ROADWAYS.
3.05 SILT FENCE:
A TEMPORARY SEDIMENT BARRIER CONSIS77NG OF A SYNTHETIC FILTER FABRIC STRETCHED ACROSS AND ATTACHED TO SUPPORTING POSTS AND
ENTRENCHED, TO INTERCEPT AND DETAIN SMALL AMOUNTS OF SEDIMENT FROM DISTURBED AREAS DURING CONSTRUC7ON OPERATIONS IN ORDER
TO PREVENT SEDIMENT FROM LEAVING THE SITE, AND TO DECREASE THE VELOCITY OF SHEET FLOWS AND LOW -TO -MODERATE LEVEL CHANNEL
FLOWS. HE SILT FENCE BARRIERS SHALL BE INSTALLED DOWN SLOPE OF AREAS WITH MINIMAL GRADES TO FILTER SEDIMENT LADEN RUNOFF
FROM SHEET FLOW AS INDICATED. THEY SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND MAINTAINED IN ACCORDANCE W/H THE
VIRGINIA EROSION & SEDIMENT CONTROL HANDBOOK (VESCH).
3.07 STORM DRAIN INLET PROTECTION.
A SEDIMENT FILTER OR AN EXCAVATED IMPOUNDING AREA AROUND A STORM DRAIN DROP INLET OR CURB INLET TO PREVENT SEDIMENT FROM
ENTERING STORM DRAINAGE SYSTEMS PRIOR TO PERMANENT STABILIZATION OF THE DISTURBED AREA. INLET PR07ECTION APPLIES WHERE
STORM DRAIN INLETS ARE TO BE MADE OPERA77ONAL BEFORE PERMANENT STABILIZATION OF THE CORRESPONDING DISTURBED DRAINAGE AREA.
3.08 CULVERT INLET PROTECTION.
A SEDIMENT FILTER OR AN EXCAVATED IMPOUNDING AREA AROUND A STORM CULVERT. TO PREVENT SEDIMENT FROM ENTERING STORM
CULVERTS PRIOR TO PERMANENT STABILIZATION OF THE DISTURBED AREA. INLET PR07ECT70N APPLIES WHERE STORM CULVERTS ARE EXIS77NG
OR TO BE MADE OPERATIONAL BEFORE PERMANENT STABILIZATION OF THE CORRESPONDING DRAINAGE AREA.
3.09 TEMPORARY DIVERSION DIKE.•
A TEMPORARY RIDGE OF COMPACTED SOIL CONSTRUCTED AT THE TOP OR BASE OF A SLOPING DISTURBED AREA. TO DIVERT STORM RUNOFF
FROM UPSLOPE DRAINAGE AREAS AWAY FROM UNPR07ECTED DISTURBED AREAS AND SLOPES TO A STABILIZED OUTLET TO DIVERT
SEDIMENT -LADEN RUNOFF FROM A DISTURBED AREA TO A SEDIMENT -TRAPPING FACILITY SUCH AS A SEDIMENT TRAP OR SEDIMENT BASIN. USE
WHEREVER STORMWATER RUNOFF MUST BE TEMPORARILY DIVERTED TO PR07ECT DISTURBED AREAS AND SLOPES OR RETAIN SEDIMENT ON S17F
DURING CONSTRUCTION. THESE STRUCTURES GENERALLY HAVE A LIFE EXPECTANCY OF 18 MONTHS OR LESS, WHICH CAN BE PROLONGED WlTH
PROPER MAINTENANCE.
