ZBA-2014-27" Page 2 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report II. DESCRIPTION A. Site Characteristics The site is 3.43 acres (149,186 s.f.) and is zoned mostly Industrial-2 (1-2)with two small areas zoned as Two-Family (T), one of which is identified as a separate lot (7,552 s.f.). The dividing line between the two zoning Districts is shown on the Site Layout Plan, C-1 and follows the northerly property boundary of the three houses that abut the former GE Ionics property. The site contains a single, L-shaped 3-story building with a 2-story brick warehouse addition to the rear with a total gross square footage of 133,621 and a footprint of 47,200 s.f. The main building on the site (not including sheds, etc.) dates from 1945, and has a brick veneer and a flat roof.The project site is largely paved or otherwise impervious. The building is currently non-conforming to Watertown's Zoning Ordinance for the Front Yard setback where 16 feet exists and 20 feet is required and parking where approximately 200 formal spaces are provided and 350 are required. B. Surroundinje Land Use The project site is located off Grove Street, with the proposed Watertown-Cambridge Greenway and Multi-Use Path located to the northwest, Crawford Street to the south,the Atrium School as the immediate abutter to the east. Surrounding streets include Coolidge Hill Road, Arlington Street, Nichols Avenue and Mount Auburn Street. Development in the area includes the Atrium School next door, Newlyweds Foods, and the greenhouses for Mount Auburn Cemetery along the opposite side of Grove Street,with Tufts Healthcare taking up the corner of Grove and Mount Auburn Streets. In addition to these larger buildings, there are single and two-family homes along Crawford Street as well as a mix of commercial and industrial uses along Grove Street. C. Nature of the Request The proposed project involves the demolition of a 2-story 8,270 square foot brick warehouse at the southwesterly rear area of the main building to be replaced with a larger(approximately 130'x215') 36 foot tall 3-story, 4-level open parking garage with 290 parking spaces, along with new landscaping, regrading with 59 surface parking spaces (reduced from 200+/-), and installation of a stormwater management system. The project will also renovate the remainder of the existing building(Building Permit only) that includes facade updates, energy efficiency upgrades (including a proposed rooftop photovoltaic solar system),the creation of a new entrance, interior fit-out, and accessibility improvements. Open space on the lot will also become conforming with 6.9% under existing conditions (10% required) and 26.8%open space under proposed conditions. The parking spaces will exceed the required minimum (311), increasing from 200+ under existing conditions to 349 with the proposed development.

ANALYSIS AND FINDINGS A. Plan Consistencv Met:The proposed development is consistent with the Town's adopted planning documents. 1. Watertown Growth Management Plan, 12/01/1988 • Recognition that future development will be almost exclusively"redevelopment" • Continue to designate certain industrial areas for continued industrial use • Maintain an industrial and commercial base for employment and fiscal purposes • Proposed new zoning map retains 1-2 designation: Designated as those areas in Watertown where future regionally oriented industrial/commercial development is most appropriate The project is consistent with these goals; in that the project is a redevelopment of an existing industrial building in an area preserved for industrial/office use. The building has been vacant and is an important aspect of economic revitalization of this industrial corridor and maintaining a balanced tax base for the community. 2. Watertown Community Development Plan,07/2004 • Encourage a range of transportation options • Actively promote walking and bicycling by providing paths, sidewalks, bicycle parking, and improving the streetscape as well as traffic calming measures The project supports these goals. The redevelopment of the GE Ionics building will include improvements to the streetscape, site landscaping and provision of bicycle parking in the proposed garage.The site is adjacent to the Watertown-Cambridge Greenway and will allow for employee access to the multi-use path. 3. Strategic Framework for Economic Development,08/02/2011 • Focused on the Coolidge Hill area as one of five focus areas • Identified this as an ideal area for small to mid-sized companies • Cluster of businesses:Tufts Health Plan, WiTricity, Boston Biomedical(closed-Tufts expansion) • Reuse of GE Ionics building will restore employment activity in the area and will complement the [former] Boston Biomedical Institute (Tufts) across the street • Address concerns about contamination on some properties The project supports these goals through the redevelopment of the GE Ionics building. The proposed project has the potential for one larger or multiple occupants in the renovated building in a key location for a strong economic cluster situated between Coolidge Square and the Arsenal Corridor. The Petitioner will also address onsite contamination and substantially improve stormwater. 