swppp narrative <br /> The intent of this section is to provide the information necessary to support the engineering <br /> plans in order to implement a design that will; reduce, eliminate or prevent the discharge of <br /> stormwater pollutants, meet or exceed the water quality and sediment management <br /> standards for the County and State, and prevent adverse impacts to the receiving waters <br /> for this project. <br /> A. SITE GRADING/EROSION CONTROL RISK ASSESSMENT <br /> Area proposed to be cleared/worked: 0.51 acres <br /> Average slope for the site: >5% (Area of Disturbance Only) <br /> Erosion Hazard of Soil Low <br /> Critical Areas downslope Yes <br /> Site is upstream of an ESA Stream No <br /> Based on the above information and the fact that the area of the site to be disturbed is flat <br /> and construction site runoff will pass through silt fencing or other perimeter filtration features <br /> prior to leaving the site, and that if site conditions warrant, additional BMP's can be <br /> implemented as corrective measures the Risk Category for this site is Low Risk. <br /> B. SWPPP MINIMUM ELEMENTS <br /> 1: Preserve Vegetation and Mark Clearing Limits <br /> The first step in the construction process is for the contractor to fence the limits of <br /> clearing/disturbance (BMP C103) prior to any other construction activity. The engineering <br /> plans locate and provide the square footages for the areas of grading, clearing, impervious <br /> surfaces and un-disturbed areas on the proposed site. As much of the natural vegetation <br /> as possible will be preserved on this project (BMP C101). Approximately 71% of the site <br /> may be cleared or disturbed for this project. <br /> 2: Establish Construction Access <br /> The SWPPP calls for the proposed construction entrance(BMP C105)to be installed as the <br /> second step after the staking of clearing limits. Since the existing gravel driveway will be <br /> used as a construction entrance,this access will be provided immediately.At this time winter <br /> work is expected during the wet season. <br /> 3: Control Flow Rates <br /> This is except from the flow control requirement. <br /> Kennedy SFR 17-1002 <br /> October 2017 Page 6 <br />
