In <br />this publication the Land Use Guidance Zone (LUG) system is <br />introduced as an approach to airport noise evaluation and <br /> <br />compatibility land use planning. <br /> <br />The LUG system is a uniform noise evaluation technique which <br />directly relates to land use compatibility planning and which <br />constitutesla :single system for determining the impact of noise <br />upon individuals resulting from the aircraft operations at an <br />airport. This system utilizes the common noise estimating <br />methodologies as input and translates these, using a series of <br />noise quali~y zones, into categories of land use compatible or <br />incompatible with the existing and forecast aircraft noise <br /> <br />impacts at a particular airport. <br /> <br />iA Guide for Land Use Planning Around Airports in Wisconsin, <br />WI/DOT Division of Aeronautics, 1976. <br /> <br /> <br />
