Urban planning A tool in our equity toolbox

[Applause]

i want you to take a minute and close

your eyes

and think about the neighborhood that

you grew up in

think about your house or apartment the

robes you use

to get to work or to school is there a

grocery store nearby

how about a library or a park within

walking distance

you can open your eyes maybe the

neighborhood you pictured looks like

this or maybe it looked a bit more like

this

or maybe you had a giant freeway running

right through your backyard

no matter where you grew up the

environment you lived in was planned

urban planning has been necessary since

the dawn of modern cities

while good urban planning can keep us

safe and healthy

bad urban planning can decimate

communities and create racial and

economic divides

tonight i want to talk about a few

examples of good and bad urban planning

and how urban planning is now being used

as a tool to overcome these divides that

we have created

here are two urban centers that you

might recognize

on the left is madrid and on the right

is manhattan

both of these cities are characterized

by dense urban cores

without much interruption except for

large green spaces

so you can see parque retiro in madrid

on the left and central park

on the right in the middle of manhattan

now let’s compare these two cities

to some midwestern cities

here on the left is detroit and on the

right is cincinnati

now what’s the obvious difference

between these two cities and the last

two

in detroit and cincinnati and many other

u.s cities

large urban freeways cut through their

downtown cores dividing their

neighborhoods in half

in 1956 when president eisenhower signed

the federal highways act

cities began using federal money to

build freeways through their cities as

quickly

as they could oftentimes these freeway

projects were used for targeted

demolitions for what the cities deemed

as blighted neighborhoods

these blighted neighborhoods were almost

exclusively communities of color

these freeway projects took these

communities of color that were already

disadvantaged and discriminated against

and literally cemented them in it for

decades to come

so let’s look at a real example this is

black bottom detroit

one of the most successful black

neighborhoods in the midwest in the

first half of the 20th century

pictured here is hastings street their

main drag and you can see it is lined by

thriving shops and businesses

it hardly looks like a blighted

neighborhood however the city of detroit

determined

that the priorities of white suburban

commuters were more important than those

of the black detroiters that were living

in that neighborhood

so they decided to level the

neighborhood in preparation for freeway

this is what black bottom looked like

once the freeway was built and this

is what it looks like now black bottom

is interstate 375

one of the least used freeways in the

city of detroit

many of the 50 000 drivers a day do not

know the history of the land that they

drive upon

was all of this destruction for the

scantily used freeway worth it

the obvious answer is no so what are

urban planners doing about it

this is a michigan department of

transportation rendering of the

interstate 375 corridor future plans

they plan to remove the freeway and

replace it with a boulevard and green

space

this freeway removal project will help

to ease the movement of people from

either side of the freeway

increase the land values for the

residents who still remain in that area

increase the visibility for the small

businesses in that area

and reduce traffic noise many

other u.s cities have already carried

out freeway removal projects such as

this

this is a central artery in boston and

until 1993 the central artery carried

large amounts of traffic through

downtown boston

locals called it the distress way or the

other green monster

after the large wall in the outfield of

fenway park because of its notorious

traffic congestion

the city needed to fix this problem what

was their solution

to dig a one and a half mile long tunnel

under the city

known as a project called the big dig

this is what downtown boston looks like

now you can see

they removed the freeway and replaced it

with large urban parks

over top of these new tunnels the

freeway removal project again

increased land values decreased noise at

surface level

fixed the traffic problems and

reconnected downtown boston to its

waterfront

here are two other brief examples on the

left you can see the alaskan way viaduct

in seattle and its subsequent

replacement with a tunnel and on the

right is the removal of the inner loop

freeway in syracuse new york

now there are typically three big

concerns that come up

when considering freeway removal

projects the first

is that the traffic from these freeways

could potentially cascade

into the surrounding neighborhoods

completed projects have shown that this

just isn’t the case

alternate routes and modes such as

cycling and transit are sought out

and local ordinances can be put into

place to prevent cut through traffic

a second big concern is that by removing

these freeways

the land values in the area could

rapidly decrease while on the surface

this doesn’t seem like a major problem

it can cause

problems for residents who have lived

there for decades and all of a sudden

find that they can no longer afford

their rent and are forced to move

a creative solution to this problem is

