The Broken Saddle Culvert Replacement project is located in Kernersville, NC and is bound by Broken Saddle Lane and Marylebone Drive as shown in Figure 1. The existing watershed
encompasses 104 acres of high- to low -density residential areas with some commercial areas. The proposed project extends approximately 250 linear feet along the unnamed tributary
to Reedy Fork located under Broken Saddle Lane and Marylebone Drive. WK Dickson personnel conducted an on -site field assessment of the Waters of the US on July 9th, 2019.

4f. List the total estimated acreage of all existing wetlands on the property:
4g. List the total estimated linear feet of all existing streams on the property:

4h. Explain the purpose of the proposed project:*
The proposed project purpose is to replace the existing undersized 60-foot long 24" corrugated metal pipe (CMP) lined reinforced concrete pipe (RCP) culvert under Broken Saddle
Lane to provide adequate flow and to stabilize the channel. The existing culvert is undersized and causes significant ponding that is adversely effecting the residents located upstream
Historic observations and reports of flooding at private properties in the vicinity of the Broken Saddle Lane culvert has been recorded. During a field visit by WK Dickson personnel, a
citizen claimed the water rose 70-inches at 716 Corjon Road during a large summer event. High water marks on the structure validated this claim.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The existing Broken Saddle Lane culvert will be replaced with a 60-foot long 48" RCP. The new culvert will be placed in the horizontal footprint of the existing culvert. The proposed
design a custom headwall and endwall. A plunge pool is proposed on the downstream end of the endwall to mimic the existing stream bed elevations and prevent erosion and scouring
downstream of the enlarged culvert. Boulder toe walls are incorporated into the banks of the stream to protect the adjacent sewer and minimize erosion to the stream banks.
The proposed project includes improvements upstream and downstream of the Marylebone Drive culvert. This culvert is adequately sized for the Town's design storm, however the
downstream channel bed has experienced scouring and a large pool has formed, separating the channel bed from the culvert invert. The proposed improvements include extending the
culvert with 60" CMP and adding a 22.5-degree bend followed by a custom endwall. The culvert extension is intended to protect adjacent utilities and private structures from being
damaged due to bank erosion. A buried riffle grade control is proposed downstream of the endwall to provide stability to the channel bed.
4j. Please upload project drawings for the proposed project.

la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
During the planning and design phase of the project, efforts were made to avoid impacts to the greatest extent possible. Certain unavoidable impacts
are necessary to fulfill the purpose and need of the project. Stream impacts have been reduced by limiting the size of the project area and with
construction techniques that include headwalls and embedding the culverts. Installations of grade control structures below ORWMs are limited in
placement and size to the minimum necessary to ensure channel stability. Also, to reduce permanent impacts to jurisdictional waters, epsting channel
substrates will be restored following construction.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
To minimize impacts to surface water resources during the project construction and maintenance, an erosion and sedimentation control plan will be
included in the project's design plans. Soft stabilization practices including installation of grade control structures, coir matting installation, and seeding
will be used throughout the project. All erosion control measures will be placed in accordance with the Erosion Control Regulations. Local stormvater
and erosion control regulations will be followed on the project site. Local stormwater and erosion control regulations will be followed on the project site.
The stabilized stream banks will be planted with native vegetation. Ongoing on -site construction inspection will ensure that construction contractors
are following all DEQ-approved plans.

CONSTRUCTION. CHANNEL BANKS SHALL BE SEEDED DAILY UPON COMPLETION OF FINAL GRADING.
8. ALL SEDIMENT AND EROSION CONTROLS ARE TO BE INSPECTED AT LEAST ONCE EVERY SEVEN CALENDAR DAYS AND AFTER ANY STORM EVENT OF GREATER THAN 0.5 INCHES OF PRECIPITATION
DURING ANY 24-HOUR PERIOD. MAINTENANCE OF SEDIMENT TRAPPING STRUCTURES SHALL BE PERFORMED AS NECESSARY PER THESE INSPECTIONS. SILT FENCING AND DIVERSION DITCHES
SHALL BE INSTALLED AS SHOWN ON EROSION CONTROL SHEETS.
