Full Breakdown
Sec. 8(b) sets receiving land use sound limits using the L10 metric, meaning the level a sound cannot exceed for more than 10 percent of any measurement period of at least ten minutes. m. m. m. Sunday through Thursday. Commercial receiving areas are capped at 65 (dB)A exterior and 55 (dB)A interior at all times. Sec. m. A pure tone or impulse noise, such as a repetitive beep or a bang, gets a stricter 5 (dB)A reduction off both the L10 and maximum limits under Sec.
8(d). Where a noise source can be measured from more than one zoning district, Sec. 8(e) applies the limit of the more restrictive district at the boundary. Measurements follow the procedures in Sec. 9: a calibrated sound level meter, positioned about five feet above ground and at least 25 feet from the source, run for a minimum ten-minute period by personnel trained in a county-approved noise measurement program. Sec. 8(f) puts the burden on anyone contesting a reading to prove the actual level by clear and convincing evidence.
Violations & Fines
Exceeding the applicable L10 decibel limit for more than 10 percent of a ten-minute measurement period is a violation of Sec. 15-8.8, punishable as a second-degree misdemeanor under Sec. 15-8.7 and prosecuted before the Code Compliance Board. Anyone disputing a metered reading carries the burden of proving the true sound level by clear and convincing evidence under Sec. 15-8.8(f).