3.12 DIVERSION:
A CHANNEL CONSTRUCTED ACROSS A SLOPE WITH A SUPPORTING EARTHEN RIDGE ON THE LOWER SIDE. TO REDUCE SLOPE LENGTH AND TO
INTERCEPT AND DIVERT STORMWATER RUNOFF TO STABILIZED OUTLETS AT NON -EROSIVE VELOCITIES. APPLIES WHERE RUNOFF FROM AREAS OF
HIGHER ELEVATION MAY DAMAGE PROPERTY CAUSE EROSION OR INTERFERE WITH THE ESTABLISHMENT OF VEGETATION ON LOWER AREAS
WHERE SURFACE AND/OR SHALLOW SUBSURFACE FLOW IS DAMAGING SLOPING UPLAND, AND WHERE THE SLOPE LENGTH NEEDS TO BE REDUCED
TO MINIMIZE SOIL LOSS.
3.13 TEMPORARY SEDIMENT TRAP. -
A TEMPORARY PONDING AREA FORMED BY CONSTRUCTING AN EARTHEN EMBANKMENT WITH A STONE OUTLET. TO DETAIN SEDIMENT -LADEN
RUNOFF FROM SMALL DISTURBED AREAS LONG ENOUGH TO ALLOW THE MAJORITY OF HE SEDIMENT TO SETTLE OUT. USE BELOW DISTURBED
AREAS WHERE THE TOTAL CONTRIBUTING DRAINAGE AREA IS LESS THAN 3 ACRES, WHERE THE SEDIMENT TRAP WILL BE USED NO LONGER THAN
18 MONTHS, AND IT MAY BE CONSTRUCTED EITHER INDEPENDENTLY OR IN CONJUNCTION W1H A TEMPORARY DIVERSION DIKE.
3.14 TEMPORARY SEDIMENT BASIN.
A TEMPORARY BARRIER OR DAM W1 H A CONTROLLED STORMWATER RELEASE STRUCTURE FORMED BY CONSTRUCTING AN EMBANKMENT OF
COMPACTED SOIL ACROSS A DRAINAGEWAK TO DETAIL SEDIMENT -LADEN RUNOFF FROM DISTURBED AREAS IN "WET" AND `DRY" STORAGE
LONG ENOUGH FOR THE MAJORITY OF THE SEDIMENT TO SETTLE OUT. APPLIES BELOW DISTURBED AREAS WHERE THE TOTAL CONTRIBUTING
DRAINAGE AREA IS EQUAL TO OR GREATER THAN THREE ACRES. THERE MUST BE SUFFICIENT SPACE AND APPROPRIATE TOPOGRAPHY FOR THE
CONSTRUCTION OF A TEMPORARY IMPOUNDMENT.
3.18 OUTLET PROTECTION:
STRUCTURALLY LINED APRONS OR OTHER ACCEPTABLE ENERGY DISSIPATING DEVICES PLACED AT THE OUTLETS OF PIPES OR PAVED CHANNEL
SECTIONS TO PREVENT SCOUR AT STORMWATER OUTLETS, TO PR07ECT THE OUTLET STRUCTURE, AND TO MINIMIZE THE P07EN77AL FOR
DOWNSTREAM EROSION BY REDUCING HE VELOCITY AND ENERGY OF CONCENTRATED STORMWATER FLOWS APPLICABLE TO THE OUTLETS OF
ALL PIPES AND ENGINEERED CHANNEL SECTIONS.
3.19 RIPRAP:
A PERMANENT, EROSION -RESISTANT GROUND COVER of LARGE, LOOSE, ANGULAR STONE WITH FILTER FABRIC OR GRANULAR UNDERLINING. TO
PR07ECT THE SOIL FROM THE EROSIVE FORCES OF CONCENTRATED RUNOFF, SLOW HE VELOCITY OF CONCENTRATED RUNOFF WHILE ENHANCING
THE P07EN77AL FOR INFILTRATION, AND TO STABILIZE SLOPES WITH SEEPAGE PROBLEMS, AND/OR NON -COHESIVE SOILS. USE WHEREVER SOIL
AND WATER INTERFACE AND THE SOIL CONDITIONS, WATER TURBULENCE AND VELOCITY, EXPECTED VEGETATIVE COVER, ETC., ARE SUCH THAT
THE SOIL MAY ERODE UNDER THE DESIGN FLOW CONDITIONS.
