Community Design for Climate Change | Alan Plattus | TEDxNatick


so the weather of the world is changing

in case you hadn’t noticed and in case

you hadn’t noticed it’s probably not

getting better as the weather gets worse

and worse and as our relationship with

our most precious natural resource not

oil water as it gets more and more

extreme so we have too much water or too

little water and now often in the same

place as storms get more severe and less

predictable a word that you’re going to

be hearing more and more often from

planners policy officials well some

policy officials

it is resilience what does it mean to be

resilient now it turns out that we

really like our superheroes to be

resilient a classic superhero

like my friend Hercules here suffers

near-death experiences but bounces back

stronger than ever to accomplish

incredible feats and conquer monsters

that’s the superhero almost everyone

archetype Lee but what does it mean for

a city for a community for a region to

be resilient notoriously complex as

cities are and often more like the

monster than the superhero well it turns

out that throughout history great cities

have exhibited incredible resilience

multiple times the city of London the

historic heart of London burnt almost

completely to the ground in four days in

September of 1666 and less than a

century later like the superhero it was

back bigger and better than ever already

one of the biggest cities that the world

had ever known and destined for further

industrial and Imperial greatness London

it turns out was getting to the top of

its game and so was naturally resilient

but when Hurricane Katrina in August of

2005 hit the Gulf Coast after

devastating the Caribbean it was a

somewhat different story in cities like

Biloxi and notoriously New Orleans what

that catastrophe did was not to reveal

the hidden strength the resilience of a

community but to expose for all the sea

in their rawness the underlying strata

the inequality the injustice the unmet

challenges of a particular community so

seven years later Hurricane sandy

dealt another blow this time to the most

populous and arguably critical region of

the United States the Northeast and it

is often said in the disaster response

business that it takes not one but two

catastrophes for everybody to finally

sit up and take notice and of course it

doesn’t hurt to flood lower Manhattan it

tends to get certain people’s attention

suddenly we were having at a more urgent

level a conversation that was quietly

going on for a very long time the

awareness of how much of the world’s

population how much of the world’s

critical infrastructure how much of our

resources human and otherwise was

concentrated heavily in the coastal

areas of the world and this was true par

excellence along our own Northeast

Corridor if you didn’t actually live on

the coast you were an armed most likely

totally dependent on power structures

transportation structures health

services that are heavily concentrated

along that coast so we’re all in this

situation together and images like this

started to show up for cities around the

world projecting how much of the cities

that we know the communities that we

inhabit would be flooded in the case of

that dreaded hypothetical hundred year

storm now our response was hard

wired into our culture since the

industrial era we’ve tended to treat big

problems with even bigger solutions if

we can build a bridge between Staten

Island and queens can’t we build a flood

barrier that keeps out that storm surge

well this is our natural response but

once upon a time

traditional civilizations had a more

balanced relationship with water and its

vagaries ancient Egypt the source of

nourishment the source of fertility was

of course the seasonal flooding of the

Nile River it was both a threat but also

a blessing in Venice even today when the

acqua alta comes the high water they

simply get out the temporary walkways

and tourists and local residents keep

their feet dry for as long as the water

is in the Piazza but in most of the

world certainly in recent years the

instinct is to punish the bad water to

put the river in prison after the flood

to build levees to build flood walls to

build big infrastructure that attempts

at least to make the problem go away to

make it so that when we wake up the next

morning we feel safe again we feel

protected the water is out of mind and

largely by the way out of sight as well

and then it fails and suddenly we wake

up to the devastating interconnectedness

of all these systems healthcare

emergency services transportation the

lights that we read by that fuel are

increasingly electronic and digital life

so when in 2012 the lights went off in

New York they at least temporarily went

on in Washington DC and then Secretary

of Housing and Urban Development Shaun

Donovan with the support of the former

dutch director of spatial planning and

water management it’s a Dutch thing

announced and launched a program a

competition actually challenging the

design professions architecture

Landscape Architecture planning

engineering to come up with innovative

solutions promoting resilience real

resilience not by just rebuilding and

responding to the latest catastrophe but

actually dynamically putting in place

innovative ideas that anticipated and

provided for the next one that

competition ran for part of a year I was

a member of a team that submitted a

proposal the proposals were exhibited

and judged and then some of them were in

fact actually funded not at a level that

would make that kind of storm event an

entirely survivable thing but in an

appropriately experimental mode not

surprisingly the biggest funding went to

the New York region which had been so

hard hit by Sandy and to some extent the

Jersey Shore and the most press

attention went to the big engineering

solutions of course how about building a

set of new barrier island

across New York Harbor spectacular how

about building an architectural II

active wall of new cultural institutions

around lower Manhattan in spiral the

problem is that cities like New York

