GENERAL NOTES:

3) INTERIOR WEIRS MAY BE CONSTRUCTED IF DESIRED BY THE CONTRACTOR, AND

SHALL BE INCLUDED IN THE DISPOSAL PLAN FOR APPROVAL BY THE COR. WEIRS,

IF CONSTRUCTED BY THE CONTRACTOR SHALL NOT EXCEED ELEVATION +2.5 NAVD88.

6) LENGTHS OF RETENTION DIKE TANGENTS AS SHOWN ON DRAWING C-01

ARE APPROXIMATE AND WILL BE FIELD VERIFIED.

5) UNDISTURBED PLUGS/NATURAL CROSSINGS AT LEAST EVERY 500 FEET ARE

REQUIRED IN ANY BORROW PITS FOR THE PERIMETER RETAINING DIKES TO

PREVENT EROSIVE CHANNELING BY THE EFFLUENT WATERS ALONG THE

DIKES AND TO INCREASE RETENTION TIME. THE DISCHARGE LINE INTO THE

DISPOSAL AREA SHALL HAVE MANIFOLDS OR BAFFLES ON THE POINT DISCHARGE.

1) THE CONTRACTOR WILL BE RESPONSIBLE FOR CONTAINING ALL DREDGED

MATERIAL WITHIN THE BOUNDARIES OF THE RESTORATION AREA. RETENTION

DIKES ARE REQUIRED TO RETAIN THE MATERIAL WITHIN THE RESTORATION

BOUNDARIES, AND SHALL BE CONSTRUCTED FROM IN-SITU MATERIAL

OBTAINED FROM WITHIN THE MARSH CREATION BOUNDARY. BORROW MATERIAL

SHALL BE TAKEN AT LEAST 55 FEET FROM THE CENTERLINE OF THE RENOVATED

DIKES. PERIMETER RETENTION DIKES SHALL BE CONSTRUCTED WITH A MINIMUM

5' CROWN WIDTH TO ELEVATION +4.5 NAVD88, EXCEPT FOR THE APPROXIMATE

1000' REACH ADDRESSED IN NOTE 2. SEE THEORETICAL DIKE SECTION PROVIDED

ON DRAWING C-06.

12) THE ALLOWABLE BORROW PIT POLYGON AND COORDINATES DEFINED ON

DRAWING C-03 REPRESENT THE ULTIMATE TOP EDGE OF CUT. IF A BOX

CUT IS IMPLEMENTED, IT SHALL ACCOUNT FOR ALL EXCAVATION REMAINING

WITHIN THIS DEFINED BOUNDARY. AT NO TIME SHALL EXCAVATION FOR

BORROW BE PERFORMED OUTSIDE THIS ALLOWABLE BOUNDARY.

16) PLANVIEW BACKDROPS WERE FROM PHOTOGRAPHY DATED 2010.

11) THE CONTRACTOR SHALL ESTABLISH A GRID OF STAFF GAGES WITHIN THE

MARSH CREATION FOOTPRINT AS SHOWN ON DRAWING C-04. STAFF GAGES

SHALL CONSIST OF 3 INCH PVC PIPE OR 4 INCH BY 4 INCH WOODEN POSTS,

MARKED AT HALF FOOT INTERVALS.

10) EFFLUENT WEIRS OR SPILL BOXES SHALL BE CONSTRUCTED AND MAINTAINED

TO MANAGE EFFLUENT WATER LEVELS, WHICH SHALL NOT EXCEED

ELEVATION +3.5' NAVD88. THESE STRUCTURE(S) SHALL BE LOCATED IN THE

NORTH AND/OR WEST RETENTION DIKES. THE CONTRACTORS PLAN FOR

MANAGING EFFLUENT WATER ELEVATIONS SHALL BE INCLUDED IN THE

DISPOSAL OF DREDGE MATERIAL PLAN.

15) COORDINATES SHOWN ON THESE DRAWINGS REFERENCE STATE PLANE,

NAD 83, LOUISIANA SOUTH ZONE 1702, U.S. SURVEY FEET.

13) THE PRIMARY BORROW PIT SHALL BE EXHAUSTED TO THE SATISFACTION

OF THE COR PRIOR TO RELOCATING TO THE SECONDARY BORROW PIT

FOR EXCAVATION. EXCAVATION SHALL BE MONITORED BY BEFORE AND

AFTER DREDING CROSS SECTIONS (SEE NOTE 4 ON DRAWING C-05).

14) THE NOAA NAUTICAL CHART REFERENCED IN PARAGRAPH 3.2.2 OF

SECTION 35 20 23.00 12 OF THE SPECIFICATIONS INDICATE AN AUTHORIZED

CLEARANCE OF 40 FEET AT THE ENTERGY OVERHEAD TRANSMISSION LINE

SHOWN ON THE CONTRACT PLAN DRAWINGS. THE CONTRACTOR SHALL

COORDINATE CROSSING UNDER THIS AERIAL TRANSMISSION LINE TO

ASSURE SAFE ACCESS. ALL EFFORTS SHOULD BE MADE TO ACCESS UNDER

THESE LINES WITHOUT REQUIRING THE LINES TO BE DE-ENERGIZED, OR TO

MINIMIZE DOWNTIME. THE CONTRACTOR SHALL PROVIDE THE UTILITY

OWNER A MINIMUM OF SIX (6) WEEKS LEAD TIME PRIOR TO ACCESSING THE

UTILITY CROSSING(S).

