Article III — GRADING ADJACENT TO PROPERTY LINES

This article applies to treatment of slopes within multilot developments, and to permit boundary slopes. (Prior code § 86200)

Cut and fill slopes adjacent to property line and at other approved locations shall not be steeper than one vertical to two (2) horizontal. (Prior code § 86201)

When two (2) or more lots are graded, and cut and fill slopes of steeper than ten percent (10%) occur adjacent to the property line between the lots, the top of the slope shall be located at the property line. (Prior code § 86202)

Where earth fill of twelve inches (12") or more is placed on property having a natural average slope of five percent (5%) or less, a retaining wall not to exceed five feet (5') above the original natural grade shall be placed adjacent to the property lines at locations where a grading permit boundary line abuts vacant property, or the rear yard area of adjacent properties when the slope of the finish grade exceeds ten percent (10%) within twenty feet (20') of the permit boundary line. (Prior code § 86203(A))

Where earth fill of twelve inches (12") or more is placed on property having a natural slope of five percent (5%) or less, or is abutting a street which has a slope of five percent (5%) or less, a retaining wall not to exceed thirty inches (30") in height shall be placed adjacent to the property line when the grading permit boundary abuts a side yard of adjacent properties, excepting the rear twenty five feet (25') thereof when the fill slope exceeds ten percent (10%) in any area within the side property line. The treatment of the rear twenty five feet (25') of a lot upon a permit boundary which abuts an adjacent side yard may comply with section 18.212.150 of this chapter. (Prior code § 86204(A))
