construct the running tunnels. The primary ones under consideration are: cut and cover tunnel; sequential excavation method (SEM) mined tunnel; and tunnel boring machine (TBM) bored tunnel. With each of these techniques there is the possibility to construct a single tunnel carrying two lanes or two tunnels each carrying one lane. While each of these techniques has been considered, either exclusively or in combinations, in the development of the tunneled alignment alternatives, the initial assumption is that the running tunnels would be constructed using a TBM in a single bore configuration. Alternative construction methods and configurations (e.g. twin bored tunnels, cut and cover tunnels, or SEM mined tunnels) will be re-assessed during subsequent engineering studies and as more information on geology, hydrogeology, settlement and building response, electromagnetic field impacts, and noise and vibration becomes available. Urban Ring Phase 2 RDEIR/DEIS Page 2-29 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Systems required within the tunnel and associated structures to enable the safe operation of BRT services include tunnel ventilation, tunnel lighting, electrical and safety equipment, drainage, and vehicle recovery.4 The tunnel would allow buses to operate unimpeded, with much faster travel speeds than would otherwise be possible on the existing congested roadways (especially on the limited street network in the LMA). The tunnel does not preclude the use by other public and private shuttle buses, as long as they are dual mode fuel vehicles that can operate on electric power in tunnels. New bus lanes would also be provided between Yawkey and BU Bridge stations. As a result, almost the entire alignment in this sector would be in exclusive running way. These features would greatly improve travel times between the LMA, Yawkey and destinations to Roxbury and Dorchester. The new underground BRT stations between the intersection of Longwood Avenue and Avenue Louis Pasteur and Binney Street, and at the Fenway Station of Green Line D Branch could reduce the number of buses that need to circulate or lay over in this area, which could reduce conflicts and improve vehicular and pedestrian operations. New connections would be provided to Green and Orange Lines and commuter rail at Yawkey and Ruggles Stations. No BRT routes terminate at Tugo Circle in the LPA, therefore no buses would be required to layover at this station. Stations. The LPA includes four stations in this sector that would be located at: • Yawkey Station (Framingham/Worcester commuter rail connection); • Fenway Station/ Park Drive (Green Line D Branch); • LMA (underground station between the intersection of Longwood Avenue and Avenue Louis Pasteur and Binney Street); and • Ruggles Station (Orange Line, proposed improvements to Attleboro/Stoughton, Franklin, and Needham commuter rail, and major bus hub connections). These stations would provide connections with 11 MBTA bus routes and would connect with the Green Line D Branch at Fenway Station and with the Green Line E Branch via a short walk from either the LMA Station or Ruggles Station. Connections with the Orange Line would occur at Ruggles Station. Connections with the Framingham/Worcester Line would be made at Yawkey Station; and Providence Line and its existing and planned branches would occur at Ruggles Station. These stations would also be available for private shuttle stops. The number of private shuttle routes that have the potential to connect with the Urban Ring stations will change between now and the project completion. The Urban Ring project has the potential to reduce the number and route of some of the existing private shuttles. This will be evaluated by EOT and MBTA as the project progresses. Refer to Table 2-10 for a listing of connections. Future transit-oriented development opportunities are rated highly at the station locations. The locations of stations and headhouses have been generally located for the LPA alignment based on information collected as part of this RDEIR/DEIS. Precise locations of stations and headhouses will be determined by additional study that will be performed during a preliminary engineering phase of the study. The LPA alignment does not preclude additional station connections in the future if they are warranted by demand. One example would be consideration of a connection with the Green E Line. Urban Ring Service. Urban Ring service would be available on three BRT routes, which overlap within the LMA: 4 Tunnel systems and technology options are described in the Urban Ring Phase 2 Tunnel Alternatives Summary Report for the RDEIR/DEIS, November 2008. Urban Ring Phase 2 RDEIR/DEIS Page 2-30 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Route 5 – Ruggles Station to Sullivan Square via LMA (headways = 7 minutes peak periods, 12 minutes for midday and Saturday, and 15 20 minutes for Sunday, holiday) • Route 6 – JFK/UMass to Harvard Square via LMA, (headways = 7 minutes peak periods, 12 minutes for midday and Saturday, and 15 minutes for Sunday, holiday) • Route 7 - Yawkey Station to Mystic Mall (headways = 10 minutes peak periods, 15 minutes for midday and Saturday, and 20 minutes for Sunday, holiday) Route and Running Way • Enter bus tunnel via portal adjacent to Green Line D Branch portal near Landmark Center • • • • Bus tunnel beneath the Riverway to underground Fenway/Park Drive Station (Green Line D connection) Bus tunnel beneath Emerald Necklace to Longwood Avenue to LMA Station Bus tunnel beneath Longwood Avenue to Huntington Avenue to Ruggles Street Portal on north side of Ruggles Street to busway connection into Ruggles Station (Orange Line, commuter rail, and bus connections) The alignment between the Fenway/Park Drive Station and the intersection of Longwood Avenue and Brookline Avenue has not yet been determined. Options still under consideration include a tight turn under Brookline Avenue, a medium turn under the Windsor School, or a wide turn under Longwood Avenue and the Emerald Necklace (see Figures 2-8 and 2-9). The wide turn option, which extends the tunnel alignment to continue along Longwood Avenue prior to making the turn to the north to connect with the Landmark Center portal, may afford an opportunity to alleviate impact to the Windsor School. The alignment total for this segment is 2.0 miles; of which 20 percent would be separated running way and 80 percent would be tunnel. Average travel speeds would be approximately 17 to 18 mph depending on direction and time of day. Demographics. An estimated 48,300 people would live within a one-half mile walk of one of these four stations, and 67,200 people would work within one-half mile of a station by 2030, the project horizon planning year. More than three-fourths of residents near these stations live in TAZs that meet regional Environmental Justice criteria. It should be noted that the population and employment projections could be higher than the CTPS model provides since the model is constrained by a cap on regional growth. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. In addition, there is some uncertainty in this segment of the LPA alignment that merits special recognition. More detailed summary information is provided Chapters 4 and 5. • Tunnel alignment, construction and cost analysis is still underway. Preliminary analysis is reflected in this document. The complexity of the tunnel engineering and uncertainty surrounding geotechnical conditions in the LMA mean that final alignment and tunneling method (i.e. tunnel boring machine versus sequential excavation method) will need to be evaluated in the preliminary engineering and final environmental phases. However, the tunnel boring machine method appears at this time to generate fewer impacts to the surrounding area. • The impacts of the LPA in the LMA area would focus on tunnel and station construction. The level of impacts to private property owners would depend on the type of tunnel construction method used. The impacts due to tunnel construction would be temporary during the construction phase. Urban Ring Phase 2 RDEIR/DEIS Page 2-31 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Transportation Issues • The cost of the entire project is high and is expected to require funding in addition to federal and state funding sources. The timing for acquiring additional funding has not been determined. However, some sections of the LPA can be constructed in advance of other sections. The complexity of issues (engineering, design and construction) surrounding the proposed tunnel under the LMA may necessitate the tunnel section being deferred to a later date. The LMA’s transit needs, however, are immediate and growing. Therefore, EOT is developing recommendations for a potential interim surface alignment that would allow nearer term circumferential transit improvements. This alignment has not yet been finalized, but it is expected to entail some elements of bus lane on existing roadways in the LMA, and limited use of the Fenway segment of the Emerald Necklace Parkway system. Stakeholders have expressed concerns about impacts of these proposals, and EOT is continuing to work with