Environmental Assessment


Responsible entities, recipients, applicants, and partners are required to conduct an environmental review before beginning a HUD-funded project. The environmental assessment is one of the five levels of environmental reviews listed in 24 CFR Part 58 and 24 CFR Part 50; this level of review, prepared under the National Environmental Policy Act, is typically required when a proposed project has activities such as new construction or a change in land use. Environmental assessments are essential in determining how a project may affect the environment and how the environment may affect the project.

Environmental Assessment Factors and Categories eGuide

When an environmental assessment is required under 24 CFR 58.36 or 24 CFR Part 50 Subpart E, responsible entities, recipients, applicants, and partners must thoroughly investigate the impacts of the project on the surrounding environment, community, and population and the impacts of the surrounding conditions on the project. This Environmental Assessment eGuide will help environmental review preparers review all aspects of their project.

The National Environmental Policy Act (NEPA), 42 U.S.C. § 4321, requires each federal agency to determine the environmental impacts of its actions. Agencies assess impacts according to regulations published by the Council on Environmental Quality at 40 CFR 1500. NEPA’s environmental assessment process forms the policy basis for each of the following environmental factors.

The Environmental Assessment eGuide is fully searchable and updated with the latest requirements, resources, and best practices for conducting an environmental assessment. To navigate this eGuide, click through each of the factors and their categories to find relevant guidance and information.
