This story illustrates perfectly why there's no such thing as a simple solution. This city has spent $50,000 over at least five years to resolve this one issue. Feel free to groan along in empathy, as I did when I heard it at the International Erosion Control Association's annual conference.rnSometime in the 1980s, an open channel is dug behind a subdivision. Homeowners agree to maintain it, but the developer neglected to install gates in the fence that separates their backyards from the channel. But that's just as well, because the city approved a 10-foot channel-bottom design with 3:1 slopes: too steep for safe mowing.
