GENERAL NOTES

1. SCOPE OF WORK: THIS PROJECT INCLUDES MAINTENANCE DREDGING IN

KETCHIKAN'S THOMAS BASIN HARBOR USING MECHANICAL METHODS AS DESCRIBED

IN SECTION 35 20 24.00 29. DREDGED MATERIALS ARE KNOWN TO BE

CONTAMINATED, SEE "ATTACHMENT (1) 2016 THOMAS BASIN - CHEMICAL DATA

REPORT", AND "ATTACHMENT (2) 2015 THOMAS BASIN - CHEMICAL DATA REPORT"

ATTACHED TO SPECIFICATION SECTION 01 57 20.00 10. MEASURES SHALL BE TAKEN

TO MINIMIZE THE SPREAD OF SUSPENDED SEDIMENTS DURING DREDGING AND TO

PREVENT REINTRODUCTION OF DREDGED MATERIAL DURING DEWATERING,

TRANSPORT AND DISPOSAL.

2. STAGING AREA: NO STAGING AREA IS DESIGNATED. COORDINATE WITH THE CITY

OF KETCHIKAN OR PRIVATE LAND OWNER(S).

3. ENVIRONMENT: THE THOMAS BASIN HARBOR ENTRANCE CHANNEL IS SUBJECT TO

HIGH WINDS, WAVES, AND CURRENTS. WAVE HEIGHTS OF UP TO 4' HAVE BEEN

OBSERVED AT THE ENTRANCE CHANNEL. SUCH CONDITIONS CAN AND DO OCCUR

ANY TIME OF THE YEAR. THE CONTRACTOR SHALL PLAN AND PERFORM

CONSTRUCTION ACTIVITIES AND SEQUENCE TO TAKE INTO ACCOUNT SUCH

CONDITIONS.

4. NOISE: THE CONTRACTOR SHALL COMPLY WITH THE CITY OF KETCHIKAN NOISE

ORDINANCE, MUNICIPAL CODE CHAPTER 19.05 - CONSTRUCTION AND EXCAVATION

ACTIVITIES - NOISE RESTRICTIONS.

5. PHOTO SHEETS: PHOTO SHEET C-901 IS PROVIDED FOR INFORMATION ONLY.

6. EXISTING FACILITIES: THE CONTRACTOR SHALL TAKE ALL APPROPRIATE

PRECAUTIONS TO AVOID ANY DISTURBANCE TO THE EXISTING HARBOR FACILITIES.

PRIOR TO BEGINNING CONSTRUCTION, THE CONTRACTOR SHALL PERFORM A

PRE-CONDITION WALK THROUGH WITH THE HARBOR MASTER AND GOVERNMENT

REPRESENTATIVE. THE CONTRACTOR SHALL BE RESPONSIBLE FOR RESTORING

THE PROJECT AREA TO ITS ORIGINAL CONDITION AT HIS OWN EXPENSE UPON

COMPLETION OF THE PROJECT.

7. HARBOR ACCESS: THE CONTRACTOR SHALL COORDINATE WITH THE CITY OF

KETCHIKAN PORT DIRECTOR TO MINIMIZE DISRUPTION OF NORMAL HARBOR

OPERATIONS. THE CONTRACTOR SHALL BE REQUIRED TO PROVIDE ACCESS

THROUGH THE PROJECT SITE FOR BOATS ENTERING OR LEAVING THE HARBOR AT

ALL TIMES.

NOTES

1. PRIMARY PROJECT HORIZONTAL CONTROL IS ALASKA STATE PLANE, ZONE 1, NAD83

(CORS96), IN US SURVEY FEET BASED ON A FULLY CONSTRAINED STATIC GPS NETWORK

HOLDING THE PUBLISHED NAD83 (CORS96) 2010.00 EPOCH VALUES OF NGS CORS

STATIONS: "ANNETTE ISLAND 5 CORS ARP" (AIS5 - PID DK6482); "KLAWOCKAIRAK2006

CORS ARP" (AB49 - PID DM7451) AND "LEVEL ISLAND 6 CORS ARP" (LEV6 - PID DJ3035).

