THE UNDERLYING, LOAMY GLACIAL TILL. SLOPES RANGE FROM 0 TO
3 PERCENT.
CROSBY SOILS ARE TYPICALLY ADJACENT TO BROOKSTON AND
MIAMI SOILS. BROOKSTON SOILS HAVE A FINER TEXTURED A
HORIZON AND ARE IN DEPRESSIONS. MIAMI SOILS ARE ON HIGHER
POSITIONS THAN CROSBY SOILS AND HAVE A BROWN B HORIZON
THAT ARE FREE OF MOTTLES.
MmB2 MIAMI SERIES
THE MIAMI SERIES CONSISTS OF DEEP, WELL DRAINED SOILS ON
TILL PLAINS. PERMEABILITY IS MODERATE IN SUBSOIL AND
MODERATELY SLOW IN UNDERLYING MATERIAL. THESE SOILS FORMED
IN LESS THAN 20 INCHES OF LOESS AND IN THE UNDERLYING
GLACIAL TILL. SLOPES RANGE FROM 0 TO 18 PERCENT.
MIAMI SOILS ARE TYPICALLY ADJACENT TO BROOKSTON AND
CROSBY SOILS ON MANY LANDSCAPES. BROOKSTON SOILS HAVE A
MOLLIC SURFACE LAYER. CROSBY SOILS HAVE A YELLOWISH BROWN,

SEEDING NOTES:
1. ANY SEEDED AREAS THAT FAIL TO GERMINATE SHALL BE RESEEDED. THE CONTRACTOR
IS RESPONSIBLE FOR PERIODICALLY INSPECTING THE TEMPORARY SEEDED AREAS FOR
EROSION AND TO PROMPTLY RESEED THE AREA.
2. FERTILIZE FALL SEEDED WHEAT OR RYE SEEDINGS WITH 5OIbs /AC NITROGEN
IN FEBRUARY OR MARCH.
3. MULCH WOOD CELLULOSE FIBER MAY BE USED WHERE APPLICATION IS MADE BY
HYDRAULIC MULCHING AT THE RATE OF ONE TON PER ACRE. STRAW MULCH MAY BE USED
AND APPLIED UNIFORMLY IN A CONTINUOUS BLANKET AT THE RATE OF 2 TONS PER ACRE
WITHIN 24 HOURS AFTER SEEDING.
4. SEDIMENT CONTROL FABRIC FABRIC SHALL BE NON -WOVEN CONSTRUCTION COMPOSED
OF POLYPROPYLENE AND SHALL BE ULTRAVIOLET STABILIZED.
5. IF TEMPORARY SEEDING IS ESTABLISHED PRIOR TO PERMANENT SEEDING, THE MULCH
MAY BE ELIMINATED EXCEPT IN BARE AREAS.
6. IF GRADING OCCURS DURING DECEMBER, JANUARY OR FEBRUARY, NO SEEDING SHALL
TAKE PLACE UNTIL SPRING PLANTING TIME. ALL SEDIMENT FILTERS AND TRAPS SHALL BE
IN PLACE PRIOR TO BULK EARTHMOVING OR CLEARING.
7. ALL AREAS NOT RECEIVING PAVED SURFACES SHALL BE SEEDED WITH PERMANENT
SEED MIXTURE AS SOON AS GRADE IS ESTABLISHED. RESEEDING MAY BE REQUIRED
AFTER UTILITY COMPANIES HAVE COMPLETED ALL INSTALLATIONS.
8. ALL LOTS /OUTLOTS OR AREAS OF SITE WHERE GRADING HAS OCCURRED, AND WHERE NO
CONSTRUCTION IS EXPECTED TO OCCUR WITHIN 60 DAYS, SHALL BE FILLED WITH ADDITIONAL
ADDITIONAL 3" OF TOPSOIL AND SEEDED USING THE TEMPORARY SEEDING PROCESS.
9. DURING DRY WEATHER, KEEP LAWNS WATERED WITH SPRINKLERS OR OTHER APPROVED
METHODS. RESEED ANY AREAS NOT GERMINATING OR DAMAGED AT INTERVALS AS MAY BE
REQUIRED ACCORDING TO SEASONAL CONDITION. WATER GRASS AND EXECUTE NECESSARY
WEEDING UNTIL ACCEPTABLE AND FULL STAND OF TURF HAS BEEN ESTABLISHED. UPON
ACCEPTANCE BY THE OWNER, THE OWNER SHALL ASSUME MAINTENANCE OF THE LAWN
AREAS.
