INSTALLATION:
WHEN INSTALLING RUNNING LENGTHS OF WATTLES, BUTT THE SECOND
WATTLE TIGHTLY AGAINST THE FIRST, DO NOT OVERLAP THE ENDS. STAKE
THE WATTLES AT EACH END AND FOUR FOOT ON CENTER. FOR EXAMPLE:
A 25 FOOT WATTLE USES 6 STAKES
A 20 FOOT WATTLE USES 5 STAKES
A 12 FOOT WATTLE USES 4 STAKES
STAKES SHOULD BE DRIVEN THROUGH THE MIDDLE OF THE WATTLE.
LEAVING 2 - 3 INCHES OF THE STAKE PROTRUDING ABOVE THE WATTLE. A
HEAVY SEDIMENT LOAD WILL TEND TO PICK THE WATTLE UP AND COULD
PULL IT OFF THE STAKES IF THEY ARE DRIVEN DOWN TOO LOW. IT MAY BE
NECESSARY TO MAKE A HOLE IN THE WATTLE WITH A PICK END OF YOUR
MADDOX IN ORDER TO GET THE STAKE THROUGH THE STRAW. WHEN
STRAW WATTLES ARE USED FOR FLAT GROUND APPLICATIONS, DRIVE THE
STAKES STRAIGHT DOWN; WHEN INSTALLING WATTLES ON SLOPES, DRIVE
THE STAKES PERPENDICULAR TO THE SLOPE.
DRIVE THE FIRST END STAKE OF THE SECOND WATTLE AT AN ANGLE
TOWARD THE FIRST WATTLE IN ORDER TO HELP ABUT THEM TIGHTLY
TOGETHER. IF YOU HAVE DIFFICULTY DRIVING THE STAKE INTO EXTREMELY
HARD OR ROCKY SLOPES, A PILOT BAR MAY BE NEEDED TO BEGIN THE

W1 & W2 INSTALLATION NOTES:
1. THE LOCATION AND LENGTH OF WATTLE IS DEPENDENT ON THE CONDITIONS OF EACH SITE.
2. WATTLES SHALL BE INSTALLED PRIOR TO ANY LAND-DISTURBING ACTIVITIES.
3. WATTLES SHALL CONSIST OF STRAW, COMPOST, EXCELSIOR, OR COCONUT FIBER.
4. NOT FOR USE IN CONCENTRATED FLOW AREAS.
5. THE WATTLES SHALL BE TRENCHED INTO THE GROUND A MINIMUM OF TWO (2) INCHES.
6. WATTLES SHALL BE INSTALLED PER MANUFACTURERS SPECIFICATIONS.
7. ON SLOPES, WATTLES SHOULD BE INSTALLED ON CONTOUR WITH A SLIGHT DOWNWARD ANGLE AT THE END OF THE ROW IN ORDER TO PREVENT
PONDING AT THE MID SECTION.
8. RUNNING LENGTHS OF WATTLES SHOULD BE ABUTTED FIRMLY TO ENSURE NO LEAKAGE AT THE ABUTMENTS.
9. SPACING - DOWNSLOPE:
VERTICAL SPACING FOR SLOPE INSTALLATIONS SHOULD BE DETERMINED BY SITE CONDITIONS. SLOPE GRADIENT AND SOIL TYPE ARE THE MAIN
FACTORS. A GOOD RULE OF THUMB IS:
1:1 SLOPES = 10 FEET APART
2:1 SLOPES = 20 FEET APART
3:1 SLOPES = 30 FEET APART
4:1 SLOPES = 40 FEET APART, ETC.
HOWEVER, ADJUSTMENTS MAY HAVE TO BE MADE FOR THE SOIL TYPE: FOR SOFT, LOAMY SOILS - ADJUST THE ROWS CLOSER TOGETHER;
FOR HARD, ROCKY SOILS - ADJUST THE ROWS FURTHER APART. A SECONDARY WATTLE PLACED BEHIND THE ABUTMENT OF TWO WATTLES IS
ENCOURAGED ON STEEP SLOPES OR WHERE JOINTS HAVE FAILED IN THE PAST.
10. STAKING: THE CITY RECOMMENDS USING WOOD STAKES TO SECURE THE WATTLES. 1/2" TO 5/8" REBAR IS ALSO ACCEPTABLE. BE SURE TO USE A
STAKE THAT IS LONG ENOUGH TO PROTRUDE SEVERAL INCHES ABOVE THE WATTLE: 18" IS A GOOD LENGTH FOR HARD, ROCKY SOIL. FOR SOFT
LOAMY SOIL USE A 24" STAKE.
4"-6" ABOVE WATTLE AFTER BAILING WIRE
OR NYLON ROPE IS ATTACHED. STAKES
NEED TO BE TAMPED UNTIL WIRE/ROPE IS
SNUG WITH WATTLE.

