GENERAL NOTES:
1. SOUNDINGS ARE IN FEET AND TENTHS. THE REFERENCE PLANE IS MEAN LOWER LOW WATER
(MLLW) AND IS BASED ON THE 1983-2001 TIDAL EPOCH. ANY SOUNDINGS NOTED WITH A PLUS
SIGN (+) ARE ABOVE THE REFERENCE PLANE OF MLLW. ANY SOUNDINGS WITHOUT A SIGN ARE
BELOW THE REFERENCE PLANE OF MLLW AND SHALL BE CONSIDERED NEGATIVE.
2. TOPOGRAPHY SHOWN IS FROM PREVIOUS SURVEYS AND/OR NOAA CHART NO. 13292. ALL
TOPOGRAPHY, INCLUDING SHORELINE, BRIDGES, PIERS, ETC., SHOWN ARE LOCATED
APPROXIMATE UNLESS OTHERWISE NOTED AND SHALL BE USED AS A GENERAL REFERENCE
ONLY.
3. BENCHMARK DATA: TIDES WERE RECORDED USING RTK GPS.THE MLLW TO NAVD88 CORRECTION
FOR THIS PROJECT IS 5.34 FEET. THE CORRECTION IS REFERENCED FROM NOAA'S V-DATUM
MODEL IN THE VICINITY OF GREAT CHEBEAGUE ISLAND, MAINE. NAVD88 IS ABOVE MLLW,
THEREFORE THE CORRECTION SHALL BE ADDED TO NAVD88 TO CONVERT TO MLLW. NO TIDE
GAUGES WERE USED ON THIS PROJECT. AVERAGE RANGE OF TIDE IS 9.1 FEET.
4. COORDINATES SHOWN ARE BASED ON THE TRANSVERSE MERCATOR GRID SYSTEM FOR THE
STATE OF MAINE, (MAINE WEST, ME-1802 NAD 83) AND ARE BASED ON U.S. SURVEY FEET.
5. SURVEY WAS PERFORMED USING AN R2 SONIC 2024 MULTIBEAM SONAR SYSTEM OPERATING AT
300 KHZ. HORIZONTAL POSITIONING AND REAL TIME TIDE READINGS WERE RECORDED UTILIZING
A TRIMBLE SPS 855 RTK GPS SYSTEM. THE RTK BASE STATION USED WAS STATION "GREAT
(2012)".
6. THE SOUNDING INFORMATION SHOWN ON THE DRAWINGS REPRESENTS THE SHOALEST
SOUNDINGS OF THOSE OBTAINED FROM HYDROGRAPHIC SURVEYS CONDUCTED DURING JULY
OF 2021.
7. THE SOUNDING INFORMATION DEPICTED ON THE DRAWINGS SHALL NOT BE USED TO DETERMINE
VOLUMES. VOLUMES ARE DETERMINED FROM MORE SOUNDING INFORMATION THAN SHOWN.
8. THE INFORMATION DEPICTED ON THE DRAWINGS REPRESENTS THE RESULTS OF SURVEYS MADE
ON THE DATES INDICATED, AND CAN ONLY BE CONSIDERED AS INDICATING THE GENERAL
CONDITIONS EXISTING AT THAT TIME.
9. FIELD BOOK: R&H 3127;
SURVEYED BY: MICHAEL VADNAIS AND CREW
REFER TO SURVEY NO.: ME_68_CHB_20210715_CS_033
10. AERIAL ORTHO PHOTO IMAGERY SHOWN IS DATED 2018 AND WAS OBTAINED BY THE NATIONAL
AGRICULTURE IMAGERY PROGRAM (NAIP). THE AERIAL IMAGERY SHOWN ON THESE DRAWINGS
ARE FOR GENERAL INFORMATION ONLY AND IS NOT TO BE USED FOR MEASUREMENTS.

NOTES:
1. REFER TO SHEET G-002 FOR GENERAL NOTES AND LEGEND.
2. REFER TO SHEET G-003 FOR CONTROL LINE LAYOUT AND
COORDINATES.
3. REFER TO SHEET G-003 FOR CORE SAMPLE LOCATIONS. CORE
SAMPLE LOCATIONS NOT SHOWN ON THIS SHEET FOR CLARITY.
4. REFER TO SHEET C-301 FOR SECTIONS AND PROFILE.
5. DISTURBANCE OF EELGRASS IS ALLOWED BETWEEN LIMITS OF
CHANNEL (TOE OF SLOPE) AND LIMIT OF DREDGING ALONG
SIDE SLOPES. ALSO REFER TO SECTIONS ON C-301 FOR
GRAPHICAL REPRESENTATION.
6. REFER TO SUBPART TITLED "EELGRASS" IN SPECIFICATION
SECTION 01 57 19 TEMPORARY ENVIRONMENTAL CONTROLS
FOR ADDITIONAL RESTRICTIONS.
7. THIRTY (30) DAYS PRIOR TO THE START OF DREDGING
OPERATIONS THE CONTRACTOR SHALL COORDINATE WITH THE
HARBORMASTER FOR THE TEMPORARY REMOVAL OF WOODEN
FLOAT 1. AFTER THE CONTRACTOR DEMOBILIZES, THE
HARBORMASTER WILL REINSTALL WOODEN FLOAT 1. WOODEN
FLOATS 2 AND 3, AND FLOATING WALKWAYS SHALL REMAIN IN
PLACE AND UNDISTURBED.
8. BOULDERS MAY BE ENCOUNTERED WHILE DREDGING THE
TURNING BASIN IN THE VICINITY OF CORE SAMPLE H (SEE
SHEET G-003). REFER TO OPTIONAL BID ITEM IN BID SCHEDULE
AND SECTION 01 22 00, MEASUREMENT AND PAYMENT.
