What is an Environmental Review?

An environmental review assesses the potential environmental impacts of a project to determine whether it meets federal, state, and local environmental standards. Every HUD-assisted project must be examined to ensure that it does not negatively impact the surrounding environment and that the site itself will not have adverse effect on end users. The extent of the examination varies, but every project must be in compliance with the National Environmental Protection Act (NEPA) and other related Federal and state environmental laws.

The menu on the right of the page has links to several useful environmental resources. Please check this page regularly for updates. Extensive environmental review information is available on the HUD Exchange Environmental Review website.

If you have questions about environmental review, please contact the assigned Grants Management Specialist or Grants Evaluation Specialist for your Area Office.

HUD-wide Environmental Notice - HUD Balcony Policy under 24 CFR 51, Subpart B

January 6, 2017

CPD Notice 16-19 clarifies the Department’s approach to balconies within the Department’s regulatory constraints in 24 CFR Part 51 Subpart B, Noise Abatement and Control. The Notice changes HUD’s previous, informal policy of not allowing balconies off bedrooms and instead requires an Operations and Maintenance Plan with periodic inspections of seals and repair or replacement if necessary. The Notice reinforces that if the windows and doors serve as noise mitigation, a mechanical ventilation system must be installed. Questions about the Notice should be directed to Jim Potter at (202) 402-4610 or james.m.potter@hud.gov. Additional information about HUD’s noise regulation can be found on the HUD Exchange.
