TABLE 2. RSP VOLUMES

GENERAL NOTES ON RSP VOLUMES:

· VOLUMES ARE PROVIDED FOR INFORMATIONAL PURPOSES ONLY; CONTRACTOR IS RESPONSIBLE FOR VERIFYING ALL VOLUMES.

· ESTIMATED VOLUMES REPRESENT CURRENT RSP PLACEMENT ON THE BANKS, WHICH IS TIGHTLY INTERLOCKED WITH MINIMAL VOID SPACE. RSP VOLUME ESTIMATES WERE COMPUTED BY MULTIPLYING THE LENGTH, THICKNESS, AND SLOPE LENGTH (SEE RSP

DIMENSIONS TABLE, THIS SHEET).

· RSP SECTION LENGTH AND SLOPE LENGTH WERE SURVEYED AND SECTION THICKNESS WAS ESTIMATED BY PROBING 1.5 FT BELOW GROUND SURFACE ALONG THE TOP OF BANK BEHIND RSP SECTIONS.

· IT IS NOT KNOWN HOW FAR RSP SECTIONS EXTEND BELOW THE CHANNEL BED OR BANK. EXPLORATORY EXCAVATION SHALL BE CONDUCTED AT THE TOES OF ALL RSP SEGMENTS TO IDENTIFY POSSIBLE PRESENCE OF BURIED RSP. ALL SUBSURFACE ROCK SHALL BE

REMOVED AS PART OF THIS WORK, UNLESS THE TOP OF THE SUBSURFACE ROCK IS BELOW THE ELEVATIONS SPECIFIED IN THESE DRAWINGS. HISTORICAL PHOTOS DO NOT SHOW TRENCHING THAT WOULD INDICATE SUBSURFACE ROCK OR THAT RSP WAS CONSTRUCTED

WITH MORE LAYERS ON THE BANK THAN CURRENTLY VISIBLE .

TABLE 1. RSP DIMENSIONS

NOTES ON ASPHALT AND BASE ROCK VOLUME ESTIMATES:

· AREA 2: VOLUME OF ASPHALT AND BASE ROCK WAS ESTIMATED BASED ON STRATIGRAPHY

OBSERVED IN PITS THAT WERE DUG ADJACENT TO THE TRAIL. EXTENT OF BASE ROCK MAY BE WIDER

THAN ASPHALT. ACTUAL DIMENSIONS ALONG THE LENGTH OF THE TRAIL MAY VARY.

TABLE 3. ASPHALT AND TRAIL BASE ROCK VOLUMES

NOTE: NA = NOT APPLICABLE

NOTES ON METHODS FOR RSP VOLUME ESTIMATES (SEE ALSO: RSP DIMENSIONS TABLE, THIS SHEET):

· RSP L1 (SECTION TO BE REMOVED): LAYER 1 ROCK WAS DIVIDED INTO TWO SECTIONS: 1) A DOWNSTREAM ~65 FT LONG SECTION OF EMBEDDED ~1 FT DIA ROCK AND 2) AN UPSTREAM ~45 FT LONG SECTION ~2 FT DIA ROCK. A SECOND LAYER WAS

OBSERVED BY PROBING. THE TOE OF THE UPSTREAM SECTION (TO BE REMOVED) WAS EXPOSED; THEREFORE, NONE OF THE RSP IN L1 IS ASSUMED TO BE EMBEDDED BELOW THE CHANNEL BED.

· RSP R1 (SECTION TO BE REMOVED): LAYER 1 ROCK IS A SINGLE ~70 FT LONG SECTION CONSISTING OF WELL-EMBEDDED ~2 FT DIA ROCK. THE TOE OF THE RSP WAS COVERED IN A GRAVEL BAR DURING OBSERVATION, WHICH WAS NOT EXCAVATED OR

EXPLORED TO COFIRM DEPTH OF RSP. TWO LOCATIONS WERE PROBED BEHIND LAYER 1 AND NO SECOND LAYER WAS OBSERVED.

· R2 (SECTION TO BE REMOVED): LAYER 1 ROCK IS A SINGLE ~70 FT LONG SECTION CONSISTING OF ~2 FT DIA ROCK. A SECOND LAYER WAS OBSERVED BY PROBING. THE TOE OF THE R2 SECTION (TO BE REMOVED) WAS EXPOSED; THEREFORE, NONE OF THE

RSP IN R2 IS ASSUMED TO BE EMBEDDED BELOW THE CHANNEL.

· RSP R2B: LAYER 1 ROCK IS ESTIMATED TO BE A SINGLE ~40 FT LONG SECTION CONSISTING OF A SINGLE LAYER OF ~1.5 FT DIA ROCK, ORIGINATING FROM THE NORTH END OF BRIDGE 1.5 AND EXTENDING INTO THE UPSTREAM CHANNEL BANK.

