ARDEN HILLS PLANNING COMMISSION December 4, 20138 Todd Vanderburgh , 1266 Wayne Ridge Drive, explained that his home abuts the Boston Scientific campus. He expressed concern with the noise levels created at Boston Scientific. He commented that the proposed addition would bring the facility closer to his home. He requested that the noise levels at this site be reviewed. Acting Chair Thompson explained that one of the conditions for approval did address the noise levels on the Boston Scientific campus. There being no additional comment Acting Chair Thompson closed the public hearing at 7:03 p.m. Commissioner Zimmerman understood the noise concerns at this property. It was his understanding that the proposed reconfiguration could minimize the amount of noise coming from the facility. This would greatly benefit the surrounding neighborhood. Judd BraschRSP Architects , , explained he has been working with Boston Scientific for a number of years. He discussed the new equipment that would be added, noting it should be quieter than existing equipment in the building. He explained that Boston Scientific would do its best to contain and control noise within the new addition. He reported measurements were taken earlier that week and the goal would be to reduce or meet the current levels. Commissioner Bartel questioned how the noise levels were tested. Mr. Brasch discussed how the noise levels were captured stating Boston Scientific was currently within the MPCA limits. Commissioner Zimmerman asked if sound-deadening panels would be used. Mr. Brasch indicated a plenum would be used instead to reduce the sound levels. He noted the ducts could be lined to muffle the sound as well. It was his opinion that the noise generated from the site was coming from the roof-mounted units and the equipment located within the proposed addition would not contribute to the noise concerns. Commissioner Stodola inquired if the two new trees could be relocated to provide more screening for the adjacent residents. Mr. Brasch stated there was a bare spot on the landscaping plan, which led to the proposed location. He did not object to moving the trees. Acting Chair Thompson recommended that Mr. Brasch work with the neighbors to find the best location for the two new trees. Commissioner Bartel moved and Commissioner Zimmerman seconded a motion to recommend approval of Planning Case 13-021 for a Planned Unit Development Amendment and Site Plan Review at 4100 Hamline Avenue North based on the findings of fact and the submitted plans, as amended by the five (5) conditions in the December 4, 2013, report to the Planning Commission. The motion carried unanimously (5-0) (Chair Larson abstained).
