Associate Planner Wald replied the study is based on the exterior of the building. <br /> <br />Councihnember Cook inquired if they can get close to the standard by using berming and <br />planting and other methods, knowing Highway #10 will change, and can put in something more <br />substantial in the future. <br /> <br />Chris Enger, Land Resource Manager for Ryland Homes, indicated there are indoor and exterior <br />noise standards, and they will be able to meet the interior standards by using FTCo30 glass. The <br />issue then becomes the outside, and it is not the outside for the whole development, it is the <br />outside of thc buildings along Highway #10. Rivenwick Village has decreased the amount of <br />residences along Highway #10 and pulled the residential units back from Highway #10. Beyond <br />that, they have increased the amount of landscaping quite substantially along Highway #10 and <br />are open to other mitigating measures short ora 15 foot high fence. They are looking at the idea <br />of Highway #10 moving in further and the noise being mottled from 200 feet further away. This <br />is not a perfect solution, but they would be willing to do a good compromise compared to a 15 <br />foot wall. <br /> <br />Mayor Pro Tern Zimmerman stated at this point in time he does not know that he would want to <br />deviate fi'om the MPC standards. Possibly when Highway #10 is built the City will receive <br />money for sound walls as was the case with Highway 47. There are a lot of unknowns at this <br />time. <br /> <br />Councilmember Strommen indicated she does feel better that the indoor standards can be met, <br />however, she still feels uncomfortable deviating from the standards. If it is explored how close <br />they can get with the standards it can be determined how much risk the City would be willing to <br />asstlme. <br /> <br />Councilmember Kurak asked how much further the highway will shift to the north. <br /> <br />Assistant Public Works Director Olson replied currently the right-of-way for Highway #10 is <br />approximately 200 feet. It will be a six lane freeway at ultimate build-out and will shift all the <br />way to the lmrth. Regarding funding for the sound wall, he explained the state gave the City <br />sound wall funding for Highway 47, however, that was prior to a comment being included in <br />review letters that states MnDOT will not be responsible for sound mitigation in the future for <br />new development that occurs along a corridor that the City allows. This is what got the City in <br />the sound wall predicament they are in along Highway 47. He asked if the developer will be <br />willing to explore an option with the use of his land for berming. In keeping with the thought <br />that landscaping does not really help sound mitigation, there is a limited amount of opportunity <br />to racet the standards without using land for berming. <br /> <br />Mt'. Enger replied as the builder he has been involved with this project for about eight months. <br />Their first approach was as a mixed use development, and that area was supposed to have a <br />minimum of 70 percent residential. Since then there have been discussions that may have been <br />meant to be a maximum. They have now pulled back as much as they can from Highway 10 to <br /> <br />City Council Work Session/March 30, 2004 <br /> Page 9 of 12 <br /> <br /> <br />
