This acoustic report has incorporated all items requested by the Town of Southold Planning Board during the DEIS scoping meetings and as issued in the Final Scope on April 5th, 2021. SoundSense collected existing sound level readings at the Project Site through noise monitoring performed from April 14th, 2021, through May 3rd, 2021, and May 13th through May 23rd, 2021, as well as the 20-minute readings collected in nearby areas around the Project Site on April 20th, 2021. These existing sound levels serve as the background sound levels for the area to be incorporated into all noise predictions completed for the project. The measured sound levels were used in conjunction with the traffic study provided by Dunn Engineering Services (“Traffic Study”), to assess any increases in traffic noise both during construction and after development of the project (“Build Condition”), as well as the equipment types and utilization factors provided by Red Rock Industries to develop a construction noise model. Any potential increases in sound levels at the receiving locations evaluated due to increased vehicle/truck passbys, construction activities, and final sound levels with the new development have been considered for the Project Site. Calculations were completed using SoundPLAN Version 8.2 (“SoundPLAN”) acoustic modelling software. Traffic calculations were completed using the Federal Highway Administration’s TNM 2.5 noise model inside SoundPLAN, and construction noise sources used standardized acoustic data available from the Federal Transportation Authority’s Transit Noise and Vibration Impact Assessment Manual published in 2018 (“FTA Guidelines”). A more detailed description of the methodologies used for the project can be found below in Section 3.6.5. Using the computer-generated model, an existing noise model for traffic was also developed for existing peak traffic generation. Along with the background sound levels collected, these baseline noise levels serve as the existing condition sound levels including the existing ambient and traffic levels (“Existing Condition”), to which the Build Condition predicted sound levels can be compared. This comparison allows for evaluation against the New York State Department of Environmental Conservation’s definitions regarding noise impact as well as the Town of Southold’s Noise Ordinance in Chapter 180 of the Town Code (“Noise Code”). While construction noise levels are predicted to have an impact at the nearby Residences, the Town of Southold specifically exempts construction noise from the requirements in the Noise Code. Nearby residences are predicted to be impacted by the construction for its duration, however impact from construction is common for any construction project to occur, whether it be commercial or residential, which is why it is commonly exempted from municipal noise codes. Traffic increases during construction and in the Build Condition, are not predicted to impact nearby residents through evaluation using TNM calculations. Furthermore, the Build Condition is not expected to increase existing sound levels by more than 4 dBA, which would constitute “No Impact” under the NYSDEC criteria. In addition to the proposed construction and development (“Proposed Plan”), an as of right development plan (“Alternate Site Plan”), was modeled based on the revised location and size of the development. Analysis showed sound levels are predicted to increase significantly during construction and that in the Build Condition there is no significant difference acoustically between the two plans. Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 4 of 94 3.6.1 EXECUTIVE SUMMARY (Continued): A proposed alternate truck route plan was also reviewed which diverts some of the trucks used during the excavation phases down Bergen Avenue on the return trip from the Project Site. Analysis showed that this reduced the impact of increased traffic noise levels at receivers along Cox Neck Road south of the intersection of Cox Neck Road and Bergen Avenue and was below NYSDOT recommendations at all receptors considered along Bergen Avenue and along Cox Neck Road south of the intersection of Cox Neck Road and Bergen Avenue.

