the topsoil; covering or stabilizing all soil stockpiles; using wind erosion control; intercepting runoff above disturbed slopes and conveying it to a safe place to deposit and receive such waters; constructing benches, terraces, or ditches at regular intervals to intercept runoff on long or steep disturbed or man-made slopes; providing linings or other method to prevent erosion of storm water conveyance channels; using check dams where needed to slow flow velocities; and using seeding and fertilizing, mulching, sodding, matting,. blankets, bonded fiber matrices, or other effective soil erosion control technique. (e) Sediment control. In addition to the erosion control measures above, provide practices to capture sediment that is transported in runoff to prevent the sediment from leaving the site erosion control measures in accordance with erosion and sedimentation control standards and guidelines established by the department of public works. Filtration and detention (gravitational settling) are the main processes used to remove sediment from construction site runoff. Sediment control measures include sediment basins; sediment traps; filter fabric silt fences; straw bale, sand bag, or gravel bag barriers; inlet protection; stabilized construction entrances, vehicle wheel wash facilities and other measure to minimize off-site tracking of sediment by construction vehicles; and vegetated filter strips. (f) Material and waste management. Measures to ensure the proper storage of potential pollutants and prevent the discharge of pollutants associated with construction materials and wastes shall be implemented. (g) Timing of control measure implementation. Timing of control measure implementation shall be in accordance with the approved erosion control plan if such plan is required. At a minimum, when there are no approved erosion control plans, disturbed areas of a construction site that will not be redisturbed for 21 days or more will be stabilized (grassed, graveled or other measures) by no later than the 14th day after last disturbance. Section 10-4. Hazardous conditions. (a) Whenever the director of public works determines that any existing excavation, fill, grubbing, stockpiling or grubbed vegetation has become a hazard tb property, or adversely affects the safety, use, or stability of a public way or drainage channel, the owner of the property upon which the excavation, fill, grubbing, stockpiling or grubbed vegetation is located, or other person or agent in control of said property shall repair or eliminate the hazard and be in conformance with the requirements of this chapter. (b) The director of public works or the director's authorized representatives are hereby authorized to enter any property to determine or to enforce the provisions of this chapter. Section 10-5. Agricultural Operations. (a) Agricultural operations, including ranching incidental to or in conjunction with crop or livestock production, that conform with soil conservation practices and are in accordance with an actively pursued comprehensive conservation plan, prepared by an engineer or conservationist, shall be exempt from the provisions of this chapter provided: (1) Such operations do not alter the general and localized drainage patterns with respect to abutting properties based on best available information. (2) The conservation plan for the affected properties have been reviewed and approved by the applicable soil and water conservation district directors. -4-
