Dike setbacks and other projects that increase connectivity between the channel and its floodplain or between the channel and existing off-channel habitat.  Does not include digging artificial channels. The Union Gap reach of the Yakima River between Naches River and Wapato Dam is considered to have very high restoration potential. It is one of the only mainstem reaches that is not currently limited by severely altered flow and temperature regimes. YRBWEP has purchased large areas of floodplain habitat to the east of the river. The majority of this area is currently isolated by levees and passage barriers. Yakima County Flood Control Zone District is proposing to set back the levees in this reach to significantly increase the size of the active floodplain, including on the YRBWEP properties. WSDOT has constructed a new bridge at SR 24 which is much longer than the old bridge to allow the levee setback to proceed. Floodplain restoration work is being coordinated with Central Pre-mix's gravel mining operation.