3.20 ROCK CHECK DAMS:
SMALL TEMPORARY STONE DAMS CONSTRUCTED ACROSS A SWALE OR DRAINAGE DITCH. TO REDUCE HE VELOCITY OF CONCENTRATED
STORMWATER FLOWS, HEREBY REDUCING EROSION OF HE SWALE OR DITCH. HIS PRACTICE ALSO TRAPS SEDIMENT GENERATED FROM
ADJACENT AREAS OR THE DITCH ITSELF, MAINLY BY PONDING OF HE STORMWATER RUNOFF. HIS PRACTICE, UTILIZING A COMBINATION OF
STONE SIZES, IS LIMITED TO USE IN SMALL OPEN CHANNELS WHICH DRAIN 10 ACRES OR LESS

GRAVEL WILL BE REMOVED AND CLEANED, OR IT WILL BE REPLACED.
C. ALL SILT FENCE BARRIERS WILL BE CHECKED REGULARLY FOR UNDERMINING OR
DETERIORATION OF THE FABRIC AND REPAIRED AS REQUIRED. SEDIMENT SHALL BE
REMOVED WHEN THE LEVEL OF SEDIMENT DEPOSITION REACHED HALF WAY TO THE
TOP OF THE BARRIER.
D. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO SEE THAT A GOOD STAND IS
MAINTAINED. AREAS SHOULD BE FERTILIZED AND RESEEDED AS NEEDED.

DETENTION BASIN'SWM T CONSTRUCTION NOTES:
FACILITY PLANTING SPECIFICATIONS:
1. THE DETENTION BASIN SHALL HAVE ATURF GROUND COVER, SUCH AS GRASS OR SOME OTHER FORM OF A VEGETATIVE GROUNDCOVER. LANDSCAPING BEYOND THIS
IS OPTIONAL AND IS NOT REQUIRED.
2. THE PROPOSED INTERIOR SIDE SLOPES OF THE BASIN SHALL BE A MAXIMUM OF 3:1 TO REDUCE THE RISK OF EROSION. THE PROPOSED FLOOR SLOPES SHALL BE
GRADED AT A MINIMUM OF 0.50%TO PROVIDE POSITIVE DRAINAGE AT ALL TIMES TO THE RISER STRUCTURE.
3. WOODY VEGETATION SHALL NOT BE PLANTED OR ALLOWED TO GROW WITHIN 15 FEET OF THE TOE OF THE EMBANKMENT NOR WITHIN 25 FEET OF THE PRINCIPAL
SPILLWAY STRUCTURE.
4. THE SOILS IN THE STORMWATER BUFFER AREA ARE OFTEN SEVERELY COMPACTED DURING THE CONSTRUCTION PROCESS, TO ENSURE STABILITY THE DENSITY OF THESE
COMPACTED SOILS CAN BE SO GREAT THAT IT EFFECTIVELY PREVENTS ROOT PENETRATION AND, THEREFORE, MAY LEAD TO PREMATURE MORTALITY OR LOSS OF
VIGOR. AS A RULE OF THUMB, PLANTING HOLES SHOULD BE THREE TIMES DEEPER AND WIDER THAN THE DIAMETER OF THE ROOTBALL FOR BALL -AND -BURLAP STOCK,
AND FIVE TIMES DEEPER AND WIDER FOR CONTAINER -GROWN STOCK.
5. EXTRA MULCHING AROUND THE BASE OF TREES AND SHRUBS IS STRONGLY RECOMMENDED AS A MEANS OF CONSERVING MOISTURE AND SUPPRESSING WEEDS.