Table 1 below summarizes the NYSDEC’s guidance provided in Section V, Subsection B, Item c. Table 1: NYSDEC Thresholds for Significant Sound Pressure Level (SPL) Increase Sound Level Increase (dB) Impact Need for Mitigation 0 – 3 No appreciable effect on receptors No need 3 – 6 Potential for adverse noise impact in cases where the most sensitive of receptors are present Mitigation may be needed for some sensitive receptors such as churches and theaters 6 – 10 Potential for adverse noise impact depending on existing SPL and character of surround land use and receptors Mitigation may be needed for most receptors, depending on existing conditions 10 or more Adverse impact Deserves consideration of avoidance and mitigation measures in most cases New York State Department of Transportation Noise Analysis Procedures and Project Environmental Guidelines The New York State Department of Transportation provides recommended criteria for road noise levels at various receptors in its technical report ‘NYSDOT Environmental Procedures Manual, Chapter 3.1’ released in August of 1998. It should be noted that the report notes that the sound levels outlined in this document are a criterion, and not a standard. It should also be noted that the criteria outlined in the document are guided towards future traffic after project completion. Recommended noise levels from Table 1 in the technical report can be found in Table 2. For the nearest receptors to the roads evaluated for additional traffic for this project, Category B is appropriate for evaluation. Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 6 of 94 SECTION 3.6.3 – ACOUSTIC CRITERIA AND DEFINITIONS (Continued): Acoustic Criteria (Continued) New York State Department of Transportation Noise Analysis Procedures and Project Environmental Guidelines Table 2: Recommended NYSDOT Criteria for Road Noise Levels Activity Category Leq(h) (dBA) L10(h) (dBA) Description of Activity Category A 57 (Exterior) 60 (Exterior) Lands on which serenity and quiet are of extraordinary significance and serve an important public need and where the preservation of those qualities is essential if the area is to continue to serve its intended purpose B 67 (Exterior) 70 (Exterior) Picnic areas, recreation areas, playgrounds, active sports areas, parks, residences, motels, hotels, schools, churches, libraries, and hospitals. C 72 (Exterior) 75 (Exterior) Developed lands, properties, or activities not included in Categories A or B above (e.g., commercial, industrial, other) D Undeveloped Lands E 52 (Interior) 55 (Interior) Residences, motels, hotels, public meeting rooms, schools, churches, libraries, hospitals, auditoriums, offices, etc. Definitions Ambient In this document ambient refers to the existing sound levels as collected during the noise monitoring performed at the Project Site from April 14th, 2021, through May 3rd, 2021, and May 13th through May 23rd, 2021, as well as the 20-minute readings at areas around the site collected on April 20th, 2021. Decibel (dB) Definition: The term used to identify ten times the common logarithm of the ratio of two like quantities proportional to power or energy. Thus, one decibel corresponds to a power ratio (10 to the 0.1 power) to the n power. Since the decibel expresses the ratio of two like quantities, it has no units. In this document, all decibels are presented using industry standard 20 µPa as the reference quantity. A-Weighting dBA – This weighting metric is commonly applied to sound pressure levels as it approximates the hearing response of the human ear which is more responsive to higher frequencies than lower frequencies. Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 7 of 94 SECTION 3.6.3 – ACOUSTIC CRITERIA AND DEFINITIONS (Continued): Definitions (Continued) Equivalent-Continuous Sound Level (Leq) Definition: Equivalent-continuous, frequency-weighted sound pressure level over a specified averaging time is the equivalent steady level, in that time interval, of the time-mean-square, frequency-weighted sound pressure produced by the sources of steady, fluctuating, intermittent, irregular, or impulsive sounds. The equivalent-continuous sound level of a time-varying sound is equal to the level of an equivalent steady sound at a measurement location for the same measurement duration. Specifically, Leq is 10 times the common logarithm of the ratio of the time-mean-square sound pressure 𝑜2(𝑡) over time period 𝑇= 𝑇2 −𝑇1 to the square of the standard reference sound pressure. Measured in dB the Leq is: 𝐿𝑒𝑞=10 ⋅𝑙𝑜𝑔10 (1 𝑇2 −𝑇1 ∫𝑜2(𝑡)⋅𝑑𝑡 𝑜𝑜2 𝑇2 𝑇1 ) Standards The information within this findings document is based on the ASTM Standards. Any variation to the ASTM criteria is based on additional research by such groups as the Acoustic Society of America and INCE that focuses on the well-being of humans in the presence of noise. Statistical Sound Levels (L10, L50, L90, etc.) The sound level that is exceeded for the percentage of time of that level during a period of time. Example: During a 1-hour measurement, an L10 of 60 dBA means the sound level was at or above 60 dBA for a total of 6 minutes, whereas an L90 of 60 dBA means the sound level was at or above 60 dBA for a total of 54 minutes. This is often used to demonstrate ambient sound levels. In addition to these sound levels, minimum and maximum sound levels measured are typically provided and denoted as Lmin and Lmax. Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 8 of 94 SECTION 3.6.4 – ANALYSIS OF EXISTING CONDITIONS: Ambient Noise Monitoring Results at the Project Site To establish the existing sound levels over longer periods of time, noise monitoring was performed at two locations at the Project Site. A marked copy of a satellite view indicating these locations can be found in Figure 1. Monitoring at Location 1 occurred from April 14th, 2021, to April 28th, 2021, and at Location 2 from April 28th, 2021, to May 3rd, 2021, and then from May 13th, 2021 until May 23rd, 2021 for a total of four full weeks of data collection. The disruption between May 3rd, 2021, and May 13th, 2021, was due to a disruption in data transmission from the noise monitoring unit. Therefore, additional days were completed after May 13th, to complete the four full weeks of data collection. Figure 1: Noise Monitoring Locations at the Project Site Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 9 of 94 SECTION 3.6.4 – ANALYSIS OF EXISTING CONDITIONS (Continued): Ambient Noise Monitoring Results at the Project Site (Continued) In addition to the collection of data, inclement weather can unnecessarily impact the data collected. To mitigate the impact of inclement weather, the data collected was compared to historical weather data from the nearest weather station at East Hampton Airport, since they maintain historical weather information. Any hour where precipitation was reported was eliminated from calculation of the metrics provided in Table 3, which serve as a summary of the acoustic data collected at each location for the daytime hours between 7 AM and 7 PM. This time range was selected because it is the same time range as the exemption for construction noise in the Noise Code. The median hourly Leq of 44 dBA was selected to use as the background sound level near the Project Site. This was the lowest median sound level collected during the measurements completed as seen in Table 3. This table summarizes the minimum, first quartile (statistic which 25% of the data is lower and 75% of the data is higher), the median (statistic which 50% of the data collected and 50% is higher), the third quartile (statistic which 75% of the data is lower and 25% of the data is higher), and the maximum. The individual graphs which summarize the sound levels by hour for each day of data collection can be found in Section 3.6.12. Dominant sounds at the Project Site include wildlife, nearby construction, and a couple examples of boat washing.

Acoustic readings were collected on April 20th, 2021, in the morning between 7:39 AM and 9:21 AM, and in the afternoon from 3:16 PM to 4:59 PM and were collected for a duration of 20 minutes each. Historical weather data from the nearest weather station on Long Island at East Hampton Airport reported winds between 3-8mph from the SSW during the morning readings with minimal cloud cover. The winds during this period can be described as a light or gentle breeze. The afternoon reading period had 16-18mph from the SW with minimal cloud cover. Air pressure was between 29.84-29.88 in. with 0 in. of precipitation. The winds during this period can be classified as a moderate breeze. Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 10 of 94 SECTION 3.6.4 – ANALYSIS OF EXISTING CONDITIONS (Continued): Twenty Minute Ambient Reading Results Around Project Site (Continued) The locations of acoustic readings collected can be found in Figure 2, while the results of the readings can be found in Table 4. Since the sound levels of vehicles passing were louder at the reading locations than they would be at the nearest residences, the L90 values have been used to represent the background sound levels at all receiver locations near each reading location. This was chosen because the acoustic readings were collected on the shoulder of West Mill Road and Cox Neck Road, meaning that vehicle passbys were significantly louder than what would be measured at the nearby residential structures. This provides a true definition of the background sound levels at each location without, or with minimal, vehicle passbys. For each location, the lowest L90 measured was used to represent a quieter background noise level and a worst-case scenario for noise impact.

