SAN JOSE — Google is expected to begin work this year to prepare the huge site where the tech titan is planning a game-changing new transit-oriented neighborhood on the western edges of downtown San Jose.

The mixed-use village is expected to include office buildings, homes, restaurants, shops, hotel rooms, open spaces, cultural centers and entertainment hubs and would sprout near the Diridon train station and SAP Center.

“We’re now working on concept plans for the site preparation and infrastructure improvements needed to support the future development of the project,” Sheela Jivan, Google’s director of real estate development, San Jose, said in comments emailed to this news organization.

Plenty of work must be started and completed to prepare the locations and install or upgrade infrastructure before construction can even begin on the actual office buildings and other structures for Google’s transit village.

The transit-oriented development, which is called Downtown West, has won all the necessary development approvals from the San Jose City Council.

“A project of this size requires extensive planning,” Jivan said. “Since Downtown West’s approval last year, we’ve been focused on assembling our project team.”

Google is slated to begin the infrastructure and site preparation this year, according to development experts familiar with the search giant’s plans.

The start of site preparation would be a welcome turn of events since Downtown West is expected to be one of the most consequential projects ever built in San Jose.

The transit village is poised to provide downtown San Jose with a major economic boost. Google intends to employ up to 25,000 workers within the Downtown West footprint.

Downtown West also will feature thousands of homes. Hundreds of those residences will be affordable.

Mountain View-based Google was drawn to the concept of this new neighborhood partly because the western edge of downtown San Jose is an area that is largely underdeveloped.

The area also is peppered by an assortment of older commercial structures, industrial buildings, surface parking lots and vacant parcels.

Plus, Diridon Station is poised to be one of the nation’s busiest transit hubs. The station is a nexus for light rail, Caltrain, Amtrak, Capitol Corridor and the ACE Train. In the future, BART and high-speed rail stops are expected to connect to the downtown San Jose transit complex.

Some of the site preparation work and infrastructure improvements will be very visible and some won’t be. It’s too soon to give a precise timeframe for the actual start of construction for vertical offices, houses and merchant spaces.

As the infrastructure and site preparation work gets underway, Google says it will keep working closely with San Jose residents and municipal leaders on the upcoming phases of the Downtown West neighborhood.

“We look forward to continuing our work with the city and community in this next phase,” Jivan said.
