Theresponsibility for determining the acceptable and permissible land uses and the relationship betweenspecific noise contours rests with the local authorities. FAA determinations under Part 150 are notintended to substitute federally determined land uses for those determined to be appropriate by localauthorities in response to locally determined needs and values in achieving noise-compatible land uses.Key: Y(yes): Land use and related structures compatible without restrictions. N(no): Land use andrelated structures are not compatible and should be prohibited. NRL noise level reduction (outdoor toindoor) to be achieved through incorporation of noise attenuation into the design and construction ofthe structure. Land use and related structures are generally compatible; measures to achieve an NLRof 25, 30, or 35 dB must be incorporated into the design and construction of the structure.
