INFORMATION
STORMWATER POLLUTION PREVENTION PLAN (SWPPP)
TO INCORPORATE ECOLOGY’S REQUIRED BMPS FOR
CONSTRUCTION DEMOLITION, AS OUTLINED IN THE 2024
STORMWATER MANAGEMENT MANUAL FOR WESTERN
WASHINGTON (VOLUME IV, CHAPTER 7, BMP S438).
ABATEMENT CORPORATION AND DEMOLITION COMPANY
TO ADDRESS THE FOLLOWING:
1 POLLUTANT SOURCE CONTROL
IDENTIFY AND PROPERLY DISPOSE OF HAZARDOUS
SUBSTANCES PRIOR TO DEMOLITION (E.G., PCBS,
ASBESTOS, LEAD-BASED PAINT, MERCURY
SWITCHES).
PREVENT EXPOSURE OF HAZARDOUS MATERIALS TO
STORMWATER.
INCLUDE DUST CONTROL MEASURES THAT AVOID
RUNOFF.
2 SITE PROTECTION
COVER ALL DEBRIS PILES AND DUMPSTERS.
PLACE STORM DRAIN COVERS OR SIMILAR
CONTAINMENT DEVICES BEFORE WORK BEGINS EACH
DAY; REMOVE THEM ONLY AFTER SWEEPING AND
CLEANING AT THE END OF EACH DAY.
PROTECT STORMWATER INLETS AND OVERLAND
FLOW PATHS USING BERMS, DIKES, OR OTHER
CONTROLS.
3 DEBRIS AND DUST MANAGEMENT
SWEEP ADJACENT PAVED SURFACES DAILY; COLLECT
AND DISPOSE OF DEBRIS APPROPRIATELY.
USE WATER TRUCKS OR HYDRANTS FOR DUST
SUPPRESSION, ENSURING THAT WATER USED DOES
NOT RESULT IN RUNOFF.
4 PCBS IN BUILDING MATERIALS
FOLLOW ECOLOGY’S 2024 GUIDANCE DOCUMENT:
HOW TO FIND AND ADDRESS PCBS IN BUILDING
MATERIALS.
VISUALLY INSPECT POTENTIAL PCB-CONTAINING
MATERIALS DURING THE PLANNING PHASE AND
ENSURE INTEGRITY IS MAINTAINED UNTIL REMOVAL.
IMPLEMENT BMPS SUCH AS CATCH BASIN INSERTS,
DRY SWEEPING, AND AVOIDANCE OF LEAF BLOWERS
NEAR DEGRADED MATERIALS.
NOTIFY THE LOCAL STORMWATER PROGRAM IF PCBS
ARE KNOWN OR LIKELY TO BE PRESENT.
5 RECOMMENDED BEST PRACTICES
USE SCREENING TO CONTAIN WIND-BLOWN DEBRIS.
SCHEDULE DEMOLITION FOR DRY PERIODS
WHENEVER POSSIBLE.
ADDITIONAL DEMOLITION BMP'S
BMP C105: STABILIZED CONSTRUCTION ENTRANCE / EXIT
PURPOSE
STABILIZED CONSTRUCTION ENTRANCES ARE ESTABLISHED TO REDUCE THE AMOUNT OF SEDIMENT TRANSPORTED ONTO
PAVED ROADS BY VEHICLES OR EQUIPMENT. THIS IS DONE BY CONSTRUCTING A STABILIZED PAD OF QUARRY SPALLS AT
ENTRANCES AND EXITS FOR CONSTRUCTION SITES.
CONDITIONS OF USE
CONSTRUCTION ENTRANCES SHALL BE STABILIZED WHEREVER TRAFFIC WILL BE ENTERING OR LEAVING A CONSTRUCTION
SITE IF PAVED ROADS OR OTHER PAVED AREAS ARE WITHIN 1,000 FEET OF THE SITE. FOR RESIDENTIAL CONSTRUCTION
PROVIDE STABILIZED CONSTRUCTION ENTRANCES FOR EACH RESIDENCE, RATHER THAN ONLY AT THE MAIN SUBDIVISION
ENTRANCE. STABILIZED SURFACES SHALL BE OF SUFFICIENT LENGTH/WIDTH TO PROVIDE VEHICLE ACCESS/PARKING,
BASED ON LOT SIZE/CONFIGURATION. ON LARGE COMMERCIAL, HIGHWAY, AND ROAD PROJECTS, THE DESIGNER SHOULD
INCLUDE ENOUGH EXTRA MATERIALS IN THE CONTRACT TO ALLOW FOR ADDITIONAL STABILIZED ENTRANCES NOT SHOWN IN
THE INITIAL CONSTRUCTION SWPPP. IT IS DIFFICULT TO DETERMINE EXACTLY WHERE ACCESS TO THESE PROJECTS WILL
TAKE PLACE; ADDITIONAL MATERIALS WILL ENABLE THE CONTRACTOR TO INSTALL THEM WHERE NEEDED.
