existing traffic levels on Snelling Avenue are much greater than on Fairview Avenue during the peak hours, thus existing traffic levels projected out 12 years to Year 2018 will result in a much greater traffic increase on Snelling than at Fairview Avenue, for example. This, coupled by the fact that a greater percentage (47%) of Northwestern College student trips use Snelling Avenue compared to Fairview Avenue (14%), accounts for the disproportionate impact to the Snelling Avenue/Lydia Avenue intersection. 10. Comment: It is difficult to understand why the Snelling and Lydia and the Snelling and C-2 intersections appear only to be degraded in the worst case, even though those worst cases are quite substantial. Response: Overall infersection level of service is a calculation of average delay for all vehicles moving through an intersection over a peak period. Because future trips due to College expansion pr�dominantly impact the minor street movements (i.e., Lydia Avenue and,;Caui�ty Road G2), there is a disproportionate impact to those pvements. These movements are a/so the most susceptible to impact, beca of the predc�minate allocation of green time to the state highway (i. e., Snelling rr��r�nue). Th�re is very little impaci to either the Snelling/Lydia Avenue or Snellingl�R-C2 pverall intersection levels of service because the allocation of green time fo the predominant northbound and southbound through volumes is virtually unaffected. 11.

Response: Cor►�'� ' ts acknowledged. !t should be noted that LOS D is considered accep��`�` � by most jurisdictions and LOS E conditions for a Year 2018 scenario in a g=' °`ing urbanized corridor is better than some other similar corridors. LOS E operations represent a condition where traffic is af or approaching roadway capacity. 13. Comment: The premise of the study was based on regular students attending classes on the campus at the normal daytime hours. This does not include evening and weekend activities on the campus and during the summer. All of these activities have significant environmental impacts with regard to traffic. Response: Comment acknowledged. The p.m. traffic analysis used traffic volume counts for the 5:00 to 6:00 p.m. peak hour which included nearly as many inbound (students✓staff arriving for evening c/asses) as outbound vehicles. Summer traffic conditions were not analyzed because summer volumes are typically lighter with respect to both College and non-College fraffic and do not represent "worsf case" conditions. Traffic from weekend activities was not analyzed because background traffic peaks vary greatly from weekend to weekend and a/so do not represent "worst case" conditions.
