2. Minimising impacts 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 impacts; Due to the centralized locations of Wetland A and Wetland B and the constraints posed by the small property size (1.18 acres), no practical site design was identified that would result in less than the proposed impacts to onsite critical areas while achieving the applicant's housing development objectives on the 1.18-acre site. Internal access roads, fire access/turnarounds, and utilities will utilize the remainder of available space not already allocated for residential development. 3. Decting the impact by repairing rehabilitating or restoring the affected critical area; Not applicable. Repairing, rehabilitating, or restoring the affected portions of Wetland A and Wetland B and the associated buffer onsite is not possible, as the entire site is planned to accommodate the proposed development and no onsite wetland or buffer areas will remain after the proposed fill occurs. 4. Deducing or eliminating the impact over time by preservation or maintenance operations during the life of the actions; The proposed project requires the unavoidable, total fill of the onsite portions of Wetland A and Wetland B. Mitigation will be provided through the purchase of mitigation bank credits from the Keller Farm Mitigation Bank (-,'_FMB). As such, no preservation or maintenance operations are required in association with the proposed impacts S. Compensate for the impact by replacing enhancing or providing substitute wetland areas and environments; Onsite compensation is not a practicable as the entire site is planned to accommodate the proposed development. The necessary and unavoidable fill of onsite Wetland A (10,253 square feet onsite) and Wetland B (502 square feet)will be compensated through the purchase of mitigation bank credits from KFMB. 788 square feet of Wetland A exists offsite to the west and the north of the subject property. Although these areas are not proposed to be filled, they will in effect,become isolated and non-functioning following the fill of the onsite portion of Wetland A. Therefore, the project will consider these areas as being directly impacted for calculating total impacted wetland areas for mitigation. The proposed use of a mitigation bank will result in no net loss in ecological functions within the Cedar-Sammamish watershed. 6. Monitoring the impact and take appropriate corrective measures. No onsite monitoring will be required for the proposed project as no onsite, permittee- responsible mitigation actions are proposed; monitoring activities will be conducted by the Keller Farms Mitigation Bank. 1.1.3 Wetland Compensation The project proposes unavoidable direct impacts to Wetland A and Wetland B. Per EMC 19.37.120.B, wetland and buffer alterations are subject to the following requirements: 1345.0029—Benton Square 2 Soundview Consultants LLC Conceptual Mitigation Bank Use Plan April 1,2022
