Project Narrative The Arsenal Project Arsenal Street Watertown, MA 02472 Prepared for: Boylston Properties 800 Boylston Street, Suite 1390 Boston, MA 02199 and The Wilder Companies 800 Boylston Street, Suite 1300 Boston, MA 02199 Prepared by: RJO'CONNELL & ASSOCIATES, INC. 80 Montvale Ave, Suite 201 Stoneham, MA 02180 In Association with: Prellwitz Chelinski Associates, Inc. 221 Hampshire Street Cambridge, MA 02139 and Carol R. Johnson Associates, Inc. 21 Custom House Street Boston, MA 02110 and R.D. Vanasse & Associates, Inc. 35 New England Business Center Drive Andover, MA 01810 Date: July 11, 2016 Resubmitted: September 13, 2016 THE ARSENAL PROJECT Project Overview After more than 30-years as an enclosed mall, Boylston Properties and The Wilder Companies ("Proponent") are re-envisioning and re-positioning the 23± acres of land that make up the Arsenal Mall. The property was used by the US military until 1968, when the General Services Administration sold approximately 55 acres to The City known as Town of Watertown("Town"). A portion of this land would become the site of the Arsenal Mall in 1983. The Proponent is proposing to redevelop the Mall to create an environment where living, shopping, dining, and entertainment all take place ("Project" or "The Arsenal Project"), with attractive outdoor spaces, inviting shops, dining experiences, entertainment options, and a residential component adding activity and energy to the area. As was common when the Mall was constructed in 1983, the site is comprised of buildings that make up the retail mall, which ring large areas of pavement for parking, with little landscaping or useable open space. The Project entails the removal of buildings, portions of buildings, and the majority of the large parking fields, and replacing them with new building arrangements with a focus on the outdoor pedestrian experience. This is achieved through the introduction of landscape features, streetscape, residential activity, and parking structures. Upon completion, the resulting Project will add approximately 110,000 SF of retail space and 500 residential units spread among 7 buildings, with 5 of them new. 15% of the residential units will be designated affordable. All buildings will be designed and constructed to a LEED silver certifiable level. A defining feature of the proposed project is the introduction of additional bike and pedestrian connections to the adjacent Arsenal Park, the DCR controlled Greenough Boulevard bike path, the Watertown Greenway, and views to the Charles River. These connections are created by removing additions made in 1983 to create the Mall. The result is a regional mixed use development that encourages multi-modal transportation and emphasizes biking and walking. The proposed project's development program is in response to the Town of Watertown's desire for additional large-scale mixed use projects. The Town completed an Economic Development Study in 2011 and a Comprehensive Plan in 2015 that identifies this section of Town, and these parcels specifically, as underutilized. The Study and Plan further recommended that incentives should be put in place to encourage redevelopment c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 1 that includes a mix of uses and higher density. The Town implemented the goals of these two studies through a re-zoning effort, led by the project proponent, for an area of Town that includes the Project Parcels. This re-zoning introduced a new zone- the "Regional Mixed Use District (RMUD)", which was recommended by the Planning Board and approved by the Town Council on March 2, 2016. Historical Context The subject site and surrounding area was formerly established as a depot for the storage,repair and issue of small arms,ordinance and supplies. The Watertown Arsenal is reported to have occupied the maximum extent of property, a total of approximately 130 acres, in the 1940's. In the 1960's the Arsenal property began to undergo a phase down and reduction of property activities. The entire Watertown Arsenal, including the subject site and property to the north, south, east and west of the subject site, was decommissioned and is now identified as a Formerly Used Defense Site(FUDS). Many of the former Arsenal structures were demolished in 1975 to make way for redevelopment of the Arsenal property. Redevelopment began in 1977 with the Arsenal Park,which is located to the south of the subject site and continued through 1987 when the office building now utilized by Harvard Vanguard Medical Associates ("HVMA") was completed. The subject property portion of the Arsenal property was primarily redeveloped for retail use. Most Arsenal buildings were demolished for the retail use, however, some buildings were preserved and renovated including Building 51 and 121 (HVMA), Building 44, 221, and 331 (Arsenal Mall), Building 32 (Arsenal Mall, Golfsmith and Home Depot), and Building 215 (617 Arsenal Street building). A Project Notification Form was compiled for review by the Massachusetts Historical Commission. The PNF identified each of the potentially historic structures on the site and discussed their existing and proposed uses. On July 13, 2016 the Massachusetts Historical Commission determined that The Arsenal Project is unlikely to affect historic and archaeological resources. Existing Conditions The subject property occupies an approximate 23-acre area fronting onto Arsenal Street to the north and generally bounded by residential and commercial properties to the west, Arsenal Park to the south,and Charles W. Greenough Boulevard to the south/southwest. The site is located within what was formerly the Watertown Arsenal. c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 2 An existing commercial property occupied by a Home Depot, that is not part of the subject site, divides the site into a western and eastern portion. The western portion of the site,which is generally identified as 485 Arsenal Street, is occupied by three, one to two-story structures including the Arsenal Mall and two office buildings. The redevelopment of the project site is generally within this portion of the property. Approximately 260,000± GLA of retail and 53,000± GLA of office space is included within this portion, which is made up of the enclosed mall buildings and the Golfsmith building, and the HVMA office buildings. The eastern portion of the site, which is generally identified as 617 Arsenal Street, is occupied by an existing two-story commercial building with an attached parking garage. The building includes 64,000± GLA of retail and office space, which will remain generally unchanged as part of the proposed development plan,at least for the near term. An approximate 100-foot wide section of property located on the southern end of the site connects the western and eastern portions of the