Planning Commission Minutes Page 6 August 23, 2005 --------------------------- Mr. Koppy stated that the building was oriented to take advantage of the southern exposure in order to prevent icing up of the tank and towers in the winter. He stated that they would look at adding additional height to the berm in order to provide a better screening. Mr. Koppy noted that given the distance of the building from the residences, the storage tank and cooling towers will virtually blend in with the building, as will the loading dock doors. Mr. Koppy stated that the storage tank will contain the backup water supply for the cooling system, which is run on water. He stated that the only exhaust will be steam. Commissioner Stevens stated that he liked the overall design of the plan. He stated he has some concern that the building does not meet the design standards regarding breaks in the building facade. He felt that the applicant should try to screen the tank and towers as much as possible to the residential neighborhood south on County Road 30 (Mississippi Road). Commissioner Westgaard asked it would be possible to design the 45-foot storage tank horizontally. Mr. Koppy stated that they looked at this option, and the possibility of two tanks versus one, or to reduce the capacity, but they found that this size is the minimum acceptable size (45 feet high by 45 feet in diameter). He noted that the tank only provides a 4-hour emergency supply. Commissioner Westgaard suggested designing a 31-foot high, 75-foot diameter tank. Mr. Koppy stated that they could study this issue further. Commissioner Offerman stated that he he would have liked to seen the tanks included in the elevation drawings. Mr. Koppy stated these will be provided for the City Council meeting. Mr. Manthey explained that water drips down the sides of the cooling towers and fans blow on the water which provides cool air to maintain proper temperature for the equipment, similar to how a radiator functions. Mr. Manthey also explained that principle of stratifying the water tanks (tall and narrow) to keep it cool, and that spreading the water horizontally (using a wider, shorter tank) would be ineffective. He stated that he understands that people live nearby and that they will further evaluate the berm and plantings. Mr. Manthey stated he did not think it was necessary to require the exposed aggregate, since that the building s would be set back nearly 300 feet and it would not be possible to see that type of detail from that distance. Commissioner Lemke asked if the towers and tanks would be the same color as the building. Mr. Manthey stated yes, they would be same color and would be camouflaged against the building. Mr. Koppy explained that he would like to address the requirement for the 4-foot off-sets per 160 feet of building length. He stated that they would not be able to maintain security if this requirement were imposed, as it would create blind spots for security cameras. He stated that they are willing to work with staff on this issue. There being no further public comments, Chair Anderson closed the public hearing.
