Dennis Welsch - 2- January 6,2005 The year 2020 forecast volume on County Road D between �airview and Cleveland Avenue would increase fiom 14,600 (with Twin Lalces Parl�vay) to 17,500 under the proposed option. This would represent a 20 percent increase in traffic. From a traffic operations perspective the 2001 AUAR noted that the five-legged intersection of Fairview Avenue and County Road D currently operates at capacity, and that improvements are needed regardless of any additional development in the Twin Lalces area. With improvements the intersection could operate at level of service `D', which is acceptable in the pealc hour. However, the additional traffic fiom eliminating Twin Lalces Parl�vay would degrade that service level, but not below a level of service `D'. (Level of service 'D' indicates that most vehicles would have to wait at a traffic signal, but not more than one signal cycle.) The second impact would be to increase traffic on County Road C in general, and two movements in particular: • left turns from eastbound County Road C to northbound Fairview Avenue • left turns from southbound Cleveland Avenue to eastbound County Road C "I'he year 2020 forecast volume on County Road C between Fairview and Cleveland Avenue would increase to over 30,000 vehicles in some segments, which approaches the capacity of the four-lane divided roadway design currently under construction. Traffic analysis conducted as part of the AUAR (and subsequently updated for alternative land use concepts) indicates that the above intersections could be made to function at Level of Service 'D' with proper intersection improvements. However, the intersection of Fairview Avenue and County Road C would require two left turn lanes to operate at Level of Service E with the disconnected Twin Lalces Parl�vay. Similarly, the capacity of the intersection of County Road C and Cleveland Avenue, as well as the segment of Cleveland Avenue between Twin Lalces Parlcway and County Road C would approach failing conditions with additional traffic using that intersection. The distance between Twin Lalces Parl�vay and County Road C is approximately 600 feet at that point. The increase in traffic weaving to or from the I-35W ramp and County Road C would have a significant negative effect on the roadway capacity. Furthermore, the number of southbound left turns would increase to 750 vehicles, requiring additional left turn capacity above that which is planned. Finally, the proposed elimination the Twin Lalces Parl�vay segment would increase traffic desiring to use the Arthur Street intersection with County Road C. Ramsey County is currently designing a full-access unsignalized intersection at this location. Existing and planned land uses in the Arthur StreebTwin Lalces Parl�vay portion of the Twin Lalces area are expected to generate approximately 5,400 trips per day. The proposed closure of the parlcway would force nearly all of these trips to use either Fairview Avenue or County Road C (via Arthur Street).