CONTRACTOR REQUIREMENTS:
1. THE CONTRACTOR SHALL BE RESPONSIBLE FOR LAYOUT OF ALL WORK COVERED UNDER THESE PLANS.
2. LANDSCAPE CONTRACTOR SHALL REFER TO THE STANDARDIZED LANDSCAPE SPECIFICATIONS FOR THE STATE OF VIRGINIA FOR ADDITIONAL INFORMATION. THE
CONTRACTOR SHALL ABIDE BY ITS CONTENTS; HOWEVER ANY NOTES OR SPECIFICATIONS ON THE PLANS SHALL SUPERSEDE THOSE OUTLINED IN THE SPECIFICATIONS
MANUAL (COPIES ARE AVAILABLE FOR A FEE FROM THE VIRGINIA CHAPTER OF THE AMERICAN SOCIETY OF LANDSCAPE ARCHITECTS, VIRGINIA NURSERYMEN'S
ASSOCIATION, INC. AND THE VIRGINIA SOCIETY OF LANDSCAPE DESIGNERS). ALL DISCREPANCIES SHALL BE BROUGHT TO THE ATTENTION OF COLLINS ENGINEERING
PRIOR TO THE CORRESPONDING CONSTRUCTION ACTIVITY.
3. ALL PLANT MATERIAL SHALL MEET THE MINIMUM SPECIFICATIONS AND STANDARDS DESCRIBED IN THE CURRENT ISSUE OF THE AMERICAN STANDARD FOR NURSERY
STOCK, PUBLISHED BY THE AMERICAN ASSOCIATION OF NURSERYMEN, 1250 STREET, NW, SUITE 500, WASHINGTON, DC 20005.
4. THE CONTRACTOR SHALL VERIFY ALL DIMENSIONS IN THE FIELD AND NOTIFY THE DESIGNER OF ANY VARIANCE FROM THE PLAN.
5. THE LANDSCAPE CONTRACTOR IS RESPONSIBLE FOR VERIFYING THE LOCATION OF ANY ONSITE UTILITIES (CALL MISS UTILITY 1-800-552-7001 BEFORE ANY EXCAVATION).
6. REFER TO THE APPROVED FINAL SITE PLANS FOR ANY DETAILED SITE INFORMATION.
7. ALL WORK SHALL BE COORDINATED WITH OTHER PARTIES.
8. PLANTS WILL BE PREPARED FOR SHIPMENT IN A MANNER THAT WILL NOT CAUSE DAMAGE TO THE BARK, BUDS, BRANCHES, STEMS, OR OVERALL SHAPE OF THE STOCK.
CONTAINER GROWN PLANTS WILL BE TRANSPORTED IN THE CONTAINERS IN WHICH THEY HAVE GROWN.
9. ALL PLANT MATERIAL, UNLESS OTHERWISE SPECIFIED, SHALL BE UNIFORMLY BRANCHED AND HAVE A VIGOROUS ROOT SYSTEM. PLANT MATERIAL SHALL BE HEALTHY,
VIGOROUS, AND FREE FROM DEFECTS, DECAY, DISEASES, INSECT PEST EGGS, AND ALL FORMS OF INFESTATION. ALL PLANT MATERIAL SHALL BE FRESH, FREE FROM
TRANSPLANT SHOCK OR VISIBLE WILT. PLANTS DEEMED UNHEALTHY WILL BE REJECTED.
10. ALL CONTAINER STOCK SHALL HAVE BEEN PROPAGATED IN A CONTAINER LONG ENOUGH FOR THE ROOT SYSTEM TO HAVE DEVELOPED SUFFICIENTLY TO HOLD ITS SOIL.
CONTAINER STOCK WITH POORLY DEVELOPED ROOT SYSTEMS WILL NOT BE ACCEPTED.
11. PLANTS NOT INSTALLED ON THE DAY OF ARRIVAL ON SITE SHALL BE STORED AND PROTECTED BY THE CONTAINER. OUTSIDE STORAGE AREAS WILL BE SHADED AND
PROTECTED FROM THE WIND AND SUN. PLANTS STORED ON SITE SHALL BE PROTECTED FROM ANY DRYING AT ALL TIMES BY COVERING THE BALLS OR ROOTS WITH
MOIST SAWDUST, WET BURLAP, WOOD CHIPS, SHREDDED BARK, PEAT MOSS, OR OTHER SIMILAR MULCHING MATERIAL.
