Section 4(f) Manual
January 2016

Section 4(f) of the United States Department of Transportation (USDOT) Act protects publicly owned parks, recreation areas, wildlife and waterfowl refuges, and public or privately owned historic sites from adverse impacts resulting from the construction of transportation facilities funded by the USDOT.

This manual has been developed by the Ohio Department of Transportation, Office of Environmental Services (OES) to serve as a guide for documenting and evaluating Section 4(f) resources affected by projects in ODOT’s transportation improvement program. It is meant to provide a basic understanding and overview of the 4(f) process; however, not every Section 4(f) circumstance will be specifically addressed. Therefore, it is important to consult with OES when a project involves a potential 4(f) property.

Training & Toolkit

An essential part of the Section 4(f)/6(f) process is training required by ODOT for vendors and staff who participate in ODOT projects. A toolkit accompanies the training and refers to the manual. Go to Section 4(f)/6(f) Training & Toolkit for more information about training.
