An op-ed by Daniel Freedman explains how a legal spat over an 850-square-foot "granny flat" affected hundreds of units around Los Angeles. The city's attempt to rectify the problems with its second unit ordinance has encountered more resistance.
In the 1990s, most public argument about suburban expansion was pretty simple. Environmentalists argued that sprawl increased pollution, while their opponents responded by invoking the free market. Environmentalists and other sprawl critics (including myself) responded that sprawl is the result less of the free market than of government subsidy and regulation.
Recently I have started to notice hints of a not-so-libertarian argument for sprawl: that pro-sprawl government policies such as highway construction open up real estate for development, and thus make housing affordable.
The conventional wisdom among Americans who spend
lots of time thinking about public transit is that four more years of Obama
will be good news, and the election of the Romney-Ryan ticket would be
bad. I have to admit that this belief is
by no means completely irrational: after all, President Romney will be much
less likely than President Obama to veto a transportation bill passed by a
Republican Congress, and might propose a mere austere budget than President Obama. Nevertheless, I
think there are good reasons to believe otherwise.
Decades ago, ecologist Garrett Hardin wrote about the "tragedy of the commons"- when an action that is rational for one person becomes irrational when widely practiced.
For example, suppose that there are a few dozen cattle
ranchers near a pasture open to all.It
makes sense for each rancher to let as many cattle graze as possible on the
pasture, so that the ranchers can feed their cattle without buying additional
land.But if every rancher lets as many
cattle as possible graze, sooner or later the land will be overgrazed and the
cattle may starve.
In the early 1990s, transportation politics at both the state and federal levels was often fairly simple: an all-powerful Road Gang (made up of real estate developers and road contractors) typically got whatever it wanted, rolling over a much weaker pro-transit coalition of environmentalists and urban politicians.
Arguments over transportation policy often run as follows:
HIGHWAY SUPPORTER: Highways pay for themselves! Buses/trains don't! So highways good and everything else bad bad bad!
TRANSIT SUPPORTER: But highways create bad externalities like pollution and climate change! So if highways were taxed at their true cost gas would cost a zillion billion cajillion dollars per gallon!
(followed by numerous counterarguments and counter-counterarguments that I won't bore you with, except as written below...)
It seems to me that these arguments miss one point: even if the highway system as a whole pays for itself, the system is so chock full of cross-subsidies that each individual road doesn't (except for toll roads).
