CALL MISS UTILITY AT 811 OR 18005527001 BEFORE DIGGING. EACH "PERSON" AS DEFINED IN THE UNDERGROUND UTILITY DAMAGE PREVENTION ACT MUST PROVIDE THEIR OWN NOTICE OF EXCAVATION. SUBCONTRACTORS MAY NOT WORK UNDER ANOTHER COMPANY'S TICKET UNLESS THEY ARE UNDER THE DIRECT SUPERVISION OF THE COMPANY THAT PROVIDED THE NOTICE OF EXCAVATION. ALLOW REQUIRED TIME FOR MARKING - BEGIN EXCAVATION ONLY AFTER CHECKING THE POSITIVE RESPONSE SYSTEM, EXCAVATION MAY BEGIN WHEN: ALL NOTIFIED UTILITIES HAVE EITHER MARKED THEIR LINES OR REPORTED THAT THEY HAVE NO FACILITIES IN THE AREA OF EXCAVATION OR THE MARKING PERIOD HAS EXPIRED (AFTER 7:00 AM ON THE THIRD WORKING DAY AFTER NOTICE TO THE CENTER.) OR MISS UTILITY INFORMS YOU THAT NO MEMBER OPERATORS NEED TO BE NOTIFIED OF THE EXCAVATION. YOU WILL STILL GET A TICKET NUMBER! RESPECT THE MARKS - PROTECT AND PRESERVE THE MARKINGS FROM THE TIME EXCAVATION BEGINS UNTIL THE WORK IS COMPLETED. CALL MISS UTILITY TO UPDATE THE TICKET IF WORK WILL CONTINUE PAST 15 DAYS OR IF THE MARKS BECOME ILLEGIBLE DUE TO TIME, WEATHER, CONSTRUCTION OR ANY OTHER CAUSE, EXCAVATE CAREFULLY - IF THE EXCAVATION IS WITHIN 2 FEET OF A MARKED UTILITY LINE, EXPOSE THE UTILITY LINE BY HAND DIGGING AND KEEP ALL MECHANIZED EQUIPMENT AT LEAST 2 FEET AWAY FROM THE EXTREMITIES OF THE UTILITY. ALBEMARLE COUNTY GENERAL CONSTRUCTION NOTES 1. PRIOR TO ANY CONSTRUCTION WITHIN ANY EXISTING PUBLIC RIGHT-OF-WAY, INCLUDING CONNECTION TO ANY EXISTING ROAD, A PERMIT SHALL BE OBTAINED FROM THE VIRGINIA DEPARTMENT OF TRANSPORTATION (VDOT).

ALL SLOPES AND DISTURBED AREAS ARE TO BE FERTILIZED, SEEDED AND MULCHED. 6. THE MAXIMUM ALLOWABLE SLOPE IS 2: 1 (HORIZONTAL: VERTICAL). WHERE REASONABLY OBTAINABLE, LESSER SLOPES OF 3:1 OR BETTER ARE TO BE ACHIEVED, 7.

