whatever the costs are above and beyond the $3250 per decibel per benefiting resident_ This - <br /> option has much more uncertainty to the city than does the lump sum option. <br /> Please be aware that the installation of approximately 2000 feet of the 3000 foot noise wall will <br /> impact existing trees in the area. Some of these trees are mature Oak trees and other areas are <br /> very dense clusters of trees. So, the impacts will be very large. <br /> 3— The City requests that MnDOT commit that fill generated an the project will first stay on the <br /> project and be used for sound mitigation berming in all areas where noise walls are not proposed. <br /> Additional fill material, if it exists, should be used for berming along both sides of 1-694 west of the <br /> project limits. <br /> Mn/DOT response--Mn/DOT has investigated potential berming areas on the project. In looking <br /> at berming areas, it is necessary to look at areas that would allow berming within the existing R/W. <br /> The only area where berming can be constructed within the existing RNV is on the south side of I- <br /> 694 west of old TH 10. Mn/DOT is able to berm in this location while avoiding the area needed for <br /> ponding. The berm will be constructed meeting Mn/DOT design standards for clear zone setbacks, <br /> drainage requirements and wetland impacts. There will be impacts to mature trees with this <br /> berming. Mn/DOT will identify these impacts and requests that these impacts be discussed and <br /> agreed to by Arden Hills. <br /> 4— The City requests that MnDOT prove that the traffic modeling for the 1-6941TH 51 improvement <br /> considered the entire region and the effect the proposed grade separated intersection of TH 10/CR <br /> 96 with the loss of some movements will have on the entire transportation system_ Furthermore, <br /> the City wants MnDOT modeling to document that the proposed improvement wit cause no harm <br /> and actually provide benefit to the county and local road system beyond Hamline Avenue, County <br /> Road F, Lexington Avenue, County Road E and Lexington Bridge over 1-694. <br /> Mn/DOT response—Mn/DOT can confirm that the traffic modeling for this project has considered <br /> the entire region and the effect the'proposed grade separated intersection of TH 10/CR 96 has on <br /> it. In addition, Mn/DOT will prepare an exhibit showing the 2010 traffic counts for the local roadway <br /> system for both the no build and the build condition. This exhibit will show the local traffic <br /> conditions resulting from both projects. <br /> 5 — The City requests that MnDOT commit that there are no city costs associated with the <br /> proposed improvements necessary on interstate, county or local system (including changes that <br /> might be required on County Roads E, F, Hamline Avenue, Lexington Avenue or the junctions <br /> An Equal Opportunity Employer <br />
