Summary
Richmond lets an enforcing officer determine a noise violation using maximum decibel (dBA) levels as an alternative to the general noise standard, with the chosen standard being the sole means used for that incident.
It addition to determining noise violations under the standard set forth elsewhere in this chapter, the enforcing officer may alternatively use the maximum decibel ("dBA") levels to determine a violation of this chapter. The standard chosen by the enforcing officer for the specific incident shall be the sole means used to determine if a violation has occurred. Neither standard shall be considered superior, nor controlling, nor preempt the other.
Full Breakdown
Richmond Municipal Code section 9.52.100 allows an enforcing officer, in addition to the general noise standard, to alternatively use maximum decibel (dBA) levels to determine a violation. The standard chosen for a specific incident is the sole means used to decide whether a violation occurred, and neither standard is superior or controlling. A dBA reading offered as a defense must be taken at the same time, location, and conditions with a calibrated meter.
Violations & Fines
Noise exceeding the maximum permitted dBA levels can be cited under RMC 9.52.100 when the enforcing officer applies the decibel standard.
