NOTES:

1. NEW PIPE SHALL BE 12" OR 24" PROFILE WALL HDPE AS SPECIFIED.

2. CUT AND REPAIR EXISTING PIPE ENDS THAT ARE DAMAGED, CORRODED OR BENT

3. ALL PIPE SYSTEMS SHALL BE INSTALLED IN ACCORDANCE WITH ASTM D2321, "STANDARD PRACTICE FOR

UNDERGROUND INSTALLATION OF THERMOPLASTIC PIPE FOR SEWERS AND OTHER GRAVITY FLOW

APPLICATIONS", LATEST ADDITION

4. MEASURES SHOULD BE TAKEN TO PREVENT MIGRATION OF NATIVE FINES INTO BACKFILL MATERIAL, WHEN REQUIRED.

5. FOUNDATION: WHERE THE TRENCH BOTTOM IS UNSTABLE, THE CONTRACTOR SHALL EXCAVATE TO A DEPTH REQUIRED BY THE CONTRACTORS ON SITE TESTING REPRESENTATIVE AND REPLACE WITH SUITABLE MATERIAL. AS AN ALTERNATIVE AND AT THE DISCRETION OF THE CONTRACTORS ON SITE TESTING REPRESENTATIVE, THE TRENCH BOTTOM MAY BE STABILIZED USING A GEOTEXTILE MATERIAL.

6. MINIMUM COVER: MINIMUM COVER, H, IN NON-TRAFFIC APPLICATIONS (GRASS MATERIAL OR LANDSCAPE AREAS) IS 24" FROM THE TOP OF PIPE TO GROUND SURFACE ADDITIONAL COVER MAY BE REQUIRED

DURING CONSTRUCTION TO ACCOMMODATE CONSTRUCTION EQUIPMENT LOADING.

GEOTEXTILE

NOTES:

1. ENSURE THAT THE SUBGRADE FOR THE FILTER AND RIPRAP FOLLOWS THE REQUIRED

LINES AND GRADES SHOWN IN THE PLAN. COMPACT ANY FILL REQUIRED IN THE

SUBGRADE TO THE DENSITY OF THE SURROUNDING UNDISTURBED MATERIAL. LOW

AREAS IN THE SUBGRADE ON UNDISTURBED SOIL MAY ALSO BE FILLED BY INCREASING

THE RIPRAP THICKNESS.THE RIPRAP AND GRAVEL FILTER MUST CONFORM TO THE

SPECIFIED GRADING LIMITS SHOWN ON THE PLANS.

2. FILTER CLOTH, WHEN USED, MUST MEET DESIGN REQUIREMENTS AND BE PROPERLY

PROTECTED FROM PUNCHING OR TEARING DURING INSTALLATION. REPAIR ANY DAMAGE

BY REMOVING THE RIPRAP AND PLACING ANOTHER PIECE OF FILTER CLOTH OVER THE

DAMAGED AREA. ALL CONNECTING JOINTS SHOULD OVERLAP SO THE TOP LAYER IS

ABOVE THE DOWNSTREAM LAYER A MINIMUM OF 1 FOOT. IF THE DAMAGE IS EXTENSIVE,

REPLACE THE ENTIRE FILTER CLOTH.

3. RIPRAP MAY BE PLACED BY EQUIPMENT, BUT TAKE CARE TO AVOID DAMAGING THE

FILTER.

4. THE RIPRAP MAY BE FIELD STONE OR ROUGH QUARRY STONE. IT SHOULD BE HARD,

ANGULAR, HIGHLY WEATHER-RESISTANT AND WELL GRADED.

5. CONSTRUCT THE APRON ON ZERO GRADE WITH NO OVERFILL AT THE END. MAKE THE

TOP OF THE RIPRAP AT THE DOWNSTREAM END LEVEL WITH THE RECEIVING AREA OR

SLIGHTLY BELOW IT.

6. ENSURE THAT THE APRON IS PROPERLY ALIGNED WITH THE RECEIVING STREAM AND

PREFERABLY STRAIGHT THROUGHOUT ITS LENGTH. IF A CURVE IS NEEDED TO FIT SITE

CONDITIONS, PLACE IT IN THE UPPER SECTION OF THE APRON.

7. IMMEDIATELY AFTER CONSTRUCTION, STABILIZE ALL DISTURBED AREAS WITH

VEGETATION.