BMP C233: SILT FENCE
PURPOSE
USE OF A SILT FENCE REDUCES THE TRANSPORT OF COARSE SEDIMENT FROM A CONSTRUCTION SITE BY PROVIDING A
TEMPORARY PHYSICAL BARRIER TO SEDIMENT AND REDUCING THE RUNOFF VELOCITIES OF OVERLAND FLOW. SEE FIGURE
II-4.2.12 SILT FENCE (P.369) FOR DETAILS ON SILT FENCE CONSTRUCTION.
CONDITIONS OF USE
SILT FENCE MAY BE USED DOWNSLOPE OF ALL DISTURBED AREAS.
SILT FENCE SHALL PREVENT SOIL CARRIED BY RUNOFF WATER FROM GOING BENEATH, THROUGH, OR OVER THE TOP OF
THE SILT FENCE, BUT SHALL ALLOW THE WATER TO PASS THROUGH THE FENCE.
SILT FENCE IS NOT INTENDED TO TREAT CONCENTRATED FLOWS, NOR IS IT INTENDED TO TREAT SUBSTANTIAL AMOUNTS
OF OVERLAND FLOW. CONVEY ANY CONCENTRATED FLOWS THROUGH THE DRAINAGE SYSTEM TO A SEDIMENT POND.
DO NOT CONSTRUCT SILT FENCES IN STREAMS OR USE IN V-SHAPED DITCHES. SILT FENCES DO NOT PROVIDE AN
ADEQUATE METHOD OF SILT CONTROL FOR ANYTHING DEEPER THAN SHEET OR OVERLAND FLOW.
BMP T5.13: POST-CONSTRUCTION SOIL QUALITY AND
DEPTH
PURPOSE AND DEFINITION
NATURALLY OCCURRING (UNDISTURBED) SOIL AND VEGETATION PROVIDE IMPORTANT STORMWATER FUNCTIONS
INCLUDING: WATER INFILTRATION; NUTRIENT, SEDIMENT, AND POLLUTANT ADSORPTION; SEDIMENT AND POLLUTANT
BIOFILTRATION; WATER INTERFLOW STORAGE AND TRANSMISSION; AND POLLUTANT DECOMPOSITION. THESE FUNCTIONS
ARE LARGELY LOST WHEN DEVELOPMENT STRIPS AWAY NATIVE SOIL AND VEGETATION AND REPLACES IT WITH MINIMAL
TOPSOIL AND SOD. NOT ONLY ARE THESE IMPORTANT STORMWATER FUNCTIONS LOST, BUT SUCH LANDSCAPES
THEMSELVES BECOME POLLUTION GENERATING PERVIOUS SURFACES DUE TO INCREASED USE OF PESTICIDES,
FERTILIZERS AND OTHER LANDSCAPING AND HOUSEHOLD/INDUSTRIAL CHEMICALS, THE CONCENTRATION OF PET WASTES,
AND POLLUTANTS THAT ACCOMPANY ROADSIDE LITTER. ESTABLISHING SOIL QUALITY AND DEPTH REGAINS GREATER
STORMWATER FUNCTIONS IN THE POST DEVELOPMENT LANDSCAPE, PROVIDES INCREASED TREATMENT OF POLLUTANTS
AND SEDIMENTS THAT RESULT FROM DEVELOPMENT AND HABITATION, AND MINIMIZES THE NEED FOR SOME LANDSCAPING
CHEMICALS, THUS REDUCING POLLUTION THROUGH PREVENTION.
