SAN JOSE — The city of San Jose has sold off several big chunks of land near the airport, a move that could bolster a major expansion of an office complex that’s already landed some large tech companies as tenants, municipal officials confirmed Tuesday.

The developers paid San Jose $24.8 million for the 12.7 acres of land, which are next to the main Coleman Highline development and near 1123 Coleman Ave., according to Santa Clara County property records and city documents. The deal was completed Dec. 14.

“The sale of these properties could eventually allow for a more dense development at Coleman Highline,” said Nanci Klein, San Jose’s director of real estate. “The properties are all adjacent to the development.”

The properties were bought by affiliates of Coleman Airport Partners, the realty partnership that includes Hunter Properties, which is developing the Coleman Highline office, retail, restaurant and hotel complex

In January of this year, tech company 8×8 leased 162,000 square feet, enough space for an estimated 810 workers. But that rental deal was only the start for Coleman Highline, whose office buildings were designed by San Francisco-based Gensler.

Roku during 2018 completed multiple agreements that revealed the maker of digital media players had rented 570,000 square feet in the development.

“We are seeing a lot of good momentum with the project,” said Curtis Leigh, director of development with Cupertino-based Hunter Properties.

In addition, a 175-room hotel that would operate under one of the Marriott brands has been proposed for a site at Coleman Highline.

The city has long anticipated that the site could become a big development and a huge jobs hub.

“Since 2005, the city has envisioned an amenity-rich jobs environment” at the Coleman Highline complex, Kim Walesh, a deputy city manager, said in a memo circulated among San Jose council members. “Full build out of the site could accommodate 6,000 jobs.”

Flush with cash from the property sale, city officials intend to scout for sites to construct new parks and recreation facilities, the city memo states. Potentially, $19.7 million of the $24.8 million would be used to ensure completion of the Agnews Soccer Complex and other parks projects, according to the memo.

The additional land now owned by the Coleman Highline developers will allow them to provide much more parking for office tenants, as well as hotel, retail and restaurant patrons and to avoid parking conflicts related to soccer games or other events at the nearby Avaya Stadium.

More tech companies may be coming to the development.

“Hunter Properties is talking to other potential large tenants,” Klein said.
