the required setbacks. Downspout Dispersion is infeasible because the site cannot provide <br /> ' the required vegetated flow paths. Perforated stub out connections are also not feasible. <br /> The runoff from the roof will be tight lined to a detention system on the south side of the <br /> project to continue to City's combined sewer system. <br /> ' 1. The purpose of this SWPPP is to describe the proposed construction <br /> activities and all temporary and permanent erosion and sediment <br /> control (TESC) measures, pollution prevention measures, <br /> ' inspection/monitoring activities, and recordkeeping that will be <br /> implemented during the proposed construction project. The <br /> objectives of the SWPPP are to: <br /> ' 2. Implement Best Management Practices (BMPs) to prevent erosion <br /> and sedimentation, and to identify, reduce, eliminate or prevent <br /> ' stormwater contamination and water pollution from construction <br /> activity. <br /> ' 3. Prevent violations of surface water quality, ground water quality, or <br /> sediment management standards. <br /> ' 4. Prevent, during the construction phase, adverse water quality <br /> impacts including impacts on beneficial uses of the receiving water <br /> by controlling peak flow rates and volumes of stormwater runoff at <br /> the Permittee's outfalls and downstream of the outfalls. <br /> 5. This SWPPP was prepared using the Ecology SWPPP Template. <br /> ' This SWPPP was prepared based on the requirements set forth in the <br /> Construction Stormwater General Permit and in the Stormwater <br /> Management Manual for Western Washington (SWMMWW 2014). <br /> The 13 BMP Elements <br /> ' Element#1 —Mark Clearing Limits <br /> To protect adjacent properties and to reduce the area of soil exposed to <br /> 1 construction,the limits of construction will be clearly marked before land- <br /> disturbing activities begin. <br /> ' Element#2—Establish Construction Access <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 <br /> ' Insight Engineering Co. -Stormwater Site Plan 12/30/20 <br /> - 15 - <br /> 1 <br />
