GENERAL NOTES

1. CUT AND CLEAR ALL VEGETATION IN THE PROJECT SITE WITHIN ACCESS ROAD (REVETTED MOLE ONLY) AND WORK TASK AREAS IN ACCORDANCE WITH

LANDSCAPING NOTES BEFORE COMMENCING TASKS 1 THROUGH 5.

2. PLACE SERIES OF WOOD MATS FOR TRACKED EQUIPMENT TO TRAVEL OVER TEMPORARY ACCESS ROAD (EAST BREAKWATER ONLY) TO REDUCE GROUND AND VEGETATION DISTURBANCE. BEST MANAGEMENT PRACTICES (E.G., USE OF STEEL PLATES) SHALL BE USED TO PROTECT EXISTING SIDEWALK FROM DAMAGE DUE

TO INGRESS AND EGRESS OF CONSTRUCTION EQUIPMENT.

3. EXISTING STRUCTURES OR IMPROVEMENTS DAMAGED AS A RESULT OF CONTRACTOR'S OPERATIONS DURING WORK SHALL BE REPAIRED BY CONTRACTOR AT HIS EXPENSE. STRUCTURES THAT ARE TO BE PROTECTED FROM DAMAGE OR REPAIRED IF DAMAGED INCLUDE BUT ARE NOT LIMITED TO SIDEWALKS, GAZEBOS, SIGNAGE, PARKING AREAS, PRIVATE AND PUBLIC ROADS, AND OTHER STRUCTURES OR IMPROVEMENTS.

4. STAGING AREA SHOWN ON SHEET C-101 IS THE PROPERTY OF GUAM WATERWORKS AUTHORITY (GWA). CONTRACTOR IS TO COORDINATE ACCESS AND STAGING AREA SECURITY WITH PORT AUTHORITY OF GUAM AND GWA. STAGING AREA DOES NOT HAVE ANY PROVISIONS (WATER, UTILITIES, ELECTRICITY) FOR CONTRACTOR'S USE.

5. WORK TASKS FOR THIS PROJECT INCLUDE THE FOLLOWING:

5.1. WORK TASK 1 CONSISTS OF REPAIR TO THE APRON SECTION (HARBOR SIDE OF REVETTED MOLE) FROM STATION 0+00 TO STATION 3+65. TYPICAL DAMAGE IS INDICATED ON SHEET C-501, SECTION B5. REWORK EXISTING STONE AND REMOVE EXISTING VEGETATION INCLUDING ROOTS AND FILL (NON-ROCK MATERIAL). PLACE NEW BEDDING STONE TO MEET THE LINES AND GRADES SHOWN ON THE DRAWINGS.

5.2. WORK TASK 2 CONSISTS OF REPAIR TO THE APRON SECTION (HARBOR SIDE OF REVETTED MOLE) FROM STATION 5+10 TO STATION 9+50. TYPICAL DAMAGE IS INDICATED ON SHEET C-501, SECTION B5. REWORK EXISTING STONE AND REMOVE EXISTING VEGETATION INCLUDING ROOTS AND FILL (NON-ROCK MATERIAL).

PLACE NEW BEDDING STONE TO MEET THE LINES AND GRADES SHOWN ON THE DRAWINGS.

5.3. WORK TASK 3 CONSISTS OF REPAIR TO THE APRON SECTION (HARBOR SIDE OF REVETTED MOLE) FROM STATION 9+50 TO STATION 10+65. TYPICAL DAMAGE IS INDICATED ON SHEET C-502, SECTION J6. REWORK EXISTING STONE AND REMOVE EXISTING VEGETATION INCLUDING ROOTS AND FILL (NON-ROCK MATERIAL)

TO MEET THE LINES AND GRADES SHOWN ON THE DRAWINGS.

5.4. WORK TASK 4 CONSISTS OF REPAIR TO THE SEAWARD SLOPE OF REVETTED MOLE FROM STATION 7+25 TO STATION 9+25. TYPICAL DAMAGE IS INDICATED ON SHEET C-501, SECTION B5. REWORK EXISTING STONE TO MEET THE LINES AND GRADES SHOWN ON THE DRAWINGS.

