ESA team members share a common goal of protecting, enhancing, and restoring the natural environment—from the headwaters to the coast—and creating resilient landscapes and recreational destinations that benefit our communities. Our experts pioneered some of the earliest wetland restoration planning efforts and published tidal wetland restoration design guidelines that are now widely used by restoration practitioners throughout the U.S.
Our interdisciplinary team of ecologists, hydrologists, biologists, geomorphologists, engineers, water quality specialists, and landscape architects work together to create practical, ecosystem-based designs. We blend rigorous scientific analysis with practical engineering solutions.
We offer a full range of restoration and conservation services to help clients solve mitigation challenges—from initial planning, feasibility studies, and conceptual design through permits, environmental compliance, and final design. We provide bid documents, construction phase services, and post-project monitoring to implement our designs, which allow natural habitats to reclaim their role in a healthy ecosystem.
Through stewardship of land and other natural resources, we preserve and conserve these assets while accommodating planned growth and development.