Therefore, it does not provide a baseline for the Existing Condition as it does not provide a baseline considering the existing traffic to establish an Leq. To evaluate the Existing Condition, traffic data collected by Dunn Engineering were used to complete a traffic noise model in SoundPLAN using the FHA’s TNM 2.5 methodology. Incorporating traffic data into the calculation was completed so that the same calculation methodology and noise model is consistent when establishing the Existing Condition and future predictions. Additionally, this model allows for consistency in the baseline data for traffic generation so that all calculations are standardized for total trip generation. Inputs for existing trips were based on data provided by the traffic consultant. The traffic in the analysis varies throughout the day, as shown by the data. This time varying traffic was used for the analysis. The existing trips used for the analysis can be found in Section 3.6.11. The results of the baseline noise models can be found graphically in Figures 3-5 for the peak hour sound levels and Figures 6-8 for 8-hour sound levels. Overall sound pressure levels at each receiving location considered can be found in Table 5 for both peak hour and 8-hour levels. Receiving locations were selected by evaluating locations near the Project Site, as well as various receiving locations along West Mill Road and Cox Neck Road. These Existing Condition sound levels are used to evaluate the impacts of construction activities, traffic increases, and the Build Condition for evaluation.

SoundPlan constructs a 3D model for all areas analyzed by importing ground elevation data through Google Earth. Using the elevation data, SoundPlan constructs a 3D Digital Ground Model (“DGM”) of the terrain. Once the DGM is constructed, building height and location information, and roadway information can be imported using Open Street Map and added to the DGM. In addition, surface composition to calculate factors such as soft ground attenuation, reflections from buildings, and propagation over water are also calculated and assigned to the DGM. Depending on the specific situation analyzed, the DGM is updated to indicate changes in the elevation which would occur through the construction process, such as the excavation and retaining wall construction proposed (“Retaining Wall”). This ensures that the calculations are accurately completed for each phase of the project. An example of the DGM can be found in Figure 9, which shows the 3D model of the Retaining Wall construction phase. It should also be noted that all calculations completed for the project include frequency dependent data for accurate calculation of barrier effects/diffraction, although only overall sound pressure levels are presented at each receiving location to simplify the results and compare the results to the Town of Southold Noise Ordinance, NYSDEC Criteria and NYSDOT Criteria. Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 19 of 94 SECTION 3.6.5 – METHODOLOGY FOR ANALYSES (Continued): Development of SoundPlan 3D Model (Continued) Figure 9: DGM of Retaining Wall Construction Phase Development of Traffic Noise Model The traffic analysis is completed using TNM 2.5. The TNM noise model was used for evaluation of any traffic increase resulting from the Build Condition during construction, as well as vehicle traffic down the Haul Road. Additional trips for traffic generation as defined in the traffic study were added to the baseline trips presented in Section 3.6.11. Per the traffic study, three main traffic scenarios were considered for the project. These scenarios include Excavation Phases 1 and 2, Retaining Wall and Construction Phase Traffic, and Build Condition Traffic. Additional trips generated for the construction phases were used from the memo provided from Red Rock Industries, which noted the expected vehicles needed for each phase of construction. Additional trip generation in the Build Condition was provided in the traffic study completed. This additional trip generation data by phase and vehicle class can be found in Tables 6 and 7 for the various phases of the project. As noted in the construction details provided in the Red Rock Memo, the Haul Road will be used through the Retaining Wall Phase, and then is eliminated from the noise model starting at the Excavation Drainage Phase. Traffic data used to model the Haul Road during a peak hour are the peak traffic trips per hour all going down the Haul Road.

