Why this page matters

Section 106 consultation depends on knowing the federal nexus (is there a federal agency that must consult?), tribal nexus (do sovereign tribes need to be consulted under NAGPRA or NHPA §106?), and environmental nexus (does FEMA flood designation trigger additional review?). A typical scoping memo takes 30–60 minutes of cross-referencing FOIA'd shapefiles today; here it's one click.
