Ryan Streff October 4, 2013 City of Arden Hills Page 14 The ITE parking generation demand rates use key inputs, such as facility size and travel behavior characteristics based on utilization surveys of particular land uses, to estimate parking demand. The ITE Parking Generation Manual, 4th Edition estimates an 85th percentile demand based on the study survey locations. The 85th percentile is a statistical measure that represents the point at which 85 percent of the study sites had an observed peak period parking demand equal to or less than the value. Furthermore, it is good practice for the parking supply of any facility to equal the peak parking demand plus an additional 15 percent. This extra supply reduces the unnecessary circulation of vehicles looking for parking and the perception of inadequate parking. Based on the review of the existing parking supply/demand and the ITE calculations for future conditions, the current 777 parking spaces are more than adequate to meet the future demand of the facility. As Bethel University occupies more of the facility over time, the peak parking demand is expected to decrease. This is primarily due to the reduction in office space, which typically requires more parking than a university. Shuttle Service A shuttle service is proposed between the main Bethel University Based on correspondence with Bethel staff, the shuttle service w the campuses with no more than four buses in circulation during any period. Based on this assumption, each bus is expected to make two complete round trips during each hour, which includes dwell time for loading/unloading of passengers. Specific loading zones and routes of the shuttle service have not been determined at the time of this study. However, a cursory review of the area indicates there is only one logical route from the proposed expansion to the main campus. This route, traveling from the proposed expansion, would utilize Pine Tree Drive, County Road E, and Old Snelling. However, there are two potential routes from the main campus to the proposed expansion that could be utilized. The first route would follow the same path previously mentioned, second route would exit the main campus via Snelling Avenue and utilize the County Road E West Ramp. Although this second route would likely be slightly faster from a travel time perspective, it is not ideal to have a ÑlocalÒ type of trip on a more ÑregionalÒ type of facility such as Snelling Avenue, particularly for only approximately one-quarter mile. Furthermore, direct access to Snelling Avenue from the main campus may create a potential safety issue due to the speed differential of the buses and vehicles along Snelling Avenue. Therefore, given that the tr it is recommended that the proposed shuttle service utilize the first route identified along Old Snelling. As previously mentioned, specific shuttle service loading/unloading zones have not been identified. When planning these locations, the location/size of the loading/unloading zones and pedestrian waiting areas should be designed to ensure there is sufficient space for users to safely wait, while limiting any sight distance impacts or conflicts with driveway aisles. This includes zones at both the main campus and the proposed expansion.
