1145.03  URBAN SOIL SEDIMENT POLLUTION CONTROL.
   No person shall cause or allow earth-disturbing activities on a development/ construction area except in compliance with the standards and criteria set out below.
   (a)    To control pollution of public waters by soil sediment from accelerated sheet and rill erosion on a development area, the responsible person shall:
(1)    Construct and maintain sediment basins sized in accordance with the U.S. Soil Conservation Service handbook entitled, "Water Management and Sediment Control for Urbanizing Areas"; or
(2)    Utilize other measures identified within the handbook or other acceptable measures approved by the City Manager.
   (b)    To control pollution of public waters by soil sediment from accelerated erosion in drainageways and grassed waterways and in streams and ditches disturbed or modified in conjunction with the development/construction process, the responsible person shall:
(1)    Design, construct, and maintain concentrated water flow channels such that the velocity of flow does not exceed the permissible velocities provided by the City Manager; or
(2)    Utilize other measures identified within the handbook or other acceptable measures approved by the City Manager.
   (c)    To control sediment pollution of public waters caused by sloughing, landsliding, or dumping of earth material, or placing of earth material into such proximity that it may readily slough, slide, or erode into public waters by natural forces, no person shall:
(1)    Dump or place earth material into public waters or into such proximity that it may readily slough, slide or erode into public waters unless such dumping or placing is authorized by the City Manager for such purposes as, but not limited to, constructing bridges, culverts, erosion control structures and other instream or channel bank improvement works; or
(2)    Grade, excavate, fill or impose a load upon any soil or slope known to be prone to slipping or landsliding, thereby causing it to become unstable, unless qualified engineering assistance has been employed to explore the stability problems and make recommendations to correct, eliminate or adequately address the problem.
