improvements to accommodate the proposed development. The study evaluated all three phases of the development to help illustrate the timeframe in which improvements may be necessary. To evaluate the existing traffic operations, SRF gathered data for the intersections at I-694 and Lexington Avenue; Red Fox Road and Lexington Avenue; Target Service Road and Lexington Avenue; and Grey Fox Road and Lexington Avenue. Based on an analysis of current conditions, it was determined that all intersections are operating at an acceptable Level of Service (LOS) C or better during the a.m. and p.m. peak hours. Two access scenarios were reviewed for the Lexington Station development. Scenario A utilizes the existing shared access located along Lexington Avenue approximately 350 feet south of Red Fox Road. Scenario B includes the construction of a west approach at the Lexington Avenue. The applicant has proposed maintaining Scenario A during Phase I and Phase II, and implementing Scenario B for Phase III. The results of the Phase I build operations analysis indicate that all study intersections are expected to operate at an overall acceptable LOS C or better. The study does indicate that the northbound queues at the Lexington Avenue/Red Fox Road intersection are expected to extend beyond the existing shared access under Scenario A during the p.m. peak hour. However, this is considered more of a safety issue rather than an operational issue. The City and Ramsey County will monitor this access driveway and consider modification, if necessary. The results of the Phase II build operations analysis also indicate that all study intersections are expected to operate at an acceptable overall LOS C or better. The queuing issue along Lexington Avenue identified for Phase I is expected to continue, but is not expected to increase significantly with the build-out of Phase II. For Phase III, the analysis was completed under Scenario B access conditions. The results of the build operations analysis show that all study intersections are expected to operate at an acceptable overall LOS D or better, indicating an increase in intersection delay from the previous phases. The study reports that LOS D is still generally considered acceptable by drivers in the Twin Cities metropolitan area. Eastbound queues at the Lexington Avenue/Red Fox Road intersection are expected to block the east access along Red Fox Road approximately 20 percent of the p.m. peak hour. The study concludes that construction of a right-turn lane at the Lexington Avenue/Red Fox Road intersection is warranted to alleviate this issue. Based on the Phase III traffic forecasts, SRF determined there would not be sufficient volume to meet the traffic signal warrant criteria at the Lexington Avenue/Target Service Road intersection. However, the study states that if a signal were to be installed, there would likely be sufficient diversion to warrant the signal and provide relief to the Lexington Avenue/Red Fox Road intersection.
