Based <br />on our review, we offer the following comments for your consideration: <br />Background Traffic Growth <br />The traffic study identifies a decrease in traffic volumes on study area roadways in recent <br />years. Therefore, no background growth was included for future year 2009 conditions. <br />A cursory review of the Mn/DOT traffic volumes from years 2001 and 2005 indicates that <br />the Average Daily Traffic (ADT) volumes have slightly decreased. However, with the recent <br />expansion and redevelopment of the nearby Rosedale Mall, along with other possible future <br />redevelopments in the surrounding area, it is expected that the background traffic volumes <br />would begin to increase. Therefore, including no background growth does not seem <br />reasonable. Typically, an average annual growth rate of at least one-half percent per year for <br />first ring suburbs in the Twin Cities area is reasonable. <br />Trip Generation and Distribution <br />The traffic study indicates that there will be no increase in trips with the proposed <br />redevelopment of the mall. This does not seem realistic since the main objective in <br />redeveloping a mall is to increase business, resulting in increased traffic levels. Although it <br />is useful to estimate what the mall could generate if fully utilized, it should not be used to <br />represent current conditions. It is misleading to provide a comparison between full <br />utilization of the current mall and a newly redeveloped facility, which would be more <br />attractive and functional. <br />tvww.srfconsulting.com <br />One Carlson Parkway North, Suite 150 � Min�eapolis, MN 55417-4443 � 763.A75.0010 Fax� 763.475.2429 <br />Arr EquaJ Oyyoitur�ity Emptoyer <br />
