Lerma

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 1996. The region's planning viewer ↗

The national urban information system (SIU) maps the land class for 99% of the municipality.

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

Is there water?

IGME records 6 wells and boreholes in Lerma. Half of the 6 with a depth found water at 140–180 m.

Ground: 55% low permeability, local groundwater only; 25% karstic or fissured aquifer, medium productivity; 13% porous aquifer, high productivity; 6.8% karstic or fissured aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
