Cultural Resources

Paleontological Resources

LSA can help you navigate the full spectrum of federal, State, and local environmental review requirements governing the management and preservation of cultural resources. We back up our knowledge of the regulatory framework with region-specific expertise, professional certifications, and fully appointed laboratory facilities. Our specialists address regulatory requirements pertaining to archaeology, architectural history, local and regional history, cultural landscapes, Native American consultation, and traditional cultural properties. We identify issues early in the planning and design process when the most cost-effective solutions are possible.
