What is wetland delineation? Wetland identification and delineation establishes the existence (location) and physical limits (size) of a wetland for purposes of complying with the Clean Water Act and other federal, state, and local regulations.
What is Wetland Delineation? Wetland delineation is the fieldwork that determines the boundary between uplands and wetlands on a property. This on-site work follows guidelines established by the United States Army Corps of Engineers (USACE) and is required for permitting purposes.
Wetland delineation is the process of identifying, characterizing, and mapping wetlands on a property. This process involves a combination of fieldwork, data analysis, and consultation with regulatory agencies.
The 1987 Corps of Engineers Wetlands Delineation Manual and Regional Supplements organizes characteristics of a potential wetland into three categories: soils, vegetation and hydrology. The manual and supplements contain criteria for each category.
A wetland delineation is a process of identifying the boundaries and characteristics of a wetland area in accordance with the standards set by the U.S. Army Corps of Engineers (USACE) and the Environmental Protection Agency (EPA).
What is wetland delineation? Wetland delineation establishes the existence (location) and physical limits (size) of a wetland for purposes of federal, state, and local regulations. Wetland delineation is also an element of a jurisdictional determination.
Delineation is the process by which boundaries of existing wetlands are defined and area is measured – a critical component of the mitigation banking system of credit offsets. Since 1991, Minnesota has regulated a “no net loss” of wetland area within the state.
Determination of the boundary between wetlands and adjacent uplands is termed wetland delineation. Specific methods, identified by federal or state agencies or municipalities, are employed to determine wetland boundaries within landscapes.
A wetland delineation establishes the location, size, and boundaries of a wetland for federal, state, and local regulation purposes. It also helps landowners identify jurisdictional determination, which is a process used to define waters of the United States.
Before any of these activities can commence, wetlands need to be defined in such a way that they can be mapped through remote sensing techniques and by ground surveys. This contribution provides an introduction to wetland delineation with a focus on US practices.