10. ALL DATES SHOWN ARE NOMINAL AND MAY BE VARIED WITH CONCURRENCE OF THE
LANDSCAPE ARCHITECT OR THE LOCAL SOIL CONSERVATIONIST.
SOIL EROSION CONTROL SEQUENCE:
THE FOLLOWING IS A UST IN SEQUENCE OF CONSTRUCTION ACTIVITIES TO CONTROL SOIL
EROSION:
1. CONTRACTOR SHALL INSTALL SEDIMENT TRAPS AND STRAW BALE FILTERS AS PART OF
INITIAL PHASE OF ANY WORK TO ENSURE MAXIMUM SILT RETENTION ON -SITE.
2. MASS GRADE THE SITE; SIDES OF SWALES, MOUNDS AND PONDS TO BE SEEDED AND
MULCHED IMMEDIATELY UPON COMPLETION. TEMPORARY SEEDING SHALL BE REQUIRED FOR
ALL SWALES AND DISTURBED AREAS THAT CANNOT BE FINAL SEEDED WITHIN A TIME PERIOD
THAT WILL PREVENT SLOPE EROSION. FOR TEMPORARY SEEDING, THE CONTRACTOR SHALL
UTILIZE A FAST GROWING SEED OF EITHER OATS, ANNUAL RYEGRASS, WHEAT OR RYE
DEPENDING ON TIME OF YEAR. DISTURBED AREAS SHALL BE KEPT TO A MINIMUM AT ALL
TIMES.
3. CONTRACTOR SHALL CONTROL DEBRIS ACCUMULATION ON ALL STREETS SURROUNDING
PROJECT BY INSTAWNG STONE SURFACE AT ALL LOCATIONS WHERE CONSTRUCTION TRAFFIC
LEAVES THE SITE. DUST SHALL BE KEPT TO A MINIMUM BY UTILIZING SPRINKLING, CALCIUM
CHLORIDE, VEGETA11VE COVER, SPRAY-ON ADHESIVES OR OTHER APPROVED METHODS.
4. MAINTAIN ALL FILTERS AND TRAPS DURING CONSTRUCTION TO PREVENT ANY BLOCKAGES
FROM ACCUMULATED SEDIMENT. ADDITIONAL SEEDING AND STRAW BALES MAY BE REQUIRED
5. CONTRACTOR SHALL INSTALL ALL SANITARY SEWERS, STORM SEWERS, SUBSURFACE
DRAINS AND WATER MAINS. DRAINAGE BARRIORS PER THIS SHEET SHALL BE INSTALLED AT ALL
6. ALL PROPOSED STREET AREAS SHALL BE PAVED AS SOON AS POSSIBLE AFTER
SUBGRADE IS PREPARED.
7. ALL DISTURBED AREAS SHALL BE SEEDED AND MULCHED AS SPECIFIED.
8. CONTRACTOR SHALL MAINTAIN ALL TEMPORARY EROSION CONTROL MEASURES
THROUGHOUT THE CONSTRUCTION PHASE OF THIS PROJECT. REMOVE ALL TEMPORARY
EROSION AND SEDIMENT CONTROLS ONLY WHEN THERE IS A SUFFICIENT GROWTH OF GROUND
COVER TO PREVENT FURTHER EROSION.
EROSION CONTROL BLANKET:
1. THE BLANKET SHALL BE OF CONSISTENT THICKNESS WITH THE STRAW EVENLY DISTRIBUTED
OVER THE EN11RE AREA OF THE MAT. THE BLANKET SHALL BE COVERED ON THE TOP SIDE
WITH POLYPROPYLENE NETTING HAVING AN APPROXIMATE 5/8" X 5/8" MESH, AND ON THE
BOTTOM WITH A POLYPROPYLENE NETTING WITH AN APPROXIMATE 1/4" X 1/4" MESH. THE
BLANKET SHALL BE SEWN TOGETHER WITH COTTON THREAD.
2. STRAW EROSION CONTROL BLANKET (OR LOW VELOCITY CHANNEL LINING) SHALL BE SC150
(ALL STRAW) AS MANUFACTURED BY NORTH AMERICAN GREEN, OR EQUIVALENT.
