Freedom from cars, freedom from sprawl, freedom to walk your city! City planner Jeff Speck shares his "general theory of walkability" -- four planning principles to transform sprawling cities of six-lane highways and 600-foot blocks into safe, walkable oases full of bike lanes and tree-lined streets.

So I'm here to talk to you
about the walkable city.
0

2889
00:15
What is the walkable city?
1
3810
1359
00:17
Well, for want of a better definition,
2
5193
2481
00:19
it's a city in which the car
is an optional instrument of freedom,
3
7698
6888
00:26
rather than a prosthetic device.
4
14610
1884
00:28
And I'd like to talk about
why we need the walkable city,
5
16518
2955
00:31
and I'd like to talk about
how to do the walkable city.
6
19497
4158
00:35
Most of the talks I give these days
are about why we need it,
7
23679
4340
00:40
but you guys are smart.
8
28043
3096
00:44
And also I gave that talk
exactly a month ago,
9
32314
3247
00:47
and you can see it at TED.com.
10
35585
2067
00:49
So today I want to talk
about how to do it.
11
37676
3000
00:52
In a lot of time thinking about this,
12
40700
1939
00:54
I've come up with what I call
the general theory of walkability.
13
42663
3100
00:57
A bit of a pretentious term,
it's a little tongue-in-cheek,
14
45787
2930
01:00
but it's something
I've thought about for a long time,
15
48741
2574
01:03
and I'd like to share
what I think I've figured out.
16
51339
3384
01:06
In the American city,
the typical American city --
17
54747
2839
01:09
the typical American city
is not Washington, DC,
18
57610
2240
01:11
or New York, or San Francisco;
19
59874
2308
01:14
it's Grand Rapids or Cedar
Rapids or Memphis --
20
62206
3247
01:17
in the typical American city
in which most people own cars
21
65477
3111
01:20
and the temptation
is to drive them all the time,
22
68612
2321
01:22
if you're going to get them to walk,
then you have to offer a walk
23
70957
3779
01:26
that's as good as a drive or better.
24
74760
1848
01:28
What does that mean?
25
76632
1151
01:29
It means you need to offer
four things simultaneously:
26
77807
2541
01:32
there needs to be a proper reason to walk,
27
80372
2057
01:34
the walk has to be safe and feel safe,
28
82453
2350
01:36
the walk has to be comfortable
29
84827
1695
01:38
and the walk has to be interesting.
30
86546
1769
01:40
You need to do all four
of these things simultaneously,
31
88339
2610
01:42
and that's the structure of my talk today,
32
90973
2030
01:45
to take you through each of those.
33
93027
1629
01:46
The reason to walk
is a story I learned from my mentors,
34
94680
3264
01:49
Andrés Duany and Elizabeth Plater-Zyberk,
35
97968
2360
01:52
the founders of the New Urbanism movement.
36
100352
2001
01:54
And I should say half the slides
and half of my talk today
37
102377
3513
01:57
I learned from them.
38
105914
1326
01:59
It's the story of planning,
39
107264
1779
02:01
the story of the formation
of the planning profession.
40
109067
3240
02:04
When in the 19th century
people were choking
41
112331
4751
02:09
from the soot of the dark, satanic mills,
42
117106
2493
02:11
the planners said, hey, let's move
the housing away from the mills.
43
119623
4376
02:16
And lifespans increased
immediately, dramatically,
44
124023
3467
02:19
and we like to say
45
127514
1151
02:20
the planners have been trying to repeat
that experience ever since.
46
128689
3192
02:23
So there's the onset
of what we call Euclidian zoning,
47
131905
2642
02:26
the separation of the landscape
into large areas of single use.
48
134571
4075
02:30
And typically when I arrive
in a city to do a plan,
49
138670
2477
02:33
a plan like this already awaits me
on the property that I'm looking at.
50
141171
4039
02:37
And all a plan like this guarantees
51
145234
1702
02:38
is that you will not have a walkable city,
52
146960
2039
02:41
because nothing is located
near anything else.
53
149023
2920
02:43
The alternative, of course,
is our most walkable city,
54
151967
3640
02:47
and I like to say, you know,
this is a Rothko,
55
155631
2530
02:50
and this is a Seurat.