The dump truck was loaded with 39 tons of sand/dirt at the time of the readings, which is equivalent to 28-29 yards of material. This truck is Tier 4 compliant with EPA standards, using the latest technology to reduce environmental emissions. The applicant has mandated that all trucks on the project comply with the Tier 4 criteria. Readings collected during this testing included the truck passing at 35 mph, idle and backup with a white noise backup alarm, and release of the air brake. It should be noted that all contractors will be directed to disengage any Jake Brake system on incoming vehicles once they turn onto Cox Neck Road from County Route 48. These data are used in the analysis to demonstrate and to include sound levels from the backup alarm with engine idle, and air brake release on the construction site. The data collected have been converted into sound power levels and can be found in Table 8. In addition, calculated sound pressure levels 50’ from the source have also been provided as a reference. A more detailed copy of the reference data showing octave band sound power levels can be found in Table 27 located in Section 3.6.10. Any sound levels provided do not constitute a requirement for equipment used for the project but provide the basis for calculations completed.

Table 8 shows that the actual data collected by SoundSense of the dump truck collected would have a sound pressure level at 50 feet ranging from 62-73 dBA depending on the operating condition. This represents a significant reduction compared to the sound level in the FTA guidelines, showing that using the Tier 4 truck would represent a considerable reduction ranging from 11- 22 dBA. A 10 dBA reduction in sound level is typically heard as half of the original sound level and would constitute a significant reduction. It must also be noted that these reduced levels could not be used in the TNM calculations, but these reduced levels support that the TNM calculations completed would demonstrate a worst-case scenario for sound level increase due to traffic.

No blasting or pile driving is proposed as a portion of the construction. All construction equipment was then cross-referenced with data available from the FTA Guidelines to find standardized sound levels for construction equipment. Where information was not available within the FTA Guidelines, the integrated library within SoundPlan was utilized for equipment sound sources. Since the FTA Guidelines only provide sound data in overall A weighted sound pressure levels and do not provide frequency breakdowns of sound levels, data included for analogous equipment in SoundPlan was adjusted to meet the prescribed sound pressure level at 50’ as noted in the FTA Guidelines. Overall sound power levels for each piece of construction equipment broken down by each phase of construction, their quantities, and utilization factors, can be found in Tables 9-14 as provided by Red Rock Industries. A more detailed copy of the reference data noting frequency breakdown can be found in Table 27 located in Section 3.6.10. Any sound levels provided do not constitute a requirement for equipment used for the project but provide the basis for calculations completed. All predictions compiled for the construction noise analysis include a peak hour analysis with 100% utilization of all equipment to present a worst-case scenario coinciding with peak traffic generation, as well as an 8-hour Leq from 8 AM – 4 PM during the proposed construction hours to present an overall predicted daily average. The only exception to the 100% utilization in the peak hour is for any equipment which has a utilization factor of 10%, where the equipment was included for 48 minutes of that hour, accounting for 10% of an 8-hour day. It should be noted that some of these phases will occur together such as the Retaining Wall Phase to be completed while the Construction Phase is in progress, and the Excavation Drainage Phase while the Construction Phase is in progress. These phases and equipment types, quantities, and utilization factors have been included in the analysis.

The data provided in the UK Health and Safety Executive report only provides sound levels during wood chipping and is not representative of an hourly average. The highest sound power level identified was 124.5 dBA during wood chipping. To calculate a worst-case, but realistic sound power level over an hour, the 124.5 dBA was energy averaged with sources of 114 dBA for the Tub Grinder and 103 dBA for the Woodchipper based on wood chipping/grinding 50% of the time and idling only 50% of the time. This results in a sound power level of 122 dBA for both sources.

