center parking lot which would be resurfaced/restriped and include upgraded lighting, landscaping and new sidewalk access. Phase I would also include construction of a new plaza at the northeast portion of the subject site with pedestrian circulation connecting the proposed campus to Stoneridge Mall, BART, and adjacent office and residential developments, although this phase would be designed to facilitate pedestrian connections to internal open spaces (e.g. a central campus courtyard with outdoor collaboration spaces for employees) and buildings developed in future phases of the project. The balance of the subject site would remain vacant under Phase I and be fenced and planted with native grasses. See Figure 3 below for additional detail. Subsequent phases, whose timing is to be determined based on the business needs of 10X Genomics, but is expected to be complete by 2030, would include construction of up to an additional 281,000 square feet of building area within one or two additional buildings generally along the east side of the subject site. Exhibit B shows these buildings in approximate locations, setback between 50 to 100 feet or more from all subject site frontages; however, Exhibit B also shows a 32-foot minimum setback line meaning these future buildings may be shifted anywhere within that minimum setback line as the applicant refines subsequent phases of their master plan. The applicant proposes the maximum height of these later phase buildings would be up to 92 feet (108 feet with rooftop equipment screen) (including rooftop enclosures for mechanical equipment, etc.), although it is likely these future buildings may ultimately be less than 92 feet (e.g. two shorter, but larger footprint buildings compared to what is shown in Exhibit B). The later phases also include construction of an (up to) approximately 60-foot-tall parking structure, providing 1,180 parking spaces, in six levels (five stories, plus rooftop parking) along the west side of the subject site. Recorded agreements between the owners of the adjacent Stoneridge Mall, and this property, require minimum parking ratios of four spaces per 1 ,000 square feet to be provided on the subject property; this ratio would be met by the proposed 1,180 parking spaces. However, the ratio required by the agreements is relatively high compared to the PMC's typical ratios for uses similar to those proposed, and could potentially result in the project being "overparked" based on the project's anticipated employee density and the ultimate mix of land uses at full campus master plan buildout. Since these existing agreements expire in 2028, and it is likely the full campus master plan wouldn't be constructed until after this date, the applicant proposes an overall parking ratio of 3.3 spaces per 1,000 square feet for the entire campus master plan development at buildout. This lower parking ratio may allow for the total number of parking spaces, and size of the parking structure, to be reduced. The proposed project would continue to utilize all existing driveways described above, with the majority of vehicular access focused on Springdale Avenue, which would provide the main ingress and egress from parking areas. Building 1 would have entry and drop-off access from the existing driveway off Stoneridge Mall Road (ring road). Building l's service entry would be screened and integrated into the building design with access from the existing driveway off Springdale Avenue. Buildings 2 and 3 would also have an entry and drop-off point access from the existing driveway off Stoneridge Mall Road at the existing McWilliams Lane signal intersection.
