CONSTRUCTION OF PLANTER BOX MAY ONLY COMMENCE ONCE UPSTREAM AREAS ARE COMPLETELY STABILIZE. CONSULT COUNTY INSPECTOR BEFORE BEGINNING CONSTRUCTION.

IT IS CRITICAL TO KEEP SEIMENT OUT OF THE EXCAVATION. 3. CONSTRUCT THE SIES AN BOTTOM OF THE PLANTER BOXES WITH THE WATER PROOF MEMBRANE. 4.

6 1. REFER TO TABLE "FLOW THROUGH PLANTER BOX SUMMARY TABLE" FOR ELEVATIONS IORMATION FOR THE VARIOUS PLANTERS. 2. PLANTER MAY BE ABOVE OR ON GRAE. THE MINIMUM COVER FOR THE OUTLET PIPE (6" PVC PIPE) SHALL BE MINIMUM OF 6" UNER GRASS, 24" UNER CONCRETE OR ASPHALT. 3. PLANTER WALL AN BOTTOM MAY BE PRE-CAST CONCRETE, CAST IN PLACE CONCRETE OR ANOTHER MATERIALS TO EFINE THE PLATER LIMITS AN EFINE THE PLANTER LIMITS AN MAINTAIN THE WATERPROOF MEMBRANE. 4. THE OUTLET PIPE OF THE UNERRAIN SHALL HAVE POSITIVE SLOPE AN AYLIGHT ON THE SITE. MATERIAL FILTER MEIA COMPOSITION FILTER MEIA TESTING SPECIFICATION 1. CONSTRUCTION OF PLANTER BOX MAY ONLY COMMENCE ONCE UPSTREAM AREAS ARE COMPLETELY STABILIZE. CONSULT COUNTY INSPECTOR BEFORE BEGINNING CONSTRUCTION. THE SITE SHOUL BE STABILIZE TO THE POINT THAT EROSION AN SEIMENT CONTROLS ARE NO LONGER NECESSARY. 2. EXCAVATE THE PLANTER AREA TO THE PROPOSE EPTH. IT IS CRITICAL TO KEEP SEIMENT OUT OF THE EXCAVATION. 3. CONSTRUCT THE SIES AN BOTTOM OF THE PLANTER BOXES WITH THE WATER PROOF MEMBRANE. 4. FILL THE PLANTER WITH PLANTING SOIL MIX TO THE EPTH SHOWN ON THE ETAIL, AN SPECIFICATIONS. VERIFY THE SURFACE ELEVATIONS OF THE PALTER BE TO ENSURE THE AEQUATE POUNING OF WATER. THE ELEVATIONS OF PLACE IN LIFTS LESS THAN 6 INCHES AN LIGHTLY COMPACTE BY TAMPING BY HAN (MINIMAL COMPACTION REQUIRE). 5. PLANT VEGETATION SPECIFIE IN THE PLANTING PLAN AN SCHEULE. 6. CONSTRUCTION OF THE PALTER AREA SHOUL BE PERFORATE IN A TIMELY MANNER AN PREFERABLY URING A PERIO OF EXPECTE RY WEATHER. THE FACILITY SHOUL BE CONSTRUCTE AN FULLY STABILIZE AN OPERATION IN A MATTER OF A FEW AYS. NOTES FILTER MEIA TO CONTAIN: -85%-88% SAN -8%-12% SOIL FINES -3%-5% ORANGE MATTER IN THE FORM OF LEARF COMPOST THE VOLUME OF FILTER MEIA BASE ON 110% OF THE PLAN VOLUME TO ACCOUNT FOR SETTLING OR COMPACTION. P-INEX RANGE= OR BETWEEN 7 AN 21 MG/KG OF P IN THE SOIL MEIA. THE MEIA MUST BE PROCURE FROM APPROVE FILTER MEIA VENORS CECS GREATER THAN MULCH, IF UTILIZE FOR SURFACE COVER, SHALL BE WELL AGE, SHREE HARWOO BARK (WELL AGE MEANS IT HAS BEEN STORE OR STOCKPILE FOR 6-12 MONTHS). PARTICLES SHALL BE GREATER THAN 0.5 INCHES IN SIZE AN FREE FROM ANY HARMFUL CHEMICALS AN EXTRANEOUS MATERIAL. RIVER TONE, PEA GRAVEL, JUTE MATTING OR TURF MAY BE USE AS AN ALTERNATE SURFACE COVER. 