The proposed gate operation at Entry 1 is a 22 -foot wide security gate that will open from one end and at Entry 2 is a 24 -foot side security gate that will open from one end. Both of the gates will be open during the day and closed at night. There is another rolling gate inside the parking garage that will separate the visitor parking and the residential parking. Therefore, based on the entry design shown on the plans, the operational characteristics of the gate mechanisms, and the setback of each gate from the adjacent public street we have determined that the vehicle stacking area at the gated entries provides adequate storage capacity that will allow vehicles to enter the site without interfering with the traffic flow on the adjacent public street. Parking The proposed project will modify the existing 4 -story 664 space parking garage to provide 531 shared parking spaces (including 51 visitor parking spaces) and 28 private parking spaces for a total of 559 parking spaces. In addition, a curb cutout will be provided along Cabrillo Park Drive for on- street parallel parking. The cutout is approximately 95 feet long and 8 feet wide. Based on the City requirement of 20 feet long parallel space and 5 feet of buffer, a total of 4 vehicles can be accommodated at the cutout (see Figure 8). These parking spaces will also provide short term parking close to the support service retail which may be used by project visitors or by pass -by traffic. The design of the cutout is not expected to impact the thru movement on Cabrillo Park Drive. Furthermore, the cutout ends approximately 260 feet south of Driveway 1 and is not expected to impact the operation of the driveway. REQUIRED MITIGATION MEASURES AND/OR RECOMMENDATIONS Based on the results of the Traffic Analysis there are no required mitigation measures needed to support the project. It should be noted that the proposed first Street Apartments project will continue to provide its fair share for the mitigations identified in the approved First and Cabrillo Towers Project Traffic Impact Study dated March 2007 prepared by EIP Associates. CONCLUSIONS This report presented the findings of a Traffic Analysis carried out for the proposed First Street Apartments project, 254 residential apartment units and 2,424 square feet of support service retail, which is located at the northeast corner of Cabrillo Park Drive and East 1st Street in the City of Santa Ana's Metro East Mixed Use Overlay Zone. The design characteristics of the existing access driveways proposed to serve the site were evaluated based on projected entry and exit peak hour volumes. Based on this evaluation it is concluded that the project access driveways have adequate carrying capacity for the projected demand and pose no significant impact to the adjacent roadway system. It should be noted that the proposed project will be develop 120 fewer residential dwelling units and changing the 8,957 square feet of retail/commercial use into 2,424 square feet of support service retail use. Therefore, the proposed project will reduce 67 AM peak hour trips and 77 PM peak hour trips at the project access locations and to the adjacent roadway network. 12
