The city and two local developers still are working on an agreement for a $250-million hotel complex including a JW Marriott near White River State Park. The parties had hoped to reach agreement by April 1. There are no hangups preventing the deal, only many details to work out, Barbara Lawrence, executive director of the Indianapolis Local Public Improvement Bond Bank, tells Property Lines. The details include a new look for the 1,000-room hotel. The developer, a partnership of Merrillville-based White Lodging Services Corp. and Indianapolis-based REI Real Estate Services, could get city incentives worth about $48.5 million.
