Huesca · Aragón · 81 km²
What rustic land in Aisa 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 2003. 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 Aisa. That is not proof there is no water: ask local drillers. 2 springs are recorded.
Ground: 72% practically impermeable; 9.5% karstic or fissured aquifer, high productivity; 8.4% porous aquifer, high productivity; 7.4% low permeability, local groundwater only.
Choosing where to drill takes a hydrogeologist.
