There are different types of flooding the main ones being what occurred in the 1800’s, 1974 and more recently in 2011 & 2013. But most are unaware of local flooding that occurs much more often and possibly a number of times in a year. These photos are of the latter category as indicated by debris and water line on the steel columns. This property is in a low lying north east suburb. Possible causes may be the nearby creek or inadequate street drainage (or blocking). Doesn’t matter too much what the cases may be, the main concern is that it happens way too often and when least expected.
