SAN JOSE — Developers have submitted new plans for what would be an iconic office tower near downtown San Jose’s Tech Museum of Innovation and the Center for the Performing Arts, part of what’s emerging as a major revamp of the city’s cultural district.

The office tower, consisting of 19 stories and a mezzanine level, would rise at 200 Park Ave. in San Jose, potentially one of multiple projects designed to help connect the core of downtown with a proposed Google transit village to the west near the Diridon train station.

The builder of the proposed tower at the corner of Park Avenue and South Almaden Boulevard is J.P. DiNapoli Cos., a veteran developer long active in downtown San Jose and other Bay Area cities.

“We hope that this project will help create an active connection that goes all the way from San Jose State University to the Guadalupe River,” said John DiNapoli, president of developer J.P. DiNapoli.

The proposed tower, with a striking split design, would total 740,000 square feet, according to documents on file with San Jose city planners. A complex of that size could accommodate potentially 3,700 office workers.

“We think the design has evolved very nicely,” said Peter Larko, an executive with the DiNapoli firm.

One of the key elements is a paseo along Park Avenue that would help create connections to link the east side, west side and core parts of downtown San Jose.

“We will make sure that the building isn’t a fortress and that it’s connected to the surrounding area,” DiNapoli said. “We are going to activate the ground floor of the tower and the paseo next to it.”

Other potential major projects may sprout across the street and adjacent to the proposed Park Avenue project.

Due north is CityView Plaza, which developer Jay Paul bought July 23 for $284 million, as revealed by this news organization.

The CityView complex of older office, restaurant and retail buildings and is deemed ripe for development, including a bulldozing of some or all of the choice site bounded by West San Fernando Street, South Almaden Boulevard, Park Avenue and South Market Street. Several downtown property experts believe 1 million square feet or more of modern buildings could emerge on the CityView parcel.

Directly to the east is the Museum Place project, which would replace the aging Parkside Hall building with a new development led by real estate entrepreneur and venture capitalist Gary Dillabough.

“The developer (Gary Dillabough) recognizes that downtown San Jose has a limited supply of Class A office in a prime location close to Diridon Station,” according to a memo circulated in June by Kim Walesh, San Jose’s economic development director. “As a result, the developer has indicated an intention to focus on office, retail and the Tech Museum expansion space.”

“We really want to get this right,” DiNapoli said. “The interface from the public area outside to the general lobby of the building is going to be seamless.”
