CMP Part 4A. Trans ortation Plan � <br /> S UMMAR Y OF EXISTING TRANSPOR TA TION ISS UES <br /> Orono's existing transportation issues generally fall into 3 categories: congestion, <br /> safety and system maintenance. <br /> Congestion is caused by daily and hourly traffic volumes that exceed the traffic <br /> handling capacity of the road system. The capacity for a given roadway is a function of <br /> many factors including the number of lanes,the number and type of access points and <br /> intersections, the configuration of the roadway and the condition of the pavement. <br /> Traffic volumes that exceed the traffic handling capacity can result in traffic backups <br /> that ultimately have a secondary impact on parallel corridors. <br /> The two primary routes in Orono that have historically been congested are County <br /> Road 15 and U.S. Highway 12 (Wayzata Boulevard). County Road 15 currently <br /> exceeds its traffic volume design capacity based on generally recognized standards. A <br /> two-lane arterial facility such as County Road 15 is usually considered as being , <br /> congested when the daily volumes reach 13,000-18,000. County Road 15 has a <br /> 2006/2007 ADT of 18,200 vehicles through the Navarre area and 23,900 vehicles just ' <br /> east of the Orono/Wayzata border, and these counts are forecasted to increase to <br /> 21,000 and 27,000 vehicles per day respectively by 2020. Old Highway 12 had a 2006 <br /> ADT ranging from 17,700 in western Orono to as high as 24,700 (2005 Data) east of <br /> downtown Long Lake. Future traffic counts for the new Highway 12 bypass and <br /> Wayzata Boulevard now that the bypass has been opened are eXpected later in 2009. <br /> Orono has a number of unique Qeographical factors that limit the options for reducing <br /> congestion, the most apparent being Lake Minnetonka and its many bays and <br /> associated wetlands. It is also significant that the volumes of traffic causing <br /> congestion are generated by commuters from developing communities to the west of <br /> Orono. <br /> Safety is an issue of concern where the impacts of congested commuter roadways spill <br /> over into parallel corridors, as well as where major collectars intersect the principal <br /> and `A' minor arterials. As traffic counts have risen and congestion has increased, <br /> access onto County Road 1� has become more difficult and drivers are willing to take <br /> more risks in entering the traffic stream. The addition of a third lane for turns along <br /> County Road 15 east of Orono Orchard Road has improved this segment of 15,but the <br /> roadway west of Orono Orchard Road is difficult to upgrade due to constrictions in the <br /> right-of-way caused by geographic characteristics. County improvements to the <br /> Orono Orchard Road / CR-1� intersection are scheduled for 2009. <br /> Prior to completion of the Highway 12 bypass,its route throu�h Orono and Long Lake <br /> was the primary commuter route for a string of rural communities as far west as <br /> Willmar, and had built-in safety concerns due to the volume of traffic and the many <br /> crossroads. While the level of traffic on Wayzata Boulevard has significantly <br /> decreased. additional future development near the Wayzata Boule�°ard / Old Crystal <br /> City of Orono Communit�� Manabement Plan 2008-2030 Pa�e 4A-9 <br />
