I <br />Everett LDS Parking Lot Expansion <br />Storm Drainage Report <br />4. Analysis and Design of Required Erosion and Sediment Control BMPs <br />Silt fencing is proposed along the downstream perimeter of the disturbed area (northeast comer of the <br />property). Inlet protection will be installed in the existing catch basins near disturbed portions of the site. <br />Site management for ESC measures are not limited tc the above listed best management practices (BMPs). <br />The contractor shall provide additional BMPs as appropriate for changing site conditions. <br />It is anticipated that there is little potential for erosion and sedimentation ofonsite earthwork to adversely u <br />impact downstream properties. <br />5.
