This <br /> contour defines the noise impact area of the Airport.All land uses located outside this contour are <br /> consistent with the noise compatibility policies of this ALUCP. <br /> Noise Policy 2—Airport Noise/Land Use Compatibility Criteria <br /> The noise compatibility policies set forth in this section shall be used in conjunction with the 20- <br /> year future noise exposure contours depicted on Exhibit 3-2 and noise/land use compatibility <br /> criteria presented in Tablen3-3. <br /> of The compatibility criteria in this section indicate the maximum acceptable airport-related <br /> noise levels,which are measured in terms of CNEL,for a range of land uses. <br /> bf Noise compatibility policies only apply to the identified noise contours. Within the four <br /> noise exposure ranges, each land use type is shown as"compatible", "conditionally <br /> compatible", or"incompatible". The meaning of these terms is provided in Table 3-3. <br /> cf Land uses not specifically listed in Table 3-3 shall be evaluated using the criteria for <br /> similar listed uses. <br /> Noise Policy 3— Residential Land Uses <br /> Residential land uses are considered conditionally compatible in areas exposed to noise levels <br /> between CNEL 60-64 dB only if the proposed use is on a lot of record zoned exclusively for <br /> residential use as of the effective date of this ALUCP. In such a case,the residential land use <br /> must be sound-insulated to achieve an indoor noise level of CNEL 45 dB or lower. The property <br /> owner shall also grant an avigation easement to San Mateo County in accordance with Noise <br /> Policy 5 prior to issuance of a building permit for the proposed building or structure. <br /> SanfCarlosfAirportV 3-6 ESAfAirportsf/130753f <br /> ALUCPfWhitefPape/ Junef2014f <br />
