The purpose of this chapter is to establish minimum safeguards
to protect human health, safety and welfare, as well as property,
by establishing reasonable regulations governing the possession and
use of explosive materials and the removal of rock through chipping,
drilling and other mechanical means. To ensure that the possession
and use of explosive materials does not result in physical injury
or property damage and to establish a balance between the noise and
other quality-of-life issues and adverse impacts of mechanical rock
excavation, the City Council hereby asserts its right to designate
acceptable hours for blasting and mechanical rock excavation operations,
set levels for the ignition and discharge of explosive materials,
limit the number of mechanical rock hammers on a property, limit the
number of blasting and mechanical rock excavation permits issued in
a geographical area in a specific amount of time, and establish acceptable
standards governing consequential vibrations resulting from all blasting
conducted within the City.
