HVJ Associates, Inc. completed a geologic fault assessment of a large tract slated for development as part of the Ellington Field Spaceport at Ellington Airport in Houston, Texas. The acreage is currently partially developed with runway facilities and several roads.
At HVJ Associates, Inc., our task was to provide complex geologic faulting delineation services at Ellington Field for the EFD Spaceport project. We reviewed published and unpublished literature on faulting in the areas, site reconnaissance, the installation of a series of deep boreholes, geophysical logging of these boreholes and surface profile surveying to determine scarp locations.
The data for this study showed that a fault appeared to be present beneath the proposed spaceport. The fault extended to the ground surface, which supported our recommendation of a fault hazard band along a portion of the proposed Spaceport area.
HVJ Associates geologic and engineering personnel interpreted gamma-ray logs, elevation profiles, and other data. We concluded the potential for active surface faulting to the proposed project area was high due to the geologic faults transecting the EFD Spaceport area.
