The goal of this project was to research urban food systems and design based on the theory
Food Urbanism; how food relates to the organization of a city and how it becomes infrastructure
that transforms the urban experience. Productive landscapes as tools to sustainable growth have
only recently been written about in the U.S. and Canada. Continuous productive landscapes have
the potential to become a tool and or mechanism to sustainable growth in urban communities.
As infrastructure in a city or town, continuous urban agriculture (UA) has the potential of being
a thread that is woven through a community creating a rigid and ecological backbone forgrowth connecting neighborhoods, open spaces, and urban markets. Research is based on
case studies, interviews of producers and city officials in Ames, IA and observations of UA in
London, UK. This research demonstrates that urban food systems have a potential of creating
environmentally, socially and economically productive communities.
Key Words: landscape architecture, planning, urban food systems, urban land inventory,

introduction
Food has been the center of civilization and cultures since the formation of the first nomadic
societies. In the next 20 years the global population is going to be 60% urban (Girardet 2004,
3) and food access is going to become a primary issue. In 2007, the globe became an urban
society by passing the rural/urban threshold, while the U.S. has been primarily urban since
1910 (Kulikowski 2007).
As designers and planners of urban landscapes, landscape architects hold a vital tool in thegrowth of any Iowa community. Food is both a local and global issue. The lack of productive
urban land, food insecurity, uncontrolled urban growth, the lack of stable local food markets,
land use conflicts in the peri-urban areas, and a general lack of societal knowledge of food
growing and preparation fuel these discussions.
Cleveland, Ohio and Vancouver, B.C. are prime examples of how legislation can impact the
growth of urban food systems while improving other sectors of the community. Cleveland has
implemented an urban garden zoning district and the program Gardens to Greenbacks. TheVancouver Food Policy Council has created their Vancouver Food Charter to identify goals and
has also assisted in creating guidelines for urban agriculture in private development. Urban
communities in Iowa have a agricultural heritage and urban food systems have an enormous
potential. This report is meant to be a urban case study of the city of Ames food system and a
manual about food urbanism; including proposals for the city of Ames.

P I: the urban food systemAn urban food system has the agenda to guide the development of a sustainable and integrated
system of food production, processing, distribution, marketing, consumption and waste
management in an urban landscape. An urban food system integrates live, work, and play into
the activities of a productive landscape. Through infrastructure developments of roads, railroad
lines, municipal utilities, walking and biking trails, and bike commuter lanes an integrated
urban system can be created. Food infrastructure is the underlying foundation of a sustainable
community. By utilizing the development of urban food production infrastructure as criteria forurban growth, a community can have urban growth while still on a sustainable path.
The success of an urban food system relies on differing pieces of infrastructure to utilize
each others resources. An urban transportation system should be in conjunction with the
distribution of both products and residents in an urban landscape. Institutional and community
food processing must be common amongst different schools, churches, NGOs, agencies, and
governments. Food production must be integrated into the daily activities of all community
residents through recreation and communal gatherings. Positive personal development can be
achieved by integrating food production into community recreation parks. Marketing must be
the common thread amongst all urban food producers and consumers. Through cooperative
market outlets a larger series of food access points can be developed supplying healthy fresh
and affordable food. And finally a sustainable community is based on an ongoing never ending
system with little input. Waste management is the sector of an urban food system that must be
integrated with a waste recycling and reuse program in a community to recycle the nutrients in
the food production system.
A healthy urban food system means a healthy and sustainably growing community that iseconomically, environmentally and most importantly a socially productive community.

