(a) In order to control pollution of water resources and wetlands, the applicant shall submit a SWP3 in accordance with the requirements of this regulation. The SWP3 must comply at a minimum to the most recent Ohio EPA NPDES Permit. For specific requirements of a SWP3 the designer shall refer to the NPDES Ohio general construction permit and the Summit SWCD SWP3 Check List. The SWP3 must address erosion and sediment control during construction as well as post construction water quality practices. Post construction practices must meet the requirements of the NPDES Ohio general construction permit and the Summit County storm water management technical guidelines.
(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
(d) Trapping Efficiency: All sediment basins and traps must maintain a minimum seventy-five percent (75%) trapping efficiency throughout the construction period as determined by engineering calculations contained within the Summit County Water Quality and Trapping Efficiency Program. The approved program to determine trapping efficiency is available through the Summit Soil and Water Conservation District
(e) Soils engineering report: The City 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 upon adequate and necessary test borings, and shall contain all the information listed below. Recommendations included in the report and reviewed by the City Engineer shall be incorporated in the grading plans and/or other specifications for site development.
(1) Data regarding the nature, distribution, strength, stability, and erodibility of existing soils.
(2) If applicable, data regarding the nature, distribution, strength, stability, and erodibility of the soil to be placed on the site.
(3) Conclusions and recommendations for grading procedures.
(4) Conclusions and recommended designs for interim soil stabilization devices and measures, and for permanent soil stabilization after construction is completed.
(5) Design criteria for corrective measures when necessary.
(6) Opinions and recommendations concerning the stability of the site.
