Burien city officials have postponed plans to buy back three acres from a developer while they consider its new plan for developing the site.

Developer Harbor Urban was to build condos and retail on the property acquired from the city in 2007 as part of Burien Town Square, a public-private initiative to revitalize Burien's downtown.

The Burien City Council, tired of waiting, voted earlier this month to exercise a clause in its contract with Harbor Urban and buy the land back.

The sale was to close Wednesday. But City Manager Mike Martin said Tuesday the closing has been pushed back to July 18 while Harbor Urban presents a revised proposal.

A meeting is scheduled Wednesday, Martin said. He said Harbor Urban hasn't submitted its new plan yet, but the firm has told city officials it plans to complete the project by mid-2013.

A Harbor Urban spokesman could not be reached.
