In my last column, I provided some information that was inaccurate. Unfortunately, the real information is worse. I had said that the proposed South Boulder Creek dam along U.S. 36 and Table Mesa Drive would “protect” around 600 structures for a cost of around $90 million.  The 1/25/24 council memo states that 600 structures are in that floodplain and that the South Boulder Creek Flood Mitigation Project will protect only 260 of them from a 100-year flood. If 260 structures are “protected,” then that leaves 340 “unprotected.” Redoing the math, the $90,000,000 estimated cost figure I used divided by 260 structures is almost $350,000 per structure, over a third of a million dollars! I immediately communicated this much larger number to the City Council, figuring that the shock might stir some serious rethinking. I did not receive a single reply. I also made a request under the Colorado Open Records Act (CORA) for “the most recent detailed updated cost estimate for the project” (along...

I just read an excellent paper called  “The Questionable Economics of the 15-Minute City”  by Rachel Meltzer, a professor of planning and urban economics at Harvard. To quote her, “The economics of the 15-minute city don’t really work.” Her analysis points out that any kind of establishment, whether it is a supermarket or an urgent care clinic, has fixed costs. So, the “catchment area” needs to be big enough to have enough customers to cover those costs. Also, many stores have become bigger and contain a wider variety of goods than 20 or 50 years ago. Thus, any given area is now served by fewer stores with more goods per store. Looking at Boulder, we see these economics at work. For example, we have about 10 grocery stores, and over the last years, we’ve had two supermarkets close and a couple of new ones open, that I can think of. And they are mostly distributed geographically. So, even with all the planned growth in East Bo...