APPLICATIONS AND LIMITATIONS
ESTABLISHING A MINIMUM SOIL QUALITY AND DEPTH IS NOT THE SAME AS PRESERVATION OF NATURALLY OCCURRING SOIL
AND VEGETATION. HOWEVER, ESTABLISHING A MINIMUM SOIL QUALITY AND DEPTH WILL PROVIDE IMPROVED ON-SITE
MANAGEMENT OF STORMWATER FLOW AND WATER QUALITY. SOIL ORGANIC MATTER CAN BE ATTAINED THROUGH
NUMEROUS MATERIALS SUCH AS COMPOST, COMPOSTED WOODY MATERIAL, BIOSOLIDS, AND FOREST PRODUCT
RESIDUALS. IT IS IMPORTANT THAT THE MATERIALS USED TO MEET THE SOIL QUALITY AND DEPTH BMP BE APPROPRIATE
AND BENEFICIAL TO THE PLANT COVER TO BE ESTABLISHED. LIKEWISE, IT IS IMPORTANT THAT IMPORTED TOPSOILS
IMPROVE SOIL CONDITIONS AND DO NOT HAVE AN EXCESSIVE PERCENT OF CLAY FINES. THIS BMP CAN BE CONSIDERED
INFEASIBLE ON TILL SOIL SLOPES GREATER THAN 33 PERCENT.
DESIGN GUIDELINES
- SOIL RETENTION. RETAIN, IN AN UNDISTURBED STATE, THE DUFF LAYER AND NATIVE TOPSOIL TO THE MAXIMUM EXTENT
PRACTICABLE. IN ANY AREAS REQUIRING GRADING REMOVE AND STOCKPILE THE DUFF LAYER AND TOPSOIL ON SITE IN A
DESIGNATED, CONTROLLED AREA, NOT ADJACENT TO PUBLIC RESOURCES AND CRITICAL AREAS, TO BE REAPPLIED TO
OTHER PORTIONS OF THE SITE WHERE FEASIBLE.
- SOIL QUALITY. ALL AREAS SUBJECT TO CLEARING AND GRADING THAT HAVE NOT BEEN COVERED BY IMPERVIOUS
SURFACE, INCORPORATED INTO A DRAINAGE FACILITY OR ENGINEERED AS STRUCTURAL FILL OR SLOPE SHALL, AT
PROJECT COMPLETION, DEMONSTRATE THE FOLLOWING:
1. A TOPSOIL LAYER WITH A MINIMUM ORGANIC MATTER CONTENT OF 10% DRY WEIGHT IN PLANTING BEDS, AND 5%
ORGANIC MATTER CONTENT IN TURF AREAS, AND A PH FROM 6.0 TO 8.0 OR MATCHING THE PH OF THE UNDISTURBED SOIL.
THE TOPSOIL LAYER SHALL HAVE A MINIMUM DEPTH OF EIGHT INCHES EXCEPT WHERE TREE ROOTS LIMIT THE DEPTH OF
INCORPORATION OF AMENDMENTS NEEDED TO MEET THE CRITERIA. SUBSOILS BELOW THE TOPSOIL LAYER SHOULD BE
SCARIFIED AT LEAST 4 INCHES WITH SOME INCORPORATION OF THE UPPER MATERIAL TO AVOID STRATIFIED LAYERS,
WHERE FEASIBLE.
2. MULCH PLANTING BEDS WITH 2 INCHES OF ORGANIC MATERIAL.
3. USE COMPOST AND OTHER MATERIALS THAT MEET THESE ORGANIC CONTENT REQUIREMENTS
A. THE ORGANIC CONTENT FOR “PRE-APPROVED” AMENDMENT RATES CAN BE MET ONLY USING COMPOST MEETING THE
COMPOST SPECIFICATION FOR BMP T7.30: BIORETENTION CELLS, SWALES, AND PLANTER BOXES (P.959), WITH THE
EXCEPTION THAT THE COMPOST MAY HAVE UP TO 35% BIOSOLIDS OR MANURE. THE COMPOST MUST ALSO HAVE AN
ORGANIC MATTER CONTENT OF 40% TO 65%, AND A CARBON TO NITROGEN RATIO BELOW 25:1. THE CARBON TO NITROGEN
RATIO MAY BE AS HIGH AS 35:1 FOR PLANTINGS COMPOSED ENTIRELY OF PLANTS NATIVE TO THE PUGET SOUND
LOWLANDS REGION.
B. CALCULATED AMENDMENT RATES MAY BE MET THROUGH USE OF COMPOSTED MATERIAL MEETING (A.) ABOVE; OR
OTHER ORGANIC MATERIALS AMENDED TO MEET THE CARBON TO NITROGEN RATIO REQUIREMENTS, AND NOT EXCEEDING
THE CONTAMINANT LIMITS IDENTIFIED IN TABLE 220-B, TESTING PARAMETERS, IN WAC 173-350-220.
