I,I.G prepared the <br />parking study for this project in September 2014. <br />SHARED PARKING ANALYSIS <br />Shared Parking Methodology <br />Accumulated experience in parking demand characteristics indicates that a mixing of <br />land uses results in an overall parking need that is less than the sum of the individual <br />peals requirements for each land use. Due to the existing and proposed mixed -use <br />characteristics of PacifiCenter, opportunities to share parking now occur and can be <br />expected to continue with full occupancy. The objective of this shared parking- <br />analysis is to forecast the peal< parking requirements for the project based on the <br />combined demand patterns of different tenancy types at the site. <br />Shared parking calculations recognize that different uses often experience individual <br />peak parking demands at different times of day, or days of the week. When uses <br />share common parking footprints, the total number of spaces needed to support the <br />collective whole is determined by adding parking profiles (by time of day lot- <br />weekdays versus weekend days), rather than individual peak ratios as represented in <br />the City of Santa Ana Zoning Code. In that way, the shared parking approach starts <br />from the City's own code ratios and results in the "design level" parking supply needs <br />of site. <br />It should be noted that the "demand" results of the shared parking calculation are <br />intended to be used directly for comparison to site supply. No further adjustments or <br />contingency additions are needed because such contingencies are already built into <br />the peak parking ratios and time of day profiles used in the calculation. <br />There is an important common element between the traditional "code" and the shared <br />parking calculation methodologies; the peak parking ratios or "highpoint" for each <br />land use's parking profile typically equals the "code" parking ratio for that use. The <br />analytical procedures for shared parking analyses are well documented in the ,Shared <br />Parking 2 "`Edition publication by the Urban Land Institute (ULI). <br />Shared parking calculations for the analysis utilize hourly parking accumulations <br />developed from field studies of single developments in free- standing settings, where <br />travel by private auto is maximized. These characteristics permit the means for <br />calculating peak parking needs when land use types are combined. Further, the <br />31A-24 <br />
