5. MINIMUM REQUIREMENTS <br /> MINIMUM REQUIREMENT#1: PREPARATION OF STORMWATER SITE PLANS <br /> This project proposes to construct new impervious surfaces in excess of the minimum <br /> threshold so a final stormwater site plan and report has been prepared with this submittal. <br /> MINIMUM REQUIREMENT#2: CONSTRUCTION STORMWATER POLLUTION <br /> PREVENTION (SWPPP) <br /> 1: Mark Clearing Limits <br /> One of the first steps in the "Construction Sequence" included on the clearing and <br /> grading plan sheets is for a surveyor to stake the limits of clearing and to have <br /> construction flagging/fencing or silt fencing placed along the limits prior to any other <br /> construction activity. <br /> 2: Establish Construction Access <br /> The SWPPP calls for the proposed construction entrance to be installed as the second <br /> step after the staking of clearing limits. A detail is provided on the plans. <br /> 3: Control Flow Rates <br /> This project will retain as much existing vegetation as possible and will be re-vegetated <br /> after grading is complete. In addition, the swale will be used as an interceptor swale <br /> during construction to trap sediment and attenuate flows. Therefore, the flow restrictors <br /> will be in place to regulate runoff during construction. This will protect the downstream <br /> system from higher flows during construction. <br /> 4: Install Sediment Controls <br /> This site and SWPPP proposes to construct a construction entrance and silt fencing to <br /> collect and contain the sediment on this site. In addition, inlet filters will be installed in the <br /> new catch basins on the site. These features are intended to minimize the opportunity for <br /> sediment to leave the site via stormwater or on vehicles. The construction of these <br /> features is one of the first items required in the "Construction Sequence". Mulch will also <br /> be used on the exposed soil as necessary to limit erosion. <br /> 5: Stabilize Soils <br /> The "Construction Sequence" and "TESC Notes" call for the stabilization of soils that <br /> remain unworked for certain lengths of time based on the time of year. Stabilization <br /> techniques may include but not limited to mulching, plastic sheeting or hydroseeding, <br /> notes have been added to the plan regarding protection for the stock pile area if <br /> necessary. <br /> 6: Protect Slopes <br /> All slopes on site during construction are required to be protected with mulch or other <br /> means as specified in the construction sequence. <br /> 7: Protect Drain Inlets <br /> All new catch basins will have inlet filters installed to protect the conveyance system. <br /> PSKC Nassau 12-0411 <br /> July 2012 Page-8 <br />
