ARDEN HILLS CITY COUNCII,WORK SESSION-AUGUST 10, 2009 3 Mayor Harpstead explained that one drawback from the berming would be the removal of existing trees which would create an immediate loss of sound mitigation that would need to regrow. Mr. Chromy indicated that the trees in this area were not large enough to create any sound barrier at this time, but that they could be replanted with conifers in such a way to provide future screening and perceived sound mitigation. Councilmember Holden expressed concern for helping one neighborhood affected by the noise and that this may lead to other neighborhoods voicing their concerns. Mr. Chromy stated that in order for MnDOT to consider noise mitigation the mitigation would have to be reduced by five or more decibels at the affected properties. Councilmember McClung indicated the topography in this area allowed some homes to be protected from the noise. Councilmember Holden questioned if there was any special legislation or funding sources available to the City to assist in funding the berm. Councilmember McClung remembered that the City's state representative would be willing to work at a State level for noise mitigation. Civil Engineer Giga indicated something was introduced at the State level but did not pass the initial stages. Councilmember Holmes questioned the expense for the berm. Mr. Chromy stated the estimated expense was between $25,000-50,000 if done in conjunction with the County's project. He stated there would be considerable cost savings because the material was already paid for and near the site. Mayor Harpstead suggested the fill be used from CR96, if available, to reduce the expense to the City. He felt the estimated $25,000-30,000 was a rational amount of money to spend for the potential noise reduction benefits. Councilmember Holden agreed stating the berm would greatly benefit this neighborhood given the cost savings.
