1. THE EROSION CONTROL PLANS IN THIS SET SHALL BE REVIEWED AND

IMPLEMENTED BY THE CONTRACTOR PRIOR TO COMMENCEMENT OF

WORK.

2. THE CONTRACTOR SHALL ENSURE ALL MONITORING AND INSPECTIONS

ARE PERFORMED AS REQUIRED ONSITE THROUGHOUT CONSTRUCTION.

3. NO LAND CLEARING, GRADING OR EXCAVATION SHALL BE DONE

BETWEEN OCTOBER 15TH AND APRIL 15TH. ANY DEVIATION FROM THIS

CONDITION REQUIRES REVIEW AND APPROVAL OF A SEPARATE WINTER

EROSION CONTROL PLAN BY ENVIRONMENTAL PLANNING PRIOR TO

BEGINNING CONSTRUCTION. THE DEVELOPER SHALL BE RESPONSIBLE

FOR IMPLEMENTING AND MAINTAINING SITE EROSION CONTROL AT ALL

TIMES.

4. IT SHALL BE THE RESPONSIBILITY OF THE OWNER AND THE PERMITTEE

TO ENSURE THAT EROSION DOES NOT OCCUR FROM ANY ACTIVITY

DURING OR AFTER PROJECT CONSTRUCTION. ADDITIONAL MEASURES,

BEYOND THOSE SPECIFIED, MAY BE REQUIRED BY THE PLANNING

DIRECTOR AS DEEMED NECESSARY TO CONTROL ACCELERATED

EROSION.

5. PRIOR TO ANY FORECAST RAIN AND ANYTIME BETWEEN OCTOBER 15

AND APRIL 15, AT THE END OF EACH WORKDAY, AT THE END OF EACH

WORKWEEK, THE DEVELOPER SHALL IMPLEMENT ALL TEMPORARY

MEASURES NECESSARY TO PREVENT EROSION AND SILTATION, UNTIL

THE PROJECT HAS BEEN FINALIZED. THESE MEASURES SHALL INCLUDE,

BUT NOT BE LIMITED TO, DIRECT SEEDING OF THE AFFECTED AREAS,

STRAW MULCHING, AND/OR INSTALLATION OF STRAW BALES DAMS/SILT

FENCES.

6. DURING CONSTRUCTION, NO TURBID WATER SHALL BE PERMITTED TO

LEAVE THE SITE. USE OF SILT AND GREASE TRAPS, FILTER BERMS, HAY

BALES OR SILT FENCES SHALL BE USED TO PREVENT SUCH DISCHARGE.

7. ALL AREAS ON- AND OFF-SITE EXPOSED DURING CONSTRUCTION

ACTIVITIES, IF NOT PERMANENTLY LANDSCAPED PER PLAN, SHALL BE

PROTECTED BY MULCHING AND/OR SEEDING WITH ANNUAL WINTER

BARLEY.

8. ALL EXCAVATED MATERIAL SHALL BE REMOVED TO AN APPROVED

DISPOSAL SITE OR DISPOSED OF ON-SITE IN A MANNER THAT WILL NOT

CAUSE EROSION.

9. ANY MATERIAL STOCKPILED, FOR LONGER THAN 14 DAYS, DURING

CONSTRUCTION SHALL BE COVERED WITH PLASTIC.

10. UPON COMPLETION OF CONSTRUCTION, ALL REMAINING EXPOSED SOILS

SHALL BE PERMANENTLY REVEGETATED PER LANDSCAPING PLAN. THE

PROTECTION SHALL BE INSTALLED PRIOR TO CALLING FOR FINAL

APPROVAL OF THE PROJECT AND AT ALL TIMES BETWEEN OCTOBER 15

AND APRIL 15. SUCH PROTECTION SHALL BE MAINTAINED FOR AT LEAST

ONE WINTER UNTIL PERMANENT PROTECTION IS ESTABLISHED.

11. EXPOSED SOIL ON SLOPES GREATER THAN 20% SHALL BE SEEDED,

COVERED WITH 2 INCHES OF STRAW, AND AN EROSION CONTROL

BLANKET. THE EROSION CONTROL BLANKET SHALL BE STAKED IN

PLACE.

12. IT IS THE DEVELOPER'S RESPONSIBILITY TO SEE THAT ADDITIONAL

MEASURES, NECESSARY TO CONTROL SITE EROSION AND PREVENT

FIBER ROLLS

NTS

FIBER ROLLS CONSTRUCTION SPECIFICATIONS

1. PREPARE SLOPE BEFORE THE FIBER ROLL PROCEDURE IS STARTED.

SHALLOW GULLIES SHOULD BE SMOOTHED AS WORK PROGRESSES.

2. DIG SMALL TRENCHES ACROSS SLOPE ON CONTOUR, TO PLACE FIBER

ROLLS IN. THE TRENCH SHOULD BE DEEP ENOUGH TO ACCOMMODATE

HALF THE THICKNESS OF THE FIBER ROLL. WHEN THE SOIL IS LOOSE AND

UNCOMPACTED, THE TRENCH SHOULD BE DEEP ENOUGH TO BURY THE

FIBER ROLL 2/3 OF ITS THICKNESS BECAUSE THE GROUND WILL SETTLE.

IT IS CRITICAL THAT FIBER ROLLS ARE INSTALLED PERPENDICULAR TO

WATER MOVEMENT, PARALLEL TO THE SLOPE CONTOUR.

3. START BUILDING TRENCHES AND INSTALL FIBER ROLLS FROM THE

BOTTOM OF THE SLOPE AND WORK UP.

4. CONSTRUCT TRENCHES AT CONTOUR INTERVALS OF THREE TO EIGHT

FEET APART DEPENDING ON STEEPNESS OF SLOPE. THE STEEPER THE

SLOPE, THE CLOSER TOGETHER THE TRENCHES.

5. LAY THE FIBER ROLL ALONG THE TRENCHES FITTING IT SNUGLY AGAINST

THE SOIL. MAKE SURE NO GAPS EXIST BETWEEN THE SOIL AND THE

FIBER ROLL. USE A STRAIGHT BAR TO DRIVE HOLES THROUGH THE FIBER

ROLL AND INTO THE SOIL FOR THE WOODEN STAKES.

6. DRIVE THE STAKE THROUGH THE PREPARED HOLE INTO THE SOIL. LEAVE

ONLY ONE OR TWO INCHES OF STAKE EXPOSED ABOVE FIBER ROLL. IF

USING WILLOW STAKES REFER TO USDA SOIL CONSERVATION SERVICE

TECHNICAL GUIDE, BIOENGINEERING, FOR GUIDELINES TO PREPARING

LIVE WILLOW MATERIAL.

7. INSTALL STAKES AT LEAST EVERY FOUR FEET APART THROUGH FIBER

ROLL. ADDITIONAL STAKES MAY BE DRIVEN ON THE DOWNSLOPE SIDE OF

THE TRENCHES ON HIGHLY EROSIVE OR VERY STEEP SLOPES.

INSTALLATION AND MAINTENANCE

8. INSPECT THE FIBER ROLL AND THE SLOPES AFTER SIGNIFICANT STORMS.

MAKE SURE THE FIBER ROLLS ARE IN CONTACT WITH THE SOIL.

9. REPAIR ANY RILLS OR GULLIES PROMPTLY.