· RSP L2: LAYER 1 ROCK WAS DIVIDED INTO FOUR SECTIONS: 1) AN UPSTREAM ~40 FT LONG SECTION OF WELL-EMBEDDED ~1 FT DIA ROCK, 2) A ~55 FT LONG SECTION OF ~2 FT DIA ROCK, INCLUDING A ~10 FT LENGTH OF LAUNCHED BOULDERS, 3) A FAILED

~15 FT LONG SECTION OF ~1 FT DIA (REMAINING) ROCK THAT LAUNCHED BOULDERS INTO THE CHANNEL, AND 4) A DOWNSTREAM ~20 FT LONG SECTION OF EMBEDDED ~2 FT DIA ROCK. A SECOND LAYER WAS OBSERVED BY PROBING.

· RSP R3 (SECTION TO BE REMOVED): LAYER 1 ROCK WAS DIVIDED INTO THREE SECTIONS: 1) AN UPSTREAM ~70 FT LONG SECTION OF ~2 FT DIA ROCK, WITH A ~10 FT LONG FAILURE, 2) A ~40 FT LONG SECTION OF ~1.5 FT DIA ROCK, WITH LAUNCHED ROCK

ALONG THE TOE OF THE BANK 3) ~70 FT LONG SECTION OF ~2 FT DIA ROCK, WITH BOULDERS LAUNCHED IN THE CHANNEL. A SECOND LAYER WAS OBSERVED BY PROBING.

· RSP R6: LAYER 1 ROCK WAS DIVIDED INTO THREE SECTIONS: 1) AN UPSTREAM ~60 FT LONG SECTION OF WELL-EMBEDDED ~2 FT DIA ROCK, 2) A FAILED 20 FT LONG SECTION AND 3) A DOWNSTREAM ~50 FT LONG SECTION OF LOOSE ~2.5 FT DIA ROCK.

LAYER 2 VOLUME ASSUMES A SOLID 0.5 FT LAYER BEHIND THE DOWNSTREAM 75 FT OF LAYER 1. LAYER 2 ASSUMPTION IS BASED ON OBSERVATIONS OF 0.5 FT ROCK EMBEDDED IN THE BANK AT FAILURE LOCATIONS, THOUGH A SOLID LAYER WAS NOT OBSERVED AND 0.5 FT ROCK COULD BE CHINK MATERIAL, NOT A SECOND LAYER. PROBING 6 LOCATIONS (TO 1.5' DEPTH) BEHIND THE ROCK WAS NON-CONCLUSIVE. SUBSURFACE ROCK ESTIMATE ASSUMES SUBSURFACE ROCK ALONG THE DOWNSTREAM

~50 FT SECTION OF RSP ONLY (WHERE EMBEDDED ROCK WAS OBSERVED IN CHANNEL BED).

TABLE 6. ESTIMATED SOIL VOLUMES FOR BANK GRADING AFTER RSP REMOVAL

TABLE 4. ESTIMATED RSP BURIAL, RE-USE AND STOCKPILING VOLUMES

1. SOIL VOLUMES WERE ESTIMATED BY DIFFERENCING THE EXISTING AND DESIGN SURFACES UTILIZING AUTOCAD CIVIL3D, THEN SUBTRACTING THE ROCK VOLUME ESTIMATE TO REMOVE THE PORTION OF THE EXISTING SURFACE THAT IS ROCK. DUE TO THE UNKNOWN

ROCK EXTENT INTO THE BANK, ACTUAL SOIL VOLUMES MAY VARY.

NOTE:

1. RSP BURIAL DESIGNS SHOW THE DEPTH OF EXCAVATION TRENCHES IS 4.5 FEET; HOWEVER, THE

CONTRACTOR MAY EXCAVATE DEEPER TO BURY MORE RSP IN A SMALLER AREA AS LONG AS BANKS REMAIN STABLE DURING TRENCHING. TOP ELEVATIONS OF BURIED ROCK SHALL NOT EXCEED THOSE

SHOWN ON DRAWINGS. FINAL BED ELEVATIONS SHALL NOT BE EXCEEDED WITHIN SPECIFIED

TOLERANCES.

2. ALL RSP PLACED IN BURIAL ZONES SHALL BE COVERED WITH NATIVE BED MATERIAL.

3. NO RSP SHALL BE PLACED AT AN ELEVATION HIGHER THAN SHOWN IN DRAWINGS, BUT IT MAY BE

PLACED DEEPER.

4. BEFORE BED EXCAVATION, SCRAPE TOP 0.3 FT OFF BED SURFACE, STOCKPILE SEPARATELY FROM
