Ms. Kellee Preston <br />October 17, 2012 <br />Page 5 <br />Although the Project includes an expansion of square footage, the future attendance levels are <br />not expected to be proportional to the increase in square footage of the site. As the Center gets <br />larger, the number of visitors who will see multiple parts of the building will increase and, <br />therefore, the new parts of the building will "capture" part of their visitation from visitors already <br />coming to the Center. The future parking demand was calculated using the calibrated shared <br />parking model adjusted to account for this internal capture of trips and the proportional increase <br />in patronage. <br />Seasonal Variation. Seasonal variations used in the model are derived from attendance totals <br />obtained from the Center that show April as the peak month. The shared parking analysis <br />summarized in this report projected parking demand over the course of the year (i.e., each <br />month), including late December holiday season. The analysis shows that April peak conditions <br />represent the busiest month of the year for Center. <br />Auto Occupancy. The Project's shared parking analysis used the national averages for auto <br />occupancy, i.e., the typical number of passengers in each vehicle parking at the site, for all land <br />uses. No changes were made to the UL.I average rates. <br />The shared parking model applies these assumptions /inputs and considers each land use <br />separately in order to identify the peak parking demands of each component, as well as for the <br />overall Project. The results of the shared parking model calibration may be found in the <br />Attachment. <br />FUTURE PARKING DEMAND <br />Future parking demand for the Project was determined by applying the observed parking <br />demand rates to the proposed available square footage of parking demand generating uses. <br />The future parking demand is not expected to be proportional to the increase in square footage <br />of the site for a number of reasons. First, and most importantly, the increase in annual visitors <br />to the Center is not expected to be proportional to the size of the expanded Center. The current <br />Center serves approximately 425,000 visitors per year while the expanded Center is expected <br />to serve 612,000 visitors per year after stabilization. Thus, even though the physical size of the <br />Center is doubling, the increase in visitations will increase by approximately 45 %. Secondly, as <br />the Center gets larger, the number of visitors who will see multiple parts of the building will <br />increase and, as mentioned, the new parts of the building will "capture' part of their visitation <br />from visitors already coming to the Center. <br />Further, based on information provided by the Center, the average length of stay at the Center <br />is anticipated to increase from the current level of three to four hours to approximately five to six <br />hours after the expansion. The increased length of stay by visitors is not anticipated to increase <br />the peak parking demand at the site, but the number of hours per day that the parking demand <br />is near its maximum for that day is likely to increase. Based on the seven hour Center opening <br />schedule (i.e., 10:00 AM to 5:00 PM) and the estimated average length of stay, visitors will <br />begin to arrive when the Center opens and leave beginning around 3;00 PM. The future parking <br />demand was, therefore, calculated using the calibrated shared parking model adjusted to <br />account for this internal capture of trips and the proportional increase in patronage. The results <br />are presented in Tables 5 and 6 and in the Attachment. <br />75A -24 <br />