MINERAL ADMIXTURES SHALL CONFORM TO ASTM C618 EXCEPT THAT LOSS ON IGNITION SHALL BE 3.5% OR LESS. 8. ALL OTHER MATERIALS USED IN THE CONCRETE SHALL CONFORM TO CURRENT APPLICABLE ASTM SPECIFICATIONS. 9. CONCRETE SHALL BE MANUFACTURED AND DELIVERED IN ACCORDANCE WITH THE LATEST REVISED STANDARD SPECIFICATION FOR READY MIXED CONCRETE, ASTM C94. CONCRETE SHALL HAVE A MINIMUM 28-DAY COMPRESSIVE STRENGTH OF 4500 PSI AND CONTAIN A TOTAL AIR CONTENT OF 6% PLUS OR MINUS 1 1/2 BY VOLUME. CONCRETE SLUMP SHALL BE:1 - 4 INCHES IF PLACEMENT AND CONSOLIDATION IS BY MECHANICAL METHOD SUCH AS VIBRATORY SCREED; OR 1 -5 INCHES IF PLACEMENT AND CONSOLIDATION IS BY OTHER MEANS, UNLESS A SUPER PLASTICIZER IS USED IN ACCORDANCE WITH THE MANUFACTURER'S RECOMMENDATIONS. 10. FOR LIGHT VEHICULAR PARKING AREAS AND DRIVEWAYS, A 4" MINIMUM PAVEMENT THICKNESS IS REQUIRED. 11. FOR LIGHT TRUCK TRAFFIC LANES, A 5" MINIMUM PAVEMENT THICKNESS IS REQUIRED. 12. THE BOTTOM OF THE EXCAVATION OR THE TOP OF THE FILL SHALL BE KNOWN AS THE PAVEMENT SUBGRADE AND SHALL CONFORM TO THE LINES, GRADE, AND CROSS SECTIONS SHOWN IN THE PLANS. IN MOST SITUATIONS WITH MOST SOILS, SIMPLE REMOVAL OF TOPSOIL AND EXCAVATION DOWN TO THE DESIRED PAVEMENT SUBGRADE IS SUFFICIENT PREPARATION FOR THE DIRECT APPLICATION OF CONCRETE PAVEMENT. 13. IN SITUATIONS WHERE THE SUBGRADE CONTAINS SECTIONS OF SOFT AND YIELDING SOIL, SUCH SOIL MUST BE REMOVED. IT MUST BE REPLACED WITH A MATERIAL (OR SOIL) THAT WILL, AFTER COMPACTION, BRING THE SUBGRADE TO A FIRM, UNYIELDING; AND UNIFORMLY DENSE CONDITION. (IF SOIL IS USED AS A REPLACEMENT MATERIAL, IT SHOULD BE COMPACTED AT OR SLIGHTLY ABOVE OPTIMUM MOISTURE.) 14. BEFORE PLACING CONCRETE, FREESTANDING WATER, SNOW, ICE, OR OTHER FOREIGN MATERIALS SHALL BE REMOVED FROM SUBGRADE. ALL FORMS SHALL BE THOROUGHLY CLEANED, SECURED IN POSITION, AND COATED WITH A FORM RELEASE AGENT. 15. CONCRETE SHALL NOT BE PLACED ON A SOFT, SPONGY, FROZEN, OR OTHERWISE UNSUITABLE SUBGRADE. THE SUBGRADE SHALL BE DAMP WHEN CONCRETE IS PLACED. 16. CONCRETE SHALL BE PLACED, STRUCK OFF, AND CONSOLIDATED TO PLAN GRADE WITH A MECHANICAL PLACEMENT MACHINE, VIBRATING SCREED, OR BY HAND FINISHING METHODS WHEN APPROVED. IN LIEU OF FIXED FORMS, THE CONTRACTOR MAY PLACE CONCRETE WITH A SLIPFORM PAVER DESIGNED TO SPREAD, CONSOLIDATE, SCREED, AND FLOAT FINISH THE FRESHLY PLACED CONCRETE IN ONE COMPLETE PASS OF THE MACHINE. PAVEMENT SHALL BE PITCHED TO AREA DRAINS OR PERIMETER AREAS TO REMOVE WATER. 17. NO REINFORCEMENT IS REQUIRED. 18. AFTER CONCRETE HAS BEEN STRUCK OFF AND CONSOLIDATED, A BULLFLOAT MAY BE USED TO REMOVE ANY HIGH OR LOW SPOTS. BULLFLOAT USE SHALL BE CONFINED TO A MINIMUM. MECHANICAL FINISHING MACHINE FLOATING IS ACCEPTABLE; HOWEVER, UNDER NO CIRCUMSTANCES SHALL THE CONCRETE SURFACE BE STEEL TROWELED. A FINAL SKID RESISTANT FINISH SHALL BE MADE WITH A BURLAP DRAG OR BROOM. 