site. The proposed development is presently limited to the western portion of the property. Proposed Project - Development Program On March 2, 2016, the Watertown Town Council & Planning Board approved new zoning that changed the zoning for the Mall parcels from a heavy industrial zone to a "Regional Mixed Use District" or RMUD. The RMUD's intent is to create a mix of retail(large&small scale),office and research&development uses to serve the regional market, which is consistent with the Arsenal Project development objectives. The Proponent has created a site plan that works well for the tenants, residents, customers, and community. The proposed project entails taking down the 1980's additions that make up the existing enclosed mall and re-exposing the two original Arsenal buildings. This will open up enough space to create an inviting urban street environment, with opportunities for additional plazas and green space between attractive new buildings. In addition, the existing mall acts as a barrier to the adjoining Arsenal Park and Charles River. The new Arsenal Project will open up the pathway to the park and the Charles River for Watertown residents and visitors. The project entails seven buildings; two existing buildings with historic characteristics and five new buildings. A significant aspect of the project is the proposed demolition of the 1980's additions. The removal of these structures enables vehicular and pedestrian movement to occur more logically and to connect the site visually and physically to the c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 3 Arsenal Park. The five new buildings have been sized and located to enable new pedestrian oriented streets and gathering spaces to be created between them. At grade in most locations, retail uses will be located to activate the public realm. Floors above are mainly residential dwelling units. Two of the buildings will include above ground parking decks, with four of the buildings utilizing below grade parking. Associated with adding connections to the Park and the Charles River,the Proponent is including a multi-use pathway between Greenough Boulevard and the Site. The purpose of the pathway is to provide improved access between the Arsenal Park, the Site, and the River. A portion of this path is located within the 200' riverfront area. In addition, the potential of adding a vehicular connection from the site to Greenough Boulevard is being explored with DCR. This connection would be within the Riverfront Area, but would maintain less than 10% of impact to this area. Careful attention has been paid to the spaces between buildings to consider proportions of width to height, creating comfortable, spacious, yet intimate gathering places. All buildings comply with local setbacks as required by the newly adopted RMUD zoning regulations, and utilize breaks in the forms and massing to soften their visual impact on the surrounding areas. Opening breaks in the fagade at grade enable pedestrians to pass into the public spaces beyond. Plan Details - Specifics The proposed redevelopment project includes the selective demolition of the newer portions of the existing Arsenal Mall buildings, and the construction of five (5)new structures which will be occupied by a combination of parking,residential units, and retail/commercial space. The proposed new buildings include the following (additional detail can be found on the attached Site Plans): •Building B—A six(6) story mixed-use building occupying an approximate 65,000 square-foot area overlying one (1) level of below-grade parking, retail space on the ground floor, three (3) levels of parking within an above ground garage, and residential units on floors 2 thru 6. •Building C—A six(6) story mixed-use building occupying an approximate 30,000 square-foot area overlying one (1) level of below-grade parking, retail space on the ground floor, and residential units on floors 2 thru 6. Building C will share the below-grade parking with Building D. The space separating Buildings C and D will be used as a shared street with useable open spaces (also known as a "woonerf'). Building C will be constructed within an existing parking area. cAusers\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 4 • Building D — A five (5) story mixed-use building occupying an approximate 25,000 square-foot area overlying one(1)level of below-grade parking,retail space on the ground floor, and residential units on floors 2 thru 5. •Building F—A six(6) story mixed use building occupying an approximate 57,000 square-foot area overlying one (1) level of below-grade parking, retail space on the ground floor,three(3)levels of above ground parking,and residential units on floors 5 and 8. Building F will be constructed within the area of a portion of the existing mall which will be demolished. • Building G —A twelve (12) story residential building occupying an approximate 16,000 square-foot plan area. Building G will be located to the south of the existing buildings. The proposed development also include the following changes to the existing mall buildings to remain: •Building A-Renovations to the existing western half of the southern Arsenal Mall building to accommodate retail/entertainment uses. • Building E — Renovations to the existing northern building which fronts onto Arsenal Street for retail uses. Also included is constructing an addition onto a portion of the structure, to create a second level for retail/entertainment uses. In addition to these buildings, major site upgrades are included, adding substantial stormwater management facilities, utility upgrades, and landscape/open spaces for public use. Two (2) subsurface stormwater(SS)infiltration systems are proposed at the site to substantially mitigate stormwater impacts to the Charles River that currently exist. Greater than 20%of the site has been dedicated to open space. The open space consists of green space as well as enlivened public sidewalks and plazas. These areas will provide seating and dining areas, open areas to meet and entertain, and provides access to proposed retail, housing, and entertainment options, as well as adjacent parklands. Enhanced landscaping will be provided to establish comfortable streetscape conditions while also providing acceptable screening of necessary utilities and service areas. A variety of deciduous street trees will be used throughout the site and in the parking areas, while a mix of deciduous and evergreen trees will be used along buffered property edges. cAusers\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 5 When completed, the total project will consist of approximately 485,000 SF of retail/office (a net increase of approximately 110,000 SF of GLA), and approximately 500 new residential units. Interior Common Areas will account for an additional 35,000 SF.

