3. Buffer width averaging is not utilized; and either 1. Structures, public roads, or other substantial improvements separate the subject upland property from the wetland and due to their height or width, prevent or impair the delivery of buffer functions delivered to the wetland;or 5. The wetland scores three or four points for wildlife habitat. CI Required General Mitigation Measures. Implementation of the following general mitigation measures allow use of the reduced wetland buffers listed in Table 37.3. a. Direct lights away from the wetland. b. Locate activity that generates noise away from the wetland. c. Route all new, untreated runoff away from the wetland while ensuring wetland is not dewatered. d. Establish covenants limiting use of pesticides within 150 feet of the wetland. e. Apply integrated pest management. f. Retrofit stormwater detention and treatment for roads and existing adjacent development. g. Prevent channelized flow from lawns that directly enters the buffer. h. Infiltrate or treat, detain,and disperse into buffer new runoff from impervious surfaces and new lawns. i. Use privacy fencing; plant dense vegetation to delineated buffer edge and discourage disturbance using vegetation appropriate for the ecoregion; place the wetland and its buffer in a separate tract. j. Use best management practices to control dust. D_ —Where wetland functions have been improved due to voluntary implementation of an approved stewardship, restoration and/or enhancement plan that is not associated with required mitigation or enforcement,the standard wetland buffer width shall be determined based on the previously established wetland category and habitat score as documented in the approved stewardship and enhancement plan. 19.37.1104 20 Wetland Alteration Thresholds and Compensation . of the acreage or functions and values of all wetlands regulated by this chapter.The long term goal is a methods of wetland impact mitigation in order of preference: 1. Avoid impact altogether by not taking a certain action or parts of an action; 2. Minimize impact by limiting the degree or magnitude of the action and its implementation by using appropriate technology, or by taking affirmative steps to avoid or reduce impact; 3. Rectify the impact by repairing, rehabilitating or restoring the affected critical areas; 1. Reduce or eliminate the impact over time by prevention and maintenance operations during the life of the actions; 5. Compensate for the impact by replacing, enhancing, or providing substitute wetland areas and environments; 6. Monitor the impact and take appropriate corrective measures. Where impacts cannot be avoided, the applicant shall seek to implement other appropriate mitigation actions. Planning Commission Resolution 19-04 Page 37 Critical Areas March 19, 2019
