§ 18.40.200. Nuisances.  


Latest version.
  • Nuisance performance standards in the IP district are as follows:

    A.

    Vibration, Heat or Glare. No use shall be permitted which creates vibration, heat or glare detectable by the human senses without the aid of instruments beyond the boundaries of the site.

    B.

    Smoke, Dust, Fumes or Contaminants. No use shall emit smoke, dust, fumes or particulate matter contaminants which are detectable by human senses without the aid of instruments or which violate the standards established by the applicable air quality management district.

    C.

    Odor. No use shall create odors beyond the boundaries of the site which are offensive or are detectable by the human senses without the aid of instruments.

    D.

    Sound. All noise shall be muffled so as not to be objectionable due to intensity or periodicity. Maximum peak sound pressure levels when measured on the "A" scale at the lot line of the property on which the sound is generated shall, except in the case of taxiing aircraft, not exceed a curve drawn through a plot of the following points:

    Maximum Sound Pressure Levels in

    Decibels re: 0.0002 dyne/cm
    Octave Band Center
    Frequency in HZ
    Noise Sources Within 200 Feet
    of All Industrial Park Parcels
    31.5 75
    63.0 72
    125.0 67
    250.0 59
    500.0 52
    1,000.0 46
    2,000.0 40
    4,000.0 34
    8,000.0 32
    16,000.0 30

     

    The sound pressure level shall be measured with a sound level meter and associated octave band analyzer conforming to standards prescribed by the American National Standards Institute.

    E.

    Radioactivity, Electrical Disturbance or Electromagnetic Interference. No use shall be permitted which emits dangerous levels of radioactivity, causes off-site electrical disturbance or creates electromagnetic interference which adversely affects the operation of any aircraft or equipment in the vicinity of or at the Napa County Airport or Skaggs Island.
