WHAT IS THE CAUSE OF AIRPORT NOISE AND LAND USE PROBLEMS? impacts on people that may be described by such terms as annoyance, The land use and noise problems associated with today's airports have nuisance,disturbance or dissatisfaction. developed over the last half century. Today, rapid changes in urban Economic Impacts development patterns and increased aviation activity have made aircraft noise a major issue. Without proper airport/land use compatibility planning, airport noise levels may become an undesirable by-product of a service that offers In the past, most airports were located away from developed areas. substantial economic benefit for area communities.

The Legal Impacts airport environs usually have good highway accessibility and existing People negatively impacted by airport noise may filedarnage suits against availability of utilities.Therefore,land near the airport becomes economically the airport. The outcome of many of these suits has resulted in court actions more attractive than other areas for subdivision development.Consequently, reducing airport service and/or the payment of large sums of money for the urban outward growth development pressures may cause previously relocation of noise sensitive land uses. larger metropolitan areas such as acceptable land use patterns around the airport to be rapidly converted to Phoenix and Tucson have been involved In noise litigation proceedings in noise sensitive land uses such as residences,schools.churches and hospitals. recent years.
