3. THE EXISTING SHEET PILE BULKHEAD IS TO REMAIN AND MUST NOT BE DAMAGED.

4. THE LIMITS OF THE CONCRETE SIDEWALK AND RAILING REMOVAL AREAS MUST BE FIELD VERIFIED AND COORDINATED WITH THE COR.

DESIGN INTENT IS FOR SIDEWALK TO BE REMOVED TO NEAREST JOINT.

5. LOCATIONS OF EXISTING SUBSURFACE FEATURES (E.G. TIMBER BUTTRESSES AND DEADMEN) HAVE BEEN APPROXIMATED BASED ON

AVAILABLE HISTORIC DRAWINGS FROM 1962-1973 AND DO NOT REPRESENT EXACT LOCATIONS.

6. BORING LOCATIONS ARE APPROXIMATE AND ARE REFERENCED FROM DRAWINGS TITLED "FIGURE I.1 (BORING AND CROSS SECTION LOCATIONS)" AND "RIGHT OF WAY PLAN STA. 300+00 TO STA 310+00" FROM ATTACHMENT 2 OF INDIAN RIVER INLET MAJOR MAINTENANCE REPORT 90% DESIGN DDR, PREPARED BY USACE PHILADELPHIA DISTRICT AND DATED 20DEC2022. TEST PIT LOCATIONS ARE APPROXIMATE AND ARE BASED ON INVESTIGATORY EXCAVATIONS PERFORMED ON 10 MAY 2022. TEST PIT LOGS ARE INCLUDED AS AN APPENDIX TO THE

7. CONTRACTOR MUST REMOVE CONCRETE BLOCKS, GEOTEXTILE FABRIC, DUMPED LEAN CONCRETE, AND OTHER DEBRIS WITHIN TEMPORARY FENCE (BETWEEN EXISTING SIDEWALK AND BLOCK WALKWAY) AS NEEDED TO INSTALL IMPROVEMENTS.

8. CUT TIMBER PILES TO A DEPTH OF 2 FEET BELOW FINISHED GRADE OR AS NEEDED TO INSTALL THE WORK. IF INDIVIDUAL TIMBER PILES ARE FOUND TO INTERFERE WITH INSTALLATION OF POST-AND-PANEL WALL, CUT AND REMOVE AS NEEDED TO ACCOMMODATE POST-AND-PANEL WALL INSTALLATION. FOR BIDDING PURPOSES, ASSUME CUTTING (8) 12-INCH-DIAMETER PILES AND REMOVING 40 TOTAL LF OF TIMBER PILE.

9. TEMPORARILY EXCAVATE BELOW-GRADE REVETMENT MATERIAL AND STOCKPILE FOR BACKFILL PURPOSES. SEE C-301 FOR ANTICIPATED

EXCAVATION EXTENTS.

10. CONTRACTOR MUST PROVIDE SURVEY TO DOCUMENT EXISTING CONDITIONS PRIOR TO CONSTRUCTION. SITE FEATURES THAT ARE TEMPORARILY DEMOLISHED TO FACILITATE CONSTRUCTION MUST BE RESTORED TO ORIGINAL LIMITS AND GRADES AFTER CONSTRUCTION.

NOTES:

1. SEE SHEET C-001 FOR GENERAL INFORMATION.

2. SEE SHEET C-002 FOR SURVEY AND CONSTRUCTION BASELINE GEOMETRY.

3. SEE SHEETS C-302 TO C-304 FOR CROSS SECTIONS.

4. SEE SPECIFICATIONS FOR STONE WEIGHT GRADATION REQUIREMENTS.

5. CAPSTONES (WHERE SHOWN) ARE FOR ILLUSTRATIVE PURPOSES ONLY AND DO NOT REPRESENT ACTUAL CAPSTONE SHAPE/SIZES. AT SOME LOCATIONS, EXISTING MATERIAL WILL NEED TO BE REMOVED TO ALLOW CAPSTONE PLACEMENT, SEE C-303. RIPRAP SLOPE SHOWN IS BASED ON PLACING RIPRAP ON EXISTING SLOPES AT DESIGN

THICKNESS.

6. THE EXISTING GROUND SURFACE HAS BEEN APPROXIMATED FROM VARIOUS SOURCES OF AVAILABLE DATA, INCLUDING HYDROGRAPHIC SURVEY DATA AND AERIAL LIDAR DATA. OTHER EXISTING CONDITIONS (SUCH AS LOCATIONS OF EXISTING SHEET PILE AND TIEBACKS) HAVE BEEN APPROXIMATED BASED ON AVAILABLE HISTORIC DRAWINGS FROM

1962-1973 AND DO NOT REPRESENT EXACT LOCATIONS. SEE REFERENCE DRAWINGS.

