City planners were inspired by urban concepts used in the design of Washington, D.C. (1791) and Paris (1850). These were characterized by very wide streets and bold outlines, with diagonal streets converging at important points.

Key elements of its design include a perpendicular grid of streets cut by diagonal avenues, blocks of regular dimensions and a promenade around its perimeter. The municipality is located north of Rio Grande do Sul, in the Upper Uruguay, on the ridge of the Serra Geral. The origin of the name of Erechim refers to the ancient indigenous inhabitants of the region, and comes from "Caingangue, which means "small field"; it probably was given this name as the city was surrounded by forests at the time.
