In order to control storm water damage and sediment pollution of water resources, wetlands, riparian areas, other natural areas, and public and private lands, the owner of each development area shall be responsible for developing a comprehensive Construction Site Conservation Plan. This plan will address storm water management (volume and peak rate of runoff), soil erosion, sediment and other wastes control. This plan must contain a description of controls appropriate for each construction operation covered by these regulations, and the operator must implement the planned controls in a timely manner. The plan and BMPs used to satisfy the conditions of these regulations shall meet the standards and specifications in the current edition of the Ohio Rain Water and Land Development manual. The plan must make use of the practices that preserve the existing natural condition to the Maximum Extent Practicable. The plan shall identify the subcontractors engaged in activities that could impact storm water runoff. The Construction Site Conservation Plan shall contain signatures from all of the identified subcontractors indicating that they have been informed and understand their roles and responsibilities in complying with the Construction Site Conservation Plan.
(a) Redevelopment Exemption: Owners of development sites that were created by demolishing an older existing structure can request, in writing, that the Village Administrator exempt them from the storm water issues if the total soil surface area being made impermeable is the same or less than the total soil surface area that was impermeable due to the structure(s) being torn down and removed.
(b) Riparian and Wetland Setbacks: All riparian and wetland setback areas will be identified in the plan and in the field before construction starts.
(c) Soil Erosion and Sediment Issues: A sketch of the entire development site must be submitted that identifies the location of:
(1) All existing and planned impervious areas, storm water inlets, drainage swales, wetlands, streams, conservation easements and other natural features to be saved and protected on the property.
(2) All existing and planned temporary and permanent conservation practices for the site. Residential lots shall include at a minimum the following:
A. Soil erosion and sediment control BMPs, and;
B. Construction Entrance, and;
C. Temporary Grass Seeding with 2 tons per acre of straw mulch, and;
D. Storm Drain Inlet Protection around every storm yard inlet on the site or accepting drainage from the site, and;
E. Silt Fence protection for any stream located on or close to the site and lacking an adequate vegetative buffer, and;
F. Silt Fence to prevent sediment discharge into street storm sewer inlets where no centralized sediment control exists for the drainage area that includes the lot, and;
G. Construction fence to protect any conservation easements, riparian setbacks and wetland setbacks from encroachment by construction activities.
(d) The schedule for the use of Temporary Seeding developed according to the Temporary Seeding Table contained in the Minimum Standards Section of this chapter must be included. The location of construction material stockpile areas, if such have been approved by the Community Engineer, with a description of the Soil Erosion and Sediment Controls to be maintained on the stockpile area prior to, during, and after the area is used for stockpiling.
