AREAS AND REQUIREMENTS.

7. THE PROPOSED DESIGN ELEVATION OF THE JETTY WAS DERIVED FROM RECORD INFORMATION.

8. THE CONTRACTOR SHALL PHOTO DOCUMENT THE EXISTING STATE NORTH JETTY AND TOWN ROCKS WITHIN THE LIMITS OF WORK PRIOR TO THE

START OF CONSTRUCTION. THE CONTRACTOR SHALL NOT PLACE EQUIPMENT ON THE JETTY STRUCTURE AND SHALL NOT DAMAGE THE EXISTING

STATE NORTH JETTY AND TOWN ROCKS. ANY DAMAGE CAUSED BY THE CONTRACTOR SHALL BE FIXED AT THE CONTRACTOR'S EXPENSE.

9. CONSTRUCTION WINDOWS FOR LAND AND WATER BASED WORK DIFFER BASED ON ENVIRONMENTAL RESTRICTION. REFER TO SPECIFICATION

SECTION 01 11 00 SUMMARY OF WORK FOR DETAILS ON TIME OF YEAR RESTRICTIONS.

10. ARMOR STONE INSTALLED IN THE REPAIR AREA MAY VARY IN ELEVATION FROM THE DESIGN GRADE, IN ACCORDANCE WITH SPECIFICATION SECTION

35 31 19. VARIATIONS IN THE FINISHED GRADE WITHIN THE TOLERANCES STATED IN THE SPECIFICATIONS SHALL BB ACCEPTED AS THE REQUIRED

FINISHED CREST ELEVATION.

11. UNLESS OTHERWISE NOTED, ALL EXISTING ARMOR STONES OUTSIDE OF THE REPAIR AREA THAT INTERFACE WITH NEW OR RESET ARMOR STONES

SHALL BE ADJUSTED, AS NECESSARY, TO PROVIDE FOR MAXIMUM INTERLOCKING BETWEEN THE REPAIR AND NON-REPAIR AREAS. PLACEMENT OF

ARMOR STONE AND THE READJUSTMENT OF EXISTING STONES SHALL BE IN ACCORDANCE WITH SPECIFICATION 35 31 19.

12. DURING CONSTRUCTION, ALL INCOMPLETE REPAIR AREAS MUST BE SECURED TO PREVENT MATERIAL LOSS AND/OR MATERIAL MIGRATION INTO THE

WATER DURING TIDAL CYCLES AND STORMS. DAMAGES TO INCOMPLETE WORK AREAS SHALL BE REPAIRED AT THE CONTRACTOR'S EXPENSE.

ARMOR STONE AND UNDERLAYER STONE TO THE MINIMUM DEPTHS REQUIRED TO PLACE NEW

UNDERLAYER STONE AND 6-10 TON ARMOR STONE. REPAIR SHALL EXTEND TO A MINIMUM DEPTH OF

TWO ARMOR STONES (9 FT) AND TWO LAYERS OF UNDERLAYER STONE (51 IN) FOR A TOTAL OF 13.25 FT

BELOW CREST HEIGHT.

2. REMOVAL OF ARMOR STONE ALONG THE SIDE SLOPES SHALL BE FROM THE TOP OF THE SLOPE AT THE

CREST TO THE TOES OF THE REPAIR LIMIT. ON THE OCEAN SIDE OF THE JETTY, THE REPAIR LIMIT

SHALL EXTEND TO EXISTING GRADE JUST BEYOND THE STRUCTURE LIMITS. ON THE CHANNEL SIDE OF

THE JETTY, THE REPAIR LIMIT SHALL EXTEND, AT A MINIMUM, TO ELEVATION -1' SUCH THAT 9' OF

ARMOR STONE AND 51" OF UNDERLAYER STONE CAN BE PLACED. THE REPAIR AREA TOE OF SLOPE

SHALL BE SET AT THE LOCATION WHERE THE EXISTING ARMOR STONES ARE NO LONGER DISPLACED

OR LOOSE AND THE EXISTING ARMOR STONES PROVIDE A BASE WHERE THE STONES ARE STABLE, WELL INTERLOCKED, AND ALL FACES OF EXISTING ARMOR STONES ARE IN CONTACT WITH ADJACENT

ARMOR STONE. SEE NOTE 4 ON C-101.

