MULCH AND SEED SPECIFICATIONS

SUMMARY OF TEMPORARY AND PERMANENT MULCH APPLICATION REQUIREMENTS

TEMPORARY

WITHIN 100 FEET OF WETLANDS

AND WATERBODIES

APPLY STRAW MULCH AT A MINIMUM OF 70 LBS/1000 S.F. OF EXPOSED SOIL.* MUST BE DONE WITHIN 48 HOURS OF INITIAL

SOIL DISTURBANCE AND BEFORE FORECASTED STORM EVENTS, UNLESS OTHERWISE SPECIFIED. IF FINAL RESTORATION IS

NOT SCHEDULED WITHIN 30 DAYS, APPLY ANNUAL RYEGRASS AT 1LB/1000 S.F.

OTHER AREAS OF EXPOSED SOIL

WITH SLOPES LESS THAN 8% AND

SOILS STOCKPILES

IF NO ACTIVITY IS SCHEDULED WITHIN 30 DAYS, APPLY STRAW MULCH AT A MINIMUM OF 70 LBS/1000 S.F. OF EXPOSED

SOIL*, UNLESS SPECIFIED OTHERWISE. ECM** MAY BE USED. STRAW MULCH MAY ALSO BE SUPPLEMENTED BY

TEMPORARY SEEDING WITH ANNUAL RYEGRASS AT 1 LB/1000 S.F. FOR AREAS WHERE ADDITIONAL ACTIVITY IS NOT

EXPECTED FOR SEVERAL MORE WEEKS. AN EROSION CONTROL BARRIER MUST BE INSTALLED AROUND SOIL STOCKPILES

THAT ARE EXPECTED TO REMAIN UNDISTURBED FOR MORE THAN 48 HOURS, OR PRIOR TO A STORM EVENT.

OTHER AREAS OF EXPOSED SOIL

WITH SLOPES GREATER THAN 8%

IF FINAL RESTORATION IS NOT SCHEDULED WITHIN 30 DAYS OR PRIOR TO A STORM EVENT, APPLY STRAW MULCH AT THE

ABOVE RATES.* HAY OR STRAW MUST BE ANCHORED, UNLESS SPECIFIC SITE CONDITIONS DO NOT REQUIRE USE OF

ANCHORING. ECM** OR MATTING MAY ALSO BE USED. TEMPORARY SEEDING WITH ANNUAL RYEGRASS AT 1LB/1000 S.F. IS

ALSO RECOMMENDED FOR AREAS WHERE FINAL STABILIZATION IS NOT EXPECTED FOR SEVERAL MORE WEEKS.

TEMPORARY SEEDBED

PREPARATION

APPLY LIMESTONE AND FERTILIZER (UPLANDS ONLY) ACCORDING TO SOIL TEST DATA. IF SOIL TEST IS NOT POSSIBLE,

10-0-10 FERTILIZER MAY BE APPLIED AT A RATE OF 600 LBS/ACRE AND LIMESTONE AT 3 TONS/ACRE. LOOSEN COMPACTED

SOILS.

TEMPORARY SEEDING IN

WETLANDS

IF REQUIRED, APPLY ANNUAL RYEGRASS AT A RATE OF 1 LB/1000 S.F. AND COVER WITH STRAW MULCH. DO NOT ADD LIME

OR FERTILIZER TO WETLANDS.

FINAL RESTORATION

PERMANENT MULCHING EROSION CONTROL MIX (ECM) CAN BE USED AS A TEMPORARY OR PERMANENT SLOPE REINFORCEMENT AND LEFT TO

RE-VEGETATE TO NEAR NATURAL CONDITIONS. IT IS NOT USED WHERE GRASS VEGETATION IS REQUIRED.

RE-VEGETATION CAN BE ENHANCED BY SEEDING, WHICH IS ENCOURAGED IF USED AS A PERMANENT STABILIZATION

MEASURE. PERMANENT MULCH MUST NOT BE USED IN AREAS OF CONCENTRATED WATER FLOWS AND EVIDENCE OF

GROUNDWATER SEEPAGE ON SLOPES MAY REQUIRE THE ECM TO BE REPLACED WITH RIPRAP.

