PAC _ <br /> BMP ES.70 has been implemented to the foreseeable extent in the permit/construction <br /> documents. It is the responsibility of the project CESCL to propose additional soil <br /> stabilization measures as warranted by site conditions. <br /> BMP ES.80 Street Cleaning <br /> Periodic street cleaning shall be provided to remove any sediment that may have been <br /> tracked out. Sediment should be removed by shoveling or sweeping and carefully <br /> removed to a suitable disposal area where it will not be re-eroded. Additional street <br /> cleaning may be required as directed by the city public works inspector. Special care <br /> should be taken to reduce sediments from entering storm drains connected to salmon <br /> streams. The use of vacuum sweepers is encouraged. <br /> BMP ES.80 has been included in the permit/construction documents.

Refer to Appendix C for the sizing of <br /> the sedimentation tank. <br /> SECTION 4 — Minimum Requirement #3 <br /> 4.1 Source Control of Pollution <br /> The City of Everett Source Control Activity Worksheet has been completed and included <br /> in Appendix D of this report. The required BMPs for the anticipated site activities are <br /> also included within Appendix D. <br /> SECTION 5 — Minimum Requirement #4 <br /> 5.1 Preservation of Natural Drainage Systems and Outfalls <br /> Currently stormwater which is generated onsite flows through swales to the combined 8" <br /> sewer system in the middle of the 10th Street right of way north of the site. When <br /> redeveloped, the site will maintain the existing discharge point. Since the project is <br /> located within a combined sewer area, no flow control or water quality is required. Based <br /> on reports from the City of Everett this system does have capacity issues during high <br /> flows. The project is proposing to provide bioretention and intensive landscaping to <br /> reduce peak runoff from the site in accordance with Minimum requirement#5. <br /> Starbucks Page 5 <br /> Broadway and 10th Store <br /> Drainage Report <br /> May 2014 <br />
