In the city, an alarm was organized for the time of the opening and freezing of the Neva, as well as for the beginning of the flooding. The article analyses the decrees of Peter I and the orders of the local administration, which were designed to minimize the damage, and established standards for the construction of new buildings and piers. The article is accompanied by a letter of the Kotlin commander Vasily Poroshin on the consequences of the flood of 5 November 1721.