56
158185
1503
02:51
It's just a different way --
he was the pointilist --
57
159712
2541
02:54
it's a different way of making places.
58
162277
1833
02:56
And even this map of Manhattan
is a bit misleading
59
164134
2809
02:58
because the red color
is uses that are mixed vertically.
60
166967
4180
03:03
So this is the big story
of the New Urbanists --
61
171171
2704
03:05
to acknowledge that there
are only two ways
62
173899
2512
03:08
that have been tested by the thousands
63
176435
2290
03:10
to build communities,
in the world and throughout history.
64
178749
2940
03:13
One is the traditional neighborhood.
65
181713
1878
03:15
You see here several neighborhoods
of Newburyport, Massachusetts,
66
183615
3414
03:19
which is defined as being compact
and being diverse --
67
187053
4267
03:23
places to live, work, shop,
recreate, get educated --
68
191344
4142
03:27
all within walking distance.
69
195510
1879
03:29
And it's defined as being walkable.
70
197413
2136
03:31
There are lots of small streets.
71
199573
1534
03:33
Each one is comfortable to walk on.
72
201131
1726
03:34
And we contrast that to the other way,
73
202881
2514
03:37
an invention that happened
after the Second World War,
74
205419
2819
03:40
suburban sprawl,
75
208262
1258
03:41
clearly not compact, clearly not diverse,
and it's not walkable,
76
209544
4577
03:46
because so few of the streets connect,
77
214145
1898
03:48
that those streets that do connect
become overburdened,
78
216067
2883
03:50
and you wouldn't let your kid out on them.
79
218974
2090
03:53
And I want to thank Alex Maclean,
the aerial photographer,
80
221088
2851
03:55
for many of these beautiful pictures
that I'm showing you today.
81
223963
3055
03:59
So it's fun to break sprawl down
into its constituent parts.
82
227042
3620
04:02
It's so easy to understand,
83
230686
1577
04:04
the places where you only live,
the places where you only work,
84
232287
3003
04:08
the places where you only shop,
85
236144
1956
04:10
and our super-sized public institutions.
86
238124
3344
04:13
Schools get bigger and bigger,
87
241492
1440
04:14
and therefore, further
and further from each other.
88
242956
2396
04:17
And the ratio of the size
of the parking lot
89
245376
3129
04:20
to the size of the school
90
248529
1216
04:21
tells you all you need to know,
91
249769
1616
04:23
which is that no child
has ever walked to this school,
92
251409
2538
04:25
no child will ever walk to this school.
93
253971
1905
04:27
The seniors and juniors are driving
the freshmen and the sophomores,
94
255900
3840
04:31
and of course we have
the crash statistics to prove it.
95
259764
2624
04:34
And then the super-sizing
of our other civic institutions
96
262412
3468
04:37
like playing fields --
97
265904
1170
04:39
it's wonderful that Westin
in the Ft. Lauderdale area
98
267098
3873
04:42
has eight soccer fields
and eight baseball diamonds
99
270995
3068
04:46
and 20 tennis courts,
100
274087
1859
04:47
but look at the road
that takes you to that location,
101
275970
3612
04:51
and would you let your child bike on it?
102
279606
1946
04:53
And this is why we have
the soccer mom now.
103
281576
2130
04:55
When I was young, I had one soccer field,
104
283730
2242
04:57
one baseball diamond and one tennis court,
105
285996
2025
05:00
but I could walk to it,
because it was in my neighborhood.
106
288045
2858
05:02
Then the final part of sprawl
that everyone forgot to count:
107
290927
2851
05:05
if you're going to separate everything
from everything else
108
293802
2820
05:08
and reconnect it
only with automotive infrastructure,
109
296646
2534
05:11
then this is what your landscape
begins to look like.
110
299204
2522
05:13
The main message here is:
111
301750
1215
05:14
if you want to have a walkable city,
you can't start with the sprawl model.
112
302989
3602
05:18
you need the bones of an urban model.
113
306615
2071
05:20
This is the outcome
of that form of design,
114
308710
2848
05:23
as is this.
115
311582
1391
05:24
And this is something
that a lot of Americans want.
116
312997
2589
05:27
But we have to understand
it's a two-part American dream.
