ARDEN HILLS CITY COUNCIL – APRIL 26, 2021 15 <br /> <br /> <br />Councilmember Holden requested further clarification on which pieces of equipment would be <br />replaced. <br /> <br />Mr. Hejl stated the equipment on Building 14 that was included in the noise study included <br />compressor units and vacuum pumps that have been mitigated since the 2006 study. He indicated <br />there was also a chiller unit on top of the roof that supports the HVAC system, along with air cold <br />units that service the controlled environment in the manufacturing area of the building. He <br />explained the chiller unit on the far north end of the building was past end of life and causes the <br />most noise from the study. He reported this one unit would be removed and replaced. <br /> <br />Councilmember Holmes commented this has always been a confusing issue for her. She <br />indicated only the chiller would be removed but it would be replaced with a new chiller. <br /> <br />Mr. Hejl stated that was correct. <br /> <br />Councilmember Holmes questioned when this would happen. <br /> <br />Mr. Hejl explained this would happen during the duration of the expansion project. He stated the <br />project was expected to be done by December of 2022. <br /> <br />Councilmember Holden asked if both chillers would be operating at any one time. <br /> <br />Mr. Hejl stated this would not occur. <br /> <br />Further discussion ensued regarding the future mechanical needs for Boston Scientific. <br /> <br />Councilmember Holden requested further information regarding the tree replacement plan. She <br />understood the applicant was interested in planting more trees and reported the area down by the <br />adjacent homes does not have a large number of trees currently. She questioned where the <br />additional trees would be placed. <br /> <br />John Larson, RSP Architects, reviewed the tree replacement plan in further detail with the <br />Council. He noted only a portion of the trees that would be planted on the westerly side of the <br />building were shown on the plan. He explained he had submitted an updated landscaping plan <br />(Sheet L161) to staff, but this drawing was not included in the packet. He indicated more trees <br />would be planted to the north along the western edge of the building. <br /> <br />Councilmember Holden requested staff changing the drawing on the screen to show where the <br />clusters of trees would be located. <br /> <br />Councilmember Scott stated for a point of order, the City Council had reached its three hour <br />time limit for this meeting. <br /> <br />Mayor Grant explained the Council had to make a motion to extend the meeting. <br /> <br />MOTION: Mayor Grant moved and Councilmember Holden seconded a motion to <br />extend the meeting to 11:00 p.m. A roll call vote was taken. The motion <br />carried (4-0).
