Description: This file is part of the Washington Department of Ecology Shorelines and Environmental Assistance Program identification of channel migration zones (CMZ) in selected streams of Mason County. The channel migration zone (CMZ) is the area along a river within which the channel(s) can be reasonably predicted to migrate over time as a result of natural and normally occurring hydrological and related processes when considered with the characteristics of the river and its surroundings [see WAC 173-26-020(6)]. The general channel migration zone includes the active channel corridor, the avulsion hazard areas, and the erosion hazard buffer. The active channel corridor generally corresponds to the meander belt of the active channel and has a width approximating the meander amplitude of the analysis reach. Avulsion hazard areas typically occur in side channels or low-lying portions of the floodplain that could be activated if accumulations of wood or sediment were to obstruct and deflect flows laterally, or if flooding were sufficiently intense The erosion hazard buffer was generally based on approximately 50% to 100% of the width of the active channel corridor and adjusted based on local conditions including geology, soils, geomorphology, and vegetation. The shapefile also includes polygons for the disconnected channel migration zone (DCMZ). This is the area located in the CMZ where publicly maintained man-made structures restrict channel migration [see WAC 173-26-221(3)(b)].
