RSSs are internally stabilized fill slopes, constructed of alternating layers of compacted soil and reinforcement. An RSS is different from an MSE wall or a conventional slope in that the slope has an inclination ranging from 1H:1V to 70° and will require a facing element. This Appendix governs the design of permanent and temporary RSSs. The design life of both permanent and temporary RSS is provided in Chapter 17. The procedures contained in this Appendix may also be used to

Follow the procedure outlined below during design. 1) Obtain from District Design plan sheets, elevation view plans of the slope, and cross sections of the slopes, both original grade (OG) and final grade (FG), at 25-feet spacing. 2) Obtain design constraints, such as plans showing right-of-way line, nearby culverts and utilities, feasibility or needs for
