EARTHWORK NOTES
1. GENERAL: EARTHWORK SHALL INCLUDE THE LOOSENING AND REMOVAL, TRANSPORTING, STORAGE, BACKFILLING, GRADING
AND ALL HANDLING OF NATURAL SOIL, DEPOSITED SOILS, OR ROCK FOR CONSTRUCTION OF ALL WORK UNDER THIS
CONTRACT.
2. STRIPPING AND STOCKPILING OF TOPSOIL: STRIP ALL TOPSOIL TO ITS ENTIRE DEPTH IN THE AREAS TO BE GRADED AND
PILE IN APPROVED OR DESIGNATED AREAS BEFORE ANY GRADING OR FILLING IS BEGUN. SOIL SHALL BE FREE FROM
CLAY, LARGE STONES AND DEBRIS. THIS TOPSOIL SHALL BE USED FOR FINAL FINISH GRADING.
3. EXCAVATION FOR STRUCTURES: CONFORM TO ELEVATIONS AND DIMENSIONS SHOWN WITHIN A TOLERANCE OF PLUS OR
MINUS 0.10'.

MATERIALS ENCOUNTERED THAT EXTEND BELOW REQUIRED ELEVATIONS TO DEPTH DIRECTED BY THE SOILS ENGINEER.
LATERAL DIMENSIONS, DEPTH AND VOLUME SHALL BE DETERMINED BY SOILS ENGINEER. PAYMENT SHALL NOT BE MADE
FOR MATERIALS REMOVED IF THE SOILS ENGINEER IS NOT PRESENT AT THE TIME OF REMOVAL.
5. ROCK EXCAVATION: WHERE EXPLOSIVES ARE USED, WORK SHALL BE DONE BY EXPERIENCED POWDERMEN USING SMALL
CHARGES IN STRICT ACCORDANCE WITH ALL REGULATIONS GOVERNING THIS WORK. BLASTING WILL NOT BE PERMITTED
WITHOUT SPECIAL AUTHORIZATION OF THE OWNER, THE ENGINEER, AND LOCAL AUTHORITIES. THE CONTRACTOR SHALL BE

GRADING NOTES
1. THE UTILITIES AND THE LOCATIONS THEREOF, SHOWN ON THE PLANS, REPRESENT THE DESIGNER'S
UNDERSTANDING OF EXISTING UTILITIES IN THE CONSTRUCTION AREA. THE CONTRACTOR SHALL VERIFY
THE LOCATION DEPTH AND EXISTENCE OF ALL UTILITIES ELECTRICAL MECHANICAL GAS WATER
TELEPHONE, ETC.) WITHIN THE CONSTRUCTION AREA WITH THE OWNER AND/OR THE APPROPRIATE UTILITY
COMPANY PRIOR TO BEGINNING ANY EXCAVATION. THE OMISSION OR THE INCLUSION OF UTILITY
LOCATIONS ON THE PLANS IS NOT TO BE CONSIDERED AS THE NON-EXISTENCE OF OR A DEFINITE

MUST BE MATTED OR BENCHED. FILL SLOPES GREATER THAN 10' REQUIRE ADEQUATE TERRACING.
8. GRADING MORE THAN ONE (1) ACRE WITHOUT AN APPROVED EROSION CONTROL PLAN IS A VIOLATION
OF THE CITY/COUNTY EROSION CONTROL ORDINANCE AND IS SUBJECT TO FINES.
9. ANY GRADING BEYOND THE LIMITS OF DISTURBANCE SHOWN IS A VIOLATION OF THE CITY/COUNTY
EROSION CONTROL ORDINANCE AND IS SUBJECT TO FINES.
10. APPROVAL OF THIS PLAN IS NOT AN AUTHORIZATION TO GRADE ADJACENT PROPERTIES. WHEN FIELD
CONDITIONS WARRANT OFF -SITE GRADING, PERMISSION SHALL BE OBTAINED FROM THE AFFECTED
PROPERTY OWNER'S).
11. ANY LAND DISTURBING ACTIVITY GREATER THAN FIVE (5) ACRES REQUIRES COMPLIANCE WITH ALL
CONDITIONS OF THE GENERAL PERMIT TO DISCHARGE STORM WATER UNDER THE NATIONAL POLLUTANT
DISCHARGE ELIMINATION SYSTEM (PERMIT NO. NCG010000). ANY PERMIT NON-COMPLIANCE IS A
VIOLATION OF THE CLEAN WATER ACT AND MAY REQUIRE ENFORCEMENT ACTION BY THE N.C.
DEPARTMENT OF ENVIRONMENT, HEALTH, AND NATURAL RESOURCES.
12. ON -SITE BURIAL PITS REQUIRE AN ON -SITE DEMOLITION LANDFILL PERMIT FROM THE ZONING
