The purpose of this document is to define the specific elements of the TDM program and goals to reduce the traffic associated with the proposed Office/Research and Development Building to be located at 85 Walnut Street in Watertown, Massachusetts. The Project consists of the development of a 213,500 square foot (sf) Office/Research and Development Building with a total of approximately 566 parking spaces of which 102 parking spaces will be within a shadow parking level. Access to the Project will be provided by way of one full access signalized driveway onto Arsenal Street via an easement through the 101 Walnut Street property and one full access under stop-control shared driveway onto Walnut Street also provided through an easement. PLAN OVERVIEW The Proponent is committed to the implementation of a comprehensive (TDM) program as a part of the Proposed Office/Research and Development Building Master Plan Special Permit. Given the project's size, the Town requires a Comprehensive TDM Plan. The following TDM Criteria have been established in the Town's TDM Ordinance: ➢ Identify program goals and target(s) for trip reduction based on the project's proposed new trips and baseline transportation impacts. ➢ Provide a comprehensive list of TDM measures that will be used to guide the project's TDM program and achieve the program goal and trip reduction target(s). ➢ Provide a description of post-occupancy TDM measures, to determine the project's effectiveness in implementing the TDM program and achieving the program's goals for trip reduction target(s). ➢ Provide a schedule for post-occupancy TDM monitoring and reporting to the DCDP. ➢ Provide a list of corrective measures, including, but not limited to, additional TDM measures, additional incentives, or potential penalties to be applied by the Petitioner of the development/redevelopment to achieve the program goals and trip reduction target(s). GA8124 Watertown,MA\Report\6-TDM-85 Walnut TDM Plan.doe 3 TRAFFIC OVERVIEW A detailed Transportation Impact Assessment (TIA) was prepared for the overall project in conjunction with this TDM plan. A description of the project, trip generation, mode split commitments, employee trip origin data, current transit conditions and parking demand/supply are provided on the following pages. TRIP GENERATION As identified in the TIA, the traffic volumes expected to be generated by the proposed project were determined by using the ITE Trip Generation manual LUC 710, General Office Building for 213,500 sf. In addition, the unadjusted vehicle trips calculated using the ITE data were subsequently converted into person trips by applying national data for vehicle-occupancy rates for a variety of uses. The person trips were then adjusted to trips using mode split, vehicle occupancy. A summary table outlining the project vehicle trips is provided in Table 1.

GA8124 Watertown,MA\Report\6-TDM-85 Walnut TDM Plan.doe 7 TRAVEL DEMAND MANAGEMENT The Proponent is committed to reducing auto dependency by building tenants by implementing a TDM program. Per the Town's requirements, the TDM program will include quantifiable goals and a plan for collection and analysis of data to measure achievement of goals. A Comprehensive TDM Plan must achieve a minimum of 14 points based on the Town's point system with the goal of a 20% reduction in SOV use over time. The Proponent will work with the tenants through lease agreements to encourage TDM actions to the maximum extent feasible. The following TDM program elements will be implemented to Proponent's project: BIKE/PEDESTRIAN Improve Walking Conditions—1 Point The Proponent will provide upgraded pedestrian sidewalks along the entire frontage of the Site on Walnut Street, including curb and ramp replacement, and to installing new wheelchair ramps for ADA compliance, in accordance with MassDOT and Federal design guidelines and standards. The project design has incorporated many elements to provide convenient access and egress to/from Walnut Street to/from Arsenal Street and to encourage non-auto travel modes. The building design includes a courtyard facing east which provides the main pedestrian access to the building.Wayfinding signs will be installed to direct people to transit stops. Bicycle Parking—4 Points The Proponent will provide a minimum of 96 bicycle spaces, including 24 spaces on level 1 of the garage, 48 spaces on level 2 of the garage, and 24 indoor spaces to be located off the main entry lobby. It is important to note that all spaces will be in a visible and accessible location. Dissemination of area bicycle route maps, as may be available, will be posted in the building lobbies. Showers and Lockers—1 Point A shower facility will be located in the building to encourage employee mode shift to active, non-auto mode(walk/bike). GA8124 Watertown,MA\Report\6-TDM-85 Walnut TDM Plan.doe 8 Bike Repair Station—1 Point A bicycle repair station will be provided on the Site that contains basic tools necessary for bike repair. SITE DESIGN/LAND USE Promote Location-efficient—1 Point The development site is in close proximity to transit service along Arsenal Street and Mount Auburn Street with a good walking and bicycling conditions and will help promote those alternatives. Cross-Site Connectivity—1 Point A pedestrian walkway has been developed to connect to adjacent land uses. ON-SITE EMPLOYEE TRANSPORTATION COORDINATOR—5 POINTS The Proponent will designate a member of the staff as transportation coordinator responsible for disseminating relevant TDM information to the building tenants including posting of TDM information at appropriate locations within the buildings. The Transportation Coordinator will have the following duties: ➢ Create and administer TDM promotions and incentives in coordination with the Watertown TMA including rideshare matching and emergency ride home program; ➢ Create an employee information packet, distributed to all employees of the building, that includes information on transit,bicycling, and walking connections. Can include information on local stores, services, and restaurants as well transportation connections. ➢ Manage preferential parking on the Site; ➢ In order to encourage the use of public transportation,the property management team will make available public transportation schedules which will be posted in a centralized location for the employees. Transit screens/displays will be provided in the building lobby to display real-time transportation information (similar to httl)s://transitscreen.com/). ➢ Serve as point of contact for tenant questions on TDM programs. TDM MEASURES SUMMARY A Comprehensive TDM Plan must achieve a minimum of 14 points based on the Town's point system with the goal of a 20% reduction in SOV use over time. Overall, this TDM plan proposes measures that satisfy the requirement, reaching