1. THE TOP SEVERAL FEET OF THE EMBANKMENT CONTAINS SLAG MATERIAL. THIS LIGHTWEIGHT MINING

WASTE MATERIAL DOES NOT CONTAIN LEAD.

2. SAFETY NOTE: NOTE THAT WATER IS NOT CURRENTLY FLOWING THROUGH THE PIPE, BUT HAS

CREATED A VOID IN THE EMBANKMENT WHICH IS NOW THE PRIMARY OUTLET. SIZE OF THE CAVITY IS

UNKNOWN. CARE SHOULD BE TAKEN DURING EXCAVATION TO PREVENT COLLAPSE, AND ALSO TO

COMPACT THE VOID TO THE MAXIMUM EXTENT PRACTICAL.

3. FILL IN VOID CREATED AT BASE OF SLUMP AT BEAVER DAM,TO RE-ESTABLISH SLOPE.

4. REMOVE BEAVER DAM. DO NOT USE MATERIAL FOR SPILLWAY FILL. PLACE DOWNSTREAM OUTSIDE OF

SPILLWAY AREA.

ROAD BED CONSTRUCTION NOTES

6. MAXIMUM COMPACTED DEPTH OF 6 FEET

SHALL BE APPLIED TO THE ROAD FILL AREA.

7. ROADBED FILL AREA SHALL BE COMPACTED

SO THERE IS NO VISUAL DISPLACEMENT.

8. ROADWAY RECONDITIONING ON FR 2741 IS

NOT REQUIRED FOR THIS CONTRACT. ANY

ROADWAY CONDITIONING THAT IS

COMPLETED BY CONTRACTOR WILL BE

CONSIDERED INCIDENTAL.

9. PRIOR TO THE PLACEMENT OF AGGREGATE

COURSES, THE SUBGRADE SHOULD BE LEFT IN

A CONDITION FREE OF RUTS AND

DEPRESSIONS AND THAT WILL PERMIT

DISPERSED DRAINAGE. TEMPORARY

INSTALLATION OF WATER BARS MAY BE

REQUIRED TO MINIMIZE EROSION IF

OPERATIONS WILL STOP FOR MORE THAN 7

DAYS WITHOUT PERMANENT STABILIZATION.

EROSION CONTROL MEASURES ARE

INCIDENTAL TO CLEARING AND GRUBBING

AND ROADWAY EXCAVATION.

10. INSTALL FOUR OUTLET DITCHES AND TWO

DIPS. LOCATION TO BE DETERMINED IN FIELD

AS CONDITIONS DICTATE.MUST OBTAIN

APPROVAL FROM COR.

11. TWO TURNAROUNDS WILL BE

CONSTRUCTED AS SHOWN ON SHEET 03,

UNLESS APPROVED BY THE COR.

12. ALL EFFORTS SHALL BE MADE TO PREVENT

SLAG MATERIAL FROM BEING USED WITHIN

THE TOP 6 INCHES OF THE ROADBED.

13. OPTIONAL BID ITEMS: 2" OF LOOSE, 2"

MINUS CRUSHED AGGREGATE ADDED TO

ROADBED AND TURN-AROUNDS.
