Valle de Ollo / Ollaran

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: Plan General (a full town plan), from 2000. 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?

IGME records 16 wells and boreholes in Valle de Ollo / Ollaran. Half of the 16 with a depth found water at 178–250 m. One spring is recorded.

Ground: 44% karstic or fissured aquifer, high productivity; 33% practically impermeable; 14% low permeability, local groundwater only; 6.2% porous aquifer, medium productivity.

Choosing where to drill takes a hydrogeologist.
