All limits of clearing and areas of vegetation preservation as prescribed on the plan shall be clearly flagged in the field and observed during construction. 2. All required sedimentation/erosion control facilities must be constructed and in operation prior to land clearing and/or other construction to insure that sediment laden water does not enter the natural drainage system. All erosion and sediment facilities shall be maintained in a satisfactory condition until' such time that clearing and/or construction is completed and potential for on -site erosion has passed. The implementation, maintenance, replacement and additions to erosion/ sedimentation control systems shall be the responsibility of the permittee. 3. The erosion and sedimentation control systems depicted on this drawing are intended to be minimum requirements to meet anticipated site conditions. As construction progresses and unexpected or seasonal conditions dictate, facilities will be necessary to insure complete siltation control in the proposed site. During the coarse of construction, it shall be the obligation and responsibility of the permittee to address any new conditions that may be created by his activities and to provide additional facilities over and above minimum requirements as may be needed to protect adjacent properties and water quality of the receiving drainage system. 4. Approval of this plan is for erosion/sedimentation control only. It does not constitute an approval of storm drainage design, size, nor.location of pipes, restrictors, channels of retention facilities. 5. All streets shall be kept clean in a manner directed by the city eogineer. 6. Fill will be placed on existing natural ground. GENERAL NOS 1. All workmanship and materials shall conform to the City of Auburn's requirements and specifications.. 2. Standard specifications shall be 1951 APWA as modified by the City of Auburn. 3. A copy of these approved plans shall be on -site during construction. 4. Prior to starting construction, the contractor shall call one call (1-800-424-5555) for utility locations, water, sanitary sewer, storm sewer, gas, power, telephone and television. 5. During construction, contractor shall be required to control on -site stormwater runoff by using temporary erosion/siltation control procedures. No sediment laden storm water shall be allowed to discharge into the City of Auburn's storm drainage system or adjacent property. CONSTRUCTION SEQUENCE= I. Construct Perimeter Ditches as required. 2. Install Temporary Construction Entrance. 3. Install Miraf'1 Filter Fabric Fence as shown on plan. 4. Clearly Flag all Areas to Remain Undisturbed. 5. Fill Site to Required Grades 6. Install Additional Erosion Control Measures as needed during the Construction Phase. •w FILTER FABRIC STAPLES OR 2 x 2 x 14 GAGE MATERIAL, MIRAFI WIRE RINGS (TYP) WELDED WIRE FABRIC 140, OR EQUAL OR EQUAL II II � N li11 II II I� U v 11 - N Z0 II r� U U ., U II II jj a IIN �I 11 II II II II II U U U 2' x 4' DOUGL A S FIR AT 4' O.C.
