1 STS Swing Traffic Solutions within Elk River or destined to locations such as the Target Center or the City of St Cloud, it is evident that taking the frontage road to 1461" Street and TH 10 then driving to a destination is 2 to 3 minutes faster than driving on Yankton Street SW to Waco Street SW then to either TH 10 or Mississippi NW. To provide a very conservative estimate of traffic distribution it is assumed that half of the local trips (those staying within Elk River) would choose to drive to their destination without traveling on TH 10. In other words, 15 percent (higher than likely to occur) of the site generated traffic would travel through the West Oaks neighborhood, and 85 percent would utilize the frontage road to reach TH 10 via 1461n Street. Traffic to/from the proposed development during the Peak times will be distributed to the site as follows: • Entering the site —10 trips will enter via the frontage access access, and 2 trips will enter via Yankton Street SW access during the AM Traffic Peak; and 29 trips will enter the site via the frontage road access, and 5 trips will enter the site via the Yankton Street SW access in the PM Traffic Peak. • Exiting the site — 28 trips will exit via the frontage road access, and 5 trips will exit via Yankton Street SW during the AM Traffic Peak time; and 20 trips will exit via the frontage road access, and 3 trips will exit via Yankton Street SW during the PM Traffic Peak time. To put this in perspective the existing neighborhood West Oaks Development, including the Assisted Living site, generates 76 trips during the AM peak hour and 104 trips during the PM peak hour. This translates to approximately one trip every 47 seconds during the AM peak hour and one trip every 35 seconds during the PM peak hour. The proposed development conservatively will add 7 trips (less than ten percent of the existing neighborhood traffic) during the AM peak hour or one trip every 8.5 minutes; and 8 trips (less than eight percent of the existing neighborhood) during the PM peak hour or one trip every 7.5 minutes. This level of increase will not be noticed or affect the livability of the neighborhood. Further, the development of Broadway on 10 Residential and the connection to the frontage road will likely result in at least 30 percent of the West Oaks traffic diverting to the frontage road as it will take less time to reach their destinations, reducing the total traffic that will travel through the neighborhood. It is noted, per Minnesota State Aid Standards two lane roads have the capacity to carry 10,000 vehicles a day or 1,000 trips during the peak hour, before improvements such as designated left and right turn lanes at intersections are needed to improve the operations. Similarly, neighborhood collector streets often carry 400-500 trips during the peak traffic times without adversely impacting driver delays. The existing conditions are not close to these numbers, and the addition of Broadway on 10 traffic will not impact driver delay or roadway operations. In conclusion, the development peak demand occurring during the AM and PM Peak traffic hours will not adversely impact the West Oaks neighborhood or other current traffic conditions in the vicinity of the site. The site will function well as proposed. Please contact Vernon Swing at s,,.igtraffic@gmail.com or 612-968-4142 with any questions. 2 1 P a g e Broadway on 10 Residential, Elk River