117
315610
2713
05:30
If you're dreaming for this,
118
318347
1360
05:31
you're also going to be dreaming of this,
often to absurd extremes,
119
319731
3381
05:35
when we build our landscape
to accommodate cars first.
120
323136
2617
05:37
And the experience
of being in these places --
121
325777
2241
05:40
(Laughter)
122
328042
1017
05:41
This is not Photoshopped.
123
329083
1380
05:42
Walter Kulash took this slide.
124
330487
2002
05:44
It's in Panama City.
125
332513
1697
05:46
This is a real place.
126
334234
1789
05:48
And being a driver
can be a bit of a nuisance,
127
336047
2479
05:50
and being a pedestrian
can be a bit of a nuisance
128
338550
2465
05:53
in these places.
129
341039
1501
05:54
This is a slide that epidemiologists
have been showing for some time now,
130
342564
3474
05:58
(Laughter)
131
346062
1016
05:59
The fact that we have a society
where you drive to the parking lot
132
347102
3465
06:02
to take the escalator to the treadmill
133
350591
1874
06:04
shows that we're doing something wrong.
134
352489
1928
06:06
But we know how to do it better.
135
354441
1572
06:08
Here are the two models contrasted.
136
356037
1683
06:09
I show this slide,
137
357744
1155
06:10
which has been a formative document
of the New Urbanism now
138
358923
2786
06:13
for almost 30 years,
139
361733
1404
06:15
to show that sprawl and the traditional
neighborhood contain the same things.
140
363161
4159
06:19
It's just how big are they,
141
367344
1386
06:20
how close are they to each other,
142
368754
1599
06:22
how are they interspersed together
143
370377
1675
06:24
and do you have a street network,
rather than a cul-de-sac
144
372076
2917
06:27
or a collector system of streets?
145
375017
2035
06:29
So when we look at a downtown area,
146
377076
1817
06:30
at a place that has a hope
of being walkable,
147
378917
2135
06:33
and mostly that's our downtowns
in America's cities
148
381076
2558
06:35
and towns and villages,
149
383658
1768
06:37
we look at them and say
we want the proper balance of uses.
150
385450
3065
06:40
So what is missing or underrepresented?
151
388539
2135
06:42
And again, in the typical American cities
in which most Americans live,
152
390698
3660
06:46
it is housing that is lacking.
153
394382
2010
06:48
The jobs-to-housing balance is off.
154
396416
2190
06:50
And you find that when
you bring housing back,
155
398630
2183
06:52
these other things start to come back too,
156
400837
2066
06:54
and housing is usually first
among those things.
157
402927
2476
06:57
And, of course, the thing
that shows up last and eventually
158
405427
3104
07:00
is the schools,
159
408555
1181
07:01
because the people have to move in,
160
409760
2320
07:04
the young pioneers have to move in,
get older, have kids
161
412104
4821
07:08
and fight, and then the schools
get pretty good eventually.
162
416949
3038
07:12
The other part of this part,
163
420011
2302
07:14
the useful city part,
164
422337
3491
07:17
is transit,
165
425852
1305
07:19
and you can have a perfectly
walkable neighborhood without it.
166
427181
3365
07:22
But perfectly walkable cities
require transit,
167
430570
3305
07:25
because if you don't have access
to the whole city as a pedestrian,
168
433899
3441
07:29
then you get a car,
169
437364
1161
07:30
and if you get a car,
170
438549
1155
07:31
the city begins to reshape itself
around your needs,
171
439728
2548
07:34
and the streets get wider
and the parking lots get bigger
172
442300
2682
07:37
and you no longer have a walkable city.
173
445006
1877
07:38
So transit is essential.
174
446907
1155
07:40
But every transit experience,
every transit trip,
175
448086
2401
07:42
begins or ends as a walk,
176
450511
1895
07:44
and so we have to remember to build
walkability around our transit stations.
177
452430
3798
07:48
Next category, the biggest one,
is the safe walk.
178
456252
2745
07:51
It's what most walkability
experts talk about.
179
459021
2216
07:53
It is essential, but alone not enough
to get people to walk.
180
461261
4041
07:57
And there are so many moving parts
that add up to a walkable city.
181
465326
3143
08:00
The first is block size.
