A pre-blast survey involves the documentation of the property condition prior to the proposed quarry. It is a written record of what a home and other structures (if present) on the property is like before any quarrying occurs at the project site. It is done by a certified, independent professional. Having a record of the pre-blast condition of a property is a good due diligence measure for both the homeowner and the quarry operator. However, property owners retain the right to waive their participation in this due diligence program being offered by the Hammond River Holdings.
