NCCU Stat ion Refinement Supplemental Noise and Vibration Analysis

Durham-Orange Light Rail Transit Project | October 2016 | 1

1. IntroductionThis Durham-Orange Light Rail Transit (D-O LRT) Project Supplemental Noise and Vibration Analysis evaluates the potential noise and vibration impacts of the proposed North Carolina Central University (NCCU) Station Refinement (referred to herein as the NCCU Station Refinement). This analysis reviews the noise and vibration impacts previously disclosed for the D-O LRT Project in the D-O LRT Noise and Vibration Technical Report, Draft Environmental Impact Statement (DEIS), and the Combined Final Environmental Impact Statement (FEIS)/Record of Decision (ROD). These impacts are then compared to the impacts anticipated for the NCCU Station Refinement.

The NCCU Station Refinement includes the following changes and new information with the potential to affect adjacent noise and vibration receptors:

Reconfigured Alston Avenue Station and Park and Ride Lot: The original alignment terminatedon Pettigrew Street with a station west of Alston Avenue. The station’s parking deck included atotal of 980 spaces. The reconfigured alignment would pass Grant Street along Pettigrew Street,and veer south diagonally towards Alston Avenue and Highway 147. The new proposed AlstonAvenue Station would be located between Grant Street and Gillette Avenue, with approximately280 surface parking spaces. A new parking deck would be located on the southeast corner ofPettigrew Street and Alston Avenue with approximately 920 parking spaces.

Extension of the light rail alignment along South Alston Avenue to new NCCU Station at EastLawson Street: The refined alignment would leave the Alston Avenue Station, crossing overHighway 147 on aerial structure, with elevated track touching back to grade at the existingintersection of Linwood Avenue. The tracks would continue between the northbound andreconstructed southbound lanes until just north of East Lawson Street where it will terminate atthe NCCU Station between Dupree Street and East Lawson Street. Widening of Alston Avenue toaccommodate the light rail guideway will occur on the west side. Except for the aerial structure,the tracks will be constructed on a ballast base. The aerial structure will include direct fixationtracks on the structure’s deck.

2. Noise AnalysisThe noise analysis follows the same methodology presented in the D-O LRT Noise and Vibration Technical Report, which complies with the FTA Transit Noise and Vibration Impact Assessment, May 2006 (FTA guidance manual). The D-O LRT Noise and Vibration Technical Report evaluated the D-O LRT Project and project alternatives presented in the Draft Environmental Impact Statement (DEIS). The Combined FEIS/ROD provides a summary of impacts and mitigation commitments for the D-O LRT Project.

The track alignment plan and profile drawings for the NCCU Station Refinement were used to evaluate the proximity between the centerline of the proposed light rail track and the adjacent noise sensitive receptors. Noise sensitive receptor locations used to determine the distance of a receptor from the proposed transit facility are located at the closest usable space on the receptor property. The closest usable space is defined as the portion of a receptor property closest to the proposed transit facility where residents or property users would normally be impacted by noise and/or vibration. Where the proposed alignment change varies from the alignment disclosed in the Combined FEIS/ROD, the greatest shift in track alignment was used as a worst-case condition.



In addition to the proximity of the track alignment, other noise generating elements were considered in this noise analysis, including: increases in traffic near station park and ride lots, the introduction of new at-grade crossings, and the addition of other project elements like traction power substations and crossovers.

It is anticipated that the increased number of parking spaces and change in location of the park and ride garage would result in changes to traffic, which may increase noise levels. In addition, the operation of the train would introduce new sounds associated with the steel wheels operating on the rail, the sounding of bells before an at-grade crossing, and before entering the station. However, the use of horns in regular rail operations are not anticipated, as the light rail vehicles will only sound horns in emergency situations. For this reason, horns are not included in this analysis.

Finally, light rail vehicle specifications were assumed to include damped or resilient wheels such that noise from wheel squeal on tight radii curves would be minimized. Other elements that contribute to ground borne noise or vibration are discussed under the Vibration Analysis section of this document.

