existing traffic levels on Snelling Avenue are much greater than on Fairview Avenue during the peak hours, fhus existing traffic levels projected out 92 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 Sneiling 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 intersection level of service is a calculation of average delay for aIl vehic/es moving through an intersection over a peak period. Because future trips due fo College expansion predominantly impact the minor street movements (i.e., Lydia Avenue and County Road G2), there is a � :, disproportionate impact to those�movements. These movements are a/so the mosf susceptible to impact, because of the pred6 inafe allocation of green time to the state highway (i.e., Snelling �vertue). ,T�e�,,r�,e s very little impact to either the Snelling/Lydia Avenue or Snell�ng/CR�C2;,�overaU intersection levels of service because the allocation of green fime to the predominanf northbound and ,,;, ,n� southbound through volumes is virtually unaffe,cted. 11. Comment: Several mitigation strategies are sugge`sted to accommodate the College's desire for increased enrollment. Howeve`r� no real solution for problems at�County�Road G2 and Snelling or at Lydia and Snelling are offered. acknowledged. See a/so the response to comment I.B.3. 12. Comment; It appears that even with the mitigation measures proposed, many of �� ,4� which might, not be feasible to implement for a variety of reasons, delays and queues a(ong Snelling at Lydia.and County Road G2 remain at E and D levels. `.K� ��.� Response: Comme �ts acknowledged. !f should be noted that LOS D is considered acceptable by most jurisdictions and LOS E conditions for a Year 2018 scenario in a gro�Ying urbanized corridor is befter than some other similar corridors. LOS E operafions represent a condition where tratfic is at 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 classes) as outbound vehicles. Summer traffic conditions were nof ana/yzed because summer volumes are typically lighter with respect to both College and non-College traffic and do nof represent "worst case" condifions. Tratfic from weekend activities was not ana/yzed because background traffic peaks vary greatly from weekend to weekend and also do not represent "worst case" conditions.