9. STABILIZATION MEASURES SHALL BE INITIATED AT THE END OF EACH DAY IN PORTIONS OF THE SITE WHERE CONSTRUCTION ACTIVITIES HAVE TEMPORARILY OR PERMANENTLY CEASED EXCEPT
WHERE CONSTRUCTION ACTIVITIES SHALL BE REINITIATED WITHIN 7 CALENDAR DAYS.
10. ALL EROSION CONTROL DEVICES SHALL BE PROPERLY MAINTAINED DURING ALL PHASES OF CONSTRUCTION UNTIL THE COMPLETION OF ALL CONSTRUCTION ACTIVITIES AND ALL DISTURBED
AREAS HAVE BEEN STABILIZED. ADDITIONAL CONTROL DEVICES MAY BE REQUIRED DURING CONSTRUCTION IN ORDER TO CONTROL EROSION AND/OR OFFSITE SEDIMENTATION. CONTRACTOR
SHALL REMOVE ALL TEMPORARY CONTROL DEVICES ONCE CONSTRUCTION IS COMPLETE AND THE SITE IS STABILIZED. A MAXIMUM OF 51 LINEAR FEET OF STREAM MAY BE DISTURBED AT ANY
ONE TIME.
11. SILT FENCING TO BE INSTALLED AROUND INDICATED SPOILS AREAS TO PREVENT LOSS OF SEDIMENT.
12. ALL NECESSARY MEASURES MUST BETAKEN TO PREVENT OIL, TAR, TRASH, AND OTHER POLLUTANTS FROM ENTERING THE ADJACENT OFFSITE AREAS.
13. CONSTRUCTION ACTIVITIES MUST AVOID TO THE GREATEST EXTENT PRACTICABLE, ENCROACHMENT INTO ANY WETLAND/STREAM AREAS NOT DESIGNATED AS IMPACT AREAS.
14. ACTIVITIES MUST AVOID DISTURBANCE OF WOODY RIPARIAN VEGETATION WITHIN THE PROJECT AREA TO THE GREATEST EXTENT PRACTICABLE. REMOVAL OF VEGETATION MUST BE LIMITED TO
ONLY THAT NECESSARY FOR CONSTRUCTION OF THE CHANNEL.
15. NO ON -SITE BURIAL OF VEGETATION OR CONSTRUCTION DEBRIS WILL BE PERMITTED.
16. ANY GRADING BEYOND THE CONSTRUCTION LIMITS SHOWN ON THE PLAN IS A VIOLATION OF THE NORTH CAROLINA EROSION CONTROL ORDINANCE, AND IS SUBJECT TO A FINE.
17. PLEASE REFERENCE PLAN SHEET DETAILS AND NCDENR STANDARDS FOR CONSTRUCTION OF EROSION CONTROL MEASURES.
18. THERE WILL BE PUMP AROUND USED ANYWHERE A CHANNEL IS DISTURBED.
19. PROVIDE SELF -INSPECTION PARAGRAPH WITH LOCATION OF WEBSITE FOR ACCESS TO INSPECTION FORM. A COPY OF THE APPROVED PLAN, PLAN APPROVAL, NPDES PERMIT AND COPIES OF
PAST 30 DAYS SELF -INSPECTION REPORTS ARE TO BE KEPT ON SITE AT ALL TIMES.

MAINTENANCE NOTES:
CONTINUE TO CARE FOR THE SITE UNTIL THE NEW OWNER TAKES POSSESSION. TAKE THE
FOLLOWING STEPS AFTER ALL MATERIALS AND EQUIPMENT HAVE BEEN REMOVED FROM THE
SI TE:
• REMOVE TREE PROTECTION ZONE FENCES.
• PRUNE ANY DAMAGED TREES. IN SPITE OF PRECAUTIONS, SOME DAMAGE TO PROTECTED
TREES MAY OCCUR. IN SUCH CASES, REPAIR ANY DAMAGE TO THE CROWN, TRUNK, OR
ROOT SYSTEM IMMEDIATELY. EXISTING
• REPAIR ROOTS BY CUTTING OFF THE DAMAGED AREAS AND PAINTING THEM WITH TREE
PAINT. SPREAD PEAT MOSS OR MOIST TOPSOIL OVER EXPOSED ROOTS.
