Beach Park is the home to the South Beach section of Illinois Beach State Park, which is otherwise located in Winthrop Harbor. The beach was originally part of Camp Logan, a rifle range developed by the Illinois National Guard in 1892. In World War I and World War II it served as a rifle range for the Great Lakes Naval Training Station. The range remained in operation until 1973, when it was transferred to the Illinois Department of Conservation. In 1950, the Illinois Dunes Preservation Society was established to maintain the natural qualities of the beach. With the help of the Illinois Department of Conservation the area south of Beach Road was established as the state's first natural preserve. The northern beach, between Beach Road and the Wisconsin state border, was obtained between 1971 and 1982. The south beach is now home of the Illinois Beach Resort and Conference Center. The North Point Marina is at the north beach. This is Illinois' newest and largest marina and the largest freshwater marina in the United States. On May 9, 2000, the area encompassing Illinois Beach State Park and North Point Marina was officially designated as the Cullerton Complex in honor of William J. Cullerton, Sr., war hero, avid environmentalist and long-time friend of conservation.
The village of Beach Park is policed by the Lake County Sheriff's Office. The village has contracted with the Sheriff's Office to provide additional Deputy Sheriff personnel to patrol the village during the day. These deputies are able to call on the resources of multiple deputies, and the members of the Zion, Waukegan and Gurneepolice departments should an emergency require it. The village has allowed the deputies to use the Village Hall as a small sub-station, which limits the time deputies are out of the area. Previously, the deputies had to return to Waukegan or Libertyville for paperwork issues. Beach Park is provided fire and EMS protection 24/7 by the Beach Park Fire Protection District, the Winthrop Harbor Fire Protection District and the Newport Township Fire Protection District. The Beach Park Fire Protection District provides 90% of the village with fire and EMS services. All three districts, have signed Auto Aid Agreements with each other which is assistance dispatched automatically by contractual agreement between two communities or fire districts. In early 2006, the Beach Park Fire Protection District received voter support for a nominal tax increase. This increase made full-time firefighter/paramedics a reality. The department was also able to lower the Insurance Services Organization rating to a 3. This is one of the lowest in the area and saves residents on homeowners and renter's insurance. The Beach Park Fire Department is taking positive steps by replacing older fire equipment. This will ensure that the residents receive good fire response by newer apparatus. All departments which provide fire and emergency medical services are part of the MABAS Mutual Aid program. This program, funded by member agencies, provides assistance from the local region all the way to national resources.
