Las Vegas – The owners of Lake Las Vegas, a 3,592-acre residential and resort development in southern Nevada, have filed for Chapter 11 bankruptcy protection. The filing Thursday in U.S. Bankruptcy Court in Las Vegas came about six months after LLV Holdco LLC, a subsidiary of Las Vegas-based Atalon Group, took over ownership and management of the luxury community in Henderson from owners who defaulted on USD 540 million in loans.
