    Flood risk:HighNearest: ถนนพระรามที่ 3 ซอย 16 (documented flood trouble spot) · ~168 mThis location is right next to a spot BMA has documented as flood-prone or flood-watch.1 documented spot within 300 m3 documented spots within 800 mPosition 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.
