such as subdivisions, the storm sewer protection shall be maintained until all up slope areas reach final stabilization, as determined by the City Engineer. (2) At the end of this period the site owner shall hydraulically clean the storm sewers to the satisfaction of the City Engineer. All sediments shall be removed from the system and shall not be flushed downstream. (k) Working Near, Or Crossing Streams and Wetlands: (1) Construction vehicles shall avoid water resources, wetlands, riparian areas, and their setbacks. If construction vehicles must cross these areas during con- struction, an approved temporary crossing shall be constructed. Streams, includ- ing intermittent streams with a defined bed and banks, shall be restabilized im- mediately after in- cliannel work is completed, interrupted, or stopped. Erodible materials will not be used in making stream crossings. (2) No soil, rock, debris, or any other material shall be dumped or placed into a water resource or into such proximity that it may slough, slip, or erode into a water resource unless such dumping or placing is authorized by the approving authority and, when applicable, the US Army Corps Of Engineers and Ohio EPA, for such purposes as, but not limited to, constructing bridges, culverts, and erosion or sediment control structures. (3) If construction activities disturb areas adjacent to streams, structural practic- es shall be designed and implemented on site to protect the adjacent streams from the impacts of sediment runoff. (1) Construction Entrance: (1) Measures shall be taken to prevent soil transport onto public roads, or sur- faces where runoff is not checked by sediment controls. (2) Stone with geotextile construction entrance(s) shall be implemented as re- quired by the City Engineer and the Ohio EPA. These will be planned and in- stalled according to the requirements in the most recent edition of the Ohio Rainwater and Land Development manual. (3) Where soil is transported onto a public road surface, the roads shall be cleaned thoroughly at the end of each day, or more frequently, in order to ensure public safety. Soil shall be removed from paved surfaces by shoveling or sweep- ing. Street washing shall be allowed only after shoveling or sweeping has re- moved most of the sediment and street sewer inlet protection is properly in- stalled unless end of sewer sediment ponds exist and are properly functioning. (4) Erodible material ramps in streets will not be used to enable equipment to cross curbs. Non - erosive materials (e.g. wood and stone) can be used. (in) Stabilization of Outfalls and Channels: Outfalls and constructed or modi- fied channels shall be designed and constructed to withstand the expected veloc- ity of flow from the planned post - development frequency storm without eroding. The planned post - construction velocity and flow shall include the entire contrib- uting watershed. (n) Establishment of Permanent Vegetation: A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Perma- nent vegetation shall not be considered established until ground cover is 17
