Goal NOI-1

Goal NOI-1:

Residents and employees of South San Francisco are exposed to acceptable noise levels.

Policy NOI-1.1: Ensure new development complies with Noise Compatibility guidelines.

Ensure that all new development within the city complies with the Land Use/Noise Compatibility guidelines shown in the table below.

  • Action NOI-1.1.1: Enforce Exterior and Interior noise limits.

    Enforce the standards of the table below Land Use/Noise Compatibility Matrix, which specify acceptable exterior and interior noise limits for various land uses throughout the city.

  • Action NOI-1.1.2: Incorporate noise compatibility conditions of approval.

    Continue to assess projects through the subdivision, site plan, conditional use permit, and other development review processes and incorporate conditions of approval and mitigation measures that ensure noise compatibility where appropriate.

  • Action NOI-1.1.3: Require noise study in applicable areas.

    Require a noise study to be performed and appropriate noise attenuation to be incorporated to reduce interior noise levels to 45 dB CNEL or less prior to approving any multifamily or mixed-use residential development in an area with a CNEL of 65 dB or greater.

  • Action NOI-1.1.4: Enforce Noise Insulation Standards.

    Continue to enforce the noise insulation standards of the State of California Administrative Code, Title 24 and the Uniform Building Code, Chapter 35 for residential development.

  • Action NOI-1.1.5: Require noise control for new developments.

    Require the control of noise at the source through site design, building design, landscaping, hours of operation, and other techniques, for new developments deemed to be noise generators.

Policy NOI-1.2: Enforce Noise Performance Standards.

The City enforces the Noise Ordinance noise performance standards.

  • Action NOI 1.2.1: Update Municipal Code section related to the Noise Ordinance.

    Update the Noise Ordinance in the South San Francisco Municipal Code to establish standards for permissible construction hours, and controls related to other potential nuisances such as music, dogs, special events, and mechanical/sound equipment; and encourage enforcement and penalties for violations of the Noise Ordinance. The update should not interfere with the regular course of business in commercial and industrial zones.

    • General Activity Noise Performance Standards:

      Establish general noise performance standards for the City’s established land use zones.

    • Construction Noise:

      Continue to restrict construction activities to acceptable time periods. Consider constructing temporary sound walls surrounding construction sites during construction.

    • Special Event Noise:

      Allow single-event occurrences at specific sites subject to special permit conditions which alleviate noise to the greatest extent possible. Limit the permissible hours for special single events and the number of special single events that are allowed to take place each year.
