COSTA MESA

The Segerstrom family has announced it would add more than 900 homes and scale back office space in an effort to win more support from nearby homeowners for its South Coast Metro Home Ranch development in Costa Mesa.

Planning Commission hearings on the project, which were originally scheduled for next week, have been postponed until Aug. 28 to give the public and city officials time to study the changes.

The 90-acre site is a lima bean field bordered by Sunflower Avenue, the San Diego Freeway, Fairview Road and Harbor Boulevard.

The city designated the land for homes and small industry. But C.J. Segerstrom & Sons is asking for permission to build a 17-acre Ikea furniture store and 950,000 square feet of office space there.

Segerstrom’s original plans called for almost 2 million square feet of office space, with some offices standing eight stories high. In the new plans, offices are no taller than five stories.
