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 (+) ARE ABOVE THE REFERENCE PLANE OF MLLW. ANY

SOUNDINGS WITHOUT A SIGN ARE BELOW THE REFERENCE PLANE OF MLLW, AND

SHOULD BE CONSIDERED NEGATIVE.

2. TOPOGRAPHY SHOWN IS FROM PREVIOUS SURVEYS AND/OR NOAA CHART NO.

13283. ALL TOPOGRAPHY, INCLUDING SHORELINE, BRIDGES, PIERS, ETC., IS

LOCATED APPROXIMATE UNLESS OTHERWISE NOTED AND SHOULD BE USED AS A

GENERAL REFERENCE ONLY.

3. BENCH MARK DATA: TIDES WERE RECORDED USING RTK GPS. THE MLLW TO

NAVD88 CORRECTION FOR THIS PROJECT IS 5.10 FEET. THE CORRECTION IS

REFERENCED FROM NOAA'S V-DATUM MODEL IN THE VICINITY OF RYE HARBOR,

RYE, NEW HAMPSHIRE. NAVD88 IS ABOVE MLLW, THEREFORE THE CORRECTION

SHOULD BE ADDED TO NAVD88 TO CONVERT TO MLLW. NO TIDE GAUGES WERE

USED ON THIS PROJECT. AVERAGE RANGE OF TIDE IS 8.4 FEET.

4. COORDINATES SHOWN ARE BASED ON THE TRANSVERSE MERCATOR GRID SYSTEM

FOR THE STATE OF NEW HAMPSHIRE (ZONE 2800), NAD 1983 AND ARE BASED ON

U.S. SURVEY FEET.

5. SURVEY WAS PERFORMED USING A RESON T-50 SONAR SYSTEM OPERATING AT

400 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 FISH PIER (2020).

6. THE SOUNDING INFORMATION SHOWN IN THE CONTRACT DRAWINGS

REPRESENTS THE SHOALEST SOUNDINGS OF THOSE OBTAINED FROM

HYDROGRAPHIC SURVEYS CONDUCTED DURING MARCH 2020.

7. THE SOUNDING INFORMATION DEPICTED IN THE CONTRACT DRAWINGS SHOULD

NOT BE USED TO DETERMINE VOLUMES. VOLUMES ARE DETERMINED FROM

MORE SOUNDING INFORMATION THAN SHOWN.

8. THE INFORMATION DEPICTED IN THE CONTRACT 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 4190

SURVEYED BY: PATRICK BERUBE AND CREW

REFER TO SURVEY NO. : RYE_2020_0319_CS_020

10.AIDS TO NAVIGATION WERE LOCATED DURING THE SURVEY OPERATIONS AND ARE

PLOTTED AT THE FIELD-DETERMINED POSITIONS. THE USCG IS THE

AUTHORITATIVE SOURCE OF AIDS TO NAVIGATION AND ADDITIONAL DETAILS CAN

BE FOUND IN THE USCG LIGHT LIST, VOLUME 1.