5.5. WORK TASK 5 CONSISTS OF IDENTIFYING AND RESETTING DISPLACED TOE STONES AT BASE OF THE WEST BREAKWATER. DISPLACED TOE STONES ARE LARGER STONES (GREATER THAN 1' IN DIAMETER) THAT ARE NO LONGER ATTACHED TO THE STRUCTURE. KNOWN DETACHED STONES ARE IDENTIFIED ON SHEET C-103. CONTRACTOR SHALL CONFIRM THE LOCATION OF EACH DISPLACED TOE STONE TO BE REWORKED WITH CONTRACTING OFFICER'S REPRESENTATIVE PRIOR TO CONSTRUCTION ACTIVITIES. DISPLACED TOE STONES THAT HAVE THE PRESENCE OF CORAL GROWTH ARE SHOWN ON C-103 AND

SHALL BE REPLACED WITH NEW STONES.

5.6. WORK TASK 6 CONSISTS OF IDENTIFYING AND RESETTING DISPLACED TOE STONES AT BASE OF THE EAST BREAKWATER. DISPLACED TOE STONES ARE LARGER STONES (GREATER THAN 1' IN DIAMETER) THAT ARE NO LONGER ATTACHED TO THE STRUCTURE. KNOWN DETACHED STONES ARE IDENTIFIED ON SHEET C-104. CONTRACTOR SHALL CONFIRM THE LOCATION OF EACH DISPLACED TOE STONE TO BE REWORKED WITH CONTRACTING OFFICER'S REPRESENTATIVE PRIOR TO CONSTRUCTION ACTIVITIES.

SHALL BE REPLACED WITH NEW STONES.

LANDSCAPING NOTES

1. CONTRACTOR SHALL CUT AND CLEAR ALL EXISTING VEGETATION TO A MINIMUM OF:

a. FLUSH WITH THE SURFACE OF THE REVETMENT/GROUND FOR LARGER VEGETATION (TRUNK CALIPERS 3-INCHES AND LARGER).

b. FLUSH WITH THE SURFACE OF THE REVETMENT/GROUND SURFACE FOR ALL OTHER VEGETATION.

c. ALL CUTS SHALL BE CLEAN AND HORIZONTAL TO THE REVETMENT/GROUND SURFACE TO AVOID POTENTIAL INJURY. SLANTED CUTS WILL NOT BE

ALLOWED.

2. FOR AREAS OF THE REVETTED MOLE WHERE RECONSTRUCTION WORK WILL OCCUR, THE CONTRACTOR SHALL COMPLETELY REMOVE ALL VEGETATION INCLUDING, BUT NOT LIMITED TO, TREES (INCLUSIVE OF ALL ROOTS) AND ALL SHRUB AND GROUND COVERS IN THE AREAS SHOWN TO BE REPAIRED ON THE PLANS. ALL WORK SHALL BE COORDINATED WITH THE USACE-POH PROJECT MANAGER, CONTRACTING OFFICER'S REPRESENTATIVE, AND GENERAL CONTRACTOR TO DETERMINE THE EXTENT OF ANY TREE REMOVAL PRIOR TO PERFORMING THE TREE REMOVAL WORK.

3. CONTRACTOR SHALL REMOVE ALL DEBRIS AND LANDSCAPE MATERIALS (GENERATED FROM VEGETATION REMOVAL) FROM THE PROJECT SITE. DEBRIS SHALL BE LEGALLY DISPOSED OF ACCORDING TO LOCAL CODES. LANDSCAPE CUTTINGS SHALL BE TAKEN TO A GREEN WASTE FACILITY. CONSTRUCTION

DEBRIS SHALL NOT BE ALLOWED TO ENTER THE WATER.

4. CONTRACTOR SHALL APPLY A SYSTEMIC HERBICIDE APPROVED FOR AQUATIC USE BY THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY (EPA)