Is the subject site an appropriate location for such use, structure, and/or condition? The Arsenal Project is located within the newly adopted Regional Mixed Use District, which outlined a specific geographic location that included the subject parcels. The proposed development is in keeping with the intent and purpose of the adopted zoning district as outlined in the project description and accompanying materials. 2. Will the proposed use/structures adversely affect the neighborhood? The Arsenal Project will enhance the neighborhood by replacing existing empty parking lots with streetscape, open space, buildings and inviting retail destinations. The proposed design has followed the intent of the Design Guidelines, connections to adjacent parks and bike paths will be created, and significant upgrades to the infrastructure and stormwater management system will all contribute positively to the neighborhood. 3. Is there potential for nuisance or serious hazards to vehicle or pedestrians? The Arsenal Project has incorporated significant pedestrian, bike, and vehicle accommodations within the site plan. A traffic demand management plan and roadway improvements have been incorporated into the traffic mitigation measures, which will minimize impacts to adjacent streets. 4. Will adequate and appropriate facilities be provided for the proper operation of the proposed use? As shown on the attached materials, the proposed The Arsenal Project includes accommodations for parking, stormwater management, water/sewer use, and public utilities. The design takes into consideration applicable life-safety components, building codes and requirements, and public safety access. c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 7 Project Narrative per Section 9.03 of the Site Plan Review Submission Guidelines 1. Landscape The project landscape provides an increase of open space to what is currently a substantially impervious site condition. Multiple open space areas of various sizes will be provided, including a large green space providing potential connectivity to the existing Arsenal Park. Adequate landscaping will be provided to establish comfortable streetscape conditions while also providing acceptable screening of necessary utilities and service areas. A variety of deciduous street trees will be used throughout the site and in the parking areas, while a mix of deciduous and evergreen trees will be used along buffered property edges. 2. Relation of Buildinas to Environment The project entails seven buildings; two existing buildings with historic characteristics and five new buildings. A significant aspect of the project is the proposed demolition of a 1980's addition. The removal of this structure enables vehicular and pedestrian movement to occur more logically and to connect the site visually and physically to the Arsenal Park. The five new buildings have been sized and located to enable new pedestrian oriented streets and gathering spaces to be created between them.At grade in most locations,retail uses will be located to activate the public realm. Floors above are mainly residential dwelling units. Two of the buildings will include above ground parking decks, while four of the buildings will include underground parking. Careful attention has been paid to the spaces between buildings to consider proportions of width to height, creating comfortable, spacious, yet intimate gathering places. All buildings comply with setbacks as required by the RMUD zoning regulations, and utilize breaks in the forms and massing to soften their visual impact on the surrounding areas. Opening breaks in the facade at grade enable pedestrians to pass through to the public spaces beyond. 3. Open Space Greater than 20% of the site has been dedicated to open space. As noted in the Landscape Narrative,the open space consists of green space as well as enlivened public sidewalks and plazas. These areas will provide seating and dining areas, open areas to meet and entertain, and provides access to proposed retail, housing, and entertainment spaces as well as adjacent parklands. The design planning of all open spaces will include dimensions for movement as well as gathering. c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 8 Refer to Open Space Exhibit and Interior Open Space Exhibit on Drawing C-10 of the Site Plan Set. 4. Circulation The project design incorporates many principles of smart growth by providing a concentrated mix of uses, sustainable transportation choices, shared parking and multiple site connections for convenient circulation. Within the area surrounding the site, there are multiple choices of recreation, work, shopping and housing. Live — work— play in one area allows for shared trips reducing the impacts on the roadway infrastructure. With respect to site circulation, site access and egress is provided via two signalized intersections with Arsenal Street,a right-in/right-out only driveway and an entrance only driveway. This allows for traffic to disperse entering and exiting the site. In addition, through consultation with the Department of Conservation and Recreation, an evaluation of a secondary means of access and egress to Greenough Boulevard is being completed. This rear driveway will accommodate vehicles, bicycles and pedestrians and will reduce traffic on Arsenal Street, but will remain a secondary driveway. The intersection is expected to remain unsignalized with a turn lane expected on Greenough Boulevard eastbound entering the project. Parking is provided in a mix of surface lots, subsurface parking areas, and parking garages. Due to the multiple uses, on-site parking supply will be shared reducing the overall need for parking. For example, residential and some of the entertainment uses peak during the evening hours,while other retail and restaurant uses peak during the day or earlier in the evening allowing the uses to "share"parking. The parking areas will also have compact car spaces, carpool spaces, electric car charging stations and car-share spaces. Refer to the attached Shared Parking Study by Walker Parking Consultants for details. Non-auto modes of travel will be emphasized with the project design to encourage bicycle, pedestrian and transit usage. The Watertown Greenway is a multi-use path and provides connections to recreational and shopping opportunities in the area. The Watertown Greenway was completed in 2010 and traverses the area between Arsenal Street and Arlington Street. A bicycle connection is