O CONTRACTOR SHALL CAST IN PLACE NEW CEMENT CONCRETE DEPRESSED GUTTER AND TRANSITIONAL CURB AS NEEDED. DIMENSIONS SHOWN ARE APPROXIMATE AND SHALL BE FIELD VERIFIED. NEW CURB AND GUTTER SHALL TRANSITION SMOOTHLY TO MATCH EXISTING GRADES AND FEATURES INCLUDING CURB, GUTTER, AND PAVEMENT. O OUTLET PIPE LOCATION VARIES, SEE DRAINAGE PLAN SHEETS. O CONTRACTOR TO BEND BIOFILTRATION TYPE A UNIT DOWEL BAR AS NEEDED TO INSTALL CAST IN PLACE DEPRESSED GUTTER AND THROAT OPENING. O INTERIOR FEATURES OF BIOFILTRATION TYPE A UNIT ARE TYPICALLY PROVIDED BY MANUFACTURER AND ARE SHOWN FOR REFERENCE ONLY. 6O STATION/OFFSET CONTROL POINTS FOR BIOFILTRATION TYPE A UNITS ARE TO THE CORNER OF EACH UNIT AT OUTER FACE OF PRECAST WALL. UNIT ALIGNMENT IS ORIENTED PARALLEL TO CURB LINE: LOCATIONS ARE APPROXIMATE, CONTRACTOR TO FIELD VERIFY.THROAT CLEARANCE SHALL BE 4" MIN AND 6" MAX. O7 SEE BIOFILTRATION TYPE A UNITS SCHEDULE FOR THROAT OPENING ELEVATION. TABLE ELEVATION IS APPROXIMATE, CONTRACTOR TO FIELD VERIFY. (8) THROAT CLEARANCE SHALL BE 4" MIN AND 6" MAX. GENERAL BIOFILTRATION TYPE A NOTES 1 1. BIOFILTRATION SYSTEM TYPE A WITHOUT PLANTS SHALL HAVE SOLID CONCRETE TOP SLAB AND ACCESS HATCHES MEETING LOADING REQUIREMENTS PER SCHEDULE TABLE BELOW. 2. BIOFILTRATION SYSTEM TYPE A UNIT TOP ELEVATION AND THROAT OPENING ELEVATIONS ARE APPROXIMATE. CONTRACTOR TO FIELD VERIFY UNIT ELEVATIONS AND SET UNIT ELEVATIONS TO ACHIEVE REQUIRED GRADES FROM EXISTING GUTTER. 3. IF THE BIOFILTRATION SYSTEM TYPE A UNIT IS STORED BEFORE INSTALLATION, THE TOP SLAB MUST BE PLACED ON THE BOX USING THE 2X4 WOOD PROVIDED, TO PREVENT ANY CONTAMINATION FROM THE SITE. ALL INTERNAL FITTINGS SUPPLIED (IF ANY), MUST BE LEFT IN PLACE AS PER THE DELIVERY. 4. THE UNIT SHALL BE PLACED ON A COMPACTED SUB -GRADE WITH A MINIMUM 6-INCH CSTC. THE UNIT IS TO BE PLACED SUCH THAT THE UNIT AND TOP SLAB MATCH THE GRADE OF THE CURB IN THE AREA OF THE UNIT. COMPACT UNDISTURBED SUB -GRADE MATERIALS TO 95% OF MAXIMUM DENSITY AT +1 TO 2% OF OPTIMUM MOISTURE. UNSUITABLE MATERIAL BELOW SUB -GRADE SHALL BE REPLACED TO THE ENGINEER'S APPROVAL. 5. OUTLET CONNECTIONS SHALL BE ALIGNED AND SEALED TO MEET THE APPROVED DRAWINGS WITH MODIFICATIONS NECESSARY TO MEET SITE CONDITIONS AND CITY STANDARDS. 6. ONCE THE UNIT IS SET, THE INTERNAL WOODEN FORMS AND PROTECTIVE MESH COVER MUST BE LEFT INTACT. REMOVE ONLY THE TEMPORARY WOODEN SHIPPING BLOCKS BETWEEN THE BOX AND THE TOP SLAB. THE TOP LID SHOULD BE SEALED ONTO THE BOX SECTION BEFORE BACKFILLING, USING A NON -SHRINK GROUT, BUTYL RUBBER OR SIMILAR WATERPROOF SEAL. THE BOARDS ON TOP OF THE LID AND BOARDS SEALED IN THE UNIT'S THROAT MUST NOT BE REMOVED. THE SUPPLIER (AMERICAST OR ITS AUTHORIZED DEALER) WILL REMOVE THESE SECTIONS AT THE TIME OF ACTIVATION. BACKFILLING SHOULD BE PERFORMED IN A CAREFUL MANNER, BRINGING THE APPROPRIATE FILL MATERIAL UP IN 6" LIFTS ON ALL SIDES. PRECAST SECTIONS SHALL BE SET IN A MANNER THAT WILL RESULT IN A WATERTIGHT JOINT. IN ALL INSTANCES, INSTALLATION OF BIOFILTRATION UNIT SHALL CONFORM TO ASTM SPECIFICATION C891 "STANDARD PRACTICE FOR INSTALLATION OF UNDERGROUND PRECAST UTILITY STRUCTURES", UNLESS DIRECTED OTHERWISE IN CONTRACT DOCUMENTS. 7. THE CONTRACTOR IS RESPONSIBLE FOR INLET PROTECTION/SEDIMENT CONTROL AND CLEANING AROUND EACH BIOFILTRATION SYSTEM TYPE A UNIT. 8. ACTIVATION OF THE BIOFILTRATION SYSTEM TYPE A UNIT IS PERFORMED ONLY BY THE SUPPLIER. CONTRACTOR IS RESPONSIBLE FOR BIOFILTRATION TYPE A INLET PROTECTION AND SUBSEQUENT CLEAN OUT COST. THIS PROCESS CANNOT COMMENCE UNTIL THE AREA TRIBUTARY TO THE UNIT IS FULLY STABILIZED AND CLEANED (FULL LANDSCAPING, GRASS COVER, FINAL PAVING AND STREET SWEEPING COMPLETED), NEGATING THE CHANCE OF CONSTRUCTION MATERIALS CONTAMINATING THE BIOFILTRATION SYSTEM TYPE A SYSTEM. CARE SHALL BE TAKEN DURING CONSTRUCTION NOT TO DAMAGE THE PROTECTIVE THROAT AND TOP PLATES. 9. BIOFILTRATION SYSTEM TYPE A SHALL CONSIST OF PRE -CAST VAULT WITH BIOFILTRATION MEDIA, OUTLET CHAMBER AND AN INTERNAL FLOW BYPASS SYSTEM. THE TREATMENT SHALL BE IN ACCORDANCE WITH DESIGN DATA AND INFORMATION CONTAINED IN THIS DRAWING AND THE CONTRACT DOCUMENTS. CONTRACTOR TO CONFIRM TREATMENT SYSTEM MEETS REQUIREMENTS OF THE PROJECT. 10. BIOFILTRATION SYSTEM TYPE A SHALL HAVE GENERAL USE LEVEL DESIGNATION (GULD) AND CERTIFICATION FROM THE WASHINGTON STATE DEPARTMENT OF ECOLOGY FOR BASIC AND METALS TREATMENT. 11. MANUFACTURER TO PROVIDE ALL MATERIALS UNLESS NOTED OTHERWISE. 12. FOR FABRICATION DRAWINGS WITH DETAILED STRUCTURE DIMENSIONS, WEIGHTS, AND ACCESSORIES, CONTACT MANUFACTURER.
