GENERAL NOTES:
1.EXISTING TOPOGRAPHIC AND SURVEY INFORMATION SHOWN ON PLANS ARE BASED ON SURVEY PERFORMED BY PIONEER TECHNICAL FOR THE EAST GALLATIN RIVER STREAM AVULSION
RESTORATION IN 2019.
2.CONTRACTOR IS TO MAINTAIN SURVEY STATIONS AND CONTROL LOCATIONS.
3.THE CONTRACTOR SHALL APPLY FOR AND OBTAIN ALL PERMITS NECESSARY FROM APPLICABLE AGENCIES IN ORDER TO PERFORM WORK.
4.IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO LOCATE ALL UTILITIES AND PROTECT THEM FROM DAMAGE. THE LOCATION OF ANY AERIAL OR UNDERGROUND UTILITIES SHOWN ARE
APPROXIMATE AND SOME ITEMS MAY NOT BE INDICATED IN THE PLANS. UNDERGROUND UTILITIES, WHETHER INDICATED OR NOT, SHALL BE LOCATED AND FLAGGED BY THE UTILITIES AT
THE REQUEST OF THE CONTRACTOR. THE CONTRACTOR MUST CALL 811 OR 1-800-424-5555 AT LEAST TWO (2) BUSINESS DAYS PRIOR TO DIGGING. ONLY UPON IDENTIFICATION AND
LOCATION OF ALL UTILITIES SHALL THE CONTRACTOR BEGIN EXCAVATION IN THE AREA, THEN ONLY WITH EXTREME CAUTION TO AVOID ANY POSSIBILITY OF DAMAGE TO THE UTILITY
FACILITY. THE CONTRACTOR SHALL BEAR THE TOTAL EXPENSE OF THE REPAIR OR REPLACEMENT OF SAID UTILITIES DAMAGED BY OPERATION IN CONNECTION WITH PROSECUTION OF THE
WORK. THE CONTRACTOR SHALL COORDINATE CONSTRUCTION EFFORTS WITH CITY OF BOZEMAN AND ALL OTHER LOCAL UTILITY COMPANIES PERTINENT TO PROSECUTION OF WORK.
5.THE CONTRACTOR SHALL HAVE ONE (1) SIGNED COPY OF THE APPROVED PLANS AND A COPY OF ANY PERMITS AND EXTENSION AGREEMENTS NEEDED FOR THE JOB, ON-SITE AT ALL TIMES.
6.THE CONTRACTOR IS RESPONSIBLE FOR THE SAFETY OF ALL PERSONNEL, ALL SITE VISITORS, AND THE GENERAL PUBLIC WHO MAY BE AFFECTED BY THE CONSTRUCTION. THIS INCLUDES BUT
IS NOT LIMITED TO GENERAL AND CHANNEL EXCAVATION, SHORING, TRAFFIC CONTROL, AND SECURITY.
7.IF DURING THE CONSTRUCTION PROCESS, CONDITIONS ARE ENCOUNTERED WHICH COULD INDICATE A SITUATION THAT IS NOT IDENTIFIED IN THE PLANS OR SPECIFICATIONS, THE
CONTRACTOR SHALL CONTACT THE ENGINEER IMMEDIATELY.
8.THE CONTRACTOR IS RESPONSIBLE FOR PROVIDING ALL LABOR AND MATERIALS NECESSARY FOR THE COMPLETION OF THE INTENDED IMPROVEMENTS SHOWN ON THESE DRAWINGS, OR
DESIGNATED TO BE PROVIDED, INSTALLED, OR CONSTRUCTED, UNLESS SPECIFICALLY NOTED OTHERWISE.
9.THE CONTRACTOR SHALL BE RESPONSIBLE FOR RECORDING AS-BUILT INFORMATION ON A SET OF RECORD DRAWINGS KEPT ON THE CONSTRUCTION SITE AND AVAILABLE TO THE ENGINEER
AT ALL TIMES.
10.DIMENSIONS FOR LAYOUT AND CONSTRUCTION ARE NOT TO BE SCALED FROM ANY DRAWING. IF PERTINENT DIMENSIONS ARE NOT SHOWN, CONTACT THE CONSULTANT ENGINEER FOR
CLARIFICATION AND ANNOTATE THE DIMENSION ON THE AS-BUILT RECORD DRAWINGS.
11.THROUGHOUT INSTALLATION OF THE CHANNEL STREAMBED MATERIAL, THE CONTRACTOR SHALL MIX SALVAGED ROCK FROM THE BANK AND TOPSOIL INTO VOIDS OF CHANNEL
STREAMBED MATERIAL. MIXING IS TO BE CONFIRMED ENGINEER IN THE FIELD.
12.RIPRAP AND WILLOW CUTTINGS SHOULD BE INSTALLED AT LOWEST FLOW POSSIBLE WHILE WILLOWS ARE DORMANT DURING FALL AND WINTER SEASON.
13.THE CONTRACTOR SHALL BE RESPONSIBLE FOR SAVING AND PROTECTING ALL EXISTING TREES AND VEGETATION WHERE REMOVAL FOR CONSTRUCTION IS NOT MANDATORY. ALL TREES TO
BE REMOVED OR RELOCATED WILL BE MARKED BY THE CONTRACTOR AND APPROVED BY THE OWNER AND CONSULTANT ENGINEER PRIOR TO REMOVAL.

