8. RUN-OFF TREATMENT <br /> As noted before this project proposes to install a total of 4,078 sf of new PGIS to serve this <br /> project based on the Owner/Applicants plans. <br /> Per COE 2010 Stormwater Manual "Minimum Requirements 6: Runoff Treatment— <br /> Requirements" a project is required to provide runoff treatment if: <br /> (a) Projects in which the total effective, pollution-generating impervious surface (PGIS) is <br /> 5,000 square feet or more in a threshold discharge area of the project; or <br /> (b) Projects in which the total of pollution-generating pervious surface (PGPS) is three- <br /> quarters of an acre or more in a threshold discharge area, and from which there is a <br /> surface discharge into a natural or man-made conveyance system from the site. <br /> As shown in the area summary above this project does not propose to construct 5,000 sf <br /> or more of PGIS so treatment facilities are not required. However, on-site stormwater <br /> BMPs are required, refer to Section 7 of this report for a detailed discussion of the BMPs <br /> proposed. <br /> 9. FLOW CONTROL <br /> Refer to Section 7 and Appendix A for detailed design information. <br /> Uplands Short Plat 14-0108 <br /> June, 2016 Page 12 <br />
