(1) The mitigation plan shall specifically address how the activity maintains or reduces the preexisting level of risk to the site and adjacent properties on a long-term basis (equal to or exceeding the projected lifespan of the activity or occupation). Mitigation techniques providing long-term hazard reduction are those that do not require periodic maintenance or other actions to maintain their function.
(2) Mitigation may be required to avoid any increase in risk above the preexisting conditions following abandonment of the activity.
(3) Any required restoration shall meet the long-term hazard reduction standards. In the case of restoration, “long-term” shall be defined as the equivalent of natural function. [Ord. 4525 § 1, 2021; Ord. 3911, 2009; Code 1970 § 28.32.080. Formerly 28.32.080.]
