SCHOOL DISTRICT Prior to the commencement of demolition or construction activities for the Project, the Construction Manager (CM) shall coordinate with the School District to discuss the construction project. The School District shall inform the CM of anticipated construction or other special activities on MS/HS site for purposes of coordinating activities. The School District shall identify critical testing days/times so that the Owner can avoid the most noise- intensive activities during those times. 2.2. ARBORS Prior to the commencement of demolition or construction activities for the Project, the CM shall photo and/or video document the physical condition of Arbor Drive from its intersection with King Street to the southwestern property line of the Project Site. This documentation shall be provided to the Village and to the Arbors. During construction, the CM designate a single point of contact (whose contact information shall be shared with the Village and the Arbors) who shall be responsible to monitor the condition of Arbor Drive and make repairs as warranted and appropriate, as determined by the Village. At the conclusion of construction, the Applicant shall resurface Arbor Drive from King Street to the southwest corner of the Project Site. 2.3. LOOK AHEAD Prior to the commencement of demolition or construction activities for the Project, and at least every two weeks thereafter, the CM shall send to the Village, the School District, and the Arbors a two-week “look ahead,” identifying the anticipated significant construction activities during that period, especially those that have the potential to be noise intensive. 2.4. UTILITY NOTIFICATION Prior to the commencement of demolition or construction activities for the Project, the CM shall notify contacts for each subsurface utility provider adjacent to the Project Site. The CM shall report to the Village on the notifications as well as any material feedback received from the utility providers. 3. CONSTRUCTION PHASING AND SEQUENCING The narrative in this section should be read in conjunction with the Construction Phasing and Staging Plans developed by A.P. Construction and appended hereto, as well as Sheet C-110 to Sheet C-205 of the engineering plans. 3.1. PHASING & SEQUENCING SUMMARY Construction of the Project is anticipated to be completed in approximately 30 months and is expected to occur in approximately seven phases. Construction would begin with the installation of silt fencing, disconnection of utilities, demolition of the existing Site building, asphalt and tree removal, and expansion of the detention pond. There will be no removal of asphalt outside of the existing building footprint until the entire building has been demolished and the footprint of the demolished building has been stabilized. This phase is anticipated to take approximately 3 months. Once the building is demolished, road and Site utilities work would start, the garage foundation would be constructed, and the northern wings of the IL building would begin construction. 900 King Street Site Plan Application 07/23/2021 4 DRAFT Construction of the proposed buildings would be separated into four phases with overlapping construction times: AL facility (construction would last approximately 14 months), IL center core (construction would last approximately 23 months), IL south wings (construction would last approximately 14 months), and townhouses (construction would last approximately 14 months). The final phase is the Site restoration phase, which would take place at the end of the building construction and is expected to last approximately two months. Approximately 38,158 cubic yards of earthen cut material, and approximately 36,686 cubic yards of earthen fill material would be required, resulting in approximately 1,472 cubic yards of material exported from the Site by truck. 3.2. SITE SAFETY During construction, the Site would be fenced off to ensure safety from construction activities. The pedestrian path leading from the Village buildings to Harkness Park and the Blind Brook High School would be temporarily closed. A sign would be placed at the general location of this path, as well as posted on the construction period noise wall, directing students and other pedestrians to the existing sidewalk along King Street, where they would cross Arbor Drive at the existing signalized crosswalk, continue through the park or along King Street. At the end of the construction period, the pedestrian path on the Project Site would be restored and enhanced and would be re-opened to the public. 3.3. ABATEMENT ACTIVITIES Interior abatement activities related to ACM, lead-based paint, older equipment that may contain mercury, PCBs, or other regulated material shall be completed prior to building demolition and disturbance of the existing slab. Prior to demolition surveys for asbestos-containing materials (ACM) and other regulated building materials would be conducted throughout the existing structure. ACM would be removed prior to demolition by a licensed asbestos abatement contractor in accordance with applicable regulatory requirements. As required by the Environmental Findings Statement (EFS) adopted by the Board of Trustees, the Village shall be provided with a copy of the ACM surveys as well as copies of agency correspondence related to abatement filings describing abatement work within 45 days of completion. Demolition shall occur in accordance with applicable regulations (e.g., OSHA and NYSDOL), as well as in accordance with Village approvals. 