A. INTRODUCTION

The Noise Technical Report supplements the Design Report/Draft Environmental Impact Statement/Draft Section 4(f) Evaluation prepared for the Route 347 Safety and Mobility Improvement Project fromNorthern State Parkway in Smithtown to Route 25A in Brookhaven, Suffolk County, New York. The NY Route 347 Project involves the reconstruction of the 24-kilometer (15-mile) highway from the Northern State Parkway to Route 25A, including new on/off ramps on Northern State Parkway at New Highway, to improve traffic safety and mobility. The work includes roadway widening, interchange construction, retaining walls, and new traffic signals with interconnections. Bridge construction is planned for westbound NY Route 454 over NY Route 347 (as an alternative to retaining the at-grade intersection), NY Route 25 (Middle Country Road) over NY Route 347, and NY Route 347 over Nicolls Road (CR 97).

The proposed improvements to NY Route 347 constitute a Type I project according to 23 CFR 772, which is eligible for noise abatement should noise impacts occur. A noise study was conducted pursuant to Federal Highway Administration (FHWA) and NYSDOT guidelines to determine if noise receptors located on developed land (including residential and non-residential) would be impacted by the increased traffic noise associated with the project. For impacted receptors, abatement measures were evaluated and then tested for feasibility and reasonableness. The study included the following tasks:

� Identify existing land uses and activities within the study area;� Determine existing noise levels;� Predict what the future design-year noise levels would be if the project were built (Build

Alternative) and if it were not built (No-Build Alternative);� Compare future design-year noise levels (Build and No-Build) with existing levels and with

FHWA noise abatement criteria to determine traffic noise impacts;� Investigate various types of noise abatement that might be used to reduce or eliminate traffic

noise impacts if the project is built; and,� Identify noise-impacted areas for which noise abatement is feasible and reasonable.

B. BACKGROUND INFORMATION

Environmental noise is defined as the sound in a community emanating from man-made sources such as automobiles, trucks, buses, aircraft, trains, and fixed industrial sources or natural sources such as animals and wind. Sound levels are measured in logarithmic units called decibels (dB). An overall measurement of sound results in a single decibel value that describes the sound environment, taking all frequencies (pitches) into account. The human ear, however, does not sense all frequencies in the same manner. The “A”-weighted scale (expressed in dBA units) was developed to closely approximate the human sensory response from highway-related noise. The descriptor used to express noise levels for project assessment purposes is the equivalent noise level, Leq. The Leq is the logarithmic average of the varying sound levels during a defined period of time, normally one hour.

Under normal conditions, a change of three decibels is required for the average person to perceive a difference in noise levels without the use of instruments. Examples of the magnitude of individual change in traffic volume, traffic speed, or distance from the noise source to the receptor necessary to result in a 3 dBA change are:

� a doubling of hourly traffic volumes, with no change in speed,� a change in vehicular speeds of 15 miles per hour, with no change in volume, or� a one-third to one-half reduction in the distance between traffic and receptor.



Public reaction to noise levels is a function of location (urban, suburban, rural), time of day, fluctuation of noise levels, duration, and individual judgment of the listener. Usually, a decrease of 10 decibels appears to the listener to be a halving of the noise, while an increase of 10 decibels appears to be a doubling of the noise. For reference and orientation to the decibel scale, representative environmental noises and their respective dBA levels are shown in Table 1.

C. NOISE ABATEMENT CRITERIA

Noise Abatement Criteria (NAC) shown in Table 2 has been established by the FHWA to identify noise impacts from highway projects. Developed from research data, they represent acceptable maximumdesirable noise levels for various land uses and associated human activities.

Federal regulation 23 CFR 772 states that: “Noise impacts occur when the predicted traffic noise levels approach or exceed the noise abatement criteria levels, or when the predicted traffic noise levels substantially exceed the existing noise levels”. “Approach” is defined as 1 dBA less than the NAC. The FHWA has left the definition of substantial increase to the states. NYSDOT has defined a substantial impact as increases of 6 dBA or more. Both the “approach” level and the incremental 6 dBA criteria were used to assess the noise impact of the project.

2. Noise Measurement Program

Long-term, or 16-hour, monitoring was performed to examine the characteristics of the existing noise. Three locations were selected to cover the western (Site 1), central (Site 2), and eastern (Site 3) portions of the project area. These locations are shown on Maps 4, 7, and 14 in Exhibit A. Overall, the average hourly sound levels remain generally constant during the day and evening, with sound levels increasing around 5AM and decreasing around 11PM. During this period the sound levels are generally steady,



varying no more than 3 dBA at Sites 2 and 3, and 5 dBA at Site 1, and only begin to noticeably decrease after 11PM. Hourly readings are shown in Table 5.

