GENERAL NOTES:
1. La IS THE LENGTH OF THE RIP RAP APRON.
2. d = 1.5 TIMES THE MAXIMUM STONE DIAMETER BUT NOT LESS THAN 12°'
3. IN A WELL-DEFINED CHANNEL EXTEND THE APRON UP THE CHANNEL BANKS TO
AN ELEVATION OF 6" ABOVE THE MAXIMUM TAIL -WATER DEPTH OR TO THE TOP
OF 'THE BANK, WHICHEVER IS LESS,
4, A FILTER BLANKET OR FILTER FABRIC SHOULD BE INSTALLED BETWEEN THE
RIP RAP AND SOIL FOUNDATION,
5. COMPACT ANY REQUIRED FILL TO DENSITY OF SURROUNDING UNDISTURBED
MATERIAL,
6. RIP RAP MAY BE FIELDSTONE OR ROUGH QUARRY STONE AND SHALL BE HARD,
ANGULAR AND WELL -GRADED,
7. CONSTRUCT APRON AT ZERO GRADE. TOP OF RIP RAP SHALL BE LEVEL WITH
THE RECEIVING CHANNEL. OR SLIGHTLY LOWER.
8. ALIGN APRON WITH RECEIVING CHANNEL. OR STREAM. ASSURE APRON IS
STRAIGHT THROUGHOUT ITS LENGTH,
9, END WIDTH OF APRON TO BE EQUAL TO WIDTH OF RECEIVING CHANNEL.
