OAKLAND — Downtown Oakland would land 4,600 new jobs through a major new Uptown district project proposed by the developer who brought an Uber headquarters complex to the East Bay city, developers said Tuesday.

All told, about 870,000 square feet of offices, 50,000 square feet of retail and 388 residential units would be built as part of the project, which is being dubbed Eastline.

“We see tremendous potential in downtown Oakland; we have always seen that,” said Andrew Haydel, a principal executive with Lane Partners. “With the Eastline project, we are fulfilling the needs of Uptown Oakland.

The project, which would rise on 3.3 acres in Oakland, is bounded by Broadway, 21st Street, Telegraph Avenue and 22nd Street.

“The Eastline project will bring continued retail, economic and residential revitalization to one of our city’s core arteries, helping to create job opportunities and much-needed expansion of our housing supply,” Oakland Mayor Libby Schaaf said Tuesday.

It would be near the Uptown Station office and retail complex that will serve as a co-headquarters for tech upstart Uber, a ride-hailing service.

“We are filling the need for more active and vibrant retail, and we would like to bring new companies and new jobs into Oakland,” Haydel said.

The project’s creators believe that Eastline, a joint venture of Lane Partners and local developer Alan Dones, could be a game-changer for downtown Oakland.

“The Eastline project will be an important and transformative piece of the ongoing growth in Oakland,” said Dones, who is managing partner of Strategic Urban Development Alliance.

The new mixed-use complex could bring far-reaching changes to Oakland, the developers said.

“We’ve specifically focused on sustainable design, supporting local arts and culture and providing vital office, housing, retail space and quality jobs,” Dones said.

Nevertheless, the developers concede that the location of the project above a local BART station presents significant challenges, even though transit sites are generally deemed desirable.

“The BART tunnels run directly below the EASTLINE site,” according to posts on the Eastline.org site. “This is a boon for transit options but does create design challenges. Construction of any structures above or near the tunnels requires costly engineering measures to avoid placing weight, or lateral stresses on the tunnels.”

Another significant obstacle for the builders: The project would erase a considerable amount of parking now being used for people who visit Uptown, which has evolved into a bustling and eclectic district of restaurants, nightclubs, entertainment venues and arts outlets. Parking for the Paramount and Fox theaters would be impacted.

“Any development on this site must include provisions for replacing this parking,” according to Eastline.org.

The 50,000 square feet of retail are expected to bring an array of new merchants to the increasingly busy downtown Oakland.

“We will have an opportunity with the retail to bring in a combination of both local retailers as well as attract some national brands,” Haydel said.

The developers also vowed to benefit Oakland residents and businesses.

At least 50 percent of the businesses involved in the development will be Oakland-based, 25 percent at most will be larger local businesses and 25 percent or more will be small, local Oakland businesses, the developers said.

During the construction phase, at least 50 percent of the project’s work hours will be completed by Oakland residents and at least 50 percent of apprentice work hours on the project will be completed by Oakland residents, the Eastline venture said.

“There is a very vibrant arts and entertainment scene, as well as great food and beverage services, in Uptown,” Haydel said. “There is great weather and excellent transit access. Everything points to a great future for Oakland.”