planned on-site to connect the Arsenal Park to the Watertown Greenway. In addition, Arsenal Street is designated as a bicycle route with"share the road" signs along the street. The site design will encourage pedestrian travel throughout the site with multiple sitting areas, pocket parks and connections to Arsenal Street. Major site design elements include connections to the Arsenal Park which connect the site to the recreation uses and pedestrian ways. A pedestrian connector is also planned from the Arsenal Project to Greenough Boulevard. Convenient MBTA bus service is provided along Arsenal Street with multiple bus stops located along the frontages. The Arsenal Project will encourage transit usage by providing MBTA pass c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 9 sales on-site. Maps and promotional material will also be provided on-site at a convenient centralized location. The Arsenal Project will also be a founding member of the, to be established, Watertown Transportation Management Association (TMA). Services provided by the TMA will include shuttle service, Emergency Ride Home Program, ride matching program, carpool vanpool matching, bicycle/walk support resources, bicycle awareness and repair days and a newsletter to members encouraging alternative modes of travel. The area is also under significant study by the Town of Watertown, MassDOT, and the MBTA and the Arsenal Project has been in attendance at the study meetings and has shared relevant information with respect to the project and is supportive of the study efforts. Refer to the Fire Truck Turning Exhibit and the Truck Turning Exhibit on Drawing C-11 of the Site Plan Set. 5. Surface Water Drainage The proposed stormwater management system for the redevelopment includes measures for collecting, controlling, and treating stormwater runoff from the site. The drainage improvements proposed herein will reduce stormwater runoff peak flow rates and volumes leaving the site, increase groundwater recharge, and improve storm runoff water quality. The proposed measures under the redeveloped conditions comply with the Massachusetts Stormwater Handbook and the Town of Watertown's Requirements for Stormwater Management and Erosion Control to the maximum extent practicable, and represent a significant improvement over pre-redevelopment conditions. The proposed modifications include the following improvements: 1. Stormwater Management System Design The proposed stormwater management system has been designed to significantly reduce peak discharge rates and volumes at three Points of Analysis (POA). Under post-redevelopment conditions, two new subsurface infiltration systems will be initially constructed, and a third subsurface infiltration system will be constructed on the Harvard Vanguard Medical Associates (HVMA) parcel in the future. These subsurface infiltration systems will result in reduced peak rates and volumes of runoff leaving the site at the Points of Analysis under post-redevelopment conditions compared to pre-redevelopment conditions as summarized below. Point of Analvsis 1 (POA-1)—30-inch Drain Line Subsurface Infiltration System 1 (SSI-1),which is located at the north side of the site, will discharge to the Town of Watertown's existing 30-inch drain line in Arsenal cAusers\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 10 Street. SSI-1 will initially provide an 83%reduction of the peak flow rate, and a 9 1% reduction of the total runoff volume for the 24-hour, 100-year rainfall rate from the Extreme Precipitation in New York and New England developed by the Northeast Regional Climate Center at Cornell University, often referred to as the Cornell rate. After construction of the new subsurface infiltration system on the HVMA parcel, SSI-1 will provide a 95%reduction of the peak flow rate, and a 97%reduction of the total runoff volume for the 24-hour, 100-year, Cornell rainfall accumulation. Point of Analvsis 2 (POA-2)— 15-inch Drain Line The area and runoff curve number of the watershed that discharges runoff to Point of Analysis 2 (POA-2), which is located on the south side of the site, will be reduced under post-redevelopment conditions. These reductions will initially provide a 72% reduction of the peak flow rate, and a 73%reduction of the total runoff volume for the 24-hour, 100-year, Cornell rainfall accumulation. After construction of the new subsurface infiltration system on the HVMA parcel, all of the runoff from the watershed will discharge to either SSI-1 or the new HVMA system. Ultimately, no runoff will be discharged from the site at POA-2,resulting in a 100%reduction in both the peak flow rate and the total runoff volume for the 24-hour, 100-year, Cornell rainfall accumulation. Point of Analvsis 3 (POA-3)—24-inch and 18-inch Drain Lines Subsurface Infiltration System 2 (SSI-2), located at the southeast portion of the site, will discharge to the Massachusetts Department of Conservation and Recreation (DCR) drainage system in Greenough Boulevard. SSI-2 has been designed to detain and infiltrate approximately 88% of the volume for the 24-hour, 2-year, Cornell rainfall accumulation of 3.2 inches. This system exceeds the 1-inch water quality volume requirement,and will significantly reduce post-redevelopment peak flow rates and volumes compared to pre-redevelopment rates and volumes at POA-3. 2. Water Quality The water quality of the site will be greatly improved under post-redevelopment conditions. Stormwater best management practices(BMPs)to be implemented on-site include: street sweeping, catch basins with deep sumps and hooded outlets, CDS oil/particle separators, and subsurface infiltration systems. The average annual post- construction load of total suspended solids (TSS) removed by this BMP treatment train, which applies to Points of Analysis 1 and 3, is 89%. Based upon the P8 Water cAusers\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 11 Quality Model performed for the Final Phosphorus Total Maximum Dailv Load (TMDL) Report for the Charles River Basin, infiltration practices sized to store and infiltrate 1-inch of runoff from impervious cover captures at least 80% of the phosphorus in the runoff. Infiltration practices designed to this standard significantly exceed the 65% requirement by which Watertown is required to reduce their annual phosphorus loading to the Charles River. On this site, more than 95% of the phosphorus loading in the runoff will be captured at all three Points of Analysis,where infiltration practices have been sized to store and infiltrate at least 2.8 inches. Most of the parking will be provided in subsurface and above-ground garages, which will be protected from exposure to rain, snow, snowmelt,and stormwater runoff, significantly reducing the potential pollutant load in stormwater runoff on the site. 3. Operation and Maintenance Plan An Operation and Maintenance Plan (O&M) is provided as part of the Stormwater Report to ensure that the proposed improvements and treatment measures are effective after the completion of construction activities. 