About Our Assessment Services

Our assessments provide the basis for making informed decisions. Our diverse evaluations include biological resource assessments to document conditions, identify constraints, evaluate impacts, explore alternatives, and propose mitigation measures. These evaluations often align with regulatory frameworks like the California Environmental Quality Act (CEQA) or the National Environmental Policy Act (NEPA). Our expertise covers a wide variety of assessments for all types of terrain, allowing us to provide vital knowledge for our clients.

Types of Assessing

Biological Resource Evaluations

Reconnaissance-level assessments used to document baseline biological conditions, identify biological constraints, evaluate project impacts, assess project alternatives, and identify avoidance, minimization, and mitigation measures. Often performed in compliance with the California Environmental Quality Act (CEQA) or the National Environmental Policy Act (NEPA)

Biological Assessments

Assessments conducted on behalf of a federal agency to document the effects of a proposed action on species listed under the federal Endangered Species Act

Wetland Determinations & Delineations

Site assessments using the U.S. Army Corps of Engineers 3-parameter approach to determine if wetlands are present and, if present, delineate their boundaries relative to non-wetlands, property boundaries, and project footprints

Conservation Value Assessments

Assessments of a property’s special-status biological resources and potential to provide mitigation or compensation for offsite impacts under a conservation easement

Ecological Risk Assessments

Assessments that evaluate the likelihood that alternative actions may have adverse ecological effects, estimate the type and severity of those effects, and ultimately provide a systematic approach to aid those who must make decisions in the face of uncertainty

Peer Review

Critical assessments of biological resource sections of environmental compliance documents, natural resource management plans, habitat conservation plans, and other documents and reports to evaluate validity of information and analysis


Through our work, we support our clients on projects that require knowledge about pertinent state and federal laws, as well as the flora and fauna of the region. Learn more about the species we often see and the regulations that often affect our clients by exploring our resources.
