GENERAL RETAINING WALL NOTES:
1. INTERNATIONAL BUILDING CODE (IBC) 2018
STANDARDS SHALL BE DEEMED APPLICABLE AND USED
IN DESIGN ANALYSIS WITH IMPERIAL SYSTEM WEIGHT
AND MEASURE UNITS UNLESS OTHERWISE SPECIFIED.
2. REFERENCES USED IN RETAINING WALL DESIGN
INCLUDES ITERATIONS OF APPROVED DESIGN MANUALS
BY THE NATIONAL CONCRETE MASONRY ASSOCIATION
(NMCA).
3. RETAINING WALL BLOCKS SELECTED FOR DESIGN ARE
ASSUMED TO BE UNIFORM IN SIZE AND CONTAIN
UNIFORM BATTER FOR THE FULL RETAINED HEIGHT
UNLESS OTHERWISE SPECIFIED. ANY NOTABLE
DEFECTS IN SELECTED BLOCKS SHALL BE DISCARDED
IMMEDIATELY.
4. UNLESS OTHERWISE SPECIFIED, DESIGN ANALYSIS
ASSUMES COULOMB'S EARTH PRESSURE THEORY FOR
THE FAILURE PLANE ANGLE AND EARTH PRESSURES.
5. GEOTECHNICAL REPORTS ARE SPECIFIC TO EACH
PROJECT SITE AND SHALL BE USED FOR THE
RECOMMENDATION OF APPROPRIATE BACKFILL
MATERIAL, COMPACTION REQUIREMENTS, BEARING
PRESSURES, AND OTHER DESIGN RECOMMENDATIONS
NOTED WITHIN THE REPORT.
6. UNLESS OTHERWISE NOTED, CAP BLOCKS ARE
ASSUMED FOR DESIGN ANALYSIS AND CALCULATED IN
DESIGN LOADS AS NECESSARY.
7. GEOGRID VALUES SHOWN ARE OBTAINED FROM
INTERNATIONAL CODE COUNCIL EVALUATION SERVICE
OR PROVIDED BY VENDOR. IT IS RECOMMENDED THAT
GEOGRID LONG-TERM DESIGN STRENGTH (LTDS) AND
PEAK CONNECTION VALUES BE VERIFIED BY VENDORS
PRIOR TO CONSTRUCTION OF RETAINING WALLS.
8. GEOGRID SHALL BE EQUAL IN LENGTH, CONTAIN
EQUAL VERTICAL SEPARATION BETWEEN BLOCKS, AND
PULLED TIGHT HORIZONTALLY ACROSS COMPACTED
BACKFILL UNLESS OTHERWISE SPECIFIED.
9. THE UNIT WEIGHT OF BLOCK AND CELL FILL IS
ASSUMED TO BE 120 PCF UNLESS OTHERWISE
SPECIFIED.

10. IN GENERAL, CONSTRUCTION PROCEDURES SHALL
FOLLOW THE MOST RESTRICTIVE SPECIFICATIONS NOTED
BY THE GEOTECHNICAL ENGINEER, ENGINEER OF
RECORD, VENDOR, OR PROJECT DESIGN SPECIFICS.
11. THESE PLANS DO NOT GUARANTEE THE EXISTENCE,
NON-EXISTENCE OR LOCATION OF UTILITIES.
CONTRACTOR SHALL VERIFY THE EXISTENCE AND
LOCATION OR THE NON-EXISTENCE OF UTILITIES. AT
LEAST 48 HOURS PRIOR TO ANY EXCAVATION OR
CONSTRUCTION, CONTRACTOR SHALL NOTIFY MISS
UTILITY (1-800-552-7001) AND/OR THE RESPECTIVE
UTILITY COMPANIES FOR GAS, WATER, SEWER, POWER,
PHONE AND CABLE. CONTRACTOR SHALL TIMELY
ARRANGE TO HAVE THE VARIOUS UTILITIES LOCATED,
AND TO HAVE THEM REMOVED OR RELOCATED, OR TO
DETERMINE THE METHOD OF PROTECTION ACCEPTABLE
TO THE RESPECTIVE OWNER, IF THE METHOD OF
PROTECTION IS NOT OTHERWISE SPECIFIED.
12. IN GENERAL, ANY MAJOR NECESSARY FIELD
ADJUSTMENTS OF BLOCK ALIGNMENT AND/OR
PLACEMENT SHALL BE REVIEWED AND APPROVED BY
THE ENGINEER OF RECORD PRIOR TO CONSTRUCTION
OF SUCH ADJUSTMENTS.