• REPAIR DAMAGE TO BARK BY TRIMMING AROUND THE DAMAGED AREA AS SHOWN IN
FIGURE 1 BELOW, TAPER THE CUT TO PROVIDE DRAINAGE, AND PAINT WITH TREE PAINT.
• CUT OFF ALL DAMAGED TREE LIMBS ABOVE THE TREE COLLAR AT THE TRUNK OR MAIN
BRANCH. USE THREE SEPARATE CUTS AS SHOWN IN FIGURE 1 BELOW TO AVOID PEELING
BARK FROM HEALTHY AREAS OF THE TREE.
• CONTINUE MAINTENANCE CARE. PAY SPECIAL ATTENTION TO ANY STRESSED, DISEASED,
OR INSECT -INFESTED TREES, REDUCE TREE STRESS CAUSED BY UNINTENDED
CONSTRUCTION DAMAGE BY OPTIMIZING PLANT CARE WITH WATER, MULCH, AND
FERTILIZER WHERE APPROPRIATE. CONSULT YOUR TREE EXPERT IF NEEDED. DRIP UNE-
• INFORM THE PROPERTY OWNER ABOUT THE MEASURES EMPLOYED DURING CONSTRUCTION,
WHY THOSE MEASURES WERE TAKEN, AND HOW THE EFFORT CAN BE CONTINUED.

RIP RAP (6.15)
CONSTRUCTION SPECIFICATIONS
SUBGRADE PREPARATION - PREPARE THE SUBGRADE FOR RIP RAP AND FILTER TO THE REQUIRED LINES AND GRADES SHOWN ON THE
PLANS. COMPACT ANY FILL REQUIRED IN THE SUBGRADE TO A DENSITY APPROXIMATING THAT OF THE SURROUNDING UNDISTURBED
MATERIAL OR OVERFILL DEPRESSIONS WITH RIP RAP. REMOVE BRUSH, TREES, STUMPS AND OTHER OBJECTIONAL MATERIAL. CUT THE
SUBGRADE SUFFICIENTLY DEEP THAT THE FINISHED GRADE OF THE RIP RAP WILL BE AT THE ELEVATION OF THE SURROUNDING AREA.
CHANNELS SHOULD BE EXCAVATED SUFFICIENTLY TO ALLOW PLACEMENT OF THE RIP RAP IN A MANNER SUCH THAT THE FINISHED
INSIDE DIMENSIONS AND GRADE OF THE RIP RAP MEET DESIGN SPECIFICATIONS.
SAND AND GRAVEL FILTER BLANKET - PLACE THE FILTER BLANKET IMMEDIATELY AFTER THE GROUND FOUNDATION IS PREPARED. FOR
GRAVEL, SPREAD FILTER STONE IN A UNIFORM LAYER TO THE SPECIFIED DEPTH. WHERE MORE THAN ONE LAYER OF FILTER MATERIAL IS
USED, SPREAD THE LAYERS WITH MINIMAL MIXING.
SYNTHETIC FILTER FABRIC - PLACE THE CLOTH FILTER DIRECTLY ON THE PREPARED FOUNDATION. OVERLAP THE EDGES BY AT LEAST
12 INCHES, AND SPACE ANCHOR PINS EVERY 3 FT ALONG THE OVERLAP. BURY THE UPSTREAM END OF THE CLOTH A MINIMUM OF 12
INCHES BELOW GROUND AND WHERE NECESSARY, BURY THE LOWER END OF THE CLOTH OR OVERLAP WITH THE NEXT SECTION AS
REQUIRED. TAKE CARE NOT TO DAMAGE THE CLOTH WHEN PLACING RIP RAP. IF DAMAGE OCCURS REMOVE THE RIP RAP AND REPAIR
THE SHEET BY ADDING ANOTHER LAYER OF FILTER MATERIAL WITH A MINIMUM OVERLAP OF 12 INCHES AROUND THE DAMAGED AREA. IF
EXTENSIVE DAMAGE IS SUSPECTED, REMOVE AND REPLACE THE ENTIRE SHEET.
