GENERAL NOTES:

1. Cut all brush within treatment area which is less than or equal to 6 inches in diameter measured 6 inches above the ground.

2. For Method A, cut brush back 5 feet slope distance beyond bottom of ditch or 15 feet slope distance from road shoulder, whichever is less, & 10 feet slope distance beyond the edge of the road shoulder on the fill slope.

3. For Method B, cuall all brush within 5 feet of culvert inlets

4. Cut brush to provide overhead clearance of 14 feet on the road surface.

5. Remove debris from the road surface, ditches & cut slope above the road. Scatter to fill slopes below the road, no debris piles allowed at culvert outlets.

6. Clear ditches of woody debris. Clean culvert inlets & outlets of debris a minimum of 2 culvert diameters.

7. Cut brush to provide sufficient sit distance on the inside of sharp curves to eliminate blind corners and intersections.

PLACING THE ADDITIONAL XXXX WIDTH OF

AGGREGATE IN TURNOUT AREAS AND SECTIONS

REQUIRING CURVE WIDENING, PLACE ADJACENT

TO CENTERLINE LIFT AND COMPACT TOGETHER.

NOTE: OUTSLOPED ROADS SHOULD BE USED

WHEN ROAD GRADES ARE GENTLE TO MODERATE

(0% TO 8%) AND WHERE CUTSLOPES ARE DRY.

OUTSLOPED ROADS SHOULD BE CONSTRUCTED

WITH ROLLING DIPS FOR DRAINAGE. THERE

SHOULD BE NO DITCH ON THE INBOARD SIDE OF

THE OUTSLOPED ROAD.

NOTE: INSLOPED ROADS SHOULD BE USED WHEN

ROAD GRADES ARE MODERATE TO STEEP (6%

AND UP) AND WHERE TERRAIN MAY BE STEEP OR

SLIPPERY. INSLOPED ROADS ARE ALSO IDEAL

FOR HIGHLY ERODIBLE AREAS. EXTRA

ATTENTION SHOULD BE PAID TO ESTABLISHING

DITCHES AND DRAINAGE FOR INSLOPED ROADS.

NOTES

1. ALL PITS AND QUARRIES SHALL BE APPROVED IN WRITING BY THE CO PRIOR TO

EXPLORATION, CLEARING OR DEVELOPMENT.

2. REMOVE ALL OVERBURDEN TO SOLID ROCK FOR A MINIMUM DISTANCE OF 15' FROM

THE WORKING FACE.

3. SLOPE THE CUT BANK OF THE OVERBURDEN TO THE NATURAL ANGLE OF REPOSE BUT

IN NO CASE STEEPER THAN 1:1.

4. WITHIN THE CLEARING LIMITS:

4.1. MAXIMUM STUMP HEIGHT SHALL BE IN ACCORDANCE WITH SPECIFICATIONS.

4.2. STABLE TREES UP TO 6" (DBH) NEED NOT BE CUT IF THEY WILL NOT INTERFERE

WITH BACK SLOPE STABILITY.

4.3. STUMPS AND BRUSH MAY BE LEFT IN PLACE, EXCEPT THAT ALL STUMPS THAT

PROTRUDE FROM EXCAVATED BANKS OR THAT HAVE THE POTENTIAL TO BECOME

DISLODGED AT ANY LATER DATE SHALL BE REMOVED.

5. DISPOSE OF OR STOCKPILE FOR LATER USE ALL OVERBURDEN, CLEARING,

MERCHANTABLE TIMBER AND GRUBBING DEBRIS AS SHOWN ON THE QUARRY

DEVELOPMENT PLAN.

6. FELL ALL DEAD TREES AND SNAGS WHICH ARE SUFFICIENTLY TALL TO REACH THE

WORK AREA.

7. LEAVE THE PIT/QUARRY IN A NEAT, ORDERLY AND WELL-DRAINED CONDITION.

REMOVE ALL OVERHANGS AND LOOSE ROCK.

8. AFTER EXCAVATION IS COMPLETE CLEAN THE AREA AND LEAVE AS SHOWN ON THE

QUARRY DEVELOPMENT PLAN. TREAT ANY ACCESS ROAD AS SHOWN ON THE QUARRY

DEVELOPMENT PLAN.

9. TEST SHOTS OF 1300 TO 2600 CY ARE REQUIRED AT ALL QUARRY SITES IF DESCRIBED

IN THE SPECIFICATIONS.

10. LEAVE NO MORE THAN 5% BY VOLUME OF OVERSIZE MATERIAL IN THE QUARRY.

BREAK DOWN ANY MATERIAL OVER THIS VOLUME AND USE AS SPECIFIED IN SECTIONS

651.

11. PROVISIONS FOR FUTURE QUARRY DEVELOPMENT ACCESS WILL BE PROVIDED,

UNLESS THIS REQUIREMENT IS WAVED BY THE CO.

12. INSTALL AND MAINTAIN A COMMERCIALLY AVAILABLE RAIN GAUGE MEASURING IN

UNITS OF INCHES AND FRACTIONS OF INCHES IN ACCORDANCE WITH SECTION 205.08.

13. HAUL WILL NOT BE ALLOWED BEYOND DESIGNATED SOURCES UNLESS OTHERWISE

SHOWN ON THE DRAWINGS OR AGREED TO BY THE CO.

14. SEED AND FERTILIZE ALL DISTURBED AREAS SUCH AS OVERBURDEN PILES AND BENCH
