• The closing of 77th Street will also reduce traffic noise on the 77th Street locations. Traffic Noise - Lake Drive Noise SBP used traffic predictions for 2005 from the TKDA traffic report in order to predict the noise impacts of the additional traffic on Lake Drive. The following table shows the 2005 peak -hour traffic levels at segments of Lake Drive with and without the proposed project, and the resulting increase in noise level. Lake Drive Roadway Without With Development Noise Increase due to Segment Development the Development South of Town Center 1027 1282 1.0 dBA North of Main 997 1086 0.4 dBA 77th to Main 1028 1389 1.3 dBA Any potential noise level increases due to increased traffic along Lake Drive near the project entrance and I -35W will be offset by the introduction of traffic signals causing traffic to slow, and thereby reducing tire noise. Loading Dock Noise The major source of noise from the loading docks will be from the refrigeration units mounted on some of the delivery trucks serving the facility. Super Value, the supplier of the refrigerated foods to the proposed SuperTarget, will be utilizing the Thermo King "Whisper" units. Data from Thermo King indicates these units produce 71 dBA at 25 feet when at high speed. For one truck with a refrigeration unit this equates to 61 dBA at 220 feet, the distance to the nearest home. For two trucks this equates to 52 dBA and for 4 trucks this equates to 58 dBA. Minnesota daytime standards limit noise levels at residences to 65 dBA for 6 minutes in any hour, and 60 dBA for 30 minutes in any hour. An additional 2 -3 dBA could be added to these impacts due to the reflection from the wall. The refrigeration units could, however, exceed night standards. In addition to the refrigeration units, loading dock activity could cause negative impacts on nearby residential property if loading occurs at night. Whether or not it exceeds the MPCA noise standards, noise that could awaken neighbors should be avoided. Hours of loading dock activity must be addressed. Roof -Top Unit Noise Roof -top HVAC equipment will generate noise from the proposed buildings. The equipment must be selected, installed and operated to assure compliance with the Minnesota noise standards. 25. Are any of the following resources on or in proximity to the site: a. Archaeological, historical, or architectural resources? See discussion below. b. Prime or unique farmlands? No c. Designated parks, recreation areas, or trails? Yes d. Scenic views and vistas? No e. Other unique resources? Yes If any items are answered Yes, describe the resource and identify any impacts on the resource due to the project. Describe any measures to be taken to minimize or avoid adverse impacts. a. The proposed project was submitted to the State Historic Preservation Office (SHPO) and was reviewed pursuant to responsibilities assigned them through the Minnesota Historic Sites Act, the Minnesota Field Archaeology Act, and Minnesota rules 4410.1600. A previously- recorded prehistoric archaeological site is located in the project area. The SHPO recommended the site be evaluated in order to determine whether it meets National Register criteria.
