Four Corner - Texas Water Development Board

C. Areas Potential Wetlands - A preliminary wetlands investigation consisted of a
review of all available published data for the study area including topographic maps, a
National Wetlands Inventory map (draft), aerial photographs, infrared aerial
photographs, and soil information published in the Soil Survey of Fort Bend County,
Texas.
Based on this preliminary investigation, numerous waters of the United States, including
wetlands, and areas potentially containing waters of the United States, were identified
within the boundaries of the study area. Following this resource review, ground truthing
field activities were initiated for the purpose of further identifying waters of the United
States, including wetlands, located within the study area.
The field investigation aspect of this project involved the systematic evaluation of all
readily accessible undeveloped parcels of property. Several inaccessible parcels of land
were however not physically visited during this investigation. Additionally, based on the
review of the published resources during the initial phase ofthis investigation, urban
areas (developed residential, commercial, or industrial properties) were not investigated
for potential wetlands. Also, several areas which could be inferred as upland areas based
on the resource review were not physically visited during this investigation. Though
numerous parcels of undeveloped land were physically evaluated during this study, each
parcel was not investigated as thoroughly as would be the practice during a more
extensive wetlands determination or delineation activity.
This preliminary wetlands investigation (both the resource rev1ew and the field
investigation) resulted in the creation of an exhibit which details the waters of the United
States, including wetlands, which were identified within the boundaries of the study
area. A cursory evaluation of the soils, hydrology, and vegetation in most of the areas
visited during the field investigation phase of this project was conducted based on field
conditions or reviewed resources. For the purposes of this preliminary wetlands
investigation, the undeveloped parcels of property evaluated during this study were
categorized as follows:
