Dear Steve,

Wish I could make it!

By any chance will you be discussing alternatives to the dominant
asphalt-based construction of streets, as well as their configuration?  I
have been concerned for some time that the current paradigm must change
substantially, in part due to cost.

Some ideas for a new approach to paving *residential* streets:
a. Smooth paving for cycling only (supports traffic calming, allows
traditional/permeable/rough roadways)
b. No paving for parking areas (gravel/stones/permeable concrete squares or
even just dirt instead)
c. Mechanisms for residents to convert roadway to green space
d. Ban heavy vehicles from local streets, they do much damage
e. Creek restoration, street closures, carfree zones.

This in part because I saw recently the San Francisco, CA MPO is spending
1/3 of the budget on streets and admits it can't even maintain current
streets at current investments. Some rural areas have already begun
grinding asphalt up to make instant gravel, rather than repave. I broached
this topic at a major conference ("New Partners for Smart Growth" USA) and
industry folks wouldn't hear of it, and instead emphasized "green asphalt"
which may last longer, but costs more too, and doesn't address the
fundamental issue. Meanwhile, folks might wait even decades for repaving of
streets and they're immediately ripped up for construction, resulting in
bumps and lumps that particularly affect cyclists.

The good news perhaps is the roadway network is shrinking (in the USA, at
least). The bad news is the cycling environment is declining while we
needlessly misallocate resources.

My thought: change the paradigm!

This begets the exciting inquiry of a comparison between choices: cost,
lifespan, effects on users, mechanisms for implementation and financing.
E.g., is it cheaper and healthier to convert a street to a park, or to
repave it?

Anyone game?
