<br />D. Tracking. Vehicle tracking of sediment onto paved surfaces must be <br />removed by street sweeping as needed to prevent discharge of sediment laden <br />water from entering the City storm sewer system. <br /> <br />E. Drain inlet protection. All storm drain inlets shall be protected during <br />construction until final establishment has been accomplished or until approval <br />from the City. <br /> <br />F. Site erosion control. The following criteria (1 through 4) apply only to <br />construction activities that result in storm water leaving the site. <br /> <br />1.) Channelized runoff from adjacent areas passing through the site shall be <br />diverted around disturbed areas, if practical. Otherwise, the channel shall <br />be protected as described below. Sheetflow runoff from adjacent areas <br />greater than 10,000 square feet in area shall also be diverted around <br />disturbed areas, unless shown to have resulted runoff rates ofless than <br />0.5 ft./sec. across the disturbed area for the one year storage. Diverted <br />runoff shall be conveyed in a manner that will not cause erosion, scour, <br />or flooding of the conveyance at receiving channels. <br /> <br />2.) All activities on the site shall be conducted in a logical sequence to <br />minimize the area of bare soil exposed at anyone time. <br /> <br />3.) Runoff from the entire disturbed area on the site shall be controlled by <br />meeting either subsections a. and b. or a. and c. <br /> <br />a. All exposed soil areas with a continuous positive slope within 200 <br />lineal feet of a surface water, must have temporary erosion protection or <br />permanent cover for the exposed soil areas year round, according to the <br />following table of slopes and time frames: <br /> <br />TWe of slope <br />Steeper than 3: 1 <br />10:1 to 3:1 <br />Flatter than 10: 1 <br /> <br />Time <br />7 days <br />14 days <br />21 days <br /> <br />b. For sites with more than ten (10) acres disturbed at one time, or if a <br />channel originates in the disturbed area, one or more temporary or <br />permanent sedimentation basin shallbe constructed. Each sedimentation <br />basin shall have a surface area of at least one percent of the area draining <br />to the basin and at least three feet of depth and constructed in accordance <br />with accepted design specifications. Sediment shall be removed to <br />maintain a depth of three feet. The basin discharge rate shall also be <br />sufficiently low as to not cause erosion, scour, or flooding along the <br />discharge channel or the receiving water. <br />
