MINUTES <br />CITY COUNCIL <br />NOVEMBER 2G, 2003 <br />traded for gaps in noise walls proposed along County Road D and along <br />the Twin Lake area. <br />Pete Wasko reported that each individual piece of noise wall must stand <br />on its own merits. There is no pot of money set aside for noise walls that <br />allows the substitution of one wall for another. <br />The City Administrator asked how far back the acoustic benefit of a noise <br />wall is measured. Wasko replied that the effectiveness is measured for a <br />distance of 500 feet back from where the wall is placed. <br />Pafko indicated that there is the potential to add the section of noise wall <br />along County Road D east of Edgerton Street. It was noted that a new <br />apartment building is being constructed in this location; therefore, the <br />added residential population should result in the necessary criteria being <br />met for this section of wall. <br />Jeff Gibbens pointed out that the two gaps in noise walls along County <br />Road D east of Edgerton currently contain double-faced billboard signs. <br />The location of billboards or commercial businesses is factors that <br />complicate the decision as to whether the noise wall goes in or not. <br />Paflco noted that MN DOT is financially responsible for any negative <br />business impact that would result from the installation of a noise wall. If a <br />noise wall cuts off visibility to a billboard or business, this is considered a <br />negative financial impact. <br />The City Administrator suggested that a noise wall could be jogged <br />around a business. Pafko also indicated that the City of Vadnais .Heights <br />could allow these billboards to be raised so that the noise wall would not <br />impact visibility. However, MN DOT would have to pay for the raising of <br />the noise wall. <br />Gibbens also indicated that if a noise wall is determined to be acoustically <br />effective, but not cost effective, There is the opportunity to get the wall <br />installed if the City shares in the cost. Wasko indicated that the cost of a <br />noise wall is approximately $300 per linear foot fora 20-foot high wall, or <br />$15 per square foot. <br />Pafko noted that with regard to the gap along the Twin Lake area, that <br />adjacent property is undeveloped and there is no approved plat for this <br />property. Therefore, a noise wall does not meet the necessary criteria. <br />Pafko indicated that if the property is developed after the Unweave the <br />Weave project, the property would not qualify for the State's retrofit <br />
