-ARDEN HILLS CITY COUNCIL — August 31, 2009 10 Mr. Hilden stated that a wall in this area would have been less of a change because of the location of the homes along with the cost reasonableness. Mayor Harpstead asked if the modeling was done with the existing surface or with a bituminous surface. Mr. Hilden stated that it was modeled based on a standard Mn/DOT noise emission baseline so neither surface was taken into account. He will get back to the Council regarding whether this would be comparable to a new or existing road. Councilmember Grant stated that it has been the 'Idea that a bituminous overlay on Highway 10 would reduce the noise. He asked if this would be true and if so homer much the noise level would be reduced. Mr. Hilden stated that a new surface would appear to have less noise than an older one. Mayor Harpstead stated that it had been asked why there had been no sites on the east side of TH 10 and south of County Road 96 used in the study. Mr. Hilden stated that the Noise Area Classification was used and this involves the sensitive receptors within the bounds of the project. The area that has more commercial or retail would not have as many sensitive receptors and the acceptable noise levels in this area would be higher. Mayor Harpstead closed the public hearing at 7:58 p.m. Mayor Harpstead asked for guidance when the resolution would be on the agenda for the Council. Civil Engineer Giga stated that Staff wanted to get feedback from the public hearing and from the Council on how they would like Staff to propose the resolution. It could be brought to the Council at the September 14, 2009 meeting. Mayor Harpstead stated that Staff had been asked to bring forward information regarding the impacts to the Briarknoll neighborhood. Civil Engineer Giga stated that Mr. Chromy was in the neighborhood today and will be providing feedback regarding this.
