1. EROSION MATTING WILL BE USED ON SLOPES STEEPER THAN 3H:1V OR AS SHOWN ON THE PLANS.
2. PREPARE SOIL BEFORE INSTALLING MATTING, INCLUDING ANY NECESSARY APPLICATION OF LIME, FERTILIZER, AND SEED. SOIL
SURFACE SHALL BE GRADED SMOOTH WITHOUT ROOTS, STONES OR OTHER PROTUSIONS THAT WILL PREVENT THE MATTING FROM
BEING APPLIED IN FULL CONTACT WITH THE SOIL SURFACE.
3. BEGIN AT THE TOP OF THE SLOPE BY ANCHORING THE MATTING IN A 6" DEEP X 6" WIDE TRENCH WITH APPROXIMATELY 12" OF
MATTING EXTENDED BEYOND THE UP-SLOPE PORTION OF THE TRENCH. ANCHOR THE MATTING WITH A ROW OF STAPLES/STAKES
APPROXIMATELY 12" APART IN THE BOTTOM OF THE TRENCH. BACKFILL AND COMPACT THE TRENCH AFTER STAPLING. APPLY SEED
TO COMPACTED SOIL AND FOLD REMAINING 12" PORTION OF MATTING BACK OVER SEED AND COMPACTED SOIL. SECURE MATTING
OVER COMPACTED SOIL WITH A ROW OF STAPLES/STAKES SPACED APPROXIMATELY 12" PART ACROSS THE WIDTH OF THE MATTING.
4. ROLL THE MATTING (A.) DOWN OR (B.) HORIZONTALLY ACROSS THE SLOPE. INSURE THAT THE APPROPRIATE SIDE OF THE MATTING
IS AGAINST THE SOIL SURFACE. ALL MATTING MUST BE SECURELY FASTENED TO SOIL SURFACE BY PLACING STAPLES/STAKES IN
APPROPRIATE LOCATIONS AS SHOWN IN THE MANUFACTURER'S STAPLE PATTERN GUIDE FOR THE PARTICULAR PRODUCT AND
APPLICATION. IN LOOSE SOIL CONDITIONS, THE USE OF STAPLE OR STAKE LENGTHS GREATER THAN 6" MAY BE NECESSARY TO
PROPERLY SECURE THE MATTING.
5. THE EDGES OF PARALLEL MATTING MUST BE STAPLED WITH APPROXIMATELY 6" OVERLAP DEPENDING ON MATTING TYPE.
6. CONSECUTIVE MATTING SPLICED DOWN THE SLOPE MUST BE PLACED END OVER END (SHINGLE STYLE - WITH THE UPPER MATTING
PLACED OVER THE TOP OF THE LOWER MATTING) WITH AN APPROXIMATE 12" OVERLAP. STAPLE THROUGH OVERLAPPED AREA,
APPROXIMATELY 12" APART ACROSS ENTIRE MATTING WIDTH.

1.THE PUMP STATION TANK SHALL HAVE SUFFICIENT CAPACITY TO ACCOMMODATE THE REQUIRED PUMP(S), AND THE SPECIFIED
DOSE VOLUME.
2.THE PUMP STATION STRUCTURE SHALL BE A WATERTIGHT, STEEL-REINFORCED, 5,000 PSI, PRE-CAST CONCRETE STRUCTURE
DESIGNED BY H-20 LOADING.
3. CONSTRUCTION OF THE PUMP STATION MAY REQUIRE TEMPORARY SHEETING AND/OR DEWATERING. THE CONTRACTOR SHALL
UTILIZE APPROPRIATE METHODS TO INSURE DRY CONDITIONS DURING INSTALLATION OF THE STRUCTURE. THE COST OF
TEMPORARY SHEETING AND/OR DEWATERING SHALL BE INCIDENTAL TO THE COST OF THE PUMP STATION.
4.THE PUMP STATION SHALL BE CONSTRUCTED TO MINIMIZE THE RISK OF FREEZING OF EFFLUENT IN THE PIPES OR STRUCTURE.
THIS INCLUDES BUT IS NOT LIMITED TO PROVIDING A DRAIN HOLE TO ALLOW THE FORCE MAIN TO DRAIN BACK INTO THE
STRUCTURE BETWEEN DOSES.
5.ALL PIPING WITHIN THE PUMP STATION SHALL BE SCHEDULE 80 PVC. THE CONTRACTOR MAY TRANSITION TO SCHEDULE 40 PVC
BEYOND THE EXTERIOR OF THE PUMP STATION.
6.ALL PIPE PENETRATIONS IN THE PUMP STATION STRUCTURE SHALL HAVE RUBBER BOOTS FOR WATERTIGHT SEALS AROUND THE
PIPES.
