A city EIR for a hillside site in north Lake Elsinore maps it as Cieneba rocky sandy loam, 15 to 50 percent slopes. The NRCS series description puts weathered bedrock 4 to 20 inches down and calls permeability moderately rapid in the soil and much slower in that bedrock. City code requires every slope over three feet in height to carry irrigation and permanent planting.
If the wall is dry but the ground behind the house stays wet, see French drain installation in Lake Elsinore.

Retaining Wall & Slope Drainage questions from Lake Elsinore customers
- What builds up pressure behind a retaining wall on a Lake Elsinore hillside lot?
- The granitic hillsides here map as Cieneba — a city EIR for a north Lake Elsinore hillside site identifies Cieneba rocky sandy loam at 15 to 50 percent slopes, with Hanford coarse sandy loam on the flat below. The NRCS series description puts the paralithic contact 4 to 20 inches down and describes permeability as moderately rapid in the soil but much slower in the weathered bedrock. Water moving fast through shallow soil slows at that contact.
- How steep are the hillside neighborhoods in Lake Elsinore?
- The General Plan's Country Club Heights chapter describes a district of steep hillsides where many lots carry slopes greater than 25 percent, on parcels ranging from 171 square feet to 6.5 acres. Its roadway network runs from dirt roads to narrow one-way paved roads, much of it under 20 feet wide with no shoulders where grades exceed 10 percent. The chapter names erosion among the resulting issues.
- Do Lake Elsinore's own rules put water behind my slope year-round?
- The city's grading standards require slopes exceeding three feet in height to be provided with irrigation systems and permanent planting chosen from a hillside plant list, installed before final inspection and before occupancy. That is an ongoing applied-water source on the slope, in a place where the NOAA normal for August rainfall is 0.06 inch. Slope drainage behind a wall is not only a storm-season question here.
- What did the 2018 Holy Fire change about hillside runoff above Lake Elsinore?
- Riverside County Flood Control's post-fire monitoring report records that the Holy Fire burned approximately 23,000 acres of the Cleveland National Forest in August 2018, with 14 percent of the burned area at high and 71 percent at moderate soil burn severity. The report notes that wildfires create the potential for high debris flows in watersheds with steep slopes and moderate-to-high burn severity, and the District monitored the McVicker Debris Basin for runoff discharging downstream to Lake Elsinore.
