SURVEY AND GENERAL NOTES:

1. CONTROL POINT 1 WAS SET WITH A TRIMBLE R8 SYSTEM LOGGING DATA FOR A

STATIC OBSERVATION POINT THIS DATA WAS THEN SENT TO OPUS TO DEVELOP

CONTROL. CONTROL FROM THIS OPUS SOLUTION WAS CALCULATED AS N: 622,145.13

SFT; E: 2,849,817.80 SFT; AND ELEV. 2.16 SFT (NC STATE PLANE 3200 GRID [NAD 83 AND

NAVD 88]). THIS OPUS SOLUTION WAS RECEIVED ON AUGUST 18, 2014. ALL OTHER

SURVEY POINTS TIED TO THIS POINT TO ESTABLISH THE LOCAL GRID. CONTRACTOR

SHALL FIELD VERIFY ALL SURVEY CONTROL POINTS WITHIN THREE (3) WEEKS OF

RECEIPT OF THE NOTICE TO PROCEED. CONTRACTOR SHALL CONTACT NRCS

PROJECT ENGINEER WITHIN FOUR (4) WEEKS OF RECEIPT OF NOTICE TO PROCEED

WITH ANY CONTROL POINT DISCREPANCIES, AFTER SUCH TIME HAS PASSED IT WILL

BE THE ASSUMPTION THAT ALL CONTROL POINTS AS SHOWN ON THE PLANS ARE IN

GOOD STANDING AND CONTRACTOR AGREES WITH PUBLISHED COORDINATES.

2. THIS SURVEY WAS CONDUCTED BY NRCS STAFF WHICH ARE NOT LICENSED SURVEYORS

WITHIN THE STATE OF NORTH CAROLINA. THEREFORE, ALL ELEVATION DATA SHALL BE FIELD

VERIFIED BY THE CONTRACTOR AND THEN COORDINATED WITH THE ENGINEER. THESE

PLANS WERE PREPARED WITH THE FIELD INFORMATION AT THE TIME OF PROJECT SURVEY. IT

IS POSSIBLE THAT FIELD CONDITIONS AT THE TIME OF CONSTRUCTION VARY FROM THESE

PLANS AND IT IS THE CONTRACTOR'S RESPONSIBILITY TO VERIFY FIELD CONDITIONS SUCH AS

ELEVATIONS, DEPTHS, ETC PRIOR TO PROCEEDING WITH WORK. SURVEY DATA COLLECTION

WAS VERY SPARSE DUE TO FIELD CONDITIONS, THEREFORE, ALL ELEVATIONS SHOULD BE

CHECKED IN THE FIELD BY CONTRACTOR PRIOR TO CONSTRUCTION. CONTRACTOR SHALL

CONTACT PROJECT ENGINEER IMMEDIATELY UPON DISCOVERING ELEVATIONS WHICH ARE

DIFFERENT THAN THOSE SHOWN ON THE PLANS.

3. NRCS SHALL HOLD THE CONTRACTOR TO ± 0.05 FT. TOLERANCE ON ALL WATER

CONTROL STRUCTURES, AND TO ± 0.1 FT. TOLERANCE ON ALL OTHER CONSTRUCTION

AND INSTALLED ITEMS.

4. MAINTAIN, RELOCATE OR REPLACE EXISTING SURVEY MONUMENTS, CONTROL POINTS

AND STAKES WHICH ARE DISTURBED OR DESTROYED. PERFORM THE WORK TO

PRODUCE THE SAME LEVEL OF ACCURACY AS THE ORIGINAL MONUMENT(S) IN A

TIMELY MANNER AND AT THE CONTRACTORS EXPENSE.

5. EXISTING TOPOGRAPHY, STRUCTURES AND SITE FEATURES ARE SHOWN SCREENED

AND/OR LIGHT-LINED . NEW FINISHED GRADE, STRUCTURES AND SITE FEATURES ARE

SHOWN AS HEAVY-LINED.

6. ELEVATIONS GIVEN ARE TO SETTLED GRADE UNLESS OTHERWISE SHOWN

7. ALL SLOPES SHALL BE 5:1 OR FLATTER UNLESS OTHERWISE SPECIFIED. SLOPE

UNIFORMLY BETWEEN CONTOURS AND SPOT ELEVATIONS SHOWN.

RECOMMENDED CONSTRUCTION SEQUENCE

CONTRACTOR SHALL SUBMIT A WRITTEN REQUEST TO NRCS PROJECT ENGINEER TWO

WEEKS IN ADVANCE FOR ANY DEVIATION FROM THE FOLLOWING SCHEDULE, FOR ANY

UNFORESEEN CIRCUMSTANCE.

1. CONTRACTOR SHALL ACCESS THE PROJECT AS SHOWN ON SHEET 3 OF THIS PLAN

SET.

2. CONTRACTOR SHALL INSTALL SEDIMENT AND EROSION CONTROL PRACTICES AS

SHOWN IN THE PLANS, SPECIFICATIONS AND /OR AS REQUIRED BY PERMITTING

AUTHORITIES.

3. CONSTRUCTOR SHALL INSTALL DE-WATERING DEVICES PER WATER CONTROL

STRUCTURE FABRICATION ENGINEER, FOLLOWING REVIEW AND CONCURRENCE BY

NRCS ENGINEER.

4. COMMENCE PATHWAY GRADING AS DIRECTED IN THE PLANS AND SPECIFICATIONS.

5. REMOVE AND DISPOSE OF EXISTING PIPES AND/OR WATER CONTROL STRUCTURE

AS DIRECTED IN THE PLANS AND SPECIFICATIONS.

6. COMMENCE WATER CONTROL STRUCTURE INSTALLATION AT LOCATION

DESIGNATED IN PLANS AND SPECIFICATIONS.

7. SEED AND PLANT AREAS IN ACCORDANCE WITH CONSTRUCTION SPECIFICATIONS.

SEEDING SHALL BE CONDUCTED IMMEDIATELY FOLLOWING A BID ITEM BEING

BROUGHT TO FINAL GRADE.

8. CONDUCT PUNCH LIST WALK THROUGH, WITH GOVERNMENT REPRESENTATIVE,

PROJECT ENGINEER, AND PROJECT INSPECTOR.

9. ADDRESS PUNCH LIST ITEMS.

10. STABILIZE THE SITE, IN ACCORDANCE WITH THE PLANS AND SPECIFICATIONS.

11. UPON STABILIZATION, REQUEST APPROVAL FOR THE REMOVAL OF TEMPORARY

SEDIMENT AND EROSION CONTROL DEVICES.

12. REMOVE TEMPORARY SEDIMENT AND EROSION CONTROL DEVICES, AFTER

APPROVAL FROM PROJECT ENGINEER.

13. REMOVE EQUIPMENT FROM PROJECT AREA.
