You did not answer my question. You negotiated a gravel removal plan. I have no problem with that. But I do have a problem with the way in which it was done.
As a precaution, the department was responsible for ensuring that there would be enough water flowing through. That was not done. I do not know why, because you have not answered my question.
Why did the department not install culverts that were big enough to ensure that the flow would not be affected? It's simple. I am sorry, but it isn't rocket science to ensure that you have big enough culverts to allow an acceptable flowthrough. Basically, what you are saying is that you used big rocks then realized that the water was not getting through.
Can you believe it? Come on!
It is all well and good to have a gravel removal plan, but there is a limit to how much you can disregard. Just install culverts that are the right size, and that will take care of it. Nothing could be simpler. It is not rocket science!