THE RESULTING SOIL SHOULD BE CONDUCIVE TO THE TYPE OF VEGETATION TO BE ESTABLISHED.
L IMPLEMENTATION OPTIONS: THE SOIL QUALITY DESIGN GUIDELINES LISTED ABOVE CAN BE MET BY USING ONE OF THE
METHODS LISTED BELOW:
1. LEAVE UNDISTURBED NATIVE VEGETATION AND SOIL, AND PROTECT FROM COMPACTION DURING CONSTRUCTION.
2. AMEND EXISTING SITE TOPSOIL OR SUBSOIL EITHER AT DEFAULT “PRE-APPROVED” RATES, OR AT CUSTOM CALCULATED
RATES BASED ON TESTS OF THE SOIL AND AMENDMENT.
3. STOCKPILE EXISTING TOPSOIL DURING GRADING, AND REPLACE IT PRIOR TO PLANTING. STOCKPILED TOPSOIL MUST
ALSO BE AMENDED IF NEEDED TO MEET THE ORGANIC MATTER OR DEPTH REQUIREMENTS, EITHER AT A DEFAULT “PRE-
APPROVED” RATE OR AT A CUSTOM CALCULATED RATE.
4. IMPORT TOPSOIL MIX OF SUFFICIENT ORGANIC CONTENT AND DEPTH TO MEET THE REQUIREMENTS.
MORE THAN ONE METHOD MAY BE USED ON DIFFERENT PORTIONS OF THE SAME SITE. SOIL THAT ALREADY MEETS THE
DEPTH AND ORGANIC MATTER QUALITY STANDARDS, AND IS NOT COMPACTED, DOES NOT NEED TO BE AMENDED.
MAINTENANCE
- ESTABLISH SOIL QUALITY AND DEPTH TOWARD THE END OF CONSTRUCTION AND ONCE ESTABLISHED, PROTECT FROM
COMPACTION, SUCH AS FROM LARGE MACHINERY USE, AND FROM EROSION.
- PLANT VEGETATION AND MULCH THE AMENDED SOIL AREA AFTER INSTALLATION.
- LEAVE PLANT DEBRIS OR ITS EQUIVALENT ON THE SOIL SURFACE TO REPLENISH ORGANIC MATTER.
- REDUCE AND ADJUST, WHERE POSSIBLE, THE USE OF IRRIGATION, FERTILIZERS, HERBICIDES AND PESTICIDES, RATHER
THAN CONTINUING TO IMPLEMENT FORMERLY ESTABLISHED PRACTICES.
STORM DRAIN INLET PROTECTION I-40.20-00
SIZE THE BELOW INLET GRATE DEVICE (BIGD) FOR THE STORM WATER STRUCTURE IT WILL SERVICE
THE BIGD SHALL HAVE A BUILT IN HIGH-FLOW RELIEF SYSTEM (OVERFLOW BYPASS).
3 THE RETRIEVAL SYSTEM MUST ALLOW REMOVAL OF THE BIGD WITHOUT SPILLING THE COLLECTED MATERIAL.
4. PERFORM MAINTENANCE IN ACCORDANCE WITH STANDARD SPECIFICATION 8-01.3(15).
BMP C235: WATTLES
PURPOSE
WATTLES ARE TEMPORARY EROSION AND SEDIMENT CONTROL BARRIERS CONSISTING OF STRAW, COMPOST, OR OTHER
MATERIAL THAT IS WRAPPED IN BIODEGRADABLE TUBULAR PLASTIC OR SIMILAR ENCASING MATERIAL. THEY REDUCE THE
VELOCITY AND CAN SPREAD THE FLOW OF RILL AND SHEET RUNOFF, AND CAN CAPTURE AND RETAIN SEDIMENT. WATTLES
ARE TYPICALLY 8 TO 10 INCHES IN DIAMETER AND 25 TO 30 FEET IN LENGTH. WATTLES ARE PLACED IN SHALLOW TRENCHES
AND STAKED ALONG THE CONTOUR OF DISTURBED OR NEWLY CONSTRUCTED SLOPES. SEE FIGURE II-4.2.14 WATTLES (P.