3. Comparison of Noise Measurements to Modeled Sound Levels

To ensure accuracy of the use of the noise model, the traffic data collected during field measurements was entered into the model and the resulting modeled noise levels were compared with the measured noise levels. This was to ensure that changes between existing and future conditions were due solely to changes in roadway and/or traffic conditions and did not erroneously reflect discrepancies due to modeling input and measurement techniques. Generally, the difference between the measured and modeled traffic noise levels should be within 3 dBA. The measured sound levels as well as the modeled sound levels are shown in Table 6. For all of the measured sites, the model predicted traffic noise levels were within 3dBA of the measured traffic noise levels; indicating that the model may be used to accurately calculate traffic noise levels within the study area.

E. IMPACT ANALYSIS

To predict traffic noise levels at varying distances from the project roadway, a total of 1496 points wereinput into the model. These locations are shown on Maps 1 through 18 in Exhibit A.

In addition to changes in the roadway and distances between the roadway and receptor, traffic noise levels are heavily dependent upon traffic volumes, speed, and composition. Following is a description of the data that was used in the TNM model.



� Volumes – Existing (2004), No-Build (2035), and Build Alternative (2035) traffic volumes for Route 347 and the intersecting roadways were obtained from the traffic study discussed in Chapter III. The volumes for each roadway are provided in Table B-1 in Exhibit B.

� Speeds – Conservative (noisier) traffic speeds were used in the model - the highest speeds expected given the peak hour volume of traffic on the roadway. 50 mph was used for the mainline traffic on Route 347, and 25 mph was used for the intersecting local streets.

� Composition - The average composition that was observed for cars, medium trucks, and heavy trucks during the peak hour of the traffic data collection program was used to model the existing, no build and build conditions: 98% passenger vehicles, 1.2% medium trucks (typically 2 axles), and 0.8% heavy trucks (typically 3 or more axles). This composition mix was used for all roadways in the model.

1. Existing Conditions

Traffic volumes for 2004, with their associated speed and composition were entered into the model to yield predicted existing traffic noise levels. Existing modeled sound levels range between 50 and 74 dBA (Refer to Table C-1 in Exhibit C). Maps 1 through 18 in Exhibit A show the noise contour lines for 66 dBA and 71 dBA for the existing, no-build, and build conditions. Residences and parks within the 66 dBA contour line and commercial facilities with outdoor uses within the 71 dBA contour line would beconsidered to be above the Noise Abatement Criteria. A total of 442 properties would approach or exceed the Noise Abatement Criteria - 389 residences, 6 institutional facilities, and 47 non-residential/institutional facilities (Refer to Table 8).

2. No-Build Alternative

No-Build Alternative volumes for the year 2035 were entered into the model of the existing roadway to yield predicted traffic noise levels for the No-Build Alternative. No-Build modeled sound levels range between 50 and 75 dBA. A total of 479 properties would approach or exceed the Noise Abatement Criteria - 408 residences, 6 institutional facilities, and 65 non-residential/institutional facilities.

3. Build Alternative

Build volumes for the year 2035 were entered into the model and the design of the roadway was modified to reflect the proposed improvements to yield predicted traffic noise levels for the Build Alternative. The Build Alternative modeled sound levels range between 50 and 76 dBA. A total of 590 properties would approach or exceed the Noise Abatement Criteria - 491 residences, 6 institutional facilities, 1 park and 92 non-residential/institutional facilities.



F. NOISE ABATEMENT ANALYSIS

Possible noise abatement measures, as required by 23 CFR 772.13 (c)(1) include traffic management measures, alteration of the alignment, buffer zones, noise insulation, and noise barriers.

Traffic management measures which are effective in reducing traffic noise include prohibiting truck traffic or limiting trucks to specific hours, and reducing speed limits. Prohibiting truck traffic would negatively impact the commercial areas since Route NY 347 is a commercial roadway with businesses, to which trucks make regular deliveries. In order to achieve a noticeable reduction in noise from speeds, the speed limit would need to be decreased by approximately 33 kilometers per hour (20 mph). This reduction would inhibit traffic flow on the roadway and would not meet the project's goal of improving capacity, mobility and travel time reliability by developing an efficient highway improvement that provides congestion relief while maintaining existing traffic patterns.

Alteration of the alignment, either horizontally or vertically is an abatement technique; however, the design of the roadway is limited by the existing alignment, while also trying to minimize the number of displacements and takings of private property.

Buffer zones, which are undeveloped open spaces bordering a highway, would be very costly and disruptive to the community, as it would potentially require the taking of many dwelling units. To reduce the noise level by 10 dBA, a buffer zone would need to be 61 meters (200 feet) of undeveloped land.

Noise insulation of structures, which includes sealing windows, is only available to public schools.