WHERE LARGE STONES ARE USED OR MACHINE PLACEMENT IS DIFFICULT, A 4-LNCH LAYER OF FINE GRAVEL OR SAND MAY BE NEEDED TO
PROTECT THE FILTER CLOTH.
STONE PLACEMENT - PLACEMENT OF RIP RAP SHOULD FOLLOW IMMEDIATELY AFTER PLACEMENT OF THE FILTER. PLACE RIP RAP SO THAT
IT FORMS A DENSE, WELL -GRADED MASS OF STONE WITH A MINIMUM OF VOIDS. THE DESIRED DISTRIBUTION OF STONES THROUGHOUT THE
MASS MAYBE OBTAINED BY SELECTIVE LOADING AT THE QUARRY AND CONTROLLED DUMPING DURING FINAL PLACEMENT. PLACE RIP RAP
TO ITS FULL THICKNESS IN ONE OPERATION. DO NOT PLACE RIP RAP BY DUMPING THROUGH CHUTES OR OTHER METHODS THAT CAUSE
SEGREGATION OF STONE SIZES. TAKE CARE NOT TO DISLODGE THE UNDERLYING BASE OR FILTER WHEN PLACING THE STONES.
THE FINISHED SLOPE SHOULD BE FREE OF POCKETS OF SMALL STONE OR CLUSTERS OF LARGE STONES. HAND PLACING MAY BE
NECESSARY TO ACHIEVE THE PROPER DISTRIBUTION OF STONE SIZES TO PRODUCE A RELATIVELY SMOOTH, UNIFORM SURFACE. THE
FINISHED GRADE OF THE RIP RAP SHOULD BLEND WITH THE SURROUNDING AREA. NO OVERFALL OR PROTRUSION OF RIP RAP SHOULD BE
APPARENT.
IT, I1IzIINzI\Ry3
INSPECT CHANNELS AT REGULAR INTERVALS AS WELL AS AFTER MAJOR RAINS, AND MAKE REPAIRS PROMPTLY. GIVE SPECIAL ATTENTION
TO THE OUTLET AND INLET SECTIONS AND OTHER POINTS WHERE CONCENTRATED FLOW ENTERS. CAREFULLY CHECK STABILITY AT ROAD
CROSSINGS AND LOOK FOR INDICATIONS OF PIPING, SCOUR HOLES, OR BANK FAILURES. MAKE REPAIRS IMMEDIATELY. MAINTAIN ALL
VEGETATION ADJACENT TO THE CHANNEL IN A HEALTHY, VIGOROUS CONDITION TO PROTECT THE AREA FROM EROSION AND SCOUR DURING
OUT -OF -BANK FLOW. CONTROL OF WEED AND BRUSH GROWTH MAY BE NEEDED IN SOME LOCATIONS.
LAND GRADING (6.02)
CONSTRUCTION SPECIFICATIONS
1. CONSTRUCT AND MAINTAIN ALL EROSION AND SEDIMENTATION CONTROL PRACTICES AND MEASURES IN ACCORDANCE WITH THE
APPROVED SEDIMENTATION CONTROL PLAN AND CONSTRUCTION SCHEDULE.
2. REMOVE GOOD TOPSOIL FROM AREAS TO BE GRADED AND FILLED, AND PRESERVE IT FOR USE IN FINISHING THE GRADING OF ALL
CRITICAL AREAS.
3. SCARIFY AREAS TO BE TOPSOILED TO A MINIMUM DEPTH OF 2 INCHES BEFORE PLACING TOPSOIL.
4. CLEAR AND GRUB AREAS TO BE FILLED TO REMOVE TREES, VEGETATION, ROOTS, OR OTHER OBJECTIONABLE MATERIAL THAT WOULD
AFFECT THE PLANNED STABILITY OF THE FILL.
