3 French-American School of New York White Plains Campus Construction Management Plan The goal of this Construction Management Plan (CMP) is to identify the strict controls on all aspects of the construction that would be implemented by FASNY s construction manager. This CMP also identifies the specific communication protocol that would be in place to facilitate information flow between FASNY, its construction manager, the City of White Plains, and residents of the surrounding neighborhoods. FASNY intends to provide information on a regular basis during the construction period on the nature and intensity and schedule of construction activities occurring on the Project Site. The Construction Management Plan is subject to the approval of the Commissioners of Building, Public Safety, Public Works, Traffic, and Planning and the Environmental Officer. Prior to the issuance of any building or excavation permits, FASNY and its construction management team, including principal contractors, would be required to meet with representatives of the City Departments of Building, Public Works, Public Safety, and Planning and the Environmental Officer, to review the project s Construction Management Plan and to ensure that all responsible parties understand their responsibilities under that Plan. In addition, this Plan addresses the maintenance of the respective properties during the construction phase. Prior to the commencement of construction, FASNY would be required to maintain its property, and ensure that it is clean and free from hazardous conditions. The City of White Plains Standard Construction Details and Specifications would supersede anything by FASNY which is inconsistent with those standards. A note to this effect is included on the Site Plans for the Project. CAMPUS CONSTRUCTION SCHEDULE, TIMELINE, AND PHASING Construction of the Campus and related improvements is expected to occur in two primary phases. Each of the primary phases would have separate sub-phases to comply with the NYSDEC General Permit for Construction Activities (GP ) limitation on a maximum of five (5) acres of disturbance. On the campus portion of the Site, Phase I encompasses all the improvements proposed on Parcel A and Parcel B, including the High School, Middle School, Gymnasium and Performing Arts buildings, a running track, tennis courts, soccer and baseball fields and an outdoor basketball court, as well as improvements to Ridgeway and Hathaway Lane. Phase II of the campus construction encompasses all the improvements proposed on Parcel D, including the Lower School, a soccer field and outdoor play areas. Construction of Phase I is anticipated to begin in the spring of 2013 and be completed by summer of Construction of Phase II is anticipated to begin in the spring of 2018 and be completed by the summer of Figures 15-1 through 15-4 depict the phasing plans and areas for construction worker parking and staging of construction equipment and materials. The construction phasing plans and Construction Management Plan have been developed to ensure that Phase II can be completed without any reliance on Phase I. That is, no construction parking or equipment and material staging required for Phase II would occur on Parcel A. FASNY intends to occupy the High School and Middle School immediately upon completion. The Phase II phasing plan accommodates for the need to separate regular FASNY traffic (students, buses) on Parcel A from construction traffic and construction activities on Parcel D. PHASE I Phase I would be broken into sub-phases to limit as much as possible the area of the Project Site disturbed at any one time. Table M-1 lists the sub-phases and activity to occur in each sub-phase of Phase I. The sequence of construction would begin with renovations to the interior of the existing Clubhouse and Annex structures to become the High School. An inspection of the interior of the Clubhouse and Annex would be performed to identify any suspect asbestos containing materials and lead-based paint. Due to the Page 1 of 11

4 age of these structures, it is anticipated that some suspect asbestos containing materials and lead-based paint might be encountered. All regulated materials would be removed from the buildings, contained, and transported off-site for appropriate disposal following all applicable rules and regulations. Interior construction within the Clubhouse and Annex would likely continue while exterior grading and construction activities occur. After required soil erosion and sediment controls are in place, site work would begin with the construction of stormwater management basins (SMB-1A) near the existing tennis courts. A portion of these basins would serve as a temporary sediment basin during construction. This would result in the westernmost existing curb cut on Ridgeway being removed. Once these improvements are constructed, vegetation removal and mass grading of the proposed driveway, parking areas, and building pads for the Middle School, gymnasium, and performing arts buildings would begin. This area totals approximately 9.5 acres, so grading would be done in two stages utilizing material from areas of cut to the east in areas requiring fill to the west. FASNY may request a waiver through the City s Department of Public Works of the NYSDEC General Permit (GP ) limitation on five (5) acres of disturbance to allow for the mass grading in Phase I-D to occur at one time. FASNY believes that use of appropriate erosion and sediment control measures can effectively protect against any soil erosion during grading of the larger area. If this request for a waiver is not granted, Phase I-D would occur in two separate phases each of less than five (5) acres in size. After grading, these areas would be stabilized as required and construction of the main site access driveway would begin with the new curb cut on Ridgeway. This would serve as the stabilized construction entrance for the remainder of construction of Phase I.