Noise barriers are structures erected within the right-of-way, and can be either a vertical wall made of concrete, masonry, steel, or wood, or an earth berm. Noise barriers are the most common method to reduce or eliminate traffic noise impacts for several reasons: construction is limited to only where there is an impact, the goals of the project would not be compromised by slowing traffic or restricting access, and the noise levels at neighboring land uses would be reduced by 5 to 10 dBA, or more.

Noise barriers were considered for each noise sensitive area that would be impacted by the traffic noiseassociated with the project. However, the abatement measures need to be both feasible and reasonable.

According to the NYSDOT Noise Analysis Policy, to be feasible, the traffic noise barrier should strive for a reduction of 10 dBA or more, and must achieve a minimum of 7 dBA reduction in traffic noise at the location with the greatest reduction. Also included in feasibility is the continuity of a barrier. Largeopenings to accommodate land use access, cross streets, and maintenance access break the barrier, and allow noise to reach receptors unattenuated. A barrier requiring several breaks would likely not be able to obtain a substantial reduction in noise levels. In addition, as a rule of thumb, noise barriers are not usually analyzed or constructed for single residences.

For a traffic noise barrier to be reasonable, the cost per benefited receptor should be at or below the FHWA designated cost, which is currently $50,000. A receptor is considered to be benefited if there is a reduction of 5 dBA or more at a point where frequent human use occurs and a reduction in sound levelswould be beneficial. The cost of the barrier is determined by multiplying the surface area of the proposed barrier by $37.50 per square foot for reflective barriers, and by $46.50 per square foot for absorptive barriers. This total cost is then divided by the number of benefited receptors. If the cost per benefited receptor is $50,000 or less the barrier would be considered reasonable. However, this limit is subject to FHWA designation and may be raised in the future.



Fifty-nine noise barriers were studied to determine the feasibility and reasonableness of abating the traffic noise impacts. The barriers were then analyzed to determine if they could effectively reduce the traffic noise level at the impacted receptors, and then if the cost for each barrier was reasonable, given the number of residences that it would be predicted to benefit. Each of these barrier design options is described in Table 9 and shown on Maps 19 through 36 in Exhibit D.

The cost of the absorptive material for Barrier H7 was added to the cost of Barrier H9.

Should the conditions change substantially during the final design phase, the barriers may no longer be recommended and may not be included in the project’s contract plans. A final decision on the recommendations will be made upon completion of the project design and the public involvement processes.



H. PARALLEL BARRIER ANALYSIS

At several locations along the corridor, barriers are recommended to be placed on both sides of the road, parallel to each other. These barriers typically cause sound reflection between the barriers, increasing the sound levels from the roadway. When the distance between the barriers compared to the height of the barriers is less than or equal to 10:1, a parallel barrier analysis should be performed. The extent of degradation depends upon this ratio, as well as the relative height of the receiver in comparison to the roadway. The parallel barrier component of the TNM model calculates this degradation at each receiver.To minimize or remove the effect of the parallel barriers, sound absorptive barriers can be used either for one or both barriers. Table 11 shows the reduction in insertion loss that would occur with each type of barrier combination, no absorption on both sides, absorption on one side only (with an 85% noisereduction coefficient (NRC)), and absorption on both sides.

I. CONSTRUCTION NOISE

Construction of the Build Alternative would result in short-term, temporary construction noise along the length of the roadway. Noise produced during construction would vary, depending on such factors as the phase of construction and the type, quantity, and location of the equipment employed during that phase. Table 10 presents noise levels for types of construction equipment that could be used for the project.

Average noise levels for typical construction equipment, measured at 50 feet from the construction site, range from 76 dBA to 101 dBA. These sound levels would decrease at an approximate rate of 6 dBA each time the distance between the residence and the noise source is doubled, so at 100 feet, the sound levels would range between 70 dBA and 95 dBA. Construction activities would typically be limited to weekdays between 7 AM and 6 PM, except under special circumstances.

Construction of the bridges would most likely be the loudest, as they will likely require the use of pile drivers. Three specific locations which would likely require bridge construction were analyzed using the FHWA Roadway Construction Noise Model - the Route 454, Route 25, and Nicolls Road intersections. At Route 454, the closest residence is approximately 240 feet from the area proposed for pile driving. At Route 25 the closest residence is approximately 225 feet, and at Nicolls Road the closest residence is approximately 140 feet from the area proposed for pile driving. Assuming a maximum of two pile drivers operating at one time, as well as additional construction equipment, the total maximum sound level at the closest residences to Route 454 and Route 25 would be 88 dBA, and the closest residences at Nicolls Road would be 92 dBA. These high sound levels would be temporary in nature and should only occur at this level during operation of the pile drivers.

To minimize these levels, temporary abatement measures could be considered, such as portable or temporary noise barriers and equipment shields or enclosures. These measures could reduce sound levels by 5 to 10 dBA. The feasibility of these measures, as well as the possibility of erecting recommended barriers in the earlier phases of construction would be investigated during final design.
