Tribal governments select SHN for assistance on projects requiring environmental and biological planning, NEPA documentation, water and wastewater system designs, road designs, housing development planning, surveying, and special inspections during construction.  SHN’s locations in Northern California and Southern Oregon are geographically close to Tribal lands, allowing our staff to understand local planning and development issues that could affect tribal interests.

One example of how our local presence is a significant value to Tribes, is our work with the Wiyot Tribe, who asked us to assist in remediating environmental contamination related to an historical ship maintenance facility at the Indian Island Tuluwat Village site.  Recognizing the cultural sensitivity of the site, we worked with the Tribe to train archeologists so that they could recognize and preserve culturally significant features, while limiting their exposure to hazardous materials left from ship maintenance.  The site was remediated and returned to conditions reminiscent of the Wiyot Tribe’s past.  As a result, the Tribe was able to begin reusing their ancestral lands.


SHN has been an exceptional environmental service organization to work with…SHN gave a very competitive bid with the personal attention to detail making sure communication with the Tribe and Council was foremost. I would highly recommend SHN for environmental services based on their commitment to quality and effective relationship building coupled with their full complement of staffing needs relative to environmental issues.”
