No structure, except piers, docks and retaining walls shall be placed at an elevation so that the lowest floor, including basement floor, is less than three feet above the highest known water level, or less than one foot above the 100-year regulatory flood protection elevation, if determined, of any adjacent lake, pond, river, watercourse or wetland. If sufficient data on known high-water levels is not available, the elevation of the line of permanent aquatic vegetation shall be used as the estimated high-water elevation. When fill is required to meet this elevation, the fill shall be allowed to stabilize and construction shall not begin until the property has been inspected by the Building Official. If requested by the Building Official, the ground water table elevation shall be determined by a licensed soils engineer using soil borings, piezometers or the observation of mottled soils.