5. ENSURE THAT FILL MATERIAL IS FREE OF BRUSH, RUBBISH, ROCKS, LOGS, STUMPS, BUILDING DEBRIS, AND OTHER MATERIALS
INAPPROPRIATE FOR CONSTRUCTING STABLE FILLS.
6. PLACE ALL FILL IN LAYERS NOT TO EXCEED 9 INCHES IN THICKNESS,AND COMPACT THE LAYERS AS REQUIRED TO REDUCE EROSION,
SLIPPAGE, SETTLEMENT, OR OTHER RELATED PROBLEMS.
7. DO NOT INCORPORATE FROZEN MATERIAL OR SOFT OR HIGHLY COMPRESSIBLE MATERIALS INTO FILL SLOPES.
8. DO NOT PLACE FILL ON A FROZEN FOUNDATION, DUE TO POSSIBLE SUBSIDENCE AND SLIPPAGE.
9. KEEP DIVERSIONS AND OTHER WATER CONVEYANCE MEASURES FREE OF SEDIMENT DURING ALL PHASES OF DEVELOPMENT.
10. HANDLE SEEPS OR SPRINGS ENCOUNTERED DURING CONSTRUCTION IN ACCORDANCE WITH APPROVED METHODS.
11. PERMANENTLY STABILIZE ALL GRADED AREAS IMMEDIATELY AFTER FINAL GRADING IS COMPLETED ON EACH AREA IN THE GRADING
PLAN PER NPDES SOIL STABILIZATION TIME FRAMES.
12. SHOW TOPSOIL STOCKPILES, BORROW AREAS, AND SPOIL AREAS ON THE PLANS, AND MAKE SURE THEY ARE ADEQUATELY PROTECTED
FROM EROSION. INCLUDE FINAL STABILIZATION OF THESE AREAS IN THE PLAN.
MAINTENANCE
PERIODICALLY CHECK ALL GRADED AREAS AND THE SUPPORTING EROSION AND SEDIMENTATION CONTROL PRACTICES, ESPECIALLY AFTER
HEAVY RAINFALLS. PROMPTLY REMOVE ALL SEDIMENT FROM DIVERSION AND OTHER WATER -DISPOSAL PRACTICES. IF WASHOUTS OR
BREAKS OCCUR, REPAIR THEM IMMEDIATELY. PROMPT MAINTENANCE OF SMALL ERODED AREAS BEFORE THEY BECOME SIGNIFICANT GULLIES
IS AN ESSENTIAL PART OF AN EFFECTIVE EROSION AND SEDIMENTATION CONTROL PLAN.
GRASS -LINED CHANNELS (6.30)
CONSTRUCTION SPECIFICATIONS
1. REMOVE ALL TREES, BRUSH,STUMPS, AND OTHER OBJECTIONABLE MATERIAL FROM THE FOUNDATION AREA AND DISPOSE OF
PROPERLY.
2. EXCAVATE THE CHANNEL AND SHAPE IT TO NEAT LINES AND DIMENSIONS SHOWN ON THE PLANS PLUS A 0.2-FT OVERCUT AROUND
THE CHANNEL PERIMETER TO ALLOW FOR BULKING DURING SEEDBED PREPARATIONS AND SOD BUILDUP.
3. REMOVE AND PROPERLY DISPOSE OF ALL EXCESS SOIL SO THAT SURFACE WATER MAY ENTER THE CHANNEL FREELY.
4. THE PROCEDURE USED TO ESTABLISH GRASS IN THE CHANNEL WILL DEPEND UPON THE SEVERITY OF THE CONDITIONS AND SELECTION
OF SPECIES. PROTECT THE CHANNEL WITH MULCH OR A TEMPORARY LINER SUFFICIENT TO WITHSTAND ANTICIPATED VELOCITIES
DURING THE ESTABLISHMENT PERIOD.
