8-7-62: EROSION AND SEDIMENT CONTROL PLANS:
Erosion and sediment control plans prepared pursuant to this chapter shall comply with all of the following:
   (A)   The erosion and sediment control plan need not be a separate sheet if all facilities and measures can be shown on the grading sheets without obscuring the clarity of either the grading plan or the erosion and sediment control plan.
   (B)   An erosion and sediment control plan shall be required whenever:
      1.   The graded portion of the site includes more than ten thousand (10,000) square feet of area having a slope greater than ten percent (10%).
      2.   There is a significant risk that more than two thousand five hundred (2,500) square feet will be unprotected or inadequately protected from erosion during any portion of the rainy season.
      3.   Grading will occur within twenty feet (20') of any watercourse or within the 50-year floodplain.
      4.   The city engineer determines that the grading will or may pose a significant erosion or sediment discharge hazard for any reason.
   (C)   The applicant shall submit, with his erosion and sediment control plans, a detailed cost estimate covering this work.
   (D)   Erosion and sediment control plans shall include an effective revegetation program to stabilize all disturbed areas which will not be otherwise protected. All such areas where grading has been completed between May 1 and October 15 shall be planted by November 1, or at the recommendation of the soil conservation service. Graded areas completed at other times of the year shall be planted within fifteen (15) days. If revegetation is unfeasible or cannot be expected to stabilize an erodible area with assurance during any part of the rainy season and the unstable area exceeds two thousand five hundred (2,500) square feet, additional erosion and sediment control measures or irrigation of planted slopes may be required as appropriate to prevent increased sediment discharge.
   (E)   Erosion and sediment control plans shall be designed to prevent increased discharge of sediment at all stages of grading and development from initial disturbance of the ground to project completion. Every feasible effort shall be made to ensure that site stabilization is permanent. Plans shall indicate the implementation period and the stage of construction where applicable.
   (F)   Erosion and sediment control plans shall comply with the recommendations of any civil engineer, geotechnical engineer, engineering geologist, or landscape architect involved in preparation of the grading plans.
   (G)   The structural and hydraulic adequacy of all storm water containment or conveyance facilities shown on the erosion and sediment control plans shall be verified by a civil engineer, and he shall so attest on the plans. Sufficient calculations and supporting material to demonstrate such adequacy shall accompany the plans when submitted.
   (H)   Erosion and sediment control plans shall be designed to meet anticipated field conditions.
   (I)   Erosion and sediment control plans shall provide for inspection and repair of all erosion and sediment control facilities at the close of each working day during the rainy season and for specific sediment cleanout and vegetation maintenance criteria.
   (J)   Erosion and sediment control plans shall comply with any and all standards and specifications adopted herein for the control of erosion and sedimentation on grading sites. These standards and specifications shall be in general compliance with the "Erosion And Sediment Control Guidelines For Developing Areas Of The Sierras", published by High Sierra Resource Conservation and Development Council.