stakeholders to develop an interim surface proposal that improves transit travel time and reliability while minimizing impacts. EOT is continuing to coordinate with the City of Boston and stakeholders regarding potential interim solutions in the LMA. • To the extent that tunnel construction requires cut-and-cover sections, the transportation access needs of the LMA must be considered. • The development of the Mass Turnpike Authority Parcel 7 will include the construction of a new Yawkey Station as well as new streets serving the development and the station. EOT has been coordinating with the MBTA, City of Boston, and the Parcel 7 developers regarding Urban Ring alignment and access. Environmental Issues • Construction of the proposed busway tunnel is not expected to impact the Muddy River, emergent wetlands associated with the river, or other wetlands along the alternative alignments. Protection of the adjacent wetlands in proximity to the west tunnel chamber may be necessary during construction. Following construction the tunnel and chamber will be completely underground in this area. • Within this Sector, open sites with identified hazardous materials include a Parking Lot at 1 Joslin Place (RTN 3-25456), which is a Tier II site where a release of 11.4 ppm of an unknown chemical occurred as well as a release of 0.24 inches of an unknown chemical, indicating floating product on the water table, and a Northeastern University facility located at 281-283 Ruggles Street (RTN 3-20978), which is a Tier II site resulting from a release of 1,1-dichloroethene, 1,2-dichloroethene, tetrachloroethene, trichloroethene, and 1,3-dichloro 1-propene. In addition, nine locations where underground storage tanks have been identified or are listed as unclassified sites have been identified. • Moderate to high historic and archaeological sensitivity along portions of the proposed tunnel route (recorded prehistoric site MHC#19-SU-81 and National Register-listed Olmsted Park System). • Construction of a busway tunnel portal at the Landmark Center may require moving a Boston Parks and Recreation building used for office and storage/maintenance facilities. Impacts in the park portion of the project area would be temporary and construction related, and existing conditions would be restored once the tunnel is completed. No significant permanent adverse impacts to parks and open spaces are anticipated from this project element, although this action may still trigger a Section 4(f) evaluation and Article 97 review due to the change in use of existing parkland. Coordination between EOT, the City of Boston, the Landmark Center, and MTA Parcel 7 will continue as the Urban Ring project advances. During the preliminary engineering Urban Ring Phase 2 RDEIR/DEIS Page 2-32 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE phase of the project, the specific location and operations of the portal would be evaluated. This would include ways to prohibit general traffic and pedestrians from entering the tunnel, avoiding conflicts between buses and general traffic/pedestrians, traffic control, grading, lighting, drainage etc. Based on the evaluation results, the exact portal location would be identified. • The LPA may result in temporary construction impacts at the Wentworth Institute fields near Ruggles Station, but there would be no permanent impacts or changes in use due to the proposed project. • During construction of the tunnel vibration levels could negatively impact highly sensitive academic, cultural, medical and research uses, Once the tunnel is completed little or no impact is expected from rubber tired BRT vehicles operating in the tunnel. Noise and vibration issues will require further research in the preliminary engineering phase. • Construction of a tunnel and station may impact future adjacent property uses and must be further evaluated in preliminary engineering. • Construction of the Urban Ring in the Fenway area assumes collaborative development and planning with Parcel 7 Turnpike Air Rights development, and 819 Beacon Street parcels. • Potential conflict with construction of the proposed Urban Ring portal and the multi-use path being proposed by the City of Boston linking Muddy River to the vicinity of the MTA Parcel 7 will be fully evaluated. Economic Development • Transportation access and capacity is constrained for the Longwood Medical and Academic Area. This major medical and educational cluster has Greater Boston’s highest density of jobs outside downtown. At the same time, it has a limited roadway network that carries high volumes of LMAbound traffic as well as general regional traffic. The Urban Ring would increase transit connectivity and capacity serving the LMA, and help to manage the impacts of rapid growth in this area. • The project would increase the transit connectivity and capacity for the Yawkey Station area, where a major transit-oriented development is proposed as well as the capacity in the Ruggles Station area through creation of an additional commuter rail platform. 2.1.9 Sector 9: Roxbury/ BU Medical Center Sector 9 of the LPA alignment extends from Ruggles Station to the Boston University Medical Center. It uses primary dedicated busway and bus lanes along City of Boston roadways. See Figure 2-9 for Sector 9 alignment of the LPA. The key transportation features in Sector 9 include a center median busway along Melnea Cass Boulevard and bus lanes on Albany Street through BU Medical Center. These elements would improve transit travel time and reliability in this congested corridor. The project would connect with the Silver Line BRT at Washington Street and Dudley Square stations. Stations. The LPA includes four stations that would be located at: • Washington Street (Silver Line connection); • Dudley Square (Silver Line and major bus hub connections); Urban Ring Phase 2 RDEIR/DEIS Page 2-33 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Crosstown Center; and • BU Medical Center. These stations would provide connections with 16 MBTA bus routes and connections with the Silver Line at Washington Street and Dudley Square. Refer to Table 2-11 for a listing of connections. Future transitoriented development opportunities are rated highly at the station locations. Urban Ring Service. Urban Ring service would be available on two BRT routes: • Route 6 – JFK/UMass to Harvard Square via LMA, (headways = 7 minutes peak periods, 12 minutes for midday and Saturday, and 15 minutes for Sunday, holiday) • Route 7 - Yawkey Station to Mystic Mall (headways = 10 minutes peak periods, 15 minutes for midday and Saturday, and 20 minutes for Sunday, holiday) Both routes would serve the Washington Street, Crosstown Center and BU Medical Center stations. Dudley Station would be served by Route 7. Connections to the Silver Line would be made at the Washington and Dudley Square stations. Route and Running Way • Service to Ruggles Station via busway to Melnea Cass Boulevard • Center median busway in Melnea Cass Boulevard to Washington Street Station (Silver Line connection) • Washington Street mixed traffic loop to Dudley Square Station (Silver Line connection) • Albany Street in mixed traffic to Crosstown Center Station • Albany Street in bus lanes to BU Medical Center Station The alignment total for this segment is 2.0 miles, of which 36 percent would be exclusive busway, 34 percent would be bus lane and 30 percent would be mixed traffic (along sections of Albany Street). Average travel speeds would be approximately 12 mph in each direction. Demographics. An estimated 26,900 people will live within a one-half mile walk of one of these four stations, and 22,900 people will work within one-half mile of a station by 2030, the project horizon planning year. Approximately 21,600 residents near these stations live in TAZs that meet regional Environmental Justice criteria. