Stuart Siegel and Wetlands and Water Resources, Inc. Join ESA


Environmental Science Associates (ESA), a leading West Coast-based environmental science and planning firm, announced that on April 1, 2014, Dr. Stuart Siegel and his firm Wetlands and Water Resources, Inc. (WWR), has joined with ESA. WWR is a San Rafael, California-based professional restoration design firm specializing in wetlands restoration and natural resource management, founded and led by Stuart Siegel PhD, PWS. The merger supports ESA’s strategy to further deepen our strategic and technical expertise in ecosystem restoration, regulatory compliance, environmental policy planning, climate change mitigation and adaptation, and applied science. This merger continues to build ESA’s growing restoration, water resources management, and coastal resiliency planning practice which includes the recent acquisitions of San Francisco-based Philip Williams and Associates and Portland-based Vigil-Agrimis.

“Dr. Stuart Siegel and his firm are well known for scientific-based environmental analysis, effective habitat restoration, and strategic policy-level planning and advising in the California Bay Delta. Our two firms share the essential core values of client service, technical excellence and credibility, and doing work that matters. This merger represents a significant step forward in implementing our strategy of investing in broader and deeper capabilities in restoration and natural resources management as we serve our clients in the California Bay Delta and elsewhere in the West and in the Gulf/Southeast region,” said Gary Oates, President of ESA.

Dr. Siegel notes that, “By joining ESA, we can provide our clients with the additional skills and deeper bench of expertise necessary to meet our society’s needs for large-scale ecosystem restoration, complex natural resource management, and climate change mitigation and adaptation. With the combined resources of ESA, we can now offer clients a more complete range of science, engineering, planning, and policy services necessary to meet these challenges.”

Stuart and his team of engineers, biologists and environmental scientists have been providing clients with premier environmental services for 18 years. They join ESA’s growing environmental hydrology practice team of more than 220 staff located in ESA’s Northern California offices. For more information about Stuart and WWR visit
