Classifying Open Space: City Squares, Commons and Public Gardens

January 1st, 2009

This is part 2/6 in a series overviewing The Normal Requirements of American Towns and Cities in Respect to Public Open Spaces, an article written by Frederick Law Olmsted, Jr. and John Nolen that appeared in Charities and the Commons journal of social work in 1906.

II. CITY SQUARES, COMMONS AND PUBLIC GARDENS

Pioneer Square in Portland, Oregon is a great example of an urban city square.

An opinion prevails very generally that a city can not have too many “squares” or “breathing places”

On account of the almost constant passing through such squares the best arrangement is to provide for reasonably direct and convenient paths along the lines most used. Where this is not done many of those who use the square are likely to be so irritated by the indirectness as to miss much of the pleasure they might otherwise receive.

Shade trees, either as a complete grove or in rows along the paths or grouped in some more complex plan, are almost essential features of such squares.

City Squares are certainly prevalent in many older cities, though they seem to be noticeably absent in Oklahoma City; especially downtown.

The properties adjacent to Bicentennial Park have not attracted the development necessary to integrate this open space into the urban fabric of Oklahoma City.

There are a few that I can think of, most notably Bicentennial Park (or Civic Center Park) which is mostly underutilized, but has found footing as the site of the Downtown in December ice-skating rink. Still, its proximity to the county jail has stymied development in the area and prevented it from being integrated into the broader fabric of downtown. Also, the Myriad Gardens would qualify as a public garden, but the flawed design and poorly related adjacent uses have to this point prevented it from being a effectively utilized by the public. This may all change with the completion of Devon Tower and more development to the south of the park as Core to Shore begins to be developed out.

The Core to Shore plan will also contribute to the urban open space with the addition of a downtown park.  This will provide a much needed “central park”, but the city still needs a truly urban open space, such as that provided to Portland by Pioneer Square, which is referred to as the “City’s Living Room”.  In the end, even if all of the plans for Core to Shore are fully realized, Oklahoma City will continue to lack quality urban open spaces – like Pioneer Square – that are effectively integrated into the fabric of the city.

Mapping Pedestrian Friendliness in OKC

July 12th, 2008

I came across this article by Jan Gehl – an urban design rock star – in which he discusses the importance of the design of the first-floor of urban buildings in attracting pedestrians and creating active streets. Downtown Oklahoma City has made tremendous gains since MAPS, but we still have very few streets with the restaurants, shopping, and (above all) people most often found in a pedestrian-friendly urban environment. In the article Close Encounters with Building (note: downloads as a .pdf), Gehl explains the importance of the first ten feet of a building and how it can either help to create a street or public space that pedestrians want to visit or conversely, create a place that pedestrians will avoid.

Gehl has done a ton of research, often using teams of researchers to observe 100m sections of street and record measurements such as the number of pedestrians, pedestrian speed, number of stops, number of times they entered/exited a building, etc. Through this he has been able to identify a handful of design attributes that can either attract or deter pedestrians by creating what he calls the ‘urban scene at eye level’. Here is what Gehl has to say about the design attributes he has identified and how they can lead to creating a good or bad ‘urban scene at eye level’.

THE URBAN SCENE AT EYE LEVEL

Scale and Rhythm

1. Scale and Rhythm

Pedestrians experience the urban scene at maximum three mph, with plenty of time to enjoy the surroundings. Small units provide a wide range of experiences, and a large number of doors provide many points of exchange between outside and inside. A scale of three mph is compact and rich in sensory experience. A scale of 35 mph also features qualities worthy of sharing, but rarely are they meaningful to pedestrians.

Transparency

Transparency

The opportunity to be on the inside looking out – and on the outside looking in – significantly broadens the range of experiences in the buildings themselves and in urban space. If we walk through the city close to the facades, the various display windows and opportunities to share what is happening in the buildings enrich our experience considerably. And people inside the buildings can follow what is happening in the surrounding urban space. Life inside and outside the buildings can thus interact for the benefit of both.

Appeals to Many Senses

Appeals to Many Senses

We can draw on all our senses when we are close to buildings, and we have sufficient time to look, listen, smell and touch the good things on offer. A wealth of sensory impressions and shopping opportunities awaits. In contrast, a string of orange posters is a poor substitute.

Texture

Texture

Good materials and fine details are an attraction for people strolling through the city. There is ample opportunity to reach out and touch the buildings and examine the smallest detail. Attractive ground-level facades offer texture, good materials and carefully crafted details.

Mix of Functions

Mix of Functions

The functions inside buildings have a major impact on the activity and attractiveness of the spaces outside. The desire for narrow units and many doors in the facade can be echoed in a desire for wide functional variation inside. The outcome is many units, many points of exchange between outside and inside, and a wealth of many different events and experiences. The department store with its ten large display windows is far less interesting than the ten different functions in the street scene opposite.

Vertical Facade Rhythm

Vertical Facade Rhythm

Walking along a ground floor fac?ade with primarily vertical rhythms makes the walk much more interesting and eye-catching. We move from ‘column to column’, which makes the walk seem shorter. Facades with primarily horizontal articulation intensify the feeling of distance – a long tiring prospect at eye height.

FACADE MAPS

With these attributes in hand, he creates a map of a city showing the “problem facades” that interrupt pedestrian paths and lower the overall quality of the pedestrian experience. For instance, this diagram compares the street facades of (a) Stockholm to those of (b) Copenhagen. The difference between the two maps speaks to a dramatic difference for pedestrians.

Maps of \

Look at the open plazas and squares in (b) Copenhagen, almost all of which are surrounded by pedestrian friendly (light facades). Whereas (a) Stockholm has block after block of poor facades with few pedestrian-friendly plazas or squares (the exception being the one shown on the lower left side. After creating these maps, Gehl has been able to work with cities in creating urban design guidelines that address the problems and has successfully attracted increased numbers of pedestrians in cities around the world.

FACADES IN OKC?

So here is the question, where do we have examples of each of these facade types in Oklahoma City? It would be great if we could create our own facade map of Downtown Oklahoma City & Bricktown and determine which areas are pro-pedestrian and anti-pedestrian according to the attribute listed above.

Here is what I think might work. Everyone could take some time to assess a street (or seven) – based on memory, by actually visiting, or using streetview- and add their assessment to our very own Google map — creating a Pedestrian Friendliness Map of Oklahoma City!

Here is an example of a green (green = pedestrian friendly) push pin I added for the Bricktown Canal as it approaches Mickey Mantle – click to enlarge.
Facade Map Example - Good Ped Environment

While this is an example of a red (red = bad for pedestrians) push pin I added for Robert S. Kerr St. just west of EK Gaylord.
Facade Map Example - Bad Ped Environment

Give it a shot. Just use the descriptions mentioned above to assess each of the attributes. Here is the form info I used that you can paste into the pushpin description window:

Good for Pedestrians? (Yes, No or Maybe)

Scale and Rhythm: Yes
Transparency: No
Appeals to many Senses: Maybe
Texture: Yes
Mix of Functions: No
Vertical Facade Rhythm: Yes

Trust your gut as to whether it deserves a Green Pin or a Red Pin. It is easy to do so give it a shot!
