Shaping the New Capital of the Inland Empire

We're creating a permanent, immersive center for a region that already has the traffic, the events, the households and the travelers. Capital City is where all of it comes together.

The destination gap

Ontario already gathers here

Ontario's arena, airport, convention center and 3,000+ residential units already sit within a mile of each other. People arrive by car, by flight, by event and by habit. Capital City gives them a reason to stay.

Capital City is the walkable center those engines deserve: a permanent place to gather, dine, stay and return.

Why here

Four engines, one address

Each one brings a different audience on a different rhythm. Together they fill the week, not just the weekend.

A market in motion

The Inland Empire now outpaces Los Angeles County on median household income, while Ontario keeps a younger local market.

04 · The opportunity

A center to gather, dine, linger and return

The market already has the events, the households and the travelers. Capital City gives them somewhere to stay once they arrive.

A market with its own purchasing power

Younger and higher earning

The Inland Empire earns more than Los Angeles County and skews younger. Capital City is being built for exactly that consumer market.
