''1 � .� � Mr. Jeffrey Agnes 4 November 2, 2D07 TRAFFIC FORECASTS Consistent with standard practice, the traffic forecasts and analyses in this report have been prepared for 2009, one year after expected completion of the development plan. Thus, for both the weekday p.m. peak hour and for the Saturday mid-day peak hour, traffic forecasts and analyses have been completed for the following four scenarios: • Existing • Existing with full occupancy of former uses • 2009 no-build • 2009 build We established existing volumes through use of counts conducted by Mn/DOT staff at the Snelling Avenue/County Road B intersection and counts conducted by our staff at the Har Mar access intersections on Snelling Avenue and County Road B. We had to apply an adjustment process to estimate some of the volumes due to abnormal conditions created by the collapse of the I-35W bridge (County Road B was closed at TH 280 following that collapse) and operation of the State Fair during the period of this study. The adjustment process, which was agreed upon by City staff, is summarized as follows: a) Weekday p.m. peak hour volunies. For this purpose, we used the Mn/DOT counts at Snelling Avenue and County Road B, which were recorded in May 2007, together with the entering and exiting traffic at the Har Mar access locations on Snelling Avenue and County Road B. We adjusted the through volumes at the Har Mar access locations on Snelling Avenue and County Road B to be consistent with the volumes recarded by Mn/DOT staff at the Snelling Avenue/County Road B intersection. b) Saturday mid-day peak hour volumes. We conducted full turning movement counts at the Har Mar access locations on County Road B before the I-35W bridge collapse and before the State Fair began operations. Comparing the resultant two-way volume on County Road B just east of Snelling Avenue to the corresponding two-way volume from Mn/DOT's weekday count, we determined that the Saturday peak hour volume was 10°Io lower than the weekday peak hour volume. We then applied that 10°Io reduction factor to all the weekday p.m. peak hour movements at the Snelling Avenue/County Road B intersection to estimate the Saturday mid-day peak hour turn movements. Subsequently, we estimated full Saturday mid-day turn movement volumes at the Har Mar access on Snelling Avenue by accounting for through traffic consistent with the preceding estimated volumes at the Snelling Avenue/County Road B intersection, together with Saturday mid-day peak hour counts that we completed of all entering and exiting trafiic at the Har Mar access location on Snelling Avenue. To assess the impacts of replacing the former uses with the proposed uses, we needed to account for full occupancy of all former uses at the Har Mar Shopping Center. When our existing traffic counts were conducted, the following three uses were closed: • Space 27 - TJ Maxx Store with 24,211 square feet. • Spaces 41 and 42 - multiplex theater, which had a total of 11 screens. • Space 82 - sit-down restaurant with 5,796 square feet.
