Four Corner - Texas Water Development Board

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.
2.2.3 FIELD INVESTIGATION
In order to determine the potential presence and extent of jurisdictional waters of
the United States, including wetlands, located within the study area, a preliminary
wetlands determination was conducted. The wetlands field investigation of the
study area was conducted over the course of four days; field investigation dates
included October 15, November 9, November 10, and November 19, 1998.
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 of this 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.
2.2.4 WETLANDS INVESTIGATION FINDINGS
This preliminary wetlands investigation (both the resource review 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
Four Comers Area Water and Wastewater Facilities Planning Study