19. CONCRETE MUST BE CURED BY PROTECTING IT FROM LOSS OF MOISTURE, RAPID TEMPERATURE CHANGE AND MECHANICAL INJURY ACCORDING TO THE LATEST EDITION OF ACI 301. USE MEMBRANE -FORMING CURING COMPOUND APPLIED TO ALL SURFACES AT MAXIMUM RATE OF 200 FT2/GAL TO CURE. 20. WHEN CONCRETE IS BEING PLACED IN COLD WEATHER AND THE TEMPERATURE MAY DROP BELOW 35•F., STRAW, HAY, INSULATED CURING BLANKETS, OR OTHER SUITABLE MATERIAL SHALL BE PROVIDED ALONG THE LINE OF WORK TO PREVENT FREEZING OF CONCRETE. CONCRETE INJURED BY FROST ACTION SHALL BE REMOVED AND REPLACED AT THE CONTRACTOR'S EXPENSE. 21. UNLESS SHOWN ON THE PROJECT DRAWINGS, A JOINING PLAN SHALL BE PREPARED BY THE CONTRACTOR AND APPROVED BEFORE PAVING BEGINS. 22. TYPICAL DRYING SHRINKAGE CRACKING MUST BE MINIMIZED AND CONTROLLED BY PROPER JOINTING. TO MINIMIZE AND CONTROL CRACKING, JOINTS SHALL BE: A) CONTINUOUS ACROSS THE SLAB; B) SYMMETRICAL (IN SQUARES OR RECTANGLES WHERE POSSIBLE); C) SPACED AT NO MORE THAN 2 1/2 TIMES IN FEET THE SLAB THICKNESS IN INCHES (15 FT MAX SPACING). 23. ISOLATION JOINTS (EXPANSION JOINTS) SHALL BE USED TO ISOLATE FIXED OBJECTS ABUTTING OR WITHIN THE PAVED AREA. THEY SHALL CONTAIN PREMOLDED JOINT FILLER FOR THE FULL DEPTH OF THE SLAB. 24, CONTROL JOINTS (CONTRACTION JOINTS) SHOULD BE PRODUCED BY SAWING. JOINT DEPTH SHALL BE A MINIMUM OF ONE-FOURTH THE SLAB THICKNESS. HAND -TOOLED JOINTS SHALL HAVE A MAXIMUM EDGE RADIUS OF 1/4 INCH. SAWING OF JOINTS SHALL BEGIN AS SOON AS THE CONCRETE HAS HARDENED SUFFICIENTLY TO PERMIT SAWING WITHOUT EXCESSIVE RAVELING. ALL JOINTS SHALL BE COMPLETED BEFORE UNCONTROLLED SHRINKAGE CRACKING OCCURS. 25. CONSTRUCTION JOINTS (JOINTS ENDING A DAY'S POUR) MUST ALLOW WHEEL LOAD TRANSFER ACROSS THE JOINTS WHERE NECESSARY. IN SUCH CASES, THESE JOINTS SHALL BE THICKENED EDGE BUTT JOINTS. 26. JOINTS SHALL EXTEND COMPLETELY THROUGH THE CURB WHEN THE CURB IS INTEGRALLY FORMED WITH THE SLAB. 27.

ED Ponds are prone to a high clogging risk at the ED low -flow orifice. Ideally, the orifice should be inspected at least twice a year after initial construction. The constantly changing water levels in ED Ponds make it difficult to mow or manage vegetative growth. The bottom of ED Ponds often become soggy, and water -loving tees such as willows may invade and will need to be managed. Periodic mowing of the stormwater buffer is only required along maintenance rights -of -way and the embankment. The remaining buffer may be managed as a meadow (mowing every other year) or forest. Frequent removal of sediment from the forebay (every 5-7 years, or when 50% of the forebay capacity is filled) is essential to maintain the function and performance of the ED Pond. Sediments excavated from ED Ponds are usually not considered toxic or hazardous, so they can be safely disposed of either by land application of land filling.
