When the HESCO barrier was breached in Downtown Davenport this week, people had to move quickly. It was a matter of second before the flood levels got too high to navigate.

Since then, HESCO launched an investigation as to why exactly the barrier didn't work. According to WQAD, the findings so far indicate that it wasn't a matter of faulty structural integrity.

Per HESCO's statement in their report:

Following initial investigations we believe that either the flood conditions caused the road surface beneath the barrier to give way or the river crested over the height of the barrier. Our investigation so far indicates that there was no structural fault of the barrier.

With more rain on the way this week, things aren't exactly looking promising as far as the river crest goes.
