Pearson Place 2nd Addition Traffic Noise Assessment 3.0 SUMMARY OF FINDINGS Predicted traffic noise levels from Highway 10 on the proposed Pearson Place 2°d Addition residential development in Ramsey, Minnesota have been based on traffic volumes from MnDOT traffic flow website data. The MinnNoise traffic computer model has been used to estimate nighttime (AM) and daytime (PM) sound levels at assumed receptor sites at the perimeter of proposed building footprints on the property. A total of seven noise receptor sites have been evaluated and compared with the Minnesota noise standards for residential land uses. While the predicted levels were in excess levels contained in the standards, exceptions to the rules permit the commercial noise standards if a 30 dBA reduction exterior - to -interior sound level reduction can be achieved with appropriate exterior facade design. An exterior facade with a minimum of a 2x6 wall with siding, acoustical insulation and a 5/8-inch gypsum interior layer and glazing with an appropriate STC rating can meet the exemptions to the rule. The addition of a noise wall or barrier would not be needed for noise control purposes. However, if outdoor uses are to be provided on the site such as patios or entertainment areas, these could be incorporated into the building design to provide shielding of traffic noise or provided with individually designed noise barrier shielded areas. y:Ajobs\2024jobs\224002\report\pearsonpl2ndadd-traffic-noise-assessment.doc David Braslau Associates, Inc.