3.4. OTHER DEMOLITION REQUIREMENTS  Prior to the commencement of demolition, the CM shall provide to the Village a list of potential transporters and recycling/ disposal facilities that will accept demolition materials  Within 30 days of the completion of work, the CM shall provide to the Village an inventory of demolition materials/ types, including abated materials, together with the quantities removed and the off-site destinations and disposal/ recycling documentation. 4. CONSTRUCTION PERIOD TRAFFIC The following policies and procedures shall be implemented during construction to minimize adverse traffic impacts from construction  Adequate on-site parking for construction workers shall be provided throughout the construction process. Construction Management Plan DRAFT 5 07/23/2021  No construction worker vehicles shall be permitted to park, pick-up, drop-off, or otherwise stand on Arbor Drive.  Construction Trucks shall use major roads (i.e., I-287; I-95; I-684) to reach the Project Site.  To the extent practical, construction truck trips shall be scheduled so as not to coincide with the peak entry and exit hours of the MS/HS.  Adequate on-Site areas for the queuing, staging, loading, and unloading of vehicles shall be provided throughout the construction process.  No construction trucks, including those related to the delivery of equipment or materials, shall queue, load, un-load, park, or otherwise stand on Arbor Drive. 5. MATERIALS MANAGEMENT PLAN The EFS requires that the Materials Management Plan (“MMP”) “be prepared by the Applicant prior to the start of excavation or ground disturbing activities.” As the MMP is a technical workplan, which includes information based on the final approved site plan and any conditions thereof, it cannot be finalized prior to Site Plan approval. The Applicant understands that any Site Plan approval for the Project will be conditioned on the preparation of an MMP consistent with the EFS. Further, the Applicant understands that demolition and construction permits will not be issued until completion of the MMP. It is noted that the MMP will include the measures outlined in §M.2.a of the EFS related to soil handling and contingency measures to be implemented if unknown soil conditions are encountered. As required by §B.1.b of the EFS, the MMP will also reiterate that, “No blasting or rock crushing shall be permitted without further review and approval by the Village Building Inspector.” Upon completion, and prior to demolition or construction, the MMP will be appended to this CMP. 6. EROSION AND SEDIMENT CONTROL An Erosion and Sediment Control Plan shall be implemented in accordance with NYSDEC regulations. The Plan is illustrated and described in the Stormwater Pollution Prevention Plan (“SWPPP”) accompanying the Site Plan Application. The final, approved plan shall be appended to this CMP. 7. FUGITIVE DUST AVOIDANCE PLAN In order to minimize potential air quality impacts associated with construction and demolition activities, the following policies and procedures shall be implemented during construction:  Minimizing the area of soil that is disturbed at any one time;  Minimizing the amount of time during which soils are exposed;  Installing truck mats or anti-tracking pads at egress points to clean the trucks’ tires prior to leaving the Project Site;  Watering of exposed areas during dry periods. Dust suppression activities would not be expected to generate standing or flowing water.;  Using drainage diversion methods (e.g., silt fences) to minimize soil erosion during Site grading;  Covering stored materials with a tarp to reduce windborne dust;  Limiting on-Site construction vehicle speed to 5 mph; and  Using truck covers/tarp rollers that fully cover hauled materials and keep debris and dust from being expelled from the truck along its haul route. 900 King Street Site Plan Application 07/23/2021 6 DRAFT As required by the EFS, in the event that airborne dust from the Project Site creates an adverse impact to the MS/HS, the School District shall notify the CM and the Village immediately. The CM shall take appropriate measures to ameliorate the temporary impact. The CM, Village, and the Village’s Special Engineering Consultant shall, after the immediate situation is resolved, discuss the incident to determine its cause and steps that can be taken to avoid future impacts. On-site visual monitoring of dust conditions will be performed to identify potential adverse air quality impacts from airborne dust and, potentially, the need to implement a Community Air Monitoring Plan (“CAMP”). Should visual inspection of actual emission and dust conditions during construction warrant, as determined necessary by the Village’s Special Engineering Consultant, a CAMP shall be implemented. The procedures for a CAMP are included in the Materials Management Plan. 8. DIESEL EMISSION CONTROL PLAN In order to minimize potential impacts from diesel emissions related to construction equipment and vehicles, the following policies and procedures shall be implemented:  Ultra-low sulfur diesel would be utilized for all construction equipment and vehicles.  