THE LANDSCAPE PROFESSIONAL MANAGING THE WETLAND MUSTUNDERSTAND THE BIOLOGICAL REQUIREMENTS OF THE PLANTS ANDMANAGE WATER LEVELS APPROPRIATELY TO PROVIDE FOR THEIR NEEDS.2. ALTHOUGH WETLAND PLANTS REQUIRE WATER FOR GROWTH ANDREPRODUCTION, THEY CAN BE KILLED BY DROWNING IN EXCESSIVELYDEEP WATER. USUALLY, INITIAL GROWTH IS BEST WITH TRANSPLANTEDPLANTS IN WET, WELL-AERATED SOIL. OCCASIONAL INUNDATIONFOLLOWED BY EXPOSURE TO AIR OF THE MAJORITY OF THE VEGETATIONENABLES THE PLANTS TO OBTAIN OXYGEN AND GROW OPTIMALLY.CONVERSELY, FREQUENT SOIL SATURATION IS IMPORTANT FOR WETLANDPLANT SURVIVAL.3. DRAMATIC SHIFTS CAN OCCUR AS PLANT SUCCESSION PROCEEDS. THEPLANT COMMUNITY REFLECTS MANAGEMENT AND CAN INDICATEPROBLEMS OR THE RESULTS OF IMPROVEMENTS. FOR EXAMPLE, AREQUIREMENT OF SUBMERGED AQUATIC PLANTS, SUCH AS PONDWEED(POTAMOGETON SPP.), IS LIGHT PENETRATION INTO THE WATER COLUMN.THE DISAPPEARANCE OF THESE PLANTS MAY INDICATE INADEQUATEWATER CLARITY. THE APPEARANCE OF INVASIVE SPECIES ORDEVELOPMENT OF A MONOCULTURE IS ALSO A SIGN OF A PROBLEM WITHTHE AQUATIC/SOIL/VEGETATIVE REQUIREMENTS. FOR INSTANCE, MANYINVASIVE SPECIES CAN QUICKLY SPREAD AND TAKE OVER A WETLAND. IFCATTAILS BECOME INVASIVE, THEY CAN BE REMOVED BY A LICENSEDAQUATIC PESTICIDE APPLICATOR BY WIPING AQUATIC GLYPHOSATE, ASYSTEMIC HERBICIDE, ON THE CATTAILS.4. UNLIKE MAINTENANCE REQUIREMENTS FOR WET OR DRY STORMWATERPONDS, SEDIMENT SHOULD ONLY BE SELECTIVELY REMOVED FROMSTORMWATER WETLANDS, PRIMARILY FROM THE FOREBAY.SEDIMENTREMOVAL DISTURBS STABLE VEGETATION COVER AND DISRUPTSFLOWPATHS THROUGH THE WETLAND. THE TOP FEW INCHES OFSEDIMENT SHOULD BE STOCKPILED SO THAT IT CAN BE REPLACED OVERTHE SURFACE OF THE WETLAND AFTER THE COMPLETION OF SEDIMENTREMOVAL TO RE-ESTABLISH THE VEGETATIVE COVER USING ITS OWNSEED BANK. ACCUMULATED SEDIMENT SHOULD BE REMOVED FROMAROUND INLET AND OUTLET STRUCTURES. NOTES1. THE WETLAND MUST BE STABILIZED WITHIN 14 DAYS OF CONSTRUCTION. CONSTRUCTION SHALLBE SEQUENCED SO THAT VEGETATION CAN BE PLANTED AND THE WETLAND BROUGHT ONLINEWITHIN 14 DAYS. PLANTS MAY NEED TO BE WATERED DURING THIS TIME IF THE DEVICE IS NOTBROUGHT ONLINE THE SAME DAY. STABILIZATION MAY BE IN THE FORM OF FINAL VEGETATIONPLANTINGS OR A TEMPORARY MEANS UNTIL THE VEGETATION BECOMES ESTABLISHED. IF USINGA TEMPORARY MEANS, CONTRACTOR SHALL PROVIDE A WET HYDROSEED MIX. CONTRACTORSHALL SCARIFY THE SOIL TO A HALF-INCH PRIOR TO HYDROSEEDING.2. INLET AND OUTLET CHANNELS SHALL BE PROTECTED FROM SCOUR THAT MAY OCCUR DURINGPERIODS OF HIGH FLOW. STANDARD EROSION CONTROL MEASURES SHOULD BE USED.3. THE STORMWATER WETLAND SHOULD BE STAKED AT THE