About Our Services

We are a highly specialized environmental consulting firm committed to restoring the natural functioning aspects within the watershed. This is accomplished through the practice of soil bioengineering as an integrated technology that uses sound engineering practices in conjunction with ecological principles to assess, design, construct and maintain living vegetative systems to repair damage caused by erosion and failures in the land and to protect and enhance healthy functioning systems. We offer both consulting design and design build services.
