These guidelines were promulgated in 14 Code of Federal Regulations (CFR) Part 150. These guidelines, reproduced here as Table A-1, Land Use Compatibility Guidelines – 14 CFR Part 150 , show the compatibility parameters for residential, public (schools, churches, nursing homes, hospitals, libraries), commercial, manufacturing and production, and recreational land uses.  \nThe Part 150 guidelines are the basis for defining areas potentially eligible for Federal funding through the Airport Improvement Program (AIP) . The Airport Improvement Handbook states, “Noise compatibility projects usually must be located in areas where noise measured in day-night average sound level (DNL) is 65 decibel (dB) or greater.” 1 Federal funding is available at noise levels below 65 DNL if the airport operator (Sponsor) determines that incompatible land uses exist below 65 DNLand the FAA concurs with the Sponsor’s determination.  \nAs shown in Table A-1 , all land uses within areas below 65 DNL are considered to be compatible with airport operations. Residential land uses are generally incompatible with noise levels above 65 DNL. In some areas, residential land use may be permitted in the 65 to 70 DNL with appropriate sound insulation measures implemented. This is done at the discretion of local communities. Schools and other public use facilities located between 65 and 75 DNL are generally incompatible without sound insulation. Above 75 DNL, schools, hospitals, nursing homes, and churches are considered incompatible land uses. The information presented in Table 4-1 is meant to act as a guideline. According to 14 CFR Part 150, “Adjustments or modifications of the descriptions of the land-use categories may be desirable after consideration of specific local conditions.”2  \n1 FAA Order 5300 .38C, Chapter 7, paragraph 706.  \n2 14 CFR Part 150, Part B Noise Exposure Map Development, Section A150 .101 Noise contours and land usages, paragraph (c) .  \nTable A-1 Land Use Compatibility Guidelines – 14 CFR Part 150  \nYearly Day-Night Average Sound Level (DNL) in Decibels  \n\n|  | Below\u003Cbr>65 | 65-70 | 70-75 | 75-80 | 80-85 | Over 85 |\n| --- | --- | --- | --- | --- | --- | --- |\n| Land Use |  |  |  |  |  |  |\n|  |  |  |  |  |  |  |\n\nRESIDENTIAL  \n\n| Residential, other than mobile homes and transient lodgings | Y | N1 | N1 | N | N | N |\n| --- | --- | --- | --- | --- | --- | --- |\n| Mobile home parks | Y | N | N | N | N | N |\n| Transient lodgings | Y | N1 | N1 | N1 | N | N |\n\nPUBLIC USE  \n\n| Schools, hospitals, nursing homes | Y | 25 | 30 | N | N | N |\n| --- | --- | --- | --- | --- | --- | --- |\n| Churches, auditoriums, and concert halls | Y | 25 | 30 | N | N | N |\n| Governmental services | Y | Y | 25 | 30 | N | N |\n| Transp","cbCairpRUZQxvjS6","https://ap.wps.com/l/cbCairpRUZQxvjS6","pdf",488260,14,"English","# Appendix A Applicable Laws, Regulations, and Policies\n## A.1 Federal Laws and Policies Related to Noise/Land Use Compatibility\n## Table A-1 Land Use Compatibility Guidelines – 14 CFR Part 150\n## Key to Table A-1","[{\"question\":\"What purpose does Appendix A serve for airport noise planning?\",\"answer\":\"Appendix A provides information applicable to airport noise compatibility planning and the analysis of aviation noise for the airport program.\"},{\"question\":\"How are DNL thresholds used to determine funding eligibility in the appendix?\",\"answer\":\"Noise compatibility projects usually must be in areas where DNL is 65 decibels (dB) or greater.
