Question: What now occupies the old Dunes golf course that is a 1679700 sqft urban complex?
Context: Lester Park Golf Course is one of two public golf courses located in the port city of Duluth, Minnesota.  The original eighteen-hole golf course was made up the north shore of Duluth, near the Lester Park River.  The golf course was established in 1934.  The other course, Enger Park, is located near the Duluth landmark, Enger Tower, and was established earlier than Lester in the 1920s.  Lester Park is well known around Minnesota for its spectacular beauty and rich history as a golf course because a unique view of Lake Superior is available on 20 of the 27 golf holes.  The original 18 holes have been redone four times since their initial design.  In 1997, Paul Schintz, a former club pro from St. Paul, took over Lester Park as PGA Golf Professional.  In 2003, Schintz became the Director of Golf, overseeing both Lester Park and Enger Park clubhouse operations.  The golf courses were split to a 2 golf pro / 2 contract setup in 2005 with the addition of Steve Anderson to Enger Park Golf Course, with Schintz remaining at Lester Park.  In 2007, the Duluth city council voted to accept a contract with Professional Golf Management, Inc.  The Management company consisted of partners Schintz, as PGA Golf Professional and Jud Crist, Golf Course Superintendent.  The management company now operates both facilities for the City of Duluth, overseeing clubhouse and maintenance operations.  Management Inc. Wing Park Golf Course in Elgin, Illinois is the "oldest and best preserved nine-hole municipal golf course in Illinois."  The course was constructed during a golf course boom in the Chicago area during first few years of the 1900s.  The course was named after William H. Wing, who donated the land for a park in 1902.  When the Elgin and Belvidere Electric Company was built only a few blocks away, Elgin developed the southern portion of the property to a golf course.  The course was developed by Tom Bendelow, a prolific designer who laid out over six hundred golf courses.  Wing Park Golf Course opened on September 5, 1908 and has been in continuous operation since.  The Wing Park Golf Club was organized in 1912 to help manage the property.  The course was listed on the National Register of Historic Places in 2009. A golf course superintendent is a person who professionally manages the labor, time, materials and financial resources needed to care for the turfgrass and landscaped grounds on a golf course.  Golf course superintendents have also been referred to as greenskeepers and turf managers.  Golf course superintendents are concerned with the environmental health of the golf course, the sporting needs of the players and the financial sustainability of the golf club or country club for which they work.  Golf course superintendents communicate the status of the grounds and maintenance resources to members of the club’s management, owners or board of directors, green chairs and committees, golfers, vendors, suppliers, golf professionals, golf course architects and others in the golf industry.  Their management strategies must also align with the golf club business’ environmental and philanthropic role in the community.
