GENERAL NOTES:

1. THE EXISTING DRAINAGE SYSTEM CONSISTS OF THE DRAIN INLET(S) AND CONNECTING PIPE(S) AT EACH NOTED STATION. NO MORE THAN TWO DRAINAGE SYSTEMS, NOT ADJACENT, CAN BE REPLACED AT ONE TIME.

EXCAVATED TRENCH WIDTH SHALL BE LIMITED TO THAT INDICATED OR NECESSARY FOR INSTALLATION OF NEW WORK. CONTRACTOR SHALL COMPLETE BACKFILL OPERATION PRIOR TO TRANSITIONING TO THE NEXT

EXISTING DRAINAGE SYSTEM.

2. PIPE SHALL BE PLACED IN THE MAXIMUM LENGTHS AVAILABLE TO ENSURE AS FEW JOINTS AS POSSIBLE.

3. CONTRACTOR SHALL REMOVE ALL DEMOLITION MATERIALS FROM THE SITE AND DISPOSE IN ACCORDANCE

WITH ALL APPLICABLE FEDERAL, STATE, AND LOCAL LAWS AND REGULATIONS.

4. SILT FENCES SHALL BE CONSTRUCTED BY THE CONTRACTOR IN ACCORDANCE WITH THE SPECIFICATIONS TO PROVIDE PROTECTION AT ANY STOCKPILE LOCATIONS OR AREAS OF CONSTRUCTION DISTURBANCES.

SEE SPECIFICATIONS SECTION 01 57 23.00 09 STORM WATER POLLUTION PREVENTION PLAN.

5. FOR STORM WATER POLLUTION PLAN TYPICAL DETAILS, SEE SHEET C-502.

6. PIPE LENGTH SHOULD BE VERIFIED IN THE FIELD. THE NEW CONCRETE PIPE IS INTENDED TO TIE INTO NEWLY

INSTALLED CONCRETE PIPE THAT IS TIED INTO THE HEADWALL.

7. THE SOIL IS HIGHLY ERODIBLE. THE CONTRACTOR SHALL TAKE MEASURES TO CONTROL WATER AS NECESSARY. THE CONTRACTOR SHALL PREVENT CONCENTRATED RUNOFF FROM FLOWING DOWN THE EXCAVATED TRENCH. TEMPORARY BERMS WILL BE REQUIRED ON THE SIDES OF EACH DROP INLET DURING REPLACEMENT. THESE BERMS WILL FORCE THE RAINFALL RUNOFF FROM THE SLOPES TO THE ADJACENT DROP INLET OR FORCE THE WATER TO FLOW UNIFORMLY OVER THE TOP OF THE FRASSED BERMS, BACKFILL SHALL COMMENCE AS SOON AS POSSIBLE. THE SLOPE SHALL BE BROUGHT TO GRADE AND SOD PLACED ON

ALL DISTURBED AREAS.

8. THE CONTRACTOR SHALL CAMERA INSPECT EACH DRAIN LINE AFTER COMPLETION OF CONSTRUCTION ON THAT LINE TO DEMONSTRATE THAT NO CONSTRUCTION DEBRIS, TRASH, OR OTHER SIMILAR TYPE MATERIAL

REMAINS IN THE DRAIN LINE.

2. BACKFILL AROUND THE PIPE SHALL BE SAND WITH A MAXIMUM OF 30% AND

MINIMUM 5% BY DRY WEIGHT PASSING THE NO. 200 SIEVE.

3. ANY ADDITIONAL CLAY REQUIRED ABOVE THE SAND BACKFILL SHALL BE

OBTAINED FROM LOCAL COMMERCIAL SOURCES AND THIS MATERIAL SHALL

BE APPROVED BY THE CONTRACTING OFFICER.

GENERAL NOTES:

1. INSPECT AND REPAIR BMP(S) AFTER EACH STORM EVENT AND REMOVE SEDIMENT WHEN NECESSARY.

2. REMOVED SEDIMENT SHALL BE DEPOSITED TO AN AREA THAT WILL NOT CONTRIBUTE SEDIMENT OFF-SITE AND CAN BE

PERMANENTLY STABILIZED.

3. SILT SCREEN FENCE, AND HAY WATTLES SHALL BE PLACED ALONG SLOPE CONTOURS TO MAXIMIZE PONDING EFFICIENCY.

4. THE ENVIRONMENTAL PROTECTION CONTROLS SHOWN IN THE CONTRACT DRAWINGS MAY NOT FULLY ADDRESS ALL CONCERNS AND PERMIT REQUIREMENTS, BUT ARE PROVIDED TO ESTABLISH A MINIMUM LEVEL OF PROTECTION REQUIRED AT ALL TIMES.

THE CONTRACTOR SHALL CONSIDER HIS WORK OPERATIONS, METHODS, AND CURRENT SITE CONDITIONS TO DEVELOP A COMPLETE PLAN, INCLUDING ADDITIONAL PROTECTION MEASURES AS REQUIRED, TO ASSURE ADEQUATE PERFORMANCE AND COMPLIANCE WITH ALL CONTRACT DOCUMENTS, REGULATIONS, AND PERMITS. REFERENCE SECTION 01 57 20.00 09 ENVIRONMENTAL PROTECTION AND SECTION 01 57 23.00 09 STORM WATER POLLUTION PREVENTION PLAN FOR ADDITIONAL

REQUIREMENTS.

5. ANCHORING WOOD STAKES SHALL BE SIZED, SPACED, DRIVEN, AND BE OF A MATERIAL THAT EFFECTIVELY SECURES THE CHECK. STAKE SPACING SHALL BE A MAXIMUM OF THREE FEET. ALL NON-DEGRADABLE MATERIALS SHALL BE REMOVED WHEN

NO LONGER NEEDED.

6. TRENCHING OF WATTLES MAY BE NECESSARY IF PIPING BECOMES EVIDENT.

7. WATTLES SHOULD NOT BE USED IN HARD BOTTOM CHANNELS.

8. USE OF FLOATING TURBIDITY CURTAINS MAYBE NECESSARY WHEN WORKING AROUND THE WATER'S EDGE.

9. BMP SHALL BE UTILIZED PER THE MDEQ REQUIREMENTS TO PREVENT SEDIMENT RUNOFF. ANY MATERIAL THAT ENTERS THE TOE

DITCH, REGARDLESS OF SOURCE, SHALL BE REMOVED.

10. THE PLACEMENT INTERVAL BETWEEN WATTLE DITCH CHECKS SHALL BE 100' UNLESS SHOWN OTHERWISE ON THE PLANS OR

EROSION CONTROL PLAN APPROVED BY THE CONTRACTING OFFICER.

11. CONTRACTOR SHOULD UTILIZE HAY WATTLES ALONG THE LENGTH OF THE TOE DITCH TO TRAP SEDIMENT FROM PROJECT AREA RUNOFF. HAY WATTLES SHALL BE SPACED SO THAT SUSPENDED SEDIMENT IS REMOVED FROM RUNOFF BEFORE LEAVING THE TOE DITCH

INTO LATERAL DRAINAGE DITCHES.
