In compliance with § 159.20(A), one copy of the erosion and sediment control plan shall be submitted to the city and shall contain a narrative and a site plan. The narrative and a site plan. The following information is required.
(1) Project description - nature and purpose of land disturbing activity; acres of grading involved;
(2) Approximate acreage of overall site of each sublot and of rights-of-way;
(3) Existing site conditions - topography, vegetation and drainage;
(4) Adjacent areas - description of neighboring areas such as streams, lakes residential areas, roads, and the like, which might be affected by the land disturbance;
(5) Brief description of the soils on the site giving such information as soil name, erodibility, permeability, depth, texture and structure, and limitations for the proposed use. (Refer to the Soil Survey of Highland County, Ohio, released in March, 1973);
(6) Estimated impervious areas, stated in terms of square footage or acreage, whichever is appropriate;
(7) Critical areas - description of areas on the site which have potentially serious erosion problems;
(8) Erosion and sediment control measures, to minimize on-site erosion and to minimize off-site sedimentation;
(9) Provisions for management of stormwater, derived both on-site and from upper watershed areas shall be submitted to the city for review and approval;
(10) Details of temporary and permanent stabilization measures, including method of anchoring mulches;
(11) Maintenance schedule for inspection and repair of temporary erosion and sediment control structures;
(12) Sequence of construction describing implementation and maintenance of controls, temporary and permanent stabilization and earth-disturbance and construction. The sequence of construction shall, as a minimum, include a projected schedule and time frame for the following activities:
(a) Clearing and grubbing for those areas necessary for installation of perimeter controls;
(b) Construction of perimeter controls;
(c) Remaining clearing and grubbing;
(d) Road grading;
(e) Grading for the remainder of the site;
(f) Utility installation;
(g) Final grading, landscaping, and stabilization; and
(h) Removal of controls.
(13) Design computations and applicable assumptions for all temporary structural measures for erosion and sediment pollution control;
(14) Seeding mixtures and rates, lime and fertilizer application rates, and kind and quantity of mulching for both temporary and permanent vegetative control measures;
(15) Estimated cost of erosion and sediment control structures and features; and
(16) Name, address, and telephone number of the plan designer, the owner, and the person(s) responsible.
(B) Site plan.
(1) The site plan shall be drawn at a scale between 200 feet to the inch and 50 feet to the inch. Site plans shall be on one or more sheets 24 by 36 inches in size and shall be clearly and legibly drawn;
(2) Vicinity map at a scale of not less than 2,000 feet to the inch locating the site in relation to the surrounding area;
(3) Existing topography shown in two-foot contour intervals and showing drainage patterns and drainage areas showing direction of flow. Also show existing drainage patterns and facilities, road rights-of-way and easements. Also show topography in five-foot contour intervals on adjacent land within 200 feet of the site unless deemed not necessary by the city;
(4) Existing vegetation;
(5) Location of existing buildings, structures, utilities, water bodies, drainage facilities, vegetative cover, paved areas, road right-of-way, and other significant natural and human-made features in the development area, and of adjacent areas which might be affected by the land disturbance;
(6) Soil types and boundaries as shown on the Soil Survey of Highland County, Ohio, released in March, 1973;
(7) Title, scale, direction, legend, and date of all plan maps;
(8) Critical erosion areas;
(9) Existing and proposed drainage patterns, including the watershed lines direction of flow, and watershed acreage;
(10) Location and elevation of proposed erosion and sediment control structures;
(11) Profile of road cut and fill, with original ground profile proposed grade profile;
(12) Areas of excavation, grading and filling;
(13) Final contours;
(14) Limits of clearing and grading;
(15) Location of practices, including erosion and sediment control;
(16) Bottom width, side slopes and grade of ditches;
(17) Location of existing utilities;
(18) Location of existing easements;
(19) Detail drawings of any structural practices used that are not referenced in Water Management and Sediment Control for Urbanizing Areas; and
(20) Signed and sealed by professional engineer.
(C) Waiver. The city may waive specific requirements for plan detail or may require additional information to show that work will conform to the basic requirements of these regulations.
