The Director mav require a habitat manaoement plan if - after considerinq the hvdroloqic. oeoloqic. and/or biolooical habitat connection potential and the extent and permanence of the buffer interruption - such a plan is deemed necessarv to confirm the lack of detrimental impact on the habitat area. 2 Multiple RMZs: ln the event that RMZs for any fish and wildlife habitat conservation area are contiquous or overlappinq. the most protective of the collective RMZs shall applv. 3 The Cascade and Columbia Plateau Ecoreqions are derived from the Water Resource lnventorv Areas (WRIA) 38. 39. and 40 ecoreqion boundaries. The Cascade Ecoreqion includes North Cascades. Cascades. and Eastern Cascade Slopes and Foothills ecoreqions. The Columbia Plateau Ecoreqion includes the shrub-steppe ecoreqion known as the Columbia Plateau. 5. lncreased RMZs. The Director shall increase the fish and wildlife habitat conservation area RMZ width where the standard RMZ is inadequate to prevent sionificant adverse environmental imoacts or to address hazards associated with the site or the proposed alteration or development. The Director may increase the buffer up to a maximum of two times the standard width. The Director shall consider increasino the RMZ when anv of the following conditions are present: a.The composition, quality and density of the buffer vegetation is insufficient to protect the habitat area: b.There is evidence of historical or current susceptibilitv to severe erosion. channel instabilitv. or aggradinq: c.There are multiple channels or islands present: or d.The land adiacent to the ordinarv hiqh water mark and extendinq throuqhout the standard habitat buffer is steeply sloped (qreater than forty percent (40%) slope) and there are no desionated landslide hazards such that an increased buffer mav be required to protect ecolooicalfunctions. 39
