Summary
West Sacramento requires an acoustic study for any project whose noise could exceed the City's General Plan noise tables, and mandates a 45 dBA interior standard for new schools, hospitals, churches, and homes near noisy uses.
A. Acoustic Study. An acoustic study shall be required for any proposed project which could create or be subject to a noise that exceeds the levels contained in Tables S-7.1 through S-7.4 in the General Plan.
B. Noise Attenuation Measures. Any project subject to the acoustic study requirements of subsection A, Acoustic Study, may be required as a condition of approval to incorporate noise attenuation measures deemed necessary to ensure that noise standards are not exceeded.
1. New noise-sensitive uses (e.g., schools, hospitals, churches, and residences) shall incorporate noise attenuation measures to achieve and maintain an interior noise level of 45 dBA.
2. Noise attenuation measures identified in an acoustic study shall be incorporated into the project to reduce noise impacts to satisfactory levels.
3. Emphasis shall be placed upon site planning and project design measures. The use of noise barriers shall be considered and may be required only after all feasible design-related noise measures have been incorporated into the project. (Ord. 19-1 § 3)
Full Breakdown
Under West Sacramento Municipal Code Section 17.28.110, any proposed project that could create or be exposed to noise exceeding the levels in Tables S-7.1 through S-7.4 of the General Plan must submit an acoustic study. Where that study is triggered, the City can condition approval on noise attenuation measures, and new noise-sensitive uses -- schools, hospitals, churches, and residences -- must achieve and maintain an interior noise level of 45 dBA. The chapter applies citywide to industrial, commercial, and other uses in place at the time of adoption, with site planning and design measures favored over noise barriers wherever feasible.
Violations & Fines
Noncompliance is addressed through the City's zoning enforcement process under Chapter 17.46; development lacking a required acoustic study or attenuation measures can be denied approval or conditioned before permits issue.
