INFILTRATION TRENCH GENERAL NOTES AND SPECIFICATIONS

THE INFILTRATION TRENCH SYSTEMS MAY NOT RECEIVE RUN-OFF UNTIL THE

ENTIRE CONTRIBUTING DRAINAGE AREA TO THE INFILTRATION SYSTEM HAS

RECEIVED FINAL STABILIZATION.

1. HEAVY EQUIPMENT AND TRAFFIC SHALL BE RESTRICTED FROM TRAVELING

OVER THE INFILTRATION TRENCH TO MINIMIZE COMPACTION OF THE SOIL.

2. EXCAVATE THE INFILTRATION TRENCH TO THE DESIGN DIMENSIONS.

EXCAVATED MATERIALS SHALL BE PLACED AWAY FROM THE TRENCH SIDES

TO ENHANCE TRENCH WALL STABILITY. LARGE TREE ROOTS MUST BE

TRIMMED FLUSH WITH THE TRENCH SIDES IN ORDER TO PREVENT FABRIC

PUNCTURING OR TEARING OF THE FILTER FABRIC DURING SUBSEQUENT

INSTALLATION PROCEDURES. THE SIDE WALLS OF THE TRENCH SHALL BE

ROUGHENED WHERE SHEARED AND SEALED BY HEAVY EQUIPMENT.

3. A CLASS “C” GEOTEXTILE OR BETTER SHALL INTERFACE BETWEEN THE

TRENCH SIDE WALLS AND BETWEEN THE STONE RESERVOIR AND GRAVEL

FILTER LAYERS. A PARTIAL LIST OF NON-WOVEN FILTER FABRICS THAT

MEET THE CLASS “C” CRITERIA IS CONTAINED BELOW. ANY ALTERNATIVE

FILTER FABRIC MUST BE APPROVED BY THE LOCAL AUTHORITY PRIOR TO

INSTALLATION.

MIRAFI 180-N

AMOCO 4552

WEBTEC N70

GEOLON N70

CARTHAGE FX-80S

THE WIDTH OF THE GEOTEXTILE MUST INCLUDE SUFFICIENT MATERIAL TO

CONFORM TO TRENCH PERIMETER IRREGULARITIES AND FOR A 6-INCH

MINIMUM TOP OVERLAP. THE FILTER FABRIC SHALL BE TUCKED UNDER THE

SAND LAYER ON THE BOTTOM OF THE INFILTRATION TRENCH FOR A

DISTANCE OF 6 TO 12 INCHES. STONES OR OTHER ANCHORING OBJECTS

SHOULD BE PLACED ON THE FABRIC AT THE EDGE OF THE TRENCH TO KEEP

THE TRENCH OPEN DURING WINDY PERIODS. WHEN OVERLAPS ARE

REQUIRED BETWEEN ROLLS, THE UPHILL ROLL SHOULD LAP A MINIMUM OF 2

FEET OVER THE DOWNHILL ROLL IN ORDER TO PROVIDE A SHINGLED

EFFECT.

4. A SAND LAYER SHALL BE PLACED ON THE BOTTOM OF THE INFILTRATION

TRENCH, AND SHALL BE COMPACTED USING PLATE COMPACTORS. THE

SAND FOR THE INFILTRATION TRENCH SHALL BE WASHED AND MEET

AASHTO STD. M-43, SIZE NO. 9 OR NO. 10. THE THICKNESS OF THE SAND

LAYER VARIES SEE SHEET C-135 FOR DEPTHS.

5. THE STONE AGGREGATE SHOULD BE PLACED IN LIFTS AND COMPACTED

USING PLATE COMPACTORS. A MAXIMUM LOOSE LIFT THICKNESS OF 12

INCHES IS RECOMMENDED. GRAVEL FILLING (ROUNDED BANK RUN GRAVEL

IS PREFERRED) FOR THE INFILTRATION TRENCH SHALL BE WASHED AND

MEET ONE OF THE FOLLOWING: AASHTO STD. M-43; SIZE NO. 2 OR NO. 3. 6.

6. FOLLOWING THE STONE AGGREGATE PLACEMENT, THE FILTER FABRIC

SHALL BE FOLDED OVER THE STONE AGGREGATE TO FORM A 6-INCH

MINIMUM LONGITUDINAL LAP. THE DESIRED FILL SOIL OR STONE

AGGREGATE SHALL BE PLACED OVER THE LAP AT SUFFICIENT INTERVALS

TO MAINTAIN THE LAP DURING SUBSEQUENT BACKFILLING.

7. CARE SHALL BE EXERCISED TO PREVENT NATURAL OR FILL SOILS FROM

INTERMIXING WITH THE STONE AGGREGATE. ALL CONTAMINATED STONE

AGGREGATE SHALL BE REMOVED AND REPLACED WITH UNCONTAMINATED

STONE AGGREGATE.

8. VOIDS CAN BE CREATED BETWEEN THE FABRIC AND THE EXCAVATION

SIDES AND SHALL BE AVOIDED. REMOVING BOULDERS OR OTHER

OBSTACLES FROM THE TRENCH WALLS IS ONE SOURCE OF SUCH VOIDS,

THEREFORE, NATURAL SOILS SHOULD BE PLACED IN THESE VOIDS AT THE

MOST CONVENIENT TIME DURING CONSTRUCTION TO ENSURE FABRIC

CONFORMITY TO THE EXCAVATION SIDES.

