Chapter 18. General Zoning Ordinance
Sec. 18-108. Vibration Standards
(1) Purpose. The purpose of this Section is to regulate the creation of vibration which adversely affects abutting properties in order to prevent the creation of nuisances and to promote the health, safety, and general welfare of the public.
(2) Applicability. The requirements of this Section apply to all uses and activities which create detectable vibrations, except that these standards shall not apply to vibrations created during the construction of the principal use on the subject property.
(3) Review and Approval. Through the site plan review process (see Section 18-164), the Plan Commission shall review and approve all development on the subject property.
(4) Depiction on Required Site Plan. Any activity or equipment which creates detectable vibrations outside the confines of a building shall be depicted as to its location on the site plan required for the development of the subject property.
(5) Requirements. No activity or operation shall cause or create earthborn vibrations in excess of the displacement values given in Figure 18-108, below.
(6) Method of Measurement. Measurements shall be made at or beyond the abutting lot line or the nearest residential district boundary line. Vibration displacements shall be measured with an instrument capable of simultaneously measuring in 3 mutually perpendicular directions. The maximum permitted displacements shall be determined in each zoning district by the following formula: D = K/f, where D = displacement in inches; K = a constant to be determined by reference to Figure 18-108 below; f = the frequency of vibration transmitted through the ground (cycles per second).