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. More detailed summary information is provided in Chapters 4 and 5. Transportation Issues • EOT will continue coordination with the City of Boston regarding the planned Melnea Cass corridor center busway alignment. This reconfiguration would enable streetscape improvements to the Melnea Cass corridor, and would facilitate the creation of a planned shared-use path, the South Bay Harbor Trail. • EOT will continue coordination with the City of Boston regarding the removal of on-street parking on Albany Street to provide bus lanes in both directions. Urban Ring Phase 2 RDEIR/DEIS Page 2-34 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • The project would provide a direct, frequent connection between the Boston University’s Charles River campus and the BU Medical Center. Environmental Issues • Within this Sector, open sites with identified hazardous materials include an unidentified site located at 2000 Washington Street (RTN 3-25822), which is an Unclassified Waste Site where a release of TCE, 1,2-dichloroethene, and 2-hexanone occurred; a Proposed Parking Facility located at 710-710A Albany Street (RTN 3-4159); the former National Lead Co. located at 800 Albany Avenue (RTN 3-0245), which is a Tier II site where a release of an unknown chemical occurred and the former Bowen Cleaners located at 2326-2328 Washington Street (RTN 3-4461) which is a former drycleaner and Tier II site where a release of an unknown chemical occurred from drums. In addition, 3 locations where underground storage tanks have been identified or are listed as unclassified sites have been identified. • The Urban Ring’s preliminary alignment plans have been developed so as to facilitate development of the proposed South Bay Harbor Trail along the north side of Melnea Cass Boulevard. As the respective projects advance, further coordination on design details will be necessary to ensure that the compatibility established at the conceptual level continues and is further enhanced. During the engineering phase of the Urban Ring project, designs will be developed for the Melnea Cass Boulevard corridor that will be consistent with policies of the Roxbury Master Plan. This will include landscape, treatments to the extent possible along the corridor. Economic Development Issues • The project would increase the transit connectivity and capacity for the Melnea Cass Boulevard corridor, and enhance transit-oriented and smart growth development opportunities in this area. EOT has been coordinating with neighborhood groups and the City of Boston on roadway design and streetscape issues related to development parcels along the corridor. • The project would increase the transit connectivity of Dudley Square. EOT has coordinated with the City of Boston regarding the Roxbury Strategic Master Plan vision as well as with the development of publicly owned parcels at the Melnea Cass/Washington Street intersection and Dudley Square. 2.1.10 Sector 10: Dorchester Sector 10 of the LPA alignment extends from south of Albany Street to JFK/UMass Station in South Boston. It uses existing city roadways, with some proposed segments of bus lane. See Figures 2-9 and 210 for Sector 10 alignment of the LPA. The key transportation feature of Sector 10 is the provision of bus lanes on Massachusetts Avenue. Bus operations on Massachusetts Avenue would be improved by implementing segments of bus lane in both directions where conditions allow. Only one stop (Newmarket) would be provided between Albany Street and Edward Everett Square, so travel speeds and reliability would be improved. A new commuter rail connection would be developed at the Newmarket Station. Stations. The LPA includes three stations in this sector that would be located at: • Newmarket (Fairmount Branch commuter rail connection); • Edward Everett Square; and Urban Ring Phase 2 RDEIR/DEIS Page 2-35 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • JFK/UMass (Red Line and Old Colony commuter rail connections). These stations would provide connections with 5 MBTA bus routes and connections with the Fairmount Branch commuter rail at the planned Newmarket Station. Connections would be provided with the Old Colony Commuter Rail Line and the Red Line at JFK/UMass. Refer to Table 2-12 for a listing of connections. Future transit-oriented development opportunities are rated highly at the station locations. Urban Ring Service. Urban Ring service would be available on one BRT route: • Route 6 – JFK/UMass to Harvard Square via LMA, (headways = 7 minutes peak periods, 12 minutes for midday and Saturday, and 15 minutes for Sunday, holiday) This route would provide two connections with commuter rail and a connection with the Red Line at JFK/UMass Station. The Newmarket Station would be new providing new service and accessibility to the neighborhood. Route and Running Way • Mass Ave in bus lanes to Newmarket Station (Fairmount Branch connection) • Mass Ave in bus lanes to Edward Everett Square Station • Columbia Road in mixed traffic to JFK/UMass Station (Red Line and commuter rail connections) The alignment total for this segment is 2 miles, of which 46 percent would be separated running way. The mixed traffic portion is primarily along Columbia Road. Average travel speeds would be approximately 9 mph in each direction. Demographics. An estimated 26,500 people will live within a one-half mile walk of one of these four stations, and 16,400 people will work within one-half mile of a station by 2030, the project horizon planning year. More than three-fourths of residents near these stations live in TAZs that meet regional Environmental Justice criteria. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. More detailed summary information is provided in Chapters 4 and 5. Transportation Issues • Coordination with the City of Boston regarding the removal of on-street parking on segments of Massachusetts Avenue to provide bus lanes. • Coordination with MBTA on connections between the Urban Ring service and the planned new commuter rail station on the Fairmount Branch at Newmarket. Environmental Issues • Coordination will be necessary with respect to bus operations adjacent to Richardson Square and Columbia Road park. Further coordination with the BRA and Boston Parks Department on design details will be necessary to ensure that the compatibility established at the conceptual level continues and is further enhanced. • A potential project benefit is the improved cross-town access to the Joseph Moakley Park and Carson Beach recreational areas, as well as the Harbor Walkways on Harbor Point. Urban Ring Phase 2 RDEIR/DEIS Page 2-36 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Economic Development • The project would increase the transit connectivity and capacity for the station locations, and enhance transit-oriented and smart growth development opportunities in this area. 2.1.11 Sector 11: South Boston/ World Trade Center Sector 11 of the LPA alignment extends from the west end of Albany Street at the I-93 service road to midpoint of the I-90 Ted Williams Tunnel. It uses existing local and Massport roadways with bus lanes provided on A Street. See Figure 2-11 for Sector 11 alignment of the LPA. The key transportation features of Sector 11 alignment include a direct route between the Crosstown corridor and the Seaport area of South Boston and the World Trade Center. Bus lanes are proposed along A Street in both directions. The project would also utilize the new Seaport District roadways around the World Trade Center. The project would connect with the Red Line at Broadway Station and Silver Line BRT at World Trade Center. Stations. The LPA includes three stations in this sector that would be located at: • Broadway (Red Line connection); • A Street; and • World Trade Center (Silver Line connection). These stations would provide connections with 11 MBTA bus routes and connections with the Red Line at Broadway and the Silver Line at World Trade Center. Refer to Table 2-13 for a listing of connections. Future transit-oriented development opportunities are rated highly at the station locations. Urban Ring Service. Urban Ring service would be available on one BRT route: • Route 7 - Yawkey Station to Mystic Mall (headways = 10 minutes peak periods, 15 minutes for midday and Saturday, and 20 minutes for Sunday, holiday) This route would provide one connection with the Red Line at Broadway Station and one connection with Silver Line BRT at World Trade Center. The alignment total for this segment is 4 miles, of which 9 percent would be separated running way and 91 percent would be mixed traffic. The mixed traffic portion would include Broadway and Massport roadways in the Seaport District. Average travel speeds would be approximately 12 mph in each direction. Demographics. An estimated 36,600 people will live within a one-half mile walk of one of these four stations, and 88,000 people will work within one-half mile of a station by 2030, the project horizon planning year. Approximately 5,200 residents near these stations live in TAZs that meet regional Environmental Justice criteria. Outstanding Issues. The following is a summary of key transportation, environmental and economic development issues in this sector. These are issues that will need to be addressed in future preliminary engineering and design stages of the planning and environmental review process. More detailed summary information is provided in Chapters 4 and 5. Urban Ring Phase 2 RDEIR/DEIS Page 2-37 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Transportation Issues • Coordination with the City of Boston to identify potential opportunities for bus lanes on A Street. Environmental Issues • Within this Sector, open sites with identified hazardous materials include Reflex Lighting located at 10 Silver Street (RTN 3-25513), which is an Unclassified Waste Site related to a release(s) of lead, benzo(a)anthracene, and benzo(e)acephenanthrylene in soil. In addition, 5 locations where underground storage tanks have been identified or are listed as unclassified sites have been identified. Economic Development • The project would increase the transit connectivity and capacity for the station locations, and enhance transit-oriented and smart growth development opportunities in this area. In particular the project would improve transit connectivity for the A Street corridor by providing improved connectivity to the Red Line at Broadway Station and the Silver Line at World Trade Center Station.

