(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.