Once constructed, this curb cut would be controlled with a gate to minimize construction traffic on Hathaway Lane. The proposed parking area to the north of the school buildings would be constructed to the point where it would serve as a temporary staging area and parking for construction workers. Page 2 of 11

5 Phase I building construction begins with the expansion area connecting the existing Clubhouse and Annex structures, followed by the gymnasium and Middle School. Construction of these buildings would include the subsurface stormwater management facility in the academic quadrangle, as well as sidewalks and other related improvements connected with these structures. Concurrently, roadway improvements within Ridgeway and Hathaway Lane would be constructed along with improvements to the driveway in front of the High School along Ridgeway. Once the areas surrounding the High School expansion, gymnasium and Middle School have been stabilized, construction of the athletic fields would begin on the western portion of Parcel A. Construction would progress from south to north, starting with the tennis courts, then the running track and turf soccer field, then the combination softball / turf soccer field, then the natural grass soccer field. Construction of the baseball field on the southern portion of Parcel B would follow, and lastly the outdoor basketball court near the Middle School would be constructed. The last buildings to be constructed in Phase I would be the performing arts building with its window wall connection to the gymnasium and the greenhouse at the eastern edge of the academic quadrangle. Finally, the main parking area on Parcel A would be completed (this area would be used as a temporary staging area during earlier phases of construction). PHASE II Phase II would also be broken into sub-phases to limit disturbance areas within Parcel D. Table M-2 lists the sub-phases and activity to occur in each sub-phase of Phase II. Table M-2 Phase II Construction: Sub-Phases Sub-Phase Activity II-A Site-wide (Parcel D) Soil Erosion & Sediment Controls II-B Construct stormwater management basins II-C Mass grading of driveway, parking, and drop-off area II-D Construct new curb cut on Hathaway Lane and site access driveway II-E Construct temporary parking/staging area II-F Mass grading of Lower School building pad II-G Construct Lower School building II-H Mass grading of parking area II-I Construct new curb cut on Hathaway Lane and parking II-J Construct soccer field Notes: See Figures 15-3 and After required soil erosion and sediment controls are in place, site work would begin with the construction of the stormwater management basin (SMB-2A) north of the proposed Lower School building. A portion of this basin would serve as a temporary sediment basin during construction. Once these improvements are constructed, mass grading of the bus loop and drop-off traffic loop and short-term parking area would begin. After grading, this area would be stabilized as required and construction of the main site access driveway would begin with the new curb cut on Hathaway Lane. This would serve as the stabilized construction entrance for the remainder of construction of Phase II. The proposed bus loop and short-term parking area would be constructed to the point where it would serve as a temporary staging area and parking for construction workers. Mass grading of the Lower School building pad would be the next item in the construction sequence, followed by the construction of the Lower School building. Site work would continue with the grading and construction of the staff, teacher, and visitor parking lot to the south of the Lower School building. This includes a second new curb cut on the east side of Hathaway Lane. Page 3 of 11

6 Once this area is stabilized, the artificial turf youth soccer field and play areas would be constructed. Finally, the temporary staging area would be completed as the bus / drop-off traffic loop and short-term parking area. CONSTRUCTION STAGING Staging areas for construction equipment and materials have been identified in different areas of the Site during various phases of construction. Initially, when Phase I construction begins with renovations of the interior of the existing Clubhouse and Annex structures, the area currently serving as the loading space for the existing kitchen in the clubhouse would serve as a staging area, along with the area to the west of the Annex structure and the existing paved parking area north of both existing structures. The proposed parking area to the north of the school buildings would serve as a staging area for the remainder of Phase I, once this area has been graded and partially constructed. In addition, three areas have been identified on the project Site Sediment & Erosion Control Plans for the stockpiling of soil. These areas would be surrounded by a double-row of silt fence and stabilized as required during construction. The existing paved parking area on Parcel D, at the northeast corner of Ridgeway and Hathaway