(Ed.note: This was a comment under the pictures sent by Mark. I have posted the comment for better visibility.)
"One interesting point in these pictures from Mark's vantage point is the water over the berm from the Westfield Meadows green space.
"It looked as if the WM pond held hardly any water Tuesday morning, that there was more than the greenspace could clear to the outfalls for the ditch and that the Westfield Meadows water had overwhelmed the berm and was adding to the backup in the Abey system.
Add to that the fact that the wierplate in the box culvert on Porter had failed along the eastern edge and was bypassing far more water than planned to the Westfield Meadows system. It was clear from Saturday's rain that the plate needed to be calibrated to slow the rate of discharge. that would have been fairly simple.
Some time between 6 and 7 AM Tuesday the plate failed and needs to be put back in place or replaced with a higher notch to haold water in the pond longer.
The pictures here and the ones I took from my house show clearly that, contrary to assurances, Westfield Meadows has not taken care of their additional runoff and that, even though the Abey system is working well right now, it is not working alone and cannot handle the overflow from Westfield Meadows and the overflow from the R&K pond at Vision and 6th.
The Weather Service is calling for 3 more inches of rain tonight. I'm not confident in the capacity of the system right now.

There seems to be a lack of consistency between the text of the post and the Observer's headline. We do not know if the engineering failed, in this sense: We do not know if the the overall design of the system failed. The execution of one mechanical component within the system failed, and that might have caused the entire system to fail. Fix that one mechanical component so it functions realibly as it was designed to function, and the whole system might work. Let's not jump to conclusions not supported by the facts available to us.
