Debra Bloom,, P.E. <br />City of Roseville <br />July 13, 2011 <br />Page 24 <br />o To improve the side-street delays at the Lexington Avenue North and County Road <br />C2 intersection under year 2030 conditions with the County Road C2 connection, an <br />eastbound right-turn lane should be constructed. With the recommended right-turn <br />lane,, the Lexington Avenue North and County Road C2 intersection will operate at <br />LOS B/F. Side-street delays along County Road C2 will be approximately 90 <br />seconds. <br />o If the side-street delays are considered unacceptable by the City, installation of a <br />traffic signal would mitigate this condition. Based on a preliminary review of the <br />p.m. peak hour traffic volumes, the Lexington Avenue North and County Road C2 <br />intersection will likely meet the peak hour traffic signal warrant under year 2030 <br />conditions with the County Road C2 connection. <br />The current alignment of the truncated section of County Road C2 is straight and in line, <br />and as such presents no significant impacts to adjacent properties due to potential <br />horizontal alignment connections. <br />The combination of the rolling terrain and short vertical curves along County Road C2 in <br />this area cause deficiency in the roadway design such that the current configuration does <br />not meet the design standards for 30 mph in several areas. If the roadway is improved or <br />connected,, it is recommended that the vertical curve lengths be constructed to meet <br />current standards. <br />H:\PrQjects\7477\TS\Report\1 107057477 Draft CR.