Figures 1 and 2 show the location of noise and vibration sensitive receptors, new noise monitoring locations, and impact areas from vibration and/or ground-borne noise.

2.1 September 2016 Noise Measurements

As shown in Figure 1, ambient noise measurements were performed at three representative locations along light rail alignment for the NCCU Station Refinement. These measurements were conducted on Tuesday September 13th and Wednesday September 14th 2016 using a Larson Davis 712 Type II sound level meter. Monitoring was conducted for approximately 20 minute periods at each site during the morning peak hours (6:30 a.m. to 8:00 a.m.), midday (11:30 a.m. to 1:00 p.m.), evening peak hours (5:00 p.m. to 6:30 p.m.), and late night (8:30 p.m. to 10:00 p.m.) periods during the week. Additional detail on the noise monitoring sites and the data collected is included in Appendix A of this report.

This information was then extrapolated to 1 hour for the Leq and to 24 hours for the Ldn equivalents. In order to compute the Ldn and ensure a conservative estimate, the lowest measurement from AM and PM measurements was used. Table 1 summarizes the results of the noise measurements and calculation of Ldn.

2.2 Reconfigured Alston Avenue Station and Park and Ride Lot

Under the proposed NCCU Station Refinement, the Alston Avenue Station and light rail alignment would shift from the location documented in the Combined FEIS/ROD on the north side of Pettigrew Street. Instead, the alignment would cross Pettigrew Street at-grade and diagonally east of Grant Street to run toward NC 147, west of the Alston Avenue NC 147 Bridge.



The reconfigured platform for the Alston Avenue Station would be located between Pettigrew Street and the Alston Avenue/NC 147 westbound on-ramp. Approximately 280 surface parking spaces would surround the station platform. Approximately 920 spaces of additional parking would be constructed in a new parking garage, which would be located in the southeast quadrant of Alston Avenue and Pettigrew Street.

The Alston Avenue station plan previously contained a parking garage, which would accommodate up to 980 parking spaces. This garage was originally proposed to be located within the footprint of the new surface parking and reconfigured station platform for the NCCU Station Refinement. However, the surface parking spaces would extend closer to the existing residential buildings on Colfax Street and Gillette Avenue than the garage location proposed under the Combined FEIS/ROD. Regardless of the park and ride configuration, it is not anticipated that the automobile traffic would differ from the existing traffic, and therefore traffic is not expected to be a significant source of noise.

2.3 Extension of light rail alignment along South Alston Avenue to new NCCU Station at East Lawson Street

South of the reconfigured Alston Avenue Station, the alignment will extend south to travel toward the proposed NCCU Station. The alignment will travel from the Alston Avenue Station and ascend on aerial structure to travel over NC 147 (including over the two highway ramps). The alignment will then begin to descend after the NC 147 off-ramp in order to enter the middle of South Alston Avenue. As the alignment descends, it will transition from retained fill to at-grade tracks near Linwood Avenue.

In order to construct the light rail in the middle of South Alston Avenue, the southbound lanes of South Alston Avenue will need to be reconstructed. The South Alston Avenue lanes will be reconstructed toward the west side to accommodate the center running light rail tracks and the new terminal station. The new terminal station, known as the NCCU station, will be located in the middle of South Alston Avenue between Dupree Street and East Lawson Street.

It is anticipated that all of the residential and commercial properties that front the west side of South Alston Avenue will need to be acquired in order to accommodate the construction of the light rail alignment, the reconstructed South Alston Avenue roadway, and the new NCCU station. As a result, the proposed light rail alignment will be located between 80-160 feet from remaining receptors on the west side of South Alston Avenue and 60-80 feet from the receptors on the east side of South Alston Avenue.

A new traction power substation and signal house are anticipated to be located between Price and Cox Avenues. In addition, it is anticipated that a double crossover will be located between the tracks, east of Price Avenue. It is anticipated that the TPSS and crossover will increase noise levels.

