Rustic land in Spain, municipality by municipality › Navarra
Eratsun
Navarra · Navarre · 26 km²
What rustic land in Eratsun 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?
Navarre allows a new house on rustic land only where the town plan provides for it, on at least 1 ha.
DFL 1/2017, art. 115. A town plan can be stricter.
Plan in force: Delimitación de Suelo Urbano (only marks the town's edge), from 1976. 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 Eratsun. That is not proof there is no water: ask local drillers.
Ground: 65% practically impermeable; 14% low permeability, local groundwater only; 7.9% karstic or fissured aquifer, high productivity; 7.3% karstic or fissured aquifer, medium productivity; 6.1% porous aquifer, high productivity.
Choosing where to drill takes a hydrogeologist.
