NOTES

1. HORIZONTAL CONTROL IS ALASKA STATE PLANE, ZONE 1, NAD83(2011) IN U.S. SURVEY FEET BASED ON

LOCAL CONTROL MONUMENT "DHAR" AS N 2,354,095.52, E 2,546,726.69 AND "DH-D 2000" AS N 2,353,359.31, E

2,547,126.72.

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

LIST: "945 2210, JUNEAU, GASTINEAU CHANNEL, STEPHENS PASS, ALASKA", PUBLISHED 10/20/2011. THIS

TIDAL DATUM IS BASED ON THE 2002-2006 TIDAL EPOCH AND IS REFERENCED BY HOLDING NOAA TIDAL

BENCH MARK "JNU TIDAL GPS 1999" (PID AI4908, VM# 16187) AS 29.16' AND NOAA TIDAL BENCH MARK "2210 K

2011" (VM# 20160) AS 26.88'.

3. VERTICAL TIES TO THE NATIONAL SPATIAL REFERENCE SYSTEM ARE BASED ON PUBLISHED NAVD88

ELEVATIONS HOLDING THE OPUS DB PUBLISHED VALUES OF "JNU TIDAL GPS 1999" (PID AI4908, VM#16187)

AS 20.30'.

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

5. THE EXISTING PROJECT CONSISTS OF DOUGLAS HARBOR LOCATED IN DOUGLAS, ALASKA.

6. THE SURVEY WAS CONDUCTED ON MAY 6 & 8, 2013. HYDROGRAPHIC SOUNDING DATA WAS COLLECTED

USING AN ODOM ES3 MULTI-BEAM ECHOSOUNDER (200KHZ, 120-DEGREE SWATH-WIDTH WITH 480, 0.75

DEGREE BEAMS). POSITIONING AND VESSEL ATTITUDE WERE PROVIDED IN REAL TIME USING A TRIMBLE

461 RTK GPS RECEIVER OPERATING ON KINEMATIC CORRECTORS BROADCAST FROM A TRIMBLE R8 RTK

BASE RECEIVER SET AT CONTROL STATION, "DH-C". SOUND VELOCITY PROFILE WAS PROVIDED USING AN

ODOM DIGI-BAR PRO, AND WAS PROVIDED IN REAL TIME AT THE SOUNDER HEAD USING AN ODOM DIGI-BAR

V. DATA COLLECTION AND NAVIGATION WERE PERFORMED USING HYPACK HYSWEEP (2013) SOFTWARE.

MULTI-BEAM SURVEY DATA WAS POST-PROCESSED USING HYPACK HYSWEEP (2013) SOFTWARE.

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

8. MAP SOUNDINGS ARE BINNED AT 12 FEET AND ARE NEAREST CELL CENTER VALUE. VOLUME SOUNDINGS

ARE BINNED AT 3 FEET AND ARE AVERAGE CELL VALUE.
