NO FURTHER EXCAVATION OR DISTURBANCE OF THE DISCOVERY OR ANY NEARBY AREA REASONABLY SUSPECTED TO OVERLIE ADJACENT REMAINS, AS DETERMINED BY A QUALIFIED ARCHAEOLOGIST AND/OR A TRADITIONALLY AND CULTURALLY AFFILIATED (TCA) NATIVE AMERICAN MONITOR, SHALL OCCUR UNTIL THE CORONER HAS MADE THE NECESSARY FINDINGS AS TO ORIGIN AND DISPOSITION PURSUANT TO PUBLIC RESOURCES CODE 5097.98. IF SUCH A DISCOVERY OCCURS, A TEMPORARY CONSTRUCTION EXCLUSION ZONE SHALL BE ESTABLISHED SURROUNDING THE AREA OF THE DISCOVERY SO THAT THE AREA WOULD BE PROTECTED (AS DETERMINED BY THE QUALIFIED ARCHAEOLOGIST AND/OR THE TCA NATIVE AMERICAN MONITOR), AND CONSULTATION AND TREATMENT COULD OCCUR AS PRESCRIBED BY LAW. AS FURTHER DEFINED BY STATE LAW, THE CORONER WOULD DETERMINE WITHIN TWO WORKING DAYS OF BEING NOTIFIED IF THE REMAINS ARE SUBJECT TO HIS OR HER AUTHORITY. IF THE CORONER RECOGNIZES THE REMAINS TO BE NATIVE AMERICAN, HE OR SHE SHALL CONTACT THE NATIVE AMERICAN HERITAGE COMMISSION (NAHC) WITHIN 24 HOURS. THE NAHC WOULD MAKE A DETERMINATION AS TO THE MOST LIKELY DESCENDENT. IF NATIVE AMERICAN REMAINS ARE DISCOVERED, THE REMAINS SHALL BE KEPT INSITU(IN PLACE"), OR IN A SECURE LOCATION IN CLOSE PROXIMITY TO WHERE THEY WERE FOUND, AND THE ANALYSIS OF THE REMAINS SHALL ONLY OCCUR ON -SITE IN THE PRESENCE OF THE TCA NATIVE AMERICAN MONITOR.

DUMPSTERS WITHOUT LIDS SHALL BE PLACED WITHIN STRUCTURES WITH IMPERVIOUS ROOFING OR COVERED WITH TARPS IN ORDER TO AVOID RAIN CONTACT WITH ANY TRASH MATERIAL. MANY CONSTRUCTION MATERIALS, INCLUDING SOLVENTS, WATER -BASED PAINTS, VEHICLE FLUIDS, BROKEN ASPHALT AND CONCRETE, WOOD, AND CLEARED VEGETATION CAN BE RECYCLED. NON -RECYCLABLE MATERIALS MUST BE TAKEN TO AN APPROPRIATE LANDFILL OR DISPOSED OF AS HAZARDOUS WASTE. FOR INFORMATION ON DISPOSAL OF HAZARDOUS MATERIAL, CALL THE HAZARDOUS WASTE HOTLINE TOLL FREE AT (800) 714-1195, FOR INFORMATION ON LANDFILLS AND TO ORDER DUMPSTERS CALL EDCO AT (760) 436-4151. POLLUTANTS SHALL BE KEPT OFF EXPOSED SURFACES. PLACE TRASH CANS AND RECYCLING RECEPTACLES AROUND THE SITE. PORTABLE TOILETS MUST BE IN GOOD WORKING ORDER AND CHECKED FREQUENTLY FOR LEAKS. CONTRACTOR SHALL PROVIDE SECONDARY CONTAINMENT AND LOCATE PORTABLE TOILETS AWAY FROM STORMDRAIN INLETS ON PERVIOUS SURFACES. ALL CONSTRUCTION DEBRIS SHALL BE KEPT AWAY FROM THE STREET, GUTTER, AND STORMDRAIN. CONTRACTOR MUST ROUTINELY CHECK AND CLEAN UP MATERIAL THAT MAY HAVE TRAVELED AWAY FROM CONSTRUCTION SITE FOR MORE INFORMATION ON STORMWATER POLLUTION CONTROL MEASURES AND REQUIREMENTS PLEASE CONTACT THE ENGINEERING DEPARTMENT, CITY OF ENCINITAS AT (760) 633-2770. STORMWATER POLLUTION CONTROL POST CONSTRUCTION BMP/IMP NOTES 1. FOR STORM WATER POLLUTION CONTROL PURPOSES, ALL RUNOFF FROM ALL IMPERVIOUS SURFACES INCLUDING ROOF DRAINS SHALL DISCHARGE ONTO GRASS AND LANDSCAPE AREAS PRIOR TO COLLECTION AND DISCHARGE ONTO THE STREET AND/OR INTO THE PUBLIC STORM DRAIN SYSTEM. 