Collapse risk and debris at the intersection of Verseny Street and Jobbágy Street

There is a small park at the intersection of Verseny Street and Jobbágy Street, next to which there was quite a serious fall of plaster from the house, and in particular whole bricks fell. This happened about a week and a half or two ago. The pile of shit has been there on the street ever since, it was just swept next to the wall, but no decontamination was done, no signs were posted to prevent anyone from walking there. This really bothers me, because although I avoid it, my 3 children and many other passersby may not do so. I would like the facade of the affected house to be decontaminated and the shit to be removed from the street so that it is safe to walk there.
