• • Mike Quigley July 21, 2005 providing for a future connection to James Street on the north. Figure 2, "Concept Site Plan," gives a detailed look at the proposed site. For the purposes of this study, one design year was considered, 2005. Two scenarios were considered, an Existing scenario, or operations as they currently exist, and a Build scenario, or operations with the addition of site - generated traffic. In discussions with Anoka County, four intersections were targeted for study and have been included in the study area: > CSAH 23 and County Road 14 (Main Street) > CSAH 23 and the site access (Street A) > CSAH 23 and the Southbound Interstate 35W (I -35W) Ramps > CSAH 23 and the Northbound I -35W Ramps Existing Conditions The existing conditions of the nearby roadway system were documented by a field inventory conducted by RLK on July 20, 2005. In addition, manual turning movement count data was collected from Anoka County and MnDOT documenting existing AM and PM peak hour traffic volumes at the study area intersections. Since only 2003 turning movement data were available, a growth factor was applied to the data to arrive at assumed 2005 Existing traffic volumes. The growth factor was calculated from MnDOT ADT traffic data collected in the area from year 2000 -2004. Based on review of the MnDOT ADT count data, a 3.0% background growth rate was used. Figure 3 provides an overview of the existing (2005) peak hour traffic volumes at the study area intersections. Anoka County/MnDOT are currently planning to improve the I -35 CSAH 23 interchange. Current plans call for year 2007 construction. Capacity improvements to the interchange have not been considered for this analysis in accordance with choosing 2005 as the design year. Anoka County has no current plans to improve the intersection of CSAH 23 / Cty. Road 14, which currently operates as an all -way stop, through the year 2009. Trip Generation / Distribution / Assignment The number trips to be generated by the proposed development was estimated for the weekday AM and PM peak hours, as well as on a daily basis using the data and methodologies contained in the 7th Edition of Trip Generation, published by the Institute of Transportation Engineers (ITE). To ensure a conservative analysis, no pass -by or shared trip reduction was taken. The estimated number of site - generated trips is summarized in Table 1. RLK- Kuusisto, Ltd.
