Wetlands Delineation and Location Surveys belong in a category all on their own; they are performed when construction work that is being planned on or near a site containing defined wetlands. Local, state, or federal regulations vary, but wetlands are usually classified as areas that are completely inundated with water more than two weeks during the growing season. Boundaries of wetlands are determined by observing the soil colors, vegetation, erosion patterns or scour marks, hydrology, and morphology of the land in question. Data is then collected on the locations of the placed flags and a plan is drawn to reference the boundary of the wetlands and compare it to the proposed boundaries of the surrounding plots or parcels of land and the construction work proposed within.
