18.45.075 Mitigation Sequencing <br />Applicants shall demonstrate that reasonable efforts have been examined with the <br />intent to avoid and minimize impacts to critical areas and critical area buffers. When an <br />alteration to a critical area or its required buffer is proposed, such alteration shall be <br />avoided, minimized or compensated for in the following order of preference: <br />1. Avoiding the impact altogether by not taking a certain action or parts of an <br />action; <br />2. Minimizing critical area or critical area buffer impacts by limiting the degree <br />or magnitude of the action and its implementation, by using appropriate technology, or by <br />taking affirmative steps to avoid or reduce impacts; <br />3. Rectifying the impact by repairing, rehabilitating or restoring the affected <br />environment; <br />4. Reducing or eliminating the impact over time by preservation and <br />maintenance operations during the life of the action; <br />5. Compensating for the impact by replacing, enhancing, or providing substitute <br />resources or environments; and/or <br />6. Monitoring the impact and taking appropriate corrective measures. <br />Section 27.
