Colunga

Can you build a house on rustic land?

Asturias allows a new house on rustic land only where the town plan provides for it.

DL 1/2004, art. 124. A town plan can be stricter.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 1999. 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 7 wells and boreholes in Colunga. Half of the 6 with a depth found water at 11–50 m. 27 springs are recorded.

Ground: 48% practically impermeable; 23% low permeability, local groundwater only; 15% karstic or fissured aquifer, high productivity; 10% karstic or fissured aquifer, medium productivity.

Choosing where to drill takes a hydrogeologist.
