This bill relates to the management of transportation projects in Minnesota. It mandates that before a transportation project or a group of projects (portfolio) can be included in the state or metropolitan transportation improvement programs, an impact assessment must be conducted. This assessment will check if the project complies with specific environmental goals, specifically the reduction of greenhouse gas emissions and vehicle miles traveled. If a project does not meet these targets, changes must be made to its scope or design, or it might even have to be removed from the portfolio. If these adjustments cannot assure compliance, the development of the project may be stopped, and it could be excluded from the transportation improvement program. This ensures transportation planning aligns with environmental and policy goals of reducing emissions and managing traffic volume.
