Due to the unique characteristics of the project's mixed-use development, opportunities for shared parking can be expected. The objective of this shared parking analysis is to forecast the peak parking requirements for the project based on the combined demand patterns of different land uses at the site. Experience indicates that combining different land uses whose parking demands peak at different times (of the day or week) generally result in a parking demand that is significantly lower than the summation of individual peak demand factors or City parking code requirement for each use. According to the ULl's Shared Parking publication, shared parking is defined as parking space that can be used to serve two or more individual land uses without conflict or encroachment. Given that restaurant/food uses have peak periods (afternoons and evenings) that differ from retail uses (early afternoons), it is appropriate to utilize the shared parking concept to forecast the overall parking demand for the site. The ULl Shared Parking publication provides hourly parking accumulation rates for retail, restaurant, and office uses, expressed as a percentage of the peak demand for the day. For retail uses, peak demand occurs between 12:00-2:00 PM on weekdays and between 2:00-4:00 PM on Saturdays. The hourly factors shown for retail uses are taken directly from ULI. The retail demand profile was applied to retail uses, as well as the Famsa furniture and appliance retail store. According to the ULJ Shared Parking publication, restaurant uses are shown to experience peak demands between 7:00-10:00 PM for both weekday and Saturday. The restaurant demand profile was applied to all of the restaurant land uses (i.e., fast- food and dine-in restaurants). For office uses, peak demand occurs between 10:00 AM-12:00 PM on weekdays and is minimal on Saturdays. However, given that some business offices may potentially be fully operational on the weekends, the weekday general office parking utilization profile was applied to the weekend business office use. The office parking demand profile was applied to medical office uses. N \2<()()\204259I\R,'p<,n.2S9Il'pdaled ram," Expansion Shared Parking Ana'YS!)75-X~45
