Fairfax County supervisors on Monday delayed a vote on the long-awaited overhaul of Springfield Mall after an unresolved issue among landowners knocked the project off course.

County officials and mall owners alike had hoped for a quick rezoning approval that would have allowed the ambitious redevelopment to move forward. The makeover would install new retail, hotel, office and living space on the site of the languishing mall, as well as trails, parks and other improvements.
