My assessment of the analysis is as follows: <br />1. I concur with URS' assessment that the intersection of CSAH 49 and CSAH 10 operates <br />at unacceptable levels of service under existing and post - development conditions. <br />2. The main cause of poor operating conditions is the inadequate lane geometry at the <br />intersection, particularly for the southbound approach. <br />3. There will be a significant increase in intersection delay with the addition of Spirit Lakes <br />Center trips as average vehicle delay will more than double in the a.m. and p.m. peak <br />hours. <br />4. Nothing short of installing a traffic signal and adding a left-turn lane at the southbound <br />approach will restore operations to acceptable levels of service for existing or post - <br />development conditions. <br />If you have further questions regarding my assessment, please give me a call. <br />An Equal Opportunity Employer <br />
