EROSION CONTROL SEQUENCE
PHASE 1
PROCEED AS FOLLOWS:
1. HOLD PRE —CONSTRUCTION MEETING TO
IDENTIFY SITE CONSTRAINTS, CONSTRUCTION
ROUTING, AND STAGING.
2. INSTALL CONSTRUCTION ENTRANCE AND
CONSTRUCTION ACCESS.
3. INSTALL PERIMETER EC MEASURES AROUND
AREAS TO BE DEMO—ED, INCLUDING SILT
FENCE.
4. BREAK AND REMOVE HARD SURFACE AS
NEEDED TO INSTALL ACCESS TO RIVER.
5. CUT ACCESS ROAD TO BUILD WAVE AND HAUL
OFF MATERIAL.
6. CLEAR AND GRUB ONLY AREAS ADJACENT TO
WAVE CONSTRUCTION ACCESS.
7. ENSURE A STABLE AND VEGETATED SURFACE
BEFORE MOVING TO THE NEXT PHASE OF
WORK. LEAVE EROSION CONTROL MEASURES IN
PLACE UNTIL FINISHED SURFACE TREATMENT IS
APPLIED.
8. MAINTAIN EROSION CONTROL DEVICES AS
NOTED IN EC AND WHITEWATER PACKAGE
DETAILS.
9. INSTALL ADDITIONAL MEASURES AS NEEDED TO
KEEP SEDIMENT ON SITE.

SUGGESTED WATER CONTROL METHOD AND CONSTRUCTION PHASING SEQUENCE
TO COMPLETE THE IN -STREAM WORK SCOPE. THFo CONTRACTOR IS RESPONSIBLE
FOR SUBMITTING A WATER CONTROL PLAN, INST LING AND MAINTAINING WATER
CONTROL IN A SAFE CONDITION BASED ON ACTUAk SITE CONDITIONS.
CONTRACTOR WATER CONTROL PLAN SHALL BE S BMITTED TO ENGINEER FOR
REVIEW AND APPROVAL BY PERMITTING AGENCIES.
NOTE 2: THE WEATHER FORECAST SHOULD BE MONO ORED CLOSELY PRIOR TO
AND DURING ALL IN -STREAM WORK. IT IS ESSENTIAL HAT CONCRETE PLACEMENTS
BE COMPLETED DURING LOW FLOW WINDOWS AND F LLOWED BY SEVERAL DAYS
OF LOW FLOWS TO ENSURE DRY CONDITIONS FOR CURING.
NOTE 3: THE CONTRACTOR IS RESPONSIBLE FOR SUBMITTING A HIGH WATER
CONTINGENCY PLAN. THIS PLAN SHOULD OUTLINE HO THE JOBSITE WILL BE
SECURED IN THE EVENT OF RISING WATER LEVELS INCL DING HOW TO
EFFICIENTLY REMOVE PERSONNEL, MATERIALS AND EQUIPMENT FROM THE

EROSION CONTROL SEQUENCE
PHASE 7
PROCEED AS FOLLOWS:
1. INSTALL EC MEASURES AROUND AREAS TO BE
DEMO-ED, INCLUDING SILT FENCE ADJACENT
TO PUT -IN WORK AREA.
2. BREAK AND REMOVE HARD SURFACE AS
NEEDED TO INSTALL ACCESS TO RIVER.
3. CUT ACCESS ROAD TO BUILD RIVER PUT -IN
AREA.
4. CLEAR AND GRUB ONLY AREAS ADJACENT TO
WAVE CONSTRUCTION ACCESS.
5. MAINTAIN EROSION CONTROL DEVICES AS
NOTED IN EC AND WHITEWATER PACKAGE
DETAILS.
6. INSTALL ADDITIONAL MEASURES AS NEEDED TO
KEEP SEDIMENT ON SITE.
7. INSTALL COFFERDAM FOR WATER CONTROL _
SURROUNDING PUT -IN WORK ZONE USING
SUPER SACK CONSTRUCTION DETAIL PROVIDED
IN WHITEWATER PLAN SET. SUPER SACKS TO
BE FILLED WITH GRAVEL OR SMALL COBBLE
BASED ON CONTRACTOR PREFERENCE.
8. INSTALL PUT -IN AREA BANK PROTECTION AND
BEACH AREA.
9. REMOVE ALL EQUIPMENT AND MATERIALS FROM
THE RIVER. REMOVE THE TEMPORARY ACCESS
ROADS TO THE PUT -IN AREA AND TO THE
WAVE AREA.
10. ENSURE A STABLE AND VEGETATED SURFACE
BEFORE MOVING TO THE NEXT PHASE OF
WORK. COORDINATE REMOVAL OF ACCESS
ROADS WITH UPLAND SCOPE OF WORK. SEE
EQUINOX DRAWING SET.

