Memorandum to Dennis Trooien, Dennis Properties Subject: Traffic and Parking Study for Proposed Redevelopment of Arden Plaza Page 13 of 15 September 17,2007 shows a total of 408 parking spaces. Thus, the current site plan will provide adequate parking supply to meet the projected demand upon completion of the proposed redevelopment. . Relatively high parking demand near south end of site. We understand from comments raised at the Planning Commission meeting on August] that parking demand near the south end of the site is greater than elsewhere on the site. To determine whether the current site plan would provide adequate parking supply in this area, we reviewed the proposed supply and projected demand south of the driveway on Lexington A venue. As per the current site plan presented in Figure], the total parking supply in that area is 86 spaces. For uses in the existing retail building that are south of the driveway on Lexington A venue and assuming] 00 percent retail for the proposed building C, the total parking demand in this area is ]47 spaces. Thus, for the area south of the driveway on Lexington A venue, the parking demand would be 6] spaces greater than the proposed supply. This shortage in parking supply is addressed as follows: o The developer presently is revising the site plan to accommodate the] 4,300 square feet for building C in a two-story building. This is different from the plan shown in Figure], which shows a one-story building. This change will reduce the footprint for this building and, thereby, provide more space for parking. Specifically, this change will increase the parking supply in the south area by about 37 spaces, to ] 23 spaces. o As indicated earlier, we assumed 100 percent retail for building C to be conservative in our traffic and parking projections. Based on recent discussions with the Developer, we understand that only 50 percent of building C will be retail and the remaining 50 percent will be office space. The peak demand for retail uses typically occurs in the evenings and on weekends when the parking demand for office is virtually zero. With 50 percent office, the peak demand for the area south of the driveway on Lexington A venue will only be 126 spaces. With greater parking supply due to reduced footprint for building C, the total number of spaces in the area south of the driveway on Lexington A venue will be ] 23. With 50 percent of building C being retail, the total demand in that area will be ] 26 spaces. Thus, it is expected that the current site plan with the changes to building C will provide adequate parking supply near the south end of the site upon completion of the proposed development. . Head-in parking along east edge of existing retail building. As shown in Figure], the current site plan includes head-in parking along the east edge of the existing retail building. Based on our review, we believe that the head-in parking will provide satisfactory operations within the site for the following reasons: o Reduces number of pedestrians that have to cross the drive aisle in front of the building. o Safer for handicap motorists as they do not have to cross the drive aisle.
