Idaho State Statutes - Idaho Attorney Directory

(1) Precinct boundaries shall
follow visible, easily recognizable physical features on the ground including,
but not limited to, streets, railroad tracks, roads, streams and lakes. The
exception shall be when a precinct boundary coincides with a city, county,
Indian reservation or school district boundary which does not follow a visible
feature.
(2) In order to achieve compliance with the requirements of this section,
and simultaneously maintain legislative district boundaries which may not
follow visible features, a county may designate subprecincts within precincts,
the internal boundaries of which do not follow visible features.
