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; using seeding and fertilizing, mulching, sodding, matting, blankets, bonded fiber matrices, or other effective soil erosion control technique; and providing vehicle wheel wash facilities for vehicles before they leave the site. (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. 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, 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 toxic material 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 to 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 or stockpiling is located, or other person or agent in control of said property, upon receipt of notice in writing from the director of public works shall within the period specified therein 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 a registered 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. (3) The conservation plan, including any approved modifications, is reviewed and reapproved by the applicable soil and water conservation district directors not less than once every five years. me
