Ordinance No. 2003-86 (1) A report shall be submitted from a certified testing laboratory contasning sufficient records and data to establish the character of the soil. Such records sha11 describe the soil conditions found to a depth of at least five feet (5') below the deepest point proposed for the installation of the stone bed or dissipation wells. The report shall include information regarding the level of the water table and soil permeability. (2) The stone bed shall be located a minimum of twenty feet (20') from any building or ten feet (10') from any property line or sanitary sewer easement. (3) An approved filter fabric shall cover the top and sides of the stone bed. (4) The required volume of the stone bed shall be calculated using approved terms for coefficient of runoff, drainage area, storm intensity and time of concentration. The porosity ratio shall be 0.33 to figure net volume from the gross volume. (5) An observation well shall be required for inspection purposes. The location and diameter shall be approved by the Engineering Department. The observation well shall be as deep as the deepest part of the stone bed. Perforated pipe may be approved for use m an observation well. (6) The infiltration basin sha11 have a sump pump to discharge excess water to an approved storm sewer or ditch. (c) All storm water flow from the proposed development, including flows from upstream areas passing through, and further including increased flow attributable to changes in time of concentration or changes in the former runoff factor (imperviousness), shall be conveyed to the proper storage facility end outlet for the entire tnbutary area via a natural channel or pipe/culvert either or both of which shall be improved so as to be of adequate capacity.
