16R.22.020 Sediment control.

   A.   Sediment caused by the grading project shall be retained on the site to the greatest extent feasible. The maximum permanent rate of sediment loss after completion of the project should not exceed the natural erosion rate which occurred prior to the grading project. If, in the opinion of the building official, excessive erosion occurs from the project, erosion and sediment control measures shall be immediately implemented to reduce erosion to allowable levels.

   B.   If required by the building official, sediment basins, sediment traps, or similar sediment control measures, temporary or permanent, shall be installed prior to clearing and grading operations. Upon completion of construction and stabilization of soils, all temporary erosion control facilities shall be removed from the site upon written approval of the building official.