6. Utility Service The existing Arsenal Mall, the adjacent HVMA building and the adjacent Arsenal Condominium building, are served by existing utilities located in Arsenal Street to the north of the site and Greenough Boulevard to the south. Utility services to the HVMA building and the Arsenal Condominium building will remain unchanged under the proposed development program. Two existing, separate 10-inch water mains loop the Home Depot and Arsenal Mall sites. The Arsenal Mall loop will be replaced with a new 10-inch loop with two new connections off the 12- inch water main in Arsenal Street. The loop will be installed in the main drive aisles and will supply fire protection and domestic water to the proposed buildings. Existing buildings will continue to be supplied by existing service lines. The loop will be sectionalized with zone control values and interconnected with the Home Depot loop. New hydrants will be installed throughout the site to provide adequate fire protection coverage. Fire flow tests have been conducted on each of the existing loops to quantify existing fire flows. The tests indicated sufficient flow and pressure in both loops to handle the projects demands and resulted in fire hydrants classified as AA(1500 gpm or greater capacity at 20 psi residual pressure). New Eight(8) inch polyvinyl chloride(PVC) sewer mains will be installed in the access drives on the site to service proposed buildings. Sewers will flow by gravity in a northerly direction and c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 12 connect to the 12-inch sewer in Arsenal Street. Sewage from Existing Building A,part of proposed Building F and proposed building G will flow by gravity in an easterly direction into the existing sewer along the east side of the site adjacent to the Home Depot property and discharge into the 15-inch sewer in Greenough Boulevard. Building plumbing has not been finalized, but there is sufficient capacity in the 12-inch sewer in Arsenal Street to accommodate all sewage from the proposed project. Separate waste lines will be provided for all restaurants and food handling facilities and exterior grease tanks will be installed on kitchen waste lines to intercept and separate grease, minimizing the potential for impacting sanitary sewers. Runoff from rain and snow melt from cars parked in the proposed above and below ground parking garages, not exposed to the environment,will discharge to the sanitary sewer in accordance with the Massachusetts Plumbing Code. Oil/water separators will be provided for pretreatment of this wastewater prior to discharging to the sanitary sewer in accordance with State and MWRA regulations. A new underground primary electric duct bank system will be installed throughout the site to service each building of the Project. The duct bank system will consist of concrete encased conduits, manholes, transformers and switchgear as necessary based upon Eversource requirements. Service will be provided from the existing underground duct banks and have sufficient capacity to meet the projects demands. Trash and recycling will be disposed of in proposed dumpsters located at the southwest corner of Building A,the southwest corner of Building B,the east side of Buildings C and D,the south sides of Buildings E and F, and the north side of Building G. The dumpster areas will be located within a screened enclosure, and managed by a private waste management contractor. 7. Environmental Sustainabilitv The proposed Arsenal Mall Redevelopment project in Watertown, MA will be sustainably designed, constructed and operated and will seek to limit negative effects on the local and global environment and existing municipal infrastructure. The project is located in an existing urban environment within close proximity to many local services and easy-to-access public transportation. These factors can help to reduce the number of vehicular miles travelled in Watertown and the surrounding communities which contributes to the location desirability and helps minimize car travel in the neighborhood and adjacent areas. As indicated in Section 5, a comprehensive stormwater management system will be designed and implemented for the development site. Site stormwater runoff will be directed to catch basins, treated, and discharged to an extensive recharge system. c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 13 A significant amount of vegetated and pedestrian oriented open space will be provided to allow for permeability,biodiversity,and walkability.Additionally,native and adaptive plant species will be specified and planted to reduce the demand for potable water for irrigation needs. Heat island effect will be minimized through the use of landscaping, light colored pedestrian walkways/sidewalks, light colored roof materials and centralized parking garages. The new construction projects will incorporate sustainable design measures including high performance building envelopes, and high efficiency mechanical,plumbing, and lighting systems that will enable the buildings to meet or exceed local energy code requirements. The owner plans to engage a third party commissioning agent to review the design documents, mechanical equipment submittals, systems installations and to ensure the owner's project requirements are met. During construction, an Erosion and Sedimentation Control Plan will be implemented to prevent the loss of soil and sedimentation into the nearby Charles River and the municipal stormwater system, and to prevent pollution of the air with dust and particulate matter. Additionally, the contractor will divert a minimum of 75% of the construction and demolition waste from area landfills; it will be delivered to local sorting facilities for recycling. The two existing historic arsenal buildings shall remain with minimal modifications. The design team will specify materials that have recycled content and are regionally obtainable to the