Urban Habitat Chicago Site Selection Internship

Finding Suitable Space for Urban Agriculture Initiatives in Chicago

Project Purpose:Finding suitable locations for Urban Habitat Chicago, either in the form of leased office space,

shared space, or land available for urban agricultural work. Identify need for community gardens

through identifying food deserts (areas where the population has low access to produce), and

identifying suitable land for these types of initiatives as well, such as unused city-owned land or other

nonprofit or public organizations with suitable land, that could benefit through having fresh food in

their own backyard.

Internship Educational Goals:

− Familiarize self with climate for urban agriculture and similar sustainable intitiatives, as far

as gaining a picture of government programs, nonprofit advocates, urban gardening groups

and events and the affect of their programs on communities in Chicagoland.

− Practice, and enhance location decision making skills through the use of Geographic

Information Systems (GIS) software, JSON API's, online databases public and private,

various government agencies at the municipal, county, and federal level and their publicly

available, or conditionally leased data, as well as other sources such as college subscribed

data services.

− Enhancement of related computer skills through spreadsheet, database, and file conversion

software, web API mashups such as Yahoo Pipes through this process as well.

− Learn commercial real estate terminology that would be encountered in future work / issues

dealing with land, public policy, as well as methods for making locational decisions

Project Deliverables:

The project should result in the completion of a portfolio of potential sites, data derivatives related to

food access, and maps of food deserts accessible by public transit.

Project Progression / Timeline:

Setting a clear timeline of various stages of work to complete the project can be difficult

without knowing what resources would be available to begin with. Data collection consumed a large

portion of time as various statistics, tables, geographic products exist in many different locations on the

web through different entities. A few web portals were consulted for source data / information for

criteria ranging from real estate listings to obesity rates, and not all were useful in the end due to

compatibility or scale (finding or creating data at a micro-level such as census blocks can be difficult or

time consuming). A sizeable portion of time was spent in aggregating different formats so that they

could be compatible, and eventually line up for comparison and analysis. Also, a portion of time was

spent on online training for specific software modules such as one for network-based analysis, which is

explained further in the methodology section.

A general note should be made that the project scope shifted midway throughout the project as

the capabilities (and limitations) of GIS technology were better understood and a more useful

application was found. The project intended to find a more permanent location for the non-profit UHC

became the project to find vacant city land that could be more fruitful as a community garden, which

the creation and maintaining of is one of UHC's primary activities (Glenn).

Another change in the project occurred as more data became available through a revamping of

the City of Chicago data portal (“Chicago's Data Portal 2.0”). Various new data was released towards

the end of the project which aided, and somewhat derailed the timeline for the project. Consultations by

phone or in person with various people that had knowledge that could be beneficial had some effect on

methodology in the project as well.

Methodology and Analysis:The methodology, or process of getting necessary information together and performing analysis

(among other necessary steps) for this project consisted of a few key components. Network-based

Analysis and Weighted Spatial Analysis make up the majority of the methodology for the project. Some

degree of Database Manipulation and Queries was used as well, to a large extent to make data

compatible, and also to create new products. The following illustrates a general timeline of the

methodologies employed:

ProductsPhase: Data Acquisition and Design Processing for new Information Products

The majority of the steps followed a smooth progression but had to be reworked when new data was

discovered and was able to be incorporated into the project.

Spatial AnalysisA common application of GIS technology is Spatial Analysis. Spatial Analysis is the

aggregation of multiple criteria that have a spatial (locational component) into a compatible and

comparable format and then the manipulation of this into useful information products. This application

is often what differentiates simple map products and viewers as trends and phenomena can be put into a

visual and defined format that aids the decision making process. Spatial Analysis products save time

and work by narrowing down possibilities into most suitable ones ("ArcGIS Spatial Analyst |

Brochures/Whitepapers").