MAINTENANCE
DURING THE ESTABLISHMENT PERIOD, CHECK GRASS -LINED CHANNELS AFTER EVERY RAINFALL. AFTER GRASS IS ESTABLISHED,
PERIODICALLY CHECK THE CHANNEL; CHECK IT AFTER EVERY HEAVY RAINFALL EVENT. IMMEDIATELY MAKE REPAIRS. IT IS PARTICULARLY
IMPORTANT TO CHECK THE CHANNEL OUTLET AND ALL ROAD CROSSINGS FOR BANK STABILITY AND EVIDENCE OF PIPING OR SCOUR HOLES.
REMOVE ALL SIGNIFICANT SEDIMENT ACCUMULATIONS TO MAINTAIN THE DESIGNED CARRYING CAPACITY. KEEP THE GRASS IN A HEALTHY,
VIGOROUS CONDITION AT ALL TIMES, SINCE IT IS THE PRIMARY EROSION PROTECTION FOR THE CHANNEL.

CONSULT CONSERVATION ENGINEER OR SOIL CONSERVATION SERVICE FOR ADDITIONAL INFORMATION CONCERNING OTHER ALTERNATIVES FOR
VEGETATION OF DENUDED. AREAS. THE ABOVE VEGETATION RATES ARE THOSE WHICH DO WELL UNDER LOCAL CONDITIONS: OTHER SEEDING
RATE COMBINATIONS ARE POSSIBLE.
***TEMPORARY - RESEED ACCORDING TO OPTIMUM SEASON FOR DESIRED PERMANENT VEGETATION. DO NOT ALLOW TEMPORARY COVER TO
GROW OVER 12 INCHES IN HEIGHT BEFORE MOWING, OTHERWISE, FESCUE MAY BE SHADED OUT.
SEEDING SPECIFICATIONS
1. AFTER ROUGH GRADING IS COMPLETED, TILL SOIL IN AREAS TO BE SEEDED AND PLANTED TO A DEPTH OF SIX INCHES.
2. APPLY AGRICULTURAL LIME, FERTILIZER, AND SUPERPHOSPHATE TO DISTURBED AREAS TO BE VEGETATED.
2.1. 135 LBS LIMESTONE/1000 SQ FT (3 TONS/ACRE) OR BASED ON SOIL TEST
2.2. 35 LBS 10-10-10 FERTILIZER/1000 SQ FT (1500 LBS/ACRE)
2.3. 40 LBS 50% SUPERPHOSPHATE/1000 SQ FT (1750 LBS/ACRE)
3. DISK NUTRIENTS INTO SOIL TO A DEPTH OF SIX INCHES UNTIL SURFACE IS UNIFORM AND FREE OF LARGE DIRT CLODS.
4. SEEDING PERMANENT GRASS.
4.1. SEE ABOVE TABLE.
5. MULCH SEEDED AREA WITH SMALL GRAIN STRAW AT 90 LBS/1000 SQ FT (2 TONS/ACRE). SPREAD UNIFORMLY. APPROXIMATELY 1/2
OF GROUND SURFACE SHOULD BE VISIBLE TO AVOID BLOCKING SUNLIGHT TO SEEDLINGS. ON AREAS WHERE THE GROUND SURFACE
EQUALS OR EXCEEDS A 3:1 SLOPE, AND IN THE INVERTS OF ALL DRAINAGE SWALES, TACK MULCH WITH ASPHALT EMULSION AT A
RATE OF 450 GALLONS EMULSION PER ACRE OF STRAW.
6. MULCH AROUND SHRUBBERY AND TREES WITH PINE STRAW TO DEPTH OF 3 INCHES.
7. TEMPORARY COVER
7.1. 1.0 LBS BROWN TOP MLLLET/1000 SQ FT MAY THROUGH AUGUST 25. -OR- 1.0 LBS ANNUAL RYEGRASS/1000 SQ FT AUGUST 25
THROUGH APRIL.
