SENSITIVE NOISE RECEPTOR REPORT

NOVEMBER 2020

i

On November 5, 2020, an assessment was performed by the project team for sensitive noise receptors (SNRs) along the existing industrial lead track where improvements and construction will occur. Twenty-one (21) homes were observed to be in the closest proximity to the industrial lead track where improvements or new construction will occur. As shown on pages 1-3, SNRs 1 through 13 are scattered on the north and south side along the existing industrial lead track between S 4220 Rd and S 4210 Rd. The approximate distance of these SNRs from the railroad ROW are as follows: 187′, 347′, 386′, 352′, 586′, 340′, 512′, 162′, 425′, 320′, 518′, 447′ and 333′, respectively. These SNRs should experience a temporary increase in daytime noise levels resulting from improvements to the lead track. There are eight (8) SNRs in the area where Track C and Track D will be constructed and track improvements will occur. As shown on pages 3-4, SNRs 14 through 21 are all located on the south side of the existing industrial lead between S 4210 Rd and S 4200 Rd and/or along E 4210 Rd. The approximate distance of the SNRs from the railroad ROW are as follows: 135′, 571′, 135′, 142′, 154′, 130′, 130′ and 444′, respectively. SNRs in this location should experience a temporary increase in daytime noise levels resulting from new track construction and track improvements.

A General Noise and/or Vibration Assessment was conducted to determine the expected impact to the identified SNRs described above. The three sources listed from the source reference list that pertain to the Project are Freight Locomotive, Freight Cars, and Crossover (switches). According to the data that was inputted into the Noise Model Based spreadsheet on pages 14-17, the day-night (Ldn) noise levels are 39, 39, and 6 for each noise source, respectively. All sources have a Ldn (dB) level of 42. According to the FTA guidance manual, Table 81, this dB level is defined as “Occasional Events” that could impact sensitive receptors. (The maximum dB level allowable for Category 2 sensitive receptors is 78.)