182
468493
1576
08:02
This is Portland, Oregon,
183
470093
1347
08:03
famously 200-foot blocks,
famously walkable.
184
471464
3566
08:07
This is Salt Lake City,
185
475054
1318
08:08
famously 600-foot blocks,
186
476396
2080
08:10
famously unwalkable.
187
478500
1369
08:11
If you look at the two,
it's almost like two different planets,
188
479893
3006
08:14
but these places were both built by humans
189
482923
2316
08:17
and in fact, the story is that when
you have a 200-foot block city,
190
485263
3640
08:20
you can have a two-lane city,
191
488927
1534
08:22
or a two-to-four lane city,
192
490485
1417
08:23
and a 600-foot block city
is a six-lane city, and that's a problem.
193
491926
4025
08:27
These are the crash statistics.
194
495975
1478
08:29
When you double the block size --
195
497477
2086
08:31
this was a study
of 24 California cities --
196
499587
2033
08:33
when you double the block size,
197
501644
1492
08:35
you almost quadruple
the number of fatal accidents
198
503160
3626
08:38
on non-highway streets.
199
506810
2001
08:40
So how many lanes do we have?
200
508835
2231
08:43
This is where I'm going to tell you
what I tell every audience I meet,
201
511090
3477
08:46
which is to remind you
about induced demand.
202
514591
2730
08:49
Induced demand applies
both to highways and to city streets.
203
517345
4437
08:53
And induced demand tells us
that when we widen the streets
204
521806
3485
08:57
to accept the congestion
that we're anticipating,
205
525315
3098
09:00
or the additional trips
that we're anticipating
206
528437
2337
09:02
in congested systems,
it is principally that congestion
207
530798
3913
09:06
that is constraining demand,
208
534735
1993
09:08
and so that the widening comes,
209
536752
1762
09:10
and there are all of these latent trips
that are ready to happen.
210
538538
3116
09:13
People move further from work
211
541678
1389
09:15
and make other choices
about when they commute,
212
543091
2233
09:17
and those lanes fill up
very quickly with traffic,
213
545348
2374
09:19
so we widen the street again,
and they fill up again.
214
547746
2501
09:22
And we've learned that
in congested systems,
215
550271
2226
09:24
we cannot satisfy the automobile.
216
552521
2415
09:26
This is from Newsweek Magazine --
hardly an esoteric publication:
217
554960
3450
09:30
"Today's engineers acknowledge
218
558434
1668
09:32
that building new roads
usually makes traffic worse."
219
560126
3226
09:35
My response to reading this was,
may I please meet some of these engineers,
220
563376
3563
09:38
because these are not the ones that I --
221
566963
2066
09:41
there are great exceptions
that I'm working with now --
222
569053
2590
09:43
but these are not the engineers
one typically meets working in a city,
223
571667
3306
09:46
where they say, "Oh, that road
is too crowded, we need to add a lane."
224
574997
3466
09:50
So you add a lane, and the traffic comes,
225
578487
2160
09:52
and they say, "See, I told you
we needed that lane."
226
580671
2457
09:55
This applies both to highways
and to city streets if they're congested.
227
583152
3792
09:58
But the amazing thing
about most American cities that I work in,
228
586968
3035
10:02
the more typical cities,
229
590027
1289
10:03
is that they have a lot of streets
that are actually oversized
230
591340
3032
10:06
for the congestion
they're currently experiencing.
231
594396
2407
10:08
This was the case in Oklahoma City,
232
596827
1723
10:10
when the mayor came running
to me, very upset,
233
598574
2519
10:13
because they were named
in Prevention Magazine
234
601117
2404
10:15
the worst city for pedestrians
in the entire country.
235
603545
3153
10:18
Now that can't possibly be true,
236
606722
1706
10:20
but it certainly is enough
to make a mayor do something about it.
237
608452
3129
10:23
We did a walkability study,
238
611605
1309
10:24
and what we found, looking
at the car counts on the street --
239
612938
3335
10:28
these are 3,000-, 4,000-, 7,000-car counts
240
616297
3675
10:31
and we know that two lanes
can handle 10,000 cars per day.
241
619996
3947
10:35
Look at these numbers --
they're all near or under 10,000 cars,
242
623967
4657
10:40
and these were the streets
that were designated
243
628648
2574
10:43
in the new downtown plan
244
631246
2212
10:45
to be four lanes to six lanes wide.
