GENERAL NOTES

1. ACCURATE SURVEY OF THE SEAWARD SLOPE OF THE EXISTING

PROTECTED SHORELINE IS UNAVAILABLE. CONTOURS SHOWN ON THE

PLANS ARE BASED ON SHOTS AT THE TOP AND BOTTOM OF THE

REVETMENT. AS-BUILT DETAILS OF THE EXISTING PROTECTED

SHORELINE ARE NOT AVAILABLE. THE SHORELINE CONTOURS SHOULD

BE CONSIDERED APPROXIMATE AND SHALL BE VERIFIED DURING THE

CONSTRUCTION.

2. CONTRACTOR SHALL REMOVE AND RELOCATE EXISTING DOLOS UNITS

AND STONE WITHIN THE LIMITS OF THE DREDGE MATERIAL DISPOSAL

AREA TO THE FACE OF THE PROPOSED REVETMENT. IT IS ASSUMED

THAT THE DOLOS LAYER IS ONE UNIT THICK CONSISTENT WITH THE

ORIGINAL DESIGN PLANS. THICKNESS OF THE DOLOS LAYER IN THE

EXISTING REVETMENT SHALL BE VERIFIED DURING THE

CONSTRUCTION.

3. RELOCATE EXISTING STONE LANDSIDE OF THE DOLOSES.

4. THE 5 TONNE EXISTING DOLOS SHALL BE USED ON THE EASTERN

SEGMENT OF THE REVETMENT STARTING AT STA 1+168 AND MOVING

NORTH AND WEST UNTIL THE SUPPLY OF THE DOLOS IS EXHAUSTED.

NEW 2.85 TONNE DOLOS SHALL BE USED TO COMPLETE THE EASTERN

SEGMENT UP TO THE TRANSITION SEGMENT.

5. THE CONTRACTOR SHALL CONSTRUCT DEMONSTRATIONS SECTIONS

AS DEFINED IN SPECIFICATION SECTION 35 31 19, PART 3.1.

DEMONSTRATION SECTIONS SHALL BE PROVIDED FOR THE

RELOCATED DOLOSES, THE EASTERN AND WESTERN REVETMENT

SEGMENTS. REFER TO SHEETS CH-301, CH-302, AND CH-303.

6. TRANSITION SECTION OF THE REVETMENT SHALL BE CONSTRUCTED

USING 1.62 TO 2.85 TONNE DOLOS ARMOR UNITS.

7. CONSTRUCTION OF WESTERN REVETMENT SEGMENT WILL CONSIST

OF 1.62 TONNE DOLOS ARMOR UNITS. BROKEN FRAGMENTS OF THE

EXISTING DOLOS AND SALVAGED ROCK MAY BE USED TO CONSTRUCT

THE WESTERN END OF THE REVETMENT FROM STATION 0+00 TO 0+50

PROVIDED THE WEIGHT OF THE UNIT IS NOT LESS THAN 1 TONNE.

8. THE NEW REVETMENT WILL START ON THE ROCK UNDERLAYER

EXPOSED AFTER THE REMOVAL OF THE DOLOS LAYER. THE SLOPE OF

THE ROCK UNDERLAYER IS UNKNOWN. IT IS ASSUMED THAT THE ROCK

UNDERLAYER IS AT A SLOPE OF 2:1 (H:V) CONSISTENT WITH THE

ORIGINAL DESIGN PLANS. THE UNDERLAYER ROCK SLOPE SHALL BE

VERIFIED DURING THE CONSTRUCTION OF THE DEMONSTRATION

SECTIONS.

9. THE ROCK UNDERLAYER OF THE EXISTING SHORELINE THAT IS

EXPOSED BY THE REMOVAL OF THE DOLOS SHALL BE SMOOTHLY

BLENDED WITH THE ROCK UNDERLAYER OF THE NEW EASTERN

REVETMENT SEGMENT.

10. ON THE EASTERN SEGMENT JUNCTION, THE DOLOS ARMOR LAYER ON

THE SEAWARD FACE OF THE REVETMENT SHALL BE SMOOTHLY

BLENDED WITH THE EXISTING DOLOS REVETMENT.

11. ON THE WESTERN SEGMENT JUNCTION, THE SEAWARD FACE OF THE

REVETMENT CONSISTING OF A COMBINATION OF 1.6 TONNE DOLOS,

BROKEN EXISTING DOLOS FRAGMENTS AND/OR SALVAGED ROCK

SHALL BE SMOOTHLY BLENDED WITH THE EXISTING DOLOS ARMOR.

12. BROKEN DOLOSES, NOT USED IN REVETMENT RECONSTRUCTION MAY

BE PLACED ON THE TOE PROTECTION FOR ADDITIONAL

REINFORCEMENT PROVIDED THEIR WEIGHTS ARE NOT LESS THAN

THAT REQUIRED IN THE DESIGN OF THE TOE PROTECTION BERM.

13. PROPOSED REVETMENT STRUCTURE CONSISTS OF PRECAST

CONCRETE ARMOR UNITS (DOLOS), ROCK UNDERLAYER, AND CORE

MADE OF GEOTEXTILE FILTER TUBES.

14. GEOTEXTILE FILTER TUBES ARE TO BE DETAILED DESIGNED BY THE

SELECTED CONTRACTOR.