ON SLOPES THAT ARE 3H:1V OR LESS, ECM SHALL BE APPLIED AT A MINIMUM OF 2 INCHES THICK PLUS AN ADDITIONAL 1/2

INCH PER 20 FEET OF SLOPE UP TO 100 FEET (E.G. 3 INCHES THICK FOR 60 FEET OF SLOPE; 4 INCHES THICK FOR 100 FEET

OF SLOPE).

FOR SLOPES BETWEEN 3H:1V AND 2H:1V, ECM WILL BE APPLIED 4 INCHES THICK PLUS AN ADDITIONAL 1/2 INCH PER 20 FEET

OF SLOPE UP TO 100 FEET (E.G. 5 INCHES THICK FOR 60 FEET OF SLOPE; 6 INCHES THICK FOR 100 FEET OF SLOPE)

ECM MUST BE SPREAD EVENLY AND MUST PROVIDE 100 PERCENT SOIL COVERAGE.

PERMANENT RE-VEGETATION PERMANENT SEEDING SHALL BE USED ON ALL EXPOSED SOIL THAT IS NOT PERMANENTLY STABILIZED BY ROCK, GRAVEL

OR ECM. THE FOLLOWING PERMANENT SEEDING MIX SPECIFICATIONS ARE BETWEEN APRIL 16 AND OCTOBER 31,

HOWEVER WINTER RYE WILL BE ADDED TO THE PERMANENT SEED MIX AFTER OCTOBER 1. PERMANENT SEEDING IS NOT

REQUIRED DURING THE WINTER CONSTRUCTION SEASON, ALTHOUGH DORMANT SEEDING MAY BE PERFORMED

THE CONTRACTOR WILL BE RESPONSIBLE FOR THE PROPER MAINTENANCE OF ALL RE-VEGETATED AREAS UNTIL THE PROJECT HAS BEEN COMPLETED AND

ACCEPTED. FOLLOWING FINAL SEEDING THE CONTRACTOR WILL INSPECT RESTORED AREAS EVERY 30 DAYS UNTIL 75 PERCENT VEGETATIVE COVER HAS

BEEN ESTABLISHED UNLESS ADJACENT, UNDISTURBED AREAS INDICATE THAT ACHIEVING THAT LEVEL OF VEGETATION IN THE AREA IS UNLIKELY. WHERE

SEEDED AREAS HAVE BECOME ERODED OR DAMAGED BY CONSTRUCTION OPERATIONS, OR WHERE POOR GERMINATION IS OBSERVED, THE AFFECTED AREAS

WILL BE PROMPTLY RE-GRADED, LIMED, FERTILIZED, AND RE-SEEDED AS NEEDED UNTIL THE ABOVE CRITERIA ARE MET. THE CONTRACTOR MAY BE REQUIRED

TO RE-SEED DURING THE FOLLOWING SPRING IN ORDER TO ACHIEVE THE REQUIRED VEGETATIVE COVER.

* MULCH APPLICATION RATES SHALL BE DOUBLED FOR WINTER CONSTRUCTION

GENERAL EROSION CONTROL NOTES

INSTALL EROSION CONTROL MEASURES IN ACCORDANCE WITH THE

SPECIFICATIONS HEREIN AND IN ACCORDANCE WITH ALL MASSACHUSETTS

REGULATIONS.

1. INSTALL ALL PERIMETER CONTROLS PRIOR TO COMMENCEMENT OF EARTH

MOVING ACTIVITIES.

2. PRIOR TO THE INITIATION OF GRADING OPERATIONS, CONSTRUCT AND

STABILIZE TEMPORARY DRAINAGE SWALES, CHECK DAMS, AND PLUNGE

POOLS AS NEEDED TO EFFECTIVELY CONTROL EROSION AND PREVENT

TRANSPORT OF SEDIMENT INTO REGULATED RESOURCES OR OFF-SITE.

3. DRAINAGE CHANNELS SHALL BE STABILIZED PRIOR TO RECEIVING RUNOFF.

STABILIZE ROAD DITCHES WITH LOAM, SEED, EROSION CONTROL

BLANKETS OR RIPRAP (DEPENDING ON SLOPE) WITHIN 24 HOURS OF FINAL

GRADING.

4. INSTALL STONE CHECK DAMS WITHIN 24 HOURS OF ROUGH OR FINISH

GRADING ANY SECTION OF DITCH, AS SHOWN ON THE PROJECT PLANS

AND AT OTHER LOCATIONS AS NEEDED.