245
633482
2634
10:48
So you had a fundamental disconnect
between the number of lanes
246
636140
3245
10:51
and the number of cars
that wanted to use them.
247
639409
2242
10:53
So it was my job to redesign
every street in the downtown
248
641675
3915
10:57
from curb face to curb face,
249
645614
1735
10:59
and we did it for 50 blocks of streets,
250
647373
2002
11:01
and we're rebuilding it now.
251
649399
1357
11:02
So a typical oversized street to nowhere
252
650780
3040
11:05
is being narrowed, and now
under construction,
253
653844
2200
11:08
and the project is half done.
254
656068
1640
11:09
The typical street like this, you know,
255
657732
1991
11:11
when you do that,
you find room for medians.
256
659747
3446
11:15
You find room for bike lanes.
257
663217
1982
11:17
We've doubled the amount
of on-street parking.
258
665223
2167
11:19
We've added a full bike network
where one didn't exist before.
259
667414
3949
11:23
But not everyone has the money
that Oklahoma City has,
260
671387
3247
11:26
because they have an extraction
economy that's doing quite well.
261
674658
3084
11:29
The typical city is more
like Cedar Rapids,
262
677766
2052
11:31
where they have an all four-lane
system, half one-way system.
263
679842
3990
11:35
And it's a little hard to see,
264
683856
1449
11:37
but what we've done -- what we're doing;
it's in process right now,
265
685329
3284
11:40
it's in engineering right now --
266
688637
1604
11:42
is turning an all four-lane
system, half one-way
267
690265
3791
11:46
into an all two-lane system, all two-way,
268
694080
3577
11:49
and in so doing, we're adding
70 percent more on-street parking,
269
697681
3241
11:52
which the merchants love,
270
700946
1359
11:54
and it protects the sidewalk.
271
702329
1420
11:55
That parking makes the sidewalk safe,
272
703773
1762
11:57
and we're adding a much more
robust bicycle network.
273
705559
3678
12:01
Then the lanes themselves.
How wide are they?
274
709261
2581
12:03
That's really important.
275
711866
1210
12:05
The standards have changed
such that, as Andrés Duany says,
276
713100
3166
12:08
the typical road
to a subdivision in America
277
716290
2094
12:10
allows you to see
the curvature of the Earth.
278
718408
2192
12:12
(Laughter)
279
720624
1039
12:13
This is a subdivision
outside of Washington from the 1960s.
280
721687
3245
12:16
Look very carefully
at the width of the streets.
281
724956
2321
12:19
This is a subdivision from the 1980s.
282
727301
2107
12:21
1960s, 1980s.
283
729432
1635
12:23
The standards have changed
to such a degree
284
731091
2024
12:25
that my old neighborhood of South Beach,
285
733139
1953
12:27
when it was time to fix the street
that wasn't draining properly,
286
735116
3159
12:30
they had to widen it
and take away half our sidewalk,
287
738299
2544
12:32
because the standards were wider.
288
740867
1739
12:34
People go faster on wider streets.
289
742630
3455
12:38
People know this.
290
746109
1157
12:39
The engineers deny it,
but the citizens know it,
291
747290
3126
12:42
so that in Birmingham, Michigan,
they fight for narrower streets.
292
750440
3826
12:46
Portland, Oregon, famously walkable,
293
754290
2522
12:48
instituted its "Skinny Streets" program
in its residential neighborhood.
294
756836
3545
12:52
We know that skinny streets are safer.
295
760405
1850
12:54
The developer Vince Graham,
in his project I'On,
296
762279
3046
12:57
which we worked on in South Carolina,
297
765349
1816
12:59
he goes to conferences and he shows
his amazing 22-foot roads.
298
767189
3915
13:03
These are two-way roads,
very narrow rights of way,
299
771128
2413
13:05
and he shows this well-known philosopher,
300
773565
1999
13:07
who said, "Broad is the road
that leads to destruction ...
301
775588
2870
13:10
narrow is the road that leads to life."
302
778482
2101
13:12
(Laughter)
303
780607
2060
13:14
(Applause)
304
782691
2369
13:17
This plays very well in the South.
