amanzanar

A narrow urban-planning term meaning to lay out land into manzanas (city blocks) — used specifically in descriptions of town planning and land subdivision, not in general conversation.

• El nuevo barrio fue amanzanado siguiendo una cuadrícula regular. — The new neighborhood was laid out into blocks following a regular grid.
• Los urbanistas amanzanaron el terreno antes de venderlo por lotes. — The urban planners divided the land into blocks before selling it off in lots.
• La ciudad colonial se amanzanó siguiendo el modelo español clásico. — The colonial city was laid out in blocks following the classic Spanish model.

Expecting amanzanar to mean any kind of city planning — it's specifically about dividing land into rectangular blocks (manzanas), not planning streets, zoning, or infrastructure generally.
