My home is located 100 cm above the sea level (the entrance only, I live at the first floor!). When the tide rises it happens it going to get flooded, and we must wear plastic boots to walk.
in this panorama i drew 3 levels the water can reach, there are critical for me and for the citizens of Venice. From the darkest to pale blue-green:
30 cm above the seal level - the tide when I got the snapshot
110 cm above the sea level - the level of the flooring facing the canal. During early 2000s the City of Venice did huge works to rise, when possible, the flooring to this level http://smu.insula.it/index.php@lang=en.html
140 cm above the sea level - when the MOsE barriers are being activated https://www.mosevenezia.eu/?lang=en
187 cm above the sea level - the level the tide reached on 12th November 2019, the second-highest tide ever (Acqua Granda). the MOsE was not working that horrible night.
The audio file is the alarm you can hear when an exceptional high tide is coming https://www.comune.venezia.it/it/content/sirene-allertamento-acqua-alta
