Pearson Place 2' Addition Traffic Noise Assessment EXECUTIVE SUMMARY The Pearson Place 2nd Addition is a proposed residential development in Ramsey, Minnesota consisting of plots for three single family residences. The project is located immediately adjacent to US Highway 10 in Anoka County. The purpose of this study is to determine if the project is in compliance with Minnesota state noise standards, or if needed, to meet provisions in Minnesota State Rules to comply with Minnesota Noise Standards. Predicted traffic noise levels from Highway 10 have been based on traffic volumes from Automatic Traffic Recorder data on the MnDOT traffic data website map and assigned vehicle type percentage. Under Minnesota noise rule definitions, the hour from 6 to 7 AM falls under the nighttime category while the 4-5 PM hour falls under the daytime category. The MinnNoise computer model has been used to estimate nighttime (6-7 AM) and daytime (4-5 PM) sound levels at selected receptors sites on residential plots in the project. Due proximity to Highway 10, the predicted nighttime L10 and LSO levels at all receptor sites are above daytime and nighttime standards for residential land use but can be brought into compliance with state rules if appropriate STC rated windows are installed. Under exceptions to the rules, the STC rating needed for windows and doors with direct exposure to highway noise will depend upon the area percentages of exterior wall components. Individual home design and/or self -standing barriers could provide some shielding from traffic noise.