9. VERTICALLY EXCAVATED WALLS MAY BE DIFFICULT TO MAINTAIN IN AREAS

WHERE SOIL MOISTURE IS HIGH OR WHERE SOFT COHESIVE OR

COHESIONLESS SOILS ARE PREDOMINATE. THESE CONDITIONS MAY

REQUIRE LAYING BACK OF THE SIDE SLOPES TO MAINTAIN STABILITY.

10. THE OBSERVATION WELL IS TO CONSIST OF 6-INCH DIAMETER PVC

SCHEDULE 40 PIPE (ASTM STD. D 1784) WITH A CAP SET 6 INCHES ABOVE

GROUND LEVEL AND IS TO BE LOCATED NEAR THE LONGITUDINAL CENTER

OF THE INFILTRATION TRENCH. PREFERABLY THE OBSERVATION WELL WILL

NOT BE LOCATED IN VEHICULAR TRAFFIC AREAS. THE PIPE SHALL HAVE A

PLASTIC COLLAR WITH RIBS TO PREVENT ROTATION WHEN REMOVING CAP.

THE SCREW TOP LID SHALL BE A “PANELLA” TYPE CLEANOUT WITH A

LOCKING MECHANISM OR SPECIAL BOLT TO DISCOURAGE VANDALISM. A

PERFORATED (1/2 INCH DIAMETER HOLES) PVC SCHEDULE 40 PIPE SHALL BE

PROVIDED AND PLACED VERTICALLY WITHIN THE GRAVEL PORTION OF THE

INFILTRATION TRENCH AND A CAP PROVIDED AT THE BOTTOM OF THE PIPE.

THE BOTTOM OF THE CAP SHALL REST ON THE INFILTRATION TRENCH

BOTTOM.

11. IF A DISTRIBUTION STRUCTURE WITH A WET WELL IS USED, A 4-INCH PVC

DRAIN PIPE SHALL BE PROVIDED AT OPPOSITE ENDS OF THE INFILTRATION

TRENCH DISTRIBUTION STRUCTURE. TWO (2) CUBIC FEET OF POROUS

BACKFILL MEETING AASHTO STD. M-43 SIZE NO. 57 SHALL BE PROVIDED AT

EACH DRAIN.

12. IF A DISTRIBUTION STRUCTURE IS USED, THE MANHOLE COVER SHALL BE

BOLTED TO THE FRAME.

INFILTRATION BASINS NOTES AND SPECIFICATIONS

1. THE SEQUENCE OF VARIOUS PHASES OF BASIN CONSTRUCTION SHALL BE COORDINATED WITH THE

OVERALL PROJECT CONSTRUCTION SCHEDULE. THE PARTIALLY EXCAVATED BASIN, CANNOT SERVE AS A

SEDIMENTATION BASIN.

2. INITIAL BASIN EXCAVATION SHOULD BE CARRIED TO WITHIN 2 FEET OF THE FINAL ELEVATION OF THE

BASIN FLOOR. FINAL EXCAVATION TO THE FINISHED GRADE SHOULD BE DEFERRED UNTIL ALL

DISTURBED AREAS ON THE WATERSHED HAVE BEEN STABILIZED OR PROTECTED. THE FINAL PHASE

EXCAVATION SHOULD REMOVE ALL ACCUMULATED SEDIMENT. RELATIVELY LIGHT TRACKED EQUIPMENT

IS RECOMMENDED FOR THIS OPERATION TO AVOID COMPACTION OF THE BASIN FLOOR. AFTER THE

FINAL GRADING IS COMPLETED, THE BASIN SHOULD RETAIN A HIGHLY POROUS SURFACE TEXTURE.

3. INFILTRATION BASINS MAY BE LINED WITH A 6- TO 12-INCH LAYER OF FILTER MATERIAL SUCH AS COARSE

SAND (AASHTO STD. M-43, SIZES 9 OR 10) TO HELP PREVENT THE BUILDUP OF IMPERVIOUS DEPOSITS ON

THE SOIL SURFACE. THE FILTER LAYER CAN BE REPLACED OR CLEANED WHEN IT BECOMES CLOGGED.

WHEN A 6-INCH LAYER OF COARSE ORGANIC MATERIAL IS SPECIFIED FOR DISCING (SUCH AS HULLS, LEAVES, STEMS, ETC.) OR SPADING INTO THE BASIN FLOOR TO INCREASE THE PERMEABILITY OF THE

SOILS, THE BASIN FLOOR SHOULD BE SOAKED OR INUNDATED FOR A BRIEF PERIOD, THEN ALLOWED TO

DRY SUBSEQUENT TO THIS OPERATION. THIS INDUCES THE ORGANIC MATERIAL TO DECAY RAPIDLY, LOOSENING THE UPPER SOIL LAYER.

4. EROSION PROTECTION OF INFLOW POINTS TO THE BASIN SHALL ALSO BE PROVIDED.

5. THE BASIN SIDE SLOPES AND FLOOR SHALL BE STABILIZED WITH VEGETATION. SELECTION OF SUITABLE

VEGETATIVE MATERIALS AND APPLICATION OF REQUIRED LIME, FERTILIZER, ETC. SHALL BE DONE IN

ACCORDANCE WITH THE THE PERMANENT SEEDING REQUIREMENTS PROVIDED ON SHEETC-752, DETAIL

C4.

6. MOWING SHALL BE CONDUCTED AT LEAST TWICE A YEAR, ONCE IN JUNE AND AGAIN IN SEPTEMBER.
