ANCHORAGE HARBOR NOTES:

1. PRIMARY HORIZONTAL CONTROL IS ALASKA STATE PLANE, NAD 83 (2011) EPOCH

2010.00, ZONE 4, IN U.S. SURVEY FEET DERIVED FROM STATIC GPS MEASUREMENTS

ORIGINATING FROM AND HOLDING NGS STATIONS "VAN DUSEN" (PID TT4676), "LOOP2 RM3"

(PID UV4446), AND NGS CORS STATIONS "ANC2" (PID DL6498), "TBON" (PID DK4055), "TSEA"

(PID AI0952), "ZAN1" (PID DE9153).

2. VERTICAL CONTROL: ELEVATIONS ARE MEAN LOWER LOW WATER (MLLW)BASED ON

THE 1983-2001 TIDAL EPOCH EXPRESSED IN US FEET. THE BASIS OF ELEVATIONS IS

NOAA/NOS TIDE STATION 9455920 "ANCHORAGE, KNIK ARM, COOK INLET, ALASKA"

PUBLISHED 10/24/2011 HOLDING "NO 15 RESET 1966" (VM# 1332) AS 37.14'.

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

PUBLISHED NAVD88 (GEOID 12A) ELEVATIONS HOLDING NOAA/USACE TIDAL BENCHMARK

"9455920 TIDAL 16" (PID TT0713/VM# 1335) AS 29.79'.

4. ALL DREDGED MATERIAL FROM THE ANCHORAGE HARBOR SHALL BE TRANSPORTED

TO AND DEPOSITED IN THE ANCHORAGE HARBOR DISPOSAL SITE.

5. THE SEAWARD EDGE OF THE EXISTING DOCK FACE WAS VERIFIED IN FEBRUARY, 2013

BY DOWL HKM USING RTK SURVEYING TECHNIQUES. THE LINE ESTABLISHING THE SEAWARD

EDGE OF THE DOCK FACE ACCOUNTS FOR CONCRETE/TIMBER CURBING AND BUMPERS BUT

DOES NOT ACCOUNT FOR PILINGS. IN ADDITION TO THE VERTICAL PILES, SOME AREAS

ALONG THE DOCK HAVE BATTERED PILES THAT ANGLE AWAY FROM THE DOCK FACE AS

SHOWN ON SHEET C-301. THE LOCATIONS WHERE THE PILES ENTER THE MUD LINE WERE

NOT VERIFIED DURING THIS SURVEY. THE LOCATION OF THE SOUTH FLOAT, NORTH FLOAT,

AND SHEETPILE WALL IN THE NORTH PORT EXPANSION ALSO WERE NOT VERIFIED DURING

THIS SURVEY.

6. AERIAL IMAGERY WAS EXPORTED FROM THE BING MAPS WEB SERVICE AVAILABLE

THROUGH ESRI SOFTWARE. THE EXACT DATE OF THE IMAGE IS UNKNOWN. THE AERIAL

IMAGERY IS FOR GENERAL REFERENCE ONLY. THE CONTRACTOR SHALL BE RESPONSIBLE

FOR VERIFYING THE ACTUAL LOCATION AND CONDITION OF FEATURES IN THE VICINITY OF

THIS PROJECT SITE.

COOK INLET NAVIGATION CHANNEL (CINC) NOTES:

1. PRIMARY HORIZONTAL CONTROL IS ALASKA STATE PLANE, NAD 83 (2011) EPOCH 2010.00, ZONE 4, IN U.S. SURVEY FEET DERIVED FROM STATIC GPS MEASUREMENTS ORIGINATING

FROM AND HOLDING NGS STATIONS "VAN DUSEN" (PID TT4676), "LOOP2 RM3" (PID UV4446), AND NGS CORS STATIONS "ANC2" (PID DL6498), "TBON" (PID DK4055), "TSEA" (PID AI0952), "ZAN1" (PID DE9153).

2. VERTICAL CONTROL IS A TILTED-PLANE MLLW DATUM DERIVED IN 2013 AND BASED ON

THE NOAA/NOS TIDAL BENCH MARK LISTS "9455920, ANCHORAGE, KNIK ARM, COOK INLET,

ALASKA" PUBLISHED 10/24/2011, "9455912, FIRE ISLAND, ALASKA" PUBLISHED 05/21/2004, AND

"9455934, PORT MACKENZIE, COOK INLET, ALASKA" PUBLISHED 05/23/2003. THIS

TILTED-PLANE MLLW IS BASED ON THE 1983-2001 TIDAL EPOCH AT THOSE STATIONS AND IS

REFERENCED BY HOLDING GPS CONTROL STATION "TERRA 11" (PID BBCT04) AS 80.48 FT.

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

PUBLISHED NAVD88 (GEOID 12B) ELEVATIONS HOLDING “TIDAL 16" (PID

TT0713/VM#1335) AS 29.79 FT. ELLIPSOIDAL HEIGHTS SHOWN ON THIS SHEET ARE BASED ON

THE NAD83 (2011) EPOCH 2010 REFERENCE ELLIPSOID.

4. ALL DREDGED MATERIAL FROM CINC SHALL BE TRANSPORTED TO AND DEPOSITED IN THE

CINC OPEN WATER DISPOSAL SITE. THE ELEVATION OF THE DREDGED MATERIAL IN THE

CINC DISPOSAL SITE SHALL NOT BE HIGHER THAN -45 FEET MLLW. THE CONTRACTOR SHALL

VARY PLACEMENT LOCATIONS WITHIN THE CINC DISPOSAL SITE SO AS TO AVOID BUILDING

A MOUND IN ONE LOCATION. THE CONTRACTOR SHALL MAINTAIN AN OFFSET OF 328 FEET

FROM THE KODIAK KENAI FIBER LINK (KKFL) AS DEFINED BY CORNERS DS-8 AND DS-9. A

PRE-DREDGE SURVEY OF THE CINC DISPOSAL SITE SHALL BE CONDUCTED AT LEAST ONCE

PER DREDGE SEASON IN WHICH THE SITE IS USED.

5. THE CONTRACTOR SHALL BE RESPONSIBLE FOR UTILITY LOCATES PRIOR TO ANY

DREDGE OPERATIONS FOR CINC. THE UTILITY AREAS SHOWN IN THIS DRAWING ARE

APPROXIMATE BASED ON INFORMATION FROM CHUGACH ELECTRIC ASSOCIATION (CEA),

GENERAL COMMUNICATION INC. (GCI), AND NOAA. THE DREDGE SHALL MAINTAIN A MINIMUM

200 FOOT OFFSET FROM THE CEA CABLE FIELD AS DEFINED BY DL-27, DL-28, AND DL-29 IN

THE TABLE BELOW. THE CONTRACTOR SHALL NOT PLACE DREDGE EQUIPMENT SUCH AS

ANCHORS, BUCKETS, DRAG HEADS, ETC. IN THESE AREAS. REFERENCE NOAA CHART 16665

PROVIDED ON SHEET G-101 FOR FURTHER INFORMATION REGARDING UTILITY AREAS IN THE

VICINITY OF THIS PROJECT SITE.

6. NAVIGATION AIDS PROVIDED IN THIS DRAWING WERE OBTAINED FROM THE U.S. COAST

GUARD LIGHT LIST, VOLUME VI, AS PUBLISHED FOR 2014. THIS INFORMATION IS FOR

GENERAL REFERENCE ONLY. THE CONTRACTOR SHALL BE RESPONSIBLE FOR VERIFYING

INFORMATION CORRECTED IN THE LOCAL NOTICES TO MARINERS OR NOTICES TO

MARINERS AS APPROPRIATE.
