Silver Lake Plaza <br />1. CONSTRUCTION STORM WATER POLLUTION <br />PREVENTION ELEMENTS <br />Element #1: Mark Clearing Limits <br />Clearing limits have been shown on the SWPPP Plan. <br />Selected BMP(s) - C103: High Visibility or Metal Fence <br />Element #2: Establish Construction Entrance <br />A temporary construction entrance at the southwest corner of the site connecting to <br />19th Avenue SE has been shown on the SWPPP plan. All vehicles shall be free of <br />debris prior to leaving the site. <br />Selected BMP(s) - C105: Stabilized Construction Entrance/Exit <br />Element # 3: Control Flow Rates <br />Flow rates during construction are to be contained through the installation of <br />temporary silt fencing on the south and west sides of the site. <br />Selected BMP(s) — Not Applicable <br />Element # 4: Install Sediment Controls <br />Sediment controls mainly consist of installation of a temporary silt fencing on the <br />south and west sides of the site. <br />Selected BMP(s) — C233: Silt Fence <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 roller <br />or bulldozer. Long-term methods consist of straw covering over the soils (this is in <br />the case of the project becoming dormant for greater than 1 month). At this time no <br />wintertime grading or construction activities will occur. During construction periods <br />longer than 1 working week (7 days) where the soils are exposed and un-worked will <br />use the proscribed methods in the Storm Water Management Manual for Western <br />Washington to reduce sedimentation transported offsite. If winter grading is <br />conducted, all exposed soils shall be covered within 2 days. <br />Selected BMP(s) — C120: Temporary and Permanent Seeding <br />C 121: Mulching <br />Element # 6: Protect Slopes <br />No steep slopes exist on -site; steep slope protection is not required. Any slopes <br />requiring stabilization will receive temporary or permanent seeding. <br />Selected BMP(s) - C120: Temporary and Permanent Seeding <br />Element # 7: Protect Drain Inlets <br />All catch basins within 500 feet downstream of the site will be protected with catch <br />basin sediment inserts. <br />Selected BMP(s) — C220: Storm Drain Inlet Protection <br />JOB NO: 15-1415-A <br />
