Michigan and a squadron of P-3 Orions which had the mission of East Coast antisubmarine warfare. The rationale for basing the squadron there was that so many reserve staff were in the central United States, and it was convenient to base the facility near the staff. As a 1−2 hour checklist had to be executed before scanning the seas, there was actually little dead time in the flight to the coast. The base consisted of 1 million cubic yards (800,000 m3) of concrete, of runways and 108 U.S. Navy buildings. The only two buildings that are left from the naval airstation are the pilot tower and the chapel. The rest has been renovated into "The Glen Town Center" which is a shopping center. The Glen In 1995, the base was closed as part of the Base Realignment and Closure military restructuring process. The land was deeded back to Glenview by the U.S. Department of Defense. A reuse plan was completed by the Village of Glenview in 1995 and updated into a master plan by Skidmore, Owings & Merrill in 1998. The village then assumed the role of Master Developer. The development was named "The Glen" in 1999. It comprises approximately 15% of the area of Glenview. It contains new homes, offices, and shopping centers, including a movie theater and The Glen Town Center. Among other amenities, it includes a lake, soccer fields, tennis courts, walking and biking trails, two golf courses, Kohl Children's Museum, the Glenview Park District Park Center, Attea Middle School, and the North Glenview Metra station.
