LEGEND NOTES

1. NO GUARANTEE IS INTENDED THAT UNDERGROUND

OBSTRUCTIONS NOT SHOWN ON THE PLANS WILL NOT BE

ENCOUNTERED. LOCATION OF EXISTING UNDERGROUND

UTILITIES OR OBSTRUCTIONS AS SHOWN ON THESE PLANS IS

BASED UPON THE BEST INFORMATION AVAILABLE, HOWEVER,

THE NPS AND THE ENGINEER ASSUME NO RESPONSIBILITY

FOR THE ACCURACY OF THE INFORMATION SHOWN OR THE

INADVERTENT OMISSION OF ANY SUCH INFORMATION.

2. PROTECT ALL UTILITIES DURING EXCAVATION AND THOSE

UTILITIES ADJACENT TO THE EXCAVATION UNLESS

OTHERWISE SPECIFIED ON PLANS. ANY UTILITIES THAT ARE

BROKEN OR DAMAGED DURING CONSTRUCTION SHALL BE

REPAIRED AT THE CONTRACTOR'S EXPENSE.

3. SITE PREPARATION INCLUDES REMOVING ALL VEGETATION

AND OVER-SIZE DEBRIS FROM THE AREAS THAT WILL BE

GRADED. AT LOCATIONS WHERE TREES AND STUMPS HAVE

BEEN REMOVED, REMOVE ALL ROOTS LARGER THAN 2

INCHES IN DIAMETER, CHIP AND MULCH ON-SITE FOR USE AS

TOP DRESSING OF DISTURBED AREAS.

4. PRIOR TO PLACING ANY FILLS, THE SUBGRADE SURFACE

SHOULD BE SCARIFIED TO A DEPTH OF 8-INCHES; MOISTURE

CONDITIONED TO ABOVE THE OPTIMUM MOISTURE CONTENT

AND COMPACTED TO A MINIMUM OF 90 PERCENT RELATIVE

COMPACTION (ASTM D-1557). WHERE MATERIALS CANNOT BE

TESTED PER ASHTO D-1557, COMPACT TO PROVIDE FIRM,

UNYIELDING SURFACE.

5. FOR CUT AND FILL EARTH SLOPE CONSTRUCTION, THE

MAXIMUM INCLINATION OF SLOPES SHOULD BE 2:1

(HORIZONTAL TO VERTICAL). THE MAXIMUM INCLINATION OF

ROCK SLOPES SHALL BE 1:1.

6. THE CONTRACTOR IS SOLELY RESPONSIBLE FOR ALL

EXCAVATION AND EARTHWORK RELATED ACTIVITIES

ASSOCIATED WITH THIS PROJECT. ALL EXCAVATION WORK

MUST CONFORM TO THE EXCAVATION SAFETY

REQUIREMENTS SET FORTH BY OSHA 1926 SUBPART P.

7. PROTECT THE PUBLIC FROM OPEN EXCAVATIONS AND

TRENCHES. AT NO TIME SHALL AN EXCAVATION OR TRENCH

BE UNATTENDED WITHOUT PROPER PLATING OR SAFETY

FENCING BARRICADES IN PLACE. AT THE END OF THE WORK

DAY, INSPECT ALL EXCAVATION AND TRENCH PLATING AND

SAFETY FENCING / BARRICADES TO ENSURE THEY ARE

PROPERLY FUNCTIONING.

8. EXCAVATED MATERIALS SHALL BE GRADED, HAULED,

STOCK-PILED AND PROTECTED IF CONTRACTING OFFICER'S

REPRESENTATIVE DEEMS SUITABLE FOR BACKFILLING, OR

OTHER PURPOSES. MATERIAL DEEMED UNSUITABLE SHALL

BE DISPOSED OF BY THE CONTRACTOR.

9. CONTRACTOR MAY TEMPORARILY STOCK-PILE SOIL ON SITE

THAT IS UNSUITABLE FOR BACKFILL MATERIAL FOR FUTURE

DISPOSAL AT AN APPROVED OFF SITE LOCATION PRIOR TO

THE END OF THE PROJECT. STORAGE OF SOIL ON SITE

SHALL BE DONE IN A NEAT AND ORDERLY MANNER WITH ALL

NECESSARY EROSION CONTROL MEASURES IN PLACE.

10. GRADING SHALL BE REVIEWED IN FIELD AND APPROVED BY

CONTRACTING OFFICER'S REPRESENTATIVE.
