    Flood risk:LowNo BMA-documented flood-prone spot was found within 800 m of this location.Position is this project's approximate location (median of nearby listings), not this exact unit.Based only on proximity to points BMA itself has flagged as flood-prone or flood-watch — not a hydrological model, and not the 2011 flood extent. A location with nothing nearby is not proven flood-safe: BMA's list covers the spots it chose to document, not a wall-to-wall survey.
