(a) All components of the demolished structure including concrete floors and block walls shall be hauled from the site. Foundation and utility excavations outside the road right-of-way shall be filled with clean soil containing no refuse or wood. The fill shall be installed and compacted in lifts to obtain a minimum of ninety percent (90%) maximum density at optimum moisture content as determined by a modified proctor test. The Deputy Service Director/Superintendent of Engineering may require on-site testing to assure proper compaction is obtained. The applicant shall be responsible for the costs for testing should it be required and shall supply an adequate sample of the material proposed for backfill well in advance of the scheduled work. Concrete and concrete block may only be used for backfill where it is mixed with granular material so as not to alter the compactability of the solid when it is crushed to pass one hundred percent (100%) through a three-inch sieve. (Ord. 2002-106. Passed 11-6-02.)
(b) The filing of such excavation shall not be required when a building permit has been issued for a new building on the site and the construction thereof is to be started within sixty days after completion of the wrecking operation. However, in such event, the holder of the building permit shall surround such excavation with a substantial fence protecting all sides to a height specified by the Building Inspector. All adjacent streets, alleys and sidewalks shall be kept free and clear of all rubbish, refuse and loose material resulting form the wrecking and removal operations. (Ord. 1999-96. Passed 8-11-99.)