Noise sources considered in the Build Condition impact include a boat being washed, one male speaking at a “Loud” vocal effort level as defined by data presented in a technical report by the Environmental Protection Agency in 1977 titled Speech Levels in Various Noise Environments written by Karl S. Pearsons, Ricarda L. Bennett, and Sanford Fidell, two males speaking at a “Raised” vocal effort level, and the average acceleration of one truck, meant to simulate truck acceleration denoting moving boats in and out of storage. For evaluation of the Alternate Site Plan, the same sources were considered, but it should be noted that acceleration will likely need to be greater and occur for a longer period of time to pull one of the boats up the ramp to get to the Alternate Site Plan location at a higher elevation. Overall sound power levels for the sources considered can be found in Table 15 and additional information including noting frequency breakdown can be found in Table 27 located in Section 3.6.10. Any sound levels provided do not constitute a requirement for equipment used for the project but provide the basis for calculations completed.

An hourly peak Leq and 8-hour Leq were both calculated for each phase of the construction at the Project Site. These can be found in Figures 10-21 graphically show the results of these calculations at the Project Site. For the additional areas considered at West Mill Road/Cox Neck Road, and Cox Neck Road, the main noise source is traffic. Therefore, figures for these areas presented focus only on the Excavation 2 Phase and the Excavation Drainage Phase, as these were the loudest construction phases for each traffic condition. Figures 22-29 graphically show these results for the 8-hour Leq as well as the peak hour. Sound pressure levels for all evaluation scenarios and receivers can also be found in Tables 16 and 17 for the 8-hour and peak hour sound levels.

Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 48 of 94 SECTION 3.6.6 – POTENTIAL IMPACTS ANALYSIS (Continued): Construction Noise Impacts (Continued) While receivers near the Project Site are impacted by the construction noise, noise impacts due to construction are specifically exempt from the Noise Code. As can be seen from the figures and Tables 16 and 17, there is a significant increase at receivers R1-R16 for at least one phase of construction for either the peak hour or 8-hour Leq. For Receivers R1-R8, the increases are predominantly due to sound created at the Project Site from construction activities. These increases would have a significant impact as defined by the NYSDEC criteria to the nearby residences during the period of construction, with the highest levels during Excavation Phase 2. However, this noise would be limited to during daytime hours, and would be temporary since these increases are only during construction. For receivers R9-R18, any increase in the sound levels would be dependent on additional traffic, which is highest during the excavation phases. Sound levels are higher than recommended by the NYSDOT at receivers R10-R14 during the excavation phases, and during all construction at receivers R14 and R15. However, as noted in Section 3.6.3, the NYSDOT criteria are not standards, and these increases are temporary only during construction. All results presented are exterior sound levels. This impact is reduced to the interior of a nearby residence. As presented in the NYSDOT Environmental Procedures Manual, Chapter 3.1 published in August 1998, it is expected that a light frame building type with ordinary sash windows is expected to reduce sound levels by 20 dB. Should a storm window be used, this reduction is expected to increase to 25 dB. This 20-25 dB decrease in sound levels is expected to reduce the impact to the interior of residences and would minimize impact to quality of life while indoors. During the late fall/winter/early spring it is expected that most nearby residents will be primarily indoors during construction at those times, reducing the impact on quality of life. If the reduction of 20 dB is applied to the traffic data for receivers R10-R14, which exceed the outdoor recommendations from the NYSDOT, the interior recommendations in Category E of Table 2 for interior noise levels are met and would be within the NYSDOT recommended criteria for those receivers. Build Condition Impacts While construction noise would be temporary, Build Condition impacts are typically most critical under SEQRA review. The proposed project will be a storage facility. While the buildings will be largely inactive for a significant amount of the year, there will be times when boats are loaded into and out of the building. Due to the grading which will occur at the site, the retaining walls act as a sound barrier, largely containing the noise within the graded area. Figures 30-32 show the graphic presentation of the peak sound levels predicted at the Project Site using the noise sources presented previously in Table 15, as well as peak future traffic generation along Cox Neck Road and West Mill Road. Table 18 presents the overall sound pressure levels at each location.