Spatial Analysis often involves the conversion of vector defined locations (points, lines,

polygons representing points of interest such as grocery stores, means of moving around, and defined

boundaries such as census blocks or tracts, respectively) into a grid surface (raster, or collection of

square cells) with values representing the criteria or phenomenon. The conversion of input data

representing criteria such as population density, distribution of grocery stores, distances from public

transit into a common surface format is how a comparison between all of the input information can be

made, and a resulting product produced. Spatial Analysis served as a big portion of the methodology of

this project.

Data Mining, Data Design Performing the analysis required for the needs of this project consisted not only of determining

what factors to consider, but how to get information representing these factors (data). The process of

getting necessary information (data mining) creating a suitable data design, which is a design and

process for aggregating together multiple datasets into a compatible and comparable format

(Tomlinson, 93-107). In a geographic information system, data design must take into consideration

spatial characteristics of the datasets. For example, data from a USDA study of food deserts was

available only at the county level, which served no purpose for analyzing areas within Chicago. Often

times it is sought to somehow capture various characteristics / parameters at the most mico-level, or

lowest common denominator available.

A grid surface with each cell representing a 10' X 10' area was an original design, but when

seen through to analysis, the results seemed to not accurately portray spatial patterns that were being

looked for (see Figure 2). Some of the combined surfaces in this method received more “points” than

others per cell and didn't seem to prove anything. This was because the factors, such as population

density were being compared too directly with relatively related ones such as access to rapid transit.

A different method was applied afterward: the surfaces derived for community garden locations,

grocery store locations, and population distribution were all interpolated into census blocks. Each

factor was now comparable at a block level. Although the block-level design lost locational accuracy,

trends were more visible, and a more meaningful product resulted from this change in data design after

the initial analysis.

Result: Poor representation – almost all areas

accentuated, better results

Network-based AnalysisDensity, or distribution based analysis was suitable for factors such as population density,

density of grocery stores, and density of community gardens. These surfaces display relative

concentrations of these factors well, but when analyzing access to public transportation, which was

seen as a key parameter in selecting a site that is not only suitable but in-line with sustainability – a

goal of Urban Habitat Chicago. The primary reason for this is that the movement of people is restricted

by streets and this has to be taken into consideration. Rings depicting buffers of 50, 100, 150 feet are

not suitable – a bus stop might be 50 feet away from a person at a given location if they had the ability

to fly over them, or dig underneath, but in reality it might be 74 feet or so by walking on the streets.

This is why Network-based Analysis must be used. Network-based analysis starts by building a

network of traversible nodes and lines connecting these nodes ("Essential Network Analyst

Vocabulary"). The lines represent walkable roads in our case, and the nodes turns between roads. For

more advanced applications such as driving, speed limits and one way streets must be programmed in,

and slopes calculated for mountainous areas (not in Chicago, though). For our purposes, a network that

can be traveled at 3mph (approximate rate of person walking) was created. The analysis then calculates

distances from inputs such as bus or train stops, and outputs a result.

Fig.3: Ring Buffers vs. Network-based Analysis

A: Various distance ring buffers around stops B: Walkable street network-based analysis

Result: “As the crow flies” analysis leading to

inaccurate results

Result: More accurate, based on travel times

The network-based analysis method was employed to more accurately look for areas of Chicago

with good access to public transportation. Luckily, data is published by the CTA (Chicago Transit

Authority) in a universal format called the GTFS feed. The GTFS, or General/Google Transit Feed

Specification is a standard for publishing data for public transit agencies so that it can then be plugged

directly into a myriad of applications such as route-planning services, schedules, and mobile

applications (“General Transit Feed Specification”). The data from the CTA Developer portal

conformed dilligently to this standard, for the most part (“GTFS Data Feed | CTA Developer Center").

Several issues arose with the network based analysis when analyzing access to public transit.

The very first results placed most of Chicago as accessible to public transit, the reason for this being

that all bus stop, and CTA trains were used. The bus information had to be taken out of the picture or

ranked. Most of Chicago is well covered with bus stops, but not all of these are served as frequently,

and factoring this into the equation was necessary, and a way to rank the stops. Stops needed to be

ranked and emphasized or de-emphasized more based on these criteria.

