(a) In order to control sediment pollution of water resources and wetlands, the applicant shall submit a SWP3 in accordance with the requirements of this regulation.
(b) The SWP3 shall be certified by a professional engineer, a registered surveyor, certified professional erosion and sediment control specialist, or a registered landscape architect.
(c) The SWP3 shall incorporate measures as recommended by the most current edition of Rainwater and Land Development as published by the Ohio Department of Natural Resources and shall include the following information:
(1) Site description: The SWP3 shall provide:
A. A description of the nature and type of the construction activity (e.g. residential, shopping mall, highway, etc.).
B. Total area of the site and the area of the site that is expected to be disturbed (i.e., grubbing, clearing, excavation, filling or grading, including off-site borrow areas).
C. An estimate of the impervious area and percent of imperviousness created by the soil-disturbing activity.
D. Existing data describing the soil and, if available, the quality of any known pollutant discharge from the site such as that which may result from previous contamination caused by prior land uses.
E. A description of prior land uses at the site.
F. An implementation schedule which describes the sequence of major soil-disturbing operations (i.e., grubbing, excavating, grading, utilities and infrastructure installation) and the implementation of erosion and sediment controls to be employed during each operation of the sequence.
G. The location and name of the immediate receiving stream or surface water(s) and the first subsequent receiving water(s).
H. The aerial (plan view) extent and description of wetlands or other special aquatic sites at or near the site which will be disturbed or which will receive discharges from disturbed areas of the project.
I. For subdivided developments where the SWP3 does not call for a centralized sediment control capable of controlling multiple individual lots, a detail drawing of a typical individual lot showing standard individual lot erosion and sediment control practices.
J. Location and description of any storm water discharges associated with dedicated asphalt and dedicated concrete plants associated with the development area and the best management practices to address pollutants in these storm water discharges.
K. Site map showing:
1. Limits of soil-disturbing activity of the site, including off site spoil and borrow areas.
2. Soils types should be depicted for all areas of the site, including locations of unstable or highly erodible soils.
3. Existing and proposed one foot contours. This must include a delineation of drainage watersheds expected during and after major grading activities as well as the size of each drainage watershed in acres.
4. Surface water locations including springs, wetlands, streams, lakes, water wells, etc., on or within 200 feet of the site, including the boundaries of wetlands or stream channels and first subsequent named receiving water/waters the applicant intends to fill or relocate for which the applicant is seeking approval from the Army Corps of Engineers and/or Ohio EPA.
5. Existing and planned locations of buildings, roads, parking facilities, and utilities.
6. The location of all erosion and sediment control practices, including the location of areas likely to require temporary stabilization during the course of site development.
7. Sediment ponds, including their sediment settling volume and contributing drainage area.
8. Areas designated for the storage or disposal of solid, sanitary and toxic wastes, including dumpster areas, areas designated for cement truck washout, and vehicle fueling.
9. The location of designated stoned construction entrances where the vehicles will ingress and egress the construction site.
10. The location of any in-stream activities including stream crossings.
(2) A soil engineering report: The Village Engineer may require the SWP3 to include a Soils Engineering Report based upon his/her determination that the conditions of the soils are unknown or unclear to the extent that additional information is required to protect against erosion or other hazards . This report shall be based on adequate and necessary test borings, and shall contain all the information listed below. Recommendations included in the report and approved by the Village Engineer shall be incorporated in the grading plans and/or other specifications for site development.
A. Data regarding the nature, distribution, strength, and erodibility of existing soils.
B. If applicable, data regarding the nature, distribution, strength, and erodibility of the soil to be placed on the site.
C. Conclusions and recommendations for grading procedures.
D. Conclusions and recommended designs for interim soil stabilization devices and measures, and for permanent soil stabilization after construction is completed.
E. Design criteria for corrective measures when necessary.
F. Opinions and recommendations covering the stability of the site.
