Notes:

1. This design meets or exceeds the minimum factors of safety required by Risi Stone Systems based on the design

parameters listed above. The analysis was performed as outlined in the National Concrete Masonry Association

Design Manual for Segmental Retaining Walls, Third Edition. This is a typical, non site-specific Design.

2. No analysis of global stability, total or differential settlement, or seismic effects has been performed.

3. This design is only provided to illustrate the general arrangement of the SRW structure for preliminary costing and

feasibility purposes only. This drawing is not for construction. A qualified Engineer must be retained to provide the

4. Structures such as handrails, guardrails, fences, terraces, and site conditions such as water applications, drainage

and soil conditions, additional live and dead loads, etc., have significant effects on the wall design and have not been

taken into account in this typical section. When accounted for in the Final Design, other conditions and elements may

result in additional design measures (geogrid, drainage, etc) and cost.

Final Design prior to construction.
