We investigated this accident and determined that the trench was in a public right-of-way. It was not properly shored or protected in any way to prevent a collapse. No precautions were taken to keep pedestrians from entering the site – including children walking from neighboring residences to their local school. No alternate travel path was provided for pedestrians. Children were known to play in the construction zone. Cars and construction vehicles were allowed to travel adjacent to the trench in such a manner that they could precipitate a collapse. And the trench was not protected to prevent entry into it.
