Restricted Airspace

• Kalamazoo/Battle Creek International Airport (AZO) Class D airspace directly affects Portage. The airport is on the western edge of Portage and its Class D airspace extends approximately 4.4 NM from the airport up to 3,000 feet MSL. Western and central Portage operations fall within AZO Class D, requiring LAANC authorization. The airport handles regional commercial flights and corporate aviation for Pfizer and Stryker operations. Commercial operators in Portage should check LAANC grid squares for most locations in the city.
• W.K. Kellogg Regional Airport (BTL) Class D airspace in Battle Creek handles Air National Guard A-10 Warthog operations. Northeastern Portage operations near the Gull Road corridor may be affected by BTL military flight patterns. The A-10 training operations create additional airspace considerations including potential temporary flight restrictions during military training exercises. Operators should check NOTAMs for BTL military activity.
• Pfizer Global Research and Development campus in Portage has enhanced security considerations for commercial drone operations. The Pfizer campus is one of the largest pharmaceutical research facilities in the United States and includes research laboratories, manufacturing facilities, and corporate offices. Operations near the Pfizer campus should coordinate with corporate security. Pharmaceutical facility construction and expansion creates ongoing demand for drone aerial imaging and inspection services.
• The I-94 and US-131 interchange complex near Portage has critical infrastructure considerations. MDOT has an active drone inspection program for bridge and highway infrastructure. The I-94 corridor through Portage is a major east-west commercial corridor connecting Detroit to Chicago. The Westnedge Avenue and Oakland Drive bridges over I-94 are major infrastructure assets requiring periodic inspection. The Portage Road corridor has ongoing construction activity.
• Portage is known for its extensive park system with over 1,200 acres of parks and nature preserves. The Portage Creek Bassetage Trail system, the West Lake Nature Preserve, and the Portage Bog Preserve restrict unauthorized drone flights over nature preserve property. Environmental monitoring of the Portage Creek and Kalamazoo River watersheds creates demand for drone aerial imaging services. The city's extensive trail system and wetland areas create environmental monitoring demand.