4. Draft Comprehensive Plan, In Progress Although not yet adopted,the draft Comprehensive Plan's Economic Development section, Goal 1(B) recommends that Watertown "[e]ncourage the provision of flexible, affordable, and right-sized office Page 5 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report space for small, growing and mid-sized firms, and provide expedited permitting incentives that encourage the inclusion of small-scale,flexible incubator space as a potential amenity."The Comprehensive Plan also seeks to find ways to cleanup/remediate contaminated sites,to promote their reuse and return to the tax base. The proposed redevelopment is in keeping with these goals. The redevelopment of the GE Ionics building into a location for multiple occupants meets Goal 1(B) and the Petitioner will address any onsite contamination as well as containing substantially more stormwater onsite. B. Special Permit with Site Plan Review §5.01(3)(a)(2): New construction greater than 4,000 s.f.; and §5.04 and 5.05(d): Side Yard Setbacks Projects must meet the four conditions of approval for a Special Permit set forth in §9.05(b), of the WZO. In addition,the project is subject to the review procedures under§9.03 Site Plan Review of the WZO, in which the ten criteria listed in §9.03 (c) must be evaluated. Special Permit Criteria§9.05(b) 1. The specific site is an appropriate location for such a use, structure,or condition. Conditionally Met:The proposed redevelopment of the former GE Ionics site is in keeping with Watertown's prior plans and the current draft Comprehensive Plan, as well as the 2011 Strategic Framework for Economic Development. The redevelopment of the GE Ionics site as proposed includes improvements to the streetscape and site design, as well supporting a business cluster, and restores employment activity to the area. The proposed redevelopment also addresses the existing onsite contamination and lack of stormwater control. The architectural re-design includes a mix of brick with new, large glass windows. The addition of a parking structure will bring the site into conformance with parking requirements, providing more than required under zoning. With the changes in how office space is developed, there can be more demand for parking than required under current zoning because the amount of office space per employee has been decreasing. This project will provide parking in combination with transportation demand management to ensure the parking demand is met on-site.The request for more parking than required is supported by the suggested employee per square foot proposed. One suggestion is to defer developing the southern surface parking areas, and reserve them as shadow parking and determine if tenants will require the additional parking. 2. The use as developed will not adversely affect the neighborhood. Conditionally Met: Historically, the site was industrial in nature and used the neighborhood for access to the site. Vehicles and truck deliveries accessed the site from Crawford Street and Grove Street the same as the proposed. That historic use was a 24 hour per day, seven day per week operation in three shifts. The previous use of the site produced substantial vehicle traffic and parking often spilling into the neighborhood. The use also was industrial in nature with associated noise. Page 6 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report The current proposal is an office use which is a more neutral and less impactful use for the surrounding neighborhood. Parking has been an issue on the site so the Petitioner has proposed a garage to ensure that parking can be accommodated onsite,which will minimize overflow parking into the neighborhood. The garage structure is the primary component of the project that changes the existing condition. From an impact perspective, the Petitioner submitted shadow studies as part of supplemental information which indicates the project, including the new parking structure,will not cast shadows on the abutting residences to the south. The garage also removes a substantial amount of surface parking which was directly adjacent to the direct abutters to the south and incorporates plantings to screen the structure from the neighbors. The increased landscaped areas will contribute to improved neighborhood perception, as the current parking area is dilapidated and not screened with landscaping. The surface parking to remain, if eventually constructed, will have an eight foot wide landscaped buffer adjacent to the residential property. The existing industrial and office use could continue as is, but the petitioner has requested to bring the parking into compliance, which requires the construction of a parking structure. As part of that sit e improvement,the petitioner has agreed to minimize many of the existing site impacts with several on and offsite improvements. Initially,the preferred options for site access was proposed to recreate a two-way access point on Crawford Street. A peer review of that option indicated that this would significantly degrade the intersection at the Arlington/Nichols so the plan was revised to keep the existing access points. Staff continues to work with the petitioner to look at any option that might reduce the traffic impacts on neighborhood street. The petitioner has agreed to provide mitigation of$250,000 for off-site traffic/ROW improvements within the neighborhood. These funds will be used to make the pedestrian and vehicular access in the surrounding area safer. The proposal also minimizes the impacts to the neighborhood from noise sources and exterior lighting with full cut-off lights and screening of all HVAC. These items are discussed in more detail in criterion §9.03 (c)(10), below. During construction, the Petitioner proposed a primary construction entrance on Grove Street. Staff recommends that the use of neighborhood streets for construction purposes be minimized as much as possible.A construction management plan and an erosion/sediment control plan will be required as part of the Building Permit. 