to create a community land trust

the community land trust would allow the

minority residents

to continue to maintain control of that

reclaimed land

by allowing them to set sail price

limits for the new developments which

would make the development more

sustainable

a third concern is that residents

usually perceive freeway removal as more

disruptive

and more expensive than just

refurbishing the freeways that we

already have

this also is not the case this is the

park east freeway in milwaukee wisconsin

and until 2003 it cut through milwaukee

neighborhoods and carried traffic right

into downtown

but in 2003 it was reaching the end of

its 50-year lifespan

and the city had to decide whether to

remove it or replace and refurbish it

the city decided to remove it and they

determined that it was over five million

dollars cheaper

to remove the freeway than to replace it

and it created over two billion dollars

in economic benefit for the surrounding

community

in other words it was money well spent

for that area

now in addition to freeway removal

projects transit is another big way

that urban planners can create equity in

our communities

transit comes in many different forms

such as elevated rail subway

street cars and more commonly now bus

rapid transit systems with designated

lanes as shown here on the right

transit is often a better solution than

building freeways because it does not

require the

typical mass disruptions that building

freeways can cause

the transit systems can be built on top

of existing infrastructure and

underground

houston and new york show these

differences very well

on the left you can see the katy freeway

in houston and on the right

is the lexington avenue corridor in

manhattan

now at a glance if i were to ask you

which of these two corridors carried

more traffic in a day

you’d probably say the katy freeway in

houston the katy freeway only carries

about three 300 000 people

a day in stop and go traffic the

lexington avenue corridor however

carries over

1.3 million people per day in a

combination of car and bus traffic

cyclists and pedestrians and on four

subway tracks that run beneath the

street

now part of that is because of

development trends

and the population density in houston

those

suburbs in houston just aren’t dense

enough to support the mass transit usage

that midtown manhattan experiences

however if we prioritize

transit development we can shift these

density trends

towards more sustainable communities

transit-oriented development is becoming

increasingly common in the u.s and

around the world

transit oriented development is the

creation of compact

walkable communities that are mixed use

and centered around

high quality transit systems transit

oriented development creates a unique

opportunity

to provide low-income housing the bay

area rapid transit in san francisco

known as bart has partnered with

developers

to develop land that they already own

around their stations and in these

projects they have created low-income

housing units

bart has already created 900 low-income

housing units with their projects in the

past 10 years

and they plan to double that number in

the next 10 years

these projects have been creating equity

for the bay area

by not only ensuring that low-income

residents have housing available to them

but also by connecting them to

high-quality transit systems

that allow them to connect to more

opportunities around the bay area

we should talk about how we define

equity because as a good professor of

mine

will not let me forget the way we use

words matters

now when we talk about equity we usually

think of it

in a sense of equality or impartiality

but when we think about social equity it

goes far beyond our basic concept of

equality so i’m sure many of you have

seen this graphic before

it illustrates the difference between

equality and equity so on the left

three people of the same heights are

given the same size boxes

to try and see over the fence and watch

the baseball game

while two of them can see over the fence

the third by no fault of his own is

still too short to watch the game

a more equitable solution would be to

give them

boxes of different heights so that no

matter where they started out

they can all see the game equally now

you’re probably thinking

this is great and all but what can i do

to make sure that my city becomes a more

equitable place to live

the key is to get involved the urban

planning process relies on listening to

the communities that

urban planners are planning for so if

you get

one thing out of these 10 minutes let it

be this

your participation is essential to

transforming our communities

your opinions matter and your voice

needs to be heard

so i encourage you check out your city’s

website look at what projects they have

in the works

and go to a public hearing give them

your feedback maybe you’ll learn a thing

about local government along the way

infrastructure and urban planning

provides us with a unique opportunity to

change our landscapes for decades to

come

while we have seen how the lasting

impacts of infrastructure can be

negative when planned poorly

good urban planning is one of the most

tangible tools that we have to create

equity in our communities

while our fight against racial economic

and environmental injustice

needs to be aggressively multifaceted

infrastructure is a great

and easy place to start thank you

[掌声]

