(a) Plan Requirements.
(1) When required by this regulation, a soil erosion and sediment control plan shall be required for the land disturbance activities outlined in Section 1399.03. Furthermore, in accordance with the appropriate requirements of Section 1399.03, the plan shall be prepared, submitted to the City, and approved by the City, prior to any earth-or land-disturbance. The person proposing land-disturbing activities shall submit the plan, and supporting information, as outlined herein, to the following office:
Administrator
City of Groveport
655 Blacklick Street
Groveport, OH 43125
(2) The erosion and sediment control plan shall contain sufficient information, drawings, and notes to describe how soil erosion and off-site sedimentation will be minimized. The erosion and sediment control plan is to be submitted as part of the site improvement plan(s). The City shall review the plan to determine compliance with this regulation and the Standards and Specifications prior to approval. The plan shall serve as a basis for all subsequent grading and stabilization.
(b) Erosion and Sediment Control Plan Content. Any person seeking approval of a land disturbance proposal shall, on a map rendered from a base derived from the site improvement plan(s) or site grading plan, at a scale not to exceed 1"=100', provide the following information:
(1) Location of the land disturbance area and off-site borrow or spoil areas and its general surroundings including but not limited to:
A. Vicinity map indicating north arrow, scale, and other information necessary to easily locate the site;
B. Off-site areas susceptible to sediment deposits or to erosion caused by accelerated runoff from the land disturbance area, such as ponds and small streams;
C. Off-site areas affecting potential accelerated runoff and erosion control.
D. Name and location of the immediate receiving stream or surface water(s) and the first subsequent named receiving water(s). Also shall be described, the areal extent and description of wetlands or other special aquatic sites at or near the project site that will be disturbed or that will receive discharges from disturbed areas of the project site.
(2) Existing topography of the land disturbance area and adjacent land within fifty feet of the boundaries. A topographic map should contain an appropriate contour interval to clearly portray the conformation and drainage pattern of the area;
(3) 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 land disturbance area and adjacent land within fifty feet of the boundaries.
(4) A general description of the predominant soil types, their location and their limitations for the proposed use;
(5) Proposed use of the land disturbance area including present development and ultimate utilization with detail on final soil cover, both vegetative and impervious;
(6) All proposed earth disturbance including:
A. Total area of the site and off-site borrow or spoil areas including areas of site disturbance, excavation, grading, and filling.
B. Total off-site contributory area.
C. The proposed final elevations and slopes.
D. Kinds of utilities and proposed areas of installation.
E. Proposed paved and covered areas in square feet.
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;
(7) Provisions for temporary and permanent erosion and sedimentation control, per the standards of Section 1399.05. Provisions should include the number, types, dimensions, and locations of all runoff, erosion or sediment control devices to be utilized either temporarily or permanently on the area of land disturbance.
(8) Provisions for management of stormwater, per the requirements of this chapter and the City's Stormwater Management Policy (Chapter 935). Provisions should be made for both on-site and off-site tributary areas, including control of accelerated on-site runoff to a stable receiving outlet, the site conditions around points of all surface water discharge from the site, and velocities of the 10-year flow at outfalls;
(9) For subdivided developments where the plan does not call for a centralized sediment control (such as sediment basin or trap) capable of controlling multiple individual lots, a detail drawing of a typical individual lot showing standard individual lot erosion and sediment control practices;
(10) Description of measures that will be undertaken to prevent pollution of existing streams during construction activities and after construction is complete.
A. Description of mitigation measures to repair damage to the stream channels if the stream channel must be disturbed.
B. Justification for earth disturbance within the stream channel.
(11) Provisions for maintenance of control facilities including easements to ensure short term erosion and sediment pollution control;
(12) Proposed construction sequence describing the relationship between the implementation and maintenance of controls, including permanent and temporary stabilization and the various stages or phases of earth disturbance and construction. The sequence of construction shall, as a minimum, include a 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 and whether storm drains will be used, protected or abandoned after construction;
G. Final grading, landscaping or stabilization; and;
H. Removal of controls.
(13) Seeding mixtures and rates, lime and fertilizer application rates, and kind and quantity of mulching for both temporary and permanent vegetative control measures. Details on proposed methods and schedules of providing temporary and permanent stabilization, pertaining to seeding and/or mulching shall be included;
(14) Map reference data including title, scale, direction, legend, and date on all plan maps; additionally, the plan, as part of the overall stormwater drainage plan, shall provide space for signatures of City of Groveport officials;
(15) Statement identifying the name, address, and telephone number of the person(s) preparing the plan, the owner of the property where the grading is proposed and the developer and/or person responsible for the development area;
(16) A statement indicating that the owner will notify the City forty-eight (48) hours before commencing any land disturbing activity. At the time this notice is given, the owner shall identify the site manager.
(17) Appearing on the Erosion and Sediment Control Plan, as part of the overall Stormwater Drainage Plan, shall be a certification (signature and seal) by a Professional Engineer, registered in the State of Ohio, that the plan has been prepared in accordance with the requirements of this chapter, and in accordance with good engineering practices and principles.
(c) The Administrator may waive specific requirements for plan detail or may require additional information to show that work will conform to basic requirements of this chapter.
(d) Any person seeking approval of an Erosion and Sediment Control Plan shall submit design computations and applicable assumptions for all structural measures for erosion and sediment control. Volume and velocity of flow shall be provided for all surface water conveyance. This information shall also be provided for surface water outlets.
(e) Any person seeking approval of an Erosion and Sediment Control Plan shall submit to the City of Groveport Administrator a copy of the "Notice of Intent" that seeks coverage under the most current effective version of the Ohio EPA Construction General Permit (as of the application date of the proposed Plan) that has been or will be filed with the Ohio Environmental Protection Agency.
