NOTES:
1. A CHECK DAM IS A SMALL DEVICE CONSTRUCTED OF GRAVEL, SANDBAGS, OR FIBER ROLLS, PLACED ACROSS A NATURAL OR
MAN-MADE CHANNEL OR DRAINAGE DITCH. CHECK DAMS REDUCE SCOUR AND CHANNEL EROSION BY REDUCING FLOW
VELOCITIES AND ENCOURAGING SEDIMENT DROPOUT.
2. PLACE CHECK DAMS AT A DISTANCE THAT WILL ALLOW SMALL POOLS TO BE FORMED BEHIND EACH DAM.
3. CHECK DAMS CONSTRUCTED FROM GRAVEL MUST BE 100% PASSING THE 2" SCREEN AND 10% MAXIMUM PASSING THE NO. 4
SIEVE. DAM MATERIAL MAY BE PITRUN OR CRUSHED AGGREGATE.
4. REMOVE SEDIMENT FROM BEHIND THE DAM WHEN IT ACCUMULATES TO ONE-HALF THE ORIGINAL HEIGHT UNLESS ITS
DRAINAGE AREA HAS BEEN STABILIZED.
5. DISTANCES BETWEEN CHECK DAMS ARE AS FOLLOWS:
- FROM 1% TO 3% PLACE CHECK DAMS AT 300 FT. SPACING
- FROM 3% TO 4% PLACE CHECK DAMS AT 200 FT. SPACING
- FROM 4% + PLACE CHECK DAMS AT 100 FT. SPACING
CHECK DAM SPACING MAY BE ADJUSTED ON A
PROJECT-BY-PROJECT BASIS BY THE ENGINEER. DO NOT USE CHECK DAMS ON 1-2% GRADES UNLESS DETERMINED
NECESSARY BY THE ENGINEER.

DESCRIPTION: A FILTER FENCE IS A VERTICAL BARRIER CONSTRUCTED FROM GEOTEXTILE. THE GEOTEXTILE IS TYPICALLY SUPPORTED
BY A WOVEN WIRE FENCE.
CONSTRUCTION: FILTER FENCES SHALL BE INSTALLED PRIOR TO DISTURBING AREAS REQUIRING THE BMP OR AS SLOPE GRADES ARE
ACHIEVED. THE FILTER FENCE SHALL BE BUILT ALONG THE TERRAIN CONTOUR SO THAT WATER IS FILTERED UNIFORMLY ALONG THE
FENCE. INSTALLATION SHALL BE IN ACCORDANCE WITH THE MANUFACTURER'S RECOMMENDATIONS, IN DITCHES OR SWALES, THE FENCE
SHALL CURVE UPSTREAM AT THE ENDS TO PREVENT FLOW FROM BY-PASSING THE FENCE. FILTER FENCES SHALL NOT BE PLACED IN LIVE
STREAMS. THE FENCES SHALL BE POSITIONED TO PREVENT SEDIMENT FROM ENTERING DRAINAGES.
MAINTENANCE AND MONITORING: INSPECT THE FILTER FENCE AT LEAST ONCE EVERY SEVEN CALENDAR DAYS AND WITHIN 24 HOURS
AFTER EACH RUNOFF PRODUCING RAINFALL EVENT. ONE INSPECTION SHALL OCCUR DURING THE FIRST RUNOFF PRODUCING EVENT TO
ASSURE PROPER FUNCTIONING. REPAIR OR REPLACE IF NECESSARY. SEDIMENT MUST BE REMOVED WHEN IT REACHES ONE THIRD THE
HEIGHT OF THE FENCE. REMOVE OR GRADE AND SEED SEDIMENT DEPOSITS BEFORE REMOVING THE FENCE. FILTER FENCES SHALL BE
REMOVED BY OTHERS AFTER FINAL SITE STABILIZATION IS ACHIEVED.

CONSTRUCTION
A. ALIGNMENT: The fence will be built in straight line segments from brace to brace. All turns will require a corner brace which will be installed with the angle of the brace in line with the fence direction.
B. CLEARING: All brush will be cleared to the width necessary to construct the fences. All wires will be free of brush and limbs.
C. LINE POSTS: Spacing for the line posts will ve 16ft. between posts. Steel posts shall be driven until the anchor plate is at least 4" into the ground.
D. Braces:
1. LINE BRACES: Line braces will be placed a minimum of every mile of stretch. Corner or grate braces will as line braces if placed within mile of the last line brace. Line braces will consist of two brace posts and one horizontal post. The brace posts will be set a minimum of 36" in the ground and tamped in layers around the post untiil firm, No. 9 wire brace will be double wire twisted tight. The twist stick shall be secured in place.
2. GATE BRACES: Construct gate braces as described above and shown on the drawing, where indicated on the plans.
Gates will be a minimum of 12 ft. wide with two twisted wire stays at width. Gate sticks will have a diameter of 3"-4". No 9 smooth wire will be used for all bales on brace posts.
3. CORNER BRACES: Corner braces will be placed at all turns in fence, constructed as described above and shown on the drawings.
E. BARRICADE MARKERS: 2 each 3"x12" PVC pipes shall be wraped with red and white reflective tape, at 45 degree angle. Slide the PVC pipe over the wire.
MATERIALS
A. POSTS:
1. Steel Line Post: Standard T post with a steel anchor plate, 5
ft. minimum length.
2. Wooden Brace Post: Pressure treated post with minimuym 6" diameter top x 8 ft.
3. Horizontal or Bracing Post: Minimum 4" diameter treated rail.
B. WIRE
1. Barbed Wire: Galvanized 12.5 gage, strength 90,000 to 105,000 psi.
2. Smooth Wire: No. 9, galvanized (for brace wire and gate loops).
C. STAYS: Stays shall be twisted wire. Wire stays will be 30"-36" long.
D. Staples: Galvanized, 1
" long.
E. GATE CLOSERS: Closeres shall ve "Sure Shut" manufactured by B&B Fabrications
Grass Range, MT (406) 428-2355, or equivalent.