Lane, would serve as a staging area at the beginning of Phase II construction activity. Once the proposed bus loop and drop-off traffic loop and short-term parking area has been graded and partially constructed, it would serve as a staging area for the remainder of Phase II. In addition, the area for the proposed youth soccer field has been identified on the project Site Sediment & Erosion Control Plans for the stockpiling of soil. This area would be surrounded by a double-row of silt fence and stabilized as required during construction. CONSTRUCTION PARKING AND SITE ACCESS The Construction Management Plan for the Project requires that FASNY ensure through appropriate measures, to be agreed upon between the City and FASNY, that the parking location requirements for construction workers would be strictly enforced. As part of the Construction Management Plan, FASNY has submitted a parking plan for construction workers that designates the construction manager as the responsible party to ensure that the proposed parking plan is enforced. Once a parking plan is approved by the City for construction workers, FASNY shall be required to provide all construction contractors with information on where their workers and the subcontractors are permitted to park and provide clear consequences for the failure to follow these regulations. Several areas have been identified for construction worker and construction equipment parking during various phases of construction. During Phase I, the existing paved parking area on Parcel D, east of Hathaway Lane, would be utilized for construction worker parking. Access to this area would be via the existing curb cut on Hathaway Lane. The existing paved parking areas adjacent to the existing Clubhouse and Annex structures on Parcel A would initially serve as additional construction worker parking and construction equipment parking. Access to these areas would be via existing curb cuts on Ridgeway and Hathaway Lane, including at least one stabilized construction entrance for construction equipment. Once the proposed main parking area on Parcel A, to the north of the school buildings, has been graded and partially constructed, it would serve as a parking area for construction workers and equipment for the remainder of Phase I. Access to this area would be via a new curb cut on Ridgeway, which would serve as a stabilized construction entrance to the site. Limited access for construction equipment would also be provided via a new curb cut on Hathaway Lane. Construction workers would continue to utilize the existing paved parking area at the south end of Parcel D at the beginning of Phase II. Once the proposed short-term parking area has been graded and partially constructed, it would serve as an additional parking area for construction workers and for construction Page 4 of 11

7 equipment for the remainder of Phase II. Access to this area would be via a new curb cut on Hathaway Lane, which would serve as a stabilized construction entrance to the site. These areas would operate during the hours of construction permitted by the City of White Plains Municipal Code, Chapter 3-4, Noise Pollution. Overnight parking of construction vehicles and/or equipment would be on-site and generally within the areas designated above. Construction worker trips and construction equipment accessing the Site can potentially impact the City s street system. The impacts related to heavy equipment damaging roadways would be mitigated by the fact that the majority of such equipment would remain on-site for the duration of each Phase of construction, thereby minimizing trips on the City s streets. Requirements for maintaining surrounding streets clean of dirt and debris are included in the project s Site Sediment & Erosion Control Plans. These requirements would be reiterated as the responsibility of FASNY s contractor in the Construction Management Plan prepared for the Project. FASNY would be responsible to ensure that all street and/or roadway infrastructure which may be damaged as a result of construction activities would be repaired to City standards. Financial mechanisms to ensure stabilization of the Site and any other improvements would be implemented in conjunction with the City of White Plains. FASNY would be responsible for the repair and replacement of any areas of roadway or right-of-way damaged as a result of the construction process. This would be clearly stated in the Project s construction documents and specifications as the responsibility of FASNY s contractor(s). TRANSPORTATION Construction of the Proposed Project would create daily construction-related traffic to and from the Project Site, including construction workers and the delivery of materials and equipment, all of which would be regulated by the City s Construction Management Protocol. The numbers and types of vehicles would vary depending on the phase of construction. The Proposed Project is anticipated to generate construction traffic during the morning and afternoon. Approximately 75 auto and 25 truck