NYSDEC evaluation criteria categorizes this as no impact and would not be expected to impact quality of life for any nearby residence. The greatest predicted increase would be 4 dBA at the Residence at Receiver R2. Furthermore, sound levels predicted also meet the conditions of the Noise Code at all receiving locations. The results of the analysis show that in the Build Condition that mitigation measures would not be required. Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 53 of 94 SECTION 3.6.7 – PROPOSED MITIGATION: As discussed previously, based on the results, there is no mitigation needed for the Build Condition scenario based on the results of the analysis. For the construction phases, a few mitigation measures have been integrated into the requirements for any contractor for the project. These requirements include the following measures: • Construction activities would be limited to Monday to Saturday from 7:00 AM to 7:00 PM in accordance with the Noise Code. No work would be completed on Federal or State holidays, or on Sundays. • In accordance with the Noise Code. Excavation phases would be limited from Monday to Friday from 7:00 AM to 5:00 PM. No work would be completed on Federal or State holidays, or on Sundays. • During construction phases, work on Saturdays and after 5:00 PM Monday to Friday will only include vehicle and machinery maintenance and planning. No work would be completed on Federal or State holidays, or on Sundays. • Any vehicle which requires the use of a back-up alarm will use a white noise back-up alarm instead of a single tone beep. • All trucks and drivers will be instructed to disengage all Jake Brake mechanisms once turning on to Cox Neck Rod from County Route 48. • All dump trucks utilized will be Tier 4 certified by EPA standards. These mitigation measures are critical to minimizing impact to nearby neighbors during the construction phases. It is well documented that tonal sounds are significantly more disturbing than sounds with a more distributed sound spectrum across all frequencies. While both the beeping backup alarm and tonal beep alarm are both OSHA compliant and have similar overall sound levels, the white noise alarm distributes the sound level over a wider range of frequencies so that the sound is less disturbing to nearby residents. Like the backup alarm, the Jake Brake mechanism on trucks causes a significant high frequency disturbance while trucks are moving through residential areas. In communication with Benimax Trucking, the company used to coordinate the in-situ readings of the Tier 4 dump trucks, it is understood that it is standard practice to disengage all Jake Brake mechanisms when driving through residential areas and is a requirement on nearly every project which the company takes on. Finally, while there is no standardized data available for sound levels on Tier 4 truck sound levels, the field testing and calculations in Section 3.6.5 show that a significant reduction in sound levels is predicted compared to standardized data from the FTA Guidelines. Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 54 of 94 SECTION 3.6.8 – REVIEW OF ALTERNATE TRUCK ROUTE: An alternate truck route has been proposed as mitigation of truck traffic. The alternate plan involves trucks during the excavation phases using Cox Neck Road to travel to the site, and then using Bergen Avenue access Sound Avenue when leaving the site. This alternate plan reduces the amount of truck traffic on Cox Neck Road south of the intersection between Cox Neck Road and Bergen Avenue. The revised routing is not proposed for additional traffic due to vehicle bringing in workers which would arrive at the beginning of the day and leave at the end of the day. As sources on Bergen Avenue were not considered in the Potential Impacts Analysis, additional acoustic data was collected along Bergen Avenue to quantify the existing ambient sound levels on August 2nd, 2022. Figure 33 below shows the location of the readings collected, noted as Location 5 and Table 19 provides the results of the acoustic readings collected. The afternoon L90 was used in the analysis as the ambient sound level Figure 33: Location 5 for Data Collection at Bergen Avenue Table 19: Results of Twenty Minute Acoustic Readings at Bergen Avenue Measurement Location Time Period LAeq (dBA) LASmax (dBA) L10 (dBA) L50 (dBA) L90 (dBA) LASmin (dBA) Location 5 7:39am – 7:59am 59 78 56 46 43 40 5:39pm – 5:59pm 65 87 54 42 41 40 Strong’s Yacht Center – 5780 West Mill Road – Mattituck, NY Acoustical Report – 