Excavation, removal, stripping, or mining of aggregate quantities of less than 50 cubic yards on any one general site requires no formal approval. Where the excavation, removal, stripping, or mining of soil is in quantities in excess of 50 cubic yards but less than 1,000 cubic yards, application must be made to the Building Inspector for a miscellaneous soil removal permit. Where special circumstances exist which require the excavation, removal, stripping, or mining of soil in excess of 1,000 cubic yards, but less than 5,000 cubic yards, a permit may be granted by the Board for such removal without a public hearing. However, where the excavation, removal, stripping, or mining exceeds 5,000 cubic yards, then a public hearing will be necessary and the permit granted shall indicate the approximate quantity of soil to be removed, the purpose of removal, and the location of the site of removal. The permit shall also specify that, upon completion of excavation, exposed subsoil shall be graded and covered with loam to a minimum depth of six inches and that the removal is to be controlled by the appropriate section of § 195-5.7, Operating standards. It is further provided that, except where removal under this section is done in connection with the formation or enlargement of a pond, excavation shall not be permitted below the mean grade of the street or road serving the property. The excavation of said pond in any event shall not be such as to change the direction or flow of a watercourse or to cause surface water to gather as a sump or swale. Excavations for burying large rocks and stumps shall immediately be backfilled for safety reasons. Failure to meet the requirements of this section shall be deemed a violation of this Zoning Bylaw.