3. There will be no nuisance or serious hazard to vehicles and pedestrians. Conditionally Met: The site has a main entrance on Grove Street with a sidewalk that connects to Coolidge Square and toward the Arsenal Corridor. No changes are proposed and this area meets all pedestrian access needs along the frontage. The proposal also includes a pedestrian connection to the adjacent Watertown-Cambridge Greenway that runs along the property to the Northeast. Initially, Staff was concerned that the connection from the site to the path goes through the loading Page 7 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report zone but the petitioner has now provided clear striping for multimodal access through this area. Staff suggests that any connection to the Greenway have final design review and acceptance by DCDP and DCR. The parking garage is designed to allow access to the building at the ground level. The main parking area provides direct access to the rear 'main' entrance to the building in a safe manner. Pedestrian safety is adequate in this area. The rear parking area to the south does not provide pedestrian sidewalks but the traffic through this area is not substantial and there appears to be safe options for walking within the drive aisles. The project is required to provide granite curbing and a sidewalk along the project frontage on Crawford Street. The petitioner has also agreed to provide $250,000 in funds for offsite pedestrian and vehicular improvements. 4. Adequate and appropriate facilities will be provided for the proper operation of the proposed use. Conditionaliv Met: The proposal will be required to meet all building, health, and safety requirements. The Petitioner states the development and renovation will be designed in accordance with the Massachusetts State Building Code. The Petitioner's Stormwater Drainage Calculations and Stormwater Management Plan (Plan), describes the existing condition and proposed new stormwater management infrastructure to be installed. The Plan notes that the majority of stormwater currently drains towards the center of the site,which is below grade. The Plan states that after redevelopment,the peak runoff rates will decrease substantially. Proposed new stormwater infrastructure will include deep sump and hooded catch basins, bio-retention areas, and "proprietary treatment units" as pre-treatment. These systems will be augmented by a sub-surface infiltration chamber to achieve the required removal of 80%of the total suspended solids. The Petitioner also has a Stormwater Operations and Maintenance Plan (SOMP). DPW Staff notes that review and final approval of all roof connections and the operation of the stormwater system will be required. Staff also recommends considering options for increasing the capacity of the infiltration system and providing smaller systems to infiltrate runoff from the rear parking area. Infiltration in addition to reducing stormwater flows is a priority for Watertown because it provides the highest treatment level for phosphorous. Staff notes that the Department of Public Works shall have final review and approval of the stormwater management system design. In regards snow removal,the Petitioner has committed to a snow management and removal plan to be included in the SOMP. Based on DPW Staff comments,the SOMP was amended to not allow deposit of snow in the bio-swales. The SOMP documents will be made available to the Town DPW, upon request. The enforcement mechanism for the SOMP shall be reviewed and approved by DPW. Sheets C-1,Site Layout Plan show the location of the existing transformer and electrical connection box in the northwest corner of the landscaped area along Grove Street, behind a concrete wall. Landscape screening should be provided to shield this equipment from public views. Sheets L-2 and L-3, Planting Plan/Details, indicate that trees are to be planted in this area. The width of this area may be too narrow to accommodate both the electrical equipment and the proposed trees, therefore,the screening will be subject to DCDP staff review and approval. Page 8 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report The existing underground water main,fire protection service and municipal sanitary sewer line will be used. The Petitioner also states a hydrant will be relocated and the sewer service connection will be inspected and repaired as needed with DPW oversight. Sheets C-1,Site Layout Plan show the location of two trash containers to the Northwest side of the new parking garage. The Petitioner states, "The dumpsters will be...screened by planting and fences from the residential neighbors to the south. This location is about 40 feet farther from the neighbors than the existing condition." The Petitioner should ensure that there is adequate storage capacity inside and exterior to the building to provide enough storage for trash and recyclables between pickups. As noted above,the Petitioner has provided a proposed Planting Plan/Details, showing various tree, shrub, and plant species. The final landscaping proposal should have a final review by DCDP to ensure species appropriateness, mix, size, quantity and spacing prior to construction. The Petitioner has provided exterior lighting information, including fixture cuts and a lighting plan, and exterior lighting is also addressed in detail in the Site Plan Review Criteria under the Design criterion. Site Plan Review Criteria§9.03(c) Prior to the official filing of the Application, a meeting of the Site Plan Review Committee was held on August 26, 2014. Present at the meeting were members of the Site Plan Review Committee (consisting of Town Staff and committees) and the Petitioner,who presented the proposal, after which members of the Committee were invited to respond with questions, comments, and suggestions. Planning Staff has reviewed