This section is intended and adopted for the purpose of regulating earth disturbing activities to control sediment pollution and to protect the storm drainage system and water resources from sedimentation, both of which are caused by accelerated soil erosion during development or construction.
(a) General Requirements. No person owning or responsible for a development or any earth moving activity, shall cause or allow earth disturbing activities except in compliance with the standards and criteria of subsection (b) hereof and the applicable items below.
(1) When a proposed development area involves less than five acres, all earth disturbing activities shall be subject to surveillance and site investigations by the City Engineer to determine compliance with the standards and regulations.
(2) When a proposed development area involves more than five acres, the responsible person shall develop and obtain approval of a sediment control plan prior to any earth disturbing activity. Such plan shall include specific requirements of the design manual adopted by the City, and be filed with the preliminary plat.
(3) A statement of policy for sediment control (a continuing narrative plan) in conjunction with standard operations, such as the installation of transmission lines by utility companies or road and highway construction or maintenance and stream channel improvement or maintenance, by public entities or agencies, may be approved by the Planning Commission in lieu of a specific plan each development.
(4) In all construction or earth disturbing work contracted to be done by the City, the specifications shall include the criteria listed in subsection (b) below.
(b) Standards and Criteria. Meeting the following standards and criteria does not relieve any person from liability for sediment damage to another's property. To control sediment pollution, the developer shall use methods as set forth in the Ohio Department of Transportation Construction and Materials Specifications and Location and Design Manual, or the latest U. S. Soil Conservation Service Handbook, Water Management and Sediment Control for Urbanizing Areas, or any other methods providing they are acceptable to the City Engineer.
(c) Plan Content. The preliminary plan of a proposed development area shall contain the following information to set forth how the standards and criteria by this section shall be met:
(1) Identification and location of off-site areas susceptible to sediment deposits or to erosion caused by accelerated runoff.
(2) Identification and location of off-site areas affecting potential accelerated runoff and erosion control.
(3) Existing topography of the development area and adjacent land within approximately 100 feet of the boundaries. A topographic map should contain a two foot contour interval to portray the conformation and drainage pattern of the area.
(4) The location of existing buildings, structures, utilities, water bodies, drainage facilities, vegetative cover, paved areas, (streets, roads, driveways, sidewalks, etc.), and other significant natural or man-made features on the development area and adjacent land within approximately 100 feet of the boundaries.
(5) A general description of the predominant soil types, their location and their limitations for the proposed use.
(6) Proposed use of the development area including present development and ultimate utilization with detail on soil cover both vegetative and impervious.
(7) All proposed earth disturbances including:
A. Areas of excavation, grading and filling.
B. The finished slope, stated in feet horizontal to feet vertical, of cut and fill slopes.
C. Kinds of utilities and proposed areas of installation.
D. Proposed paved and covered areas in square feet or to scale on a plan map.
E. Makeup of surface soil as developed (upper six inches) on areas not covered by buildings, structures or pavement. Description shall be in such terms as original surface, soil, subsoil, sandy, heavy clay, stony, etc.
F. Proposed kind of cover on areas not covered by buildings, structures or pavement. Description shall be in such terms as lawn, turfgrass, shrubbery, trees, forest cover, rip-rap, mulch, etc.
(8) Provisions for temporary and permanent erosion control.
(9) Provisions for the management of storm water, including the control accelerated runoff, to a stable receiving outlet.
(10) Provisions for maintenance of control facilities including easements to insure short as well as long term erosion and sediment pollution control and storm water management.
(11) Proposed construction sequence and time schedule for all earth disturbing activities and installation of provisions for erosion and sediment pollution and storm water management.
(12) Design computations and applicable assumptions for all structural measures for erosion and sediment pollution control and water management. Volume and velocity of flow shall be given for all surface water conveyance measures and pipe outfalls.
(13) Seeding mixtures and rates, lime and fertilizer application rates, and kind and quantity of mulching for both temporary and permanent vegetative control measures.
(14) Title, scale, direction, legend and date of all plan maps.
(15) Name and address of the person(s) preparing the plan, the owner, and the person responsible for the development area.
(16) Certification that all earth disturbance, construction and development shall be done pursuant to the plan.