why urban food systems?Last October in the New York Times Michael Pollen addressed the future new president as
the Farmer in Chief (Pollen 2008). In his letter Pollen explained to the next president that food
policy will become a leading issue above others during the next four years. He explained to
him that by reinventing the entire food system it would
reduce the impact of many other issues. He was trying to
explain how every issue today is linked some how to the
food system. These are the same issues that are being
shared by organizations and individuals in the farming,
health, human welfare and many other sectors. Access
to healthy food is a critical issue. Chicago is only one
city of many combating food deserts. Food deserts are
populations either urban or rural that do not have access to
grocery or food market stores. Convenience stores instead
fill this void. These stores though only provide beer, soda,
potato chips and other highly processed foods. Figure 1
represents food deserts present in South Chicago (Group2006, 8).
Environmentally Productive
As diabetes and other chronic diseases increase, health
care costs will continue to rise. Last fall the Henry
J. Kaiser Family Foundation released that employer
sponsored health plan premiums are rising drastically and
workers are paying on average $3,354 annually toward family coverage out of their own pay
checks (Singh 2008).
Environmental health is an enormous concern of many organizations and individuals in the
local food system movement. On average food travels 1500-2500 miles from field to plate
and in return is producing extreme levels of carbon dioxide at the same time. Rich Pirog in
the Leopold Center has written about Iowas food system and, more specifically, the food
systems impact based on food miles. Pirog compared the impacts of a conventional system,
figure 2
8/9/2019 Food Urbanism - A Sustainable Design Option for Urban Communities
11/92a sustainable design option for growing urban communities page 11
Iowa-based regional system and a local system (Pirog 2001). He analyzed each system based
on fuel consumption, value of the fuel consumed, C02 emissions and distance traveled. Table
1 shows Pirogs findings for each food system and its impact on the climate based on food
miles. His findings support that an urban food system would be environmentally productive as
it would shorten the span between field and plate and reduce greenhouse gas emissions (Pirog
2001, 33). The conventual agricultural sector in 2005 produced 8.2% of the CO2 emissions
based out of all the U.S. economic sectors. Transportation (27.5%), industry (18.6%) andelectric power (33.5%) were the sectors ahead of the agricultural sector (Hofstrand 2008).
The current agricultural sector is the primary cause of these other industries impact. For
example the transportation sector releases many CO2 emissions because it must ship the
agricultural products across the country.
In addition to food miles, food deserts, and
health care; urban land use is a common issue
in urban communities. Manicured lawns, in
the U.S., are out of control. Today manicured
lawns are the largest crop in the U.S. There are
three times more acres of lawn than irrigated
corn covering an area of about 330,000 square
miles (Lindsey 2005).
Economically Productive
In 1929 Americans spent $4 out $5 at independent retailers but by the mid-50s many
consumers patterns were being drastically affected (Mitchell 2006). Af ter WWII when a larger
portion of the population was able to move and live in suburbs of American cities it opened up
new land for chain stores to grow. Today chains have become the dominate market in all areas
of the economy. In 2005 the top ten retail chains had a hold of 30% of consumer spending.
Twenty percent of this spending was in food sales and 46% was dominated by 5 companies:
Walmart, Kroger, Albertsons Safeway, and Ahold. Independent groceries only had 17% of
the sales. Even the clothing sales were being dominated by a few. Target along with specialty
stores like GAP Inc. are leading the market. Forty percent of the prescription sales are by
Walgreens, CVS and Rite Aid (Mitchell 2006, 11). This can be seen in many other areas such
as books, restaurants/entertainment, and even on the World Wide Web. This narrowing of the
market is even apparent in agriculture.
In the U.S. we have 4 million fewer farmers today than we did in the 1930s. Farms have
gotten larger and are owned by a smaller group of people everyday (GRACE 2008). In 1910,
table 1
8/9/2019 Food Urbanism - A Sustainable Design Option for Urban Communities
12/92food urbanismpage 12
42 cents of every dollar spent on food went to farmers and 59 cents went to marketers
and input providers. By 1998 farmers only received 9 cents, input providers 24 cents, and
marketers 67 cents (Shuman 1998, 58).
In the mid 1940s Walter Goldschmidt along with two other sociologist C. Wright Mills and
Melville J. Ulmer each studied the effects of a local vs. nonlocal business base in similar
communities (Mitchell 2006). Their studies compared two communities that were similarin population, climate, and distance from major urban centers. Goldschmidt compared the
two communities of Arvin and Dinuba both located in the Sun Joaquin Valley in California.
Goldschmidts findings allowed him to conclude that Dinuba had a higher standard of
living because it had a base of local businesses instead of non local. His analysis of two
communities showed that Arvin had a handful of large agri-businesses and Dinuba was only
small family owned farms. Arvins farms were 9 times as large and had a larger median
income. Dinuba though had much more impressive stats (Mitchell 2006 73-4). There was
less income inequality and there were many farmers, small business owners, and independent
processors. In addition compared to the one elementary school and tiny private playground in
Arvin, Dinubas community infrastructure was enormous. It had better streets, sidewalks, and
garbage services that were better in both quality and quantity. It had 4 elementary schools, 1
high school, 3 public parks, and twice the civic and social organizations. Its two newspapers
were each larger than Arvins one paper (Mitchell 2006 73-4).
Urban areas would be the best place to implement production without competing with the
production of commodity crops outside of urban areas. Today in Iowa Dave Swenson from
the Economics Department and the Leopold Center at Iowa State have combined forces todevelop evidence of the positive economic impacts of increased fruit and vegetable production
and consumption in Iowa. Swenson created a multiple of scenarios each varying in the
amount of produce grown in Iowa, amount of consumption in Iowa, and the amount marketed
directly vs. indirectly (Swenson 2006). In his second scenario he models 25% of the 37 fruits
and vegetables consumed in Iowa as produced by Iowa farmers. The produce is then 50%
direct marketed by farmers to consumers and the other half is indirect marketed through
the wholesale distributors and conventional grocery stores. He concluded that there would
be a total industrial output of $104.5 million, a labor income of $38 million made by 1,345
jobs. Swenson then concluded that this increased production had a net impact of $92 million
of industrial output and $33.5 million in labor income made by 1,183 new jobs (Swenson
2006,17). By designing our communities around food production and only increasing fruit and
vegetable production in Iowa by 25%, our Iowa economy would be benefited greatly.

