Environmental Science & Assessment (ES&A) provides natural resources management services and environmental documentation for public infrastructure projects, public and private facility expansions and private development.

Wetlands
ES&A’s project work includes wetland reconnaissance, delineation, mitigation planning and bioengineering design. Our expertise in botany, soils and surface water hydrology assists us in evaluating a range of sites from pristine wetlands and streams to those subject to severe historical disturbances.

Wildlife
We conduct wildlife studies that include amphibians, reptiles, birds (including shorebird census for North American flyway) and mammals. Our experience includes evaluating sites for presence, signs of presence (i.e., tracks, scat, etc.) and habitat types.

Endangered Species Act
ES&A conducts sensitive species impact evaluations and prepares documents for compliance with the Endangered Species Act, including Biological Assessments and Habitat Conservation Plans. We perform surveys for a variety of sensitive, threatened and endangered species including steelhead, chinook and coho salmon, coastal cutthroat trout, Oregon chub, Nelson’s checker-mallow, Bradshaw’s lomatium, bald eagle, marbled murrelet, snowy plover, western painted turtle and northern red-legged frogs.

Environmental Permitting
We prepare state and federal and state environmental permits (Corps Section 404/DSL Removal-Fill), permits for local jurisdictions (building and land use) and for infrastructure (Union Pacific Railroad, Oregon Department of Transportation, Oregon Department of Environmental Quality). Our expert knowledge of environmental regulations and strong working relationships with local, state and federal agencies ensures that our clients receive required approvals at reasonable cost and with minimal delay.

NEPA/SEPA
We prepare NEPA Environmental Assessments (EA’s) for a wide range of infrastructure projects including pipelines, roads and bridges. We also prepare SEPA checklists and EA’s for jurisdictions in Washington State.