trips would arrive at the Site in the morning and depart from the Site in the afternoon. The typical construction arrival/departure times occur before the standard commuter peak hour. However, to be conservative, it was assumed that these 100 vehicles arrive during the standard commuter peak hour. A capacity analysis conducted at the intersections of Ridgeway and Mamaroneck Avenue and Ridgeway and North Street show that level of service would not change from No Build Conditions during each phase of construction. Truck traffic would primarily travel on I-287 and utilize both Mamaroneck Avenue and North Street to Ridgeway to access the Project Site. It is the Applicant s belief that this level of construction activity would not significantly impact traffic operating conditions in the Study Area. During the mass grading phase of construction, it is estimated that approximately 20,000 cubic yards of fill would need to be imported to the Project Site. Pursuant to City of White Plains regulations, only documented clean fill would be accepted on the Project Site. Most of this fill would be required to achieve a level grade on Parcel D during Phase II; but some amount of fill would be required for grading of Parcel A during Phase I. FASNY anticipates that fill would be transported to the Project Site using a standard 25 cubic yard truck. FASNY estimates that a maximum of 20 to 25 such trucks would be required per day (roughly three (3) trucks per hour) during the six (6) to eight (8) weeks required to complete the grading phases. These trucks would be in addition to the approximately 25 truck trips described above and would be directed to arrive at the Site outside of either the morning or afternoon/evening peak hours. It is the Applicant s belief that these additional trucks would not cause any decrease in levels of service at intersections of Ridgeway and Mamaroneck Avenue and Ridgeway and North Street.

8 Construction on-site would occur primarily between normal business hours on weekdays. Delivery times would be carefully coordinated to minimize the impact on rush hour traffic, pedestrians, and residents. A construction schedule would be coordinated with City agencies, as required by the City s Construction Management Protocol. Truck movements would typically be spread throughout the day on weekdays. Wherever possible, the scheduling of deliveries and other construction activities would take place during off-peak travel hours. Upon completion of the High School and Middle School (Phase I), FASNY intends to occupy the buildings and use them for school use. When Phase II commences, the Construction Management Plan prepared for the Project would ensure that all FASNY school traffic on Parcel A is separated from Phase II construction activity and traffic on Parcel D. This separation would ensure the safety of FASNY students and staff during the period when Phase II construction overlaps with occupancy of the High School and Middle School. These traffic and transportation conditions would be temporary and not result in significant adverse impacts on traffic and transportation conditions. AIR QUALITY The principal air quality impact associated with construction activities is the possible generation of fugitive dust, which can vary widely in terms of volume and size of particulate matter generated. Fugitive dust is associated with earth moving, such as site grading, filling, and excavation for foundations. A large proportion of the fugitive dust generated by construction activities would be of relatively large particle size, and would be expected to settle to the ground within a short distance. To minimize these problems, erosion and dust control procedures, which would be regulated by the City s Construction Management Protocol, would be followed during construction and would include: Minimizing the area of disturbed soil by careful planning of grading operations so that only the areas needed for any particular construction activity are disturbed; Minimizing the time span that soil is exposed; Spraying water on dusty surfaces; Utilizing ultra-low sulfur diesel equipment; and Using drainage diversion methods (silt fences) to minimize soil erosion during site grading. Mobile source emissions may result from the operation of construction equipment, trucks delivering materials and removing debris at the Project Site. Localized increases in mobile source emissions would be minimized by using ultra-low sulfur diesel fuel for all on-site construction equipment. Delivery trucks and/or other construction equipment engines would not be permitted to remain idling during unloading or other inactive times. It is the Applicant s belief that no significant impacts on the local community from fugitive dust or emissions are expected to occur as a result of the Proposed Project. NOISE Construction of the Proposed Project would generate noise and vibration from construction equipment, construction vehicles, and delivery vehicles traveling to and from the Project Site. Noise levels caused by construction activities would vary widely, depending on the phase of construction demolition, excavations, foundation, construction of the structures, etc. and the specific task being undertaken. All construction activities would be conducted in full compliance with existing regulations (Chapter 3-4, Noise Pollution ), including local day and hour construction limitations, and would adhere to the City s Construction Management Protocol. Page 6 of 11

