Preliminary Stormwater Site Plan Everett,WA <br /> 111 <br /> sloped (avg. 10%). In consideration of the area topographyand site soils, erosion control <br /> p g <br /> and sediment trapping measures will need to be closely monitored during construction. <br /> 111 <br /> The following structural items will likely be used to control erosion and sedimentation <br /> ' processes: <br /> • Stabilized construction entrance <br /> • Filter fabric fences <br /> • Cover measures <br /> • Haul Road and Staging areas <br /> • Temporary Interceptor Swales/Rock Check Dams <br /> • Sediment Ponds <br /> C. Permanent Erosion Control and Site Restoration <br /> Grass or ground cover will be planted on all exposed areas with side slopes greater than <br /> 3H:1V. <br /> D. Inspection Sequence (weekly and after major rainfalls) <br /> E. Control of Pollutants Other Than Sediments <br /> Pollutants shall be controlled on the work site with a Fuel Management Area per the <br /> Department of Ecology. This shall include a centralized area for equipment, concrete <br /> truck washing and temporary storage of debris and stockpiled materials. <br /> F. Utilities <br /> ' New utilities will be coordinated with the individual utility contacts. Erosion and sediment <br /> controls will be sequenced for construction activities to ensure erosion and sediment <br /> transport does not occur during utility installation. Temporary systems are not to be <br /> removed until permanent systems are "on-line" and approved by inspector. <br /> I <br /> 1 <br /> I <br /> 1 <br /> PACLAND Job# 50175001 Page 6 <br />