lower Manhattan largely take care of

themselves Chicago for example wykel

London in a previous century burnt to

the ground completely in 1871 but within

two decades the city was back bigger and

better than ever

why because again it had built into it

the essential ingredients of resilience

not just protection from fires or storms

but a robust economy an entrepreneurial

community social and civic institutions

which responded in a proactive and

positive way all of those things

lower Manhattan will take care of itself

eventually it is it has exhibited

extraordinary and inspiring resilience

in the face as you know of very dramatic

catastrophes in recent years but what

about a city like Bridgeport Connecticut

which before it ever got hit by

Hurricane Irene in 2011 and then sandy

again in 2012 had suffered the biggest

catastrophe of all deindustrialization

loss of its economic base loss of its

sense of identity built around industry

and innovation gone and then to add

insult to injury it finds itself one of

the poorest cities in the United States

smack in the middle of one of the

richest economies

one of the richest counties now those of

you who have commercial or residential

real estate experience can do the back

of the envelope map when trouble comes

when you have to respond or rebuild

who’s going to take care of themselves

and who needs outside assistance so

Bridgeport’s storms like New Orleans

storms revealed underlying stresses and

when we started to study the problem it

got even more dramatic this is the

hundred year flood map and you can see

how much of Bridgeport in a 12 foot

surge and you see our friend there

leaning against the elevation indicator

in the South End neighborhood where

we’re working how much of it is really

vulnerable and exposed beautiful little

apparently stable but in fact quite

marginal and delicate and fragile

residential enclaves like seaside

village periodically flood in fact it

turns out that seaside village beautiful

as it is was built on landfill as

emergency wartime workers housing in the

First World War and when it rains or

storms seaside village gets it from

every direction it gets it from the

ocean it gets it from the creek it gets

it from the sky of course and the upland

water that’s coming down on it but it

also gets it from below it has a high

water table it’s built on a very soft

fill so flooding is not just a simple

problem of stopping the storm it’s a

comprehensive problem and it turns out

that cities had a kind of native

intelligence if you look at all maps at

places like Bridgeport and New Orleans

surprise people built on the high ground

not in the salt marshes we’ve only done

that

in the 20th and continuing into the 21st

century so it seems natural to say well

just retreat to the high ground of

course if you don’t already live on the

low ground like so many of the

challenged residents of Bridgeport and

other coastal communities the other

natural response which is wonderful if

you have the resources is build the big

wall it’s not just immigrants build the

Dutch style wall now we’ve learned a lot

from the Dutch but in North America with

our thousands of miles of complicated

coastline our diverse communities are

political disagreements think about the

politics of coastal protection and

recent political events the coasts the

middle of the country the coasts that

solution is not at least immediately

available to us and so as we began work

in Bridgeport we had a much softer idea

an idea that was about adaptation and

evolution rather than fortification and

resistance it was forced upon us by the

reality of the situation by economic

necessity by the limited amount of

resources that we were working with but

also by the nature of the place one of

the south ends great assets was a

beautiful 1867 Olmstead Park homesteads

only Waterfront Park Seaside Park which

had been extended over time to two and a

half miles of coastal public land this

was a natural buffer what we said to

ourselves if we could take that green

edge and extend it over time

comprehensively

to protect and buffer from wave surge

as much of the complicated coastline of

a city like Bridgeport as possible what

if we could even extend it into the

neighborhoods as a system of new public

space and parks that managed water both

stormwater and water from surge that

manage that rather than simply trying to

resist it it’s a complicated system and

like any complicated design it’s not at

its most effective and particularly not

at its most resilient when it’s somebody

else’s project so this kind of work we

think of necessity and by its very

nature involves community engagement

involves listening to the local

community but in the long run involves

empowering the local community because

they are the ones who are going to have

to live going forward and manage going

forward and take ownership of a new

landscape designed now not just to

resist storms and water and catastrophe

but to respond to it dynamically to

manage it to store it for when in dry

periods we actually need it and that

operates at a number of very local

scales water now is something that we

don’t simply put into pipes out of sight

out of mind

or fence off with gigantic pieces of

engineering but they we manage at all

levels through new kinds of public space

through new kinds of streets that hold

and manage water rather than simply

immediately deposit it into our

overburden storm sewer systems and even

in our own backyards this is a an

approach which operates and a number of

different scale

that need like the storms and their

damage itself to interact in complex and

as I’ve said dynamic ways at the

neighborhood scale certainly it’s local

communities that need to understand now

the specific threats and vulnerabilities

and risks that they face but also at the

scale of the region we’re all in this

together particularly in New England

we’re all part of a large and complex

coastal system at the end of the day

whether we like it or not the tide is

rising these big storms are coming again

they will most certainly come thank you
