GENERAL NOTES:

1. SOUNDINGS SHOWN AT THE SCUSSET BORROW SITE AND ENTRANCE

CHANNEL 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. ALL STRUCTURES AND LAND FEATURES, INCLUDING SHORELINE,

BRIDGES, PIERS, ETC., SHOWN ARE FROM NOAA CHART 13236 AND

2022 AERIAL IMAGERY AND ARE LOCATED APPROXIMATE UNLESS

OTHERWISE NOTED AND SHALL BE USED AS A GENERAL REFERENCE

ONLY.

3. BENCHMARK DATA FOR SCUSSET BORROW SITE AND CHANNEL: TIDES

WERE RECORDED USING RTK GPS. A HYPACK KTD FILE WAS CREATED

FROM MLLW TO NAVD88; CORRECTIONS ESTABLISHED OR PUBLISHED

IN THE VICINITY OF NOAA BENCHMARKS AT SANDWICH MARINA

(CORRECTION 5.25'). NAVD88 IS ABOVE MLLW; THEREFORE,

CORRECTION SHOULD BE ADDED TO NAVD88 TO CONVERT TO MLLW.

NO TIDE GAUGES WERE USED ON THIS PROJECT. AVERAGE RANGE OF

TIDE IS 8.7' AT THE EAST END IN SANDWICH.

4. COORDINATES SHOWN ARE BASED ON THE NAD83 MASSACHUSETTS

MAINLAND ZONE 2001 DATUM AND ARE REFERENCED IN U.S. SURVEY

FEET.

5. HYDROGRAPHIC SURVEY FOR SCUSSET BORROW SITE AND CHANNEL

WAS PERFORMED USING A RESON T-50 MULTIBEAM SONAR SYSTEM

OPERATING AT 300 KHZ. HORIZONTAL POSITIONING AND REAL TIME

TIDE READINGS WERE RECORDED UTILIZING A TRIMBLE SPS 855 RTK

GPS SYSTEM. RTK BASE STATION USED WAS MTS SMARTNET MAX.

6. THE SOUNDINGS SHOWN WITHIN THE ENTRANCE CHANNEL WERE

OBTAINED FROM HYDROGRAPHIC SURVEYS CONDUCTED BETWEEN

MARCH 2022 AND JUNE 2022.

7. THE SOUNDINGS SHOWN WITHIN THE SCUSSET BORROW SITE WERE

OBTAINED FROM A HYDROGRAPHIC SURVEY CONDUCTED IN

NOVEMBER 2023.

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 4981; EAST ENTRANCE CHANNEL AND SCUSSET

BORROW SITE SURVEYED BY: MATTHEW O'NEILL AND CREW

10. AIDS TO NAVIGATION WHEN SHOWN ARE LOCATED DURING SURVEY

OPERATIONS AND ARE PLOTTED AT THE FIELD-DETERMINED

POSITIONS. THE USCG IS THE AUTHORITATIVE SOURCE OF AIDS TO

NAVIGATION. ADDITIONAL INFORMATION ON PUBLISHED LOCATIONS

AND DETAILS CAN BE FOUND IN THE USCG LIGHT LIST, VOLUME 1.

11. AERIAL IMAGERY SHOWN ON THESE DRAWINGS IS FROM 2022 AND

WAS OBTAINED BY NOAA'S NATIONAL GEODETIC SURVEY (NGS)

REMOTE SENSING DIVISION. THE IMAGERY SHOWN ON THESE

DRAWINGS ARE FOR GENERAL INFORMATION ONLY AND IS NOT TO BE

USED FOR MEASUREMENTS.

12. LIMITS OF EELGRASS SHOWN IS FROM 2023 DATA PROVIDED BY

WOODS HOLE GROUP. THE LIMITS OF INTERTIDAL ROCKY HABITAT IS

FROM 2018 DATA.

13. UNLESS OTHERWISE APPROVED, THE SUBMERGED HYDRAULIC

PIPELINE SHALL CROSS THE CHANNEL AT STATION -30+00. REFER TO

SPECIFICATION SECTION 35 20 23 (DREDGING AND DREDGED MATERIAL

PLACEMENT) FOR ADDITIONAL REQUIREMENTS FOR CROSSING THE

FEDERAL NAVIGATION CHANNEL.

14. HYDRAULIC PIPELINE SHALL NOT CROSS OVER OR COME WITHIN 75

FEET OF ANY EELGRASS. BOOSTER PUMP(S) SHALL NOT BE PLACED IN

EELGRASS OR COME WITHIN 75 FEET OF ANY EELGRASS.