378) FOR TYPICAL CONSTRUCTION DETAILS. WSDOT STANDARD PLAN I-30.30-00 ALSO PROVIDES INFORMATION ON WATTLES
(HTTP://WWW.WSDOT.WA.GOV/DESIGN/STANDARDS/PLANS.HTM#SECTIONI)
CONDITIONS OF USE
USE WATTLES:
- IN DISTURBED AREAS THAT REQUIRE IMMEDIATE EROSION PROTECTION.
- ON EXPOSED SOILS DURING THE PERIOD OF SHORT CONSTRUCTION DELAYS, OR OVER WINTER MONTHS.
- ON SLOPES REQUIRING STABILIZATION UNTIL PERMANENT VEGETATION CAN BE ESTABLISHED.
- THE MATERIAL USED DICTATES THE EFFECTIVENESS PERIOD OF THE WATTLE. GENERALLY, WATTLES ARE TYPICALLY
EFFECTIVE FOR ONE TO TWO SEASONS.
- PREVENT RILLING BENEATH WATTLES BY PROPERLY ENTRENCHING AND ABUTTING WATTLES TOGETHER TO PREVENT
WATER FROM PASSING BETWEEN THEM.
DESIGN CRITERIA
- INSTALL WATTLES PERPENDICULAR TO THE FLOW DIRECTION AND PARALLEL TO THE SLOPE CONTOUR.
- NARROW TRENCHES SHOULD BE DUG ACROSS THE SLOPE ON CONTOUR TO A DEPTH OF 3- TO 5- INCHES ON CLAY SOILS
AND SOILS WITH GRADUAL SLOPES. ON LOOSE SOILS, STEEP SLOPES, AND AREAS WITH HIGH RAINFALL, THE TRENCHES
SHOULD BE DUG TO A DEPTH OF 5- TO 7- INCHES, OR 1/2 TO 2/3 OF THE THICKNESS OF THE WATTLE.
- START BUILDING TRENCHES AND INSTALLING WATTLES FROM THE BASE OF THE SLOPE AND WORK UP. SPREAD
EXCAVATED MATERIAL EVENLY ALONG THE UPHILL SLOPE AND COMPACTED USING HAND TAMPING OR OTHER METHODS.
- CONSTRUCT TRENCHES AT INTERVALS OF 10- TO 25-FEET DEPENDING ON THE STEEPNESS OF THE SLOPE, SOIL TYPE, AND
RAINFALL. THE STEEPER THE SLOPE THE CLOSER TOGETHER THE TRENCHES.
- INSTALL THE WATTLES SNUGLY INTO THE TRENCHES AND ABUT TIGHTLY END TO END. DO NOT OVERLAP THE ENDS.
- INSTALL STAKES AT EACH END OF THE WATTLE, AND AT 4-FOOT CENTERS ALONG ENTIRE LENGTH OF WATTLE.
- IF REQUIRED, INSTALL PILOT HOLES FOR THE STAKES USING A STRAIGHT BAR TO DRIVE HOLES THROUGH THE WATTLE
AND INTO THE SOIL.
- WOODEN STAKES SHOULD BE APPROXIMATELY 3/4 X 3/4 X 24 INCHES MIN. WILLOW CUTTINGS OR 3/8-INCH REBAR CAN
ALSO BE USED FOR STAKES.
- STAKES SHOULD BE DRIVEN THROUGH THE MIDDLE OF THE WATTLE, LEAVING 2 TO 3 INCHES OF THE STAKE PROTRUDING
ABOVE THE WATTLE.
MAINTENANCE STANDARDS
- WATTLES MAY REQUIRE MAINTENANCE TO ENSURE THEY ARE IN CONTACT WITH SOIL AND THOROUGHLY ENTRENCHED,
ESPECIALLY AFTER SIGNIFICANT RAINFALL ON STEEP SANDY SOILS.
BMP C154: CONCRETE WASHOUT AREA
PURPOSE
PREVENT OR REDUCE THE DISCHARGE OF POLLUTANTS TO STORMWATER FROM CONCRETE WASTE BY CONDUCTING
WASHOUT OFF-SITE, OR PERFORMING ON-SITE WASHOUT IN A DESIGNATED AREA TO PREVENT POLLUTANTS FROM
ENTERING SURFACE WATERS OR GROUND WATER.
CONDITIONS OF USE
CONCRETE WASHOUT AREA BEST MANAGEMENT PRACTICES ARE IMPLEMENTED ON CONSTRUCTION PROJECTS WHERE:
- CONCRETE IS USED AS A CONSTRUCTION MATERIAL.
