A Hybrid Engineering and Contracting Firm

Arroyo Geoscience is a engineering contracting company based out of Los Angeles.  We specialize in bridging the gap between geotechnical and environmental engineering, and environmental contracting, remediation, and installation of environmental mitigation systems.

Our team brings together specialists in several different interdisciplinary professions, including civil and geotechnical engineers, engineering and environmental geologists, environmental engineers, expert technical drafting team, and septic system engineers and consultants.

While many other firms specialize in one or the other but rarely both. We at Arroyo Geoscience realize that many projects require the professional expertise of geotechnical as well as geological and environmental experts, as well as engineering contractor expertise.

What is an Arroyo?

Those of us who were not raised in the southwest may not be familiar with the term Arroyo.

Arroyo is a Spanish term for a stream, but in the Southwest, the term is commonly applied to stream beds that are dry most of the time.  The southern California area is famous for its many arroyos, including the Arroyo Seco and the Los Angeles River. 

We chose Arroyo for our company name because of its intimate connection with the southwest United States, and also because arroyos are environmentally sensitive areas.