The following categories are summarized below: • Transit; • Local Traffic, Pedestrians and Bicycles; • Regional Traffic; and • Phase 3 Compatibility. 2.2.1 Transit The Locally Preferred Alternative (LPA) would provide several transit-related advantages over the Baseline Alternative as noted below. Dedicated Right-of-Way for Exclusive Bus Use. The LPA would comprise a coordinated system of exclusive busways (both surface and tunnel long and short), bus lanes, and mixed traffic BRT operation. The alignment recommendations are designed to maximize the amount of dedicated busways and bus lanes in congested areas of the corridor, and to allow mixed traffic operations primarily in areas with lower levels of traffic congestion and delay. These features would allow BRT vehicles to bypass general traffic congestion and queuing which results in travel time savings and greater schedule reliability. Bus lanes would also permit bicycle travel where separate bicycle lanes cannot fit on the road. Bus queue-jump lanes. The LPA would include bus queue-jump lanes, which are short priority lanes for buses that are typically combined with traffic signal priority improvements. The intent of the bus queuejump lane is to allow the higher-capacity vehicles to cut to the front of the queue, reducing the delay caused by the signal and improving the operational efficiency of the transit system. Bus queue-jump lanes consist of a travel lane on the approach to a signalized intersection which is often restricted to transit vehicles only. A queue-jump lane is generally accompanied by a signal which provides a phase specifically for vehicles within the queue jump. Such a signal reduces the need for a designated receiving lane, as vehicles in the queue-jump lane get a "head-start" over other queued vehicles and can therefore merge into the regular travel lanes immediately beyond the signal. Thus, the idea is to enable buses to by-pass queues of traffic waiting at a busy intersection, allowing faster travel times for buses. Ambulances and emergency vehicles would also be allowed to use queue-jump lanes. Vehicle Technology. The LPA BRT service would use a fleet of diesel-electric hybrid buses. Advances in engine and battery technology are expected to enable these diesel-electric hybrid buses to operate efficiently, reliably and with low emissions throughout the Urban Ring system, including zero-emission operation for the full length of the tunnel. Enhanced Transit Identity. An important element of the LPA is to create a transit identity for the Project. This would consist of distinctive low-floor 60-foot articulated buses; state-of-the-art stations with consistent materials and design features; and traveler amenities such as real-time information and prepay boarding options. The BRT buses would accommodate between 90 to 120 passengers. These elements would create a transit identity for the LPA that would improve the quality and enjoyment of service. Ridership. The LPA would carry approximately 191,700 daily riders on the proposed Urban Ring service (BRT and CT routes), and would increase overall project ridership over the Baseline Alternative by 127,000 daily riders. By providing more direct routes between key origin and destination points, the LPA would reduce demand for the heavily-used Green Line light rail service and would relieve transit congestion in the central subway system of Boston. The LPA would reduce the number of riders on Urban Ring Phase 2 RDEIR/DEIS Page 2-59 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Green Line service in the central subway by approximately 2,600 riders in the AM peak hour compared to the Baseline, representing 15 percent reduction in riders. The LPA would increase ridership for commuter rail service over the No-Build Alternative by 9,200 daily riders. High Frequency Service. Headways of 10/15/20 minutes for BRT buses are proposed for peak, midday/Saturdays and Sundays, holidays and evenings, respectively. The five BRT routes would overlap in most areas resulting in headways of approximately 3 minutes, which is comparable to rapid transit service. Travel Time Savings. The LPA results in higher travel speed of 14 mph compared with 11 mph for the Baseline Alternative. The LPA results in 40-45 minute travel time savings over the Baseline Alternative for the entire length of the corridor. These travel time advantages result in higher ridership demand for the Urban Ring project. Reliability. In addition to travel time savings, the LPA would provide more reliable service for riders. The bus lanes, busways and tunnels provide exclusive BRT running ways which are not impacted by general traffic, delivery trucks, and non-vehicular conflicts. These features allow BRT buses to travel according to schedule without encountering delays that are typically experienced in mixed traffic. In addition, the LPA BRT routes have been developed to generally avoid congested roadways and intersections in the study area to the extent possible. The result of these advantages is a reliable service provided to riders on a daily basis. The travel advantage features have been used to evaluate ridership and travel time for each of the project alternatives. Mode Share. The LPA would result in increased transit mode share (8.3 percent) in the region over the Baseline (8.1 percent) and No-Build (7.9 percent) Alternatives. As a result, the LPA would eliminate approximately 41,500 daily auto person trips compared to the No-Build and 24,200 trips compared to the Baseline. These transit mode share increases are considered significant and positive benefits of the Urban Ring project. 2.2.2 Local Traffic The LPA would minimize the impacts on general traffic and pedestrians relative to the Baseline Alternative due to bus signal priority; tunnels, busways and bus lanes; pedestrian features; and bicycle features. Bus Signal Priority. Bus signal priority equipment would be installed at many of the signalized intersections in the study corridor in order to improve transit travel time and reduce overall person-delay (based on delay weighted by bus occupancy). The bus signal priority system is designed to minimize impacts to general traffic where general traffic that operates during the same phases as the bus movements would experience additional intersection green time as a result of bus signal priority. Because of these features the impact to general traffic would be minimized under the LPA. In order to implement the proposed traffic signal bus priority operations strategy for Urban Ring Phase 2 BRT, it is necessary to provide new and upgraded traffic signal equipment at the signalized intersections (existing and proposed) within the Urban Ring Project Corridor. These intersections are controlled by a number of different jurisdictions including the cities of Boston, Cambridge, Somerville, Everett, Chelsea; the Town of Brookline; Massport and the DCR. It is proposed that new and upgraded equipment at these locations be provided as part of the Urban Ring Phase 2 BRT project, and that the various jurisdictions continue to be responsible for operations and maintenance of the signal systems. An agreement would be necessary between the EOT/MBTA and each jurisdiction to provide the desired traffic signal bus priority operation as well as continued maintenance of equipment necessary for providing such operation. Tunnels, Busways and Bus lanes. The busways and bus lanes would be made available not only for the new Urban Ring buses, but also for other existing bus and shuttle services, as well as emergency Urban Ring Phase 2 RDEIR/DEIS Page 2-60 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE vehicles (where appropriate).5 This would improve the reliability of buses and shuttles and reduce congestion in general travel lanes. Pedestrian Features. The LPA would signalize some intersections that are currently unsignalized and upgrade equipment at many signalized intersections. Pedestrian signal equipment would be provided and upgraded at these locations. Appropriate pedestrian crossing signal timings would be provided. The LPA alignment and stations have been developed to be consistent with and complement existing and planned pedestrian facilities in the study corridor including mixed-use paths. Measures have been developed to separate bus travel from pedestrian and bicycle facilities. The LPA would also increase pedestrian safety and comfort by providing medians at locations such as the Melnea Cass Boulevard. Bicycle Features. Bus lanes could also allow bicycle travel where separate bicycle lanes cannot fit on the road. Bus/bike lanes operate well in many cities in North America. In addition, bicycle racks would be provided at station locations and buses would be equipped to permit bicycles either on front racks or on board. 2.2.3 Regional Traffic By providing improved transit access and capacity, the LPA would make transit more attractive. This would result in a mode shift from automobile travel to transit travel for a total of 24,200 person-trips per day compared to Baseline Alternative. This in turn would result in 80,500 fewer daily vehicle miles traveled (VMT) on regional roadways than the Baseline Alternative, and 6,700 fewer vehicle hours traveled (VHT). This would have a positive impact on air quality, as discussed below in the Environmental summary. 2.2.4 Urban Ring Phase 3 Compatibility The proposed bus tunnel alignment and cross section in the Urban Ring Phase 2 LPA was developed to facilitate potential later conversion of the tunnel to rail transit operations in Urban Ring Phase 3. As a base case for comparison, the Phase 2 horizontal tunnel alignment considered the Urban Ring Phase 3 rail transit alternatives between Sullivan Square and Dudley Square as previously identified in the Urban Ring MIS and presented in the 2004 DEIR. In addition, the analysis of Phase 3 compatibility also recognizes the potential for long range rail transit service connections to Allston, a travel market whose high growth rate was not yet recognized in the MPO land use projections at the time the MIS was completed. The Phase 3 compatibility test included three categories: basic compatibility (i.e. tunnel cross section and alignment criteria); basic features (i.e. portal elements, station elements, turnouts etc.); and advanced features (i.e. detailed elements of rail functionality). Major structural elements required for Phase 3 that could be built during Phase 2 may include: • Dedicated underground turnout structures consistent with potential Phase 3 rail alignments; • Longitudinal extension of underground stations to allow for Phase 3 platform lengths; • Vertical extension of underground stations to allow Phase 3 station platforms to be built beneath the Phase 2 station (such that both BRT and rail could operate simultaneously, if this were the recommendation of future Urban Ring Phase 3 planning and environmental review); and 5 Tunnels will be considered for use by other buses and shuttles but must have appropriate dual mode equipment so they can use electric propulsion in tunnel sections. Urban Ring Phase 2 RDEIR/DEIS Page 2-61 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE • Construction of a larger diameter tunnel to incorporate two decks - an upper deck for BRT, fitted out during Phase 2, and a lower deck provided during Phase 2 and fitted out for rail during Phase 3. In general, where cut-and-cover structures are required for tight turns in Phase 2, these would be built to incorporate Phase 3 turnouts. In addition, where portals are required to be re-graded during Phase 3 conversion, the portals would be designed and constructed to accommodate these requirements in Phase 2. 2.3 Maintenance Facilities The BRT vehicle fleet needed to provide the services described in the LPA would require bus maintenance facility capacity beyond that currently available from existing MBTA bus maintenance facilities. Urban Ring Phase 2 bus maintenance operations would be split among two facilities: the existing Southampton Street maintenance facility and a proposed Wellington Bus Maintenance Facility. In 2002, the MBTA initiated a separate Bus Maintenance Facilities Strategic Plan to “develop a Strategic Plan for bus operations that identifies the short, medium, and long-term facility needs based on changes in fleet size, technology, and composition; fleet maintenance requirements; service delivery characteristics; and new service initiatives, specifically the Urban Ring.”6 Bus fleet size estimates for the Baseline Alternative (referred to in that study as Urban Ring Phase 1) were identified in the MIS. These bus fleet size estimates have been updated and are being coordinated with MBTA’s Bus Maintenance Facilities Strategic Plan. The key recommendations contained in the Final Strategic Plan for Bus Maintenance Facilities are being advanced by MBTA as separate projects and are summarized below. The Urban Ring would contribute a prorated share of the cost of the bus maintenance facilities based on the number of Urban Ring vehicles as a percentage of total vehicles maintained. The number of BRT buses needed to operate each of the Phase 2 routes in the LPA and Baseline was estimated using the round trip length of each route, calculating the total round trip cycle time including all station dwells, and dividing the total cycle time in minutes by the planned 10-minute peak period headway of BRT1, BRT2 and BRT 7 and 7-minute peak period headway of BRT5 and BRT6. Average roundtrip speeds, including station dwell, for the proposed routes during the AM peak period in the year 2030 were projected based on the total cycle time, including all station dwell time. The cycle times and speeds are a function of route length, the percentage of busways and bus lanes, and the forecast level of congestion in mixed traffic segments using ITS bus signal priority. Table 2-14 presents the summary of BRT vehicle fleet size requirements by route for Baseline and LPA. It shows that for the Baseline Alternative, the estimated fleet size for all five CT routes combined is 105 vehicles including layover considerations and spares. The total BRT fleet size for LPA is 65 vehicles, including layover considerations and spares. 6 Final Strategic Plan for Bus Maintenance Facilities, MBTA, April 2003.

