Condado de Treviño

Can you build a house on rustic land?

Castilla y León allows a new house on rustic land only when a farm needs it. Otherwise it has to go in a village, or restore a building.

Ley 5/1999, art. 23.1.e. A town plan can be stricter.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 2022. The region's planning viewer ↗

The national urban information system (SIU) maps the land class for 100% of the municipality.

Only the town hall can confirm it, in writing: ask for a certificado urbanístico.

Is there water?

IGME records 10 wells and boreholes in Condado de Treviño. Half of the 10 with a depth found water at 206–3,134 m. 7 springs are recorded.

Ground: 45% practically impermeable; 26% low permeability, local groundwater only; 13% porous aquifer, medium productivity; 7.1% karstic or fissured aquifer, high productivity; 7.1% porous aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