12. THE OWNER RESERVES THE RIGHT TO SUBSTITUTE PLANT MATERIAL TYPE, SIZE AND/OR QUANTITY. ANY SUBSTITUTIONS MUST BE APPROVED BY THE INSPECTOR
INITIALLY, AND THEN THE DESIGNER.
13. MINOR FIELD ADJUSTMENTS MAYBE NECESSARY DUE TO SITE CONDITIONS (EX: ROOTBALL AND UTILITY CONFLICT). MAJOR ADJUSTMENTS MUST BE APPROVED BY THE
DESIGNER.
14. NO PLANTING SHALL OCCUR WHEN THE SOIL IS FROZEN.
15. PLANT MATERIAL SHALL BE PLACED IN EXISTING SOIL WITH EACH PLANTING PIT EXCAVATED TO A SIZE SUFFICIENT TO CONTAIN THE ENTIRE ROOT BALL OR ROOT MASS,
WITHOUT CRAMPING ROOTSTOCK.
16. THE CONTRACTOR SHALL MAINTAIN A ONE (1) CALENDAR YEAR 90% CARE AND REPLACEMENT WARRANTY FOR ALL PLANTINGS. THE PERIOD OF CARE AND
REPLACEMENT SHALL BEGIN AFTER INSPECTION AND APPROVAL OF THE COMPLETE INSTALLATION OF ALL PLANTS AND CONTINUE FOR ONE CALENDAR YEAR.
17. THE CONTRACTOR IS RESPONSIBLE FOR REMOVAL AND DISPOSAL OF TRASH AND DEBRIS WITHIN THE LIMITS OF THE PLANTING ON A DAILY BASIS.
18. THE CONTRACTOR WILL NOT BE RESPONSIBLE FOR PLANT MATERIAL THAT HAS BEEN DAMAGED BY VANDALISM, FIRE, OR OTHER ACTIVITIES BEYOND THE
CONTRACTOR's CONTROL.
FACILITY CONSTRUCTION
1. THE DETENTION BASIN MAY SERVE AS A SEDIMENT BASIN AND/OR TRAP DURING PROJECT CONSTRUCTION. IF THIS IS DONE, THE VOLUME SHALL BE BASED ON THE
MORE STRINGENT SIZING RULE (EROSION AND SEDIMENT CONTROL REQUIREMENTS VS. STORMWATER TREATMENT REQUIREMENTS). INSTALLATION OF THE
PERMANENT RISER SHALL BE INITIATED DURING THE CONSTRUCTION PHASE, AND DESIGN ELEVATIONS SHALL BE SET WITH FINAL CLEANOUT OF THE SEDIMENT BASIN
AND CONVERSION TO THE POST -CONSTRUCTION FACILITY IN MIND. APPROPRIATE PROCEDURES SHALL BE IMPLEMENTED TO PREVENT DISCHARGE OF TURBULENT
WATERS WHEN THE BASIN IS BEING CONVERTED TO AN DETENTION BASIN.
2. THE DETENTION BASIN SHALL ONLY BE CONSTRUCTED AFTER THE CONTRIBUTING DRAINAGE AREA TO THE FACILITY IS COMPLETELY STABILIZED. IF THE SITE OF THE
PROPOSED SWIM FACILITY WILL BE USED AS A SEDIMENT TRAP OR BASIN DURING THE CONSTRUCTION PHASE, THEN THE FACILITY WILL BE DEWATERED, DREDGED AND
RE -GRADED TO DESIGN DIMENSIONS AFTER THE ORIGINAL SITE CONSTRUCTION IS COMPLETE. MODIFICATIONS SHALL BE MADE TO THE RISER, ORIFICES AND BARRELS
AS REQUIRED SO THAT THEY ARE CONSISTENT WITH THE FINAL CONSTRUCTION SPECIFICATIONS.
