(A) The following principles are effective in minimizing erosion and sedimentation and shall be included where applicable in the control plan:
(1) Stripping of vegetation, regrading or other development shall be done in such a way that will minimize erosion. Whenever feasible, natural vegetation shall be retained, protected, and supplemented;
(2) Development plans shall preserve salient natural features, keep cut-fill operations to a minimum, and ensure conformity with topography so as to create the least erosion potential;
(3) The smallest practical area of land shall be exposed at any one time and the duration of exposure shall be kept to a practical minimum; the topsoil shall be revegetated;
(4) Disturbed soils shall be stabilized as quickly as practicable with temporary vegetation or mulching to protect exposed critical areas during development;
(5) The permanent final vegetation and structural erosion control and drainage measures shall be installed as soon as practical in the development;
(6) Provisions shall be made to effectively accommodate the increased runoff caused by changed soil and surface conditions during and after development. Where necessary, surface water runoff shall be structurally retarded;
(7) Sediment in the runoff water shall be trapped until the disturbed area is stabilized by the use of debris basins, sediment basins, silt traps, or similar measures.
(B) The following standards shall be followed in all soil erosion and sediment control plans:
(1) All lots, tracts, or parcels shall be graded to provide proper drainage away from buildings and dispose of it without ponding, and all land within a development shall be graded to drain and dispose of surface water without ponding, except where approved by the Planning Commission or its duly authorized representative;
(2) All drainage provisions shall be of such design to adequately handle the surface runoff and carry it to the nearest suitable outlet such as a curbed street, storm drain, or natural watercourse. Where drainage swales are used to divert surface waters away from buildings, they shall be sodded, planted, or paved as required and shall be of such slope, shape, and size as to conform with the requirement of the village;
(3) Concentration of surface water runoff shall only be permitted in swales or watercourses;
(4) The installation of the specified soil erosion and sediment control measures shall be accomplished in accordance with the standards and specifications contained in "Water Management and Sediment Control for Urbanizing Areas" on file with the Planning Commission or its duly authorized representative;
(5) During the construction phase, further consultive technical assistance will be furnished, if necessary, by the Planning Commission or its duly authorized representative, or by the Hamilton County Soil and Water Conservation District. The Planning Commission or its duly authorized representative, shall enforce compliance with the approved plans.
(C) As finally approved, the plan for soil erosion and sedimentation control required of the landowner or his agent under § 153.02, shall include but not be restricted to the following requirements:
(1) A vicinity sketch and boundary line survey of the site for which the permit is sought and on which the work is to be performed;
(2) Location of any buildings, structures, utilities, sewers, water and storm drains on the site where the work is to be performed;
(3) Location of any building or structure on land of adjacent property owners within 100 feet of the site;
(4) Elevations, contours, dimensions, location, and extent of all work proposed to be done, and the existing elevations or contours of the land in one foot intervals for slopes zero to six degrees, two-foot intervals for slopes six to 18 degrees, and five-foot intervals for slopes 18 degrees or more.
(5) A certification of the quantity of excavation and fill involved;
(6) Detailed plans of all drainage provisions, retaining walls, cribbing, vegetative practices, erosion and sediment control measures, location of approved fences around sediment basins, steep excavations, or ponding areas, and other protective devices to be constructed in connection with, or as a part of the proposed work, together with a map showing the drainage area of land tributary to the site, and estimated cubic foot per second runoff of the area served by any drain, computed in accordance with the current village storm drainage criteria;
(7) A timing schedule and sequence indicating the anticipated starting and completion dates of the development sequence: stripping or clearing, rough grading and construction, final grading and vegetative establishment, and maintenance, and the time of exposure of each area prior to the completion of effective erosion and sediment control measures;
(8) The estimated cost of the grading or filling and the cost of the required erosion controls.