Data Manipulation and QueriesSeveral of the datasets used throughout this project were re-worked to fit together better, but

Page 9: Urban Habitat Chicago - Community Gardening Analysis

Finding Suitable Space for Urban Agriculture Initiatives – Mike Bularz – Summer 2011 9

one of the more intense-reworkings was with the CTA GTFS feed, since a lot of the data had various

relationships. The CTA GTFS feed consists of tables representing:

− Stops: areas where a vehicle stops

− Routes: specific paths traveled by vehicles

− Trips: Trips are a sub-category of routes. There are many trips by more than one vehicle on

a given route, on a give day

− Stop Times: Times a vehicle arrives at a stop, and times it departs (in case there is a long

period between these two)

− Calendar: Two tables, one showing days a route is served, another showing holiday changes

− Frequency: This is supposed to show how often a route is served, and was incomplete

(“CTA GTFS Data Feed”). Frequency was calculated by myself to weigh various stops.

The tables have 1 to 1 and 1 to many relationships, and a preliminary arrangement of these was as

follows:

Fig4: Table relationships (1:M = One to many, 1:1 = One to One, M:1 = Many to One)

After arranging these relationships between the tables, new data was created through the use of

selections and summaries. One example of information derived was the number of stops per hour for

each route, this was done by summarizing stop times by trip number and routes by number of trips, this

gave a count of how many stops per trip per route. This was divided by 24 hours as the CTA data gave

times for a given day. A selection was made of stops that only have night-owl service, as this was one

Page 10: Urban Habitat Chicago - Community Gardening Analysis

Finding Suitable Space for Urban Agriculture Initiatives – Mike Bularz – Summer 2011 10

way to classify more active bus routes. Punishing the stops by how much time was lost versus walking

at 3 mph through simple math was also tried.

Plugging the derivatives into the Network-based Analysis

After attempting to identify very transit-friendly areas, it seemed that where one bus stop was

lacking, another made up for it, and similar results not identifying any specific clusters in the city were

derived. It was decided to simply use train stops and add in metra stations to obtain some transit-

friendly areas. Figure 3B above is a closeup of one of the more clear results that was used in the end.

Aggregating all results into final weighted Spatial AnalysisFinally, derivatives portraying distribution of the population, distribution of grocery stores,

distribution of community gardens, and access to rapid transit could be aggregated in an overlay. An

overlay basically performs raster mathematics: each cell in a surface / raster is added up, averaged, or

subtracted. For instance, one may take an elevation surface, and add on to the sea level to show areas

affected by a 3 foot storm surge, these areas might be multiplied by a binary raster (1 for yes, 0 for no)

of where there are people, this would result in information on where to send rescue crews.

In this case we are saving people from under-nutrition. The basic method in overlaying the 4

derivatives is to convert each of them into a surface. The next step is to rank each cell in values 0 – 9 to

get a set of comparable surfaces. A surface of cells representing distances from grocery stores is

incompatible for subtracting from a population surface which contains cells representing how many

people are estimated for the area. For example: a cell corresponding to x latitude and y longitude has

355 people, is 250 feet from the nearest grocery store, and 18 feet from the Red Line. These values are

incompatible; each cell must be re-classified on a scale of 0-9 in comparison to all of the other cells of

a given surface. Population score 4 + Grocery score 2 + Transit score 9 = 15 / 27 possible points for

that cell, the cell scores 0.55 / 9.

For the purpose of this project, a weighted-overlay is done. This module allows for adding an

emphasis on the various factors / combined surfaces. To obtain the final result, 40% importance was

given for access to rapid transit, 20% for access to grocery stores, 20% for being far from existing

community gardens, and 20% for being in a high population density. Grocery store, community garden

distribution, and population surfaces were created at the census block level, the access to transit surface

was not, to preserve true distances.

