H. Any other storm water related items required by the City Engineer; <br />I. A prohibition on alteration of any BMPs without prior written approval from <br />the City Engineer; and <br />J. An Inspection and Maintenance Agreement, as defined in Section 1339.11 of <br />this chapter. <br />1339.09 CONSTRUCTION MINIMUM STANDARDS. <br />In order to control sediment pollution of water resources, the owner or person <br />responsible for the development area shall use conservation planning and prac- <br />tices to maintain the level of conservation established in the following standards. <br />The pem»ttee must adhere to all requirements of the EPA Construction General <br />Permit. In addition, the following items are general guidelines and shall not lim- <br />it the right of the City Engineer to impose at any time additional, more stringent <br />requirements, nor shall the guidelines limit the right of the City Engineer to <br />waive, in writing, individual requirements. <br />(a) The plan shall include measures that control the flow of runoff from dis- <br />turbed areas so as to prevent soil erosion from occurring. <br />(b) Structural Practices shall be used to control erosion and trap sediment from <br />areas remaining disturbed for more than 21 days. <br />(c) Sediment Barriers: Sheet flow runoff from denuded areas shall be intercept- <br />ed by Silt Fence or Diversions to protect adjacent properties and water resources <br />from sediment. Where intended to provide sediment control, Silt Fence shall be <br />placed on a level contour. The relationship between the maximum drainage are- <br />as to Silt Fence for a particular slope is shown in the table below: <br />Table 1: Silt Fence Applicability <br />Maximum drainage area <br />Range of slope for a par - <br />(in acres) to 100 linear feet <br />ticular drainage area (in <br />of silt Fence <br />percent) <br />0.5 <br /><2% <br />0.25 <br />> 2% but < <br />20% <br />0.125 <br />>20% but < <br />50% <br />This does not preclude the use of other sediment barriers designed to control <br />sheet flow runoff. The total runoff flow treated by a sediment barrier shall not <br />exceed the design capacity for that sediment barrier. Straw Bale Barriers are not <br />acceptable. <br />(d) Storm Water Diversion Practices: Storm water diversion practices shall be <br />used to keep runoff away from disturbed areas and steep slopes where practica- <br />ble. Such practices, which include Swales, Dikes or Berms, Pipe Slope Drains <br />14 <br />