3. THE CONTRACTOR SHALL ASSEMBLE CONSTRUCTION MATERIALS ON -SITE, MAKING SURE THEY MEET DESIGN SPECIFICATIONS AND ARE PREPARED AT STAGING AREAS
WHEN POSSIBLE.
4. THE CONTRACTOR SHALLCLEARAND STRIPTHE PROJECTAREA IF REQUIREDTOTHE DESIRED SUB -GRADE.
5. INSTALL E&S CONTROLS PRIOR TO CONSTRUCTION OF THE BASIN, INCLUDING TEMPORARY DE -WATERING DEVICES AND STORMWATER DIVERSION PRACTICES. ALL
AREAS SURROUNDING THE BASIN THAT ARE GRADED OR DENUDED DURING CONSTRUCTION SHALL BE PLANTED WITH TURF GRASS, NATIVE PLANTINGS, OR OTHER
APPROVED METHODS OF SOIL STABILIZATION.
6. CONTRACTOR SHALL EXCAVATE THE CORE TRENCH AND INSTALL THE SPILLWAY PIPE DURING THE ESC PHASE.
7. CONTRACTOR SHALL ALSO INSTALL THE RISER, OUTFLOW STRUCTURE AND/OR THE BARREL(s) WITH PERMANENT COLLARS DURING THE ESC PHASE TO ENSURE THE TOP
INVERT OF THE OVERFLOW WEIR 15 CONSTRUCTED LEVEL AT THE DESIGN ELEVATION.
8. THE CONTRACTOR SHALL CONSTRUCT THE EMBANKMENT AND ANY INTERNAL BERMS IN 8-TO 12-INCH LIFTS, COMPACTION SHALL BE COMPLETED IN LIFTS WITH
APPROPRIATE EQUIPMENT. THE CONTRACTOR SHALL ALSO ADHERE TO THE CLAY LINER SPECIFICATIONS OUTLINED IN TABLE 14.4 BELOW:

9. UPON COMPLETION OF THE EMBANKMENT GRADING, THE CONTRACTOR SHALL EXCAVATE/GRADE UNTIL THE APPROPRIATE ELEVATION AND DESIRED CONTOURS ARE
ACHIEVED FORTH E BOTTOM AND SIDE SLOPES OF THE BASIN.
10. CONTRACTOR SHALL THEN CONSTRUCT THE EMERGENCY SPILLWAY IN CUT OR STRUCTURALLY STABILIZED SOILS.
11. THE CONTRACTOR SHALL THEN FINISH CONSTRUCTION OF ALL OUTLET STRUCTURES, INCLUDING DOWNSTREAM RIP -RAP APRON PROTECTION.
12. THE CONTRACTOR SHALL NEXT STABILIZE EXPOSED SOILS BY HYDROSEEDING OR SEEDING OVER STRAW.
13. THE CONTRACTOR SHALL THEN INSTALL THE APPROPRIATE BASIN LANDSCAPING IN ACCORDANCE WITH THE APPROVED PLANS.
FACILITY MAINTENANCE:
MAINTENANCE OF THE DETENTION BASIN IS DRIVEN BY ANNUAL INSPECTIONS THAT EVALUATE THE CONDITION AND PERFORMANCE OF THE FACILITIES. DURING THESE
INSPECTIONS THE FOLLOWING TASKS SHALL BE PERFORMED BY THE CONTRACTOR IN THE FIRST YEAR FOLLOWING INSTALLATION, AND THE OWNER THEREAFTER:
1. MEASURE SEDIMENT ACCUMULATION LEVELS IN THE BASIN.
2. MONITOR THE GROWTH OF THE GROUNDCOVER AND ANY TREES AND SHRUBS PLANTED, AS APPLICABLE. RECORD THE SPECIES AND THEIR APPROXIMATE COVERAGE,
AND NOTE THE PRESENCE OF ANY INVASIVE PLANT SPECIES, AS APPLICABLE.
