I saw a road in my neighborhood go from trenches along the road to full storm drains and sidewalks, for seemingly zero reason but to let the existing owners appraise their homes for $10k more. The trenches were fine in practice and never spilled over even in the worst storms. This suburb of 15 thousand people is currently millions of dollars in the hole doling out shortsighted handouts like this, and there are thousands of suburbs just like this one.
