Environmental Review and Section 106

Environmental Review Record and Section 106 Historic Review Process

The National Environmental Policy Act of 1969 (NEPA) requires that environmental consequences are reviewed and alternatives considered for most federally assisted actions before decisions are made and before actions are taken. Therefore, an “Environmental Review Record” is required as part of the development due diligence process.

The National Historic Preservation Act of 1966 requires agencies to consider the impact of their federally funded developments on historic properties. This process is commonly known as “the Section 106 review”.

The ERR and the Section 106 processes are separate and distinct processes with different guiding regulations. IHCDA has combined the two processes into one process because both are federally required for the following IHCDA funding sources received from the Department of Housing and Urban Development: Community Development Block Grant (CDBG and CDBG Disaster), HOME Investment Partnerships Program (HOME), HOME Tenant Based Rental Assistance, National Housing Trust Fund, and Neighborhood Stabilization Program.

The Environmental Review Record (ERR) and Section 106 Historic Review User’s Guide and the ERR Workbook provides additional background information about the federally required processes including why the review is necessary, how to perform the review, and other resource information to help you complete the ERR Workbook. The ERR Workbook is the document where applicants will answer questions and submit supporting documentation regarding the project to satisfy the federal requirements for both the ERR and the Section 106 reviews. Applicants filling out the ERR Workbook will need to follow the User’s Guide and all appendices in order to fill out the ERR Workbook. Specifically, the User’s Guide and Appendix 3 Resources Document, will provide the information necessary to fill out the ERR Workbook.

The User’s Guide, all appendices, and fillable versions of the ERR Workbooks are available on this page and will also be available in the forthcoming updated CDBG and Home Program Manual.

Environmental Review Record and Section 106 Historic Review User’s Guide

The ERR and Section 106 User’s Guide was updated as of August 2018. Please use the new guide for all new submissions starting on August 16, 2018.


The updated ERR and Section 106 Historic Review User’s Guide and the Resource Document listed as Appendix 3 in the User’s Guide will be extremely helpful in answering questions related to the completion the ERR Workbook.
