floatables that tend to accumulate in the forebay, micropool, and on the bottom of ED ponds.
(PLAN
Frequent sediment removal from the forebay is essential to maintain the function and performance of an
ED pond. For planning purposes maintenance plaris should anticipate cleanouts every 5 to 7 years, or when
inspections indicate that 50% of the forebay capacity has been filled. (Absent an upstream eroding channel
or other source of sediment, the frequency of sediment removal should decrease as the drainage area
stabilizes.) As noted above, the designer should also check to see whether removed sediments can be %
spoiled (deposited) on-site or must be hauled away. Sediments excavated from ED ponds are typically not TRUE NORTH
considered toxic or hazardous, and can be safely disposed by either land application or land filling.

BIORETENTION AREA NOTES:
1. BIORETENTION AREAS SHALL BE PROVIDED IN ACCORDANCE NTH THE VIRGINIA DEQ
STORMWATER DESIGN SPECIFICATION #9, VERSION 2.0.
2. COMPONENTS AND DIMENSIONS DEPICTED IN BIORETENTION AREA #1, SECTION #1, SHALL
APPLY TO BIORETENTION AREA #2 WITH THE FOLLOWING EXCEPTIONS:
2.1. BiORETENTION AREA #2 IS 15' IN WIDTH.
2.2. TOP OF BIORETENTiON AREA #2 IS 423.00.
3. GENERAL FILTER MEDIA COMPOSITION:
3.1. 80-90% SAND
3.2. 10-20% SOIL FINES
3.3. 3-5% ORGANIC MATTER
4. FILTER MEDiA TESTING:
4.1. AVAILABLE P BETWEEN L+ AND M, PER DCR 2005 NUTRIENT MANAGEMENT CRITERIA
4.2. FILTER MEDIA SHALL BE CERTIFIED BY THE SUPPLIER.
5. GEOTEXTiLE FABRiC/LINER:
5.1. NONWOVEN GEOTEXTILE FABRIC W/ FLOW RATE > 110 GAL/MIN/SF

BIORETENTION PLAN
(SEE SHEET L-102)
BIORETENTION AREA CONSTRUCTION NOTES:
STEP 1, CONSTRUCTION OF THE BIORETENTION AREA MAY ONLY BEGiN AFTER THE ENTIRE
CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED WITH VEGETATION.
STEP 2. CONTRACTOR SHALL SCHEDULE A PRECONSTRUCTION MEETING WITH THE ENGINEER,
AT WHiCH TIME, THE BOUNDARIES OF THE CONTRIBUTING DRAINAGE AREA AND
THE ACTUAL INLET ELEVATIONS WILL BE VERIFIED TO ENSURE THEY CONFORM TO
THE DESIGN.
STEP 3. TEMPORARY E&S CONTROLS SHALL BE PROVIDED AS REQUIRED DURING
CONSTRUCTION OF THE BIORETENTION AREA TO DIVERT STORMWATER AWAY FROM
THE BIORETENTION AREA UNTIL IT IS COMPLETED. SPECIAL PROTECTION MEASURES
SUCH AS EROSION CONTROL FABRICS MAY BE NEEDED TO PROTECT VULNERABLE
SIDE SLOPES FROM EROSION DURING THE CONSTRUCTION PROCESS.
STEP 4. ANY PRE-TREATMENT CELLS SHALL BE EXCAVATED AND SEALED TO TRAP
SEDIMENTS.
STEP 5. EXCAVATORS OR BACKHOES SHALL WORK FROM THE SIDES TO EXCAVATE THE
BIORETEN11ON AREA TO ITS APPROPRIATE DESIGN DEPTH AND DIMENSIONS.
EXCAVATING EQUIPMENT SHALL HAVE SCOOPS WITH ADEQUATE REACH SO THEY
DO NOT SIT INSIDE THE FOOTPRINT OF THE BIORETENTION AREA.
STEP 6. RIP THE BOTTOM SOILS OF THE BIORETENTION TO A DEPTH OF 6 TO 12 INCHES
TO PROMOTE GREATER INFILTRATION.
STEP 7. PLACE GEOTEXTTLE FABRIC ON THE SIDES OF THE BIORETENTION AREA WITH A
6 -INCH OVERLAP ON THE SIDES. PLACE THE APPROPRIATE DEPTH OF #57
STONE ON THE BOTTOM, PROVIDE THE PERFORATED UNDERDRAIN PIPE, PROVIDE
#57 STONE AND GEOTEXTiLE OVER PIPE, AND PROVIDE CHOKER STONE LAYER.
STEP 8. OBTAIN THE SOIL MEDIA FROM A QUALIFIED VENDOR, AND STORE IT ON AN
ADJACENT IMPERVIOUS AREA OR PLASTIC SHEETING. AFTER VERIFYING THAT THE
MEDIA MEETS THE SPECIFICATIONS, APPLY THE MEDIA IN 12 -INCH LIFTS UNTIL
THE DESIRED TOP ELEVATION OF THE BIORETENTION AREA IS ACHIEVED. WAIT 3-5
DAYS TO CHECK FOR SETTLEMENT, AND ADD ADDITIONAL MEDiA, AS NEEDED, TO
ACHIEVE THE DESIGN ELEVATION.
STEP 9, PREPARE PLANTING HOLES FOR ANY TREES AND SHRUBS, INSTALL THE
VEGETATION, AND WATER ACCORDINGLY. INSTALL ANY TEMPORARY IRRIGATION,
STEP 10. PROVIDE MULCH LAYER.

