This portion of the city's code restricts vibration from machines, animals, or devices (or any combination thereof) from producing vibration that exceeds the specified, measurable noise limits (as summarized in Tables N-4 and N-5, below). In general, this type of regulation is aimed at controlling stationary or on-going vibration sources that are established (in both location and periodicity). Such sources might include, for example, out-of-balance, mounted machinery, impact-intensive manufacturing equipment, or heavy construction processes. Such objective criteria give the city's enforcement officers the capability of demonstrating a measurable violation while using the defined enforcement procedures to document potential violations and to implement penalties (see also Section 9.36.050).
