Full Breakdown
Lake Elsinore Municipal Code § 15.72.050 sets a tiered height scheme for retaining walls built under the City's grading standards. One upslope retaining wall not exceeding six feet in height may be used, while a downslope retaining wall is capped at three and one-half feet. On lots sloping with the street, and other configurations not otherwise addressed, one retaining wall not exceeding three feet may be used on each side of the lot, and the same three-foot limit applies to retaining walls placed adjacent to driveways on each side of the lot.
Any retaining wall exceeding two and one-half feet in height triggers a safety requirement: it must have a protective fence or guard rail at least 36 inches tall, and the combined height of the retaining wall plus that protective fence or guard rail is still subject to the ordinance's height limitation for the applicable yard location, so a tall wall cannot be used to circumvent the underlying fence-height rules for front, side or rear yards. The City Engineer or design review may approve an alternate retaining wall system with different dimensions and locations if practical site considerations justify it and the alternative will not create an adverse visual or environmental impact.
These retaining wall standards sit within the broader grading chapter, which also caps hillside cut and fill slopes at 30 feet vertical height and requires slopes over three feet to be irrigated and planted, so retaining wall design is reviewed alongside a project's overall grading plan by the City Engineer or minor design review under Sections 15.72.020 and 15.72.030.
Violations & Fines
Building a retaining wall that exceeds the height allowed for its slope position, or exceeding two and one-half feet without the required 36-inch protective fence or guard rail, is a violation of the Lake Elsinore Municipal Code grading standards, enforced under § 1.16.010 as a misdemeanor with a fine up to $1,000 and up to six months in jail, or as an infraction with fines from $100 to $500 for repeat violations within a year.
