As part of submitting Improvement Plans, the developer shall prepare an Erosion and Sediment Control Plan according to the format and principles described in the Ohio Environmental Protection Agency’s general permit for storm water discharges associated with construction activity under the National Pollutant Discharge Elimination System (NPDES). Such plan shall be submitted to the Soil and Water Conservation District and the Village Road Commissioner as part of the Improvement Plan. Sediment control shall follow the standards and specifications in “Rainwater and Land Development” (Ohio Department of Natural Resources, USDA Natural Resources Conservation Service, Ohio Environmental Protection Agency).
When a proposed development area consists of one or more acres of earth disturbing activity, the owner of record shall prepare and submit an Erosion and Sediment Control Plan. When a proposed development area involves less than one acre, it is not necessary to submit an Erosion and Sediment Control Plan. However, the developer shall comply with the standards and specifications in “Rainwater and Land Development” (ODNR, NRCS, OEPA).
The following items provide a checklist for what shall be included in the Erosion and Sediment Control Plans:
(a) Site Description.
(1) A description of the nature and type of the construction activity.
(2) Total area of the site and area that is expected to undergo excavation, filling, or grading.
(3) Calculation of the runoff coefficients for both pre- and post-construction conditions.
(4) Describe the soil and quality of any discharge from the site.
(5) A schedule of construction operations.
(6) The name and/or location of the immediate receiving stream or surface water(s).
(7) Site map showing limits of earthmoving, existing contours, proposed contours, future drainage patterns, surface water locations (wetlands, streams) existing locations of buildings, proposed building locations and dimensions, erosion and sediment control practices, permanent storm water management practices.
(b) Vegetative Practices. A description of control practices designed to preserve existing vegetation where attainable and re-vegetate disturbed areas as soon as practicable after grading or construction shall be provided. Appropriate vegetative practices shall be initiated on all disturbed areas within seven days if the area(s) is to remain undisturbed for more than 45 days. In addition, permanent or temporary soil stabilization shall be applied to disturbed areas within seven days after final grade is reached on any portion of the site. Such vegetative practices may include temporary seeding, permanent seeding, sod, mulching, phasing and protection of trees, and vegetative buffer strips. When seasonal conditions prohibit the application of temporary or permanent seeding, non-vegetative soil stabilization practices such as mulching and matting shall be used.
(c) Structural Practices. A description of structural practices that shall store runoff allowing sediments to settle and/or divert flows from exposed soils or otherwise limit runoff from eroding exposed areas of the site shall be provided. Structural practices shall be used to control erosion and trap sediment from all sites remaining disturbed for more than 14 days. Such practices may include: sediment traps, sediments basins, silt fences, earth diversion dikes, check dams, storm drain inlet protection.
Sediment control structures shall be functional throughout earth disturbing activity. Sediment ponds and perimeter sediment barriers shall be implemented as the first step of grading and within seven days from the start of grubbing. They shall continue to function until the upslope development area is restabilized. Before any land disturbing activities begin, the Village Road Commissioner shall have approved the Erosion and Sediment Control Plan. The Village Road Commissioner will review the erosion control provisions of the plan and will review the storm water management aspect of the Plan.
The Village Road Commissioner will work to inspect the work, to ensure that the developer has installed the vegetative and structural practices as indicated on the approved plan. The developer and/or contractor shall take necessary procedures to prevent soil erosion and downwash of sediment onto adjoining properties or into existing drainage facilities. The Road Commissioner may require stoppage of work during construction if proper controls for soil erosion, siltation and sedimentation are not being provided by the developer or contractor. The Road Commissioner may take the necessary steps to provide corrective measures, and the cost of such services will be charged to the developer. This does not relieve the developer or contractor of downstream liabilities. No project will be released from bond for failure to comply with this regulation and without cleanup and repair of damages. Final inspection requires all drainage facilities to be free of depositions from erosion, siltation, and construction debris.
(d) Final Clean Up. Upon completion of the work and before acceptance, the developer and/or contractor shall clean all ground occupied or affected by the work. The entire area shall be left in a neat and presentable condition.