the ten criteria for Site Plan Review provided in §9.03(c) of the WZO and incorporated Committee comments where appropriate. The following are the findings as identified through analysis of the updated project and the Committee's review: 1. Preservation of Landscape: "The landscape shall be preserved in its natural state, insofar as practicable, by minimizing tree and soil removal, and any grade changes shall be in keeping with the general appearance of neighboring developed areas.Adequate landscaping shall also be provided, including screening of adjacent residential uses, provision of street trees, landscape islands in the parking lot and a landscape buffer along the street frontage." Conditionally Met: The previous use of the subject property included a substantial amount of asphalt pavement. According to a table on Sheet C-1/C-1(A),the site currently has 6.9%as open space/green space/landscaped area. The Petitioner proposes to increase this percentage to just under 27%. Sheets L-2 and L-3, Planting Plan/Details, as well as the Petitioner's supplemental information (11x17-inch colored, spiral bound documents) provide details on the proposed new landscaped areas, including proposed plant species, sizes and quantities. The Petitioner also proposes screening at the South face of the new parking structure, created by using two types of bamboo in combination with other plantings. Page 9 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report 2. Relation of Buildings to Environment: "Proposed development shall be integrated into the terrain and the use, scale and architecture of existing buildings in the vicinity and shall be in accordance with the Comprehensive Plan or other plans adopted by the Town guiding future development. The Planning Board may require a modification in massing so as to reduce the effect of shadows on abutting property in all districts or on public open space." Conditionally Met: The existing building will have updated fagade treatments but will not be altered substantially on the exterior. It appears that all of the proposed work for the building would be allowed through the Building Permit process.The parking structure is proposed to be to the rear of the building and be screened by the structure from Grove Street. The Petitioner states this criterion is met, because the proposed new garage "is set down within the existing bowl...placed over 35 feet from the residential property line." The height of the garage, due to the grade change, and partially putting one level underground, results in a height of 35 feet above average existing grade. The garage is integrated into the site and allows more landscaping and planting between it and the neighborhood than the existing conditions. The Petitioner also submitted shadow studies as part of supplemental information, which indicate the project, including the new parking structure will not cast shadows on the abutting residences. 3. Open Space: "All open space required by this Zoning Ordinance shall be so designed as to maximize its visibility for persons passing the site, encourage social interaction, maximize its utility, and facilitate its maintenance." Conditionally Met: The proposed redevelopment will increase the amount of open space on the site through creation of new landscaped areas. The site also has limitations due to the layout of the existing building. Because of this,the open space is being retained along the front of the site and will be updated. The interior parking area is being completely reconfigured and open space will provide stormwater functions as well. The open space will provide a visual presence at a main entrance to the building from the parking lot. This area was initially proposed to have several drive aisles and smaller landscape beds and was updated to provide a single drive and a consolidated landscaped area within a central landscape. Other open space will be adjacent to the residential neighborhood and will serve as a buffer to the drive aisle and parking to the rear/south of the garage. An area between the building and the former rail corridor will also be restored to open space which will add to the buffer of the use and the proposed Greenway. 4. Circulation: "Special attention shall be given to traffic circulation, parking areas and access points to public streets and community facilities in order to maximize convenience and safety of vehicular, bicycle and pedestrian movement within the site and in relation to adjacent streets." Conditionally Met: In terms of pedestrian circulation,the renovation will create three building entrances. The existing entrance on Grove Street will be maintained, allowing access to the second floor. A new main entry will be created facing the U-shaped area created by the existing building and new parking garage. People entering the building that way will gain access to the first floor. A third entrance will be created, accessible from the at-grade level of the parking garage, and will be accessible to pedestrian and bicycle traffic from the future Watertown Cambridge Greenway to the West. Page 10 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report Sheets C-1,Site Layout Plan, now proposes to keep the vehicular site circulation similar to what is existing. Original concepts retain the one-way in access only from Grove Street but proposed reestablishment of two-way access from the Southwest on Crawford Street. A Town initiated peer review indicated that the proposed two-way, or another option of a reversed one-way would not be acceptable for the operation of the signal at the Arlington Street intersection. The preferred option would be to have a driveway with in and out on Grove Street. Without