Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
322	The length of dike treated, or removed in miles. Report the full length of dike removed to match natural conditions. If the dike was breached report the cumulative length of openings created.; Estuarine: Habitat that is part of a semi-enclosed coastal body of water that is subject to the ebb and flow of tides, with one or more rivers or streams flowing into it, and with a free connection to the nearshore marine zone. This includes habitat impacted by the highest high and lowest low tides of a year. Estuaries are environments whose pH, salinity, and water levels are subject to the ebb and flow of tides, and the physical and chemical properties of the river that feeds the estuary and the ocean from which it derives its salinity. This habitat includes floodplain/riparian habitat subject to inundation from the tides.; Dike breaching: opens small sections or gaps in the dike to allow for hydrolic connectivity, but functionality may be impaired by the remaining large portions of the dike. ;	180

180. Enhance Floodplain/Remove, Modify, Breach Dike	Active	This work element is intended for the full or partial removal, breaching, lowering, and/or relocation/set-back of artificial levees or dikes adjacent to streams and estuaries for the purpose of floodplain, riparian habitat improvements. This WE may be the main emphasis of a stream habitat restoration project, or it may be a component of a broader set of techniques implemented in concert which collectively define a project. When this WE is used, the contract must also include 175. Produce Design . If the work includes improvement of fish passage into upstream reaches of the existing channel, then use 84. Remove/Install Diversion (Expired) , 85. Remove/Breach Fish Passage Barrier , or 184. Install Fish Passage Structure . If work is to create, restore, or enhance wetland function then use 181. Create, Restore, and/or Enhance Wetland .	2011		322	The length of dike treated, or removed in miles. Report the full length of dike removed to match natural conditions.
