GENERAL NOTES:

1. SOUNDINGS ARE IN FEET AND TENTHS. THE REFERENCE PLANE IS MEAN LOW WATER (MLW) AND IS

BASED ON THE 1983-2001 TIDAL EPOCH. ANY SOUNDINGS NOTED WITH A (+) ARE ABOVE THE REFERENCE

PLANE OF MLW. ANY SOUNDINGS WITHOUT A SIGN ARE BELOW THE REFERENCE PLANE OF MLW, AND

SHOULD BE CONSIDERED NEGATIVE.

2. TOPOGRAPHY SHOWN IS FROM A SURVEY CONDUCTED IN FEBRUARY AND MARCH OF 2020. ALL

TOPOGRAPHY, INCLUDING BEACHES, SHORELINE, 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 MLW TO NAVD88 CORRECTION FOR

THIS PROJECT IS 1.65 FEET. THE CORRECTION IS REFERENCED FROM NOAA'S V-DATUM MODEL IN THE

VICINITY OF WINNAPAUG POND, WESTERLY, RHODE ISLAND. NAVD88 IS ABOVE MLW, THEREFORE THE

CORRECTION SHOULD BE ADDED TO NAVD88 TO CONVERT TO MLW. NO TIDE GAUGES WERE USED ON

THIS PROJECT. AVERAGE RANGE OF TIDE IS 1.8 FEET.

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

RHODE ISLAND (ZONE 3800), NAD 1983 AND ARE BASED ON U.S. SURVEY FEET.

5. SURVEY WAS PERFORMED USING AN ODOM HYDROTRAC SINGLE-BEAM SONAR SYSTEM OPERATING AT

200 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 POND (2020).

6. THE SOUNDING INFORMATION SHOWN ON THE CONTRACT DRAWINGS REPRESENTS THE SHOALEST

SOUNDINGS OF THOSE OBTAINED FROM HYDROGRAPHIC SURVEYS CONDUCTED DURING FEBRUARY AND

MARCH 2020.

7. THE SOUNDING INFORMATION DEPICTED ON THE CONTRACT DRAWINGS SHOULD NOT BE USED TO

DETERMINE VOLUMES. VOLUMES ARE DETERMINED FROM MORE SOUNDING INFORMATION THAN SHOWN.

8. THE INFORMATION DEPICTED ON 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. LIMIT OF TOE FOR PLACED DREDGE MATERIAL SHOWN IS APPROXIMATE ONLY AND SHALL NOT BE USED

TO DETERMINE CONSTRUCTION LIMITS OF PLACED DREDGE MATERIAL.
