enhancement, provided that federal and state resource agencies approve the mitigation plan and the plan achieves no net loss of wetland functions and values. (Ord. 2016-006, 2016) 17B.05.020J Aquatic habitat conservation areas – designation and mapping. 1. Designation and classification: Aquatic habitat conservation areas include: a. Those streams and lakes which meet the criteria for Type S, F, Np, and Ns waters, as defined in the water type classifications in the forest practices rules in WAC 222-16-030. Type S waters are synonymous with shorelines of the state. b. Areas with which federally and/or state-listed endangered, threatened, or sensitive aquatic species have a primary association; c. State priority aquatic habitats and areas associated with state priority aquatic species; d. Naturally occurring ponds under twenty (20) acres in size; and e. Naturally occurring lakes over twenty (20) acres and other waters of the state, including waters planted with game fish by a government or tribal entity. 2. Mapping: The approximate location and extent of aquatic habitat conservation areas are shown on the County’s critical area maps. These maps are to be used as a guide and do not provide definitive information about aquatic habitat conservation area size or presence. Other aquatic habitat conservation areas may exist that do not appear on the maps. The County shall update the maps as new aquatic habitat conservation areas are identified and as new information becomes available. (Ord. 2016-006, 2016) 17B.05.020K Aquatic habitat conservation areas – buffers. 1. Buffer widths: Buffers shall be established and maintained to protect regulated aquatic habitat conservation areas as shown in the Table at KCC 17B.05.020K-1 below. These stream buffers shall be measured in all directions from the OHWM as identified in the field. The buffer widths for Type S Waters are shown in the Table at KCC 17B.05.050-1. Shoreline buffers and vegetation conservation. Buffers shall not be altered except as authorized by this Program. These standard buffer widths are presumed to be adequate to protect aquatic habitat conservation area functions and values provided that the buffer contains relatively intact native vegetation at the time of the proposed use or development. Where the use is being intensified adjacent to a degraded buffer area that is not well vegetated, the Administrator may require the degraded area to be revegetated to maintain aquatic habitat conservation area functions and values. 17B.05.020K-1. Aquatic Habitat Conservation Area Buffers for Type F, Np, and Ns Waters Aquatic Habitat Conservation Area Standard Buffer Width Type F Waters 100 feet Type Np Waters 50 feet Type Ns Waters 30 feet
