_, (3) Settling Facilities. Concentrated stormwater runoff from denuded areas shall pass through a sediment settling facility. The facility's storage capacity shall be seventy-five (75) cubic yards per acre of drainage area. A sediment basin shall be the required facility if the size of the denuded area contributing runoff exceeds five (5) acres. (4) Perimeter Controls. Sheet flow runoff from denuded areas shall be filtered or diverted to a settling facility. Perimeter controls such as sediment filters or diversions to settling facilities shall protect adjacent properties and waters of the City of North Olmsted and the State of Ohio from sediment transported by sheet flow. (5) Storm Sewer Inlet Protection. All storm sewer inlets which accept water runoff from the development area shall be protected so that sediment-laden water will not enter the storm sewer system without first being filtered or otherwise treated to remove sediment, unless the system drains to anon-site settling facility.

To the extent practicable, construction vehicles shall be kept out of streams. Where in-channel work is necessary, precautions shall betaken to stabilize the work area during construction to minimize erosion. (B) If a live (wet) stream must be crossed by construction vehicles regularly during construction, a temporary stream crossing shall provided. (7) Construction Access Routes.
