Project Notifications

Public comment is encouraged throughout the planning and design of State Highway Administration projects. Certain regulations require the opportunity for additional review and comment specific to their jurisdiction. Please see the list below for current opportunities to provide input.


De Minimis Findings

Section 4(f) of the U.S. Department of Transportation (US DOT)Act provides protection to certain resources during the planning of transportation projects. Known as Section 4(f) resources, these include publicly owned public parks, recreation areas, and wildlife and waterfowl refuges, as well as significant historic and archaeological resources. When SHA and the responsible official(s) with jurisdiction over the resource agree the project will not adversely affect the resource, a de minimis (or minor) impact finding can be proposed. De minimis impacts are defined as those that do not "adversely affect the activities, features and attributes" of theSection 4(f) resource.

For parks, recreation areas, and wildlife and waterfowl refuges, public notice and an opportunity for public review and comment concerning the effects on the protected activities, features, or attributes of the property must be provided prior to seeking the Federal Highway Administration's approval on the de minimis finding.

PM2.5 Air Quality Findings

The results of air quality analyses for Fine Particulate Matter (PM2.5) hot-spot impacts associated with proposed State Highway Administration projects are outlined in Air Quality Technical Reports. The evaluation of PM2.5 is provided to meet the requirements of the Clean Air Act and the National Environmental Policy Act. For projects that do not result in a significant increase in the volume of diesel traffic, a notification, including the air quality technical report which contains this information, will be published on this website for a public comment period of 15 days.