9 Local, state, and federal requirements mandate that certain classifications of construction equipment and motor vehicles be used to minimize adverse impacts. Thus, construction equipment would meet specific noise emission standards. Usually, noise levels associated with construction and equipment are identified for a reference distance of 50 feet, as shown in Table M-3. Notes: Sources: 2 3 Table M-3 Typical Noise Emission Levels For Construction Equipment Equipment Item Noise Level at 50 Feet (dba) Air Compressor 81 Asphalt Spreader (paver) 89 Asphalt Truck 88 Backhoe 85 Bulldozer 87 Compactor 80 Concrete Plant 83 (1) Concrete Spreader 89 Concrete Mixer 85 Concrete Vibrator 76 Crane (derrick) 76 Delivery Truck 88 Diamond Saw 90 (2) Dredge 88 Dump Truck 88 Front End Loader 84 Gas-driven Vibro-compactor 76 Hoist 76 Jack Hammer (Paving Breaker) 88 Line Drill 98 Motor Crane 93 Pile Driver/Extractor 101 Pump 76 Roller 80 Shovel 82 Truck 88 Vibratory Pile Driver/Extractor 89 (3) 1 Wood, E.W., and A.R. Thompson, Sound Level Survey, Concrete Batch Plant; Limerick Generating Station, Bolt Beranek and Newman Inc., Report 2825, Cambridge, MA, May New York State Department of Environmental Conservation, Construction Noise Survey, Report No. NC-P2, Albany, NY, April F.B.

Swanson, Regulation of Construction Activity Noise, Bolt Beranek and Newman, Inc., Report 2887, for the Environmental Protection Agency, Washington, D.C., November 1974, except for notated items. Significant noise levels typically occur nearest the construction activities, and may reach as high as 90 A- weighted decibels (dba) under worst-case conditions. The level of noise impacts at local receptors would depend on the noise characteristics of the equipment, the activities involved, the hours of operation, and the location of sensitive noise receptors. Noise levels would decrease with distance from the construction site. Increased noise levels due to construction activity can be expected to be most significant during the early construction phases such as clearing and excavation, which would be relatively short in duration (approximately one month) and intermittent based on the equipment in use and the work being done. While the exact sequence and duration of construction activity would vary slightly, it is known that certain equipment including excavators, bulldozers, backhoes, graders, and dump trucks would be required. Construction operations, for some limited time periods, would result in increased noise levels that may be intrusive and annoying and may significantly increase ambient noise levels. Construction activities would Page 7 of 11

10 comply with the hour limitations in Section 3-4 of the Zoning Ordinance, Noise Pollution, to minimize noise intrusion from construction activities during weekends and nights when most families are at home. As specified in the Construction Management Plan, all construction equipment would be the latest model equipment with state-of-the-art sound attenuation practices. Because of the limited duration, it is the Applicant s belief that these impacts would not constitute significant adverse noise impacts. BLASTING PROTOCOL The Construction Management Plan complies with the City of White Plains blasting protocol (Section of the Municipal Code, Rock Excavations ). All other applicable requirements relating to rock removal would be followed. No rock was encountered in development areas during preliminary geotechnical investigation and no blasting is anticipated. CONSERVANCY CONSTRUCTION Implementation of the Conservancy Master Plan would be coordinated with the Campus construction and would be subject to all conditions of approval of the overall Special Permit for the Property and available future financial resources. Implementation of the Conservancy would not require extensive disturbance. Any equipment used to restore the Conservancy property would be similar to maintenance equipment currently used to maintain the golf course and Property; but may also include use of small-scale construction equipment such as a tractor or back-hoe as well as hand-held equipment such as a chain saw, drill seeder, mulching mower, or post-hole borer. Master plan implementation would rely heavily on modifying land management practices rather than traditional construction activity. This being the case, FASNY intends to initiate changes to current maintenance activities that would begin immediately. FASNY has already ceased applying pesticides, fungicides, herbicides, and insecticides to the Property. FASNY intends to target removal of invasive and undesirable