Per the requirements of the NEPA process, direct, indirect, and cumulative impacts were considered; the categories of impacts defined by the Council on Environmental Quality (40 CFR §§ 1508.7 and 1508.8) as follows: • Direct impacts are caused by the action and occur at the same time and place. • Indirect impacts are caused by the action and are later in time or farther removed in distance, but are still reasonably foreseeable. Indirect impacts may include growth inducing effects and other effects related to induced changes in the pattern of land use, population density or growth rate, and related effects on air and water and other natural systems, including ecosystems. • Cumulative impacts are the impacts on the environment which result from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (federal or non-federal) or person undertakes such other actions. Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time. For the analysis of cumulative impacts of the LPA, the following regional transit projects have been considered: o Fairmount Line Corridor Improvements – Program to improve facilities, infrastructure, and service on the Fairmount commuter rail line (implementation ongoing) o Green Line Extension – Project to extend existing Green Line service from Lechmere Station through the northwest Boston corridor communities of Cambridge, Somerville, and Medford, with an extension of the main line to Medford and a spur line to Union Square in Somerville (conceptual engineering and preparation of state and federal environmental review documents) Urban Ring Phase 2 RDEIR/DEIS Page 2-63 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE 2.4.1 Land Use and Economic Activity Direct Impacts o The LPA would improve connections among life sciences institutions and companies, and enhance connections between life sciences jobs clustered in Boston and Cambridge and the regional workforce. o The LPA would provide improved linkages between residential communities and existing and emerging employment centers in the corridor, and better connections among the many educational, medical, and research institutions and businesses concentrated there. o To construct the LPA, the total capital cost expenditures associated with the cities, towns, and counties along the corridor would be an estimated $1,965.4 million (in 2007 dollars). In terms of employment, an estimated 11,265 new jobs would be created directly over the construction period. o Operating and maintenance costs for the LPA have been estimated at $30 million to $40 million per year. Direct, permanent project employment is anticipated to be 200. Indirect Impacts o Improved transit service would benefit target economic zones that are located in or immediately adjacent to one or more LPA catchment areas, assuming that transit-related land uses are planned for or exist within the area, and assuming also that supportive municipal policies are in place. o With the LPA in place, workers would be able to get to work in the life sciences cluster and in other employment centers in the greater Boston area easier, increasing the attractiveness of these centers as places of work. In turn, this would enable the growth and expansion of the employment centers, bolstering the regional economy. o The regional input-output model system (RIMS II) estimates that indirect economic activity, as a result of project construction, would be $2,199 million in the three-county region; 8,240 new jobs would be created indirectly over the construction period. o Indirect economic output from the project’s annual operation expenditures is estimated at $47.9 million; indirect, permanent jobs total 184. Cumulative Impacts o Both the Fairmount Line Corridor Improvements and the Green Line Extension would increase access to target economic zones, and, in combination with the LPA, would benefit these zones. o Cumulatively, these regional transit projects and the LPA, by increasing the attractiveness of the life sciences cluster and other employment centers as places of work, would enable the growth and expansion of the employment centers, bolstering the regional economy. Urban Ring Phase 2 RDEIR/DEIS Page 2-64 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE 2.4.2 Displacements and Relocations Direct Impacts o Construction and implementation of the project would require some property takings along the corridor for construction of project elements including BRT busways and BRT stations. The anticipated ROW requirements of the LPA total 27.32 acres, comprising 8.90 industrial/commercial, 6.54 acres institutional/municipal, and 11.88 acres railroad right-of-way. There are no residential takings or business relocations associated with the project.7 2.4.3 Neighborhoods and Population Direct and Indirect Impacts o The LPA would not have disproportionately high and adverse effects on the minority or low-income populations in the corridor or the seven-city region. The LPA also would provide benefits to residents including the minority and low-income populations living near the stations. These benefits include improved access to transit, transit travel time savings, expanded access to employment and amenities, and the potential for increased economic development. 2.4.4 Visual Resources and Aesthetics Direct Impacts o Construction of BRT busways, and mixed traffic and exclusive bus lanes at various locations along the corridor, would not result in adverse visual impacts at any location. Construction of BRT stops and other corridor-wide improvements would greatly enhance the visual and aesthetic qualities of the place where such facilities are planned. 2.4.5 Air Quality Indirect and Cumulative Impacts o Given the significant anticipated reduction in VMT and introduction of low-emission vehicles, air quality benefits would be realized as part of the LPA. The LPA would improve air quality at the intersection, municipal, and regional levels compared to the NoBuild and Baseline Build Alternatives, largely due to the project’s ability to divert automobile trips to public transportation. A microscale analysis indicated that maximum 1-hour and 8-hour carbon monoxide (CO) concentrations remain the same for Project Build and No-Build scenarios, but future year CO concentrations are generally below existing levels due primarily to future year emission controls required by federal regulations. A mesoscale analysis demonstrated that the LPA exhibited the lowest emissions of all future cases, while the no-build case exhibited the highest emissions because increased public transportation reduces the number of individual motor vehicles in the project area. Regarding fine particulate emissions, the introduction of ultralow sulfur diesel (ULSD) fuel in 2007, along with future emission standards (established under state and federal regulations) would significantly reduce fine particulate emissions 7 One of the Allston route options still under consideration would impact an existing business at the north end of Malvern Street, Boston, only if selected as the recommended option. Analysis of Allston route options is ongoing. Urban Ring Phase 2 RDEIR/DEIS Page 2-65 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE from on-road diesel powered vehicles in future years. ULSD is currently used by the MBTA in its bus fleet. 2.4.6 Noise and Vibration Direct Impacts o The construction and operation of Urban Ring Phase 2 is not expected to have severe noise impacts on sensitive receptors in the corridor, defined as noise that can cause significant percentage of people to be highly annoyed. Any noise from the project’s construction or operation is projected to fall within an acceptable range of existing ambient noise conditions. Because most of the construction on the proposed bus alternatives would primarily be street improvements, the primary locations for assessing construction noise impact would be at the proposed portals for the tunnel boring machine and the stations in the LMA. Potential construction noise impacts will be evaluated during engineering and design of the project, as more details of the construction scenarios are known, including potential haul routes for excavated material. o The only portions of the proposed LPA with the potential for operational vibration impact from bus operations are within the LMA and MIT. However, based on the ambient vibration measurements conducted in these locations, the bus operations are not projected to generate vibration levels higher than existing vibration generated by current buses, trucks, and deliveries to buildings. In addition, because the primary source of vibration from rubber-tired vehicles is from roadway irregularities such as potholes, it is expected that buses operating on newly-constructed busways or in the proposed tunnel would generate lower vibration levels than are currently experienced from buses and trucks on existing streets. Construction vibration levels would have the most impact during tunnel construction operations in the LMA. This area has a range of sensitive locations including residential locations and research facilities with vibration-sensitive equipment. As more detailed information regarding soil conditions, specific equipment locations and building coupling losses becomes available during final design, more accurate assessments for each piece of equipment can be made. 2.4.7 Plant and Animal Species and Habitats, and Water Resources and Wetlands Direct Impacts o The proposed busway may impact wetlands and other habitats associated with the Malden River. Bordering vegetated wetlands, characterized as a palustrine emergent wetland and dominated by common reed and broad-leaved cattail, are located along both sides of the Revere Beach Parkway east of the proposed Malden River crossing. o The proposed Charles River crossing may impact wetlands and other habitats associated with the river, including the river itself. o The impacts may include filling or altering wetland or aquatic habitats. Detailed delineations of these resources would be conducted as required during the future design phase of the project. All wetland and water resource impacts would be minimized to the extent practicable. Any impacts to wetland or water resources would be mitigated to Urban Ring Phase 2 RDEIR/DEIS Page 2-66 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE compensate for any loss of water resource area or function. The mitigation requirements would be worked out through consultation with the conservation commissions of the affected communities. 2.4.8 Energy Direct Impacts o Direct impacts are characterized by the energy that would be used for the construction of the Urban Ring facilities and operation of the BRT system. Direct impacts include the energy consumed by operation of the BRT vehicles, lighting for stations and bridges, and lighting and ventilation for tunnels. Indirect Impacts o Indirect impacts include changes in energy use by the regional transportation system – including automobiles, buses, trucks, and motorcycles – that would be caused by operation of the BRT service. As stated in Section 2.2.3, the LPA would result in a mode shift from automobile travel to transit travel and, thereby, 81,300 fewer daily VMT on regional roadways than the Baseline Alternative. At the regional level, this in turn would result in a reduction of 483 BTUs per day compared to the Baseline Alternative and in a reduction of 1,131 BTUs per day compared to the No-Build Alternative. 2.4.9 Hazardous Materials Direct Impacts o Proposed management activities in and around the numerous 21 E sites (locations where unintended releases or spills of hazardous materials have been reported) known to exist within the Phase 2 corridor include: developing a soil pre-characterization program, formulating a formal health and safety plan, and developing a contaminated soil and groundwater management plan. These measures have not been conducted at this time, but they will be completed as part of later phases of the project. o DEP has recommended that the MBTA consider combining the numerous 21 E sites using the single Special Project Designation provisions outlined under 21E and the Massachusetts Contingency Plan (MCP). It is intended that this recommendation will be adopted, but the application for the Special Project Designation has not yet been completed. Numerous 21 E sites are located in the vicinity of the Urban Ring corridor and several of these sites are owned by the MBTA. The MTBA is currently working to remediate several of these sites, including the Commuter Rail Maintenance Facility, Wellington Station, and Sullivan Square Station. 2.4.10 EMF and Moving Metal Direct Impacts o The only portions of the LPA with a demonstrated sensitivity to electro-magnetic field (EMF) and moving metal impact from bus operations are the LMA and MIT. Magneticfield fluctuations from the Urban Ring Phase 2 are expected to have a frequency spectrum of 0 to 10 Hz and to occur approximately every few minutes due to the intermittency of bi-directional transit service. The highest magnetic fields are expected at grade, at the edge of the right-of-way. It is unlikely that Urban Ring Phase 2 BRT vehicles Urban Ring Phase 2 RDEIR/DEIS Page 2-67 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE would cause an EMF/EMI impact or would necessitate EMF/EMI mitigation. Additional study on potential EMF/EMI impacts is required during preliminary engineering. Mitigation o If mitigation is required, there are three independent mitigation strategies: Increase separation distance, decrease electric currents, and cancellation. EMF/EMI increases with the magnitude of the currents in the source and decreases with the distance away from the source. Along the lines of cancellation, opposing supply currents can be places as close to each other as possible to cancel effects at greater distances, or local coils can be used to cancel disturbing magnetic fields. Another type of EMF/EMI mitigation at the receptor location is placing high-permeability ferromagnetic “mu-metal” sheets in locations that shunt the magnetic field lines away from sensitive areas. 2.4.11 Historic and Archaeological The project corridor for the LPA is the result of combining individual elements from the nine Build and three Hybrid Alternatives. The Area of Potential Effect (APE) includes almost 240 individual properties and 45 areas that are listed in or determined eligible for listing in the National Register of Historic Places, as well as several areas that have been identified as archaeologically sensitive (see Table 2-15). There are also a number of local historic districts located along the LPA corridor. There is also the potential for additional eligible properties within the corridor of the LPA. Reconnaissance level survey will be needed for significant portions of the LPA to verify currently inventoried properties, evaluate those properties that have been inventoried but not evaluated, and to identify additional properties. The APE is defined as “the geographic area within which the undertaking may cause changes in the character of or use of historic properties, if any such properties exist” [36 CFR 800.16 (d)]. For the purposes of the Urban Ring, the APE was established as a corridor extending from 50 feet (existing streets) to 100 feet (rail corridors and new right-of-way) left and right from the centerline of the proposed route. At BRT station locations, the APE was expended to encompass150 feet around each station location, depending on the type of BRT station. For proposed bus shelters the APE was limited to the surrounding streetscapes, while larger bus stations required a larger APE. An historic property is defined as “any prehistoric or historic district, site, building, structure, or object included in, or eligible for inclusion in, the National Register of Historic Places maintained by the Secretary of the Interior” [36 CFR 800.16(l)]. The majority of the Urban Ring LPA is not expected to have any impact on historic properties located along the proposed corridor. By utilizing the existing street network and operating in mixed traffic and bas lanes, the LPA would avoid historic properties, provided that the bus lanes are within the existing street and do not require additional right-of-way. However, there are specific elements of the LPA, the proposed tunnel option and busway routes on new locations that may have direct and/or indirect impacts to historic properties. This section discusses each sector of the LPA, summarizing the historic properties within the APE, the potential impacts to each property as a result of implementing the LPA, and a preliminary finding of effect. Sector 1: East Boston/Logan Airport The LPA corridor between the Ted Williams Tunnel and the Chelsea River contains three previously inventoried individual properties and one area that have been determined potentially eligible or recommended eligible for listing in the National Register (see Table 2-15). The LPA traverses through the Chelsea River Industrial District (BOS.RO) on a busway located within an abandoned railroad right of way. As long as all construction activities occur within the right of way no impacts to this resource are anticipated. The LPA approaches and crosses the Chelsea River in mixed traffic and therefore would not impact the MDC Sewage Pumping Station (BOS.19), Chelsea Street Bridge Tender House, or the Urban Ring Phase 2 RDEIR/DEIS Page 2-68 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Chelsea Street Bridge (CLS.900) which is to be rebuilt by others. Two BRT Stations are proposed within Sector 1. Both are located within existing structures, the Logan West Garage and the Airport Blue Line and would have no impact on any historic properties. There are no areas of archaeological sensitivity within Sector 1 of the LPA.

