Retaining Wall & Slope Drainage questions from Wildomar customers
- What builds up water pressure behind a retaining wall on a Wildomar slope?
- Shallow bedrock under finer soil. Borings at a Wildomar site logged clayey sand with lesser amounts of silty sands, sandy silts and sandy clays over Pauba Formation, which was encountered from the surface to depths of 51 and a half feet. Water moving through the upper soil slows sharply where it meets that formation, and behind a wall it has nowhere lateral to go unless drainage is built for it.
- How steep does terrain actually get in Wildomar?
- Unevenly steep. The 2019 Master Drainage Plan describes the terrain as flat to moderately hilly with some steeper mountainous areas on the east and west. Wildomar's flood hazard chapter assumes the same range, requiring contour intervals of two feet on ground of zero to two percent, four feet on three to nine percent, and ten feet on ten percent and above.
- Does a short retaining wall in Wildomar go through planning review?
- The development code exempts retaining walls less than 36 inches in height from planning review. That threshold governs planning entitlement, not drainage performance, so a short wall that needs no review can still be the thing holding back a saturated slope. Where a wall is tied into a fence above it, the code measures the combined height from the base of the wall as seen from the sidewalk or adjacent property.
- My Wildomar lot has a cut bank and a septic disposal field — does that limit slope drainage?
- Riverside County's onsite wastewater program sets the horizontal distance from a seepage pit to the top of a cut bank at five times the vertical height of the bank, or 25 feet, whichever is less. On a Wildomar lot where a slope was cut for the pad and the disposal field sits above or below it, that geometry constrains where slope drainage can be routed and where it can outlet.