ONSET OF THE PLANTING SEASON.WATER DEPTHS IN THE WETLAND SHOULD BE MEASURED TO CONFIRM THE ORIGINAL PLANTINGZONES. AT THIS TIME, IT MAY BE NECESSARY TO MODIFY THE PLANTING PLAN TO REFLECTALTERED DEPTHS OR THE AVAILABILITY OF WETLAND PLANT STOCK. CONTRACTOR SHALLCOORDINATE PLANTINGS, PLANTING ZONES AND WATER DEPTHS WITH THE ENGINEER.SURVEYED PLANTING ZONES SHOULD BE MARKED ON AN “AS-BUILT” OR RECORD DESIGN PLANAND LOCATED IN THE FIELD USING STAKES OR FLAGS.4. THE WETLAND DRAIN SHOULD BE FULLY OPENED FOR NO MORE THAN 3 DAYS PRIOR TO THEPLANTING DATE (WHICH SHOULD COINCIDE WITH THE DELIVERY DATE FOR THE WETLAND PLANTSTOCK) TO PRESERVE SOIL MOISTURE AND WORKABILITY.5. NURSERY STOCK SHALL BE TRANSPLANTED FROM LOCAL AQUATIC PLANT NURSERIES. THEOPTIMAL PERIOD FOR TRANSPLANTING EXTENDS FROM EARLY APRIL TO MID-JUNE SO THAT THEWETLAND PLANTS WILL HAVE A FULL GROWING SEASON TO BUILD THE ROOT RESERVES NEEDEDTO SURVIVE THE WINTER. HOWEVER, SOME SPECIES MAY BE PLANTED SUCCESSFULLY IN EARLYFALL. CONTRACTOR SHALL CONTACT NURSERY WELL IN ADVANCE OF CONSTRUCTION TOENSURE THAT THEY WILL HAVE THE DESIRED SPECIES AVAILABLE.6. POST-NURSERY CARE OF WETLAND PLANTS IS VERY IMPORTANT IN THE INTERVAL BETWEENDELIVERY OF THE PLANTS AND THEIR SUBSEQUENT INSTALLATION BECAUSE THEY ARE PRONETO DESICCATION. STOCK SHOULD BE FREQUENTLY WATERED AND SHADED.7. SHWT TO BE EVALUATED PRIOR TO CONSTRUCTION. IF SHWT IS WITHIN 6" OF PPE ELEVATION, ACLAY LINER WILL NOT BE REQUIRED. OTHERWISE, INSTALLATION OF A 6" CLAY LINER WILL BEREQUIRED. CLAY LINER SHALL HAVE A MINIMUM 15% PASSING THE #200 SIEVE AND A MAXPERMEABILITY OF 1 X 10-5 CM/SEC. ACCEPTABLE ALTERNATIVES INCLUDE A 30 MIL POLY-LINEROR A BENTONITE LINER.8. GRADES SHOWN REPRESENT FINISH GRADE ELEVATIONS. TO ACHIEVE FINISH GRADEELEVATIONS, INSTALL 4" OF TOPSOIL.9. PROVIDE PLANTS PER TABLE ON THIS SHEET. DAM STRUCTURE AND PERIMETER FILL SLOPESSHALL BE PLANTED WITH NON-CLUMPING TURF GRASS. TREES AND WOODY SHRUBS NOTALLOWED.10. CATTAILS SHALL NOT BE PLANTED IN WETLAND.OUTLET STRUCTURE NOTES & SPECIFICATIONS1. RCP OUTLET SHALL BE CLASS III RCP MEETING REQUIREMENTS OF ASTM C76. THE PIPE JOINTSSHALL BE MORTAR OR FLEXIBLE PLASTIC TYPE JOINT.2. THE MANHOLE OUTLET RISER SHALL MEET ASTM C-913. THE MANHOLE JOINTS SHALL BE ASTMC-443 RUBBER GASKET JOINTS. MANHOLE JOINTS SHALL BE SECURELY ANCHORED TO PREVENTSEPARATION. CONTRACTOR IS RESPONSIBLE FOR DESIGN OF THE MANHOLE SECTIONANCHORING SYSTEM.3. WATERTIGHT SEAL SHALL BE PROVIDED AT RISER/BARREL INTERFACE. PERVIOUS MATERIALSUCH AS SAND, GRAVEL, OR CRUSHED STONE SHALL NOT BE USED AS BACKFILL AROUND THEPIPE OR ANTI-SEEP COLLAR.
