Debra Bloom, P.E. City of Roseville EXISTING CONDITIONS • All comments were addressed satisfactorily. YEAR 2018 CONDITIONS August 7, 2007 Page 2 • Year 2018 conditions analysis was added to the traffic impact documentation to determine the impacts the College expansion would have on the adjacent roadway network independent of the potential Twin Lakes AUAR development. • The background growth rates assumed for this analysis are consistent with average annual growth rates for this area. • This analysis determined that the Snelling Avenue intersections will begin to fail without the College expansion taking place (assuming no mitigation to improve operations). • With the College expansion, all adjacent intersections will degrade further (assuming no mitigation to improve operations). • All mitigation measures identified as part of the analysis are appropriate, except for the traffic signal at the Fairview Avenue/Lydia Avenue intersection. This intersection is reported to operate at an acceptable LOS D or better during the a.m. and p.m. peak hours under year 2018 cumulative conditions. While this intersection has been shown to degrade from existing conditions, the acceptable overall LOS D would indicate that additional mitigation would not be warranted at this time (unless desired by all parties involved and funded independently by the applicant). • The Master Plan documentation appropriately states that the intersections along Snelling Avenue cannot be made to operate at acceptable levels of service with reasonable/feasible mitigation measures. Based on the amount of side-street traffic and volume on the Snelling Avenue anything short of constructing grade-separated intersections at each of the cross- streets will result in a failing level of service. Currently, this high-cost, high-impact improvement is not feasible. • It is recommended that the applicant work with City staff to clearly identify which mitigation measures are the sole responsibilities of the College and which will be monetarily contributed to proportionately based on trip generation estimates. This information shall be added to the Final PUD submittal documentation submitted to City staff. YEAR 2026 CONDITIONS • All comments were addressed satisfactorily.