我要你花点时间

闭上眼睛想想

你长大的社区

想想你的房子或公寓

上班或上学的长袍

附近有杂货店

吗? 图书馆或步行距离内的公园

你可以睁开眼睛 也许

你所描绘的社区

看起来像这样,或者看起来更像

这样,

或者也许你有一条巨大的高速公路

穿过你的后院,

无论你在哪里长大

自现代城市诞生以来,城市规划一直是必要

的,

而良好的城市规划可以保证我们的

安全和健康

糟糕的城市规划今晚会摧毁

社区并造成种族和

经济分歧

我想谈谈

好的和坏的几个例子 城市规划

以及城市规划现在如何被

用作克服我们在这里创造的这些分歧的工具

是您

可能会认识到的两个城市

中心 e 左边是马德里,右边

是曼哈顿

,这两个城市的特点

都是密集的城市核心

,除了大的绿地外没有太多的中断,

所以你可以看到左边是马德里的 parque retiro,

右边是曼哈顿中部的中央公园

现在让我们将这两个城市

与一些中西部

城市进行比较,左边是底特律,

右边是辛辛那提

现在

这两个城市与

底特律和辛辛那提的最后两个城市以及美国其他

许多城市的明显区别是什么?

1956 年,当艾森豪威尔总统签署联邦公路法案时,市中心将他们的社区一分为二,

城市开始使用联邦资金

尽可能快地修建穿过城市的高速公路,

这些高速公路

项目经常被用于有针对性地

拆除被城市

视为破败的社区

这些破败的社区几乎

完全是有色人种的社区

这些高速公路项目

将这些已经

处于不利地位和受歧视的有色人种社区

纳入其中,并在未来几十年内巩固了他们,

所以让我们看一个真实的例子,这是

底特律

黑底,是中西部最成功的黑人

社区

之一 图中所示的 20 世纪上半叶

是黑斯廷斯街,它们的

主要街道,你可以看到它两旁是

繁荣的商店和企业

,看起来不像是一个破败的

社区,但底特律市

确定

白人郊区通勤者的优先事项

比那些更重要

居住在该社区的黑人底特律人中,

因此他们决定将该社区夷为平地,

为高速公路

做准备 这

就是高速公路建成后

黑底的样子,这就是现在的样子 黑底

是 375 号州际公路

,是最不发达的州际公路之一 在底特律市使用高速公路,

每天 50 000 名司机中的许多人不

知道历史 他们开车经过的土地

是所有这些对

很少使用的高速公路的破坏都值得

的显而易见的答案是否定的所以

城市规划者对此做了什么

这是密歇根州

交通部的

375号州际公路走廊

他们计划的未来计划 拆除高速公路并

用林荫大道和绿地取而代之

这个高速公路拆除项目将

有助于缓解高速公路两侧的人员流动

增加

仍然留在该地区

的居民的土地价值

该地区的企业

和减少交通噪音美国许多

其他城市已经开展

了高速公路拆除项目,例如

这是波士顿的中央动脉,

直到 1993 年,中央动脉承载

大量交通通过

波士顿市中心,

当地人称其为遇险路或 由于臭名昭著

的交通,芬威球场外场的大墙之后的另一个绿色怪物

ic

拥堵 城市需要解决这个问题

他们的解决

方案是什么他们在城市地下挖了一个半英里长的隧道

称为大挖掘项目

这就是波士顿市中心

现在的样子 你可以看到

他们拆除了高速公路 取而代之的

是这些新隧道顶部的大型城市公园

高速公路拆除项目再次

增加土地价值 降低地表噪音

解决交通问题并将

波士顿市中心重新连接到其

海滨

这里是左边的另外两个简短示例,

您可以看到阿拉斯加

西雅图的高架桥以及随后

用隧道代替,

右边是拆除

纽约锡拉丘兹的内环高速公路

现在在考虑高速公路拆除项目时通常会出现三个大

问题,

首先

是来自这些的交通 高速公路

可能会延伸

到周围的社区

已完成的项目表明

情况并非如此

寻找替代路线和方式,例如骑自行车和过境,

并制定地方条例

以防止交通中断

第二个大问题是,通过拆除

这些高速公路

,该地区的土地价值可能会

迅速下降,而在表面上

这不会 “这似乎不是一个大问题,

它可能会给

住在那里几十年的居民带来问题

,突然

发现他们再也负担

不起房租,被迫搬家

