( 4.14-12-10-80; Ord. 00-18(3), 6-14-00) (Repealed 6-14-00) (Repealed 6-14-00)



The produce of displacement in inches times the frequency in cycles per second of earthborne vibrations from any activity shall not exceed the values specified below when measured at the points indicated. METHOD OF MEASUREMENT

Earthborne vibrations shall be measured by means of a three component recording system, capable of measuring vibration in three mutually perpendicular directions. The displacement shall be the maximum instantaneous vector sum of the amplitude in the three directions. MEANING OF TERMS

Vibrations means the periodic displacement of oscillation of the earth.


Area of Measurement


Type of vibration


At residential district boundaries




At other lot lines

within district






Impulsive (100 per

minute or less)





Less than 8 pulses

per 24 hours






4.14.3 GLARE

No direct or sky reflected glare, whether from flood lights or from high temperature processes such as combustion, welding or otherwise, so as to be visible beyond the lot

Each future occupant of an industrial character shall submit to the county engineer as precedent to issuance of a zoning compliance clearance a certified engineer's report describing the proposed operation, all machines, processes, products and by-products, stating the nature and expected levels of emission or discharge to land, air and/or water or liquid, solid or gaseous effluent and electrical impulses and noise under normal operations, and the specifications of treatment methods and mechanisms to be used to control such emission or discharge. The county engineer shall review the applicant's submittal and make comment and recommendation prior to final commission action on the site development plan. (Amended 9-9-92)