2.THIS EROSION CONTROL PLAN SERVES ONLY AS A GUIDELINE TO THE CONTRACTOR.
STAGING/PHASING OF THE BMPs SHOWN ON THIS PLAN IS EXPECTED. ADDITIONAL
AND/OR DIFFERENT BMPs FROM THOSE SHOWN MAY BE NECESSARY DURING
CONSTRUCTION DUE TO CHANGING SITE CONDITIONS OR AS REQUIRED BY LOCAL
AUTHORITIES. IN NO WAY SHALL THIS PLAN REPLACE THE CONTRACTOR'S
OBLIGATIONS FOR PERMITTING (CITY, STATE DISCHARGE PERMIT, ETC.) OR
COMPLIANCE WITH GOVERNING AUTHORITIES. IT SHALL BE THE RESPONSIBILITY OF
THE CONTRACTOR (OR PERMIT HOLDER) TO ENSURE EROSION CONTROL MEASURES
ARE PROPERLY MAINTAINED AND FOLLOWED.
3.CONTRACTOR SHALL IMPLEMENT THE APPROPRIATE MEASURES ACCORDING TO THE

4.THIS EROSION CONTROL PLAN IS SCHEMATIC IN NATURE. AS SUCH, GRAPHICAL
SYMBOLS MAY NOT BE TO SCALE, NOR ARE THEY NECESSARILY SHOWN IN THEIR
EXACT LOCATION.
5.CONTRACTOR SHALL IMPLEMENT APPROPRIATE INLET PROTECTION FOR ALL AREA
DRAINS UNTIL SITE IS FULLY STABILIZED.
6.INLET PROTECTION SHALL BE ADAPTED, AS NECESSARY, TO THE SURROUNDING
SURFACE TYPE AND CONDITION (i.e., STAKE-DRIVEN WATTLES FOR BARE SOIL, SAND
BAGS OR GRAVEL SOCKS FOR PAVEMENT, ETC.)
7.CONTRACTOR SHALL LIMIT SEDIMENT DEPOSITION IN THE DETENTION POND DURING
CONSTRUCTION. ANY ACCUMULATED SEDIMENT SHALL BE REMOVED AND DISPOSED
OF IN AN ACCEPTABLE MANNER. ALL POND COMPONENTS SHALL BE RESTORED TO
DESIGN ELEVATIONS AND INTENT PRIOR TO INITIAL ACCEPTANCE.
8.CONTRACTOR IS RESPONSIBLE FOR STABILIZING ALL SLOPES, PARTICULARLY
THOSE STEEPER THAN 6:1. CRIMP MULCHING, HYDRO MULCHING, EROSION MATS,

approved project schedule, construction plans, and erosion control report.
4. At all times during construction, the Developer shall be responsible for preventing and controlling on-site erosion including keeping the
property sufficiently watered so as to minimize wind blown sediment. The Developer shall also be responsible for installing and maintaining
all erosion control facilities shown herein.
5. Pre-disturbance vegetation shall be protected and retained wherever possible. Removal or disturbance of existing vegetation shall be
limited to the area(s) required for immediate construction operations, and for the shortest practical period of time.
6. All soils exposed during land disturbing activity (stripping, grading, utility installations, stockpiling, filling, etc.) shall be kept in a roughened
condition by ripping or disking along land contours until mulch, vegetation, or other permanent erosion control BMPs are installed. No soils
in areas outside project street rights-of-way shall remain exposed by land disturbing activity for more than thirty (30) days before required
temporary or permanent erosion control (e.g. seed/mulch, landscaping, etc.) is installed, unless otherwise approved by the City/County.
7. In order to minimize erosion potential, all temporary (structural) erosion control measures shall:
a. Be inspected at a minimum of once every two (2) weeks and after each significant storm event and repaired or reconstructed as
necessary in order to ensure the continued performance of their intended function.
b. Remain in place until such time as all the surrounding disturbed areas are sufficiently stabilized as determined by the erosion control
inspector.
c. Be removed after the site has been sufficiently stabilized as determined by the erosion control inspector.
8. When temporary erosion control measures are removed, the Developer shall be responsible for the clean up and removal of all sediment
and debris from all drainage infrastructure and other public facilities.
9. The contractor shall immediately clean up any construction materials inadvertently deposited on existing streets, sidewalks, or other public
rights of way, and make sure streets and walkways are cleaned at the end of each working day.
10. All retained sediments, particularly those on paved roadway surfaces, shall be removed and disposed of in a manner and location so as not
to cause their release into any waters of the United States.
11. No soil stockpile shall exceed ten (10) feet in height. All soil stockpiles shall be protected from sediment transport by surface roughening,
watering, and perimeter silt fencing. Any soil stockpile remaining after thirty (30) days shall be seeded and mulched.
12. The stormwater volume capacity of detention ponds will be restored and storm sewer lines will be cleaned upon completion of the project
and before turning the maintenance over to the City/County or Homeowners Association (HOA).
