San Diego-based Sunroad Enterprises announced Aug. 16 that it plans to build a 500,000-square-foot retail center in Otay Mesa.

Subject to city planning approvals, Sunroad Otay Plaza would be built on a 50-acre site at the intersection of state Routes 905 and 125. It would include several big-box retailers with spaces larger than 100,000 square feet.

Curt Stephenson, president of company division Sunroad Ventures Inc., said lease negotiations are under way and none have been finalized, although Sunroad is looking to attract tenants along the lines of Costco Wholesale, Target and home improvement chains Home Depot and Lowe’s.

Construction is expected to begin in fall 2012, with an opening tentatively planned for fall 2013. Tom Story, Sunroad Enterprises’ vice president of development, said the company has projected that the center when fully operational will generate approximately $2 million in annual sales tax revenue for the city of San Diego.

City officials are discussing an Otay Mesa community plan that would change the area’s image from a warehouse commercial district to add retail, consumer services and residential units.
