TO AVOID COMPACTING THE DRAINAGE MEDIA, LIGHT EQUIPMENT AND CONSTRUCTION TECHNIQUES THAT MINIMIZE COMPACTION SHOULD BE USED. RUNOFF SHALL NOT BE DIRECTED INTO AN INFILTRATION DEVICE UNTIL THE DRAINAGE AREA IS STABILIZED A CONSTRUCTION NSUC TR TION SEQUENCE MUST BE FOLLOWED THAT REFLECTS THE NEED TO STABILIZE THE INFILTRATION DEVICE. THE LONGEVITY OF INFILTRATION DEVICES IS STRONGLY INFLUENCED BY THE CARE TAKEN DURING CONSTRUCTION. A MINIMUM OF ONE OBSERVATION WELL SHALL BE INCLUDED IN THE DESIGN OF AN INFILTRATION SYSTEM TO PERIODICALLY VERIFY THAT THE DRAINAGE MEDIA IS FULLY DRAINING. THE MONITORING WELL SHALL CONSIST OF A 4-INCH TO 6-INCH DIAMETER, PERFORATED POLYVINYL CHLORIDE (PVC) PIPE WITH A LOCKING CAP. THE WELL SHOULD BE PLACED NEAR THE CENTER OF THE FACILITY OR IN THE GENERAL LOCATION OF THE LOWEST POINT WITHIN THE FACILITY, WITH THE INVERT AT THE EXCAVATED BOTTOM OF THE FACILITY. .

RCP OUTFALL (REFER TO GRADING PLAN FOR PROPOSED ELEVATIONS) PLEASE REFER TO SECTION 7.0, GENERAL BMP MAINTENANCE, FOR INFORMATION ON TYPES OF MAINTENANCE, TYPICAL FREQUENCY, AND SPECIFIC MAINTENANCE TASKS THAT ARE COMMON TO ALL BMPS. THE FOLLOWING INFORMATION IS MAINTENANCE THAT IS SPECIFIC TO INFILTRATION DEVICES. FOR THE FIRST YEAR OF OPERATION, INSTALLATIONS SHOULD BE INSPECTED MONTHLY AND AFTER EACH MAJOR STORM. AFTER THE FIRST YEARQUARTERLY INSPECTIONS PREFERABLY CONDUCTED AFTER A STORM ARE RECOMMENDED. MAINTENANCE IS VERY IMPORTANT FOR INFILTRATION DEVICES. PROPERTY OWNERS SHOULD BE EDUCATED IN THE FUNCTION AND MAINTENANCE REQUIREMENTS OF INFILTRATION DEVICES. ESPECIALLY IMPORTANT IS THE MAINTENANCE OF VEGETATED AREAS THAT DRAIN TO THE INFILTRATION SYSTEM. AREAS THAT ARE ALLOWED TO BECOME BARE AND UNVEGETATED WILL CONTRIBUTE EXCESS SEDIMENT TO THE INFILTRATION SYSTEM AND HASTEN ITS FAILURE. ANY SEDIMENT DEPOSITS IN PRETREATMENT DEVICES SHOULD BE REMOVED AT LEAST ANNUALLY. THE SURFACE OF INFILTRATION SYSTEMS MUST BE KEPT IN GOOD CONDITION. COLONIZATION BY GRASS OR OTHER PLANTS SHOULD BE DISCOURAGED, SINCE THIS CAN LEAD TO REDUCED SURFACE INFILTRATION RATES. IN MANY INSTANCES, IT IS CONVENIENT TO COVER INFILTRATION TRENCHES WITH CONCRETE GRID PAVERS OR SIMILAR PERMEABLE PAVING SYSTEMS THAT CAN BE REMOVED EASILY AND REPLACED AS NECESSARY TO SERVICE THE TRENCH. IN ORDER TO MONITOR PERFORMANCE OF THE INFILTRATION DEVICE, OBSERVATIONS SHOULD BE CONDUCTED TO DETERMINE HOW LONG IT TAKES RETAINED WATER TO INFILTRATE INTO THE SOIL AFTER A STORM EVENT. THE DETERMINATION CAN BE MADE IN TWO WAYS. THE MOST INFORMATIVE WAY IS TO READ THE WATER LEVEL SEVERAL TIMES OVER A PERIOD OF DAYS AFTER A LARGE STORM. THE ALTERNATIVE IS A "ONE -STOP" METHOD, WHERE A SINGLE READING IS TAKEN AND COMPARED WITH THE LOCAL RAINFALL RECORD- ALTHOUGH LESS ACCURATE THAN THE MULTIPLE READING METHOD, THE ONE -STOP METHOD WILL STILL ALLOW SIGNIFICANT DETERIORATION IN PERFORMANCE TO BE RECOGNIZED. THE TOP SEVERAL INCHES OF DRAINAGE MEDIA AND THE FILTER CLOTH ALONG THE TOP OF THE DRAINAGE MEDIA SHOULD BE REPLACED ANNUALLY OR AT LEAST WHEN THE DEWATERING TIME IS LONGER THAN 5 DAYS. IF AFTER REPLACING THE TOP MEDIA THE INFILTRATION RATE IS STILL NOT IN THE ACCEPTABLE RANGE, THE ENTIRE FACILITY MUST BE DISMANTLED AND RECONSTRUCTED. PROPER DISPOSAL OF THE MATERIALS REMOVED IS NECESSARY; THE AGGREGATE AND CLOTH SHOULD BE APPROPRIATELY PACKAGED AND DELIVERED TO THE LOCAL LANDFILL, IF THE OPERATING AUTHORITY APPROVES THE DISPOSAL. SINCE INFILTRATION TRENCHES AND INFILTRATION BASINS HAVE DIFFERENT CONFIGURATIONS AND MAINTENANCE NEEDS, AN APPROPRIATE SAMPLE OPERATION AND MAINTENANCE TABLE IS OFFERED FOR EACH ONE. 38 1 10 X 1 1 /4 OPENINGS o0 O O O o00 91/4R.J 25 35 3/41 00000000000 35 3/4 �OOOOD�0�00 2,R 5 MAX. 23 1 /Z oa00000aoco 1 � 1 MAX �GRATE 26� O O O C O 0 0 0a 0 0 0 �--- 27 1 /4 I 38 1 1 3 3/4 6 1 /4 NOTES: 1- MATERIAL: ASTM-A48 CLASS 'I 35B GRAY IRON. 2- FRAME WT: 270 _BS.