5. ALL ROADWAYS AND CUT/FILL SLOPES SHALL BE STABILIZED WITHIN 72

HOURS OF ACHIEVING FINISHED GRADE.

6. ONCE A WEEK, OR AFTER RAINSTORMS PRODUCING AT LEAST 1/2 INCH OF

RAINFALL, WHICHEVER IS MORE FREQUENT, INSPECT ALL AREAS WHERE

TEMPORARY NON-STRUCTURAL MEASURES ARE USED. THE INSPECTION

SCHEDULE WILL BE INCREASED TO DAILY DURING THE WINTER

CONSTRUCTION PERIOD.

7. AFTER GRADING AND PRIOR TO FINAL STABILIZATION PROVIDE PERIODIC

APPLICATION OF WATER OR CALCIUM CHLORIDE AS NEEDED TO CONTROL

EXCESSIVE DUST.

8. REMOVE TEMPORARY EROSION CONTROL MEASURES ONCE AN AREA OF

THE SITE IS PERMANENTLY STABILIZED.

9. MONITOR PUBLIC ROADS FOR SIGNS OF MUD TRACKING OR SPILLAGE OF

SPOIL MATERIAL. CLEAN ROADWAYS AS NEEDED.

1. PREPARE SOIL BEFORE INSTALLING BLANKETS, INCLUDING ANY NECESSARY

APPLICATION OF LIME, FERTILIZER, AND SEED. NOTE: WHEN USING CELL-O- SEED

DO NOT SEED PREPARED AREA. CELL-O-SEED MUST BE INSTALLED WITH

PAPER SIDE DOWN.

2. BEGIN AT THE TOP OF THE SLOPE BY ANCHORING THE BLANKET IN A 6" DEEP X

6" WIDE TRENCH WITH APPROXIMATELY 12" OF BLANKET EXTENDED BEYOND THE

UP-SLOPE PORTION OF THE TRENCH. ANCHOR THE BLANKET WITH A ROW OF

STAPLES/STAKES APPROXIMATELY 12" APART IN THE BOTTOM OF THE TRENCH.

BACKFILL AND COMPACT THE TRENCH AFTER STAPLING. APPLY SEED TO

COMPACTED SOIL AND FOLD REMAINING 12" PORTION OF BLANKET BACK OVER

SEED AND COMPACTED SOIL. SECURE BLANKET OVER COMPACTED SOIL WITH A

ROW OF STAPLES/STAKES SPACED APPROXIMATELY 12" APART ACROSS THE

WIDTH OF THE BLANKET.

3. ROLL THE BLANKETS (A.) DOWN OR (B.) HORIZONTALLY ACROSS THE SLOPE.

BLANKETS WILL UNROLL WITH APPROPRIATE SIDE AGAINST THE SOIL SURFACE.

ALL BLANKETS MUST BE SECURELY FASTENED TO SOIL SURFACE BY PLACING

STAPLES/STAKES IN APPROPRIATE LOCATIONS AS SHOWN IN THE STAPLE

PATTERN GUIDE. WHEN USING OPTIONAL DOT SYSTEM, STAPLES/STAKES

SHOULD BE PLACED THROUGH EACH OF THE COLORED DOTS CORRESPONDING

TO THE APPROPRIATE STAPLE PATTERN.

4. THE EDGES OF PARALLEL BLANKETS MUST BE STAPLED WITH APPROXIMATELY

2"-5" OVERLAP DEPENDING ON BLANKET TYPE. TO ENSURE PROPER SEAM

ALIGNMENT, PLACE THE EDGE OF THE OVERLAPPING BLANKET (BLANKET BEING

INSTALLED ON TOP) EVEN WITH THE COLORED SEAM STITCH ON THE

PREVIOUSLY INSTALLED BLANKET.

5. CONSECUTIVE BLANKETS SPLICED DOWN THE SLOPE MUST BE PLACED END

OVER END (SHINGLE STYLE) WITH AN APPROXIMATE 3" OVERLAP. STAPLE

THROUGH OVERLAPPED AREA, APPROXIMATELY 12" APART ACROSS ENTIRE

BLANKET WIDTH.

NOTE: *IN LOOSE SOIL CONDITIONS, THE USE OF STAPLE OR STAKE LENGTHS

GREATER THAN 6" MAY BE NECESSARY TO PROPERLY SECURE THE BLANKETS.
