Lost Decade Culvert, Part 1

I was in Japan in the early part of its now-famous "lost decade" when the government was funding unnecessary public works projects to stimulate employment. My neighborhood project (about two blocks from my apartment) was turning a natural creek into a concrete culvert. I described it from Alex's point of view in American Fuji (p.277): "The chain-link fence on either side of the culvert was coated in toothpaste-blue plastic. Natural mud banks covered with grasses and hydrangeas stopped abruptly at new concrete walls flanking the stony stream." This photo almost shows the mud banks. I'm facing the ocean, looking downstream.
