Seven foot or greater soundwalls(if allowed by the County)are to be constructed to reduce outdoor noise levels to 60 dB Ldn. Six-to-seven foot soundwalls are to be constructed as an alternative to reduce outdoor noise levels to 65 dB Ldn,provided the applicant can show Fire Safety and that it is not feasible to achieve an outdoor noise level Law of 60 dB Ldn using practical mitigation techniques. Enforcement: To ensure acceptable noise environments for each land Indoor noise levels not to exceed 45 dB Ldn are to be 83 V,D,0(1) Noise use. Y achieved. COA-27 The following exterior noise levels shall be considered acceptable: (a)65 dB Ldn or less for residential COA's development.