11/29/22 Page 55 of 94 SECTION 3.6.8 – REVIEW OF ALTERNATE TRUCK ROUTE (Continued): To evaluate traffic, additional traffic distributions were needed to evaluate traffic down Bergen Avenue for both the Existing Conditions were needed. Reference data was provided from the traffic consultant and can be found from 8 AM – 4PM in Section 3.6.11. For additional trips, the additional trip generation data for Excavation Phases 1 and 2 were used as they represent the highest truck traffic during construction. However, the additional trip generation differs from that found in Tables 20 and 21 for peak hour and non-peak hour trip generation on Cox Neck Road and Bergen Avenue since trucks are not traveling twice down this road after leaving the Project Site and will instead be returning to Sound Avenue via Bergen Avenue. Table 20: Peak Hour Additional Trip Generation for Alternate Excavation Phase Vehicle Class Cox Neck Lane Bergen Avenue Automobiles 13 13 Medium Trucks 0 0 Heavy Trucks 5 5 Buses 0 0 Motorcycles 0 0 Table 21: Non-Peak Hour Additional Trip Generation for Alternate Excavation Phase Vehicle Class Cox Neck Lane Bergen Avenue Automobiles 0 0 Medium Trucks 0 0 Heavy Trucks 5 5 Buses 0 0 Motorcycles 0 0 Using the additional trip generation data, the TNM analyses in SoundPlan were completed for R15 – R18 for receivers on Cox Neck Road, and then for new receivers R19 – R24 for new receivers which were inserted into the model for Bergen Avenue. Using the results, the sound levels at R15 – R18 for the alternate truck plan were compared to the sound levels during Excavation Phase 1 to show the reduction in sound level. Table 22 shows the existing and predicted excavation phase peak hour Leq sound levels, while Table 23 shows the existing and predicted excavation phase 8-hour Leq sound levels at each location. Figures 34 and 35 show the graphic representations of the existing peak hour and 8-hour sound levels, respectively. Figures 36 and 37 show the graphic representation of the excavation phase peak hour and 8-hour Leq sound levels, respectively. As seen in the figures, there is a 1-2 dBA reduction in both peak hour and 8-hour sound levels, showing an improvement in sound levels at the locations along Cox Neck Road. Although there would now be an impact to receivers along Bergen Avenue, all predicted sound levels are lower than the NYSDOTs suggested criteria of 67 dBA at the receivers considered in the alternate plan.

This phase is anticipated to have the highest sound levels created once the excavation is complete and the two plans would be sufficiently different to compare. The same equipment utilizations, sound levels, and traffic generation were used for evaluation, with the only changes made being the location and grading to match the Alternate Site Plan. Figures 38 and 39 present the graphic representation of the data during construction for the peak hour sound level generation and 8-hour Leq sound levels predicted at the Project Site. Figures 40-43 show the predicted 8- hour Leq and peak hour sound levels at West Mill Road and Cox Neck Road. Tables 24 and 25 present the predicted sound levels for all receiving locations for the 8-hour Leq and peak hour Leq, respectively. Tables 24 and 25 also present the difference in predicted sound pressure levels for a direct comparison to the Proposed Plan. Results show that there would be an overall increase in sound level because the grade would no longer function as an acoustic barrier and would lose the transmission loss provided by the retaining wall. This is most evident at R4, where increases range from 4-5 dBA, as well as additional receivers which show a 1-3 dBA increase. It should be noted, that R6 shows a 2 dBA reduction in expected sound level with the alternate plan. However, all other receptors show either no difference, or an increase in sound levels during construction when the Alternate Site Plan is implemented.

The most considerable difference between the Proposed Plan and the Alternate Site Plan is the ramp which will need to be used to access the storage buildings. Vehicles using this ramp will need to accelerate more significantly to access the area, leading to increased sound generation. Figures 44-46 presents the graphic representation of the data, while Table 26 presents the predicted sound levels at all receivers. The Build Condition would still comply with the Noise Code and would have the same anticipated sound level except at R2 where the increase due to the Alternate Site Plan is only 1 dBA, which is not perceivable.
