About this file
This set of construction drawings and specifications outlines requirements for the maintenance dredging of Newburyport Harbor in Newburyport, Massachusetts. Approximately 220,000 to 250,000 cubic yards of sandy material will be hydraulically dredged from the 15-foot and 9-foot channels and pumped via pipeline to an adjacent beach disposal site. The U.S. Army Corps of Engineers is soliciting bids under solicitation number W912WJ22B0011 to complete this work, which involves dredging sections of the federally maintained entrance channel and inner harbor channel to their authorized depths.

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. SOUNDINGS NOTED WITH A (+)
ARE ABOVE THE REFERENCE PLANE OF MLLW. SOUNDINGS WITHOUT A SIGN ARE BELOW THE
REFERENCE PLANE OF MLLW, AND SHOULD BE CONSIDERED NEGATIVE.
2. PLAN VIEW FEATURES SHOWN ARE FROM PREVIOUS SURVEYS, AERIAL IMAGERY AND/OR
NOAA CHART NO. 13282. ALL PLAN VIEW FEATURES, INCLUDING SHORELINE, BRIDGES, PIERS, ETC., IS LOCATED APPROXIMATE UNLESS OTHERWISE NOTED AND SHOULD BE USED AS A
GENERAL REFERENCE ONLY.
3. BENCHMARK DATA (TOPOGRAPHY) SURVEY: FOR ELEVATIONS ABOVE 0.00 MLLW IN THIS
PROJECT, THE MLLW TO NAVD88 CORRECTION IS 5.24.
BENCHMARK DATA (BATHYMETRIC): TIDES WERE RECORDED USING RTK GPS. FOR
ELEVATIONS BELOW 0.00 MLLW IN THIS PROJECT, THE MLLW TO NAVD88 CORRECTION IS 5.30
FEET AT THE ENTRANCE CHANNEL TO 4.21 AT THE INNER HARBOR. THE CORRECTION IS
REFERENCED FROM NOAA'S V-DATUM MODEL IN THE VICINITY OF NEWBURYPORT HARBOR,
MASSACHUSETTS. NAVD88 IS ABOVE MLLW; THEREFORE THE CORRECTION SHOULD BE
ADDED TO NAVD 88 TO CONVERT TO MLLW. NO TIDE GAUGES WERE USED ON THIS PROJECT.
THE AVERAGE RANGE OF TIDE IS 8.0 FEET.
4. COORDINATES SHOWN ARE BASED ON THE TRANSVERSE MERCATOR GRID SYSTEM FOR
THE STATE OF MASSACHUSETTS (MAINLAND ZONE), NAD 1983 AND ARE BASED ON U.S.
SURVEY FEET.
5. HYDROGRAPHIC SURVEY WAS PERFORMED USING A RESON T-50 MULTIBEAM SONAR
SYSTEM OPERATING AT 400 KHZ. HORIZONTAL POSITIONING AND REAL TIME TIDE READINGS
WERE RECORDED UTILIZING A TRIMBLE SPS 855 GPS SYSTEM. THE RTK BASE STATION USED
WAS STATION “RAMP (2009)”.
6. THE SOUNDING AND TOPOGRAPHIC INFORMATION SHOWN ON THESE MAPS REPRESENTS
THE SHOALEST SOUNDINGS OF THOSE OBTAINED FROM HYDROGRAPHIC AND TOPOGRAPHIC
SURVEYS CONDUCTED DURING MARCH 2021 FOR THE 9-FOOT CHANNEL AND FEBRUARY 2022
FOR THE 15-FOOT CHANNEL. THE DATA DEPICTED ON THESE MAPS SHOULD NOT BE USED
FOR VOLUME CALCULATION PURPOSES.
7. THE INFORMATION DEPICTED ON THESE PLANS REPRESENTS THE RESULTS OF SURVEYS
MADE ON THE DATES INDICATED, AND CAN ONLY BE CONSIDERED AS INDICATING THE
CONDITIONS EXISTING AT THAT TIME.
8. AIDS TO NAVIGATION WERE LOCATED DURING SURVEY OPERATIONS AND ARE PLOTTED AT
THE FIELD-DETERMINED POSITIONS AT THAT TIME. THE USCG IS THE AUTHORITATIVE SOURCE
OF AIDS TO NAVIGATION. ADDITIONAL INFORMATION ON BUOY LOCATIONS AND DETAILS CAN
BE FOUND IN THE USCG LIGHT LIST, VOLUME 1.
