Chula Vista is holding out $400 million worth of incentives to become Amazon’s second headquarters city.

Anticipating Amazon’s Oct. 19 proposal deadline, the Chula Vista City Council OK’d the offers late Oct. 17.

The incentive package includes 85 acres of land, estimated at $100 million, in the city’s Millenia development, as well as 30 years of property tax relief, estimated to be worth $300 million.

Seattle-based Amazon is looking for a site for HQ2, its secondary headquarters.

Chula Vista officials said they could offer Amazon a “shovel ready,” greenfield site that could support more than 8 million square feet of space. Commercial buildings in the South Bay’s Millenia development will have some of the largest floor plates available in Southern California, they added.

In addition, city officials said Amazon would have a say in how Chula Vista develops a proposed university nearby. The city has eyed putting a campus on undeveloped land in its eastern half for a long time.

Also proposed is a rapid transit bus line running between Amazon’s headquarters and San Diego’s downtown core.
