Coastal Communities Moving to "Form-Based" Zoning Codes
~
Most zoning rules in America are what the zoning geeks like
to call "Euclidian." They're based on flat geometry, and they
divide communities up based on permitted uses: manufacturing
goes here, housing goes there, shopping goes in some other
place.
But critics say that method is one of the major causes of
sprawl - probably the biggest cause, and maybe even the only
cause. It's because cities, towns, and counties won't let you
build houses near shopping or workplaces, and vice versa, they
argue, that the U.S. has turned into a patchwork of suburban
subdivisions, shopping malls, and industrial parks that empty
out at night.
The counter-movement to that sprawl phenomenon is called
"New Urbanism," and the New Urbanists have a different kind of
zoning in mind: "Form-Based Codes." Writer Nate Berg explains
in Architect magazine
("
Brave New Codes," by Nate Berg): "Instead of focusing only
on the separation of types of land uses, form-based codes are
organized around the physical form that a development should
take. Under the guidance of a regulating plan, form-based codes
emphasize connectivity between buildings, their facades, and
the public realm, and how those connections play out across
variously scaled streets and blocks." (Architect is published
by Hanley Wood, which also publishes this newsletter.)
And maybe it’s because sprawl can be most upsetting
when it affects a scenic coastal environment, but form-based
codes seem to be catching on the quickest in coastal cities and
towns. Miami, Florida’s
“
Miami21”
code is one of the largest and best-known efforts at creating a
large-scale form-based code. But other Florida communities of
all sizes, from
Tampa to little
Winter Springs, are also on the bandwagon.
At the
Form-Based Codes
Institute, researchers Hazel Borys and Emily Talen are
keeping track of communities adopting form-based codes. So far
they have a total of 332 examples. And if you include
California on the West Coast, the top eight states on the list
are all coastal states. Florida tops the list with 51 examples,
followed by California with 40. Then it's Texas (33), North
Carolina (17), Mississippi (16), South Carolina (14), Virginia
and Georgia (13 each).
The movement is led by academics and architects, so
it’s no surprise that the language tends to be
abstract, if not impenetrable. For a more down-to-earth
explanation, however, you could turn to the words of Mayor
Billy Keyserling of Beaufort, South Carolina, where the Island
Packet reports that officials, consultants, and townsfolk are
hard at work on a form-based code
(“
New zoning idea rejects car-based communities,” by
Juliann Vachon).
In an editorial for the Island Packet
(
“New urbanism can bring back best of Beaufort's good
old days”), Keyserling painted this picture of the
Beaufort of his childhood: “I rode my bike downtown to
the movies on Bay Street. On the way to and from the movies I
saw three pharmacies, three grocery stores, five clothing
stores, two five-and-dime stores and three hardware stores.
There were, of course, barber and beauty shops and a
shoe-repair shop. There were four service stations, some
restaurants and small businesses on Charles, Bay, Scott, Port
Republic, West, Carteret and Boundary streets. In short,
nothing was more than a few minutes away.”
Form-based zoning, wrote Keyserling, is the effort to make
that world of the past a working archetype for the future.
Wrote the Mayor: “For those who want a feel for what
form-based code might bring, I suggest a leisurely stroll
through downtown. Note that, we have street grids in which
roadways end to meet public space along the Beaufort River. We
have sidewalks, a few remaining service alleys and beautiful,
tree-lined streets. We have houses built a little closer
together, with large private yards replaced by refurbished or
new public parks. Now imagine all of the vacant spaces filled
with businesses run by people who lived downtown and patronized
by people who could work, dine and shop downtown. You would see
a vibrant downtown again bordered by the Beaufort River on
three sides and Battery Creek on the fourth side, not just Bay
Street. Corner markets, bike shops, beauty parlors, small and
large stores, a larger variety of restaurants -- they all would
be part of this vision.”