a total of 14 points. The proposed measures will reduce the overall number of automobile trips in the area and will promote healthy modes of transportation. GA8124 Watertown,MA\Report\6-TDM-85 Walnut TDM Plan.doe 9 WATERTOWN TRANSPORTATION MANAGEMENT ASSOCIATION(TMA) The Proponent agrees to join the Watertown Transportation Management Association (WTMA) or a successor entity, including financial contributions in a proportionate share for both TMA membership and provision of on-going services. TMAs have been established to develop alternative transportation options and sustainable growth solutions to its members. With the recent growth in the Town of Watertown, participation in a local TMA is critical to the effective management of the area transportation system. The proponent will participate in the Watertown TMA, including contributing monies to the TMA on a proportionate basis consistent with other development projects in the area. Services that the TMA may provide include the following, which will be supported by the proponent through their membership, and may include additional fees: ➢ Shuttle Service — the TMA is expected to provide area shuttle service for its members with the goal of providing connection to area transit stops. If WTMA shared shuttle service is available in the area, the Proponent will make the service available to its tenants and employees and pay a proportionate share of the service. The Proponent will not establish its own shuttle service if shared shuttle service is available in the area. ➢ Bicycle and Walk Resources — The TMA will provide local bicycle and walking maps to promote healthy commuter alternatives. In addition, the TMA will sponsor periodic bicycle and safety clinics on-site. ➢ Carpool/Vanpool Matching — The TMA may provide a matching program for employees who wish to rideshare. The TMA may also provide newsletters, commuter surveys, and services as an advocate for transportation programs for its members. If at any time the WTMA ceases operations, the Proponent On-Site Employee Transportation Coordinator will provide Bicycle, Transit and Walking Resources and Car and Vanpool Matching services. GA8124 Watertown,MA\Report\6-TDM-85 Walnut TDM Plan.doe 10 MONITORING AND REPORTING PLAN To ensure compliance with the Town of Watertown Vehicle Trip Reduction Ordinance, as well as utilization of the TDM programs, monitoring and reporting will be conducted throughout the lifetime of the project in accordance with TDM guidelines, including (a) the preparation of a Pre-Occupancy Monitoring Reporting Form, to be approved by DCDP prior to the Certificate of Occupancy, and (b) ongoing monitoring and reporting following occupancy of the building (Post-Occupancy). The Proponent will submit an Annual Report to DCDP with data on commuting mode. Specific requirements for Pre-Occupancy and Post-Occupancy monitoring and reporting are as follows: PRE-OCCUPANCY Prior to the issuance of Certificate of Occupancy,the proponent will facilitate a site inspection by DCDP staff to confirm that all approved physical measures in the project's TDM Plan have been implemented and/or installed. POST-OCCUPANCY AND ESTABLISHMENT OF BASELINE DATA The proponent will monitor traffic volumes at the Project annually and submit a report to DCDP on an annual basis. Within 60 days following full occupancy of the property, the Proponent will collect data in order to establish a baseline for commuting mode, for comparison to future commuting mode data. This effort will include: ➢ Transit/Pedestrian Counts — Proponent or designee will count the number of users of transit, TMA shuttles and pedestrians near the Site driveways. ➢ Bicycle Counts — The number of bicycles in all bicycle parking areas will be recorded twice during the same day as Traffic Counts, or in the case of inclement weather, on another weekday during the same week. Bicycles shall also be counted at site driveways along Walnut Street at the same time as Traffic Counts. ➢ Traffic Counts - Traffic counts at the site driveways along Walnut Street will be conducted on a typical weekday morning between the hours of 7:00 AM and 9:00 AM and on a typical weekday evening between 4:00 PM and 6:00 PM. The traffic counts will be compared to the volumes estimated in the April 2019 Traffic Impact Assessment (TIA) prepared for the project. Adjustment of trip generation to reflect actual Project GA8124 Watertown,MA\Report\6-TDM-85 Walnut TDM Plan.doe I I occupancy at the time of the counts shall be made when comparing to trip projections cited in the TIA. Count periods shall not include holiday and non-school periods. ➢ Parking Counts - A parking accumulation survey (7:00 AM to 9:00 PM on a typical weekday) will be completed to review the project-side parking demand. Count periods shall not include holiday and non-school periods. ➢ Survey - Tenant surveys will be completed on an annual basis to document commuter patterns and travel modes of employees. The first survey will be completed after initial occupancy to establish baseline conditions. Subsequent surveys will be conducted annually,with results reported to DCDP. The TDM program shall be required to have a traffic monitoring program which will commence immediately after issuance of the permanent Certificate of Use/Occupancy for the first new building or phase, and continue on an annual basis for a minimum of five years after the final Certificate of Use/Occupancy for the last building or phase of development on the site. Annual Monitoring data will be compared to the Baseline data and any other subsequent data, and reported to DCDP. If the annual monitoring reports submitted show that the site is or is not consistently meeting the SOV goals of the TDM Program, then the proponent, in consultation with the DCDP, may reduce or increase the duration for which monitoring reports are submitted. The monitoring program report is to be provided to DCDP within 2-months after the completion of the first data collection effort and annually thereafter for the duration of the monitoring program. The SOV goal of the TDM program is reduction of single occupancy vehicle(SOV)trips by 20%over baseline data. The monitoring report will document the traffic volumes associated with the site as occupied at the time that the traffic counts are completed, on and off-site parking, and use of public transportation resources and alternative modes of transportation to single-occupant vehicles. The DCDP will be responsible for making a determination of compliance as to implementation of the TDM measures. If the DCDP determines that the site is not consistently meeting the goals of the TDM Program, DCDP may work with the Petitioner to undertake additional measures, which may include (without limitation)TDM measures not previously taken by the Petitioner to reduce SOV trips.
