ARDEN HILLS CITY COUNCIL - January 28, 2008 7 the City needs some leverage. He questioned staff as to why it is coming back with the "worst case" scenario. Public Works Director Hoag explained staffhas worked with Mn/DOT and determined this was the best starting point to minimize the impacts. He stated a concept is needed to minimize the impacts. He stated they did not know what to add in or take out until they get to the next step. Councilmember Grant stated it was his understanding that three plans would come back to Council; however, one plan with two options for phasing was presented. Pnblic Works Director Hoag explained the reasoning for this. Councilmember Grant questioned that if this was the only plan and it was designed July 23, 2007, why were the other plans presented and why did it take so long. Mr. Roy replied the City asked them to look at it. He stated this was done and different variations of the Diamond Interchange concept were presented. He displayed an aerial view of the design and explained the variations and the two phasing options at the interchange. Mayor Harpstead questioned the future traffic volumes on Highway 10/County Road 96. Mr. Roy replied that traffic analysis, forecasting, and modeling were conducted. He explained the results of these studies. He stated there is a severe safety issue at the intersection of Highway 10 and County Road 96 that needs to be addressed. He pointed out this intersection is ranked number 21 in severity statewide. Mayor Harpstead directed staff to post this information on the website. Mayor Harpstead questioned the need to bridge over for Scherer Brothers and the reason for the frontage road to be located on the west side rather than east. Mr. Roy replied that a bridge over would require grade separation, an elevation over 25 feet higher than Highway 10 and require 800 feet of run out. He stated there is not enough room for a landing on Scherer Brothers to do this. Mayor Harpstead questioned the frontage road south of the intersection to access County Road 96. Pnblic Works Director Hoag replied that if it was possible to work with the wells, moving the frontage road to the east would be considered and evaluated. Councilmember McClung stated there appear to be five wells that would be impacted. Mr. Roy replied there would be an opportunity to minimize the impact to the wells. Councilmember Holden questioned the reason for the stop sign at McDonalds in Moundsview. Mr. Roy explained about half the traffic would go through the traffic signal onto Highway 10. He indicated a safety analysis would be conducted to evaluate the location of the traffic signal. He stated the safety issues at County Road Hand Highway 10 are not as severe as at the County Road 96/Highway 10 intersection.