LOCAL PROJECT HORIZONTAL CONTROL IS ALASKA STATE PLANE, ZONE 1, NAD83, IN US

SURVEY FEET HOLDING "TB-3 2001" (PID BBDX22) AS N 1,286,137.51', E 3,107,894.00'.

2. VERTICAL CONTROL IS MEAN LOWER LOW WATER (MLLW=0.0'), BASED ON THE NOAA/NOS

TIDAL BENCH MARK LIST: "945 0460 KETCHIKAN, TONGASS NARROWS, ALASKA "

PUBLISHED 09/27/2011. THIS TIDAL DATUM IS BASED ON THE 1983-2001 TIDAL EPOCH AND

IS REFERENCED BY HOLDING NOAA/NOS TIDAL BENCH MARK "NO 37 1956" (PID: AI4914 /

VM# 1170) AS 35.09'.

3. VERTICAL TIES TO THE NATIONAL SPATIAL REFERENCE SYSTEM ARE BASED ON

PUBLISHED NAVD88 ELEVATIONS HOLDING NOAA TIDAL BENCHMARK "BM NO 37 1956" (PID

AI4914 / VM# 1170) AS 31.27’.

4. SOUNDINGS ARE IN US SURVEY FEET AND ARE MINUS UNLESS OTHERWISE INDICATED.

5. BATHYMETRY WAS COLLECTED FEBRUARY 22 & MARCH 22, 2017. SOUNDINGS WERE

COLLECTED USING AN R2SONIC 2024 MULTIBEAM ECHOSOUNDER OPERATING AT 200 KHZ.

SOUND VELOCITY THROUGH THE WATER COLUMN WAS DETERMINED WITH AN AML BASE

X SOUND VELOCITY PROBE. POSITION AND VESSEL ORIENTATION WERE MEASURED

USING AN APPLANIX POSMV OCEANMASTER V5 SYSTEM. DATA WAS COLLECTED AND

PROCESSED USING QINSY 8.1 SOFTWARE. HORIZONTAL CONTROL WAS SURVEYED USING

RTK GNSS EQUIPMENT AND TECHNIQUES. VERTICAL CONTROL WAS SURVEYED USING

DIFFERENTIAL LEVELING TECHNIQUES.

6. THIS DRAWING INDICATES GENERAL CONDITIONS AT THE TIME OF THE SURVEY.

7. MAP SOUNDINGS ARE BINNED AT 24 FEET AND ARE SHOAL BIASED. CONTOURS ARE

BASED ON 12 FEET BINNED SHOAL-BIASED SOUNDINGS.

TEST BORING NOTES:

1. THE SUBSURFACE EXPLORATION OF THIS PROJECT WAS CONDUCTED ON 27 SEPTEMBER 2016. A TOTAL OF 3 VIBRACORE SAMPLING TUBES WERE ADVANCED TO DEPTHS FROM

7.0 TO 9.5 FEET BELOW THE MUDLINE. THE BORINGS HAVE BEEN DESIGNATED AP-01 THROUGH AP-03. THE ENGINEER RESEARCH AND DEVELOPMENT CENTER (ERDC) PROVIDED

THE EQUIPMENT AND CREW TO PERFORM THE SAMPLING. AN ENGINEER WITH THE U.S. ARMY CORPS OF ENGINEERS, ALASKA DISTRICT LOGGED THE TEST BORINGS.

2. SOIL CLASSIFICATIONS AND DESCRIPTIONS REPORTED ON THE EXPLORATION LOGS ARE IN ACCORDANCE WITH ASTM D 2488, STANDARD PRACTICE FOR DESCRIPTION AND

IDENTIFICATION OF SOILS (VISUAL MANUAL PROCEDURE) AND ASTM D 2487, STANDARD PRACTICE FOR CLASSIFICATION OF SOILS FOR ENGINEERING PURPOSES (UNIFIED SOIL

CLASSIFICATION SYSTEM).

