As part of the Environmental Assessment effort for the Reconstruction of Runway 8-26 at Rafael Hernandez Airport, MARLIN performed wetland delineation work which included measuring current wetland status over the proposed area to be impacted by the reconstruction. Evaluation criteria used were those required for an official jurisdictional wetland determination regulated by the US Army Corp of Engineers (USACE).
The methodology employed for this study consisted of an overall assessment of existing literature and geographic maps to determine potential presence of jurisdictional wetlands within the project area regulated by Section 404 of the Clean Water Act, under USACE’s jurisdiction.
A detailed screening analysis was performed using Geographic Information System (GIS) tools, aerial photographs, and a field evaluation by wetland specialists. The evaluation was focused on identifying attributes that are required criteria for wetland areas, such as: (1) hydrophytic vegetation; (2) hydric soils; and (3) hydrological conditions (inundated or saturated).
MARLIN personnel performed field work consisting of surveying the entire project area, mostly focusing on stormwater infrastructure and sinkhole areas particular to this project. During the field evaluation, it was confirmed that the project site has been modified for airport activities, and that the unpaved areas were altered to convey stormwater coming from runway and taxiway areas.
