Westwood Professional Services, Inc. prepared a Traffic Analysis for the proposed Elk River Station development to assess potential effects of the Elk River Station development on the local and regional roadway network. The complete Traffic Analysis is contained in Appendix B. Traffic entering and exiting from the development will access Tyler Street. Tyler Street is a four lane, divided roadway with turn lanes at key intersections. The portion of the site east of Tyler Street will be served with two internal roadways. The southernmost of these roadways lines up opposite of the south transit station access and will be a full movement intersection. The northerly access on the east side will be a right in/right out only access point. Further north there is a second access to the transit station to the west of Tyler; this transit access point does not serve Elk River Station movements on the east side of Tyler. Trip Generation The trip generation for the Elk River Station development was determined based on the standard trip generation rates contained in Trip Generaii0n, 6th Edition (institute of Transportation Engineers, 1997). Trip generation data are. provided in the following table. The project is expected to generate a total of 4,593 trips per day and 667 trips in the P.M. peak hour. Table 21.1.

Using this distribution, the various elements of the development were assigned to the roadway network and tabulations were recorded of the new volumes at the Elk River Station access points and the transit access point immediately north on Tyler. The traffic analysis used conservative approach to estimate that the transit station west of Tyler Street and other growth in the Tyler Street corridor will reach approximately 7,000 vehicles per day, with a P.M. peak hour distribution of about 10 percent. These background and development volumes were added together to determine the post development total traffic volumes. ~¥ Westwood Professional Services, Inc. Page 15
