LOW PLASTICITY CLAYEY SAND (SC), SILT OR CLAY (ML-CL) CAN BE USED
SUBJECT TO APPROVAL BY THE GEOTECHNICAL ENGINEER.
MAXIMUM PARTICLE SHALL BE LIMITED TO 4INCHES IN DIAMETER.
THE FINE FRACTION (MINUS NO. 40 SIEVE) SHALL HAVE A MAXIMUM
LIQUID LIMIT (LL) OF 40 AND A MAXIMUM PLASTICITY INDEX (PI)
OF 20. THE BACKFILL SHALL BE FREE OF DEBRIS AND ORGANIC MATTER.
HIGHLY EXPANSIVE SOILS (MH-CH) SHALL NOT BE USED IN THE
REINFORCED FILL ZONE.
15.0 REINFORCED FILL SHALL BE PLACED IN 8-INCH LIFTS AND
COMPACTED TO A MINIMUM OF 95% OF MAXIMUM STANDARD
PROCTOR DENSITY (A5TM D-698) AND WITHIN + 3 PERCENTAGE
POINTS OF OPTIMUM MOISTURE CONTENT. COMPACTION TESTS SHALL
BE PERFORMED AS THE WALL IS INSTALLED. COMPACTION WITHIN
3 FEET OF THE WALL SHALL BE LIMITED TO HAND -OPERATED EQUIPMENT.
DESIGN PARAMETERS:
1 BUILDING CODES: 2015 VIRGINIA UNIFORM STATEWIDE BUILDING CODE (USBC)
AND 2015 INTERNATIONAL BUILDING CODE (IBC).
2 THE WALL PROFILES ARE BASED ON THE GRADING & DRAINAGE PLAN,
SHEET NO. C8 AND SHEET NO.9, DATED OCTOBER 1, 2021 (REV. 12/28/21),
PREPARED BY COLLINS ENGINEERING.
3 WALL DETAILS SHOWN ON THIS PLAN ARE FOR ANCHOR DIAMOND PRO
SEGMENTAL RETAINING WALL (SRW) UNITS MEETING THE NATIONAL
CONCRETE MASONRY ASSOCIATION (NCMA) CRITERIA FOR SRW WALL SYSTEMS.
4 ENGINEERING ANALYSIS BASED ON USE OF STRATAGRID 5GU60 GEOGRID.
OTHER COMPATIBLE GEOGRIDS MAY BE SUBSTITUTED WITH THE APPROVAL
OF THE WALL DESIGN ENGINEER.

NO.57 STONE. COMPACTION TESTS CAN BE WAIVED
WHERE NO.57 STONE IS USED AS REINFORCED FILL.
17.0 CONTRACTOR SHALL SLOPE SITE GRADES TO DIRECT SURFACE
RUNOFF AWAY FROM WALL AT END OF EACH DAY TO AVOID
WATER DAMAGING THE WALL WHILE UNDER CONSTRUCTION.
18.0 ANY SURFACE DRAINAGE FEATURES, FINISH GRADING, PAVEMENT,
OR TURF SHALL BE INSTALLED IMMEDIATELY AFTER THE WALL IS COMPLETED.
19.0 IF SITE AND SOIL CONDITIONS, WALL GEOMETRY, OR WALL