extent possible. The interior environments will include low emitting finish selections to limit negative effects on the indoor environment and human health. The residential units will have operable windows and ample access to daylight and views. Several buildings within this development may be registered with the United States Green Building Council, (USGBC), and some may pursue Leadership in Energy and Environmental Design, (LEED) certification under version 3 of either the New Construction (LEED-NC) or Core and Shell (CS)rating system; dependent on the building use type. Retail buildings will be categorized under LEED-CS and buildings containing residences will be classified as LEED NC. Regardless of whether the buildings pursue LEED certification,the new buildings will be designed and constructed to meet the minimum requirements, including meeting all of the prerequisite requirements, to achieve the equivalency of LEED Silver certification. Refer to attached draft LEED checklist. The project will use the applicable LEED rating systems as a validation tool to check our sustainable performance but, in general, will not base design decisions strictly on achieving a specific level of LEED certification. While the design team seeks to achieve the equivalency of LEED Silver certification (50 credit points); our approach is not one of "point chasing" to c:\users\jeffrey\google drive\company shared\projects\arsenal mall(bp watertown office-retail llc)\permitting\mpsp\narrative-final-9-12-16.docx 14 maximize a LEED score. Rather we seek to design and construct a development with energy efficient sustainable buildings which collectively minimize the impact of the collective buildings on the environment and long term operating costs. 8. Screeninq Adequate and effective screening of onsite utilities will be provided by a mix of evergreen and deciduous planting as well as architectural screens and fences. The plantings will be placed on low, mounded, graded areas where space allows. Attractive screen fences will be in keeping with the proposed site architecture 9. Safety Building evacuation shall be designed to meet code for egress at all levels. The site is accessible by emergency vehicles from the three entrances along Arsenal Street and the access through the adjacent Home Depot lot. Fire truck access is provided along Building A to the west by the loading area, to the south using existing protocol for the rear of the existing Mall, to the east by the plaza area, and to the north using the existing protocol for the exiting Mall building. Access is provided around Building's B, C and D by interior access ways to the east, west and south and to the north by Arsenal Street, and to Building E by Arsenal Street to the north, a parking area to the west, and an interior access way to the south. Building F will have fire truck access to the north, south, and east by interior access ways, and to the west by the plaza area, while Building G has access from the north and east by interior access ways, and to the south by Greenough Boulevard. Fire truck turning movements can be found in the Fire Truck Exhibit on Drawing C-11 of the Site Plan Set. 10. Desi_an The project will be designed to protect abutting properties from detrimental site characteristics resulting from the proposed use by implementing a stormwater management system which will reduce stormwater runoff and potential flooding and water pollutants. Trash will be disposed of in closed dumpsters within a screened enclosure which will help mitigate potential odors and negative visual impacts.A mix of deciduous and evergreen trees will be used along buffered property edges. Construction related impacts, such as dust and erosion, will be mitigated through the implementation of a Stormwater Pollution Prevention Plan. Mechanical systems will be high efficiency designed to operate at 90-95% efficiency and to minimize noise levels. Garage lighting will be provided by LED fixtures with both Photocell and Occupancy Sensor control.

As part of the MPSP approval for a mixed-use development, the developer is seeking a reduction in the parking requirements as outlined in Section 5.18(h)(4)of the Zoning Code. The developer has completed a parking analysis, as required by the code. As indicated in the attached parking tables, RJOC has calculated the parking requirements based on Zoning Article VI, Automotive and Bicycle Parking Requirements. This was completed by separating each of the project components into their requisite category based upon the Zoning Code, and calculating the total spaces required,without taking any peaking demands into consideration. Per this calculation, the overall parking required is 2,123 spaces, as shown on the attached table. Walker Parking Consultants was contracted by the developer to complete a Shared Parking Analysis as permitted under the MPSP for a mixed use development in the Regional Mixed Use District. Their summary memo revised September 12, 2016, and attached, shows that once the peak use times and other factors are taken into consideration,the proposed project parking demand will be in December, with a peak of 1,753 on a weekday and 1,431 on weekends. Therefore,based on the Shared Parking Analysis, a reduction of 17.4% in the parking requirement is permissible. The current plans show the overall parking provided is 1,759 spaces, including 163 surface parking spaces (see attached Parking and Traffic Control Plans C-4A and C-4B). The parking provided exceeds the parking necessary for both the peak weekday and weekend demand, based on the Shared Parking Analysis.

Walker made the following observations: • The heaviest concentration of parked vehicles was in the lot due south of the Home Depot store and the lot east of the Harvard Vanguard Medical Building (HVMB). • The lot signed for the HVMB appeared underutilized. • The northwest corner of the Home Depot lot appeared to be occupied by vehicles from the office building east of the access drive dividing the properties. • Based on these observations, the current parking supply appears adequate to service the existing land-uses. Additionally, Walker's observation of One Arsenal (52,600 of office space and 10,600 of retail) determined the available parking supply is too far from the restaurants and retail to be considered part of the shared uses study. To verify the existing parking supply, a parking space inventory was completed. The parking spaces for the Home Depot Lot and 1 Arsenal were not included.