- IT IS NOT POSSIBLE TO DISPOSE OF ALL CONCRETE WASTEWATER AND WASHOUT OFF-SITE (READY MIX PLANT, ETC.).
- CONCRETE TRUCKS, PUMPERS, OR OTHER CONCRETE COATED EQUIPMENT ARE WASHED ON-SITE. NOTE: IF LESS THAN
10 CONCRETE TRUCKS OR PUMPERS NEED TO BE WASHED OUT ON-SITE, THE WASHWATER MAY BE DISPOSED OF IN A
FORMED AREA AWAITING CONCRETE OR AN UPLAND DISPOSAL SITE WHERE IT WILL NOT CONTAMINATE SURFACE OR
GROUND WATER. THE UPLAND DISPOSAL SITE SHALL BE AT LEAST 50 FEET FROM SENSITIVE AREAS SUCH AS STORM
DRAINS, OPEN DITCHES, OR WATER BODIES, INCLUDING WETLANDS.
BMP C123: PLASTIC COVERING
PURPOSE:
PLASTIC COVERING PROVIDES IMMEDIATE, SHORT-TERM EROSION PROTECTION TO SLOPES AND DISTURBED AREAS.
CONDITIONS OF USE:
PLASTIC COVERING MAY BE USED ON DISTURBED AREAS THAT REQUIRE COVER MEASURES FOR LESS THAN 30 DAYS,
EXCEPT AS STATED BELOW.
PLASTIC IS PARTICULARLY USEFUL FOR PROTECTING CUT AND FILL SLOPES AND STOCKPILES. NOTE: THE RELATIVELY
RAPID BREAKDOWN OF MOST POLYETHYLENE SHEETING MAKES IT UNSUITABLE FOR LONG-TERM (GREATER THAN SIX
MONTHS) APPLICATIONS.
- DUE TO RAPID RUNOFF CAUSED BY PLASTIC COVERING, DO NOT USE THIS METHOD UPSLOPE OF AREAS THAT MIGHT BE
ADVERSELY IMPACTED BY CONCENTRATED RUNOFF. SUCH AREAS INCLUDE STEEP AND/OR UNSTABLE SLOPES.
- PLASTIC SHEETING MAY RESULT IN INCREASED RUNOFF VOLUMES AND VELOCITIES, REQUIRING ADDITIONAL ON-SITE
MEASURES TO COUNTERACT THE INCREASES. CREATING A TROUGH WITH WATTLES OR OTHER MATERIAL CAN CONVEY
CLEAN WATER AWAY FROM THESE AREAS.
- TO PREVENT UNDERCUTTING, TRENCH AND BACKFILL ROLLED PLASTIC COVERING PRODUCTS.
- WHILE PLASTIC IS INEXPENSIVE TO PURCHASE, THE ADDED COST OF INSTALLATION, MAINTENANCE, REMOVAL, AND
DISPOSAL MAKE THIS AN EXPENSIVE MATERIAL, UP TO $1.50-2.00 PER SQUARE YARD.
- WHENEVER PLASTIC IS USED TO PROTECT SLOPES INSTALL WATER COLLECTION MEASURES AT THE BASE OF THE SLOPE.
THESE MEASURES INCLUDE PLASTIC-COVERED BERMS, CHANNELS, AND PIPES USED TO COVEY CLEAN RAINWATER AWAY
FROM BARE SOIL AND DISTURBED AREAS. DO NOT MIX CLEAN RUNOFF FROM A PLASTIC COVERED SLOPE WITH DIRTY
RUNOFF FROM A PROJECT.
BMP C130: SURFACE ROUGHENING
Purpose:
Surface roughening aids in the establishment of vegetative cover, reduces runoff velocity, increases infiltration, and provides for sediment
trapping through the provision of a rough soil surface. Horizontal depressions are created by operating a tiller or other suitable equipment
on the contour or by leaving slopes in a roughened condition by not fine grading them. Use this BMP in conjunction with other BMPs such
as seeding, mulching, or sodding.
CONDITIONS OF USE:
- All slopes steeper than 3H:1V and greater than 5 vertical feet require surface roughening to a depth of 2 to 4 inches prior to seeding.
- Areas that will not be stabilized immediately may be roughened to reduce runoff velocity until seeding takes place.
- Slopes with a stable rock face do not require roughening.
- Slopes where mowing is planned should not be excessively roughened.
