NOTES:

1. PROPOSED GRADES SHOWN DEPICT THE TOP OF INTERMEDIATE COVER ON WHICH THE LINER SYSTEMIS PLACED. TOP OF WASTE GRADES SHALL BE LOCATED 1 FOOT (MINIMUM) BELOW THE TOP OFINTERMEDIATE COVER. SEE THE SPECIFICATIONS AND DETAILS FOR THE LINER SYSTEM REQUIREMENTS.

2. ANY FENCE OR PART THEREOF OUTSIDE THE PROJECT LIMIT, INCLUDING SEDIMENTATION BARRIER,THAT IS DAMAGED OR REMOVED DURING THE COURSE OF THE WORK SHALL BE REPLACED ORREPAIRED BY THE CONTRACTOR UNLESS SPECIFICALLY WAIVED BY THE COUNTY AND SHALL BE LEFT INAS GOOD A CONDITION AS BEFORE THE START OF WORK.

3. CONTRACTOR SHALL REMOVE MULCH AND STRIP EXISTING VEGETATION WITHIN THEPROJECT AREA. THIS DRAWING REFLECTS PROPOSED GRADES WITHIN THE PROJECT AREAS ASDESIGNATED IN THE LEGEND. THE GRADING ALONG THE TOE OF SLOPE WILL PROVIDE THE ABILITY TOWELD THE CAP LINER TO THE BOTTOM LINER LOCATED ALONG THE TOP OF BERM. SEE DETAILSLOCATED IN THE PLAN SET.

4. REFER TO THE FIELD ENGINEERING AND SURVEY SPECIFICATION SECTION 1050 FOR DETAILEDREQUIREMENTS FOR VERIFICATION AND DOCUMENTATION OF INTERMEDIATE COVER PREPARATION.

5. ACREAGE NOTED ON DRAWING IS BASED ON PLANAR VIEW OF SITE. CONTRACTOR TO COMPUTE SLOPE SURFACE AND WASTE MATERIALS QUANTITIES ON BID FORM.

6. CONTRACTOR TO EXPOSE EDGE OF EXISTING LINER TO WHICH THE CAP LINER WILL BE WELDED. FINAL COVER OVER THE LINER WILL EXTEND BEYOND THESE POINTS.

7. INTERMEDIATE COVER ELEVATIONS SHOWN AT TOE OF SLOPE ARE TO INDICATE GENERAL BOTTOMLINER ELEVATIONS AND MAY NOT REFLECT ACTUAL ELEVATIONS.

APPROXIMATE LIMITS OF CLOSURECAPPING SYSTEM (30.0 ACRES)

PROJECT AREA


NOTES:

1. PROPOSED GRADES SHOWN DEPICT THE TOP OF INTERMEDIATE COVER ON WHICH THE LINER SYSTEMIS PLACED. TOP OF WASTE GRADES SHALL BE LOCATED 1 FOOT (MINIMUM) BELOW THE TOP OFINTERMEDIATE COVER. SEE THE SPECIFICATIONS AND DETAILS FOR THE LINER SYSTEM REQUIREMENTS.

2. ANY FENCE OR PART THEREOF OUTSIDE THE PROJECT LIMIT, INCLUDING SEDIMENTATION BARRIER,THAT IS DAMAGED OR REMOVED DURING THE COURSE OF THE WORK SHALL BE REPLACED ORREPAIRED BY THE CONTRACTOR UNLESS SPECIFICALLY WAIVED BY THE COUNTY AND SHALL BE LEFT INAS GOOD A CONDITION AS BEFORE THE START OF WORK.

3. CONTRACTOR SHALL REMOVE MULCH AND STRIP EXISTING VEGETATION WITHIN THEPROJECT AREA. THIS DRAWING REFLECTS PROPOSED GRADES WITHIN THE PROJECT AREAS ASDESIGNATED IN THE LEGEND. THE GRADING ALONG THE TOE OF SLOPE WILL PROVIDE THE ABILITY TOWELD THE CAP LINER TO THE BOTTOM LINER LOCATED ALONG THE TOP OF BERM. SEE DETAILSLOCATED IN THE PLAN SET.

4. REFER TO THE FIELD ENGINEERING AND SURVEY SPECIFICATION SECTION 1050 FOR DETAILEDREQUIREMENTS FOR VERIFICATION AND DOCUMENTATION OF INTERMEDIATE COVER PREPARATION.

5. ACREAGE NOTED ON DRAWING IS BASED ON PLANAR VIEW OF SITE. CONTRACTOR TO COMPUTE SLOPE SURFACE AND WASTE MATERIALS QUANTITIES ON BID FORM.

6. CONTRACTOR TO EXPOSE EDGE OF EXISTING LINER TO WHICH THE CAP LINER WILL BE WELDED. FINAL COVER OVER THE LINER WILL EXTEND BEYOND THESE POINTS.

7. INTERMEDIATE COVER ELEVATIONS SHOWN AT TOE OF SLOPE ARE TO INDICATE GENERAL BOTTOMLINER ELEVATIONS AND MAY NOT REFLECT ACTUAL ELEVATIONS.
