Based on 6 leveling sections across the tidal zone of Tianjin Binhai New Area, the height and slop of tidal zone were measured and calculated. The elevation of the interface between anthropogenic coastline (seawall, coastal road and so on) and the natural tidal zone is from +0.22 m～+0.73 m (1956Huanghai Elevation System). This paper presents that the coastal embankment has really become the only barrier protecting the urban safety, so further heightening, strengthening coastal defense facility, upgrading prevention level is necessary.
