AE CONSTRUCTION SFR <br />1. CONSTRUCTION STORM WATER POLLUTION <br />PREVENTION ELEMENTS <br />Element #1: Mark Clearing Limits <br />Clearing limits have been shown on the Temporary Erosion and Sedimentation <br />Control Plans. <br />Element #2: Establish Construction Entrance <br />It has been shown that the current driveway entrance will be used as a temporary <br />construction entrance. All vehicles shall be free of debris prior to leaving the site. <br />Element # 3: Control Flow Rates <br />Flow rates during construction are to be contained through the installation of silt <br />fencing along the eastern clearing limits. <br />Element # 4: Install Sediment Controls <br />Sediment controls mainly consist of installing silt fencing along the eastern <br />clearing limits. <br />Element # 5: Stabilize Soils <br />All soils disturbed during site grading will be stabilized by use of the most <br />appropriate BMP method available. These consist of short-term and long-term <br />solutions. Short-term methods consist of compaction of the soils by vibratory <br />roller or bulldozer. Long-term methods consist of straw covering over the soils <br />(this is in the case of the project becoming dormant for greater than 1 month). At <br />this time no wintertime grading or construction activities will occur. During <br />construction periods longer than 1 working week (7 days) where the soils are <br />exposed and un-worked will use the proscribed methods in the Storm Water <br />Management Manual for Western Washington to reduce sedimentation <br />transported offsite. If winter grading is conducted, all exposed soils shall be <br />covered within 2 days. <br />Element # 6: Protect Slopes <br />No steep slopes exist on the proposed site; therefore, slope protection is not <br />needed. <br />Element # 7: Protect Drain Inlets <br />No known downstream inlets exist in the immediate downstream vicinity; inlet <br />protection is not required. <br />Element # 8: Stabilize Channels and Outlets <br />The need for channel stabilization is not expected but, existing channels or <br />drainage outlets located within 500-feet of the property of the property should be <br />routinely inspected for debris that may dam and/or aid erosion. <br />JOB NO: 19-1821-A <br />
