The implicit theory of growth behind Boulder’s current expansion is that it can become a fast-growing commercial center and retain its residential quality of life at the same time. That idea is proving to be a fantasy, along with many of the other visionary positions of our local government.Now the City Council has voted overwhelmingly to insert co-op housing in virtually any zoning district in the city and is pushing density through such bizarre ideas as “density transfer.” The inadvisability and destructive quality of this pro-density and anti-neighborhood position has been ably described in dozens of letters to the Daily Camera, as well as in editorials by Leonard May, Steve Pomerance, Spense Havlick and others.The indisputable fact is that the unaffordable housing problem is being driven by the push for commercial expansion. As one letter write wrote prior to the 2015 election, “You can’t build your way to affordable housing” — as has been demonstrated in San Francisco and Aspen. Boulder has fallen behind the wisdom of Palo Alto and other cities, which now understands this fallacy well. “Affordable” housing is really only more building, and not affordable at all. Indeed, much of the so-called affordable housing built in the city over the last two years opts out of the affordable housing requirement. Millions are being made, to a great extent by non-Boulder residents, by selling off beautiful downtown and neighborhood space.
