Standard CM U Block Wall Detail The purpose of this Information Bulletin is to assist owners and builders who may choose to erect simple freestanding concrete masonry unit (CM U) block walls using the Department's standard detail. This Information Bulletin provides general requirements and specifications for the construc- tion of standard CM U block walls of various height, thickness or footing configurations. These walls are designed for the average condition and may not be suitable in all cases. Where the proposed wall construction is located on a site with slope steeper than 10%, with adverse soil conditions (e.g., expansive soil, liquefaction, flood hazard, etc.) or deviates from this Information Bulletin, a registered design professional licensed in the State of California should be consulted. TO DETERMINE HEIGHT FOR BUILDING CODE PURPOSES, "H" IS MEASURED FROM TOP OF FOOTING TO TOP OF WALL CAP. TO DETERMINE HEIGHT FOR ZONING CODE PURPOSES, SEE GENERAL ZONING REQUIREMENTS.

For lots that slope more than 5'-0" from front to rear, contact a Plan- ning staff at the Development Services Center to help establish the fence height. A 6'-0" corner cutoff may be required for fencing adjacent to driveways and sidewalks that obstruct visibility. 1 of 2 Standard CM U Block Wall Detail WALL HEIGHT T' TYPE FOUNDATION "T" TYPE FOUNDATION "I" TYPE FOUNDATION VERTICAL REBAR HORIZ.

Foundation must be poured against undisturbed soil with no appreciable slope of sidewalls. All horizontal and vertical reinforcements shall maintain a min. 3" clearance from the bot- tom and sides of the trench. Horizontal bond beam reinforcement is required to be located in the 2nd course from the top of the wall. Prefabricated joint reinforcement in each two top mortar joints consist- ing of two No. 9 gage galvanized wires with No. 9 gage steel welded cross wires spaced a max. 16" o.c. may be substituted for the horizontal bond beam reinforcement in the top of walls 5'-6" or less in heights. All wires shall be thoroughly embedded in the bed joint mortar and lapped a min. of 12". Units shall be staggered (common bond are not permitted) and may be partially grouted with grout confined to those cells that have horizontal and vertical reinforcing steel. SPECIFICATIONS: Min. 2,500 psi strength in 28 days. Mix for concrete footing to be 1 part ce- Concrete: ment to 2-1/2 parts sand to 3-1/2 parts gravel with a max. of 7-1/2 gallons of water per sack of cement. Block: Grade "N" ASTM C 90-03. Nominal width of units shall be a min. 6". Reinforcement: Deformed steel bar conforming to ASTM A-615 Grade 40 or Grade 60. Mortar (Type "S") Mix to be 1 part cement to 1 /2 part lime to 3 parts damp loose sand. Mix to be 1 part cement to 3 parts sand to max. 1 /10 part lime. Sufficient water Grout: should be added to produce consistency for pouring without segregation of the constituents. May contain 2 parts pea gravel (max. size 3/8"). INSPECTIONS: Foundation Insp.: When trench is ready for concrete and all steel reinforcements are tied in place. Pre -Grout Insp.: When first horizontal bar and all vertical bars are in place, but not grouted! Final Insp.: After wall is grouted and cap is installed COMMON PROPERTY FENCE WALL: Where a common property fence wall is requested, a completed and signed "Common Property Wall Line Agreement and Maintenance" form by all of the common property owners is required prior to ap- proval of the 1 st inspection (i.e., foundation inspection). 2of2 IN nnui EXCEPT 1il t10 BUILD THE HDUI 71'IFV I41i: 14 VAIN 44AT &UIID IT genpy I M ter Ib�� RIUPAU AVE, so"[ 110 CORONA, C A 92819 Date: 1eL �Hfl560-1385 eogioeeriogsoluliaos.iofo@gmail.com Drawings and written material appearing herein constitute original and unpublished work of IS Egineering Solutions and may not be duplicated used or disclosed without written consent of IS Engineering Solutions. eWESS/ONg1 � c r_- George F EndrawesOf w m C91685 0 PROJECT: E111010.11-5101 0 GARAGE CONVERSION TO ADUs PROJECT ADDRESS: 1313 N SPURGEON ST.