All equipment would be properly maintained.  Idling of construction or delivery vehicles or other equipment would not be allowed when the equipment is not in active use.  Construction trucks would not be allowed to idle.  Use of Best Available Tailpipe (BAT) Reduction Technologies. Non-road diesel engines with a power rating of 50 hp or greater and controlled truck fleets (i.e., truck fleets under long-term contract with the project) including but not limited to concrete mixing and pumping trucks would utilize BAT technology for reducing diesel particulate matter (DPM) emissions. Diesel particulate filters (DPFs) have been identified as being the tailpipe technology currently proven to have the highest reduction capability. Construction contracts shall specify that all diesel nonroad engines rated at 50 hp or greater would utilize DPFs, either installed by the original equipment manufacturer or retrofitted. Retrofitted DPFs must be verified by EPA or the California Air Resources Board. Active DPFs or other technologies proven to achieve an equivalent reduction may also be used. 9. VIBRATION MONITORING PLAN The Owner shall implement a Vibration Monitoring Program (“VMP”) during demolition of the existing building, subsurface construction activities, and activities involving the use of construction impact devices (such as jackhammers, pavement breakers, pile drivers, pneumatic tools, etc.) on the Project Site. Specifically, the VMP will monitor subsurface vibration levels proximate to the Arbors and the Tennessee Gas Pipeline. The precise monitoring locations will be determined by the Owner in consultation with the Project Engineer and Vibration Consultant and shall be subject to review and approval of the Village’s Special Engineering Consultant. The VMP shall contain the following elements:  Baseline vibration monitoring for two weeks prior to the start of demolition.  Continuous vibration monitoring at one location proximate to the Arbors and one location proximate to the Tennessee Gas pipeline. Vibration monitoring shall be conducted using a seismograph with a velocity transducer capable of measuring vibration on three mutually perpendicular axes. The seismograph will include a wireless modem and will be configured to have a warning trigger level of 0.3 inches/second and permissible threshold level of 0.5 inches/second, consistent with federal guidance on the protection of structures Construction Management Plan DRAFT 7 07/23/2021 from construction vibration. In the event of construction-induced vibration exceeding either threshold level, an email alert will be sent to the CM and the Owner’s Vibration Consultant. In the event that the permissible threshold is exceeded as a result of construction activity, the construction activity producing the vibration would be stopped until an alternative method can be implemented that does not result in exceedances of the permissible threshold. The Owner’s Vibration Consultant shall prepare and circulate to the Owner, CM, Village, and Village Special Engineering Consultant monthly reports summarizing the vibration monitoring results. The reports will include an executive summary of vibration levels at each monitoring location, and detailed vibration data at each monitoring location throughout each workday during the monitoring period. 10. CONSTRUCTION PERIOD NOISE MITIGATION PLAN 10.1. PHYSICAL NOISE MITIGATION 10.1.1. Arbor Drive A 12-foot tall construction period noise barrier will be installed on the Project Site along its Arbor Drive frontage extending southwest from the Main Site Driveway to the point at which the barrier turns toward the north. The barrier will be constructed from plywood, or a material of similar noise abatement properties, and shall be installed prior to the start of significant construction activities during the time that the MS/HS is in session during the normal school year and maintained throughout demolition and construction activities. Gates in the barrier to provide authorized access to the construction site shall be closed at all times except when needed for access/egress. Given the visual prominence of the noise barrier, the Owner shall take measures to make the barrier more aesthetically pleasing than a “plain” plywood wall. Upon installation, the barrier will be painted green. Subsequent to the construction of the barrier, the Applicant will install a “faux ivy,” or similar three dimensional product, covering on the exterior of the noise barrier. 