8. REFER TO SHEET ## FOR FURTHER DETAIL ON THE TEMPORARY AND PERMANENT VEGETATION SEEDBED PREPARATION.
TOPSOILING (6.04)
CONSTRUCTION SPECIFICATIONS
MATERIALS
1. DETERMINE WHETHER THE QUALITY AND QUANTITY OF AVAILABLE TOPSOIL JUSTIFIES SELECTIVE HANDLING. QUALITY TOPSOIL HAS THE
FOLLOWING CHARACTERISTICS:
1.1. TEXTURE - LOAM, SANDY LOAM, AND SLIT LOAM ARE BEST; SANDY CLAY LOAM, SILTY CLAY LOAM, CLAY LOAM, AND LOAMY
SAND ARE FAIR. DO NOT USE HEAVY CLAY AND ORGANIC SOILS SUCH AS PEAT OR MUCK AS TOPSOIL.
1.2. ORGANIC MATTER CONTENT - (SOMETIMES REFERRED TO AS "HUMIC MATTER") SHOULD BE GREATER THAN 1.5% BY WEIGHT.
1.3. ACIDITY - PH SHOULD BE GREATER THAN 3.6 BEFORE LIMING, AND LIMING IS REQUIRED IF IT IS LESS THAN 6.0.
1.4. SOLUBLE SALTS - SHOULD BE LESS THAN 500 PPM.
1.5. SODIUM - SODIUM ADSORPTION RATIO SHOULD BE LESS THAN 12.
THE DEPTH OF MATERIAL MEETING THE ABOVE QUALIFICATIONS SHOULD BE AT LEAST 2 INCHES. SOIL FACTORS SUCH AS ROCK
FRAGMENTS, SLOPE, DEPTH TO WATER TABLE, AND LAYER THICKNESS AFFECT THE EASE OF EXCAVATION AND SPREADING OF TOPSOIL.
GENERALLY, THE UPPER PART OF THE SOIL, WHICH IS RICHEST IN ORGANIC MATTER, IS MOST DESIRABLE; HOWEVER, MATERIAL EXCAVATED
FROM DEEPER LAYERS MAY BE WORTH STORING IF IT MEETS THE OTHER CRITERIA LISTED ABOVE.
ORGANIC SOILS SUCH AS MUCKS AND PEATS DO NOT MAKE GOOD TOPSOIL. THEY CAN BE IDENTIFIED BY THEIR EXTREMELY LIGHT WEIGHT
WHEN DRY.
STRIPPING
1. STRIP TOPSOIL ONLY FROM THOSE AREAS THAT WILL BE DISTURBED BY EXCAVATION, FILLING, ROAD BUILDING, OR COMPACTION BY
EQUIPMENT. A 4 TO 6-INCH STRIPPING DEPTH IS COMMON, BUT DEPTH VARIES DEPENDING ON THE SITE. DETERMINE DEPTH OF
STRIPPING BY TAKING SOIL CORES AT SEVERAL LOCATIONS WITHIN EACH AREA TO BE STRIPPED. TOPSOIL DEPTH GENERALLY VARIES
ALONG A GRADIENT FROM HILLTOP TO TOE OF THE SLOPE. PUT SEDIMENT BASINS, DIVERSIONS, AND OTHER CONTROLS INTO PLACE
BEFORE STRIPPING.
STOCKPILING
1. SELECT STOCKPILE LOCATION TO AVOID SLOPES AND NATURAL DRAINAGEWAYS, AVOIDING TRAFFIC ROUTES. ON LARGE SITES,
RESPREADING IS EASIER AND MORE ECONOMICAL WHEN TOPSOIL IS STOCKPILED IN SMALL PILES LOCATED NEAR AREAS WHERE THEY
WILL BE USED. ALL STOCKPILE AREAS USED SHALL BE STABILIZED WITH SILT FENCE AND SEEDED PER THE LATEST NPDES RULES.
2. SEDIMENT BARRIERS - USE SEDIMENT FENCES OR OTHER BARRIERS WHERE NECESSARY TO RETAIN SEDIMENT.
3. TEMPORARY SEEDING - PROTECT TOPSOIL STOCKPILES BY TEMPORARILY SEEDING PER THE LATEST NPDES RULES.
4. PERMANENT VEGETATION - IF STOCKPILES WILL NOT BE USED WITHIN 12 MONTHS THEY MUST BE STABILIZED WITH PERMANENT
VEGETATION TO CONTROL EROSION AND WEED GROWTH.
