article 2 design and development standards - Spartanburg County

(2) Diminish the ability of pilots to distinguish between airport lights andother lights;(3) Result in glare in the eyes of pilots using the airport;(4) Impair visibility in the vicinity of the airport; and create bird strikehazards, or otherwise in any way endanger or interfere with thelanding, takeoff, or maneuvering of aircraft using the airport.Section 2.04-5Use RestrictionsTable 8 establishes the types of land uses which are compatible within andwhich may be permitted in each zone, based upon its respective tolerance fornoise.Future development within each zone shall be governed by Table 8, whichassigns use compatibility by zone, based on the following:(1) No New Development: A clear incompatibility exists between futuredevelopment and unavoidable aircraft noise.(2) Noise Restrictions Applicable: Potential incompatibility exists due tonoise exposure from proximity to a runway which can be avoided ifcertain noise attenuation restrictions are met, as required by thissection.(3) No Use Restrictions: A clear compatibility exists between theproposed land use and airport.Section 2.04-6Noise RestrictionsNoise restrictions shall apply within the zones identified by Table 8.Where permitted within such zones, residential dwellings and portions ofbuildings where the public will be received, shall be structurally designed andconstructed to achieve an outdoor to indoor Peak Noise Level Reduction (NLR)of at least 30 Db (decibels). All other permitted uses and structures shall beexempt from this Section.Normal construction can be expected to provide an NLR of 20 Db, thus theactual required reduction is only 10 Db. Lowering the NLR shall be achievedthrough incorporation into the design and construction of all proposed uses,sound insulation materials and methods for improving acoustic insulationperformance.2-49
