1. DESIGN SHALL SHOW ON THE DRAWINGS THE LOCATIONS WHEREOVERFLOW STRUCTURES SHALL BE INSTALLED. OVERFLOW STRUCTURESARE REQUIRED AT ALL LOW POINTS AND AT A SPACING OF APPROXIMATELY300 FEET WHERE NO LOW POINT IS APPARENT.

2. DESIGNER SHALL SHOW ON THE DRAWINGS THE LOCATIONS WHERE SILTFENCE IS TO BE TURNED UPSLOPE AT THE ENDS. UPSLOPE LENGTHS SHALLBE A MINIMUM OF 10 FEET.

3. POST WHICH SUPPORT THE SILT FENCE SHALL BE INSTALLED ON A SLIGHTANGLE TOWARD THE ANTICIPATED RUNOFF SOURCE. POST MUST BEEMBEDDED A MINIMUM OF ONE FOOT.

4. THE TOE OF THE SILT FENCE SHALL BE TRENCHED IN WITH A SPADE ORMECHANICAL TRENCHER, SO THAT THE DOWNSLOPE FACE OF THE TRENCHIS FLAT AND PERPENDICULAR TO THE LINE OF FLOW.

5. THE TRENCH MUST BE A MINIMUM OF 6 INCHES DEEP AND 6 INCHES WIDETO ALLOW FOR THE SILT FENCE FABRIC TO BE LAID IN THE GROUND ANDBACKFILLED WITH COMPACTED MATERIAL.

6. SILT FENCE SHOULD BE SECURELY FASTENED TO EACH SUPPORT POSTOR TO WIRE BACKING, WHICH IN TURN IS ATTACHED TO THE FENCE POST.THERE SHALL BE A 3 FOOT OVERLAP, SECURELY FASTENED WHERE ENDSOF FABRIC MEET.

7. INSPECTION SHALL BE AS SPECIFIED IN THE SWPPP. REPAIR ORREPLACEMENT SHALL BE MADE PROMPTLY AS NEEDED.

8. SILT FENCE SHALL BE REMOVED WHEN FINAL STABILIZATION IS ACHIEVEDOR ANOTHER EROSION OR SEDIMENT CONTROL DEVICE IS EMPLOYED.

9. ACCUMULATED SILT SHALL BE REMOVED WHEN IT REACHES A DEPTH OFHALF THE HEIGHT OF THE FENCE. THE SILT SHALL BE DISPOSED OF AT ANAPPROVED SITE AND IN SUCH A MANNER AS TO NOT CONTRIBUTE TOADDITIONAL SILTATION.

INTERCEPTOR SWALE GENERAL NOTES:

1. ALL TREES, BRUSH, STUMPS, OBSTUCTIONS AND OTHER MATERIALSHALL BE REMOVED AND DISPOSED OF SO AS NOT TO INTERFEREWITH THE PROPER FUNCTIONING OF THE SWALE.

2. THE SWALE SHALL BE EXCAVATED OR SHAPED TO LINE, GRADEAND CROSS-SECTION AS REQUIRED TO MEET CRITERIA SPECIFIEDHEREIN AND BE FREE OF BANK PROJECTIONS OR OTHERIRREGULARITIES WHICH WILL IMPEDE NORMAL FLOW.

3. ALL EARTH REMOVED AND NOT NEEDED IN CONSTRUCTION SHALLBE DISPOSED OF IN AN APPROVED SPOILS SITE SO THAT IT WILL NOTINTERFERE WITH THE FUNCTIONING OF THE SWALE.

4. DIVERTED RUNOFF FROM A DISTURBED OR EXPOSED UPLAND AREASHALL BE CONVEYED TO A SEDIMENT TRAPPING DEVICE.

5. THE ON-SITE LOCATION MAY NEED TO BE ADJUSTED TO MEETFIELD CONDITIONS IN ORDER TO UTILIZE THE MOST SUITABLE OUTLET.

6. FOR LONGITUDINAL SLOPES LESS THAN 2 PERCENT AND VELOCITIESLESS THAN 6 FEET PER SECOND, THE MINIMUM REQUIRED SWALESTABILIZATION SHALL BE GRASS, EROSION CONTROL MATS ORMULCHING. FOR LONGITUDINAL SLOPES IN EXCESS OF 2 PERCENT ORVELOCITIES EXCEEDING 6 FEET PER SECOND, STABILIZATION ISREQUIRED IN THE FORM OF TURF REINFORCEMENT MATS (ORSTABILIZED RIP-RAP WITH APPROPRIATE SIZE, GRADATION, ANDTHICKNESS AS SPECIFIED IN THE PLANS). SEE NOTES 9 AND 10.

7. MINIMUM COMPACTION FOR THE SWALE SHALL BE 95 PERCENTSTANDARD PROCTOR.

8. INSPECTION SHALL BE AS SPECIFIED IN THE SWPPP.

9. FOR TEMPORARY STABILIZATION RIP-RAP; WIDTH, DEPTH, ANDSURFACE WATER ELEVATION SHOULD BE DESIGNED BY OWNER OROWNER'S REPRESENTATIVE

EROSION CONTROL BLANKETS GENERAL NOTES:

1. NCTCOG STANDARD SPECIFICATIONS (2017) SECTION 202.15.

2. EROSION CONTROL BLANKET SHALL BE INSTALLED VERTICALLY DOWN SLOPE AS SHOWN.

3. PRIOR TO THE INSTALLATION: ALL ROCK, DIRT CLODS, STUMPS, ROOTS, TRASH, AND ANYOTHER OBSTRUCTIONS THAT WOULD PREVENT THE BLANKET FROM LYING IN DIRECTCONTRACT WITH THE SOIL SHALL BE REMOVED.

4. ANCHORING METHODS PROVIDED ARE EXAMPLES OF HE TYPE OF ANCHORING THE ECBMANUFACTURER MAY RECOMMEND. ALWAYS FOLLOW THE MANUFACTURER'SRECOMMENDATIONS FOR ANCHORING BASED ON THE SITE-SPECIFIC APPLICATION.

5. INSTALLATION AND ANCHORING SHALL CONFORM TO THE RECOMMENDATIONS SHOWNWITHIN THE MANUFACTURER'S PUBLISHED LITERATURE FOR THE APPROVED EROSIONCONTROL BLANKET. PARTICULAR ATTENTION MUST BE PAID TO JOINTS AND OVERLAPPINGMATERIAL. AT A MINIMUM, THE END OF EACH ROLL OF ECB SHALL OVERLAP THE NEXT ROLLBY 3 FEET AND THE SIDES OF ROLLS SHALL OVERLAP 4 INCHES.

6. IN ABSENCE OF MANUFACTURE'S LITERATURE, A MINIMUM 11-GAUGE WIRE STAPLES,6-INCHES IN LENGTH AND 1-INCH WIDTH WILL BE USED.

7. AFTER APPROPRIATE INSTALLATION, THE BLANKETS SHOULD BE CHECKED FOR UNIFORMCONTACT WITH THE SOIL, SECURITY OF THE LAP JOINTS, AND THE FLUSHNESS OF THESTAPLES WITH THE GROUND.

8. INSPECTION SHALL BE AS SPECIFIED IN THE SWPPP.