7. THE LIMITS OF CAPSTONE AND RIPRAP PLACEMENT MAY BE REVISED AS DIRECTED BY THE GOVERNMENT BASED ON

PRE-CONSTRUCTION SURVEYS AND THE DYNAMIC CONDITIONS OF THE SITE.

8. REMOVE EXISTING CONCRETE BLOCK SIDEWALK WITHIN LIMITS SHOWN ON CD101. REGRADE OR REMOVE EXISTING STONE UNDERLYING CONCRETE BLOCK SIDEWALK AS NEEDED TO ALLOW PLACEMENT OF CAPSTONE AT TOP OF CREST.

9. FOR DIMENSIONS AND SLOPES FOR FEATURES OF WORK, REFER TO THE SITE PLAN ON SHEET C-101 AND THE CROSS

SECTIONS ON SHEETS C-302 TO C-304.

10. FOR BIDDING PURPOSES ASSUME EXISTING TIE RODS AS SHOWN ON THE REFERENCE DRAWINGS NO LONGER EXIST.

11. SHEET PILE SECTION MUST BE AS PER THE PROJECT SPECIFICATIONS.

12. LIMIT OF EXCAVATION TO CONSTRUCT POST AND PANEL WALL MAY VARY. EXISTING REVETMENT (CORESTONE, MATSTONE, ETC.) DOES NOT NEED TO BE RESTORED TO EXISTING CONFIGURATION ON LANDSIDE OF POST-AND-PANEL WALL. AREA MUST BE RESTORED USING PROPERLY PLACED AND COMPACTED FILL TO ACHIEVE REQUIRED COMPACTION PER SPECIFICATIONS. EXCAVATED MATERIALS MAY BE USED TO BACKFILL EXCAVATIONS TO THE EXTENT PRACTICABLE. LARGER ROCKS IN EXCESS OF 12 INCHES CAN BE PLACED AS PART OF BACKFILL, BUT MUST NOT BE "NESTED" TOGETHER CREATING LOCALIZED ROCK POCKETS WITH VOIDS. IF RE-USED, THE ROCKS MUST BE STRATEGICALLY LAID TO ALLOW COMPACTION EQUIPMENT TO BE USED SUCH THAT EACH LIFT (12 INCHES OR LESS)

CAN BE PROPERLY COMPACTED IN ACCORDANCE WITH THE PROJECT SPECIFICATIONS.

13. TOTAL SHEET PILE EMBEDMENT: 50'. TOP OF SHEET PILE ELEVATION: +2.1'. BOTTOM OF SHEET PILE ELEVATION: -47.9'

14. H-PILE EMBEDMENT: VARIES (65.1'±). TOP OF H-PILE: 4.5'±, MATCH FINISH GRADE. BOTTOM OF H-PILE: -60.6. TIMBER LAGGING MUST BE INSTALLED BETWEEN ELEVATIONS TOP OF H-PILE AND -11.5' AT MINIMUM; FOR SPECIFIC REQUIREMENTS INCLUDING THICKNESS OF LAGGING AT DIFFERENT ELEVATIONS, SEE DETAILS 1/C-501 AND 2/C-501

15. AREAS OF SIDEWALK REPLACEMENT (LOWER SIDEWALK ADJACENT TO CAPSTONE CREST AND UPPER SIDEWALK AT SHEET PILE INSTALLATION) MUST BE SLOPED AT APPROXIMATELY 2% TOWARD BULKHEAD. REMAINING SIDEWALK (ARMORING AT EXISTING SAND AREA) WILL DRAIN TOWARD BULKHEAD AT VARYING SLOPES AS SHOWN ON

CROSS-SECTIONS.

16. MEAN HIGH WATER (MHW) AND MEAN LOW WATER (MLW) ELEVATIONS FOR INDIAN RIVER INLET WERE ESTIMATED USING NOAA'S VDATUM TOOL AND ARE STATED RELATIVE TO THE NORTH AMERICAN VERTICAL DATUM OF 1988 (NAVD 88).

17. CONTRACTOR MUST PROTECT EXISTING SHEET PILE WALL TO PREVENT DAMAGE DURING ALL CONSTRUCTION

ACTIVITIES.

18. REMOVE OR CUT EXISTING TIMBER BUTTRESSES ONLY AS NECESSARY TO INSTALL SHEET PILE.

19. PERFORM INVESTIGATIONS TO CONFIRM A MINIMUM 24" THICKNESS OF CORESTONE SUBGRADE IS PRESENT IN AREAS WHERE CAPSTONE CREST WILL BE PLACED. IF INSUFFICIENT CORESTONE IS PRESENT, PROVIDE 16 OZ/SY GEOTEXTILE

FABRIC OVER THE SUBGRADE BEFORE PLACING CAPSTONES.

20. SEE ATTACHED DELDOT REFERENCE DRAWINGS FOR INFORMATION ON EXISTING MECHANICALLY STABILIZED EARTH

(MSE) BELOW PROMENADE SIDEWALK.