2.4 Summary

As shown in Table 2, the NCCU Station Refinement would not result in noise impacts to the surrounding community.

3. Vibration Impacts The receptors used in the noise analysis were evaluated for potential vibration and ground borne noise impacts. Based on the vibration screening criteria (FTA Transit Noise and Vibration Impact Assessment, 2006) Category 2 residential land uses within 150 feet of the source of vibration and Category 3 (churches) within 100 feet of the source of vibration have a potential for vibration impacts. All other receptors at farther distances do not have the potential for vibration impacts. As a result, none of the receptors in the vicinity of the Alston Station were included in the analysis, and five new receptors along South Alston Avenue were evaluated, as shown in Table 3.

The primary ground-borne noise and vibration inducing elements of the extended alignment along South Alston Avenue include the placement of crossover tracks between Price Avenue and Cox Avenue, which results in an increase of 10 vibration decibels (VdB). As was the case in the original analysis document in the D-O LRT Noise and Vibration Technical Report, efficient soils were assumed within the study area, which result in 10 additional VdB added to all receptors. Conversely, the elevated structure over Highway 147 results in a reduction of 10 VdB to adjacent receptors.

Where receptors showed that an impact from ground-borne noise or vibration would occur, further analysis was conducted to determine the extent of impacted areas. Figures 1 and 2 show the location of noise and vibration sensitive receptors and impact areas from vibration and/or ground-borne noise.

3.1 Summary

As shown in Table 3, Receptors 7, 8 and 9 would result in either ground-borne noise and/or vibration impacts. The combination of both efficient soils and the placement of crossover track increases vibration levels by 20 VdB, resulting in greater impacts.

As noted above, based on the identification of impacted receptor areas, further analysis was done to determine the extent of impacts and the total number of potentially impacted receptors for each significant source of vibration. Based on that analysis, all wood-framed residential houses within 260 feet of the crossover tracks would be impacted by either vibration or ground-borne noise. This impact determination is based upon the additional vibration and ground-borne noise generated from light rail vehicles passing over the crossover tracks and the assumption of efficient soils transmission. Furthermore, for receptors located outside of the 260-foot impact zone from the crossover tracks, all wood-framed houses within 95 feet of the at-grade light rail alignment would be impacted by the light rail system, assuming the use of efficient soils. In total 26 residential properties would be impacted by either ground-borne noise or vibration, as a result of the extension of the alignment.

The assumption of efficient soil transmission is a major contributing factor to impacts at 23 residential properties along South Alston Avenue. For ten of the residential properties impacted, the placement of crossover tracks at the proposed location combined with the assumption of efficient soils are both contributing factors to the impact Figure 3 identifies the locations of potential vibration impacts.

As noted in the D-O LRT Noise and Vibration Technical Report, the FTA guidance requires projects that show impacts due to the use of efficient soils to conduct a detailed geotechnical analysis during final



design. The detailed analysis should also evaluate the effectiveness of appropriate mitigation measures, such as floating slabs, resiliently supported ties, high-resilience fasteners, and ballast mats, which are commonly used on transit systems to reduce vibration levels. This mitigation was included in the Combined FEIS/ROD; therefore, no additional mitigation is anticipated to be required.

4. Comparison of Impacts to Combined FEIS/ROD Tables 4 and 5 identify the noise and vibration impacted sites from the D-O LRT Project summarized in the Combined FEIS/ROD and compares the impact to the anticipated impact for the NCCU Station Refinement. Since no new noise impacts are anticipated for the NCCU Station Refinement, there is no change to the impacts or mitigation documented in the Combined FEIS/ROD. As noted in Table 5, there are additional vibration and ground-borne noise impacts anticipated as a result of the NCCU Station Refinement. However, the existing mitigation to conduct geotechnical surveys to confirm the presence of efficient soils, would still apply.