plant species, as well as introduce native vegetation types appropriate for the Property and the defined habitat types. These initial efforts would not require construction activities or bringing in materials from offsite other than materials necessary for general land maintenance. Stage 1 Stage 1 of the implementation of the Conservancy Master Plan would be constructed simultaneously with Phase I of the Campus construction. FASNY commits to providing the three (3) small gravel parking areas, enhanced maintenance and security, entry features and signage, outdoor classrooms, FASNY gardens, and maintenance of existing golf cart paths as walking trails with additional mowed paths within the Conservancy as part of Phase I. FASNY would also remove invasive species and introduce native species in former fairways and greens. A Conservancy steward would be also retained by FASNY and would coordinate restoration of the habitat areas in alignment with FASNY s educational mission. Stage 2 FASNY intends to implement the following aspirational elements of the Conservancy as funding becomes available: habitat restoration, wetland restoration, stream restoration, propagation greenhouse, community garden, seating areas, shade structures and storage sheds, rehabilitated bathrooms, observation deck and floating pier, and woodland boardwalk and outlook within the Conservancy as funding becomes available. It should be noted that the ultimate realization of certain of the elements shown in the Master Plan would also be dependent on the natural progression of ecological functions and growth cycles of plant materials.

11 CONSTRUCTION MANAGEMENT PROTOCOL REQUIREMENTS FASNY will seek to limit construction related impacts on the Project Site, and to surrounding properties, by including the following restrictions in the Construction Management Plan: Hours of operation of construction vehicles and construction work on the site. - Per the City of White Plains Municipal Code, Chapter 3-4, Noise Pollution, construction activities shall occur only between the hours of 7:00 AM and 7:00 PM on weekdays, and between the hours of 9:00 AM and 7:00 PM on Saturdays. Hours of deliveries to the site, location of deliveries. - Per the City of White Plains Municipal Code, Chapter 3-4, Noise Pollution, loading or unloading of vehicles shall occur only between the hours of 8:00 AM and 10:00 PM on any day of the week. It is anticipated, however, that deliveries will typically occur between 7:00AM and 7:00PM on weekdays and Saturdays. - During construction, deliveries will be made to designated staging areas on-site. Access to the site will be via designated stabilized construction entrances whenever possible. Requirement for loading/unloading and storage of materials on the Project Site. - Loading, unloading, and the storage of materials on the Project Site will be in designated staging areas on-site, whenever possible. Length of time travel lanes can be encumbered. - The Construction Management Plan prohibits staging or "waiting" by construction vehicles on City streets, unless previously approved by the Commissioners of Public Works and Public Safety. All encumbrances on public streets, highways or sidewalks shall be in conformance with the City of White Plains Municipal Code, Chapter 7-3, Article IV, Obstructions. - Proposed improvements within the right-of-way of Ridgeway and Hathaway Lane will be performed in accordance with the requirements of the City of White Plains. The construction sequence of the Project must be coordinated with the City s Department of Public Works before it can issue permits to close streets or sidewalks. All lane closures will also be coordinated with the City of White Plains Department of Public Safety, Police Bureau. Sidewalk closing or pedestrian diversions to ensure the safety of the pedestrians. - Any work to be performed on public sidewalks shall be in conformance with the City of White Plains Municipal Code, Chapter 7-3, Article IV, Obstructions, and shall include appropriate measures to ensure the safety of pedestrians. Controls on "fugitive dust." - Requirements for dust control are included in the Project s Site Sediment & Erosion Control Plans and as part of the Stormwater Pollution Prevention Plan (SWPPP) prepared for the Project. These requirements are the responsibility of FASNY s contractor in the Construction Management Plan prepared for the Project. These plans for the protection of adjacent properties must prove satisfactory to the Commissioner of Buildings, Commissioner of Public Works and the Environmental Officer prior to the commencement of construction. Page 9 of 11

