Table N-1 Interior and Exterior Noise Standards
The City’s primary focus is to minimize noise problems in areas sensitive to noise because the majority of land in Santa Ana is fully established. The City emphasizes mitigation measures to deal with existing noise problems, as well as the prevention of new noise problems. Noise levels are managed through proper design and location of mobility and noise systems in relationship to noise-sensitive land uses, and establishment of appropriate noise emission or insulation standards for the various land uses.
The City adopts the standards and guidelines for noise levels for land uses as displayed in Table N-1. Residential uses should be protected with sound insulation over and above what is provided by normal building construction when they are constructed in areas with noise levles higher than 60 dB CNEL (community noise equivalent level).
