Maybe they walked up and down the creek to see how many other spots are getting blocked like your area. Get it all at once, whenever they decide to get around to it. As I recall, the whole creek is jungly and there’s probably a lot of tree trash along its course.
Jungly is a perfect definition. LOL! And I hope that is what they were doing. And they could have checked the weather reports and decided to wait til the rain stops and see where the trash being washed downstream has stopped. I’m looking forward to checking out there tomorrow.
This section of the creek goes straight to the corner of the school yard and makes a 90 degree turn to follow another side of the school. The water comes out of a culvert, but from where, I don’t know.