2. GRASS AND LANDSCAPE AREAS DESIGNATED FOR STORM WATER POLLUTION CONTROL SHALL NOT BE MODIFIED WITHOUT A PERMIT FROM THE CITY. 3. ALL IMPERVIOUS AREAS WITHIN THE SITE SHALL DRAIN TO APPROVED BMP/IMP FACILITIES AND/OR TO TURF OR LANDSCAPED AREAS WITH ADEQUATE GROUNDCOVER PRIOR TO DISCHARGE FROM THE SITE. ALL IMPERVIOUS AREAS MUST SLOPE TOWARD THE APPROVED BMP/IMP FACILITY AND/OR THE TURF/LANDSCAPED AREAS. 4. NO DRAINS SHALL BE INSTALLED IN HARDSCAPE, DRIVEWAYS, OR ANY OTHER IMPERVIOUS AREA UNLESS THE FLOW FROM THE DRAIN DISCHARGES TO AN ADEQUATE IMP/BMP. 5. DRIVEWAYS SHALL HAVE A MINIMUM 2% CROSS SLOPE TOWARD THE IMP/BMP AREA OR HAVE ANOTHER APPROVED DRAINAGE SYSTEM THAT IS DESIGNED TO COLLECT RUNOFF AND DISCHARGE IT TO AN ADEQUATE IMP/BMP. 6. ALL STORMWATER IMP/BMP FACILITIES SHOWN HEREON SHALL NOT BE MODIFIED OR ALTERED WITHOUT A PERMIT FROM THE CITY. 7. THE INSTALLATION OF ADDITIONAL IMPERVIOUS SURFACES NOT SHOWN ON THIS PLAN MAY REQUIRE THAT THIS PLAN BE REVISED OR THAT A SEPARATE ENGINEERING PERMIT BE OBTAINED. 8. ALL EXISTING AND PROPOSED TRASH ENCLOSURES SHALL BE FITTED TO COMPLY WITH STORM WATER BEST MANAGEMENT PRACTICE REQUIREMENTS. THE TRASH ENCLOSURES SHALL HAVE AN IMPERVIOUS, NON-COMBUSTIBLE ROOF THAT WILL NOT ALLOW RAIN WATER TO ENTER THE ENCLOSURE, THE ENCLOSURE SHALL BE LOCKABLE AND LOCKED WHEN NOT IN USE. A BERM SHALL BE INSTALLED AT ALL OPENINGS TO HOLD IN ANY LIQUIDS THAT ESCAPE FROM THE DUMPSTER AND TO PREVENT ANY FLOW OF STORM WATER THROUGH THE TRASH ENCLOSURE AREA. THE BERM CAN BE CONSTRUCTED WIDE AND FLAT TO ALLOW ROLLING OF THE DUMPSTER IN AND OUT. THE ENCLOSURE SHALL BE SELF CONTAINED OR MAY HAVE A DRAIN THAT DISCHARGES THROUGH AN ADEQUATELY SIZED OIL/ GREASE SEPARATOR AND IS THEN FILTERED THROUGH A CITY -APPROVED HYDROCARBON FILTER AND DISCHARGED INTO THE PUBLIC SANITARY SEWER SYSTEM, NOT TO PLANTERS OR THE STORM DRAIN SYSTEM. A SEPARATE BUILDING PERMIT MAY BE REQUIRED FOR THIS STRUCTURE.

BACKFILL SHALL BE LEVEL SUCH THAT ANY SHALLOW DEPRESSIONS AND HUMPS DO NOT EXCEED 6" IN DEPTH OR HEIGHT. BACKFILL SHALL BE PLACED, SPREAD AND COMPACTED IN SUCH A MANNER TO MINIMIZE THE DEVELOPMENT OF SLACK OR LOSS OF PRE -TENSION OF THE GSR. TRACKED CONSTRUCTION EQUIPMENT SHALL NOT BE OPERATED DIRECTLY ON THE GSR. A MINIMUM UNCOMPACTED BACKFILL THICKNESS OF 6" IS REQUIRED PRIOR TO OPERATION OF TRACKED VEHICLES OVER THE GSR. TURNING OF TRACKED VEHICLES SHALL BE KEPT TO A MINIMUM TO PREVENT TRACKS FROM DISPLACING THE FILL AND DAMAGING THE GSR. RUBBER -TIRED EQUIPMENT MAY PASS OVER GSR REINFORCEMENT AT SLOW SPEEDS, LESS THAN 10 MPH. AVOID SUDDEN BRAKING AND SHARP TURNING. 20.A.

