Metric Guidance

Metric Guidance ID	Description	Used on Work Elements
330	Identify the total acres of wetland habitat created in the estuary habitat zone. To calculate acres, use a GIS program or approximate the value by multiplying the total length of the protected habitat zone times the average width of the protected habitat zone in feet / divided by 43,560 sq. ft./acre. -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. -Creation: The manipulation of the physical, chemical, or biological characteristics present to develop a wetland on an upland or deepwater site, where a wetland did not previously exist. Establishment (creation) results in a gain in wetland acres.	181

181. Create, Restore, and/or Enhance Wetland	Active	This work element is intended for the creation, restoration, or enhancement of wetland hydrologic, water quality, or habitat functions. Actions include installation of a water control structure, re-contouring, or floodplain reconnection . Wetland creation (establishment) is the manipulation of physical, chemical, and biological characteristics to develop a wetland on a site where one did not previously exist. Creation results in a gain in wetland acres. Wetland restoration (re-establishment) is the manipulation of the physical, chemical, and/or biological characteristics of a site with the goal of returning natural/historic functions to former wetlands that may have been filled, subsided, or impacted by hydrologic alterations. Restoration reestablishes a former wetland and results in a gain in wetland acres. Wetland enhancement is the manipulation of the physical, chemical, or biological characteristics of a site with the goal of repairing degraded wetland functions. Wetland enhancement typically involves the manipulation of site characteristics to improve hydrologic, water quality, or habitat functions but does not result in a gain in wetland acreage. This WE may be the main emphasis of a stream/wetland 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 additional actions or techniques are implemented, make sure you properly document associated work elements, e.g., 180. Enhance Floodplain/Remove, Modify, Breach Dike , 184. Install Fish Passage Structure , or 29. Increase Aquatic and/or Floodplain Complexity , 30. Realign, Connect, and/or Create Channel , or 35. Develop Pond .	2011		330	Identify the total acres of wetland habitat created in the estuary habitat zone.
