GSG’s team of natural resource scientists strive to completely and accurately document all environmental resources that may have an effect on project planning and development, including wetlands, waterways, endangered species, and historic properties. Our goal is to work with project planners and designers to minimize impacts to these features to expedite project approval, save project costs, and preserve the natural environment.  We incorporate sustainability and avoidance/minimization practices in all aspects of project planning and construction.  Our scientists are experts in the fields of biology, botany, soil science, hydrology, and erosion control. Our staff has more than 40 years of experience performing wetland delineations, tree surveys, endangered species surveys, sediment and erosion control projects, as well as wetland and waterway restoration projects.  Our scientists are constantly searching for ways to apply emerging technologies to create innovations that aim to protect, maintain, and preserve natural resources.
