PROVO — Provo officials announced today plans to build a new $45 million shopping center.

Target, Petsmart, Sports Authority and Circuit City are among the stores that have signed letters of intent to open at the East Bay center, which has been named the Southgate Shopping Center.

The 59-acre Southgate Center will be built on the southeast corner of 1860 South and University Avenue, officials said at a 3 p.m. announcement.

The center a Boyer Company development will have 459,000-square-feet of retail space and 225,000-square-feet of office space. By comparison, the Provo Towne Centre Mall has 800,000-square-feet of leasable space.

Provo City owns the 59 acre parcel involved and will sell its interest in the property to the Boyer Company under the terms of a developer agreement, according to a statement issued on Provo's Web site.

"As a part of the purchase agreement, the city will be responsible to provide rough grading of the site to prepare it for development, removal of lakes and replacement of designated wetlands in the area," the statement says. "Several holes of the current Reserve at East Bay golf course are located on this parcel, which will necessitate redesign of the golf course.

The development of the Southgate Center will require the elimination of the current executive nine-hole golf course at the Reserve at East Bay, according to the statement.

The remaining portion of the course built atop the city's old landfill will be reconfigured in two phases to continue to allow 18 holes of play at all times during and after construction.

A first phase will involve moving four holes to the location of the existing executive course. A second phase will build four new holes on the former Kuhni property with a new signature island hole.

Other changes to the course also are planned, officials said.

Construction on the center is scheduled to start in August 2008. It's expected to open the following summer.