305
785084
2059
13:19
Now: bicycles.
306
787167
1897
13:21
Bicycles and bicycling
are the current revolution underway
307
789929
4482
13:26
in only some American cities.
308
794435
1683
13:28
But where you build it, they come.
309
796142
1641
13:29
As a planner, I hate to say that,
but the one thing I can say
310
797807
4009
13:33
is that bicycle population
is a function of bicycle infrastructure.
311
801840
4127
13:37
I asked my friend Tom Brennan
from Nelson\Nygaard in Portland
312
805991
3415
13:41
to send me some pictures
of the Portland bike commute.
313
809430
2580
13:44
He sent me this. I said,
"Was that bike to work day?"
314
812034
2508
13:46
He said, "No, that was Tuesday."
315
814566
1645
13:48
When you do what Portland did and spend
money on bicycle infrastructure --
316
816235
4964
13:53
New York City has doubled the number
of bikers in it several times now
317
821223
4221
13:57
by painting these bright green lanes.
318
825468
2037
13:59
Even automotive cities
like Long Beach, California:
319
827529
3566
14:03
vast uptick in the number of bikers
based on the infrastructure.
320
831119
4079
14:07
And of course, what really does it,
321
835222
1691
14:08
if you know 15th Street
here in Washington, DC --
322
836937
2376
14:11
please meet Rahm Emanuel's
new bike lanes in Chicago,
323
839337
2977
14:14
the buffered lane, the parallel parking
pulled off the curb,
324
842338
3378
14:17
the bikes between the parked
cars and the curb --
325
845740
4002
14:21
these mint cyclists.
326
849766
1921
14:23
If, however, as in Pasadena,
every lane is a bike lane,
327
851711
3551
14:27
then no lane is a bike lane.
328
855286
1961
14:29
And this is the only bicyclist
that I met in Pasadena, so ...
329
857271
3112
14:32
(Laughter)
330
860407
1605
14:34
The parallel parking I mentioned --
331
862036
1691
14:35
it's an essential barrier of steel
332
863751
1622
14:37
that protects the curb and pedestrians
from moving vehicles.
333
865397
3786
14:41
This is Ft. Lauderdale;
one side of the street, you can park,
334
869207
3596
14:44
the other side of the street, you can't.
335
872827
1952
14:46
This is happy hour on the parking side.
336
874803
2025
14:48
This is sad hour on the other side.
337
876852
2691
14:51
And then the trees themselves
slow cars down.
338
879567
2989
14:54
They move slower when trees
are next to the road,
339
882580
2286
14:56
and, of course, sometimes
they slow down very quickly.
340
884890
2555
15:00
All the little details --
the curb return radius.
341
888119
2952
15:03
Is it one foot or is it 40 feet?
342
891095
1662
15:04
How swoopy is that curb to determine
how fast the car goes
343
892781
3446
15:08
and how much room you have to cross.
344
896251
1715
15:09
And then I love this, because this
is objective journalism.
345
897990
3422
15:13
"Some say the entrance to CityCenter
is not inviting to pedestrians."
346
901436
4079
15:17
When every aspect
of the landscape is swoopy,
347
905539
2458
15:20
is aerodynamic, is stream-form geometrics,
348
908021
2673
15:22
it says: "This is a vehicular place."
349
910718
2317
15:25
So no one detail, no one speciality,
can be allowed to set the stage.
350
913059
5075
15:30
And here, you know, this street:
351
918158
1564
15:31
yes, it will drain within a minute
of the hundred-year storm,
352
919746
3892
15:35
but this poor woman
has to mount the curb every day.
353
923662
2792
15:38
So then quickly, the comfortable walk
has to do with the fact
354
926478
2946
15:41
that all animals seek, simultaneously,
prospect and refuge.
355
929448
4953
15:46
We want to be able to see our predators,
356
934425
2100
15:48
but we also want to feel
that our flanks are covered.
357
936549
2519
15:51
And so we're drawn to places
that have good edges,
358
939092
2491
15:53
and if you don't supply the edges,
people won't want to be there.
359
941607
3328
15:56
What's the proper ratio
of height to width?
360
944959
2139
15:59
Is it one to one? Three to one?
361
947122
1775
16:00
If you get beyond one to six,
you're not very comfortable anymore.
