In general, there are two methods that can be used to estimate the site's peak parking demands. These methods include: 1. application of City code requirements (which typically treat each use in the mixed-use center as a "stand alone" use at maximum demand); and 2. application of shared parking usage patterns by time-of-day (which recognizes that the parking demand for each land use component varies by time of day, day of week, and/or month of year). The shared parking methodology is certainly applicable to Santa Ana Downtown Plaza, as the individual land uses (i.e., retail, restaurant, and office uses) experience peak parking demands at different times of the day. PARKING CODE REQUIREMENTS To determine the number of parking spaces required to support the parking needs of the existing and proposed uses at Santa Ana Downtown Plaza, parking demand was first calculated using the City of Santa Ana Zoning Code. As mentioned previously, City parking code requirements typically treat each individual use in the commercial center as a "stand alone" use at maximum demand, as opposed to an integrated part of the commercial center. The City of Santa Ana specifies a parking ratio of 5 spaces per 1,000 SF of retail/commercial uses, 6 spaces per 1,000 SF for medical office uses, and 10 spaces per 1,000 SF for restaurant uses. Table 2 summarizes the parking requirements for the existing and proposed uses at Santa Ana Downtown Plaza using the above parking code ratios. As shown, direct application of City parking ratios to the proposed development plan results in a total parking requirement of 596 parking spaces. With a proposed on-site parking supply of 505 parking spaces, a theoretical parking deficiency of 91 spaces is forecast. However, as previously mentioned, there is an opportunity to share parking spaces based on the utilization profile of each land use component. The following section calculates the parking requirements of the proposed project based on the shared parking methodology approach. :\ '2<(JO",2(Jol259LRO]!<'JI,.2S9I Update,l ramsa Expan"on Shared Parking Ana1Y55A~44
