While concluding my recent cogitations on the
alternative SMART station site for Petaluma, I offered some thoughts about the
future of urban growth.
I suggested
that (1) if a city has grown outward to a firm urban growth boundary, (2) if the
city has also grown upwards to conform to a reasonable development transect,
and (3) if the demand for housing nonetheless remains high, then the next
solution could be to create well-bounded pockets of urbanism at a distance from
the city, far enough away for the new communities to have separate identities,
but close enough for transit connections to the original city to be effective.
In the
earlier post, I recounted an anecdote about proposing that type of development
for Tolay Lake Park southeast of Petaluma.
In a subsequent email exchange with a North Bay architect, I acknowledged
that a more likely location for development springing outwards from Petaluma
would be around the existing west county communities of Valley Ford or
Bloomfield, or perhaps around the Coast Guard training center in Two Rock.
In essence,
I was proposing islands of urbanism surrounded by land that would remain in its
native or agricultural state.
Thus, I was pleasantly
surprised to learn that Amsterdam was following exactly that path, down to a
literal interpretation of “islands”.
Finding that
new sites for residential development on the mainland were too far away to be effectively
integrated into the metropolis, Amsterdam turned its attention to the adjoining
Lake Ijmeer. The resulting plan, which is now being implemented,
calls for ten new islands to be constructed in the lake, all of which would be
well-filled with residential development and connected to the core of Amsterdam
by tram. (The photo is of the early
development on the lake and is from the linked City Labs article on the project.)
I think the concept is inspired and will be eager
for updates.
But that
doesn’t mean that I’d propose it for the Bay Area. As much as I love the redevelopment proposed
for Treasure Island and expect that it will be an exceptional place to live, I
don’t think that it would possible to replicate the filling of Treasure Island
today. One, I’m not sure that it would
be a good idea environmentally. Two,
even if an environmentally sound concept could be conceived, I doubt it could
be approved through the CEQA process, where even good ideas often go to die.
But even if the
concept of actual islands may not have application to the Bay Area, the concept
of well-defined compact new communities of moderate density remains a valid
model. We may still be years away from
truly needing those new communities, but that means that we can watch and learn
from the Amsterdam experience. I’m intrigued
by the idea of “islands” of urbanism surrounded by farm land.
Next time, I’ll
write of a data point on the financial viability of cities across which I first
stumbled while chatting with the barkeep in a suburban Pittsburgh pub.
As always,
your questions or comments will be appreciated.