EXP.: 6/30/20 STRUCTURAL REVIEW PERFORMED BY ESGIL, A SAFEBUILT COMPANY AS PLANCHECK 19-611 DATED MARCH 26, 2019 THE AREA BEHIND THE WALL CONTAINS GEOGRID REINFORCING MATERIAL (REINFORCED ZONE) THAT IS THE STRUCTURAL COMPONENT OF THE WALL SYSTEM. UNDER NO CIRCUMSTANCES ARE YOU TO EXCAVATE OR DRILL THROUGH, OR DAMAGE THE FABRIC IN ANY WAY. IF IT BECOMES NECESSARY TO DO SO, PLEASE CONSULT YOUR CIVIL AND/OR DESIGN ENGINEER TO EVALUATE THE STRUCTURAL IMPACT. THERE IS A SUB -DRAIN LINE AT THE BASE OF THE WALL. IT WILL BE STUBBED OUT FOR FINAL CONNECTION BY OTHERS. TO INSURE PROPER DRAINAGE, ENSURE THAT ALL CONNECTIONS ARE MADE IMMEDIATELY AFTER THE COMPLETION OF THE WALL. NO STANDING WATER SHOULD BE LEFT TO ACCUMULATE OR LEACH INTO THE REINFORCED ZONE ABOVE THE WALL. PADS OR SLOPES ABOVE THE WALL ARE TO DRAIN AWAY FROM THE WALL AND ANY REQUIRED 'V' DITCHES INSTALLED IMMEDIATELY AFTER WALL INSTALLATION IS COMPLETE. NO STANDING OR RUNNING WATER SHOULD BE ALLOWED TO FLOW NEAR THE SLOPE ADJACENT TO THE GRAVEL BASE.(BOTTOM) ANY KNOWN SUBTERRANEAN WATER SHOULD BE INTERCEPTED AND DIVERTED AWAY FROM REINFORCED ZONE AND BASE. ANY 'V' DITCH ABOVE THE WALL SHOULD BE DESIGNED OF SUFFICIENT SIZE TO REMOVE ALL SURFACE WATER AND AVOID THE FLOW OF WATER OVER THE TOP OF THE WALL. OVERFLOW CAN CAUSE EROSION AT THE BASE OF THE WALL THAT MAY UNDERMINE IT. ANY LANDSCAPE WATERING AND ADDITIONAL SURFACE DRAINAGE IN THE REINFORCED ZONE SHOULD BE DESIGNED IN CONJUNCTION WITH THE GEOTECHNICAL ENGINEER AND LIMIT WATER FROM PERCOLATING INTO THE REINFORCED ZONE, THIS SEGMENTAL WALL BLOCK IS CONSTRUCTED OVER A GRAVEL BASE. ALL SURFACE WATER RUN-OFF OR SLOPES MUST BE DIVERTED AWAY FROM THE BASE OF WALL TO PREVENT PONDING AND UNDERMINING THE BASE. ALL UTILITY LINE AND SANITARY CONSTRUCTION SHOULD BE AVOIDED WITHIN THE REINFORCED ZONE. ANY LINES CONSTRUCTED BEHIND THE GRID ZONE SHOULD BE COMPACTED TO 90%+. DO NOT OPERATE HEAVY EQUIPMENT WITHIN 3 FEET FROM THE TOP OF WALL. THE SURCHARGE FROM THE EQUIPMENT WEIGHT CAN PUSH THE WALL OUT, ANY REPAIRS ARE THE RESPONSIBILITY OF THE OWNER. ALL COMPACTED FILL MATERIAL WILL SETTLE OR CONSOLIDATE OVER TIME. SEGMENTAL WALLS REQUIRE COMPACTED FILL MATERIAL. ALL FOUNDATIONAL MATERIALS BELOW THE BLOCK AND GRID ZONE MUST BE TESTED PRIOR TO WALL CONSTRUCTION TO ENSURE PRIOR CONSOLIDATION AND COMPACTION OF THE FOUNDATIONAL MATERIALS. THERE IS AN ALLOWABLE VARIANCE OF +/- 6" IN THE WALL FACE DURING INSTALLATION AND THE SETTLEMENT PERIOD. SEGMENTAL RETAINING WALLS ARE FLEXIBLE (NOT RIGID AS ARE CMU WALLS). ALL STRUCTURES SUCH AS TRASH ENCLOSURES, PAVEMENT, CURBS, ETC., SHOULD BE DESIGNED TO HANDLE SOME GROUND MOVEMENT IF THEY ARE NEAR THE WALL, PLEASE CONSULT YOUR DESIGN ENGINEER FOR FURTHER DETAILS. PRIOR TO CONSTRUCTION A HARD COPY SHALL BE SIGNED AND LEFT WITH THE ONSITE HILLSIDE COMPANIES REPRESENTATIVE.
