SWPPP Mmimum Elements � .gW'B ��611.�' � 1: Preserve Vegetation and Mark Cleanng Limils G�p( The first step in the construction process is for the contractor to,�latf fenc the limits of . clearing/disturbance prior to any other construction activity. The engin ring plans locate �-� OZ and provide the square footages for lhe areas of grading, clearing, impervious suriaces ��02 and un-disturbed areas on the proposed site. Large amounts of natural vegetation will be _ t 7- preserved on this project. Approximately 63% oi the entire site will be cleared or disturbed �i�L for this project. 2: Establish Construction Access The SWPPP calls for the proposed construction entrance to be installed as ihe second � step after the staking of clearing limits. Since this project will utilize the level area on the C' (�S properly to the south this feature will not require any excessive grading lo install, will be available immediately and may require some maintenance to ensure proper function during the site work. At this time winter work is expected during the wet season. 3: Control Flow Rales This project is below the thresholds requiring Oow control for the project. ✓ 4: Install Sediment Controls This site SWPPP proposes to conslrucUmaintain a gravel entrance, vegetatve buffer, silt fencing and retention of lhe existing vegetation that will provide a vegetaled strip between the cleared areas and any downslope property line. The construction ot these teatures C�n�� should be completed before the clearing and grading of the site. Mulch will also be used on the exposed soil as necessary to limit erosion. ��5 C. 2341_ , ..11 ��Sl. 5: Stabilize Soils � vo SI�C-�Z ��'•�'� � The "Construction Sequence" calls (or the st bilization of soils that remain unworked for , o I certain lengths of time based ra.ihE tim�eai' StabilizaUon techniques may include but L�Z ' not limited to mulchmg, plastic sheeting or hydroseeding, notes have been added to the �� Z) , plan regarding protection for the stock pile area if necessary. A stockpile area has been identified on the SWPPP and is setback a minimum of 25-feet From any down slope C� Z�C�� property line. ! �� I 6: Protect Slopes � , All disturbed slopes on site dunng construction are required to be protected with mulch or i other means as specfied in the construction sequence. No conceMrated runoH or C 13V signdicant amounts of sheet flow w�ll be directed to new cut or fdl slopes during C Zp� I consiruction. �� I 7: Protect Drain Inlets No new or existing culverts are proposed or affeded by this project.✓ 8: Stabilize Channels and Oullets No new channels or outlets are proposed for fhis site except for the level spreaders and footmg/rockery drams which will not create a concentrated flow condition ✓ Chmook SFR - -- --� ------- 12-013��' - Jan 2012 Page��/�`) ! .. «