SHARED PARKING METHODOLOGY Shared parking is defined as parking spaces that can be used to serve two or more individual land-uses without conflict or encroachment. The ability to share parking spaces is the result of two conditions: • Variations in the accumulation of vehicles by hour, day, and/or season for the individual land-uses, and • Relationships among the land-uses that result in customers visiting multiple land-uses on the same auto trip. As an example of the first condition, office buildings require parking spaces during daytime hours on weekdays, while restaurants and entertainment venues have peak parking demands during the evening and weekends. In addition, the interplay of land-uses in a mixed-use environment also produces a reduction in overall parking demand. For example, a substantial percentage of patrons at one business (such as a restaurant) may be employees of another business (such as nearby offices). This is referred to as the effects of the "captive market." These patrons are already parking on-site or in a nearby parking facility for the day and therefore contribute only once to the number of peak hour vehicles present in the system. As a result of these two variables, the parking demand ratio for individual land-uses should be factored downward in proportion to the captive market support, and to reflect the variations in hourly accumulation of demand. Walker's SPM is designed to project the parking needs of a mixed-use development from 6:00 a.m. to 12:00 midnight on a typical weekday and weekend day for every month of the year. Our model is based on research data obtained from organizations such as Urban Land Institute, Institute of Traffic Engineers, International Council of Shopping Centers, and Walker's own internal research. The SPM developed for this assignment projects the approximate number of spaces needed to provide adequate parking on weekdays and weekend days during peak conditions at an 85th percentile level of performance. The following flow chart describes the logical progression of a basic shared parking analysis. MEMORANDUM v WALKER THE ARSENAL PROJECT PARKING CONSULTANTS PAGE 5 Figure 3: Shared Parking Analysis Methodology Standard Parking Adjust for captive Site specific ratios generation ratios land use of each use ratios& driving ratio (spaces/ 1,000 GLA = design parking sq ft of each use) _ site-specific ratio demand for each use Separate into visitor and employee components 1 Adjust for Calculate Determine design month, day of accumulation of days/times/months week& time of parked cars on for employees and typical days in day each month visitors Compare to parking availablity on site Recommended Parking and in area Plan Source: Adapted from Transportation Planning Handbook, ITE, 1999 Base parking demand ratios have been developed by land-use category for both typical weekday and Saturday/Sunday usage. These ratios are adjusted as appropriate for each specific development by factors including modal split and non-captive ratios. Modal split (or driving ratio) reduces the overall parking demand for patrons arriving via mass transit, walking, or riding a bike. When these adjustments are applied to the base ratios and used with the client- provided program data, the result is the peak parking demand. BASE PARKING DEMAND Base parking demand ratios, as found in the ULI SPM and in some cases refined through additional research by Walker, are used as a starting point in the analysis. Based on research on the parking generation rates for free-standing developments, these industry standards are later adjusted to reflect site-specific conditions. Table 3 shows the base ratios for residents, visitors and employees for weekdays and weekends. The following adjustments were made to the SPM; • The dining land-uses demand was calculated using the Watertown zoning requirements. • Residential demand was also programmed with Watertown zoning requirements.

Watertown Zoning Code Source:Walker Parking Consultants DRIVE RATIOS Drive ratio adjustments are applied to the model and reflect the use of transportation modes other than the single-occupancy automobile. These include walking (from home), taxi, bus, ride sharing, biking, and work from home. The following table displays the U.S. Census Bureau's 2009 and 2014 American Community Survey "Journey to Work" statistics for Watertown (Table 4). The points of note include the following; 1. The drive ratio remained constant at 75% between 2009 and 2014. In 2009 65% drove alone and 10% carpooled, while in 2014 67% drove alone and 8% carpooled 2. Between 2009 and 2014, 15% of workers in the area utilize public transportation. According to the Massachusetts Bay Transportation Authority bus schedule, the site would be within walking distance of four to six bus stops. Walker has found access to cost effective public transportation generally works to reduce service employee drive ratios.

In the shared parking analysis, the term "captive market" reflects the adjustment of parking needs and vehicular trip generation rates due to the interaction among uses in an area. Traditionally, the non-captive adjustment is used to fine-tune the parking needs of restaurants and retail patronized by employees of adjacent office buildings, or other persons already counted as being parked for the day. Walker, in designing a shared use analysis, uses the inverse or non-captive ratio, which is the percentage of parkers who are not already counted as being parked. There is usually a primary land-use, in this case the residential and office space, which account for the longest parking durations of a vehicle. Table 7 details the weekday and weekend non-captive factors used in this analysis.

This can have a significant effect on demand at a mixed-use development. By example, a 10,000 sf retail store has a peak demand of about 36 spaces on a weekday and 40 spaces on a weekend day during the peak hour at 1 1:00 AM; while the same store is unlikely to project any parking demand at 1 1:00 PM in the evening. The shared parking demand model evaluates parking demand for each land-use from 6:00 a.m. to midnight on weekdays and weekends for every month of the year. The SPM concludes peak weekday parking demand occurs around 1 :00 p.m. when the medical offices, retail, and fast food components are at or near their peak demand. Table 8 shows the major land-uses and their projected hourly occupancy demands.