9. THE BEACH ACCESS FROM THE STORAGE/STAGING AREA TO THE BEACH FILL SITE
REQUIRES THE REMOVAL OF TIMBER POSTS WITH ROPE RAILS. CAREFULLY REMOVE,
PROPERLY STOCKPILE THE POSTS AND ROPE RAIL THEN REINSTALL AT THE COMPLETION OF
CONSTRUCTION. TIMBER MATS, AT LEAST 4-INCHES THICK, SHALL DEPLOYED FOR
TRAVERSING THE SENSITIVE DUNE AREA ALONG THE PATH INDICATED. REPLANT ALL DUNE
GRASS IMPACTED WITHIN THE DESIGNATED ACCESS PATH IN ACCORDANCE WITH
SPECIFICATION SECTION 32 93 00. NO EQUIPMENT OR PERSONNEL ARE PERMITTED TO
TRAVERSE THE VEGETATED DUNE AREA OUTSIDE OF THE DESIGNATED PATH. DAMAGES TO
DUNE GRASS OUTSIDE OF THE DESIGNATED PATH WIDTH SHALL BE RESTORED BY THE
CONTRACTOR AT NO ADDITIONAL EXPENSE TO THE GOVERNMENT. TIMBER MATS SHALL BE
INSTALLED IN A MANNER TO PREVENT THEM FROM FLOATING/MOVING DURING HIGH WATER
LEVEL EVENTS, OR ALTERNATIVELY REMOVED AND REINSTALLED AS NECESSARY.

SHEET NOTES:
1. THIS SHEET PRESENTS THE DREDGE MATERIAL DISPOSAL AT THE PLUM ISLAND BEACH.
2. BEACH FILL SLOPES SHALL BE CONSTRUCTED TO THE SLOPES SHOWN ON THIS SHEET. IN
NO CASE SHALL THE SIDE SLOPES BE STEEPER THAN 1 VERTICAL: 10 HORIZONTAL (1V:10H).
3. BEACH FILL ACTIVITIES SHALL BEGIN AT THE SOUTHERNMOST LANDWARD EDGE OF THE FILL
AREA SHOWN, AND PROCEED TOWARDS THE SEAWARD TOE AND ALONG THE CONTROL LINE
TO THE NORTHWEST. REFER TO SPECIFICATIONS SECTION 35 20 25 FOR ADDITIONAL BEACH
FILL REQUIREMENTS.
4. NOTE THAT THE FOOTPRINT OF THE BEACH FILL SHOWN ON THIS SHEET REFLECTS THE
TOTAL REQUIRED AND ALLOWABLE OVERDEPTH VOLUMES PRESENTED IN THE BIDDING
SCHEDULE FOR BOTH THE 15-FOOT AND 9-FOOT CHANNELS (APPROX. 257,000 CY). THE
FINAL FILL MAY VARY FROM WHAT IS SHOWN, DEPENDING ON THE ACTUAL VOLUME OF
BEACH MATERIAL DREDGED. CONSTRUCTION OF THE BEACH FILL BERM SHALL NOT
ADVANCE ALONG THE CONTROL LINE UNTIL THE TARGET BERM CREST WIDTH, ELEVATION,
AND REQUIRED FILL SLOPES HAVE BEEN ACHIEVED AT ANY GIVEN STATION. FILL SHALL
START AT STATION 0+00 AND PROCEED NORTHWEST ALONG THE CONTROL LINE.
COORDINATE WITH THE COR, FIELD ADJUST, AND PROCEED WITH FILL ALONG THE BEACH AS
NEEDED BASED ON ACTUAL DREDGE MATERIAL QUANTITIES REMOVED FROM THE CHANNEL
DURING CONSTRUCTION.
5. FLOOD CONTROL MEASURES WERE INSTALLED TO PROTECT THE HOUSES ADJACENT TO
THE WORK SITE. FLOOD CONTROL MEASURES ARE TO BE REMOVED BY OTHERS PRIOR TO
THE START OF THE CONTRACT WORK. IF THESE MEASURES ARE STILL IN PLACE AT THE
START OF WORK, COORDINATE WITH THE COR.
