The SIU does not map land classes here: the town plan is the source.
Only the town hall can confirm it, in writing: ask for a certificado urbanístico.
Is there water?
No well or borehole is recorded in Calañas. That is not proof there is no water: ask local drillers.
Ground: 64% practically impermeable; 36% low permeability, local groundwater only.
Choosing where to drill takes a hydrogeologist.
