NOTES:

1. OFFSETS AND ELEVATIONS AT SELECTED ALIGNMENT STATIONS ARE PRESENTED IN THE TABLE FOR EACH LETTER ID SHOWN.

2. STATIONS SELECTED INDICATE CHANGES IN WIDTH OF THE MIDDLE BENCH OR OTHER SIGNIFICANT VARIATIONS IN THE SECTION GEOMETRY ACCORDING TO THE DRAWINGS. TRANSITIONS

BETWEEN STATIONS INDICATING CHANGES IN WIDTH AT MIDDLE BENCH ARE LINEAR.

3. FINISH GRADING TEMPLATE SHOWS FINAL GRADE AND DOES NOT INCLUDE ADDITIONAL EXCAVATION REQUIRED TO INSTALL ROCK STRUCTURES.

4. ALL OFFSETS ARE MEASURED PERPENDICULAR TO THE SITE 2-3 ALIGNMENT.

5. OFFSETS PRESENTED FOR "F" ARE APPROXIMATE AND FOR REFERENCE ONLY. A CONSTANT GRADE BETWEEN POSITION/ELEVATION OF "E" AND THE ELEVATION SHOWN AT "F" SHOULD BE

FOLLOWED TO DAYLIGHT AT EXISTING GRADE.

7. ORDINARY HIGH WATER IS A REGULATORY ELEVATION DEFINED AT THE SITE. LIMITATIONS ON WHEN WORK MAY BE PERFORMED BELOW THE ORDINARY HIGH WATER ARE DEFINED IN

SPECIFICATION SECTION 01 57 19. ORDINARY HIGH WATER AT SITE 2-3 IS DEFINED BY WORK AREA AS FOLLOWS:

SHEET NOTES:

1. THE LONGITUDINAL LAUNCHABLE ROCK TOE PROTECTION IS KEYED INTO THE EXISTING CHANNEL BED AND WILL

REQUIRE EXCAVATION OF CHANNEL BED MATERIAL FOR PLACEMENT.

2. EXCAVATION OF THE CHANNEL BED AND PLACEMENT OF THE LONGITUDINAL LAUNCHABLE ROCK TOE PROTECTION

WILL REQUIRE INSTALLATION OF TURBIDITY CURTAINS PRIOR TO WORK. REFER TO SPECIFICATION SECTION 01 57 19.

3. EXCAVATED CHANNEL MATERIAL CAN BE USED TO FILL UNDER THE PLANTING BENCH OR AS FILL MATERIAL BEHIND

THE ROCK BANK PROTECTION.

4. SEED ALL TOPSOIL PER EROSION CONTROL SHEETS AND SPECIFICATIONS.

5. INSTALL EROSION CONTROL FABRIC OVER TOPSOIL ON SOIL-FILLED ROCK SLOPE PROTECTION PER DETAIL 26, SHEET C-507.

6. BEDDING MATERIAL LAYER SHALL CONSIST OF MINIMUM 6" THICK FINE BEDDING LAYER PLACED ON SUBGRADE THEN

MINIMUM 6" THICK COARSE BEDDING LAYER PLACED ON TOP OF FINE BEDDING LAYER.

7. EXCAVATED MATERIAL FROM INSTREAM EXCAVATION TO PLACE ROCK CAN BE SIDECAST AND PLACED BELOW OR

MIXED INTO THE BLENDED BEDDING MATERIAL.

8. BLENDED BEDDING MATERIAL COMPOSED OF 50/50 MIXTURE OF FINE AND COARSE BEDDING LAYER MATERIAL.

9. LETTERS SHOWN IN CALLOUTS ON THIS SHEET REFERENCE THE OFFSET/ELEVATION DATA TABLE.

SHEET NOTES:

1. THE LONGITUDINAL LAUNCHABLE ROCK TOE PROTECTION IS KEYED INTO THE EXISTING CHANNEL BED AND WILL

REQUIRE EXCAVATION OF CHANNEL BED MATERIAL FOR PLACEMENT.

2. EXCAVATION OF THE CHANNEL BED AND PLACEMENT OF THE LONGITUDINAL LAUNCHABLE ROCK TOE PROTECTION

WILL REQUIRE INSTALLATION OF TURBIDITY CURTAINS PRIOR TO WORK. REFER TO SPECIFICATION SECTION 01 57 19.

3. EXCAVATED CHANNEL MATERIAL CAN BE USED TO FILL UNDER THE PLANTING BENCH OR AS FILL MATERIAL BEHIND

THE ROCK BANK PROTECTION.

4. SEED ALL TOPSOIL PER EROSION CONTROL SHEETS AND SPECIFICATIONS.

5. INSTALL EROSION CONTROL FABRIC OVER TOPSOIL ON SOIL-FILLED ROCK SLOPE PROTECTION PER DETAIL 26, SHEET C-507.

6. BEDDING MATERIAL LAYER SHALL CONSIST OF MINIMUM 6" THICK FINE BEDDING LAYER PLACED ON SUBGRADE THEN

MINIMUM 6" THICK COARSE BEDDING LAYER PLACED ON TOP OF FINE BEDDING LAYER.

7. LETTERS SHOWN IN CALLOUTS ON THIS SHEET REFERENCE THE OFFSET/ELEVATION DATA TABLE.

8. EXCAVATED MATERIAL FROM INSTREAM EXCAVATION TO PLACE ROCK CAN BE SIDECAST AND PLACED BELOW OR

MIXED INTO THE BLENDED BEDDING MATERIAL.
