Archaeology
ESA’s archaeologists provide critical thinking and measured analyses to guide project planning, permitting, and construction compliance. We bring experience and practical application to cultural resources evaluations to ensure technical excellence and regulatory compliance.
Our experts regularly conduct site investigations, assess the historic significance of resources, identify potential impacts, and plan effective mitigation strategies that emphasize avoidance, establishment of protective buffers, and documentation of lost or altered resources if necessary.