ON CONSTRUCTION SITES.
15.ALL REMOVED ITEMS SHALL BECOME THE CONTRACTOR'S PROPERTY TO BE DISPOSED OF IN AN APPROVED MANNER IN ACCORDANCE WITH REGULATION BY THE OWNER AT NO
ADDITIONAL EXPENSE TO THE OWNERS, UNLESS SPECIFIED WITHIN THE PLANS. NO CONCRETE, RUBBLE, OR EXTRA MATERIALS SHALL BE BACKFILLED ON SITE.

STREETS AS A RESULT OF CONSTRUCTION.
18.THE CONTRACTOR SHALL RESTORE ALL STAGING AND STOCKPILING AREAS TO THEIR ORIGINAL CONDITION OR BETTER THAN EXISTING UPON COMPLETION OF THE PROJECT. THE COST TO
RESTORE THESE AREAS SHALL NOT BE MEASURED AND PAID FOR SEPARATELY BUT SHALL BE INCLUDED IN THE COST OF THE WORK.
19.THE CONTRACTOR SHALL MAINTAIN ALL HAUL ROUTES AND RESTORE THEM TO THEIR ORIGINAL CONDITION OR BETTER THAN EXISTING UPON COMPLETION OF USE AT NO EXPENSE TO THE
OWNER.

FOOT.
2.FABRIC ENCAPSULATED SOIL (FES) TO USE NORTH AMERICAN GREEN C700BN OR APPROVED EQUAL. WHEN
NECESSARY OVERLAP FABRIC FROM UPSTREAM TO DOWN STREAM. STAKE FABRIC PER SHEET MANUFACTURER'S
RECOMMENDATIONS.

GENERAL NOTES FOR CONSTRUCTING FABRIC ENCAPSULATED SOIL LIFTS:
1. BANKS MAY BE CONSTRUCTED IN EITHER AN UPSTREAM OR DOWNSTREAM DIRECTION, AS LONG AS THE FABRIC IS OVERLAPPED IN THE PROPER DIRECTION.
2. PLACE A SERIES OF THREE OR MORE FORMS ON THE SUBGRADE SO THAT THE FORMS FOLLOW THE PROPOSED STREAM BANK ALIGNMENT (FIGURE A). BUTT THE ENDS OF THE FORMS
TIGHTLY TOGETHER.
3. UNROLL THE OUTER WOVEN COIR FABRIC, PARALLEL TO THE CHANNEL AND POSITION IT SO THAT AT LEAST 3 FT. EXTENDS FOR EMBEDMENT ON THE BANK SIDE OF THE FORMS (FIG B).
DRAPE THE REMAINDER OF THE FABRIC OVER THE TOP OF THE FORMS ON THE STREAM SIDE (FIG B).
4. UNROLL THE INNER NON-WOVEN COIR FABRIC, OVER THE TOP OF THE OUTER FABRIC AND POSITION IT SO THAT AT LEAST 1 FT. OF THE INNER FABRIC EXTENDS AS AN EMBEDMENT
LENGTH ON THE BANK SIDE OF THE FORMS (FIG C). DRAPE THE REMAINDER OF THE FABRIC OVER THE TOP OF THE FORMS ON THE STREAM SIDE AND ALIGN THE LONG EDGES OF THE
INNER AND OUTER FABRICS. STRETCH AND PULL THE FABRIC LAYERS TO REMOVE WRINKLES.
5. PLACE TOPSOIL OVER THE FABRIC ON THE BANK SIDE OF THE FORMS THEN COMPACT. MOISTEN FABRIC AND SPRINKLE SEED ON FABRIC IN AREA INDICATED IN FIGURE D. LEVEL THE
TOPSOIL AND COMPACT (FIG E).
6. FOLD THE LOOSE ENDS OF THE TWO FABRIC LAYERS BACK OVER THE COMPACTED TOPSOIL MATERIAL AND STRETCH TIGHTLY TO REMOVE WRINKLES (FIG F). SECURE WITH WOODEN
STAKES AT A SPACING OF 3 FT OR AS DEFINED BY MANUFACTURER.
****NOTE THAT THE TWO LAYERS OF GEOTEXTILE FABRICS SHOWN CAN BE REPLACED WITH A SINGLE GEOTEXTILE THAT COMBINES WOVEN AND NON-WOMEN PRODUCTS. CONTRACTOR
SHALL GET APPROVAL OF ENGINEER PRIOR TO USE.

3. SECURE THE BANK SIDE EDGE OF THE OUTER FABRIC (WOVEN), WITH A WOODEN STAKE THROUGH THE FABRIC ON 3 FT. CENTERS (SEE PLAN VIEWS). NOTE: THE HOLES FOR STAKES
SHALL NOT BE PRECUT. ALLOW THE STAKE TO BREAK THE MINIMUM NUMBER OF STRANDS AS IT IS BEING DRIVEN. DRIVE STAKES SO THAT A MAXIMUM OF 2 IN. IS LEFT EXPOSED.
