4. Sediment controls will be shown on the plan and consists of the gravel <br /> construction driveway entrance, silt fences and replanting grass/lawn on all <br /> disturbed areas and CB protection to structures downstream of driveway. <br /> 5. Soil stabilization notes will be added to the plans; <br /> 6. The site has moderate slopes to protect. The intent is to install a silt-fencing <br /> and provide ground cover and or temporary plastic sheeting for all denuded <br /> areas. <br /> 7. See#4 above; <br /> 8. The downstream storm system will be protected by providing downspouts at <br /> roof locations and piped to the existing catch basins along Broadway. During <br /> construction CB protection will be provided at the existing downstream Catch <br /> Basin. <br /> 9. Standard construction notes will be added to the plans; there does not appear <br /> to be a problem with controlling pollutants; On-site pollutant management <br /> from construction activities will take place. <br /> 10. No dewatering issues are anticipated; however dewatering measures will take <br /> place as needed. <br /> 11. Standard construction plans and erosion control notes will be added to the <br /> plan. These notes require maintaining the BMPs. <br /> 12. The project is small, so no phasing, seasonal work limitations or <br /> clearing/grading restrictions were deemed necessary. <br /> Requirement#3- Source Control of Pollution <br /> This project is simple, straight forward and short in duration. There are no pollutants on- <br /> site that water must not come in contact with, except for sedimentation due to soil <br /> erosion. The main source of stormwater will come into contact with the native soil. The <br /> protections are noted above. <br /> Requirement#4-Preservation of Drainage Systems and Outfall <br /> The project will maintain and preserve the existing drainage path. The on-site stormwater <br /> shall be collected and discharged to the existing CB system along Broadway the natural <br /> drainage path downstream of the project site. Tight lining of downspouts and footing <br /> drains will be utilized to route stormwater to the base of the site without causing erosion <br /> or drainage impacts to the downstream neighboring properties. <br /> UPSTREAM DRAINAGE <br /> The site has no upstream drainage onto the property as the land slopes away from the <br /> property. <br /> DOWNSTREAM DRAINAGE <br /> Stormwater runoff collects onsite and sheet flows to the existing CB on Broadway in the <br /> curb gutter and sidewalk with storm drainage conveyance system. No impacts to the <br /> i ' /xe +, 4 } <br /> .� <br />