2. THE STONE FOR THE UNERRAIN LAYER SHALL BE CLEAN, OUBLE WASHE VOT #57 STONE THAT IS FREE OF FINES (1 INCH MAXIMUM IAMETER STONE SIZE). 3. UNERRAIN PIPES SHALL BE A MIN. 4" IAMETER RIGI SR 35 PVC OR EQUIVALENT CORRUGATE HPE PIPE. COLLECTOR PIPE IN THE UNERRAIN LAYER SHALL BE PERFORATE WITH 3 8 INCH IAMETER PERFORATIONS LOCATE AT APPROXIMATELY THREE AN A QUARTER (3.25) INCHES ON CENTER AN FOUR PERFORATIONS PER ROW. PIPES SHOUL BE RUN AT A MINIMUM SLOPE OF 0.5% TO THE OUTLET. 4. WALLS OF THE PLANTING PIT SHALL BE UG SO THAT THEY ARE VERTICAL. THE PLANTING PIT SHALL BE EEP ENOUGH TO ALLOW 18" OF THE BALL TO BE ABOVE THE TING GRAE. LOOSE SOIL AT THE BOTTOM OF THE PIT SHALL BE TAMPE BY HAN. THE APPROPRIATE FERTILIZER SHALL BE PLACE IN THE BOTTOM OF THE PIT. 5. ROOT STOCK OF THE PLANT MATERIAL SHALL BE KEPT MOIST URING TRANSPORTATION FROM THE SOURCE TO THE JOB SITE AN UNTIL PLANTE. THE PLANT SHALL BE REMOVE FROM THE CONTAINER AN PLACE IN THE PLANTING PIT BY LIFTING AN CARRYING THE PLANT BY ITS BALL (NEVER LIFT BY BRANCHES OR TRUNK) 6. SET THE PLANT STRAIGHT AN IN THE CENTER OF THE PIT SO THAT 18" OF THE IAMETER OF THE ROOT BALL IS ABOVE THE FINAL GRAE. BACKFILL PLANTING PIT WITH TING SOIL. MAKE SURE PLANT REMAIN STRAIGHT URING BACKFILLING PROCEURE. NEVER COVER THE TOP OF THE BALL WITH SOIL. MOUN SOIL AROUN THE EXPOSE BALL ( 14") BECAUSE OF THE HIGH LEVELS OF NUTRIENTS IN RUNOFF TO BE TREATE, PLANTER PLANTS SHOUL NOT REQUIRE CHEMICAL FERTILIZERS. 7. THE PROPOSE FLOW THE PLANTER SHALL BE CHECKE FOR CORRECT OPERATION AN FLOW OF RUNOFF THROUGH THE FACILITY ONCE A MONTH FOR THE FIRST YEAR AN THEN BIANNUALLY THEREAFTER. SUPPLEMENTAL INSPECTIONS AFTER LARGE RAIN EVENTS SHALL BE MAE BY THE PROPERTY OWNER. THE FACILITY SHOUL BE CHECKE TO ENSURE THAT RAWOWN TIME OES NOT EXCEE 24 HOURS, THAT THE OUTFALL PIPES AN PERFORATE COLLECTOR PIPES ARE NOT CLOGGE, THAT THE PLANTINGS AREA VIABLE AN THAT THE SPLASH BLOCK IS IN PLACE AN PREVENTING OUGING THE SOIL MEIA. ANY FOUN PROBLEMS SHALL BE CORRECTE IMMEIATELY. The stormwater planter will be 26" to 42" above grade. THE STORMWATER MANAGEMENT FACILITIES SHOWN ON THIS PLAN SHALL BE CONSTRUCTE UNER THE SUPERVISION OF A LICENSE PROFESSIONAL ENGINEER, WHO WILL PROVIE TO ARLINGTON COUNTY ALL APPLICABLE CONSTRUCTION INSPECTIONS LOGS AN TEST OCUMENTATION FOR THE FACILITY AN PREPARE AN SUBMIT A WRITTEN STATEMENT CERTIFYING THE FACILITY WAS BUILT AS ESIGNE PER APPROVE PLAN.
