Debra Bloom, P.1;. <br />City of Roseville <br />January 15, 2008 <br />Page 23 <br />® under year 2030 build conditions, two additional intersections will operate unacceptably <br />during the p.m. peak hour with the Twin Lakes AUAR Update scenario C recommended <br />improvements and the additional p.m. peak hour trips. Tl-e queues associated with the <br />County Road C/Cleveland Avenue intersection negatively impact the Cleveland Avenue/I~ <br />35W NB Ramps intersection. The failure of two additional intersections under year 2030 <br />build conditions indicates that additional improvements are necessary to obtain acceptable <br />levels of service. <br />o In order to improve the poor operations at these two intersections, the following <br />roadway improvements are recommended {consistent with t1--e Tern Lakes AUAR <br />Update}: <br />Cleveland Avenue at Corrnt Road C <br />• Construct an additional southbound left-turn lane {dual left-turn lanes) <br />Construct a southbound right-turn lane <br />• Based on our analysis results, the additional traffic from the proposed McGough <br />development can be accommodated under year 2011 conditions with relatively minor <br />improvements to the adjacent roadway network. However, as additional developments in the <br />Twin Lakes AUAR area begin to develop, more intense improvements will be needed to <br />accommodate all of the traflac combined (year 201 and year 2030). <br />H:1Projects163234TSlReport46323 Draft McGough Twin Lakes T5~011108.doc <br />
