8-7-60: EROSION AND SEDIMENT CONTROL:
The following shall apply to the control of erosion and sediment from grading operations:
   (A)   Grading plans shall be designed with long term erosion and sediment control as a primary consideration.
   (B)   Grading operations during the rainy season shall provide erosion and sediment control measures except upon a clear demonstration to the satisfaction of the city engineer that at no stage of the work will there be any substantial risk of increased sediment discharge from the site.
   (C)   Should grading be permitted during the rainy season, the smallest practicable area of erodible land shall be exposed at any one time during grading operations and the time of exposure shall be minimized.
   (D)   Wherever possible, natural features, including vegetation, trees, terrain, watercourses, wetlands and similar resources shall be preserved. Limits of grading shall be clearly defined and marked to prevent damage by construction equipment. Wetlands and trees shall be protected from construction activity as described in the design and improvement standards manual.
   (E)   Permanent drought resistant vegetation and structures for erosion and sediment control shall be installed as soon as possible.
   (F)   Adequate provision shall be made for long term maintenance of permanent erosion and sediment control structures and vegetation.
   (G)   No topsoil shall be removed from the site unless otherwise directed or approved by the city engineer. Topsoil overburden shall be stockpiled and redistributed within the graded area after rough grading to provide a suitable base for seeding and planting. Runoff from the stockpiled area shall be controlled to prevent erosion and resultant sedimentation of receiving water.
   (H)   Runoff shall not be discharged from the site in quantities or at velocities substantially above those which occurred before grading except into drainage facilities of which the design has been specifically approved by the city engineer.
   (I)   Permittee shall take reasonable precautions to ensure that vehicles do not track or spill earth materials into public streets and shall immediately remove such materials if this occurs. (Ord. 1523, 4-11-1995)
