Setbacks. Cut and fill slopes shall be set back from drainage courses a minimum of 25 feet from the top of bank. Additional setbacks may be required by other regulatory agencies such as Oregon Department of State Lands, Oregon Department of Land Conservation and Development, and Federal Emergency Management Agency. Cut and fill slopes shall be set back from site boundaries as described below: ▪ Top of Cut Slope. The top of cut slopes shall not be made nearer to a site boundary line than one fifth of the vertical height of cut with a minimum of 2 feet and a maximum of 10 feet. The setback may need to be increased for any required interceptor drains. ▪ Toe of Fill Slope. The toe of fill slope shall be made not nearer to the site boundary line than one fifth the height of the slope with a minimum of 2 feet and a maximum of 20 feet. Where a fill slope is to be located near the site boundary and the adjacent off-site property is developed, special precautions shall be incorporated in the work as the City deems necessary to protect the adjoining property from damage as a result of such grading. These precautions may include, but are not limited to: o Additional setbacks. o Provision for retaining or slough walls. o Mechanical or chemical treatment of the fill slope surface to minimize erosion. o Provisions for the control of surface waters
