Huge thank you to 1400+ contributors. We appreciate your feedback.
The Planner's Guide Equity in Public Engagement guidebook is the result of a large-scale collaborative process that involved a forum with an expert panel and peer-to-peer dialog with participants, an interactive webinar with the Federal Interagency Working Group on Environmental Justice (EJ IWG) and an industry-wide conference on Virtual Public Involvement. Many thanks to these agencies and firms for contributing to this guidebook.