No heavy equipment shall be used within the perimeter of the bioretention facility before, during, or after the placement of the BSM. The BSM shall be placed in horizontal layers not to exceed 12 inches for the entre area of the bioretention facility. The BSM shall be compacted by saturating the entire area of the bioretention facility after each lift of BSM is placed until water flows from the underdrain. Water for saturation shall be applied by spraying or Sprinkling. An appropriate sediment control device shall be used to treat any sediment —laden water discharged from the inderdrain. If the BSM becomes contaminated during the construction of the facility, the contaminated material shall be removes and replaced with uncontaminated material at no additional cost to the Owner. Final grading of the BSM shall be performed after a 24—hour settling period. Final elevations shall be within 2 inches of elevations shown on the Contract Plans. The Bioretention Soil Mixture (BSM) shall be a uniform mix, free of stones, stumps, roots or other similar objects larger than two inches excluding mulch. 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. BSM must have a P—index of 10 to 30 Prior to placing the underdrain and the BSM, the bottom of the excavation shall be roto—tilled to a minimum depth of 6 inches to alleviate any compaction of the facility tottom. Any substitute method for roto—tilling must be approved by the Engineer prior to use. Any ponded water shall be removed from the bottom of the facility and the soil shall be friable before roto—tilling. Grass sod shall be used in bioretention area.

TO AVOID COMPACTING THE DRAINAGE MEDIA, LIGHT EQUIPMENT AND CONSTRUCTION TECHNIQUES THAT MINIMIZE COMPACTION SHOULD BE USED. RUNOFF SHALL NOT BE DIRECTED INTO AN INFILTRATION DEVICE UNTIL THE DRAINAGE AREA IS STABILIZED. A CONSTRUCTION SEQUENCE MUST BE FOLLOWED THAT REFLECTS THE NEED TO STABILIZE THE INFILTRATION DEVICE. THE LONGEVITY OF INFILTRATION DEVICES IS STRONGLY INFLUENCED BY THE CARE TAKEN DURING CONSTRUCTION. A MINIMUM OF ONE OBSERVATION WELL SHALL BE INCLUDED IN THE DESIGN OF AN INFILTRATION SYSTEM TO PERIODICALLY VERIFY THAT THE DRAINAGE MEDIA IS FULLY DRAINING. THE MONITORING WELL SHALL CONSIST OF A 4-INCH TO 6-INCH DIAMETER, PERFORATED POLYVINYL CHLORIDE (PVC) PIPE WITH A LOCKING CAP. THE WELL SHOULD BE PLACED NEAR THE CENTER OF THE FACILITY OR IN THE GENERAL LOCATION OF THE LOWEST POINT WITHIN THE FACILITY, WITH THE INVERT AT THE EXCAVATED BOTTOM OF THE FACILITY. MAINTENANCE NOTES PLEASE REFER TO SECTION 7.0, GENERAL BMP MAINTENANCE, FOR INFORMATION ON TYPES OF MAINTENANCE, TYPICAL FREQUENCY, AND SPECIFIC MAINTENANCE TASKS THAT ARE COMMON TO ALL BMPS. THE FOLLOWING INFORMATION IS MAINTENANCE THAT IS SPECIFIC TO INFILTRATION DEVICES. FOR THE FIRST YEAR OF OPERATION, INSTALLATIONS SHOULD BE INSPECTED MONTHLY AND AFTER EACH MAJOR STORM. AFTER