BIORETENTION PLANTING NOTES
(DERIVED FROM VA DEQ STORMWATER DESIGN SPECIFICATION #9, BIORETENTION)
BIO -FILTER PLANTING SPECIFICATIONS:
1. ROOT STOCK OF THE PLANT MATERIALS SHALL BE KEPT MOIST DURING TRANSPORT FROM THE SOURCE TO THE JOB SITE AND UNTIL PLANTED.
2. WALLS OF PLANTING PIT SHALL BE SLOPED OUTWARD,
3. THE DIAMETER OF THE PLANTING PIT MUST BE A MINIMUM OF SIX INCHES (6") LARGER THAN THE DIAMETER OF THE BALL OF THE TREE.
4. THE PLANTING PIT SHALL BE DEEP ENOUGH TO ALLOW JTH OF THE OVERALL DIMENSION OF THE ROOT BALL TO BE ABOVE GRADE LOOSE SOIL AT THE BOTTOM OF
THE PIT SHALL BE TAMPED BY HAND.
5. THE APPROPRIATE AMOUNT OF FERTILIZER IS TO BE PLACED AT THE BOTTOM OF THE PIT (SEE BELOW FOR FERTILIZER RATES)
6. THE PLANT SHALL BE REMOVED FROM THE CONTAINER AND PLACED IN THE PLAN'nNG PIT BY LIFTING AND CARRYING THE PLANT BY ITS BALL (NEVER LIFT BY
BRANCHES OR TRUNK).
7. SET THE PLANT STRAIGHT AND IN THE CENTER OF THE PIT SO THAT APPROXIMATELY 1/8TH OF THE DIAMETER OF THE ROOT FLARE IS ABOVE THE FINAL GRADE.
8. BACKFILL PLANTING PIT WITH EXISTING SOIL.
9. MAKE SURE PLANT REMAINS STRAIGHT DURING BACKFILLING PROCEDURES.
10. REMOVE ANY SOIL FROM THE TOP OF THE ROOT FLARE. NEVER COVER THE TOP OF THE BALL WITH SOIL. MOUND SOIL AROUND THE EXPOSED BALL. TREES SHALL
BE PLANTED WITH THE ROOT FLARE 2"-4" ABOVE FINISH GRADE.
11, TREES SHALL BE BRACED BY USING 2" BY 2" WHITE OAK STAKES. STAKES SHALL BE PLACED PARALLEL TO WALKWAYS AND BUILDINGS. STAKES ARE TO BE
EQUALLY SPACED ON OUTSIDE OF THE TREE BALL UTILIZING ARBOR TIES TO SECURE THE TREE, ALLOWING 3"-5" OF TREE MOVEMENT.
