Preserve Vegetation/Mark Clearing Limits: The clearing limits are indicated on the plan sheet. Furthermore, clearing and grading will be limited to only areas that need to be disturbed for grading/construction of the site and frontage improvements. Construction will require regarding the entire site. Field marking the clearing limits shall be completed prior to clearing and grading activities. BMP's: Preserve Natural Vegetation (VEG) 2. Establish Construction Access: Access to the construction site shall be limited to the rock construction entrance. The rock construction entrance shall be installed off of the Street to provide access to the construction vehicle/equipment staging and employee parking areas. BMP's: Rock construction entrance (CE) See detail sheet C,51 5. Control of Flow Rates: Storm water detention: No detention is proposed for the site since the work should be completed in a short period of time. BMP's None Proposed 4. Installation of Sediment Controls: Sediment control will be provided through a combination of filtration through the surround on -site vegetation, or filter fence if required. , BMP's: Silt Fence (SF) Sediment Trap (ST) I 5. Soils Stabilization: Temporary and permanent sail stabilization wi I I be provided. Temporary stabilization wi I I be provided through the application of straw and/or plastic sheeting to exposed, worked earth. From October I until April 50, no exposed soil may remain exposed and unworked for more than two days; after May I, no exposed soil may remain exposed and unworked for more than seven days. BMP's: Straw Covering, Plastic Sheeting, Final Landscoping(as required) 6. Slope Protection: Stock piles shall be protected from erosion through cover and prevention of concentrated surface runoff flows on steep slopes as required. BMP's: Plastic Sheeting, (AS REQUIRED) 7. Protection of Permanent Drain Inlets: Inlet protection will be provided for all catch basins. BMP's: Inlet Protection (IF) See detail sheet (AS REQUIRED) 8. Stabilization of Channels and Outlets: All channel slopes shall be constructed and protected against erosion in accordance with County code. (None Required) q. Pollutant Control: Po I lutants shall be controlled through the on -site BMP's proposed above. 10. Dewatering Control: De -watering: Interception of the water table is expected to occur. (NOT REQUIRED) 11. BMP Maintenance: All BMP's and SWPPP elements shall be inspected daily and maintained as required. 12. Project Management: The project shall be managed in a cooperative effort by the project manager, contractor, engineer, and the county inspector. During the construction process, if unforeseen issues arise that cannot be resolved on site, construction activity (other than SWPPP maintenance) shall be halted and the owner's representative and the project engineer are to be contacted and informed of the situation. TBD 15. Protect on -site stormwater management bmps for runoff from roofs and other hard surface on -site stormwater management bmps used for runoff from roofs and other hard surfaces include: full dispersion, roof downspout full infiltration or dispersion systems, perforated stubout connections, rain gardens, bioretention systems, permeable pavement, sheetflow dispersion, and concentrated flow dispersion. the areas on the site to be used for these bmps shall be protected from siltation and compaction during construction by sequencing the construction in a fashion to install these bmps at the latterpart of the construction grading operations, by excluding equipment from the mps and the associated areas, and by using the erosion and sedimentation control bmps listed below. relevant bmp's burp c 102: buffer zone 0 C TY OR RENTON Planning/Building/Public Works Dept.
