x � <br /> Exposed and un-worked soils shall be stabilized with the application of effective <br /> BMPs to prevent erosion throughout the life of the project. <br /> Apply temporary hydro-seed to exposed and un-worked soils, according to the <br /> approved construction plans, as needed to prevent erosion during site grading. <br /> Apply permanent hydro-seed to areas at final grade as site grading is completed. <br /> Apply mulching to exposed and un-worked soils, according to the approved <br /> construction plans, as needed to prevent erosion during site grading. Maintain until <br /> site grading is completed and permanent hydro-seed is applied. <br /> Cover stockpiles with plastic sheeting, according to the approved construction <br /> plans, as needed to prevent erosion during site grading. Maintain until stockpiles <br /> are removed from site. <br /> Element#6-Protect Slopes <br /> All cut and fill slopes will be designed, constructed, and protected in a manner than <br /> minimizes erosion. The following specific BMPs will be used to protect slopes for this <br /> project. <br /> Element#7—Protect Drain Inlets <br /> All storm drain inlets and culverts made operable during construction shall be protected to <br /> 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. <br /> 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 /> Element#9—Control Pollutants <br /> All pollutants, including waste materials and demolition debris,that occur onsite <br /> shall be handled and disposed of in a manner that does not cause contamination of <br /> stormwater. Good housekeeping and preventative measures will be taken to ensure <br /> that the site will be kept clean,well organized, and free of debris. <br /> Element#10—Control Dewatering <br /> There will be no dewatering expected as part of this proposal. If it occurs, Baker tanks will <br /> be used for dewatering. <br /> Element#11 —Maintain BMPs <br /> All temporary and permanent erosion and sediment control BMPs shall be maintained and <br /> repaired as needed to assure continued performance of their intended function. <br /> Maintenance and repair shall be conducted in accordance with each particular BMP's <br /> specifications. Visual monitoring of the BMPs will be conducted at least once every <br /> calendar week and within 24 hours of any rainfall event that causes a discharge from the <br /> site. If the site becomes inactive, and is temporarily stabilized, the inspection frequency <br /> will be reduced to once every month. All temporary erosion and sediment control BMPs <br /> shall be removed within 30 days after the final site stabilization is achieved or after the <br /> Insight Engineering Co. -Stormwater Site Plan 6/22/2022 <br /> - 15 - <br />