The LPA through Chelsea is located within an abandoned railroad corridor and adjacent to the MBT Rockport Commuter Rail line. The LPA passes the Russell Box Company (CLS.608-610) and surveyed properties 960 and 961 in a depressed section of the abandoned railroad and abuts the northern edge of the Bellingham Square District (CLA.A) within the existing commuter line right of way. As long as all construction activities for the busway are contained within the rail right of way (both abandoned and active) no impacts to historic properties are anticipated. Three BRT stations are proposed. The stations at Griffin Way and Everett Avenue/Mystic Mall are stand alone shelters, while the Chelsea Commuter Rail location is an existing station that is proposed for upgrading and lengthening of the station platforms. None of the proposed stations are anticipated to have any impact on historic properties. There are no areas of archaeological sensitivity within Sector 2 of the LPA.

In addition, there are nine individual properties within the Broadway-Charlton Street Industrial District that have been inventoried but not evaluated (see Table 2-17). The LPA bypasses the ParisGarvey-Springs Streets District within the Rockport commuter rail line right of way. The proposed surface busway is separated from the district by the commuter line and is not anticipated to have any impact on the district. In the vicinity of the Broadway-Charlton Street Industrial District the surface busway is within the Rockport commuter rail line, north of the existing tracks and is not anticipated to have any impact on the district. The LPA busway would run parallel and north of the Revere Beach Parkway and cross the Malden River on a new bridge structure placed adjacent to the Woods Memorial Bridge. The construction Urban Ring Phase 2 RDEIR/DEIS Page 2-69 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE of the busway may have direct and indirect impacts (visual) to the Revere Beach Parkway, resulting in a finding of adverse effect. The Massachusetts Department of Conservation and Recreation (MADCR) is planning to replace the Woods Memorial Bridge and would construct a temporary bridge to the north. Negotiations are currently underway for the temporary bridge to remain in place to carry the busway over the Malden River. Consequently, the proposed busway would have no impact on the Woods Memorial Bridge. Only one BRT station is proposed, the stand alone bus shelter at Gateway, Everett would have no impact any historic property. The project corridor adjacent to the Malden River is considered archaeologically sensitive for both terrestrial and marine resources dating from the precontact/contact/post contact periods and survey is recommended to determine the presence/absence of potentially significant archaeological properties Table 2-17: Survey No. Historic Resources: Locally Preferred Alternative: Segment A - Sector 3 Potential Property Name National Register Status Impact Paris-Garvey-Springs Streets District Not Evaluated No Broadway- Charlton Street Industrial Not Evaluated No EVR.U District EVR.AA Revere Beach Parkway NRHD Yes Everett Factories-EFTC Not Evaluated No 975 EVR.196 #5 Loft Everett Factories-EFTC Not Evaluated No 976 EVR.195 #3 Loft Donovan, James Shoe Not Evaluated No 977 EVR.193 Co.

