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 12 wells and boreholes in Arroyo de San Serván. Half of the 12 with a depth found water at 4–15 m. One spring is recorded.