EROSION CONTROL BLANKET OR CHANNEL LINING SHALL HAVE THE FOLLOWING PROPERTIES:
A. MATERIAL CONTENT:

SITE PREPARATION:
1. SMOOTH GRADE AND COMPACT ALL AREAS TO BE COVERED WITH MAT.
2. REMOVE ALL ROCKS, DIRT CLODS, GRASS CLUMPS. TRASH AND OTHER DEBRIS
THAT WILL LIFT MAT FROM GROUND SURFACE.
ANCHOR TRENCHES:
1. THE MAT MUST BE ANCHORED AT THE UPSTREAM AND DOWNSTREAM ENDS OF THE
PROTECTED AREA AND INTERMITTENTLY IN BETWEEN.
2. EXCAVATE END TRENCHES TO A MINIMUM OF 12" DEEP AND 6" WIDE BEFORE PLACING MAT.
3. DIG INTERMITTENT CHECK SLOTS 6 DEEP BY 6' WIDE TRANSVERSE TO MAT AT
APPROXIMATELY 25' INTERVALS.
SEED ING:
1. SEED AND FERTILIZER SHALL BE SPREAD BEFORE MAT INSTALLATION. SEED TYPE,
FERTILIZER TYPE AND RATE OF APPLICATION SHALL COMPLY WITH SEEDING
SPECIFICATIONS.
MAT PLACEMENT:
1. UNROLL MAT FLAT SIDE AGAINST THE GROUND. UNROLL MAT IN DIRECTION PARALLEL
WITH DIRECTION OF WATER FLOW.
2. MAT SHOULD LAY FLAT. DO NOT PULL MAT TAUT OVER GROUND. PUWNG TAUT MAY
CAUSE MAT TO BRIDGE DEPRESSIONS IN THE SURFACE AND ALLOW EROSION UNDERNEATH
TO OCCUR.
3. BEGINNING AT UP OR DOWNSTREAM END BURY TRANSVERSE TERMINAL END OF MAT TO
SECURE AND PREVENT EROSION FLOW UNDERNEATH.
4. FOLD AND SECURE MAT SNUGLY INTO ALL TRANSVERSE CHECK SLOTS.
5. BACKFILL AND COMPACT TRENCHES AND CHECK SLOTS AFTER STAKING THE MAT IN
BOTTOM OF TRENCH SEE GROUND FASTENING.

MAT END OF WATER FLOW.
8. OVERLAP ADJACENT EDGES OF MAT BY 3" (MIN.) AND STAKE SEE GROUND FASTENING.
GROUND FASTENING:
1. METAL PINS OR WOOD STAKES ARE RECOMMENDED FOR ANCHORING MAT TO THE GROUND
SURFACE. METAL PINS SHOULD BE 3/16" DIAMETER STEEL WITH 1 -1/2" DIAMETER STEEL
WASHER SECURED AT HEAD OF PIN. WOOD STAKES SHOULD BE 1'x3" NOMINAL STOCK CUT
IN A TRIANGULAR SHAPE. STAKES SHOULD BE 9 TO 18" LONG DEPENDING ON SOIL DENSITY.
LONGER ANCHORS ARE REQUIRED FOR LOOSE SOILS.
2. NOTE THAT GROUND FASTENERS DIFFERENT FROM THOSE MENTIONED HERE MAY FUNCTION
INADEQUATELY. CARE MUST BE TAKEN TO ASSURE THAT FASTENERS HOLD MAT SECURELY
AT THE SURFACE AND HAVE SUFFICIENT GROUND PENETRATION TO RESIST PULLOUT.
3. STAKE MAT TO GROUND ON 3 TO 5 FOOT CENTERS. ADD EXTRA STAKES AT
DEPRESSIONS IN GROUND SURFACE WHERE MAT BRIDGES OVER TO ASSURE GROUND
CONFORMITY.
4. DRIVE WOOD STAKES TO WITHIN 3' OF GROUND SURFACE. DO NOT DRIVE FLUSH TO
SURFACE. STEEL OR PLASTIC PINS SHOULD BE DRIVEN FLUSH TO SURFACE.
5. IN ALL TRANSVERSE TERMINAL TRENCHES AND CHECK SLOTS, STAKE EACH MAT AT ITS
CENTER AND AT OVERLAPPED EDGES BEFORE BACKFIWNG AND COMPACTING.
6. STAKE OVERLAPS LONGITUDINALLY AT 3' INTERVALS.
