Jeremy Larson June 26, 2019 Hampton Companies, LLCPage 3 No person may violate the standards established in part 7030.0040, unless exempted by Minnesota Statutes, section 116.07, subdivision 2a. Any municipality having authority to regulate land use shall take all reasonable measures within its jurisdiction to prevent the establishment of land use activities listed in noise area classification (NAC) 1, 2, or 3 in any location where the standards established in part 7030.0040 will be violated immediately upon establishment of the land use. Analysis Methodology Noise Monitoring Field measurements of existing noise levels were collected at the proposed assisted living/extended care facility site on May 30, 2019. Noise levels were monitored for one hour during the nighttime period (6:00 a.m. to 7:00 a.m.) and one hour during the daytime period (7:00 a.m. to 8:00 a.m.). A trained noise monitoring technician was present for the entire field measurement session to ensure correct operation of the sound level meter (SLM). The field measurement datasheet is attached. Noise Modeling The proposed assisted living/extended care facility is on the south side of Highway 10, east of Ramsey Boulevard. Existing land uses adjacent to the site include commercial and residential uses. The dominant source of noise at the site is from vehicles traveling on Highway 10. Therefore, modeling was completed to identify traffic noise levels at the proposed assisting living/extended care facility site and to evaluate noise abatement measures. Noise modeling was done using the noise prediction program of the FHWDOT for use in Minnesota. This model uses traffic volumes, speed, class of vehicle, and the typical characteristics of the roadway being analyzed (e.g., roadway horizontal and vertical alignment). The noise modeling assumed free flow conditions through the Highway 10/Ramsey Boulevard intersection. Traffic data for noise model input files included year 2021 estimated traffic volumes for Highway 10. Existing (2018) traffic volumes for Highway 10 were obtained from Minnesota Department of Transportation (MnDOT) Metro District intersection traffic counts for Highway 10 and Ramsey 1 Boulevard. Year 2021 traffic volumes were estimated based on a historical growth rate on Highway 10 of one percent. Year 2021 was identified as the year for analysis because this is the assumed year that construction of the proposed assisted living/extended care facility would be complete.
