NOTES:

1) THE DEWATERING & SEDIMENT CONTROL TYPICALS &

MINIMALLY ACCEPTABLE FEATURES TO BE PART OF A

CONTRACTORS' PLAN. REGARDLESS OF ANY PLAN

APPROVED BY THE C.O., MAINTAINING WATER QUALITY

REMAINS THE RESPONSIBILITY OF THE CONTRACTOR

THROUGHOUT THE DURATION OF THE PROJECT.

2) PUMP STREAM WATER AROUND SITE DURING

INSTALLATION OF PRIMARY DEWATERING SYSTEM.

MAINTAIN PUMPING SYSTEM AS A CONTINGENCY TO FLOW

3) MATERIAL HANDLING BAGS MAY BE SUBSTITUTED FOR

SANDBAGS UPON APPROVAL BY C.O. HOWEVER, MINIMUM

DIMENSIONS STILL APPLY.

4) SHOULD BROWN WATER DISCHARGE LINES BE PLACED

UPSLOPE IN VEGETATION AS STAKED AND APPROVED BY

C.O., SEDIMENT AND TURBIDITY SHALL BE REMOVED
