Install catch basin filters, according to the approved construction plans, as catch basins <br /> become operable. Maintain until all construction activities are completed. <br /> Element#5—Stabilize Soils <br /> Exposed and un-worked soils shall be stabilized with the application of effective BMPs to <br /> prevent erosion throughout the life of the project. <br /> Apply temporary hydro-seed to exposed and un-worked soils, according to the approved <br /> construction plans, as needed to prevent erosion during site grading. Apply permanent <br /> 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 construction <br /> plans, as needed to prevent erosion during site grading. Maintain until site grading is <br /> completed and permanent hydro-seed is applied. <br /> Cover stockpiles with plastic sheeting, according to the approved construction plans, as <br /> needed to prevent erosion during site grading. Maintain until stockpiles are removed from <br /> 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 shall be <br /> handled and disposed of in a manner that does not cause contamination of stormwater. <br /> Good housekeeping and preventative measures will be taken to ensure that the site will be <br /> 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 /> Insight Engineering Co. -Stormwater Site Plan 07/03/2019 <br /> - 17- <br />