10.1.2. Southwest & Northeast – Facing Arbors HOA & Village Hall Pursuant to the EFS, the Arbors HOA and the Village Hall sides of the property shall be improved with a construction period noise barrier constructed of plywood, or a material of similar noise abatement properties. This barrier shall be painted green upon its installation. Consistent with the EFS, and to determine the appropriate height of the noise barrier, an supplemental acoustical analysis was performed (see attached May 24, 2021 letter from AKRF, Inc.). The analysis was conducted using a three-dimensional noise modeling software, “CadnaA,” which is a state-of-the-art tool for noise analysis. Geographic data associated with the site work, adjacent building footprints and heights, and the location and elevation of other improvements were input into the software. For each construction phase various data, including construction equipment, location, noise emissions and duration of use, was also input.1 1 The construction-period data used in this analysis is significantly more detailed than the data utilized in the FEIS, given the progression of construction planning subsequent to approval of the PUD Master Plan. Whereas the FEIS included conservative estimates of noise generation and equipment location given the lack of specific details available regarding equipment types and location, the current analysis made use of more fine-grained 900 King Street Site Plan Application 07/23/2021 8 DRAFT The refined acoustical analysis indicated that a 12-foot tall noise barrier along the Arbors and Village Hall portions of the Project Site would provide minimal, or no, additional noise reduction compared to a condition in which no barrier was located on those sides of the Site.2 There are a few likely reasons for this result. Noise barriers are most effective for reducing noise at receptors within approximately 50 feet of the barrier if the noise source, e.g., trucks, excavators, etc., are within a comparably small distance to the noise barrier. Most equipment used during construction of the Project would operate farther from the barrier for a majority of the construction period. Consequently, the benefit of the barrier is reduced as the distances between source and barrier or receptor and barrier increase. Additionally, benefit from utilizing barriers is minimized in part due to existing characteristics of the area, including topography, which sets construction noise sources at a higher elevation thereby reducing the effective height of surrounding barriers, as well as moderate to high existing noise levels at some nearby noise receptors. Based on this analysis, and in accordance with the EFS, in addition to the 12-foot tall barrier along the Site’s Arbor Drive frontage, the Applicant will construct a 6- foot plywood barrier along the Arbors and Village Hall portions of the Site. The barrier shall be constructed prior to site demolition and maintained throughout construction. The location of the noise barriers are shown on Sheet C-200. 10.2. SITE LAYOUT AND POLICY-BASED NOISE MITIGATION The following measures are included in the construction staging plans or will be otherwise implemented during construction and demolition to minimize off-Site noise impacts.  Noisy construction equipment, such as cranes, concrete pumps, concrete trucks, and delivery trucks, would be located away from, and shielded from, sensitive receptors, such as the MS/HS, to the extent practicable;  Construction equipment, including the mufflers on the equipment, shall be properly maintained;  Electrification of construction equipment to the extent feasible and practicable will be undertaken as soon in the construction process as logistics allow;  The construction site is configured to minimize back-up alarm noise to the extent feasible and practicable;  Construction trucks shall not idle;  The hours of operation during construction shall comply with the time of day and day of week requirements of Chapter 158 of the Village Code;  Pile driving, jack hammering, blasting, and rock crushing shall not be permitted absent further review by the Village. site logistics details. It should be noted that this supplementary analysis does not supersede the FEIS analysis; rather, it was conducted for a different purpose, as described above. 2 Additionally, the projected noise levels with only the 12-foot tall barrier along Arbor Drive were comparable to, or less than, the levels predicted by the FEIS construction noise analysis. This is due in large part to the more refined analysis that was possible. Construction Management Plan DRAFT 9 07/23/2021 10.3. CONSTRUCTION PERIOD NOISE MONITORING Pursuant to the EFS, the Village may require the Owner to provide in-field noise level readings upon request, if warranted based on site work activities. These measurements would be compared to the noise levels modeled and reported in the FEIS and any supplementary noise modeling conducted to support the noise barrier design. Existing condition noise level monitoring shall be conducted by the Applicant for purposes of establishing baseline noise levels absent construction. The scope and schedule of this monitoring shall be coordinated with the Village’s Building Department.