The LPA proceeds in mixed traffic along the Revere Beach Parkway and the Fells Connector Parkways and no impacts to either historic property are anticipated. The LPA then proceeds through Assembly Square and Sullivan Square via a combination of mixed traffic and bus lanes on existing streets before entering a surface busway to New Lechmere Station. By utilizing a combination of mixed traffic and bus lanes within existing streets the LPA is not anticipated to have any impact on any of the inventoried properties. BRT stations are proposed at Wellington Station, Assembly Square, Sullivan Square, and Cobble Hill (Inner Belt). Except for Sullivan Square and Wellington Station, these stations are stand alone bus shelters and would have no impact on historic properties. The existing Sullivan Station would be modified to include new commuter rail platforms beneath the I-93 viaduct. Although Sullivan Station is in close proximity to the Davidson Rubber Company-Davidson Syringe Company (BOS.4336) the proposed improvements to the station are not anticipated to have an impact on this property. Any improvements at Welling Station would be contained within the existing station. There are no archaeological sensitive areas within Sector 4 of the LPA.

Two National Register districts, East Cambridge Historic District (CAM.E) and Blake and Knowles Steam Pump (CAM.C) are located in Sector 5, as well as four individually listed properties, Blake and Knowles Smith Shop and Brass Foundry (CAM.355), Blake and Knowles Erecting and Assembly Building (CAM.356), Blake and Knowles Machine Shop #2, Worthington Place (CAM.357), and Blake and Knowles Machine Shop, #3 (CAM.358). In addition, there are 18 recently identified or inventoried properties that are considered potentially eligible for listing in the National Register (see Table 2-19). By utilizing the existing street network and operating in mixed traffic and bus lanes, the LPA is not expected to have any impact on any of the properties identified, provided that the bus lanes are within the existing street and do not require any additional right-of-way. Five BRT stations are proposed, the new Lechmere Station that is part of the Green Line project and four stand alone bus shelters at First Street/Galleria, Binney Street, Fulkerson Street, and Kendall Square. As each bus shelter is small in size no impacts to inventoried properties in anticipated. There are no archaeologically sensitive areas identified within Sector 5 of the LPA.

Three BRT stations are proposed; MIT/Mass Avenue, Cambridgeport, and Commonwealth Avenue/BU. Sector 6 of the LPA bypasses or traverses five districts: Audubon Circle (BOS.XB), Fort Washington (CAM.D), the Charles River Basin (CAM.A/BOS.CA), the Cottage Farm Historic District (BLK.A), and the Commonwealth Avenue Area (BKL.AO) (see Table 2-20). There are three individually listed properties: Boston University Bridge, Amos A. Lawrence-Bates House (BLK.28), and the Richard M. Lee House (BLK.27) as well as eighteen inventoried properties that have been recommended as eligible for listing in the National Register. There are four properties that contribute to local historic districts. In addition, there are ten recently inventoried properties that have not been evaluated (see Table 2-20A). The majority of the LPA in Sector 6 is within existing streets, either in mixed traffic or bus lane. Through these areas, the LPA is not expected to have any impact on historic resources. In the vicinity of the Fort Washington Historic District (CAM.D) the LPA crosses a vacant MBTA lot to access a proposed busway within the CSX corridor, crossing the Charles River on a reconstructed Grand Junction Railroad Bridge. The proposed alignment may result in an indirect impact (visual) on the Fort Washington Historic District. Furthermore, the placement of the Cambridgeport bus shelter should be carefully reviewed. A reconstructed railroad bridge over the Charles River has the potential to impact the Charles River Basin Historic District and the Boston University Bridge. Impacts could be direct (construction related) and/or indirect (visual), resulting in a finding of adverse effect. Furthermore, if the reconstruction of the Grand Junction Railroad Bridge requires new land takings on either shoreline, or new bridge abutments and piers in the river, additional archaeological investigations will be required to determine the sensitivity of potentially undisturbed areas. Within Brookline and Boston the LPA is in mixed traffic and bus lanes within existing streets and impacts to adjacent historic resources are not anticipated, provided that bus lanes are within the existing streets and do not require any Urban Ring Phase 2 RDEIR/DEIS Page 2-72 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE additional right-of-way. The stand alone bus stations at MIT/Mass Ave and Commonwealth Ave/BU are small in size and no impacts to inventoried properties in anticipated.

Consequently, the LPA has not been finalized and several options are under consideration including surface and elevated busways, and mixed traffic and bus lanes along existing streets. The various options traverse or pass at least eight historic districts and seven individual properties (see Table 2-21). An additional 35 properties have been inventoried but not evaluated (see Table 2-21A). LPA Option A in Sector 7 entails surface busway through the Beacon Park Rail Yard or mixed traffic along Commonwealth Avenue Brighton Street and Cambridge Street to Harvard Square. As such Option A is not expected to have an impact on any historic resources. Option A does entail the construction of a new BRT station in the rail yard. This structure would not have any impact on above ground resources. The archaeological sensitivity of the rail yards is considered low to moderate and the construction of a busway and the proposed bus station will require archaeological investigations to determine the presence/absence of potentially significant archaeological sites. The remaining stations include three stand alone bus shelters at Allston/Cambridge Street, Stadium Way/Western Avenue, and Harvard Square Station, as well as the existing underground bus station at Harvard Square.

The archaeological sensitivity of Beacon Park Rail Yards is low to moderate and the placement of piers for the viaduct has the potential to impact archaeological sites. Furthermore, the location of the proposed new Stadium Way has been assigned moderate archaeological sensitivity for both deeply buried precontact/contact period Native American sites (fish weirs, shell middens) and documented post-contact residential/commercial/industrial sites. Survey is recommended for each area to determine the presence/absence of archaeological sites. A new Stadium Way may also have an impact on above ground resources.

The majority of BRT stations under Option C are stand alone bus shelters that are not expected to have an impact. In summary, the final alignment of the LPA in Sector 7 has the potential to impact both above and below ground historic properties, resulting in a finding of adverse effect. Urban Ring Phase 2 RDEIR/DEIS Page 2-75 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE Sector 8: Boston/Fenway/Longwood Meadow The majority of the proposed LPA in Sector 8 is contained within a tunnel with surface busway, bus lane, and mixed traffic at either end of the tunnel. Prior to construction of the tunnel an interim plan for the LPA through the Longwood Medical Area consists of bus lanes and mixed traffic along existing streets. The Boston/Fenway/Longwood Meadow contains a number of historic districts and individual properties that are listed in or eligible for the National Register (see Table 2-22). The surface option for the LPA is contained within existing streets and is not expected to have an impact on historic properties, provided that no new right-or-way is required to accommodate the bus lanes and no ground disturbing activities occur outside of the existing streetscape. The tunnel option does have the potential to have an impact on a number of properties, especially during construction and operation (properties that may be impacted by the tunnel option are italicized in Table 2-22). The portals for the tunnel are located near the Green Line D Branch near the Landmark Center and north of Ruggles Street near Ruggles Station. The tunnel portal near the Landmark Center would be partially located on property occupied by Back Bay Yard, Riverway Administrative Building (BOS.7536), a National Register Property and impacts are expected to the property during construction, resulting in an adverse effect. Since the exact horizontal and vertical alignments of the proposed busway tunnels in this historic parkland and associated nineteenth-century neighborhood areas are not currently known, the tunnel routes are collectively assigned moderate archaeological sensitivity. There is one area of high sensitivity where the tunnel would extend through a recorded Native American (pre-contact) site area, MHC #19-SU-81, in the vicinity of the existing MBTA Ruggles Station near the intersection of Ruggles and Tremont streets.

The Eliot Burying Ground is also individually listed in the National Register and there are 12 individual properties that are potentially eligible for listing either as individual properties or as contributing properties to a district (see Table 2-23). The LPA utilizes a combination of dedicated busway and bus lanes along city streets. Four BRT stations are proposed, the existing Dudley Station and stand alone shelters at Washington Street/Silver Line, Crosstown Center, and at the Boston Medical Center. A bus station would also be integrated into the existing parking garage at Boston Medical Center. The LPA would run from Ruggles Station to the Washington Street Station via a busway down the center median of Melnea Cass Boulevard, from Washington Street Station to Dudley Square via mixed traffic and from Washington Street Station to the Boston Medical Center in mixed traffic and bus lanes on Albany Street. None of the elements of the LPA in Sector 9 are anticipated to have an impact on historic properties. By placing the busway within the median of Melnea Cass Boulevard, the need for additional right-of-way is eliminated. Utilizing mixed traffic and bus lanes would not impact any properties provided at no new right-or-way is required to accommodate the bus lanes. There are no archaeologically sensitive areas in Sector 9.

