� NOTES:*example

1. THIS WORK WILL REQUIRE A DETOUR ROAD AND DIVERSION OF THE STREAM. STREAM

FLOWS MAY NOT BE PUMPED DURING CONSTRUCTION.

2. DETOUR ROAD, DIVERSION AND DEWATERING IS THE CONTRACTOR'S RESPONSIBILITY;

DETAILS ON THIS SHEET ARE PROVIDED FOR INFORMATION ONLY. THE CONTRACTOR

SHALL PROVIDE A DETAILED DIVERSION AND DEWATERING PLAN TO THE ENGINEER FOR

REVIEW PRIOR TO STARTING CONSTRUCTION. TEMPORARY DIKES OR BERMS MAY BE

CREATED TO ISOLATE THE WORK FROM WATER OF SURROUNDING AREA.

3. STREAM BASE FLOWS WILL BE BYPASSED DURING CONSTRUCTION. LARGER FLOWS

DURING PROLONGED PRECIPITATION OR SNOW MELT EVENTS WILL OVER TOP THE ROAD

OR CAUSE EXTENSIVE FLOODING OF THE SURROUNDING AREA AND CONSTRUCTION

MUST BE TIMED TO ACCOUNT FOR THESE EVENTS.

4. ROAD MAY NOT BE CLOSED TO THRU TRAFFIC DURING CONSTRUCTION. DO NOT BLOCK

ACCESS TO EXISTING RESIDENCES.

P a g e | 9

5. THE TEMPORARY DIVERSION CHANNEL SHOWN HAS BEEN DESIGNED FOR FLOWS UP TO

89 CFS (APPROXIMATELY EQUIVALENT TO THE 2 YEAR FLOOD EVENT). CONTRACTOR

SHALL PLAN FOR CONSTRUCTION TO OCCUR DURING THE DRY SEASON AFTER BREAKUP.

6. USE 10 MIL REINFORCED VISQUEEN LINER ALONG THE ENTIRE LENGTH AND WIDTH OF

TEMPORARY DIVERSION CHANNEL. DO NOT CONSTRUCT WITH LONGITUDINAL JOINTS.

BURY UPSTREAM EDGE OF LINER A MINIMUM OF 12" DEEP AND SECURE WITH RIPRAP OR

SAND BAGS.

7. CONSTRUCT TEMPORARY DIVERSION CHANNEL PRIOR TO CONSTRUCTION OF

ALUMINUM BOX CULVERT.

8. BOX CULVERT SHALL BE CONSTRUCTED IN THE DRY. PROVIDE COFFERDAM AND PUMP

HOSE AS REQUIRED TO DEWATER CONSTRUCTION AREA. ALL DISCHARGE POINTS

REQUIRE PERMANENT OR TEMPORARY VELOCITY CONTROLS. PROVIDE FOR SEDIMENT

REMOVAL FOR ALL DEWATERING ACTIVITY PRIOR TO DISCHARGE FROM THE PROJECT

INTO ANY WATER OF THE UNITED STATES.

9. PUMPS SHALL BE SIZED TO CARRY HIGHEST FLOW REASONABLY EXPECTED TO OCCUR

DURING CONSTRUCTION INCLUDING SURFACE AND SUBSURFACE FLOWS.

10.ENERGY DISSIPATOR WILL BE NECESSARY AT THE DEWATERING DISCHARGE LOCATION.

DEWATERING DISCHARGE POINT MUST BE LOCATED AT LEAST 100 FEET FROM STREAM

TO ALLOW FOR SEDIMENT REMOVAL THROUGH THE RIPARIAN VEGETATION BUFFER.

11.REMOVE DIVERSION CHANNEL AFTER STREAM FLOW HAS BEEN RE-DIVERTED TO THE

ALUMINUM BOX CULVERT. SEED ALL DISTURBED AREAS.

1.DIVERSION CULVERTS ARE TEMPORARY AND SHALL BE REMOVED AT THE END OF THE

PROJECT.

