Description:
In October 2014, Seattle Public Utilities (SPU) completed construction of two large-scale floodplain reconnection projects in the Thornton Creek Watershed of northeast Seattle: Thornton Confluence and Kingfisher (Figure 1). These projects were designed to reconnect the stream laterally within its floodplain and also vertically with the hyporheic zone—the layer of saturated substrate beneath and adjacent to the active stream channel. Within this area of surface and subsurface/groundwater mixing, microbial and invertebrate assemblages carry out organic matter decomposition, nutrient cycling, and contaminant detoxification. With these projects, SPU seeks to: a) maximize onsite water, sediment, and wood storage with expanded floodplain and hyporheic capacity, b) slow erosive peak flows, c) modulate stream temperature, d) filter stormwater contaminants, e) increase in-stream hydraulic diversity, and ultimately f) improve the biological health of Thornton Creek.
