Element 13 - Protect on-site stormwater management BMPs for runoff from roofs <br /> and other hard surfaces <br /> On-site stormwater management BMPs used for runoff from roofs and other hard surfaces include: full <br /> dispersion, roof downspout full infiltration or dispersion systems, perforated stubout connections, rain <br /> gardens, bioretention systems, permeable pavement, sheetflow dispersion, and concentrated flow <br /> dispersion. The areas on the site to be used for these BMPs shall be protected from siltation and <br /> compaction during construction by sequencing the construction in a fashion to install these BMPs at the <br /> latter part of the construction grading operations, by excluding equipment from the BMPs and the <br /> associated areas, and by using the erosion and sedimentation control BMPs listed below. Additional <br /> requirements for protecting these BMPs during the construction process, testing functionality, and <br /> restoring functionality are needed at the final stage of the construction process and are included in the <br /> specific BMP sections in the Snohomish County Drainage, Volume V. <br /> Check the BMPs you will use: <br /> ❑ C102 Buffer Zone <br /> ❑ C103 High Visibility Fence <br /> ❑ C231 Brush Barrier <br /> 13 C233 Silt Fence <br /> ❑ C234 Vegetated Strip <br /> Applicant Signature <br /> Small Project Stormwater Pollution Prevention Plan (SWPPP) Narrative and Plan Submittal Rev 3-18-16 10 <br />