7.BACKFILL SIDES AND TOP OF TANK WITH SAND OR GRAVEL. ALL BACKFILL MATERIAL AROUND THE TANK SHALL BE THOROUGHLY
COMPACTED TO NOT LESS THAN 95% OF MAXIMUM DRY DENSITY AS DETERMINED BY THE AASHTO-T-99 STANDARD PROCTOR.
8.ALL ELECTRICAL WORK SHALL MEET THE REQUIREMENTS OF THE NATIONAL ELECTRIC CODE AND MATERIALS SHALL MEET U.L.
APPROVAL. CONDUIT SHALL BE PROVIDED AS REQUIRED BETWEEN THE PUMP STATION, THE ELECTRICAL SOURCE AND THE
CONTROL PANEL.
9.AT A MINIMUM, THE FOLLOWING ITEMS SHALL BE INCLUDED WITH THE PUMP STATION:
-ALARM, FLOATS, AND DUPLEX PUMP CONTROLS
-PUMP RUN TIME METER FOR EACH PUMP
-LIGHT AND AUDIBLE ALARMS

Bioretention Soil Mixture Specification:
1.DESCRIPTION.
1.1.THIS WORK SHALL CONSIST OF FURNISHING AND INSTALLING SOIL MIXTURE IN THE
BIORETENTION BASIN WHERE INDICATED ON THE CONSTRUCTION DOCUMENTS. WORK
SHALL BE CONSISTENT WITH VTRANS STANDARD SPECIFICATIONS SECTION 651, WITH
THE ADDITIONS AND MODIFICATIONS BELOW.
2.MATERIALS.
2.1.BIORETENTION SOIL SHALL CONSIST OF LOOSE, FRIABLE SOIL, FREE OF ICE, SNOW, AND
RUBBISH WITH NO ADMIXTURE OF REFUSE OR MATERIAL TOXIC TO PLANT GROWTH.
2.2.THE FINAL BIORETENTION SOIL MIXTURE SHALL MEET THE FOLLOWING PARAMETERS:
PH 5.5 - 7.5
MOISTURE CONTENT 25% - 55%
PHOSPHORUS INDEX 4-14 PPM
2.3.PHOSPHORUS INDEX SHALL BE DETERMINED BY MEHLICH -3 TESTING METHOD OR
APPROVED EQUIVALENT.
2.4.THE BIORETENTION SOIL MIXTURE SHALL BE A UNIFORM MIX, FREE OF STONES, STUMPS,
ROOTS OR OTHER SIMILAR OBJECTS LARGER THAN ONE (1) INCH IN DIAMETER
EXCLUDING MULCH.
2.5.NO OTHER MATERIALS OR SUBSTANCES SHALL BE MIXED OR DUMPED WITHIN THE
BIORETENTION AREA THAT MAY BE HARMFUL TO PLANT GROWTH, OR PROVE A
HINDRANCE TO THE PLANTING OR MAINTENANCE OPERATIONS.
2.6.THE BIORETENTION SOIL MIXTURE SHALL BE FREE OF ALL INVASIVE SPECIES, INCLUDING
KNOTWEED, PHRAGMITES, PURPLE LOOSESTRIFE, BERMUDA GRASS, QUACKGRASS,
JOHNSON GRASS, MUGWORT, NUTSEDGE, POISON IVY, CANADIAN THISTLE, TEATHUMB,
OR OTHER NOXIOUS WEEDS.
2.7.THE BIORETENTION SOIL SHALL MEET THE FOLLOWING REQUIREMENTS BY PERCENT OF
TOTAL WEIGHT:
SAND 85-88
SILT (0.002 - 0.05 MM)8-12
CLAY (LESS THAN 0.002 MM)0-2
COMPOST 3-5
2.8.SAND - THE SAND SHALL CONSIST OF CLEAN, INERT, HARD, DURABLE GRAINS OF
QUARTZ OR OTHER HARD, DURABLE ROCK, FREE FROM LOAM OR CLAY, SURFACE
COATINGS AND DELETERIOUS MATERIALS AND MEETING THE GRADATION
REQUIREMENTS OF VTRANS SPECIFICATIONS, TABLE 704.01A.