OR HIS/HER DESIGNATED REPRESENTATIVESOIL EROSION AND SEDIMENT CONTROL MEASURES

1. ALL EROSION AND SEDIMENTATION CONTROL MEASURES NOTED SHALL BE INSTALLED PRIOR TO START OF CONSTRUCTION AND

SHALL REMAIN IN EFFECT AND BE MAINTAINED THROUGHOUT THE PERIOD OF CONSTRUCTION.

2. SEDIMENTATION FROM WORK ON THIS SITE SHALL BE CONTAINED ON THE SITE AND SHALL NOT BE ALLOWED TO COLLECT ON ANY

OFFSITE AREA OR IN WATERWAYS.

3. CONTRACTOR SHALL APPLY TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES AS SHOWN ON THESE PLANS OR AS DIRECTED BY THE CONTRACTING OFFICER OR HIS/HER DESIGNATED REPRESENTATIVE. CONTRACTOR SHALL REMOVE TEMPORARY MEASURES AS SOON AS PERMANENT STABILIZATION OF SLOPES, DITCHES, AND OTHER EARTH CHANGES HAVE BEEN ACCOMPLISHED.

4. DAILY INSPECTION SHALL BE MADE BY THE CONTRACTOR TO DETERMINE THE EFFECTIVENESS OF EROSION CONTROL MEASURES, AND

ANY NECESSARY REPAIRS SHALL BE MADE WITHOUT DELAY.

5. PERMANENT SOIL EROSION CONTROL MEASURES FOR ANY DISTURBED LAND AREA SHALL BE STABLIZIED AS SOON AS POSSIBLE. WHEN IT IS NOT POSSIBLE TO PERMANENTLY STABILIZE A DISTURBED AREA IMMEDIATELY AFTER COMPLETION OF GRADING WORK, TEMPORARY SOIL EROSION CONTROL MEASURES SHALL BE IMPLEMENTED IMMEDIATELY. ALL TEMPORARY SOIL EROSION CONTROL MEASURES SHALL

BE MAINTAINED UNTIL PERMANENT SOIL EROSION CONTROL MEASURES ARE IMPLEMENTED.

6. CONTRACTOR SHALL PROVIDE PERMANENT GROUND COVER FOR ALL DISTURBED AREAS WITH 3H:1V SLOPES OR FLATTER WITHIN 14 CALENDAR DAYS FOLLOWING THE COMPLETION OF CONSTRUCTION AND ALL DISTURBED AREAS WITH SLOPES STEEPER THAN 3H:1V WITHIN 7 CALENDAR DAYS

AFTER COMPLETION OF CONSTRUCTION.

7. SEE SECTION 32 92 19 IN THE SPECIFICATIONS FOR DETAILS REGARDING MAINTENANCE AND APPLICATION OF SEEDING, SOIL CONDITIONERS, FERTILIZERS, AND MULCH.

TEMPORARY SILT FENCE NOTES:

1. THE CONTRACTOR SHALL COMPLETE ALL TEMPORARY SILT FENCE INSTALLATION PRIOR TO

COMMENCEMENT OF EXCAVATION OF DEBRIS AND SEDIMENT FROM THE CHANNEL.

2. WIRE FABRIC SHALL BE A MINIMUM OF 32" IN WIDTH AND SHALL HAVE A MINIMUM OF 6 LINE WIRES

WITH 12" STAY SPACING.

3. FILTER FABRIC SHALL HAVE A MINIMUM OF 36" WIDTH. FILTER FABRIC SHALL BE FASTENED

ADEQUATELY TO THE FENCE FABRIC AS DIRECTED BY THE CONTRACTING OFFICER.

4. STEEL POSTS SHALL BE 5 FEET (MIN) IN HEIGHT AND SHALL BE OF THE SELF-FASTENER ANGLE

STEEL TYPE.

5. THE CONTRACTOR SHALL INSPECT TEMPORARY SILT FENCE AT LEAST ONCE EVERY 7 DAYS AND AFTER ANY SIGNIFICANT STORM THAT PRODUCES 0.5 INCHES OR MORE RAINFALL AT THE SITE

AND MAKE ANY REQUIRED REPAIRS IMMEDIATELY. REMOVE SEDIMENT DEPOSITS AS NECESSARY

TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE PRESSURE ON

THE FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING CLEANOUT.

6. THE CONTRACTOR SHALL PERFORM ALL WORK IN SUCH A MANNER THAT STATE WATER QUALITY

STANDARDS OUTSIDE OF THE CONSTRUCTION AREA ARE NOT VIOLATED. ALL EROSION AND

SEDIMENT CONTROL MEASURES SHALL BE IN ACCORDANCE WITH THE NORTH CAROLINA EROSION

AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL.
