ERG's engineers have permitted pipeline stream crossings, designed and installed “hard” and “soft” erosion-control structures, and designed a stream by-pass channel.

ERG secured permits for installation of drainage culverts between Highway 93 and Montana Rail Link tracks.

ERG surveyed, designed, and acquired permits for Mission Creek restoration following damages from a landslide.

ERG obtained necessary environmental and construction permits, maintained contact with agencies, and assisted in site assessment.

Environmental Engineering

Environmental engineering is a relatively new branch of engineering that combines civil, sanitary, chemical, geotechnical, mining, and other traditional engineering disciplines.  It has evolved into a much broader field with several practical applications including:

• Stream and groundwater restoration design
• Stormwater system design
• Permitting
• NEPA compliance
