3.1.2 Element #2 — Establish Construction Access <br />Install stabilized construction access points prior to grading operations that expose bare soil to <br />construction equipment. Limit access points to the fewest number possible whenever feasible. <br />It is anticipated that one entrance will be sufficient. If sediment is tracked offsite, roads are to <br />be cleaned thoroughly at the end of each day by sweeping or shoveling followed by sweeping. <br />Sediment removed will be transported and stabilized onsite. When construction traffic must <br />operate over un-stabilized areas during wet periods, a wheel wash should be used prior to <br />exiting the subject site, while wash water should be treated onsite, or discharged to a sanitary <br />sewer if allowed by the City of Everett. If streets are washed with water, collect and treat wash <br />water prior to discharge. <br />Construction access or activities occurring on unpaved areas shall be minimized, yet where <br />necessary, access points shall be stabilized to minimize the tracking of sediment onto public <br />roads, and wheel washing, street sweeping, and street cleaning shall be employed to prevent <br />sediment from entering state waters. All wash wastewater shall be controlled onsite. The <br />specific BMPs related to establishing construction access that will be used on this project <br />include: <br />• BMP C105: Stabilized Construction Entrance <br />• Street Sweeping <br />3.1.3 Element #3 — Control Flow Rates <br />In order to protect the surrounding properties and public streets, any storm water discharge <br />from the subject site will be controlled. Based on the relatively small size of the subject site and <br />proposed work areas, flow rate controls are not anticipated to be utilized on this project. <br />3.1.4 Element #4 — Install Sediment Controls <br />All storm water runoff from disturbed areas shall pass through an appropriate sediment <br />removal BMP before leaving the subject site or prior to being discharged to an infiltration <br />facility. In order to best accomplish this, the duff layer, native topsoil, and natural vegetation <br />will remain in an undisturbed state to the maximum extent practical. If it is not practicable to <br />retain the duff layer in place, it should be stockpiled onsite, covered to prevent erosion, and <br />replaced immediately upon completion of the ground disturbing activities.