2.9.COMPOST - THE COMPOST SHALL BE DERIVED FROM ORGANIC WASTES SUCH AS LEAF
AND YARD WASTE RESIDUES. NO BIO-SOLIDS OR COMPOST DERIVED FROM FOOD
WASTES MAY BE USED. COMPOST SHALL BE A HIGHLY ORGANIC DARK BROWN TO BLACK
SPONGY RESIDUE RESULTING FROM THE WELL-AERATED COMPOSTING OF DECIDUOUS
ORGANIC MATERIALS, FREE OF PLANTS AND THEIR ROOTS, DEBRIS, STONES, OR OTHER
OBJECTS LARGER THAN 1-INCH IN ANY DIMENSION. IT SHOULD BE FREE OF OTHER
EXTRANEOUS MATTER AND SHALL BE UNCONTAMINATED BY FOREIGN MATTER,
SUBSTANCES HARMFUL TO PLANT GROWTH, AND FREE OF PETROLEUM
HYDROCARBONS. THE COMPOST SHALL HAVE THE FOLLOWING PROPERTIES:
PH 5.5 - 8.0
MOISTURE CONTENT 35% - 55%
SOLUBLE SALTS 4.0 MMHOS (DS)
C:N RATIO 15 - 30:1
PARTICLE SIZE µ
ORGANIC MATTER CONTENT > 25%
BULK DENSITY < 1,300 LBS / CUBIC YARD
FOREIGN MATTER < 1% (DRY WEIGHT)
3.SUBMITTALS.
3.1.BIORETENTION SOIL TEST REPORTS
3.1.1.PRIOR TO ORDERING BIORETENTION SOIL MIXTURE MATERIALS, SUBMIT SOIL TEST
REPORTS FOR TWO SEPARATE SAMPLES TO THE RESIDENT ENGINEER FOR REVIEW
AND APPROVAL. DO NOT ORDER MATERIALS UNTIL APPROVAL HAS BEEN OBTAINED.
DELIVERED MATERIALS SHALL BE FROM THE SAME SOURCE AS THE TESTED MATERIAL
AND VERIFIED AS SUCH.
3.1.2.THE CONTRACTOR SHALL EMPLOY A CERTIFIED TESTING LABORATORY TO TEST THE
MATERIAL, AND SHALL SUBMIT BIORETENTION SOIL MIXTURE TEST RESULT REPORTS
FOR REPRESENTATIVE SAMPLES TO THE REPRESENTATIVE. REPORTS SHALL INCLUDE:
3.1.3.LOCATION OF SAMPLE SOURCE, DATE OF SAMPLE.
3.1.4.TESTS FOR PHOSPHORUS, POTASSIUM, SOLUBLE SALTS, SOIL PH, MOISTURE
CONTENT, ORGANIC MATTER CONTENT, AND SOIL TEXTURE ANALYSIS IN
ACCORDANCE WITH THE CURRENT STANDARDS OF THE ASSOCIATION OF OFFICIAL
AGRICULTURE CHEMISTS.
3.1.5.TEST SHALL INCLUDE A SOIL PARTICLE GRADATION ANALYSIS AND CLASSIFICATION
OF SOIL.24" MIN.NOTE:
1.THE CONTRIBUTING DRAINAGE AREA TO EACH SYSTEM SHALL RECEIVE FINAL STABILIZATION PRIOR TO ACCEPTING RUNOFF.
2.THE LISTED AASHTO DESIGNATIONS ARE FOR GRADATIONS ONLY. THE STONE MUST ALSO BE CLEAN, CRUSHED, ANGULAR, WASHED STONE.
3.STORMTECH COMPACTION REQUIREMENTS ARE MET FOR 'A' LOCATION MATERIALS WHEN PLACED AND COMPACTED IN 6" (MAX) LIFTS FOR SC-310 USING TWO FULL COVERAGES WITH A VIBRATORY COMPACTOR.
4.WHERE INFILTRATION SURFACES MAY BE COMPROMISED BY COMPACTION, FOR STANDARD DESIGN LOAD CONDITIONS, A FLAT SURFACE MAY BE ACHIEVED BY RAKING OR DRAGGING WITHOUT COMPACTION EQUIPMENT. FOR SPECIAL
LOAD DESIGNS, CONTACT STORMTECH FOR COMPACTION REQUIREMENTS.
5.FOR ALL MATERIALS, THE CONTRACTOR SHALL SUBMIT A PARTICLE SIZE DISTRIBUTION REPORT TO THE ENGINEER FOR REVIEW AND APPROVAL PRIOR TO INSTALLATION.
6."ACCEPTABLE FILL MATERIALS" TABLE ABOVE PROVIDES MATERIAL LOCATIONS, DESCRIPTIONS, GRADATIONS, AND COMPACTION REQUIREMENTS FOR FOUNDATION, EMBEDMENT, AND FILL MATERIALS.
7.PERIMETER STONE MUST BE EXTENDED HORIZONTALLY TO THE EXCAVATION WALL FOR BOTH VERTICAL AND SLOPED EXCAVATION WALLS.
8.ONCE LAYER 'C' IS PLACED, ANY SOIL/MATERIAL CAN BE PLACED IN LAYER 'D' UP TO THE FINISHED GRADE. MOST PAVEMENT SUBBASE SOILS CAN BE USED TO REPLACE THE MATERIAL REQUIREMENTS OF LAYER 'C' OR 'D' AT THE SITE
DESIGN ENGINEER'S DISCRETION.
