NOTES: CONSTRUCTION MATTING BEST
MANAGEMENT PRACTICES
INSTALLATION:
1. MATS SHOULD BE IN GOOD CONDITION TO ENSURE
PROPER INSTALLATION, USE AND REMOVAL. OPERATING
HEAVY EQUIPMENT IN WETLANDS SHALL BE MINIMIZED, AND
SUCH EQUIPMENT OTHER THAN FIXED EQUIPMENT (DRILL
RIGS, FIXED CRANES, ETC.) SHALL NOT BE STORED,
MAINTAINED, FUELED OR REPAIRED IN WETLANDS UNLESS
THE EQUIPMENT IS BROKEN DOWN AND CANNOT BE EASILY
REMOVED.
2. WOODY VEGETATION (TREES, SHRUBS, ETC.) SHALL BE
CUT AT OR ABOVE GROUND LEVEL AND NOT UPROOTED IN
ORDER TO PREVENT DISRUPTION TO THE WETLAND SOIL
STRUCTURE AND TO ALLOW STUMP SPROUTS TO
REVEGETATE THE WORK AREA.
3. WHERE FEASIBLE, PLACE MATS IN A LOCATION THAT
WOULD MINIMIZE THE AMOUNT NEEDED FOR
THE WETLANDS CROSSING.
4. MINIMIZE IMPACTS TO WETLAND AREAS DURING
INSTALLATION, USE, AND REMOVAL.
5. INSTALL ADEQUATE EROSION AND SEDIMENT CONTROLS
AT APPROACHES TO MATS TO PROMOTE A SMOOTH
TRANSITION TO, AND MINIMIZE SEDIMENT TRACKING ONTO,
SWAMP MATS.
6. IN MOST CASES, CONSTRUCTION MATS SHOULD BE
PLACED ALONG THE TRAVEL AREA SO THAT THE
INDIVIDUAL BOARDS ARE RESTING PERPENDICULAR TO THE
DIRECTION OF TRAFFIC. NO GAPS SHOULD EXIST BETWEEN
MATS. PLACE MATS FAR ENOUGH ON EITHER SIDE OF THE
RESOURCE AREA TO REST ON FIRM GROUND.
WETLAND/STREAM CHANNEL CROSSING:
1. AT 'DRY"CROSSINGS WHERE NO FLOW IS PRESENT OR
ANTICIPATED DURING PROJECT CONSTRUCTION, THE MATS
MAY BE PLACED DIRECTLY ONTO THE GROUND IN ORDER
TO PREVENT EXCESSIVE RUTTING, PROVIDED STREAM
BANKS AND BOTTOMS ARE NOT ADVERSELY ALTERED.
2. CONSTRUCTION MATS MAY BE USED AS A TEMPORARY
BRIDGE OVER A STREAM TO ALLOW VEHICLES ACCESS TO
THE WORK SITE. SMALL SECTIONS OF MAT ARE PLACED
WITHIN AND ALONG THE STREAM PARALLEL TO THE FLOW
OF WATER. MATS MAY THEN BE PLACED PERPENDICULAR
TO THE STREAM, RESTING ON TOP OF THE INITIAL
CONSTRUCTION MAT SUPPORTS. IT MAY BE NECESSARY TO
scat hamagcmc.nt Pr. -ti—Manual€ Utikty Mit-
-1. and Adjacent to Wetlands and Wat-b.&-
Interim January 2010_
PLACE ADDITIONAL REINFORCEMENT FOR EXTRA STABILITY
AND TO MINIMIZE THE AMOUNT OF SEDIMENT THAT COULD
FALL BETWEEN THE SPACES OF EACH TIMBER.
3. MATS SHOULD NOT BE PLACED SO THAT THEY
RESTRICT THE NATURAL FLOW OF THE STREAM.
4. MINIMIZE NUMBER OF STREAM/WETLAND CROSSINGS.
WHERE FEASIBLE, LOCATE CROSSING SITE WHERE STREAM
CHANNEL IS NARROW FOR THE SHORTEST POSSIBLE CLEAR
SPAN AND WHERE STREAM BANKS ARE STABLE AND WELL
DEFINED. FOR LARGE WETLAND COMPLEXES, CONSIDER
ACCESSING STRUCTURES FROM OPPOSITE SIDES WHERE
POSSIBLE TO AVOID CROSSING THE ENTIRE WETLAND.
5. MORE THAN ONE LAYER OF MATS MAY BE
NECESSARY IN AREAS WHICH ARE INUNDATED OR HAVE
DEEP ORGANIC WETLAND SOILS.
REMOVAL/RESTORATION:
1. MATTING SHOULD BE REMOVED BY `BACKING" OUT OF
THE SITE, REMOVING MATS ONE AT A TIME. ANY RUTTING
OR SIGNIFICANT INDENTATIONS IDENTIFIED DURING MAT
REMOVAL SHOULD BE REGRADED IMMEDIATELY, TAKING
CARE NOT TO COMPACT SOILS.
2. MATS SHOULD BE CLEANED BEFORE TRANSPORT TO
ANOTHER WETLAND LOCATION TO REMOVE SOIL AND ANY
INVASIVE PLANT SPECIES SEED STOCK OR PLANT
MATERIAL.
3. MATS SHALL BE CLEANED OF SOIL AND ANY INVASIVE
PLANT SPECIES SEED STOCK OR PLANT MATERIAL FROM
BEFORE INSTALLATION.
4. CROSSINGS SHOULD BE INSPECTED FOLLOWING MAT
REMOVAL TO DETERMINE THE LEVEL OF RESTORATION
REQUIRED.
SPECIAL PRECAUTIONS SHOULD BE TAKEN TO PROMPTLY
STABILIZE AREAS OF DISTURBED SOIL LOCATED NEAR
WETLANDS AND STREAMS. MATTED AREAS WITHIN
WETLANDS SHALL BE RESTORED TO THEIR ORIGINAL
CONDITION AND ELEVATION. THIS MAY INVOLVE NATURAL
REVEGETATION FROM EXISTING ROOT AND SEED STOCK OF
NATIVE PLANT SPECIES. CONDITIONS MAY WARRANT
PLANTING AND THE BROADCAST OF A WETLAND SEED MIX
OVER THE MATTED AREA TO SUPPLEMENT THE EXISTING
SEED AND ROOTSTOCK. SEED MIXES AND VEGETATION
SHALL CONTAIN ONLY PLANT SPECIES NATIVE TO NORTH
