NOTES:

1. GEOTEXTILE IS OFFSET FOR CLARITY. GEOMBRANE IS OFFSET IN ANCHOR TRENCHES FOR CLARITY.

2. REMOVE AND REINSTALL THE EXISTING GUIDERAIL AND POSTS, AS REQUIRED. SEE SPECIFICATIONS.

3. ONCE THE TEMPORARY HAUL ROAD IS EXCAVATED TO GRADE, THE CONTRACTOR MAY ADD SUPPLEMENTAL

AGGREGATES AND GEOTEXTILE AND/OR GEOGRID TO THE EXCAVATION SUBGRADE TO MAKE IT MORE DRIVABLE AND

TO REDUCE ROAD MAINTENANCE DURING CONSTRUCTION. SUCH SUPPLEMENTAL MATERIALS WILL BE AT NO

ADDITIONAL COST TO THE GOVERNMENT. PRIOR TO RESTORING THE EMBANKMENT BACK TO ITS ORIGINAL

GEOMETRY, ANY SUPPLEMENTAL MATERIALS INSTALLED FOR THE TEMPORARY HAUL ROAD MUST BE REMOVED.

4. ONCE THE TEMPORARY HAUL ROAD IS NO LONGER NEEDED TO PERFORM THE CONTRACT WORK, EXISTING BOULDER

AND EARTH FILL TRANSITION MATERIAL AND EXISTING ARMOR STONE ON THE DOWN STREAM FACE SHALL BE

REPLACED IN KIND TO THEIR ORIGINAL CONFIGURATION AS SHOWN.

5. SEE SHEET C-503, DETAIL 2 FOR DETAILS OF TEMPORARY, ONE-INCH MINUS SOIL LEVEL, WHICH NEEDS TO BE IN

PLACE BEFORE PLACING AASHTO #57 STONE OVER THE GEOTEXTILE ON THE UPSTREAM EMBANKMENT SLOPE.

6. A FINER ROCK FILTER MAY EXIST BETWEEN THE EXISTING BOTTOM OF RIPRAP AND THE UNDERLYING SOIL

SUBGRADE. IF A FINER ROCK FILTER DOES EXIST, IT WILL LIKELY BE ABOUT 1' TO 3'-THICK AND WILL OVERLIE THE

EXISTING BOTTOM OF RIPRAP LINE SHOWN. SINCE THE EXISTENCE OF THIS FINER ROCK FILTER IS UNKNOWN, IT IS

NOT SHOWN. EXISTING RIPRAP AND ROCK FILTER MATERIAL (IF IT EXISTS) SHALL BE SEGREGATED DURING

EXCAVATION AND STOCKPILED SEPARATELY. IF THE ROCK FILTER DOES EXIST, DO NOT REINSTALL THE ROCK FILTER

MATERIAL INTO THE PROPOSED LINER SYSTEM; RATHER, DISPOSE OF IT ONSITE.

7. RIPRAP THICKNESS SHALL BE 4.5'-THICK AT CREST (DETAIL 4, THIS SHEET), LINEARLY INCREASE TO 9.7'-THICK AT

MIDSLOPE ABOVE THE SUBGRADE SLOPE BREAK (DETAIL 3, THIS SHEET), AND THEN TAPER TO A CONSTANT 8'

THICKNESS ON THE LOWER 1V:3H SLOPE (DETAIL 2 & 3, THIS SHEET). FOR FULL EMBANKMENT SLOPE VIEW, SEE

SHEET C-301, SECTION 2.

8. ON DETAIL 1, THE EXISTING USGS HORIZONTAL PIPE HAS BEEN PROJECTED ONTO THIS DETAIL TO PROVIDE A

GENERAL IDEA OF WHERE THIS PIPE DAYLIGHTS ON THE UPSTREAM BERM IN THE VICINITY OF THE UPSTREAM BERM

ANCHOR TRENCH. HOWEVER, THE LINER DETAIL SHOWN ON DETAIL 1 DOES NOT REPRESENT THE REQUIRED PIPE

PENETRATION DETAIL AT THIS LOCATION. FOR THE REQUIRED PIPE PENETRATION DETAIL AT THIS LOCATION, REFER

4. ALL EXISTING INSTRUMENTATION & UTILITIES IN AND ON USGS GAUGE SHED WILL BE REMOVED BY OTHERS PRIOR TO SHED DEMO.

5. REMOVE EXISTING HANDRAILS, PLATFORM (A.K.A., WALKWAY), STEPS, AND ANCILLARY FEATURES RELATED TO THE USGS SHED

PRIOR TO COMMENCING USGS SHED DEMOLITION ACTIVITIES. THESE FEATURES SHALL BE REINSTALLED AFTER RIPRAP PLACEMENT

AROUND THE USGS SHED, UNLESS OTHERWISE APPROVED OR DIRECTED. ANY REQUIRED MODIFICATIONS TO EXISTING HANDRAILS, PLATFORM, STEPS, AND ANCILLARY FEATURES SHALL BE PERFORMED AS NECESSARY AND APPROVED TO PROPERLY REINSTALL TO

THE USGS SHED'S NEW PRECAST CONCRETE SLAB AS SHOWN.