3. THE SOIL CLASSIFICATIONS AND DESCRIPTIONS CONTAINED ON THE EXPLORATION LOGS ARE THE PROJECT ENGINEER'S INTERPRETATION OF THE FIELD LOGS AND RESULTS

OF THE LABORATORY TESTING PROGRAM. THE STRATIFICATION LINES SHOWN ON THE EXPLORATION LOGS REPRESENT APPROXIMATE BOUNDARIES BETWEEN SOIL TYPES.

THE ACTUAL TRANSITIONS ARE OFTEN GRADUAL OR NOT DISCERNIBLE.

4. TEST BORING LOCATIONS WERE LOCATED BY AN ENGINEER WITH THE U.S. ARMY CORPS OF ENGINEERS, ALASKA DISTRICT USING A HANDHELD MAGELLAN PROMARK 3 GLOBAL

POSITIONING SYSTEM. TEST BORING COORDINATES ARE REPORTED ON THE EXPLORATION LOGS ARE BASED ON NAD83 ALASKA STATE PLANE (ASPC), ZONE 1, IN U.S. FEET.

THE MUDLINE ELEVATIONS WERE DETERMINED BY IMPORTING THE HORIZONTAL LOCATIONS OF THE TEST BORINGS INTO A CAD DRAWING TITLED "PROJECT CONDITION

SURVEY", DATED 30 SEPTEMBER 2015. MUDLINE ELEVATIONS WERE SELECTED FROM THE DIGITAL SURFACE WITHIN THE BATHYMETRY SURVEY DRAWING. VERTICAL CONTROL

FROM THE SURVEY DATED 30 SEPTEMBER 2015 IS REFERENCED TO MLLW BASED ON PUBLISHED NAVD88 ELEVATIONS HOLDING NOAA TIDAL BENCHMARK "NO 37 1956" (PID

AI4914 / VM# 1170) AS 31.27’.

NOTES:

1. BACKGROUND IMAGE IS A DIGITAL GLOBE GEO-REFERENCED IMAGE TAKEN ON 13

APRIL 2013.

2. THE CONTRACTOR SHALL SEPARATE AND PROPERLY DISPOSE OF ALL VISIBLY

EVIDENT MAN-MADE MATERIALS AND DEBRIS ENCOUNTERED DURING DREDGING

ACTIVITIES. SEE SECTION 35 20 24.00 29 FOR A DESCRIPTION OF THE INCIDENTAL

WORK REQUIRED.

3. THE DREDGE BASIN, AS DEFINED BY THE TABLE OF DREDGE LIMITS COORDINATES,

DOES NOT INCLUDE THE REQUIRED SIDE SLOPE AREAS. DREDGED 3H:1V SIDE

SLOPES AROUND THE OUTSIDE OF THE PERIMETER OF THE DREDGE BASIN ARE

REQUIRED.

4. CIVIL SHEET CONTOURS, CROSS SECTIONS, AND ALL PROJECT VOLUMES ARE

BASED ON MEAN VALUE SOUNDINGS BINNED AT 3 FEET FROM THE 2017 PROJECT

CONDITION SURVEY AS SHOWN ON SHEETS V-101 AND V-102.

5. REFERENCE SHEET V-101 FOR HORIZONTAL AND VERTICAL SURVEY CONTROL AND

DATUMS.

6. SURVEY LIMITS SHOWN ARE NOT INTENDED TO IMPLY A REQUIREMENT FOR

TOPOGRAPHIC SURVEY WITH REGARDS TO HARBOR FLOATS AND OVERLAP ON

ADJACENT UPLANDS. SURVEY LIMITS SHALL BE COVERED BY HYDROGRAPHIC

METHODS MAKING FULL USE OF TIDAL VARIATIONS. FULL BOTTOM COVERAGE

UNDER HARBOR FLOATS IS NOT REQUIRED AS INDICATED BY AREAS MARKED

"INACCESSIBLE" FROM THE 2017 PROJECT CONDITION SURVEY.
