Impact to such wetlands would therefore <br />result in a net loss of some functions no matter what kind of mitigation is provided. 2 Provides gains in a whole suite of functions both at the site and landscape scale. Rehabilitation actions often focus <br />on restoring environmental processes that have been disturbed or altered by previous ongoing human activity. 3 Actions which provide gains in only a few functions. Enhancement action often focuses on structural or superficial <br />improvements to a site and generally does not address larger scale environmental processes. 4 Compensatory mitigation for vernal pool impacts must be seasonally ponded wetland area(s). <br /> <br />8. Increased replacement ratios: The Administrator shall increase the wetland mitigation ratios <br />under the following circumstances: <br />a. Uncertainty exists as to the probable success of the proposed restoration or creation; <br />b. A significant period of time will elapse between impact and replication of wetland <br />functions; or <br />c. Proposed mitigation will result in a lower category wetland or reduced functions relative <br />to the wetland being impacted. <br />9. Alternative mitigation ratios: The Administrator may approve different mitigation ratios when <br />the applicant proposes a combination of wetland creation, restoration, rehabilitation, and/or <br />enhancement, provided that federal and state resource agencies approve the mitigation plan <br />and the plan achieves no net loss of wetland functions and values. <br /> <br />17B.05.020J Aquatic habitat conservation areas – designation and mapping. <br />1. Designation and classification: Aquatic habitat conservation areas include: <br />a. Those streams and lakes which meet the criteria for Type S, F, Np, and Ns waters, as <br />defined in the water type classifications in the forest practices rules in WAC 222-16-030. <br />Type S waters are synonymous with shorelines of the state. <br />b. Areas with which federally and/or state-listed endangered, threatened, or sensitive <br />aquatic species have a primary association; <br />c. State priority aquatic habitats and areas associated with state priority aquatic species; <br />d. Naturally occurring ponds under twenty (20) acres in size; and <br />e. Naturally occurring lakes over twenty (20) acres and other waters of the state, including <br />waters planted with game fish by a government or tribal entity.
