PERIMETER DIKES, SWALES AND ALL DISTURBED SLOPES

STEEPER OR EQUAL TO 3:1 SHALL BE STABILIZED WITH SOD

OR SEED AND ANCHORED STRAW MULCH, OR OTHER APPROVED

STABILIZATION MEASURES, AS SOON AS POSSIBLE BUT NO LATER

THAN SEVEN (7) CALENDAR DAYS AFTER ESTABLISHMENT. ALL AREAS

DISTURBED OUTSIDE OF THE PERIMETER SEDIMENT CONTROL

SYSTEM MUST BE MINIMIZED. MAINTENANCE MUST BE PERFORMED

AS NECESSARY TO ENSURE CONTINUED STABILIZATION. (REQUIRE-

MENT FOR STABILIZATION MAY BE REDUCED TO THREE (3) DAYS

FOR SENSITIVE AREAS.)

7.THE CONTRACTOR SHALL APPLY SOD OR SEED AND ANCHORED

STRAW MULCH, OR OTHER APPROVED STABILIZATION MEASURES

TO ALL DISTURBED AREAS AND STOCKPILES WITHIN FOURTEEN

(14) CALENDAR DAYS AFTER STRIPPING AND GRADING ACTIVITIES

HAVE CEASED IN THE AREA. MAINTENANCE SHALL BE PERFORMED

AS NECESSARY TO ENSURE CONTINUED STABILIZATION. (REQUIRE-

MENT MAY BE REDUCED TO SEVEN (7) DAYS FOR SENSITIVE AREAS.)

8.PRIOR TO REMOVAL OF SEDIMENT CONTROL MEASURES, THE

CONTRACTOR SHALL STABILIZE AND HAVE ESTABLISHED PER-

MANENT STABILIZATION FOR ALL CONTRIBUTORY DISTURBED

AREAS USING SOD OR AN APPROVED PERMANENT SEED MIXTURE

WITH REQUIRED SOIL AMENDMENTS AND AN APPROVED ANCHORED

MULCH. WOOD FIBER MULCH MAY ONLY BE USED IN SEEDING SEASON

WHERE THE SLOPE DOES NOT EXCEED 10% AND GRADING HAS BEEN

DONE TO PROMOTE SHEET FLOW DRAINAGE. AREAS BROUGHT TO

FINISHED GRADE DURING THE SEEDING SEASON SHALL BE PERMA-

NENTLY STABILIZED AS SOON AS POSSIBLE, BUT NOT LATER THAN

FOURTEEN (14) CALENDAR DAYS AFTER ESTABLISHMENT. WHEN

PROPERTY IS BROUGHT TO FINISHED GRADE DURING THE MONTHS

OF NOVEMBER THROUGH FEBRUARY, AND PERMANENT STABILI-

ZATION IS FOUND TO BE IMPRACTICAL, TEMPORARY SEED AND

ANCHORED STRAW MULCH SHALL BE APPLIED TO DISTURBED

AREAS. THE FINAL PERMANENT STABILIZATION OF SUCH PROPER-

TY SHALL BE APPLIED BY MARCH 15 OR EARLIER IF GROUND AND

WEATHER CONDITIONS ALLOW.

9.THE SITE’S APPROVAL LETTER, APPROVED EROSION AND

SEDIMENT CONTROL PLANS, DAILY LOG BOOKS, AND TEST

REPORTS SHALL BE AVAILABLE AT THE SITE FOR INSPECTION

BY DULY AUTHORIZED OFFICIALS OF WMA AND ATC RESPON-

SIBLE FOR PROJECT.

10.SURFACE DRAINAGE FLOWS OVER UNSTABILIZED CUT AND FILL SLOPES

SHALL BE CONTROLLED BY EITHER PREVENTING DRAINAGE FLOWS FROM

TRAVERSING THE SLOPES OR BY INSTALLING PROTECTIVE DEVICES TO

LOWER THE WATER DOWNSLOPE WITHOUT CAUSING EROSION. DIKES

SHALL BE INSTALLED AND MAINTAINED AT THE TOP OF A CUT OR FILL

SLOPE UNTIL THE SLOPE AND DRAINAGE AREA TO IT ARE FULLY STAB-

ILIZED, AT WHICH TIME THEY MUST BE REMOVED AND FINAL GRADING

DONE TO PROMOTE SHEET FLOW DRAINAGE. PROTECTIVE METHODS

MUST BE PROVIDED AT POINTS OF CONCENTRATED FLOW WHERE ERO-

SION IS LIKELY TO OCCUR.

11. PERMANENT SWALES OR OTHER POINTS OF CONCENTRATED WATER

FLOW SHALL BE STABILIZED WITH SOD OR SEED WITH AN APPROVED

EROSION CONTROL MATTING, RIP-RAP, OR BY OTHER APPROVED

STABILIZATION MEASURES.

