<br />Ordinance No. 2003-86 <br />shall use conservation planning and practices to maintain the level of conservation <br />established by the minimum standards. <br />(b) The minimum standards are general criteria and shall not limit the right of <br />the City Engineer to impose additional, more stringent requirements whenever a plan <br />which meets the requirements of this Chapter is not adequate due to special <br />circumstances. <br />(c) Erosion and sediment control practices used to satisfy the standards shall <br />meet the specifications in the current edition of Water Management and Sediment <br />Control for Urbanizing Areas (Soil Conservation Service, Ohio). <br />The minimum standards axe listed below: <br />(1) Timing of sediment trapping practices. Sediment control practices <br />shall be functional throughout earth disturbing activity. <br />Settling facilities, perimeter controls, and other practices intended <br />to trap sediment shall be implemented as the first step of grading <br />and within seven days from the start of grubbing. They shall <br />continue to function until the upslope development area is <br />restabilized. <br />(2) Stabilization of denuded areas. Denuded areas shall have soil <br />stabilization applied within seven days if they axe to remain <br />dormant for more than thirty (30) days. <br />Permanent or temporary soil stabilization shall be applied to <br />denuded areas within seven days after final grade is reached on any <br />portion of the site, and shall also be applied within seven days to <br />denuded areas which may not be at final grade, but will remain <br />dormant (undisturbed) for longer than thirty (30) days. Permanent <br />or temporary soil stabilization shall be applied to denuded areas <br />within fifty (50) feet of a stream within two (2) days of reaching <br />final grade or wrthin two (2) days of the most recent disturbance if <br />the area will remain idle for seven (7) days or more. <br />(3) Settling facilities. Concentrated stormwater runoff from denuded <br />areas shall pass through a sediment settling facility. <br />The facility's storage capacity shall be seventy-five (75) cubic <br />yards per acre of drainage area. A sediment basin shall be the <br />required facility if the size of the denuded area contributing runoff <br />exceeds five (5) acres. <br />(4) Perimeter Controls. Sheet flow runoff from denuded areas shall be <br />filtered or diverted to a settling facility. <br />Perimeter controls such as sediment filters or diversions to settling <br />facilities shall protect adjacent properties and waters of the City of <br />North Olmsted and the State of Ohio from sediment transported by <br />sheet flow. <br />(5) Storm sewer inlet protection. All storm sewer inlets which accept <br />water runoff from the development area shall be protected so that <br />sediment-laden water will not enter the storm sewer system <br />without first being filtered or otherwise treated to remove <br />sediment, unless the system drains to an on-site settling facility. <br />The site owner shall hydraulically clean the storm sewers after <br />denuded areas have been stabilized to the satisfaction of the City <br />Engineer. All sediments shall be removed from the system and <br />shall be properly disposed of and shall not be flushed downstream. <br />(6) Working in or crossing streams.
