Google’s plans for a futuristic campus in Mountain View’s North Bayshore area could take another step toward reality next week.

The Mountain View City Council will discuss Tuesday whether it will grant Google permits to create its Charleston East campus that will be open to its employees and the public. Google envisions having a canopied 595,000 square foot two-story office building on the 18.6 acre property.

The structure would be unlike any office building in the Silicon Valley, made up of “separate roof panels, held up by a grid of poles,” according to a city report released on Friday. “Vertical glass curtain walls would enclose the structure on all four sides, further allowing the inside to be illuminated by natural light,” the report said.

Google employees would use offices on the first and second stories of the building. Members of the public would be able to walk through a pathway from dawn to dusk on the first floor, with retail and cafes nearby, the city report said. Renderings from Google included in the report show members of the community doing Tai-chi and a green loop for bicyclists and pedestrians. In the southeast part of the Charleston East campus, near Shoreline Boulevard and Charleston Road, Google plans on having a two-acre public plaza for food trucks and events like performances and outdoor markets, the report said.

“Google’s presence in Mountain View is simply so strong that it can’t be a fortress that shuts away nature, that shuts away its neighbors,” said architect Bjarke Ingels, whose firm is a consultant on Google’s campus project, in a video about the space. “It really needs to become a neighborhood in Mountain View.”

But as part of its new campus plans, Google plans to remove 196 heritage trees, which requires city approval. Google says it will plant 392 trees, including oak, willow and buckeye trees, to replace the ones that will be removed. The shift in trees will cause a reduction in tree canopy coverage. Currently, there is about 12 percent tree canopy coverage and that will drop to 3 percent at “the time of planting,” the report said. But 15 years later, the tree canopy coverage is expected to grow to 30 percent, the report said.

The new project will generate roughly $3 million in additional property tax revenue for the shoreline community, the report said. The project will also pay the city $14.9 million in a housing impact fee and $17.9 million that will go to transportation improvements in North Bayshore, the report said. Google will also pay $250,000 to the city related to its North Bayshore Precise Plan and environmental impact report.

Google says Charleston East will have 1,200 parking spaces. On Tuesday, the council will also discuss whether to extend Google’s lease on parking spaces at the Shoreline Amphitheatre to serve as temporary spaces while the project is being developed. Google and Live Nation are seeking to extend a lease on parking spaces at the Shoreline Amphitheatre from Dec. 13, 2017 to the end of 2020. If the city council approves this, Google says it will pay the City of Mountain View a one-time sum of $600,000 and annual rent of $2.25 million for renting the two parking lots. If Google is granted occupancy on its new Charleston East campus before the end of 2020, the $600,000 payment would go toward the rent on the parking lots. In addition, Google says it will restrict parking for Charleston East on its property at 2171 Landings Drive and other Google property near Charleston East campus.
