Water Resources Engineering

ESA  Image

With more than four decades of on-the-ground experience solving complex water resource challenges, ESA specializes in the planning and design of multi-objective projects that integrate rigorous science with sound engineering fundamentals.

Our multidisciplinary team of engineers, ecologists, hydrologists, biologists, geomorphologists, and landscape architects collaborate to address a range of challenges affecting water infrastructure and the resiliency of aquatic ecosystems. Our strong understanding of natural systems—from creeks, rivers, and floodplains to wetlands, lagoons, and beaches—supports plans and designs that work with nature for enduring results. Whether it is bridge scour countermeasure design, culvert replacement, floodplain enhancement, or bank stabilization, we partner with clients to protect infrastructure, alleviate flooding, and enhance and restore habitat for native plants and animals. Using up-to-date climate change projections, we assess potential threats and opportunities unique to each site design, resulting in resilient projects.