17) ALL ELEVATIONS ARE IN SURVEY FEET AND IN NORTH AMERICAN

VERTICAL DATUM 1988 (NAVD88), 2006.81 EPOCH. SURVEY DATA SHOWN IN

PLAN AND CROSS SECTION VIEWS WERE TAKEN IN MARCH 2012. THE

ELEVATIONS IN THESE PLANS AND SPECIFICATIONS ARE BASED OFF OF THE

FOLLOWING MONUMENTATION ESTABLISHED IN USACE SURVEYJOB# 12-055C.

2) THE SOUTHERN BORDER OF THE MARSH CREATION FOOTPRINT CONTAINS AN

APPROXIMATE 1000' REACH OF SHORELINE BREACH, ALLOWING LAKE WATERS

TO ENTER THE PROPOSED MARSH CREATION SITE. THIS REACH SHALL BE

REPAIRED WITH AN EARTHEN SECTION TO MINIMUM ELEVATION +4.5' NAVD88 HAVING A

MINIMUM 20' CROWN WIDTH AND 1 VERTICAL ON 4 HORIZONTAL INTERIOR SIDE SLOPES, AND

1 VERTICAL ON 3 HORIZONTAL SIDE SLOPES LAKE SIDE TO ACCOMODATE EROSION

CONTROL GEOTEXTILE BAG PLACEMENT. THIS REACH OF SHORELINE RESTORATION

SHALL BE PROTECTED WITH A LAYER OF EARTHEN FILLED GEOTEXTILE BAGS.

FURTHER INFORMATION ON THIS PROTECTION MEASURE CAN BE FOUND IN THE

SPECIFICATION SECTION "EROSION CONTROL". REFERENCE THEORECTICAL

SHORELINE RESTORATION SECTIONS PROVIDED ON DRAWING C-06.

4) EXISTING RETENTION FEATURES RESIDE ON THE EASTERN, WESTERN,

AND PARTIAL SOUTHERN BOUNDARIES OF THE MARSH CREATION SITE

WHICH MAY BE ADEQUATE FOR RETENTION OF DREDGED MATERIAL, OR

MAY REQUIRE REHABILITATION BY THE CONTRACTOR PRIOR TO DREDGING.

ANY VEGETATIVE OR WOODY DEBRIS CLEARED FROM THESE EXISTING

FEATURES MAY BE DISPOSED OF WITHIN THE MARSH CREATION SITE AND

BURIED DURING THE FILLING OPERATION.

7) THREE (3) ACCESS CORRIDORS ARE AVAILABLE FOR USE BY THE CONTRACTOR.

THE WESTERN 200' WIDE "PIPELINE CORRIDOR" IS FOR PIPELINE ACCESS TO THE

MARSH CREATION SITE. NO EXCAVATION WITHIN THIS CORRIDOR IS ALLOWED.

THE SECOND "EXTERIOR ACCESS CORRIDOR" ALLOWS FOR EXCAVATION TO A 60'

BOTTOM WIDTH, NOT TO EXCEED ELEVATION -6.0 NAVD88. MATERIAL EXCAVATED MAY BE

STOCKPILED AS SHOWN ON DRAWING C-019. DISPOSAL AREAS WEST OF THE EXISTING

BREAKWATER SHALL BE BACKFILLED INTO THE CORRIDOR PRIOR TO DEMOBILIZATION.

THIS CORRIDOR SHALL BE USED FOR ACCESS TO THE SHORELINE RESTORATION

SITE, OFFLOADING EQUIPMENT, AND MATERIALS. THE "INTERIOR ACCESS CANAL" MANDATES

EXCAVATION TO -5.0' NAVD88 BY 35 FOOT BOTTOM WIDTH. DISPOSAL IS EAST OF THE EXISTING

BREAKWATER. THE EXISTING NAVIGATION CANAL PARALLELING THE EASTERN BOUNDARY OF THE MARSH

CREATION SITE MAY BE USED TO THE LIMITS INDICATED ON THE DRAWINGS FOR TRANPORT OF PERSONNEL

AND SUPPLIES, BUT AT NO TIME SHALL LOCAL WATERWAY TRAFFIC BE OBSTRUCTED.

9) BORROW DEPTH WITHIN LAKE PONTCHARTRAIN HAS BEEN ESTABLISHED AT

ELEVATION -19.0' NAVD88, WITH ALLOWABLE 1' OVERDEPTH TO -20.0 NAVD88.

EXCAVATION SHALL AT NO TIME EXCEED ELEVATION -20.0' NAVD88.

18) A CULTURALLY SIGNIFICANT SITE IS INDICATED ON THE DRAWINGS WITHIN LAKE

PONTCHARTRAIN. THE CONTRACTOR SHALL MINIMIZE IMPACTS BY AVOIDANCE OF THIS AREA.

8) FLOTATION EXCAVATION IS ALLOWED ADJACENT TO AND ALONG THE LENGTH OF THE

SHORELINE RESTORATION FEATURE. ALLOWABLE EXCAVATION SHALL NOT EXCEED

60 FEET IN WIDTH AT ELEVATION -6.0 NAVD88. MATERIAL EXCAVATED SHALL BE USED

IN THE CONSTRUCTION OF A BASE PLATFORM FOR THE SHORELINE RESTORATION FEATURE,

OR AS FILL MATERIAL FOR THE EXISTING INTERIOR BORROW DITCH, OR STOCKPILED LAKESIDE

TO BE BACKFILLED INTO FLOTATION CHANNEL POST CONSTRUCTION.