O'Connell &Associates, Inc. conducted two flow tests for the proposed development at The Arsenal Mall, 485 Arsenal St, Watertown, MA on the evening of June 16, 2016. For test#1, the flow hydrant was located in a landscaped parking island north of the existing building, in the northwest portion of the site, at approximate elevation 28. The gauge hydrant was located near the drive aisle connecting the two existing parking lots, at an approximate elevation of 36. A 1,375 gallon per minute (gpm) flow rate was observed with a 4 pounds per square inch(psi) residual drop at the gauge hydrant. The static pressure was 102 psi and the residual pressure was 98 psi. Flow calculations for test#1 result in a 7,025 gpm flow rate at 20 psi residual pressure. For test#2, the flow hydrant was located in the grass south of the existing Home Depot parking lot at approximate elevation 27. The gauge hydrant was located in a landscaped parking island south of the Golfsmith store entrance, at an approximate elevation of 27. A 1,450 gpm flow rate was observed with an 8 psi residual drop at the gauge hydrant. The static pressure was 103 psi and the residual pressure was 95 psi. Flow calculations for test#2 result in a 5,130 gpm flow rate at 20 psi residual pressure.

Town Engineer 124 Orchard Street Watertown,MA 02472 Regarding: The Arsenal Project(TAP) Wastewater Flow Generation and Sewer Capacity Analysis Dear Mr. Shuman: RJ O'Connell&Associates, Inc., on behalf of Boylston Properties,performed a wastewater flow generation and sewer capacity analysis to determine the projected additional flow and capacity impacts that to the Town of Watertown's sanitary sewer system following the full build-out of the Arsenal Project (TAP). Wastewater Flow Generation The wastewater flow generation estimate was based on flows developed by Stantec Planning and Landscape Architecture,P.C. for the Athena Arsenal project. Stantec performed a water consumption analysis between September 2014 and December 2015 in which water consumption was directly measured by individual water meters on water lines serving each existing office space and restaurant on their project site. Water consumption was converted to a wastewater flow rate of gallons per day and pro- rated based on square footage to determine a gallons per day per square foot sewage flow generation rate. The analysis resulted in wastewater flow rates approximately half or 50%of the rates established by Massachusetts Department of Environmental Protection Title V.This difference in rates is due to the fact that Title V rates are intended for estimating a maximum daily wastewater flow for sizing on-site sewage disposal(septic) systems and are typically twice or 200%of the actual daily wastewater flow generated. In addition,the proposed TAP project intends to utilize water efficient plumbing fixtures throughout the proposed redevelopment which should further reduce water usage and wastewater generation. Therefore, in estimating the wastewater flow from the proposed TAP project, 50%of the flow rates given in Title V were used. Table 1 (below)is a summary of the wastewater generation estimate.

Sewer Capacity Analvsis Sewer flow metering was conducted on the Town's sewer main located in Arsenal Street and Greenough Boulevard between May 9, 2016 and June 6, 2016 by Flow Assessment Services. Flow metering data for each meter is provided in Appendix A. Five off site metering locations were chosen to measure sewer flow upstream of The Arsenal Project(TAP) site and downstream of all known connections from the Project. The meter numbers and their locations are described below and are shown on the attached figure EX-1, Sewer Meter Exhibit. Sewer Flow Meter Location Number 1 Arsenal Street at intersection with School Street 2 Arsenal Street at intersection with access drive to Target 3 Arsenal Street at intersection with Arlington Street 3A Arsenal Street at intersection with Coolidge Avenue 5 Greenough Boulevard,upstream and east of the MWRA siphon 6 Greenough Boulevard, upstream and west of the MWRA siphon Since no additional daily flow from the Project is proposed to be discharged to the sewer monitored by Sewer Flow Meter 1, sewer flow capacity and peak flow depth were not determined at this location. The sewer flow capacity of 1,620,000 gpd as estimated by Stantec of the 15-inch sewer in Greenough Boulevard, west of the MWRA siphon, was used to determine the peak flow depth in that sewer for the peak proposed flow rate. A meter was not installed at Location 3A, at the upstream end of the 24-inch sewer in Arsenal Street however, the capacity of this sewer was conservatively estimated using the minimum allowable slope of 0.0008 ft/ft for a 24-inch sewer and the depth of flow in the sewer was determined using the peak existing daily flow rate at Meter Location 5. Building plumbing has not yet been finalized. It was assumed that approximately one third of the estimated wastewater from the proposed project will discharge to the 15-inch sewer in Greenough Boulevard through the existing connection from the site. However, there is sufficient capacity in the 12-inch sewer in Arsenal Street to accommodate all sewage flow from the proposed project A summary of the observed average and peak flow rates,peak flow depth, and estimated full flow and half full flow capacity at each meter location, is shown below.

Please refer to Appendix B for the peak flow depths and sewer capacity calculations. The results of the analysis suggest that the municipal sewer system in Arsenal Street and Greenough Boulevard have adequate capacity to convey both the existing and projected additional flows from The Arsenal Project.