2.SUPERSACK COFFERDAM SHALL BE CONSTRUCTED OF MULTIPLE UNITS OF SUPERSACKS

FILLED WITH CLEAN GRAVEL OR COBBLE, AND ABUTTED SIDE BY SIDE TO CREATE A WATER

TIGHT BARRIER THAT SEPARATES THE CONSTRUCTION SITE FROM THE STREAM.

3.IF WATER DEPTH EXCEEDS 85% OF THE SUPER SACK HEIGHT, AN ADDITIONAL TOP ROW

OF BAGS SHALL BE INSTALLED AND SUPPORTED BY TWO BOTTOM ROWS OF SUPERSACK

BAGS.

P a g e | 10

4.THE COFFERDAM SHALL BE SEALED BY COVERING IT WITH REINFORCED PLASTIC

SHEETING THAT IS HELD IN PLACE BY ROWS OF SANDBAGS OR ROCK. INTERMITTENT

PLACEMENT OF SANDBAGS OR ROCKS WILL BE EFFECTIVE. THE SANDBAGS MUST BE

PLACED ON THE TOP OF THE SACKS AS WELL AS ALONG THE TOE OF THE COFFERDAM TO

HOLD IT IN PLACE. THE PORTION OF THE SHEETING DRAPED ONTO THE WATER SIDE OF

THE COFFERDAM SHALL BE WEIGHTED TO THE BOTTOM WITH A MINIMUM OF TWO

ROWS OF SANDBAGS.

5.THE ENDS OF THE COFFERDAM SHALL BE EXTENDED ONTO DRY LAND AND THE ENDS OF

THE POLY SHEETING SHALL BE SECURED ABOVE THE WATERLINE WITH MULTIPLE LAYERS

OF SANDBAGS. IF THE ENDS MUST BE TERMINATED AT A WET LOCATION THE COFFERDAM

SHALL BE TIGHTLY SEALED TO THE GROUND WITH MULTIPLE LAYERS OF SHEETING AND

SANDBAGS.

6.THE SUPERSACKS SHALL BE WATERPROOF, CUBE SHAPED, POLYPROPYLENE WOVEN

FABRIC WITH A FLAT BOTTOM, FOUR LIFTING LOOPS, RATED FOR A MINIMUM OF 2.5

TONS WORKING LOAD WITH A 5:1 SAFETY FACTOR.

7.THE POLY SHEETING SHALL BE A MINIMUM OF 6 MIL THICKNESS. THE ROLL SHALL BE A

MINIMUM OF 12 FEET WIDE AND LONG ENOUGH TO SPAN THE LENGTH OF THE

COFFERDAM WITHOUT A SEAM.

8. THE CONTRACTOR SHALL PROVIDE DEWATERING, AS NEEDED, ON THE BACK SIDE OF

THE COFFERDAM IN THE WORK AREA. DEWATERING OPERATIONS SHALL CONSIST OF A

PRIMARY PUMP AND BACKUP PUMP BOTH LARGE ENOUGH TO MAINTAIN THE WATER

LEVEL SO THE EXCAVATION AND BACKFILL OPERATIONS CAN BE COMPLETED.

DEWATERING OPERATIONS SHALL BE MONITORED 24 HOURS A DAY UNTIL THE PUMPS

CAN BE SAFELY SHUT DOWN WITHOUT THE RISK OF DAMAGE TO THE WORK.

9.WHEN THE WORK IS COMPLETED ALL SUPERSACKS, SANDBAGS, POLY SHEETING AND

ALL DEBRIS SHALL BE CLEANED UP AND LEGALLY DISPOSED OF OFFSITE.

PART FINE MATERIAL MEETING THE GRADATION IN TABLE 1 AND 2 THIS SHEET. CULVERT

STREAMBED MATERIALS SHALL BE MIXED ON SITE BEFORE PLACEMENT. ADD FINES (NO