3. PLACE NEW UNDERLAYER STONE AS NEEDED TO MEET REQUIRED DEPTH OF UNDERLAYER AND

ARMOR STONE OUTLINED IN NOTE 1. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO PROTECT AND

MAINTAIN THE REQUIRED UNDERLAYER GRADES PRIOR TO PLACEMENT OF ARMOR STONE. ANY

REWORK REQUIRED DUE TO WEATHER, TIDES, OR OTHER EXPOSURE SHALL BE THE RESPONSIBILITY

OF THE CONTRACTOR. ALL UNDERLAYER STONE INSTALLED SHALL BE COVERED BY ARMOR STONE.

4. AFTER A SECTION OF NEW UNDERLAYER STONE HAS BEEN ADDED, REBUILD THE JETTY BY SETTING

EXISTING AND/OR NEW ARMOR STONE AT THE CREST AND ALONG THE SIDE SLOPES. ARMOR STONE

SHALL BE PLACED AND INTERLOCKED PER SPEC SECTION 35 31 19, PARAGRAPH 3.6.3 "PLACEMENT OF

ARMOR STONE".

5. REUSE ALL EXISTING ARMOR STONE IN ACCORDANCE WITH SPEC SECTION 35 31 19, PARAGRAPH 3.5

"REUSE OF EXISTING STONE."

6. THE CONTRACTOR SHALL ADD NEW 6-10 ARMOR STONES AS NEEDED. THE NUMBER OF ARMOR STONES

ADDED SHALL BE SUFFICIENT TO MEET THE REQUIRED FINISHED CREST ELEVATION AND SIDE SLOPES.

7. THE NEW JETTY TOE ON THE SEAWARD SIDE OF THE JETTY SHALL BE CONSTRUCTED USING REUSED

3-4 TON ARMOR STONES EXCAVATED FROM THE JETTY WITHIN THE REPAIR AREA. ANY STONES

GREATER THAN 4 TONS BUT LESS THAN 6 TONS MAY ALSO BE INCORPORATED INTO THE TOE IF

ENCOUNTERED. STONES SHALL BE PLACED A MINIMUM OF TWO WIDE AND WITHIN THE LIMITS SHOWN

ON THE PLAN AND SECTION VIEWS ALONG THE LENGTH OF THE REPAIR AREA. SHOULD THE AMOUNT OF

REUSED 3-4 TON STONE BE INSUFFICIENT TO CONSTRUCT THE ENTIRE TOE, NEW 3-4 TON ARMOR

STONE SHALL BE USED TO COMPLETE CONSTRUCTION. REFER TO SPECIFICATION 35 31 91 SUBPART

General Notes

Project Remarks High shoaling in the 8-Foot Seabrook Reach prevented full coverage of the area.

The sounding information shown on this map represents the SHOALEST soundings of those obtained from hydrographic surveys conducted during December 2022. The positions of aids to navigation were located during survey operations, are provided for information only and should not be used for navigation. Orthoimagery is from a variety of sources and dates and is intended to portray general characteristics of the shoreline and other features. Temporal changes may have occurred since this dataset was collected and some parts may no longer be an accurate representation of the conditions. The information depicted on this map should NOT be used to determine volumes as volumes are determined from more sounding information than shown.

Tides were recorded using RTK GPS. The MLLW to NAVD88 correction for this project ranged from 5.19 to 5.21 feet. This correction is referenced from NOAA's V-Datum Model Version 4.0, ME/NH/MA Region Version 2.3, in the vicinity of Hampton Harbor, Hampton, NH. NAVD88 is above MLLW; therefore the correction should be added to NAVD88 to convert to MLLW. No tide gauges were used on this project.