362
948921
3785
16:04
You don't feel enclosed.
363
952730
1319
16:06
Now, six to one in Salzburg
can be perfectly delightful.
364
954073
3145
16:09
The opposite of Salzburg is Houston.
365
957242
2387
16:12
The point being the parking lot
is the principal problem here.
366
960487
3600
16:16
However, missing teeth, those empty lots
can be issues as well,
367
964111
3575
16:19
and if you have a missing corner
because of an outdated zoning code,
368
967710
3245
16:22
then you could have a missing nose
in your neighborhood.
369
970979
2908
16:25
That's what we had in my neighborhood.
370
973911
1837
16:27
This was the zoning code that said
I couldn't build on that site.
371
975772
3076
16:30
As you may know, Washington, DC
is now changing its zoning
372
978872
3727
16:34
to allow sites like this
to become sites like this.
373
982623
3130
16:37
We needed a lot of variances to do that.
374
985777
2166
16:39
Triangular houses
can be interesting to build,
375
987967
2284
16:42
but if you get one built,
people generally like it.
376
990275
2702
16:45
So you've got to fill those missing noses.
377
993001
2453
16:47
And then, finally, the interesting walk:
378
995478
1958
16:49
signs of humanity.
379
997460
1672
16:51
We are among the social primates.
380
999156
1815
16:52
Nothing interests us more
than other people.
381
1000995
2188
16:55
We want signs of people.
382
1003207
1494
16:56
So the perfect one-to-one ratio,
it's a great thing.
383
1004725
3003
16:59
This is Grand Rapids,
a very walkable city,
384
1007752
2204
17:01
but nobody walks on this street
385
1009980
1642
17:03
that connects the two
best hotels together,
386
1011646
2111
17:05
because if on the left,
you have an exposed parking deck,
387
1013781
4368
17:10
and on the right,
you have a conference facility
388
1018173
2484
17:12
that was apparently designed
in admiration for that parking deck,
389
1020681
3429
17:16
then you don't attract that many people.
390
1024134
2507
17:18
Mayor Joe Riley, in his 10th term,
Mayor of Charleston, South Carolina,
391
1026665
3974
17:22
taught us it only takes
25 feet of building
392
1030663
2177
17:24
to hide 250 feet of garage.
393
1032864
2294
17:27
This one I call the Chia Pet Garage.
It's in South Beach.
394
1035182
2720
17:29
That active ground floor.
395
1037926
1444
17:31
I want to end with this project
that I love to show.
396
1039394
2719
17:34
It's by Meleca Architects.
It's in Columbus, Ohio.
397
1042137
2511
17:36
To the left is the convention center
neighborhood, full of pedestrians.
398
1044672
3690
17:40
To the right is the Short North
neighborhood -- ethnic,
399
1048386
2664
17:43
great restaurants,
great shops, struggling.
400
1051074
2697
17:45
It wasn't doing very well
because this was the bridge,
401
1053795
2554
17:48
and no one was walking
from the convention center
402
1056373
2467
17:50
into that neighborhood.
403
1058864
1349
17:52
Well, when they rebuilt the highway,
they added an extra 80 feet to the bridge.
404
1060237
4293
17:56
Sorry -- they rebuilt the bridge
over the highway.
405
1064554
2474
17:59
The city paid 1.9 million dollars,
406
1067052
2373
18:01
they gave the site to a developer,
407
1069449
2246
18:03
the developer built this
408
1071719
1391
18:05
and now the Short North
has come back to life.
409
1073134
2319
18:07
And everyone says, the newspapers,
not the planning magazines,
410
1075477
3216
18:10
the newspapers say
it's because of that bridge.
411
1078717
2221
18:12
So that's it. That's the general
theory of walkability.
412
1080962
2620
18:15
Think about your own cities.
413
1083606
2020
18:17
Think about how you can apply it.
414
1085650
2417
18:20
You've got to do all four things at once.
415
1088091
1954
18:22
So find those places where you
have most of them
416
1090069
2309
18:24
and fix what you can,
417
1092402
1905
18:26
fix what still needs fixing
in those places.
418
1094331
2684
18:29
I really appreciate your attention,
419
1097039
1768
18:30
and thank you for coming today.
420
1098831
