USGS elevation samples across Menifee run from about 1,424 feet in Sun City to about 1,589 feet in Quail Valley.

Retaining Wall & Slope Drainage questions from Menifee customers
- What does Menifee require on a graded slope above or behind a wall?
- Menifee's grading code sets terraces at vertical intervals no greater than thirty feet on cut or fill slopes, with terrace drains at a minimum five percent gradient, paved in concrete not less than three inches thick. It also calls for concrete interceptor drains along the tops of cut slopes where tributary drainage runs toward the slope, at a minimum two percent gradient.
- Is subsurface drainage behind a slope or wall optional in Menifee?
- The city's grading regulations state that cut and fill slopes shall be provided with subsurface drainage as necessary for stability and as recommended by the soil engineer. That makes a geotechnical recommendation the controlling document rather than a standard detail. On a pad-and-slope lot the wall and the slope above it function as one drainage system.
- How much relief is there really in Menifee?
- It varies sharply by neighborhood. USGS 3DEP elevation samples return about 1,424 feet in Sun City and about 1,441 feet near the central valley floor, against roughly 1,474, 1,535, 1,553 and 1,589 feet at sampled points in Quail Valley. Slope and wall drainage is correspondingly a western hillside concern more than a valley-floor one.
- What tends to fail first behind a retaining wall on a Menifee slope?
- Water that was never intercepted above it. The city's code runs top-down: interceptor drains at the crest of cut slopes, terrace drains at intervals down the face, subsurface drainage where the soil engineer calls for it, and a prohibition on runoff sheeting over slopes steeper than five to one. A wall at the toe is the last element in that sequence, not a replacement for it.
