Parking As described in Section 2, Modifications to the Original Project, the Modified Project includes a central parking structure that would provide 407 spaces for the onsite residential uses and a surface parking lot that would contain 284 parking spaces, of which 104 would be dedicated to the onsite residential uses and 180 would be shared with the OC Discovery Cube that is located across N. Main Street from the Project site and currently utilizes the site for 180 parking spaces. The shared parking spaces would be used by the OC Discovery Cube from 10:00 a.m. to 5:00 p.m. daily and would be available for the onsite residences between 5:00 p.m. to 10:00 p.m. daily. A rolling gate would separate the onsite residential and OC Discovery Cube parking areas and be opened and closed for management of onsite parking. Overall, the Modified Project would provide 511 spaces for onsite residential and 180 shared spaces. In comparison, the Original Project included 904 parking spaces within a central parking structure to accommodate the demand of the multi-family residences. The Original Project did not include a surface parking lot and did not include shared parking for the OC Discovery Cube. It was planned for the existing OC Discovery Cube onsite parking to relocate. Table T-13 provides the estimated parking demand per the Institute of Transportation Engineers' (ITE) Trip Generation (10th Edition) Land Use 221 - "Multi-family Housing (Mid-Rise)" that provides both average parking needs and 85th percentile parking needs (which provides the highest parking demand 85 percent of the time). As shown, the highest demand from the proposed multi-family residences would be 412 spaces on a weekday. As the Modified Project is proposed to include 511 parking spaces that would be dedicated to the multi-family residences, the Modified Project’s parking would accommodate needs of the development pursuant to the ITE rates, which indicates that impacts related to parking would be less than significant.

The surveys were completed at the Nineteen01 multi-family development located at 1901 East First Street (254 units) that includes 48.4 percent 1 bedroom units, 49.2 percent 2 bedroom units, and 2.4 percent 3 bedroom units; and the Marke multi-family development located at 100 E MacArthur Boulevard (300 units) that includes 51.7 percent 1 bedroom units, 43.6 percent 2 bedroom units and 4.7 percent 3 bedroom units. Thus, the surveyed projects have units that are larger (don’t include studios) and have a greater need for parking than the 68 studios proposed for the Modified Project. The parking surveys were conducted on a weekday (Thursday) and a weekend day (Saturday) for a period of 24 hours. This Parking Analysis is included as Attachment C and Table T-14 provides summary of the parking survey data. 2-181
