Business and civic leaders held a formal groundbreaking Sept. 26 for the multibillion-dollar mixed-use Millenia community in Chula Vista, slated to include 3,000 residential units and related commercial elements.

The master builder is The Corky McMillin Cos., which is building for-sale homes at the site and working with other developers on elements expected to include retail, offices and a 120-room hotel, as the development is built out over the next 10 to 20 years.

McMillin Cos. Chairman Scott McMillin said the 210-acre project, equivalent to about 80 city blocks, is envisioned as a future “City Center of South County.” Plans call for 2 million square feet of office space, 1.5 million square feet of retail, six themed urban parks, bikeways and public promenades.

The company has estimated that Millenia would represent a total investment of about $4 billion by various developers by the time it is fully built out.

Grading on approximately 100 acres has begun, with construction expected to start within 12 months on the first components. Those include a 270-unit apartment community being built by San Diego-based Fairfield Residential, and 214 attached homes being built by McMillin Cos.’ residential division, McMillin Communities.
