Title 23 › CHAPTER 1 — FEDERAL-AID HIGHWAYS › § 169
Allows a State or metropolitan planning organization to create one or more programmatic mitigation plans as part of transportation planning. Plans can cover a region, ecosystem, watershed, or a whole state. They can include many resource types or just one (for example, aquatic areas, parks, or wildlife habitat). Plans can address all projects in the area or only certain project types. The planning group must decide the plan’s scope in consultation with the agencies that manage the affected resources. Plans can assess resource conditions and threats, spot opportunities to improve resources, set standard mitigation actions, set rules for how much mitigation is needed (for example, ratios or site criteria), include monitoring and ways to adjust actions over time, and note any legal requirements. Before adopting a plan, the planner must consult resource agencies, publish a draft for agencies and the public, consider comments, and address them in the final plan. Federal agencies must give substantial weight to the plan’s recommendations when doing reviews under the National Environmental Policy Act of 1969 or other federal environmental laws. This does not limit using other programmatic approaches for NEPA reviews.
