Huesca · Aragón · 72 km²
What rustic land in Canfranc allows and holds, for the municipality as a whole. For a particular plot, open it in the map: the report answers for that exact point.
Can you build a house on rustic land?
Aragón requires at least 1 ha for a new house on rustic land.
DL 1/2014, art. 34.2. A town plan can be stricter.
Plan in force: Plan General (a full town plan), from 2002. The region's planning viewer ↗
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 Canfranc. That is not proof there is no water: ask local drillers. One spring is recorded.
Ground: 51% practically impermeable; 25% low permeability, local groundwater only; 13% porous aquifer, medium productivity; 5.2% karstic or fissured aquifer, medium productivity.
Choosing where to drill takes a hydrogeologist.