ResultsThe resulting data emphasized some pockets in the city where urban gardening would be

feasible, and was extrapolated onto points representing city land parcels. The highest scoring parcels

scored 7 / 9, and there were only a few of these, there was a significant amount of parcels with a score

of 6, and a majority score 5. A few others received the low score below 5, none scored less than 3. (See

Figure 6B). Figure 6A shows all land in the city, and how it scored on a block-by-block basis.

Trends Observed

It was not uncommon to see pockets of accessible food deserts on the south side of the city.

Since access to transit was part of the equation, the results may bias towards areas closer to the CBD

(Central Business District – the Loop) as there is generally more accessibility to transit. The scope of

this project focused on not just identifying food deserts, but ones that are accessible by train, and this is

why the bias exists. Another trend was that the South side had higher scores because the West side had

a significant amount of existing community gardens, which were also a factor in this analysis.

An interesting but not pictured trend is the high density of available city-land on the West and

South sides. This may be due to higher foreclosure rates, as these areas have the poorer population of

Chicago. This may be a cause as to why the two graphs in Figure 6 are very similar.

Quality of Results, Methodology Re-examined

The methodology used to make informed locational decisions could benefit from potentally

different approaches. Firstly, other reports have found food deserts in a much more meaningful

methods. Mari Galagher's pivotal report on food deserts also analyzed areas based on obesity rates,

death from heart-related problems, among other factors – the correlations between this public health

data and the food deserts are very high, and prove a poignant, grim point. This project focused on

Page 13: Urban Habitat Chicago - Community Gardening Analysis

Finding Suitable Space for Urban Agriculture Initiatives – Mike Bularz – Summer 2011 13

factors such as public transit access, among other considerations explained further in this report, and

the results do not fully address food deserts, rather, good places to start a community garden.

Further, the data used, and not used for this analysis could have been leveraged to produce an

even better result had the constraints of time not been as inhibiting. A midpoint switch of the scope of

the project from looking for office space, to looking for public land put analysis in about a 1 to 1.5

month window.

Crime data, which could have been useful to factor in safety concerns for volunteers was not

leveraged, even though it was obtained, and processed. The crime data was released for the first time

through the city's new FOIA (Freedom of Information Act) portal towards the last weeks of the project,

and the dataset is so immense that it was too difficult to pinpoint any “high crime” areas because of

how much crime actually happens in Chicago (“Crimes”). Details of this are too much to digress in this

report.

Grocery store data, which was processed in a manner that simply acquired any food-based retail

is populated with records for businesses that aren't true sources of nutrition, such as convenience and

liquor stores, corner stores, among other things. A retooling of the method of acquiring this data could

categorize the records (stores) into more useful classes: supermarkets, malls, convenience, etc.

If time had permitted, a network of the city's transportation options could be modeled, and then

used to process the resulting high-scoring parcels for true accessibility. Reversing the model to see how

much of the city could be accessed from each parcel, or better, how much of the population, would

result in an even better analysis. The creation of such a dataset and processing all of this information

could consume from 4-6 weeks, based on my experience from running this project.

Selected City Parcels

A note on selected parcels for the portfolioThe presented available land is just a glimpse of potential land. A bias was present in selecting

parcels closer to the North side of the city, where a majority of Urban Habitat Chicago volunteers not only live, but are more active in community garden efforts, not only in actual community gardens but ties to organizations active in events and projects in the same area. Ways forward...

There are similar organizations tied to their own areas of the city as well, and using GIS technology to increase awareness of available land opportunities through not only showing food deserts, but making the information publicly available through the construction of a public-map viewer would be a step in the right direction. My site-selections were biased to UHC's needs and logistical capabilities, there might be other organizations that are more active in other endeavors – such as rehabilitating old buildings, deconstruction, etc. that could find these sites more suitable, and find some of these sites literally “right up their alley”. The details of this are outside of the scope of this report.