13. IN GENERAL, ACTIVE AND AT -REST LATERAL EARTH
PRESSURE CONDITIONS ARE ASSUMED FOR RETAINING
WALL ANALYSIS UNLESS OTHERWISE SPECIFIED.
14. DRAINAGE SYSTEMS FOR RETAINING WALLS ARE
ASSUMED TO REMAIN IN A STATE OF CONSTANT
FUNCTIONING TO PREVENT HYDROSTATIC BUILDUP AND
LATERAL STRESSES IN ADDITION TO THOSE PRESSURES
SPECIFIED IN DESIGN. CONTRACTOR SHALL CONSTRUCT
THE DRAINAGE SYSTEM PER DESIGN AND VERIFY
FUNCTIONALITY IMMEDIATELY FOLLOWING INSTALLATION.
15. IN GENERAL, RETAINING WALL BACKFILL SHALL EXTEND
TO A MINIMUM OF 12" BEHIND THE RETAINED WALL
HEIGHT FROM THE BACK OF WALL.
16. RETAINING WALL BACKFILL SHALL BE PLACED IN 6" TO
8" LIFTS AND COMPACTED TO A MINIMUM DENSITY OF
105% OF THE MAXIMUM STANDARD PROCTOR DENSITY
AND FALL WITHIN 2-3% OF OPTIMAL MOISTURE
CONTENT.
RETAINING WALL DESIGN PLAN
FOR WALLS #1 & #2
BELVEDERE PHASE 5A
ALBEMARLE COUNTY, VIRGINIA
17. RETAINING WALL DESIGN IS BASED ON SAFETY
FACTORS ESTABLISHED BY THE NATIONAL CONCRETE
MASONRY ASSOCIATION (NMCA) FOR THE ANALYSIS OF
SLIDING, OVERTURNING, AND AN ALLOWABLE SOIL
BEARING CAPACITY. ULTIMATE BEARING CAPACITY IS
ASSUMED FOR DESIGN ANALYSIS UNLESS OTHERWISE
NOTED.
18. IN GENERAL, RETAINING WALL BACKFILL SHALL
CONSIST OF CLEAN VDOT #57 STONE FREE OF DEBRIS
AND EXCESSIVE SEDIMENT, OR AN APPROVED EQUAL
BY THE GEOTECHNICAL ENGINEER OR ENGINEER OF
RECORD UNLESS OTHERWISE SPECIFIED. BACKFILL
MATERIAL SHALL BE PLACED IN THE BLOCK CELL
VOIDS TO ENSURE UNITY AND OVERALL STRUCTURAL
INTEGRITY OF THE WALL.
19. IN GENERAL, IT IS RECOMMENDED THAT VEGETATIVE
SPECIES NEAR A RETAINING WALL BE PLANTED AT A
DISTANCE OF ITS MATURE CANOPY SIZE PLUS AN
ADDITIONAL 18 INCHES AWAY FROM THE WALL.
20. IN GENERAL, VEGETATIVE SPECIES PLANTED NEAR A
RETAINING WALL SHALL CONSIST OF A SHALLOW
TAPROOT WITH NON -AGGRESSIVE, NON-INVASIVE ROOT
SYSTEMS.
21. IN GENERAL, IT IS RECOMMENDED THAT VEGETATIVE
SPECIES PLANTED NEAR A RETAINING WALL BE
INSPECTED ANNUALLY TO DETERMINE ANY EXISTING OR
POTENTIAL THREATS TO THE STRUCTURAL INTEGRITY OF
THE RETAINING WALL.
22. IN GENERAL, ME RETAINING WALL INSPECTION THAT
PRODUCES A NOTABLE COMPROMISE TO ITS
STRUCTURAL INTEGRITY, THAT POTENTIALLY ENDANGERS
SAFETY, LIFE, OR PROPERTY, SHALL BE REPORTED TO
THE ENGINEER OF RECORD OR COUNTY ENGINEER
IMMEDIATELY.
23. IN GENERAL, IF A FULL GEOTECHNICAL REPORT IS NOT
AVAILABLE FOR A SPECIFIC JOB SITE, TYPICAL LOCAL
SOIL PARAMETERS WILL BE ASSUMED FOR DESIGN. THE
GEOTECHNICAL ENGINEER SHALL VERIFY APPROPRIATE
AND REASONABLE SOIL ASSUMPTIONS PRIOR TO WALL
CONSTRUCTION.