COFFERDAM NOTES:
(1) WRAP "SUPER SACKS" WITH IMPERVIOUS PLASTIC LINER TO PREVENT SEEPAGE.
(2) BACKFILL THE DOWNSTREAM SIDE OF THE COFFERDAM WITH NATIVE ADJACENT ALLUVIUM.
(5) USE "SUPER SACKS" AS A BUTTRESS AS REQUIRED.

GENERAL EROSION & SEDIMENT CONTROL NOTES:
(1) THE IMPLEMENTATION OF EROSION AND SEDIMENT CONTROL MEASURES
AND BEST MANAGEMENT PRACTICES INCLUDING CONSTRUCTION,
MAINTENANCE, REPLACEMENT AND UPGRADING ARE THE RESPONSIBILITY OF
THE CONTRACTOR UNTIL ALL CONSTRUCTION IS COMPLETED AND
APPROVED.
(2) THE DETAILS SHOWN ON THIS SHEET ARE AN EXAMPLE OF ACCEPTABLE
METHODS TO USE DURING CONSTRUCTION OF THIS PROJECT. THE
CONTRACTOR IS RESPONSIBLE FOR DEVELOPING AND SUBMITTING A
COFFERDAM PLAN TO INCLUDE SUFFICIENT DETAIL OF MEANS AND
METHODS SATISFACTORILY MEETING THE PROJECT SPECIFICATIONS AND
PERMIT REQUIREMENTS. COFFERDAMS MAY CONSIST OF OTHER METHODS
INCLUDING (BUT NOT LIMITED TO) SECLUSION FENCING, SAND BAGS, BULK
BAGS, SUPER SACKS, SHEET PILE AND INFLATABLE BLADDERS.
COFFERDAMS SHALL INCLUDE PLASTING LINER OR FINE MESH SILT FENCE
TO REDUCE TURBIDITY AND FINES FROM ENTERING THE FREE FLOWING
PORTION OF LIVE WATER.
(5) ALL PUMP INTAKES SHALL BE SCREENED FOR FISH PROTECTION AS
REQUIRED BY REGULATORY AGENCIES.
(4) DEWATERING PUMP DISCHARGE FROM WITHIN COFFERDAM WORK AREAS
SHALL BE RELEASED ONTO FLOODPLAIN AREAS AWAY FROM WETLANDS AND
CONSTRUCTION ACTIVITIES. DISCHARGE SHALL NOT CAUSE EROSION OF
TOPSOIL AND SHALL SHEET FLOW OVER THE FLOODPLAIN BEFORE
RETURNING TO LIVE WATER DOWNSTREAM OF THE WORK AREA. ALL
RETURN FLOWS MUST MEET PERMIT REQUIREMENTS FOR TURBIDITY.
(5) ALL EARTHWORK AND WOOD STRUCTURES CONSTRUCTION WITHIN THE
ORDINARY HIGH CHANNEL SHALL CONFORM TO WATER QUALITY STANDARDS
ESTABLISHED BY THE REGULATORY AGENCY PERMITS FOR THIS PROJECT.
