1861 west Highway 96 <br /> Arden Hills,MN 55112 <br /> September 23, 2009 <br /> Mayor Stan Harpstead <br /> Ron Moorse, City Administrator <br /> David Grant,Council Member <br /> Brenda Holden, Council Member <br /> Fran Holmes, Council Member <br /> Dave McClung,City Council Member <br /> Dear Mayor,City Administrator, Council Members: <br /> The city is currently discussing the issue of noise abatement due to the separation <br /> aration <br /> g � <br /> of Highway 96/US 10 and the related increase in noise levels. For your consideration,please <br /> review the City Council Agenda packet item 7B of April 14,2008. City staff presented.a <br /> MN/DOT Noise Barrier Study of TH 10 of March 18,2008. In this study abatement criteria <br /> identified that the study area vest of TH 10(East Round Labe homeowners) would be most <br /> benefited by the construction of a noise barrier/sound wall. <br /> The NfNNOISE modeling noise criteria noted"Substantial"is defined as a 5dBA or <br /> greater increase. As detailed in the study the Round Lae area noted levels up to 11.5 dBA in <br /> greater noise levels that can be reduced by a 20' barrier. This study goes on to discuss the area <br /> east of Highway 10 and notes that no substantial reduction in noise >50A would be achieved <br /> by any noise walls or berms in this area. <br /> We feel that the City should first consider steps to financial) support the East Round <br /> � y p �Lake neighborhood. The noise and safety issues on the unorade,of T 10 and related 96/10 grade <br /> separation have been an ongoing issue of concern for our neighborhood. This is demonstrated by � <br /> our letter of petition dated August 7, 1999 (copy enclosed). over 10 years ago we addressed <br /> these issues and the recent noise barrier sound wall study supports our contention. <br /> Please consider this request for financial support to an area of our citythat trul <br /> can y <br /> benefit in noise abatement and increased safety in this neighborhood. <br /> Respectfully yours, <br /> East Round Labe Homeowners <br /> 61 <br /> 42ox-a* <br /> David F.
