1. ALL WOOD MATERIAL SHOULD BE 4-12 INCHES IN DIAMETER.
2. WEIR -LOGS SHOULD BE ORIENTED SUCH THAT THE LOW POINT IS IN THE
CENTER OF THE CHANNEL, AND THE LOGS ARE SURROUNDED BY RIPRAP.
3. WHERE POSSIBLE, FRESHLY CUT WOOD SPECIES CAN BE SELECTED AS "LIVE
LOGS" —SYCAMORE, WILLOW, AND SILKY DOGWOOD ARE A GOOD SPECIES
FOR THIS APPLICATION.

1. THE CONTRACTOR SHALL SUBMIT STONE SIZE GRADATION FOR APPROVAL.
2. STONE SHALL CONFORM NRCS MATERIAL SPECIFICATION #523.
3. ALL STONE SHALL BE DURABLE MATERIAL FREE FROM CRACKS, BLAST FRACTURES, BEDDING, SEAMS AND
OTHER DEFECTS THAT WOULD TEND TO INCREASE ITS DETERIORATION FROM NATURAL CAUSES.
INSPECTIONS FOR CRACKS, FRACTURES, SEAMS AND DEFECTS SHALL BE MADE BY VISUAL EXAMINATION.
4. STONE SHALL BE FREE FROM DEBRIS, SOIL, DUST, MOSS, OR ANY DELETERIOUS SUBSTANCE
WHATSOEVER.
5. STONE SHALL BE ANGULAR, BLOCK -LIKE ( NOT ELONGATED) MATERIAL WITH THE MEDIAN DIMENSIONAL
CHARACTERISTICS ( PERCENTAGE MEASURED BY WEIGHT) OUTLINED BELOW. THESE ARE MEDIAN
DIMENSIONS, WHICH DENOTE THE LENGTH OF THE MIDDLE AXIS OF THE STONE. ALTERNATE AXES OF
EACH STONE SHALL BE WITHIN THE STONE CLASS (I.E. NO SIDE OF ANY STONE SHALL BE SMALLER THAN
DMIN OR LARGER THAN DMAX)
6. LENGTH: WIDTH RATIO OF EACH STONE SHALE BE 2 OR LESS (I.E. NO MORE THAN TWICE AS LONG AS
WIDE) .
7. CARE SHALL BE TAKEN WHEN HANDLING STONE TO ENSURE THE STONE REMAINS EQUALLY MIXED AND
THE BOTTOM OF THE PILE DOES NOT BECOME PROGRESSIVELY SMALLER.
8. THE STONE SHALL CONFORM TO THE SPECIFIED GRADING LIMITS AFTER IT HAS BEEN PLACED. GRADING
TESTS SHALL BE PERFORMED, AS NECESSARY, ACCORDING TO ASTM D 5519, METHOD A, B, OR C, AS
APPLICABLE.
9. THE SUBGRADE SURFACE ON WHICH THE STONE OR FILTER MATERIAL IS TO BE PLACED SHALL BE CUT OR
FILLED AND GRADED TO THE LINES AND GRADES SHOWN ON THE DRAWINGS.
10. THE STONE SHALL BE PLACED BY EQUIPMENT ON THE SURFACE AND TO THE DEPTH SPECIFIED. IT SHALL
BE INSTALLED TO THE FULL COURSE THICKNESS IN ONE OPERATION AND IN SUCH A MANNER AS TO AVOID
SERIOUS DISPLACEMENT OF THE UNDERLYING MATERIAL. THE STONE SHALL BE DELIVERED AND PLACED
IN MANNER THAT ENSURES THE LARGER STONES ARE EQUALLY DISTRIBUTED AND FIRMLY IN CONTACT
WITH THE SMALLER ROCKS AND SPALLS FILLING THE VOIDS BETWEEN THE LARGER STONES. SOME HAND
PLACING WILL BE REQUIRED TO PROVIDE NEAT AND UNIFORM SURFACE.
11. WHERE THE ENGINEER HAS SPECIFIED FILTER, BEDDING, OR GEOTEXTILE BENEATH THE STONE, THE
DESIGNATED MATERIAL SHALL BE PLACED ON THE PREPARED SUBGRADE SURFACE AS SPECIFIED.
COMPACTION OF FILTER OR BEDDING AGGREGATE IS NOT REQUIRED, BUT THE SURFACE OF SUCH
MATERIAL SHALL BE FINISHED REASONABLY SMOOTH AND FREE OF MOUNDS, DIPS, OR WINDROWS.
12. AS DIRECTED ON THE DRAWINGS, INTERSTITIAL SPACE BETWEEN STONE SHOULD BE BACKFILLED WITH
THE CHINKING LAYER TO CREATE A TIGHTLY -PACKED MATRIX OF STONE ARMORING.
13. IN INSTANCES WHERE THE STONE IS NOT HAND -PLACED, STONE SHALL BE DUMPED AND PUSHED AND
TAMPED INTO PLACE WITH HEAVY EQUIPMENT, CREATING A RELATIVELY SMOOTH FINISHED SURFACE.
