DESCRIPTION:
THE WORK SHOULD CONSIST OF INSTALLING A TEMPORARY PUMP AROUND AND SUPPORTING MEASURES TO DIVERT FLOW AROUND THE WORK AREA AND DEWATER WORK AREA.
1. THE CONTRACTOR SHOULD STAY WITHIN THE LIMITS OF THE DISTURBANCE AS SHOWN ON THE PLANS AND MINIMIZE DISTURBANCE WITHIN THE WORK AREA WHENEVER POSSIBLE.
2. THE CONTRACTOR SHOULD ONLY BEGIN WORK IN AN AREA WHICH CAN BE COMPLETED BY THE END OF THE DAY. AT THE END OF EACH WORK DAY, THE WORK AREA MUST BE STABILIZED AND THE
PUMP AROUND REMOVED.
3. SANDBAG DIKES SHOULD BE SITUATED AT THE ENDS OF THE WORK AREA AS SHOWN ON THE PLANS, AND CLEAN STREAM FLOW SHOULD BE PUMPED AROUND THE WORK AREA. THE PUMP SHOULD
DISCHARGE ONTO A STABLE VELOCITY DISSIPATER MADE OF RIPRAP OR SANDBAGS. THE VELOCITY DISSIPATER SHALL BE LOCATED ON THE STREAM BANK, NOT TO ENCROACH ON OR BELOW THE
STREAM'S ORDINARY HIGH-WATER LINE.
4. WATER FROM THE WORK AREA SHOULD BE PUMPED TO A SEDIMENT FILTERING MEASURE SUCH AS A DEWATERING BASIN, SEDIMENT BAG, OR OTHER APPROVED SOURCE. THE MEASURE SHOULD BE
LOCATED SUCH THAT THE WATER DRAINS DOWNSTREAM OF THE WORK AREA.
5. FOR STREAMWORK REPAIR PROJECTS LONGER THAN 400 LINEAR FEET, MULTIPLE WORK AREAS SHALL BE ESTABLISHED IN SUCCESION. ONCE AN AREA IS COMPLETED AND STABILIZED, THE CLEAN
WATER DIKE SHOULD BE REMOVED. AFTER THE FIRST SEDIMENT FLUSH, A NEW CLEAN WATER DIKE WOULD BE ESTABLISHED FROM THE OLD SEDIMENT DIKE. FINALLY, UPON ESTABLISHMENT OF A
NEW SEDIMENT DIKE BELOW THE OLD ONE, THE OLD SEDIMENT DIKE SHOULD BE REMOVED.
6. A PUMP AROUND MUST BE INSTALLED ON ANY TRIBUTARY OR STORM DRAIN OUTFALL WHICH CONTRIBUTES BASEFLOW TO THE WORK AREA. THIS SHOULD BE ACCOMPLISHED BY LOCATING A
SANDBAG DIKE AT THE DOWNSTREAM END OF THE TRIBUTARY OR STORM DRAIN OUTFALL AND PUMPING THE STREAM FLOW AROUND THE WORK AREA. THIS WATER SHOULD DISCHARGE ONTO THE
SAME VELOCITY DISSIPATER USED FOR THE MAIN STEM PUMP AROUND.
STREAM CROSSING CONSTRUCTION SEQUENCE
Q
1. INSTALL ALL EROSION CONTROL MEASURES ADJACENT TO PLANNED CROSSING PRIOR TO DISTURBANCE. MINIMIZE DISTURBANCE TO THE EXTENT PRACTICAL.
2. PLACE DAM AROUND AREA TO BE EXCAVATED SIMILAR TO DETAIL 1 USING CLASS A RIP-RAP INSIDE COFFER DAM, POLYETHYLENE FABRIC AND SANDBAGS OR ADDITIONAL CLASS 1 RIP-RAP
o (OUTSIDE COFFER DAM).
3. PLACE POLYETHYLENE FABRIC ON OPPOSITE STREAMBANK IF NEEDED TO PREVENT EROSION.
4. INSTALL DEWATERING PUMP AND DEWATER AREA INSIDE DAM. PUMP HOSE TO DISCHARGE TO SETTLING BASIN OR SILT BAG(S) PRIOR TO ENTERING CREEK. PLACE SETTLING BASIN OR SILT BAG(S)
ABOVE 2 YEAR FLOOD ELEVATION WHEREVER PRACTICAL. ENGINEER TO APPROVE TYPE OF SILT BAG PRIOR TO INSTALLATION.
5. CLEAR AND EXCAVATE STREAM AND BANKS AS NECESSARY TO INSTALL PIPELINE. CONTRACTOR SHALL CONTINUOUSLY MAINTAIN EROSION CONTROL MEASURES AND MAKE EVERY EFFORT TO
MINIMIZE DISTURBANCE.
W
cn w 6. INSTALL PIPELINE WITHIN DEWATERED AREA AND BACKFILL TO ORIGINAL CREEK BOTTOM ELEVATION.
z 7. REMOVE DAM AND STABILIZE ALL DISTURBED AREAS ON BANKS OF CREEK. ENSURE NEW BANKS AND EARTH ARE FULLY COMPACTED AND STABILIZED.
m 8. BANKS TO BE RESTORED WITHIN 48 HOURS IN ACCORDANCE WITH CONTRACT DRAWINGS. SEE DETAIL 2/CD4. PERMANENTLY SEED ALL OTHER DISTURBED AREAS.
9. ONCE AREA HAS BEEN STABILIZED, OBTAIN APPROVAL FROM ENGINEER TO REMOVE ALL TEMPORARY EROSION CONTROL MEASURES AND RETURN THOSE LOCATIONS TO ORIGINAL CONDITION AS
CLOSELY AS PRACTICAL.