the cooperation of the adjoining property this alternative is not feasible. Therefore,the only remaining options (as indicated in the Peer Review) was to maintain the existing road network configuration with left turns on to Crawford from the site and in only on to Crawford from the Arlington streetlights. The total amount of parking proposed on the site is 349,with 290 in the garage and 59 surface spaces, which is 38 more spaces than stipulated by zoning. As previously identified, redeveloped office space often proposes less area per employee, which can increase demand for parking overall, even with employee incentives and transportation demand management. As discussed,the Petitioner should consider shadow parking of the 18 proposed parking spaces closest to Crawford Street since they are the farthest from the building, lack good pedestrian connections to the rest of the site, and will not be lit. If a tenant requires more parking,the shadow parking could be easily converted to active parking spaces. §6.07(a)(1) requires a Petitioner to provide "one bicycle parking space for every 15 automobile spaces, with a minimum of 4 and a maximum of 50..." According to the Petitioner, 24 bike parking spaces will be provided,which is the required number(349 vehicle spaces/ 15 = 23.6).The Site Layout Plans [Sheet C- 1/C-1(A)] show a location on the Northeast corner of the new parking garage for bike racks with a 20- bike capacity. Also,the Petitioner clarified that inverted "U" bike racks will be provided per§6.07. Staff also strongly recommends the Petitioner provide secure bicycle storage on the site for employees. 5. Surface Water Drainage: "Special attention shall be given to proper site surface drainage so that removal of surface waters will not adversely affect neighboring properties or the public storm drainage system. Proposed developments shall seek to retain storm water runoff on site to the maximum extent possible, incorporating best practices in storm water management and Low Impact Design techniques. In cases where storm water cannot be retained on site, storm water shall be removed from all roofs, canopies and paved areas and carried away in an underground drainage system." Conditionally Met: The proposed redevelopment will improve the existing conditions for surface water retention, as the site is almost entirely paved;there currently is minimal stormwater management at the site. According to the Petitioner,the proposed project "will reduce its impact on the municipal drainage system, and the Charles River through rain gardens/bio-retention areas, proprietary treatment units, permeable pavers, subsurface infiltration systems..."and an overall reduction in rates of runoff post redevelopment. Staff notes that the stormwater management design will require a final review and approval of the proposed system by DPW. Page 11 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report 6. Utility Service: "Electric, telephone, cable TV and other such lines and equipment shall be underground. The proposed method of sanitary sewage disposal and solid waste disposal from all buildings shall be indicated." Conditionaliv Met: The Petitioner has stated in the application "the existing utility services will be utilized for the redevelopment." This includes the in-place, underground water main,fire protection service and municipal sanitary sewer line. The Petitioner also states a hydrant will be relocated and the sewer service connection will be inspected and repaired as needed. The Petitioner's narrative does not address solid waste or recyclables management, although Sheet C-1 shows the location of two trash dumpsters. Sheet C-1 also show the location of the existing electrical/transformer pad, in the Northwest corner of the site, close to Grove Street,within a concrete enclosure and in a landscaped area. The project should be conditioned to ensure that the transformer pad is adequately screened. 7. Environmental Sustainabilitii: "Proposed developments shall seek to diminish the heat island effect,employ energy conscious design with regard to orientation, building materials and shading, utilize energy-efficient technology and renewable energy resources;and minimize water use." Conditionaliv Met: The Petitioner's application states the proposed redevelopment will "significantly reduce the heat island effect by..."a new white/reflective roof, replacing some surface parking with a parking garage, adding landscaped areas, and shade trees. The Petitioner's application states "the proposed renovation will utilize energy-efficient systems wherever possible...including energy recovery roof top HVAC units, energy-efficient lighting, and automatic lighting controls." Other proposed energy efficiency features will include new window and curtain wall systems, shading devices on South face to reduce the HVAC load, low VOC paints, and low flow plumbing fixtures. The Petitioner also states that "roof gardens and photovoltaic arrays are also being considered on portions of the existing building roof, depending on the tenants expected to occupy the building." The green roof elements and roof terrace gardens proposed in the Petitioner's August 2014 submittal have been removed from the October 14, 2014 Control Plans and only roof-top solar is part of the submittal (plans are to use the entire rood for solar). A green roof still might be an option dependent on tenancy. 