解决这个问题的创造性解决方案

是创建一个社区土地

相信社区土地信托将允许

少数居民

继续保持对

填海土地

的控制,允许他们

为新开发项目设定价格限制,这

将使开发项目更具

可持续性。

第三个担忧是居民

通常认为拆除高速公路会增加

破坏性

和比仅仅

翻新我们已经拥有的高速公路更昂贵

这也不是我的情况 是

威斯康星州密尔沃基市的公园东高速公路

,直到 2003 年它穿过密尔沃基

社区并将交通直接

输送到市中心,

但在 2003 年,

它的 50 年使用寿命即将结束

,该市不得不决定是

拆除它还是更换和翻新

城市决定拆除它,他们

确定

拆除高速公路比更换它便宜 500 万美元

,它为周围社区创造了超过 20 亿美元

的经济利益

,换句话说,这笔钱花

得值。

现在除了高速公路拆除

项目外,交通

是城市规划者可以在

我们的社区中创造公平的另一种重要方式

交通有许多不同的形式,

例如高架轨道地铁

有轨电车和现在更常见的

带有指定车道的快速公交系统,

如图所示 正确的

交通方式通常是比修建高速公路更好的解决方案,

因为它不需要

典型的大规模破坏 建设

高速公路会

导致交通系统可以建立

在现有基础设施和

地下

的基础

现在一目了然,如果我要问你

这两条走廊中哪一条

在一天内的交通量更大,

你可能会说

休斯顿的凯蒂高速公路 凯蒂高速公路每天只能运送

大约 3300 000

人在走走停停的列

克星敦 然而,大道走廊

每天承载超过 130 万人

,包括汽车和公共汽车交通

骑自行车者和行人,以及在街道

下方运行的四个地铁轨道,

现在部分原因是休斯顿那些郊区的

发展趋势

和人口

密度 只是不够密集,

不足以支持

曼哈顿中城经历的公共交通使用

但是如果我们优先考虑

交通发展 我们能否将这些

密度趋势

转向更可持续的社区 以

公交为导向的发展

在美国和世界各地变得越来越普遍

创造了一个

提供低收入住房的独特机会

旧金山湾区的快速交通公司

bart 与

开发商

合作开发他们在车站周围已经拥有的土地,

并在这些

项目中创建了低收入

住房单元

bart 已经 在过去的 10 年里,他们的项目创造了 900 个低收入

住房单元,他们计划在

未来 10 年内

将这个数字翻一番

他们

还通过将他们连接到

高质量的交通

系统 让他们

与湾区周围的更多机会联系起来,

我们应该谈谈我们如何定义

公平,因为作为我的一位好教授

不会让我忘记我们现在用词的方式很

重要,

当我们谈论公平时,我们通常

在一个 平等或公正的感觉,

但是当我们考虑社会公平时,它

远远超出了我们的基本平等概念,

所以我相信你们中的许多人

它说明

平等和公平之间的区别之前已经看过这张图,所以左边

三个人 相同的高度被

给予相同大小的盒子

来尝试越过栅栏

观看棒球比赛,

而他们中的两个可以越过栅栏看到

第三个不是他自己的过错

仍然太矮而无法观看比赛

一个更公平的解决方案将

给他们

不同高度的盒子,这样

无论他们从哪里开始,

他们都可以平等地看到比赛现在

你可能认为

这很棒,除了我能做些什么

来确保我的 c 城市成为一个更

公平的居住

地 关键是参与 城市

规划过程依赖于倾听

城市规划者正在规划的社区,所以如果

在这 10 分钟内得到一件事,

那就是

你的参与是必不可少的

改变我们的社区

你的意见很重要,你的声音

需要被听到,

所以我鼓励你查看你所在城市的

网站,看看他们

正在进行的项目

并参加公开听证会 给他们

你的反馈也许你会学到一些

关于当地的事情 政府在

基础设施和城市规划的过程中

为我们提供了一个独特的机会来

改变未来几十年的景观,

而我们已经看到基础设施的持久影响如何

在规划不佳时产生负面影响,

良好的城市规划是我们最

切实的工具之一 必须

在我们的社区中创造公平,

而我们与种族经济

和环境不公正的斗争

需要积极进取 ely 多方面的

基础设施是一个伟大

而容易开始的地方谢谢
