§ 12-45. Compaction permit within limits.  


Latest version.
  • (a)

    It shall be unlawful for any person to perform dynamic compaction within the territorial limits of Broward County without first obtaining a compaction permit as hereinafter provided by this section; provided that in any event it shall be unlawful for any person to perform dynamic compaction which:

    (1)

    Would result in a vector sum particle velocity in excess of those limits set forth in Appendix B of the U.S. Bureau of Mines Report No. 8507, as set forth in Exhibit "A" of this ordinance, when measured on the ground at the nearest building or structure not owned by the permittee, or at a location identified by the seismologist of record and the Division director, or designee;

    (2)

    Would result in an air overpressure level in excess of the following, when measured at the nearest building or structure not owned by the permittee:

    2-Hz high-pass system ..... 133 dB;

    or

    (3)

    Would utilize a weight in excess of ten (10) tons.

    Deviations from the limits set forth in this section shall be accepted by the director of the Division, or designee, upon certification by the seismologist of record that a higher peak particle velocity will not exceed the guidelines set forth for thresholds of damage per the U.S. Bureau of Mines. Dynamic compaction that results in greater vector sum particle velocity or airblast than described above would constitute a public nuisance and, therefore, be detrimental to the public health, welfare, and safety of this County.

    (b)

    Peak particle velocity shall be measured as the true vector sum (Resultant Peak Particle Velocity) in three (3) mutually perpendicular planes at one instant of time. Air overpressure shall be defined as airborne pressure waves resulting from the dynamic compaction operation. (Exh. "A" to Ord. No. 2003-11 is not set out herein but is available at the Records, Taxes, and Treasury Division.)