The findings may be “No Historic Properties Affected,” “No Adverse Effect,” or “Adverse Effect”. An adverse effect is defined as “alteration to the characteristics of a historic property qualifying it for inclusion in or eligibility for the National Register” (36 CFR 800.16(I)). Effects can be direct or indirect and can be immediate or reasonably foreseeable: cumulative, later in time, or at a distance. The majority of the Urban Ring LPA is not expected to have any impact on historic properties located along the proposed corridor. By utilizing the existing street network and operating in bus lanes and mixed traffic within the existing curb lines, the LPA would avoid historic properties throughout all but a small number of locations. There are specific elements of the LPA that may have direct and/or indirect impacts to historic properties that may result in a “finding of effect” and in some cases the effect may be considered “adverse” Each of these locations was included in the LPA only after an extensive review of alignment alternatives and options seeking to avoid or mitigate the potential effects while still addressing the purpose and need for the Project. In most cases, the impacts are temporary, associated with construction and would result in a finding of no adverse effect. Temporary and permanent adverse impacts have been identified on a preliminary basis at locations listed in Table 2-26. The proposed busway adjacent to Revere Beach Parkway in Everett would introduce an additional, parallel lane to this NR property that may result in direct (construction) and indirect (visual) impacts to this resource. However, the Revere Beach Parkway corridor in this area adjacent to the proposed busway is a general use parkway currently used by trucks and buses and the additional lane is not expected to result in a finding of adverse effect. The proposed shift of bus traffic from Albany Street to a busway within the CRX right of way would introduce new traffic patterns near Fort Washington Historic District and would require careful evaluation to determine if there is an adverse effect to this property. The proposed crossing of the Charles River on a rebuilt Grand Junction Railroad bridge may result in temporary direct (construction) and indirect impacts to the Charles River Basin Historic District and the BU Bridge. Careful review of the proposed design and construction methods for the rebuilt Grand Junction Railroad Bridge would be needed to determine if these impacts are an “adverse effect”. The construction of the portals for the proposed tunnel through the Longwood Medical Area would result in temporary construction and visual impacts to the Back Bay Yard, Riverway Administration Building and the Landmark Center, resulting in a finding of effect on these properties. However, the impacts are temporary and upon completion of construction the area would be restored to its current or improved conditions, resulting in a finding of no adverse effect. The proposed tunnel and underground stations beneath the Fenway and Longwood Medical Area were carefully evaluated to determine whether or not construction of the tunnel would result in vibrations that could directly impact above ground historic resources. The tunnel portals, alignments, and station locations of the LPA were modified during conceptual design to avoid any long-term adverse impacts on historic resources. Preliminary analysis of tunnel operations has indicated that the passage of rubber-tired buses through the tunnel would not result in any vibration that could impact above ground historic resources. During preliminary engineering and final evaluation of environmental impacts, additional analysis of subsurface conditions and tunnel construction methods would be conducted to confirm these preliminary findings, resulting in a finding of no adverse effect. Further survey and evaluation is needed in the Allston/Harvard area of the LPA to identify historic properties. Furthermore, the location of each stand alone bus shelter should be reviewed to confirm that there is no impact to surrounding historic properties. If any shelter is found to have an impact options for relocation or design should be considered. Further archaeological investigations are recommended wherever the LPA traverses new alignment (i.e. busways, the proposed tunnel) to determine whether there would be any impacts on significant archaeological sites.

This would impact park spaces in the Charles River Reservation. o Modifications to the Grand Junction Railroad Bridge would affect the water sheet of the publicly-owned Charles River. o Construction of a busway tunnel portal in the vicinity of the Landmark Center east and west of Park Drive would be immediately adjacent to the north and west sides of the Boston Parks and Recreation building used for office and storage/maintenance facilities. Impacts in the park portion of the project area would be temporary and construction related, and existing conditions would be restored once the tunnel is completed. o The small pocket park in Kendall Square (Galaxy Park) would be modified to accommodate the proposed exclusive bus lanes and bike lane connecting Third Street to Main Street at the Kendall Square MBTA Station. No major permanent adverse impacts to parks and open spaces are anticipated, although it is expected that the proposed actions would require Section 4(f) evaluations and Article 97 reviews. In addition, portions of some proposed Urban Ring BRT routes would utilize segments of DCR parkways. Most of the Urban Ring operations are proposed for general use parkways, so no adverse environmental consequences associated with bus use within the existing roadway is anticipated. Limited bus use of the Fenway, a pleasure-vehicle only parkway, is proposed for interim surface bus service for the Fenway and LMA areas. Table 2-27 below details the amount of publicly owned open space that would be temporarily or permanently impacted and thus require a Section 4(f) evaluation.

Most capital costs are incurred prior to start-up of the new service. O&M costs generally begin at system start-up and are ongoing for as long as the service is provided. O&M costs cover such items as labor, materials, and supplies to operate and maintain the transit vehicles, guideways, and other system infrastructure necessary to provide the scheduled service. 2.5.1 Capital Costs Table 2-28 provides a summary of capital costs for the LPA by major category in 2007 constant dollars. A geographic breakdown of the capital costs is provided in the LPA evaluation Tables 2-3 through 2-13.

The Federal Transit Administration (FTA) engaged a Project Management Oversight Consultant (PMOC) to undertake a review of the preliminary cost estimate for the Urban Ring Phase 2 LPA. The PMOC Urban Ring Phase 2 RDEIR/DEIS Page 2-86 November 2008 Chapter 2 LOCALLY PREFERRED ALTERNATIVE review identified a number of issues that introduce risk into this preliminary cost estimate. The most significant issues relate to uncertainty about a final tunnel alignment and construction methodology; assumptions related to dimensional and other specifications for the tunnel and underground stations (many of which were flagged as resulting in higher than expected cost estimates); and the lack of a definite project implementation schedule and mid-year of construction assumption. As a result, FTA is not able to endorse these cost estimates at this time. EOT recognizes these issues, which are principally related to the current state of conceptual engineering for the LPA, as appropriate to a draft environmental document. EOT will continue to work with FTA and the PMOC process to address these issues and ensure FTA endorsement of Urban Ring Phase 2 cost estimates as the project develops through preliminary engineering, final environmental review, and final design. The delivery method for the Urban Ring project could have an effect on the overall capital cost of the project. Traditional methods such as Bid-Build would be considered along with Design-Build methods. The Design-Build approach may offer more flexibility in terms of project delivery. 2.5.2 Operations and Maintenance Costs Preliminary Operations and Maintenance (O&M) costs were developed utilizing the operating statistics from the travel demand model run and unit costs for hybrid electric bus technology, and estimated using an average of the revenue vehicle miles and revenue vehicle hours methods. The O&M costs are shown in Table 2-29 for the LPA. Annual O&M costs for the Baseline Alternative (not shown) are expected to be higher than the LPA because the lack of bus lanes and busways in the Baseline Alternative result in slower route cycle times and the need for a larger fleet size to provide equivalent market coverage and service frequency as the Build Alternative (the LPA). The O&M costs shown in the table are preliminary and subject to revision based on final projected operating statistics from the regional model for the LPA and the Baseline Alternative. Table 2-29: LPA Operations and Maintenance Cost Summary O&M Cost Methodology Annual O&M Cost $ millions (2007 dollars) Revenue Vehicle Miles $40 Revenue Vehicle Hours $30 AVERAGE $35 Signal maintenance cost has not been assumed in the overall O&M costs of the project. The Urban Ring project has assumed costs for new signal equipment and upgrades at many intersection locations along the study corridor. The maintenance of signalized intersections will be coordinated between EOT, cities and towns and agencies. The Urban Ring LPA would reduce congestion in the Boston central subway. This would result in a cost savings on the existing operations and maintenance costs, particularly on the Green Line. This is noted as being a positive benefit of the Urban Ring LPA on existing transit infrastructure. Urban Ring Phase 2 RDEIR/DEIS Page 2-87 November 2008
