or tree wells; stockpiling topsoil, covering the stockpile to prevent dust, and reapplying
<br />the topsoil; covering or stabilizing all soil stockpiles; using wind erosion control;
<br />intercepting runoff above disturbed slopes and conveying it to a safe place to deposit and
<br />receive such waters; constructing benches, terraces, or ditches at regular intervals to
<br />intercept runoff on long or steep disturbed or man-made slopes; providing linings or other
<br />method to prevent erosion of storm water conveyance channels; using check dams where
<br />needed to slow flow velocities; and using seeding and fertilizing, mulching, sodding,
<br />,matting, blankets, bonded fiber matrices, or other effective soil erosion control technique

<br />(e) Sediment control. In addition to the erosion control measures above, provide practices to
<br />capture sediment that is transported in runoff to prevent the sediment from leaving the
<br />site in accordance with erosion and sedimentation control standards and euidelines
<br />established by the department of public works. Filtration and detention (gravitational
<br />settling) are the main processes used to remove sediment from construction site runoff.
<br />Sediment control measures include sediment basins; sediment traps; filter fabric silt
<br />fences; straw bale, sand bag, or gravel bag barriers; inlet protection; stabilized
<br />construction entrances, vehicle wheel wash facilities and other measure to minimize
<br />off-site tracking of sediment by construction vehicles; and vegetated filter strips.
<br />(f) Material and waste management. Measures to ensure the proper storage of [tex-iE
<br />xiate~ial] potential pollutants and prevent the discharge of pollutants associated with
<br />construction materials and wastes shall be implemented.
<br />(g) Timing of control measure implementation. Timing of control measure implementation
<br />shall be in accordance with the approved erosion control plan if such plan is required. At
<br />a minimum, when there aze no approved erosion control plans, disturbed areas of a
<br />construction site that will not be redisturbed for 21 days or more will be stabilized
<br />(grassed, graveled or other measures) by no later than the 14th day after last disturbance.
<br />Section 10-4. Hazardous conditions.
<br />(a) Whenever the director of public works determines that any existing excavation, fill,
<br />grubbing, stockpiling or grubbed vegetation has become a hazard to property, or
<br />adversely affects the safety, use, or stability of a public way or drainage channel, the
<br />owner of the property upon which the excavation, fill, grubbing, [er] stockpiling or
<br />grubbed vegetation is located, or other person or agent in control of said property [~tpen

<br />requirements of this chapter.
<br />(b) The director of public works or the director's authorized representatives are hereby
<br />authorized to enter any property to determine or to enforce the provisions of this chapter:
<br />Section 10-5. Agricultural Operations.
<br />(a) Agricultural operations, including ranching incidental to or in conjunction with crop or
<br />livestock production, that conform with soil conservation practices and are in accordance
<br />with an actively pursued comprehensive conservation plan, prepared by an [~]
<br />engineer or conservationist, shall be exempt from the provisions of this chapter provided:
<br />(1) Such operations do not alter the general and localized drainage patterns with
<br />respect to abutting properties based on best available information.