6. REMOVE THE EXISTING, USGS SHED DOWN TO THE TOP EDGE OF THE EXISTING, 42-INCH DIAMETER CORRUGATED METAL PIPE (CMP)

AS SHOWN AND SPECIFIED IN SECTION 02 41 00 DEMOLITION. USGS SHED REMOVAL SHALL OCCUR PRIOR TO REMOVAL OF EXISTING

RIPRAP AROUND THE SHED (I.E., RIPRAP WITHIN A 30-FOOT RADIUS OF THE SHED'S CENTER). CAREFULLY REMOVE USGS SHED IN A

WAY THAT DOES NOT DAMAGE THE EXISTING, 42-INCH DIAMETER CMP IN ANY WAY. REMOVAL WORK SHALL ALSO INCLUDE CAREFUL

REMOVAL OF EXISTING METAL PIPE FLANGES & BRACKETS ATTACHED TO THE EXISTING, 42-INCH DIAMETER CMP, AND CAREFUL

REMOVAL OF THE EXISTING, 8-INCH THICK REINFORCED CONCRETE SLAB THAT SUPPORTS THE USGS SHED'S CONCRETE MASONRY

UNIT (CMU) WALLS.

7. EXCAVATE TO STABLE SLOPE TO INSTALL PROTECTIVE STEEL PIPE CASING AND PIPE FOOTING, OR USE APPROVED SHORING FOR

VERTICAL CUT. BACKFILL AND COMPACT EXCAVATED AREA FOR PIPE INSTALL USING 1-INCH MINUS SOIL.

NOTES:

1. GEOTEXTILE IS OFFSET FOR CLARITY. GEOMEMBRANE IS OFFSET FOR CLARITY IN ANCHOR TRENCHES AND ON GEOMEMBRANE

BOOT DETAILS.

2. ANY DAMAGE TO THE FACTORY-APPLIED EPOXY COATING OF THE 54" O.D. PROTECTIVE STEEL PIPE CASING SHALL BE REPAIRED BY

RECOATING WITH EPOXY PAINT AS SPECIFIED AND TO THE APPROVAL OF THE COR.

3. CONTRACTOR SHALL TEMPORARILY CAP/COVER THE EXISTING 42" CMP BEFORE COMMENCING DEMOLITION ACTIVITIES TO ENSURE

THAT NO DEBRIS FALLS DOWN THE PIPE. CAP/COVER SHALL BE RIGID AND OF SUFFICIENT STRENGTH TO WITHSTAND ANY FALLING

DEMOLITION DEBRIS.

8. ANNULAR SPACE SHALL BE GROUTED USING NON-SHRINK GROUT AS SHOWN AND SPECIFIED IN SPEC. SECTION 03 30 53

MISCELLANEOUS CAST-IN-PLACE CONCRETE.

9. ON DETAIL 4, THE VERTICAL EXTENT OF GEOTEXTILE BOOT SHALL EXTEND 6" ABOVE TOP EDGE OF GEOMEMBRANE BOOT.

GEOTEXTILE BOOT ON SLOPE SHALL OVERLAP MAIN GEOTEXTILE BOOT BY A MINIMUM OF 12 INCHES AS SHOWN.

10. ON DETAIL 4, BASE OF THE FIELD-FABRICATED GEOMEMBRANE BOOT FOR ATTACHING TO PROTECTIVE STEEL PIPE CASING SHALL

EXTEND A MINIMUM OF 12-INCHES BEYOND THE PIPE CASING AS SHOWN. CONSIDERING THAT THE PIPE BOOT WILL BE ON A 1V:2H

SLOPE, THE BOOT'S BASE WILL NEED TO HAVE AN ELLIPTICAL OPENING HAVING THE FOLLOWING DIMENSIONS: IN THE NORTH-SOUTH

DIRECTION, THE INSIDE EDGE OF THE ELLIPSE SHALL BE 60.5 TO 61.5 INCHES AND THE OUTSIDE EDGE SHALL BE AT LEAST 84.5

INCHES, UNLESS OTHERWISE APPROVED. IN THE EAST-WEST DIRECTION, THE INSIDE EDGE OF THE ELLIPSE SHALL BE 54.5 TO 55.5

INCHES AND THE OUTSIDE EDGE SHALL BE AT LEAST 78.5 INCHES, UNLESS OTHERWISE APPROVED.

11. ON DETAIL 4, THE LINER CONNECTION DETAIL SHOWN IS ALONG THE SOUTH SIDE OF THE USGS GAUGE STATION. THE CONNECTION

DETAIL ON THE NORTH SIDE OF THE USGS STATION IS THE SAME, EXCEPT THAT THE GEOMEMBRANE BOOT HEIGHT SHALL BE ABOUT

43 INCHES AND THE GEOTEXTILE BOOT HEIGHT SHALL BE ABOUT 49 INCHES. IN BETWEEN THE NORTH AND SOUTH SIDES, THE BOOT

HEIGHTS SHALL VARY BETWEEN THESE NORTH AND SOUTH SIDE BOOT HEIGHTS. THE UPPER EDGE OF THE GEOMEMBRANE AND

GEOTEXTILE BOOTS SHALL BE HORIZONTAL, WHILE THE LOWER EDGE SHALL BE FLUSH WITH THE 1V:2H SLOPE.

