S � <br /> temporary BMPs are no longer needed. Trapped sediment shall be removed or stabilized <br /> on site. Disturbed soil resulting from removal of BMPs or vegetation shall be permanently <br /> stabilized. <br /> Element#12 —Manage the Project <br /> Erosion and sediment control BMPs for this project have been designed based on the <br /> following principles: <br /> Design the project to fit the existing topography, soils, and drainage patterns; Emphasize <br /> erosion control rather than sediment control; Minimize the extent and duration of the area <br /> exposed; Keep runoff velocities low; Retain sediment on site; Thoroughly monitor site and <br /> maintain all ESC measures and Schedule major earthwork during the dry season. The <br /> SWPPP shall be modified as necessary to include additional or modified BMPs designed to <br /> correct problems identified. Revisions to the SWPPP shall be completed within seven(7) <br /> days following the inspection. <br /> 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 <br /> hard surfaces include: full dispersion, roof downspout full infiltration or <br /> dispersion systems, perforated stubout connections, rain gardens, <br /> bioretention systems, permeable pavement, sheetflow dispersion, and <br /> concentrated flow dispersion. The areas on the site to be used for these <br /> BMPs shall be protected from siltation and compaction during construction <br /> by sequencing the construction in a fashion to install these BMPs at the <br /> latter part of the construction grading operations, by excluding equipment <br /> from the BMPS and the associated areas, and by using the erosion and <br /> sedimentation control BMPs listed below. Additional requirements for <br /> protecting these BMPs during the construction process, testing functionality, <br /> and restoring functionality are needed at the final stage of the construction <br /> process. <br /> Relevant BMPs <br /> BMP C 102: Buffer Zone BMP <br /> C103: High Visibility Fence BMP <br /> C200: Interceptor Dike and Swale BMP <br /> Insight Engineering Co. -Stormwater Site Plan 6/22/2022 <br /> - 16- <br />
