Mr. Jonathan Kohn January 27, 2011 Page 5 There is an important common element between the traditional "code" and the Shared Parking calculation methodologies; the peak parking ratios, or "highpoint" for each land use's parking profile, typically equals the "code" parking ratio for that use. The analytical procedures for Shared Parking Analyses are well documented in the Shared Parking, 2"d Edition publication by the Urban Land Institute (ULI). Shared parking calculations for Metroplace utilize hourly parking accumulations developed from field studies of single developments in free-standing settings, where travel by private auto is maximized. These characteristics permit the means for calculating peak parking needs when land use types are combined. Further, the shared parking approach will result, at other than peak parking demand times, in an excess amount of spaces that will service the overall needs of the retail center. Shared Parking Ratios and Profiles The hourly parking demand profiles (expressed in percent of peak demand) utilized in this analysis and applied to the Metroplace are based on profiles developed by the Urban Land Institute (ULI) and published in Shared Parking, 2"d Edition. The ULI publication presents hourly parking demand profiles for seven general land uses: office, retail, restaurant, cinema, residential (Central Business District: CBD and non- CBD), hotel (consisting of separate factors for guest rooms, restaurant/lounge, conference room, and convention area). These factors present a profile of parking demand over time and have been used directly, by land use type, in the analysis of this project. Retail Uses One of the primary project components for the Metroplace is retail space, the ULI retail use profiles are applied directly. In doing so, there is an intermediate step in expressing ULI profiles as a percentage of the week-long peak, thus arriving at a weekday profile and weekend profile each expressed as a percentage of the baseline parking ratio (ULI actually starts with separate ratios for weekday and weekend day, and develops profiles for each accordingly; we've found it more convenient to translate both profiles to a percent of expected maximum demand, which, for retail, turns out to be on a Saturday). The resulting profiles represent the most likely hourly parking demand profile, and are applied to the City's retail parking ratio of 5 spaces per 1,000 SF-GFA. Peak demand for retail uses occurs between 1:00 PM - 2:00 PM on weekdays, and 2:00 PM - 4:00 PM on weekends. 75A-26
