<br />A. All grading plans and building site surveys must be reviewed by the city for <br />effectiveness of erosion control measures in the context of the site <br />topography and drainage. <br /> <br />B. Sediment control measures must be properly installed by the builder before <br />construction activity begins. Such structures may be adjusted during dry <br />weather to accommodate short term activities, such as those that require the <br />passage of very large vehicles. As soon as this activity is finished or before <br />rainfall, the erosion and sediment control structures must be returned to the <br />configuration specified by the city. A sediment control inspection must then <br />be scheduled, and passed before a footing inspection will be done. <br /> <br />C. Diversion of channeled runoff around disturbed areas, if practical, or the <br />protection of the channel. <br /> <br />D. Easements. If a storm water management plan involves directing some or all <br />of the site's runoff, the applicant or his designated representative shall obtain <br />from adjacent property owners any necessary easements or other property <br />interests concerning the flowing of such water. <br /> <br />E. The scheduling of the site's activities to lessen their impact on erosion and <br />sediment creation, so as to minimize the amount of exposed soil. <br /> <br />F. Control runoff as follows (Either 1 and 2 or 1 and 3): <br /> <br />1.) Unless precluded by moderate or heavy snow cover (Mulching can <br />take place if a light snow cover is present.), stabilize all exposed <br />inactive disturbed soil areas within one hundred (100) feet of any <br />water of the state, or with in one hundred (100) feet any conveyance <br />(curb, gutter, storm sewer inlet, drainage ditch, etc.) to a water of the <br />state with sod, seed or weed free mulch. This must be done, if the <br />developer will not work the area for seven (7) days on slopes greater <br />than three (3) feet horizontal to one (1) foot vertical (3: 1), fourteen <br />(14) days on slopes ranging from 3:1 to 10:1 and twenty-one (21) days <br />for flatter slopes. <br /> <br />2.) For disturbed areas greater than five (5) acres construct temporary or <br />permanent sedimentation basins. Sedimentation basins must have a <br />minimum surface area equal to at least 1 % of the area draining to <br />basin, and be constructed in accordance with accepted design <br />specifications including access for operations and maintenance. Basin <br />discharge rates must also be controlled to prevent erosion in the <br />discharge channel. <br /> <br />a.) The applicant is required to obtain a National Pollutant Discharge <br />Elimination System/State Disposal System (NPDES/SDS) <br /> <br />Page 10 of21 <br />November 8, 2006 <br /> <br />Storm Water Pollution Control Ordinance <br />