12.TEMPORARY SEDIMENT CONTROL DEVICES MAY BE REMOVED,

WITH PERMISSION OF WMA INSPECTOR AND ATC INSPECTORS,

WITHIN THIRTY (30) DAYS FOLLOWING ESTABLISHMENT OF

PERMANENT STABILIZATION IN ALL CONTRIBUTORY DRAINAGE

AREAS. STORMWATER MANAGEMENT STRUCTURES USED

TEMPORARILY FOR SEDIMENT CONTROL SHALL BE CONVERTED

TO THE PERMANENT CONFIGURATION WITHIN THIS TIME PERIOD

AS WELL.

13.NO PERMANENT CUT OR FILL SLOPE WITH A GRADIENT STEEPER THAN

3:1 WILL BE PERMITTED IN LAWN MAINTENANCE AREAS. A SLOPE

GRADIENT OF UP TO 2:1 WILL BE PERMITTED IN NON-MAINTENANCE

AREAS PROVIDED THAT THOSE AREAS ARE INDICATED ON THE

EROSION AND SEDIMENT CONTROL PLAN WITH A LOW-MAINTENANCE

GROUND COVER SPECIFIED FOR PERMANENT STABILIZATION. SLOPE

GRADIENT STEEPER THAN 2:1 WILL NOT BE PERMITTED WITH

VEGETATIVE STABILIZATION.

FOR FINISHED GRADING, THE CONTRACTOR SHALL PROVIDE

ADEQUATE GRADIENTS TO PREVENT WATER FROM PONDING

FOR MORE THAN TWENTY FOUR (24) HOURS AFTER THE END

OF A RAINFALL EVENT. DRAINAGE COURSES AND SWALE FLOW

AREAS MAY TAKE AS LONG AS FORTY-EIGHT (48) HOURS AFTER

THE END OF A RAINFALL EVENT TO DRAIN. AREAS DESIGNED TO

HAVE STANDING WATER SHALL NOT BE REQUIRED TO MEET THIS

REQUIREMENT.

DISTURBED FOR MORE THAN ONE DAY.

22.

WHERE DEEMED APPROPRIATE BY THE ENGINEER OR INSPECTOR,

SEDIMENT BASINS AND TRAPS MAY NEED TO BE SURROUNDED

WITH AN APPROVED SAFETY FENCE. THE FENCE MUST CONFORM

TO LOCAL ORDINANCES AND REGULATIONS. THE DEVELOPER OR

OWNER SHALL CHECK WITH LOCAL BUILDING OFFICIALS ON APPLI-

CABLE SAFETY REQUIREMENTS. WHERE SAFETY FENCE IS DEEMED

APPROPRIATE AND LOCAL ORDINANCES DO NOT SPECIFY FENCING

SIZES AND TYPES, THE FOLLOWING SHALL BE USED AS A MINIMUM

STANDARD: THE SAFETY FENCE MUST BE MADE OF WELDED WIRE

AND AT LEAST 42 INCHES HIGH, HAVE POSTS SPACED NO FARTHER

APART THAN 8 FEET, HAVE MESH OPENINGS NO GREATER THAN 2

INCHES IN WIDTH AND 4 INCHES IN HEIGHT WITH A MINIMUM OF 14

GAUGE WIRE. SAFETY FENCE MUST BE MAINTAINED AND IN GOOD

CONDITION AT ALL TIMES.

23.

OFF-SITE SPOIL OR BORROW AREAS ON STATE OR FEDERAL

PROPERTY MUST HAVE PRIOR APPROVAL BY WMA AND OTHER

APPLICABLE STATE, FEDERAL, AND LOCAL AGENCIES; OTHER-

WISE APPROVAL MUST BE GRANTED BY THE LOCAL AUTHORITIES.

ALL WASTE AND BORROW AREAS OFF-SITE MUST BE PROTECTED

BY SEDIMENT CONTROL MEASURES AND STABILIZED.

24.

25.SITES WHERE INFILTRATION DEVICES ARE USED FOR THE

CONTROL OF STORMWATER, EXTREME CARE MUST BE TAKEN

TO PREVENT RUNOFF FROM UNSTABILIZED AREAS FROM

ENTERING THE STRUCTURE DURING CONSTRUCTION. SEDIMENT

CONTROL DEVICES PLACED IN INFILTRATION AREAS MUST HAVE

BOTTOM ELEVATIONS AT LEAST TWO (2) FEET HIGHER THAN THE

FINISH GRADE BOTTOM ELEVATION OF THE INFILTRATION PRAC-

TICE. WHEN CONVERTING A SEDIMENT TRAP TO AN INFILTRATION

DEVICE, ALL ACCUMULATED SEDIMENT MUST BE REMOVED AND

DISPOSED OF PRIOR TO FINAL GRADING OF INFILTRATION DEVICE.

26.WHEN A STORM DRAIN SYSTEM OUTFALL IS DIRECTED TO A

SEDIMENT TRAP OR SEDIMENT BASIN AND THE SYSTEM IS TO

BE USED FOR TEMPORARILY CONVEYING SEDIMENT LADEN

WATER, ALL STORM DRAIN INLETS IN NON-SUMP AREAS SHALL

HAVE TEMPORARY ASPHALT BERMS CONSTRUCTED AT THE

TIME OF BASE PAVING TO DIRECT GUTTER FLOW INTO THE

INLETS TO AVOID SURCHARGING AND OVERFLOW OF INLETS

IN SUMP AREAS.
