EXHIBIT B: NEW CHAPTER 927 <br />area to silt fence for a particular slope range is shown in Table 3 below. Placing <br />silt fence in a parallel series does not extend the size of the permissible drainage <br />area. <br />Table 3: Maximum Drainage Area to Silt Fence Based on Slope <br />Maximum Drainage Area (acres) to <br />100 linear feet of silt fence <br />Range of slope for a drainage area (%) <br />0.5 <br /><2% <br />0.25 <br />> 2% but < 20% <br />0.125 <br />> 20% but < 50% <br />(4) Alternative perimeter controls for sheet flow discharges may be considered by the <br />City of North Olmsted, but their use shall not exceed the limitations indicated in <br />Table 3 above. Detail drawings and plan notes shall specify the diameter of filter <br />socks, compost berms and other such alternative perimeter controls if used instead <br />of silt fence. <br />(5) Stormwater diversion practices shall be used to keep runoff away from disturbed <br />areas and steep slopes. Such devices, which include swales, dikes or berms, may <br />receive storm water runoff from areas up to 10 acres. <br />(6) Inlet protection. Erosion and sediment control practices, such as boxed inlet <br />protection, shall be installed to minimize sediment -laden water entering active <br />storm drain systems. All inlets receiving runoff from drainage areas of one or <br />more acres will require a sediment settling pond. Straw or hay bales and filter <br />socks around catch basins are not acceptable forms of inlet protection. <br />(7) Off-site tracking of sediment and dust control. Best management practices must <br />be implemented to ensure sediment is not tracked off-site and that dust is <br />controlled. These best management practices must include, but are not limited to, <br />the following: <br />A. Construction entrances shall be built and shall serve as the only <br />permitted points of ingress and egress to the development area. <br />These entrances shall be built of a stabilized pad of aggregate stone <br />or recycled concrete or cement sized greater than 2" in diameter, <br />placed over a geotextile fabric, and constructed in conformance <br />with specifications in the most recent edition of Rainwater and <br />Land Development. <br />B. Streets and catch basins adjacent to construction entrances shall be <br />kept free of sediment tracked off site. Streets directly adjacent to <br />construction entrances and receiving traffic from the development <br />
