Document Description
The project would implement a large portion of the development envisioned by the East Whisman Precise Plan, which was adopted by the City in 2019. Implementation of the proposed project would allow for the demolition of the existing improvements (i.e., approximately 684,646 square feet of office uses, related surface parking areas, and landscaping) on-site and development of: • Five office building locations totaling 1,317,000 square feet of office uses and resulting in 632,355 square feet of net new office square footage; • Two affordable residential building locations and five residential mixed-use building locations with a total of up to 1,900 residential units (including up to 380 affordable units), up to 30,000 square feet of ground floor retail space, and 20,000 square feet of community/civic uses; • Two stand-alone parking structures and integrated parking at all office and residential buildings for shared district parking within MPMP; •Dedication of land to the City for three new future public parks totaling approximately 7.28-acres and construction of a 2.87-acre privately owned and publicly accessible park developedby the applicant, providing in total, up to 10.15 acres of park open space within the MPMP; •New vehicular circulation, including up to six private streets and a modification to LogueAvenue (a public street), new on-street and off-street bicycle and pedestrian improvements,and new landscaping and trees; and •As an option, the project could include a private district utilities system on-site withunderground utility lines to serve some buildings within the MPMP with water, wastewatertreatment, recycled water, geothermal energy (heating and cooling), and electric power. Theprivate district utilities system, if provided, would a include an approximately 45,000-square-foot Central Utility Plant (CUP), temporary air sourced heat pump, district distribution system,and microgrid system that would include rooftop photovoltaic panels and on-site storagebatteries. In addition to the improvements identified above, the project includes a Vesting Tentative Map to create up to 18 lots, up to 1,900 condominium lots, and up to 140 vertical lots within the MPMP, as well as a Development Agreement to grant implementation of entitlements over a 20-year period. Other aspects of the MPMP include green building and emissions reduction features; construction activities; heritage tree removals and landscaping; site access, circulation, and parking; and a Transportation Demand Management (TDM) plan. The project would result in significant, unavoidable air quality impacts during construction and operations. All other potentially significant impacts described in the draft SEIR would be mitigated to a less than significant level. The project is located within the Middlefield Ellis Whisman (MEW) Superfund Study Area, which is an area designated by the U.S. Environmental Protection Agency as a Superfund site due to the presence of soil and groundwater contamination. Cleanup of MEW Superfund Study Area (including the project site) is on-going, and the site is included on a list compiled pursuant to Government Code Section 65962.5.