12 The impact of run-off from the Site on the City storm drain system, such as from the wash down of delivery vehicles departing the site, shall be minimized. All such vehicles must be cleaned on pads located on the Site and all drainage must have proper filtration of the wash-down water. - The impacts of run-off from the site during and after construction have been addressed in the Project s Site Sediment & Erosion Control Plans and as part of the Stormwater Pollution Prevention Plan (SWPPP) prepared for the Project. The Construction Management Plan specifically requires that construction vehicles and equipment, including delivery vehicles, be rinsed on-site in specifically designated areas. - Included on the Site Plans is a note about soil and erosion control regulations and the need to comply with applicable City of White Plains and New York State Department of Environmental Conservation regulations, including the requirement for a SWPPP. Noise. - All work, including but not limited to the erection, construction (including excavating), demolition, alteration or repair of any building or structure, the operation of any machinery, commercial motor vehicle, equipment, pump, or similar mechanical device, the loading or unloading of vehicles, or deliveries shall be performed in accordance with the City of White Plains Municipal Code, Chapter 3-4, Noise Pollution. Additionally, both noise impacts and air quality impacts of construction equipment will be minimized as follows: i. The internal combustion engine-powered construction equipment used in the construction of the Project must be limited to late model (1998 and newer) so as to take advantage of the cleaner burning engines. Also, these off-road pieces of equipment will have better sound attenuation properties. Exceptions to this are subject to the approval of the Commissioner of Building upon a demonstration that it is not feasible or practicable to obtain the required equipment. Unless an exception is granted by the Commissioner of Building, no engines are to be used unless "critical" level exhaust silencers are fitted. This is the quietest of the three main categories and is consistent with what the City uses for its own fleet. ii. All non-road vehicles over 50HP used with regard to the Project are to utilize the best technology available for reducing the emission of pollutants, including, but not limited to, retrofitting such non-road vehicles with oxidation catalysts, particulate filters, and/or technology with comparable or better effectiveness. All construction equipment is to include PM2.5 emission controls. iii. All diesel powered non-road vehicles in use at the construction site are to be fueled only with ultra-low sulfur diesel having a sulfur content of no more than fifteen (15) parts per million. All fuel delivered for use at the construction site shall consist of said fuel. - FASNY will take all appropriate steps to avoid vibration impacts to adjacent properties, including use of procedures approved by the Departments of Public Safety and Building for rock chipping if any is to be conducted (not anticipated for the Proposed Project), pile driving (not anticipated for the Proposed Project), sheeting and shoring around the excavation area, and any such other necessary protections as are deemed appropriate and protective of the adjoining properties by the Commissioner of Building. If blasting is required, separate approval must be obtained from the City departments of Building, Public Safety and Public Works. It should be noted that the Proposed Project is not proposing any blasting activity. Page 10 of 11

13 Pest control. - The construction documents and specifications for the Project will include appropriate pest control measures to be employed by FASNY s contractor, particularly with regard to excavation and demolition of existing structures. The work will be performed in accordance with all applicable requirements of the City of White Plains. Street cleaning. - Requirements for maintaining surrounding streets clean of dirt and debris are included in the project s Site Sediment & Erosion Control Plans. These requirements are the responsibility of FASNY s contractor as stated in the Construction Management Plan prepared for the Project. Site security. - FASNY and its contractor(s) will develop a plan for appropriate security measures to be employed on-site during construction to ensure that areas of the Site that pose a risk to unauthorized individuals are inaccessible. Schedule of periodic meetings with nearby residents and City staff to coordinate project construction and keep residents advised. - FASNY will work with the City of White Plains and surrounding neighborhoods to schedule periodic meetings to inform the City and neighbors of scheduled project construction and anticipated neighborhood impacts. - FASNY will coordinate a public outreach plan that would provide on-going information about the status of construction activities and the anticipated schedule of construction activities. - FASNY will provide one or more methods for communication (e.g., telephone number, address) for use by neighbors and/or the City of White Plains to communicate any concerns or observations during the construction period. FASNY will share any communications received using these channels with City of White Plains officials and will coordinate with the City of White Plains on the appropriate response to the issue(s) raised.
