All fills shall be compacted to a minimum of ninety percent of maximum density as determined in the laboratory by the American Society for Testing Materials D-1557-91 test or modification thereof approved by the County Official, provided that the compactive energy of the test shall not be less than 35,000 foot-pounds per cubic foot. Field density shall be determined by the American Society for Testing Materials D-1556-90 or D2922-91 method, or an equivalent test approved by the County Official. Lower degrees of compaction may be permitted by the County Official after he or she receives a soil engineer's report certifying that the soil engineer has investigated the property, made soil tests, and that in the engineer's opinion such lower degree of compaction will be adequate for the intended use of the property which use shall be described in the report.