12. GEOGRID SPREADER PIPE SHALL BE GALVANIZED STEEL PIPE, 6" DIA. NPS, 3/4" WALL THICKNESS, 14 LF EACH. GEOGRID SPREADER

PIPES SHALL BE INSTALLED AND CONNECTED TO EACH OTHER USING STAINLESS STEEL CABLES OR GALV. THREADED ROD AS

SHOWN ON SHEET C-505, DETAILS 1 & 3 AND SPECIFIED IN SPEC. SECTION 05 12 10 USGS GAUGE SHED MODIFICATIONS. INSTALL

GEOGRID SPREADER PIPES AND CONNECTING CABLES OR THREADED ROD PRIOR TO PLACING ANY AASHTO #57 COARSE AGGREGATE

OVER GEOGRID DOWN-GRADIENT OR UPGRADIENT OF THE USGS GAUGE SHED.

13. EXISTING 4" DIA. HORIZONTAL STEEL PIPES SHALL BE ADEQUATELY SUPPORTED DURING THE CONTRACT WORK TO PREVENT FROM

DAMAGE. PIPE MAY BE TEMPORARILY CUT OFF AND CAPPED TO FACILITATE CONSTRUCTION, BUT MUST BE REINSTALLED BACK TO

ORIGINAL CONDITON. 8" DIA. GALVANIZED STEEL PIPE SLEEVES SHALL BE INSTALLED OVER THE EXISTING HORIZONTAL STEEL PIPES

PRIOR TO BACKFILLING AS SHOWN. USE CENTRALIZERS TO CENTER THE 8" PIPE SLEEVES. CEMENT-BENTONITE GROUT SHALL BE

INJECTED OR TREMIE-GROUTED IN THE PIPE ANNULUS BETWEEN THE 2 PIPES. ANY DAMAGED TO THE EXISTING PIPES SHALL BE

REPAIRED OR REPLACED AS DIRECTED. DAMAGE CAUSED DURING THE CONTRACT WORK SHALL BE REPAIRED OR REPLACED AT NO

ADDITIONAL COST TO THE GOVERNMENT.

14. ON DETAIL 5/SECTION A, THE 3/4" X 8.5" GALV. ANCHOR BOLTS HAVE BEEN PROJECTED ONTO SECTION A TO HIGHLIGHT THE BOLTS, BUT ACTUALLY SHALL BE OFFSET FROM SECTION A BY 2 FEET AS SHOWN ON DETAIL 5/BASE PLATE AND PIPE PLAN. THIS

PROJECTION WAS DONE TO HIGHLIGHT THAT THE 54" O.D. STEEL CASING SHALL BE BOLTED TO THE CONCRETE COLLAR FOOTING.

5. THE 1V:1.5H SLOPE IS SHOWN AS "TEMPORARY" BECAUSE THIS SLOPE WILL ONLY EXIST WHILE THE TEMP HAUL ROAD IS IN USE.

HOWEVER, ONCE THE TEMP HAUL ROAD IS NO LONGER NEEDED FOR CONSTRUCTION, THE TEMPORARY SLOPE SHALL BE FILLED

AGAINST TO RESTORE THE CREST ACCESS ROAD TO ITS ORIGINAL GRADE AS SHOWN.

6. NO AASHTO #57 COARSE AGGREGATE SHALL BE PLACED OVER THE EMBANKMENT SLOPE GEOTEXTILE UNTIL THE ONE-INCH

MINUS SOIL IS PLACED AND COMPACTED OVER THE CONCRETE ANCHOR TRENCH TO THE "TEMP. ONE-INCH MINUS SOIL LEVEL"

1. GEOTEXTILE IS OFFSET FOR CLARITY (I.E., ITS TRUE LOCATION IS DIRECTLY ON THE UNDERLYING LAYER, BUT WAS

OFFSET A SMALL DISTANCE TO DISTINGUISH IT FROM THE UNDERLYING LAYER).

2. GEOMBRANE IS OFFSET IN THE ANCHOR TRENCH FOR CLARITY, BUT IS AT ITS TRUE LOCATION OUTSIDE THE

3. CONCRETE ANCHOR TRENCH SHALL BE BACKFILLED WITH 800 P.S.I (MIN.) FLOWABLE CONCRETE FILL.

4. ONCE THE CONCRETE ANCHOR TRENCH IS CONSTRUCTED AND THE CONCRETE ATTAINS A COMPRESSIVE

STRENGTH OF AT LEAST 600 P.S.I., ONE-INCH MINUS SOIL SHALL BE PLACED AND COMPACTED IN LIFTS AS

SPECIFIED AND TO THE GEOMETRY SHOWN ON TOP OF THE CONCRETE ANCHOR TRENCH.