SITE PREPARATION
1. BEFORE SPREADING TOPSOIL, ESTABLISH EROSION AND SEDIMENTATION CONTROL PRACTICES SUCH AS DIVERSIONS, BERMS, DIKES,
WATERWAYS, AND SEDIMENT BASINS.
2. GRADING - MAINTAIN GRADES ON THE AREAS TO BE TOPSOILED ACCORDING TO THE APPROVED PLAN AND DO NOT ALTER THEM BY
ADDING TOPSOIL.
3. LIMING OF SUBSOIL - WHERE THE PH OF THE EXISTING SUBSOIL IS 6.0 OR LESS, OR THE SOIL IS COMPOSED OF HEAVY CLAYS,
INCORPORATE AGRICULTURAL LIMESTONE IN AMOUNTS RECOMMENDED BY SOIL TESTS OR SPECIFIED FOR THE SEEDING MIXTURE TO BE
USED. INCORPORATE LIME TO A DEPTH OF AT LEAST 2 INCHES BY DISKING.
4. ROUGHENING - IMMEDIATELY PRIOR TO SPREADING THE TOPSOIL. LOOSEN THE SUBGRADE BY DISKING OR SCARIFYING TO A DEPTH OF
AT LEAST 4 INCHES, TO ENSURE BONDING OF THE TOPSOIL AND SUBSOIL. IF NO AMENDMENTS HAVE BEEN INCORPORATED, LOOSEN
THE SOIL TO A DEPTH OF AT LEAST 6 INCHES BEFORE SPREADING TOPSOIL.
SPREADING TOPSOIL
1. DO NOT SPREAD TOPSOIL WHILE IT IS FROZEN OR MUDDY OR WHEN SUBGRADE IS WET OR FROZEN. CORRECT ANY IRREGULARITIES IN
THE SURFACE THAT RESULT FROM TOPSOILING OR OTHER OPERATIONS TO PREVENT THE FORMATION OF DEPRESSIONS OR WATER
POCKETS.
2. COMPACT THE TOPSOIL ENOUGH TO ENSURE GOOD CONTACT WITH THE UNDERLYING SOIL, BUT AVOID EXCESSIVE COMPACTION, AS IT
INCREASES RUNOFF AND INHIBITS SEED GERMINATION. LIGHT PACKING WITH A ROLLER IS RECOMMENDED WHERE HIGH -MAINTENANCE
TURF IS TO BE ESTABLISHED.
3. ON SLOPES AND AREAS THAT WILL NOT BE MOWED, THE SURFACE MAY BE LEFT ROUGH AFTER SPREADING TOPSOIL. A DISK MAY BE
USED TO PROMOTE BONDING AT THE INTERFACE BETWEEN TOPSOIL AND SUBSOIL.
4. AFTER TOPSOIL APPLICATION, FOLLOW PROCEDURE FOR SEEDBED PREPARATION, TAKING CARE TO AVOID EXCESSIVE MIXING OF
TOPSOIL INTO THE SUBSOIL.
EROSION CONTROL MATTING:
SEE DETAIL 4/11 FOR CONSTRUCTION SPECIFICATIONS.
MAINTENANCE
1. INSPECT ROLLED EROSION CONTROL MATTING AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (1/2 INCH OR GREATER) RAIN FALL
EVENT REPAIR IMMEDIATELY.
2. GOOD CONTACT WITH THE GROUND MUST BE MAINTAINED, AND EROSION MUST NOT OCCUR BENEATH THE MATTING.
3. ANY AREAS OF THE MATTING THAT ARE DAMAGED OR NOT IN CLOSE CONTACT WITH THE GROUND SHALL BE REPAIRED AND STAPLED.
4. IF EROSION OCCURS DUE TO POORLY CONTROLLED DRAINAGE, THE PROBLEM SHALL BE FIXED AND THE ERODED AREA PROTECTED.
5. MONITOR AND REPAIR THE MATTING AS NECESSARY UNTIL GROUND COVER IS ESTABLISHED.
