Company Vision and Purpose

Soil contamination is a significant environmental concern that poses long-term risks to both ecosystems and human health. When pollutants and toxins infiltrate soil, sediment, groundwater, or surface water, they can cause serious harm to living organisms and disrupt ecological systems. Soil remediation involves various processes aimed at decontaminating soil by removing or converting pollutants into less harmful substances.

Projects

Corporate Building

SB 131’s “near-miss” rule allows for streamlined review of a residential project that meets all but one condition for a CEQA exemption and does not violate select criteria.

Esthetic Building

The current Nationwide Permits will expire in March 2026. The following distillation from our permitting experts shares some of the proposed changes from the U.S. Army Corps of Engineers.

Cultural Building

Riparian ecosystems play a critical role in the landscape by supporting key ecological processes and functions that sustain both aquatic and terrestrial habitats. These transitional zones, typically located along rivers, streams, and other flowing waterways, connect land and water systems; they regulate stream temperature, filter runoff, stabilize banks, and contribute organic material that supports biodiversity.

Services We Offer

Air Quality

Our air quality team serves a wide range of clients and supports the development of environmental reviews, air permitting, compliance, health risk assessments, due diligence studies, and expert witness support. Our employee-owners have the expertise and experience to approach complex projects with an eye toward providing technically sound results and actionable insights.

Climate Change & Resilience

We have been working with communities to plan for and directly address climate change impacts to protect people and resources in the face of rising sea levels, flooding hazards, increased heat and drought, wildfire hazards, coastal erosion, and more.

Environmental Permitting & Compliance

Securing all necessary environmental permits and approvals for projects and documenting compliance has become increasingly challenging in today’s regulatory environment.

Biological Resources

The sustainable conservation and responsible stewardship of our biological communities is central to many planning efforts in a rapidly changing global environment.

Cultural & Historic Resources

We only get one chance to preserve irreplaceable historic artifacts, remains, and resources. ESA’s cultural and historic resources team gives voice to those whose voices have been lost to time. We study who and what came before so that we can share our rich and diverse history, insights, and lessons to inform the future.

Environmental Review & Documentation

When the National Environmental Policy Act (NEPA) into law on January 1, 1970, by then-President Nixon, it was the first national law that encouraged balance and harmony between man and the environment.