THE FIRST YEAR, QUARTERLY INSPECTIONS, PREFERABLY CONDUCTED AFTER A STORM, ARE RECOMMENDED. MAINTENANCE IS VERY IMPORTANT FOR INFILTRATION DEVICES. PROPERTY T OWNERS SHOULD BE EDUCATED IN THE FUNCTION AND MAINTENANCE REQUIREMENTS OF INFILTRATION DEVICES. ESPECIALLY IMPORTANT IS THE MAINTENANCE OF VEGETATED AREAS THAT DRAIN TO THE INFILTRATION RATION SYSTEM. AREAS THAT ARE ALLOWED TO BECOME U G 0 E BARE E AND NVE ETATED WILL CONTRIBUTE EXCESS SEDIMENT TO THE INFILTRATION SYSTEM AND HASTEN ITS FAILURE. ANY SEDIMENT DEPOSITS IN PRETREATMENT DEVICES SHOULD BE REMOVED AT LEAST ANNUALLY. THE SURFACE OF INFILTRATION SYSTEMS MUST K E S US BE KEPT IN GOOD CONDITION. COLONIZATION BY GRASS OR OTHER PLANTS SHOULD BE DISCOURAGED, SINCE THIS CAN LEAD TO REDUCED SURFACE INFILTRATION RATES. IN MANY INSTANCES, IT IS CONVENIENT TO COVER INFILTRATION TRENCHES WITH CONCRETE GRID PAVERS OR SIMILAR PERMEABLE PAVING SYSTEMS THAT CAN BE REMOVED EASILY AND REPLACED AS NECESSARY TO SERVICE THE TRENCH. IN ORDER TO MONITOR PERFORMANCE OF THE INFILTRATION DEVICE, OBSERVATIONS SHOULD BE CONDUCTED TO DETERMINE HOW LONG IT TAKES RETAINED WATER TO INFILTRATE INTO THE SOIL AFTER A STORM EVENT. THE DETERMINATION CAN BE MADE IN TWO WAYS. THE MOST INFORMATIVE WAY IS TO READ THE WATER LEVEL SEVERAL TIMES OVER A PERIOD OF DAYS AFTER A LARGE STORM. THE ALTERNATIVE IS A "ONE -STOP" METHOD, WHERE A SINGLE READING IS TAKEN AND COMPARED WITH THE LOCAL RAINFALL RECORD. ALTHOUGH LESS ACCURATE THAN THE MULTIPLE READING METHOD, THE ONE -STOP METHOD WILL STILL ALLOW SIGNIFICANT DETERIORATION IN PERFORMANCE TO BE RECOGNIZED. THE TOP SEVERAL INCHES OF DRAINAGE MEDIA AND THE FILTER CLOTH ALONG THE TOP OF THE DRAINAGE MEDIA SHOULD BE REPLACED ANNUALLY OR AT LEAST WHEN THE DEWATERING TIME IS LONGER THAN 5 DAYS. IF AFTER REPLACING THE TOP MEDIA THE INFILTRATION RATE IS STILL NOT IN THE ACCEPTABLE RANGE, THE ENTIRE FACILITY MUST BE DISMANTLED AND RECONSTRUCTED. PROPER DISPOSAL OF THE MATERIALS REMOVED IS NECESSARY; THE AGGREGATE AND CLOTH SHOULD BE APPROPRIATELY PACKAGED AND DELIVERED TO THE LOCAL LANDFILL, IF THE OPERATING AUTHORITY APPROVES THE DISPOSAL.

Set the plants upright, ih the center of the pit. The bottom of the root mass should be resting on undisturbed Boll. I. Place the badkflll around the base and sides of the root mass, and work each layer to settle backflll and to eliminate Yoids and air pockets. When pit Is approximately 2/3 full, water thoroughly before placing remainder of the backflll. Water again after placing final layer of backfill. J. Broken or damaged pats will be cut back to undamaged tissue, leaving as much green basal time as possible above the roots. If more than fifty percent (50%) of the plant is damaged than contractor shall replace the plant. CONTAINER STOCK / RARE ROOT A. Stock shall have been grown in a container long enough for the root system to have developed sufficiently to hold Its soil together once removed from the container. B. Container plants will need to be watered regularly and placed In shady conditions until planting occurs. C. Bore root plants are for Immediate planting, otherwise seer 0) below. D. If bare roots specimens are not to be planted within four (4) days, temporary holding of bore root specimens are to be covered entirely by a suitable medkim (etc, soli, sawdust, mulch or the like) and watered regularly so as to not dry out.
