Spack TRAFFIC S" UDY COMPANY Technical Memorandum To: Jim Waters, Quest Development From: Mike Spack, P.E., P.T.O.E. Date: July 2, 2013 Re: Traffic Review of 4001 Stinson Boulevard Redevelopment in St. Anthony Quest Development is proposing to replace the 58,000 square foot medical office building at 4001 Stinson Boulevard NE in St. Anthony, MN with a 90 unit apartment building. This memorandum documents the potential traffic impact of the renovation. Traffic Generation A trip generation analysis was performed for the proposed site based on the methods and average rates published in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 9`" Edition. The ITE Trip Generation Manual is a compilation of traffic data from existing developments throughout the United States. The results of the analysis are shown in Table 1. These results assume fully occupied land uses. Table 1— Vehicles 720 58,000 sq ft Medical Office Building _1,048 -1,048 -110 29 58 149 (Removed) 90 Dwelling Unit Apartment 300 300 9 37 36 20 Building (Added) Net Change -748 -748 1 -101 8 -22 -129 The Institute of Transportation Engineers' Transportation Impact Analyses for Site Development report recommends a detailed traffic impact study be done for developments generating 100 or more new trips in a peak hour. That is the threshold where development traffic may adversely impact the transportation system and intersection operations should be analyzed. Although the calculations show a significant decrease in traffic, the decrease might not be as large as the amount shown in Table 1 because the medical office building may not be operating at full capacity. It is reasonable to assume however that replacing the medical office building with the apartment building will not result in 4001 Stinson Boulevard generating more than 100 new peak hour trips. Therefore, a traffic impact study analyzing nearby intersection operations is not warranted for the proposed renovation. Conclusions /Recommendations The 4001 Stinson Boulevard redevelopment will have negligible impact on the area transportation system and no improvements are necessary to accommodate the redevelopment plan.
