This approach would allow portions of the site around the perimeter, which would not be developed in future phases, to have upgraded landscaping in the near term. As noted, in Phase 1 the interior of the site, on portions not used for parking, would be fenced and seeded with native grasses, anticipating development of these areas in the future. The new landscaping tree and plant palette provides a wide range of native, drought tolerant materials consistent with the City's Water Efficiency Landscape Ordinance.

Planning Commission 7 of 12 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.
