• <br /> 2.1.7 Element 7: Protect Drain Inlets <br />• All storm drain inlets and culverts made operable during construction shall be protected <br /> to prevent unfiltered or untreated water from entering the drainage conveyance system. <br /> However, the first priority is to keep all access roads clean of sediment and keep street <br /> wash water separate from entering storm drains until treatment can be provided. Storm <br /> Drain Inlet Protection (BMP C220)will be implemented for all drainage inlets and <br />• culverts that could potentially be impacted by sediment-laden runoff on and within 500 <br /> feet downstream of the project site. <br /> List and describe BMPs: BMP C220 —Storm Drain Inlet Protection <br />• Installation Schedules: <br /> Inspection and Maintenance plan: <br /> Responsible Staff: <br />• <br /> 2.1.8 Element 8: Stabilize Channels and Outlets <br /> Where site runoff is to be conveyed in channels, or discharged to a stream or some other <br />• natural drainage point, efforts will be taken to prevent downstream erosion. <br /> Provide stabilization, including armoring material, adequate to prevent erosion of outlets, <br /> adjacent stream banks, slopes, and downstream reaches, will be installed at the outlets of all <br /> conveyance systems. <br /> List and describe BMPs: BMP C207 — Rip Rap <br /> BMP C208 —Triangular Silt Dike <br /> Installation Schedules: <br /> Inspection and Maintenance plan: <br /> Responsible Staff: <br />• <br />• <br />• Page 19 <br />