8. Screening: "Screening, such as screen plantings, shall be provided for exposed storage areas, exposed machinery installations, service areas, truck loading areas, utility buildings and structures, and similar accessory areas and structures in order to prevent their being incongruous with the existing or contemplated environment and the surrounding properties." Conditionaliv Met: The existing transformer is shown to be within a landscaped area. The renovated building also have several rooftop HVAC units,which should be screened, or placed behind or below the roof cornice so that they are not visible from public views. Page 12 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report Conditional approval should be based on the Petitioner providing the location of mechanical and HVAC systems with appropriate screening as part of the building permit approval. 9. Safety: "With respect to personal safety, all open and enclosed spaces shall be designed to facilitate building evacuation and maximize accessibility by fire, police, and other emergency personnel and equipment." Conditionally Met: The Petitioner states that the proposed structures will be built in accordance with all applicable Federal, State, and Local laws, and with a new fire suppression system, new fire alarm system emergency lighting, and an elevator with a stretcher entrance. The two access points from Crawford Street are wide enough to accommodate emergency vehicles. 10. Design: "Proposed developments shall seek to protect abutting properties from detrimental site characteristics resulting from the proposed use, including but not limited to air and water pollution, noise, odor, heat,flood, dust vibration, lights or visually offensive structures or site features." Conditionally Met: The Petitioner states that the proposed project "is designed to improve views from and detrimental impact on abutting properties"and will accomplish this by the revised stormwater management systems, increased landscaping, exterior fagade renovations, and moving the trash dumpsters farther away from the abutting residences. There was environmental contamination at the site, dating from urban fill used to develop the site in 1945. Since that time,the site "closed out" in accordance with Massachusetts Department of Environmental Protection (MA DEP) regulations, with an Activity Use Limitation (AUL) in place that restricts the site to non-residential use. The Petitioner also states that "since taking ownership of the property, Cressett Group has initiated additional remedial measures in order to clean up the site beyond what is required by MA DEP regulations." At the Community Meeting on September 29, 2014, several persons in attendance expressed concern for noise levels at the site, post-construction, particularly with respect to HVAC equipment,fans to ventilate the garage, and any onsite emergency generator. Staff notes that the MA DEP administers the Air Quality regulations, and that "noise" is defined in these regulations as "a sound of sufficient intensity and/or duration as to cause a condition of air pollution." This is typically accomplished by administrative controls (limits on when construction can occur during the day and week) and physical controls(mufflers on equipment, and sound attenuation enclosures for HVAC and ventilation equipment, and around any onsite emergency generator). The proposed project includes parking lot pole mounted and on-building mounted lights. Sheet L-4, Exterior Lighting Calculations, details the parking lot pole and on-building lighting. Those closest to the Atrium School will be on a 14-foot pole, equipped with a shield, to reduce the amount of light thrown towards that property line.The on-building mounted light is a rounded trapezoidal LED wall-pack that is full cutoff. . The proposed mount height on the building is 14 feet above grade and on the new garage is 10 feet above grade, except for those at the vehicle entrances. The only lights of concern for potential abutter impacts are those on the south side of the proposed new garage but the distribution pattern will reduce the amount of light thrown towards the property line. Moreover, Sheet L-4 estimates a reading Page 13 of 18 65 Grove Street February 6, 2015 ZBA-2014-27 SP/SR Staff Report of under one foot-candle well inside the property line. Finally, the Petitioner has proposed a landscaped buffer and a planting bed of bamboo directly abutting the South face of the garage. Taken together these factors should reduce the impact of the on-garage mounted wall-packs to abutting residential properties. The garage includes several types of lighting including a wall fixture,two types of ceiling lights, a step light, and a pole mounted light, all of which use LEDs. The step light is of little concern to staff, because it is mounted in the sidewall of the stairwell, and is aimed in such a way as to illuminate the stairs. Of these lights, only those along the parking garage's south face are a concern for lighting impacts to abutting properties. However, it appears the ceiling fixtures will be mounted in such a manner so the light will be directed inwards,towards the floor of each parking deck. This and the proposed landscaping should reduce any off-site impacts. The last garage light style is a pole-mounted fixture used on the uppermost deck. The Petitioner indicates there will be three (3) double-headed versions of this light, with the luminaire side arm mounted, 10 to 12 feet from the finished surface located near the centerline of the parking deck. Whether or not these lights pose an impact to the abutting properties depends on the viewing angles into the site, and the proposed height of the vegetated screen. The Petitioner's renderings show the bamboo reaching heights tall enough to screen these lights. V. STAFF RECOMMENDATION: The proposed project meets the criteria set forth under§9.03(c), §9.05 (b), and is consistent with the general purpose of the Ordinance outlined in §1.00 of the WZO.