Sociologically Productive
In Dinuba and Arvin Goldschmidt concluded that since the residents had a higher standard of
living they were more willing to engage in public affairs because they had built up community
equity to the point where they felt they owned a piece of the community and should have
a right to make decisions for its future. Thus the local economics of Dinuba created a
sociologically productive community.
Sociological productivity is more difficult to measure. Jan and Cornelia Flora of the North
Central Regional Center for Rural Development have developed their Community Capitals
Framework (Development 2008). This framework defines the seven types of capital in a
community. Their framework explains that one local dollar protects natural capital and adds to
cultural, human, social, political, financial, and built capital (Development 2008). By increasing
social capital the Floras explain that a community will have a strong foundation and become
a sustainable community. They argue that social capital creates the binds throughout the
community and into the surrounding region. Jane Jacobs in her book, Death and Life of Great
American Cities, calls local businessman public characters (Jacobs 1993). They are what bind
communities together. When they talk to many people throughout the day they become like a
news cast that spreads information between individuals (Mitchell 2006,78). Even though the
relationships that are created between local businessman and other residents are informal
they become personal and multifaceted and gain an interest in each others well being. As
these relationships grow social capital is created. People learn many new faces and create
informal relationships that reduce social diversions and foster empathy and friendship (Mitchel
2006, 80). When local residents speak with each other and create relationships between largegroups of people social webs are created. These webs become avenues where job openings
are advertised and filled, innovative ideas created, skills traded, and business trades made
(Mitchell 2006, 80).

The first step in developing an urban food system is to conduct a urban food system audit. The
city of Ames was chosen as the urban case study based on a criteria developed for selection.
The case study is meant to evaluate the current status and flow diagram of the urban food
system. Case study selection criteria included population (60,000 - 10,000), diverse ethnicity,
access to base data, presence of linear ecological landscapes, land area, population density,
home ownership, stable urban centers, stable local markets, population of local farmers,
forward-thinking officials, population growth, and per capita median income. Ames was
chosen both on the criteria and personal knowledge of the community.
In addition to case studies and background knowledge (included in Continuous Productive
Urban Landscapes: a sustainable design option to growing urban communities in Iowa,
phase one report) interviews were conducted
with city officials on the local controls,
policy, and structure of Ames. To understand
the fundamentals of the current local food
system, local producers were asked basicinterview questions about the fundamental
aspects of their food production. Figure 3
on the left represents the research process
followed to obtain an understanding of
Ames and the theory of Food Urbanism.
Appendixes A and B include interview
questions conducted with officials and
producers.
Additional research and analysis was then
conducted on the number and location
of the citys urban markets and nodes,
grocery, speciality food stores, and farmers
markets, restaurants and convenience

policy + local controls + structure
It is important to understand the local controls, policy and structure of both Ames and
unincorporated Story County. By interviewing local planners and officials data was gathered
about Ames controls on temporary markets, urban growth strategies, the urban fringe plans,the local approach at managing vacant land, strategies used to manage park land, and controls
on current community gardens within in Ames. In addition to current data and information a
dialogue was created, with the local planners and officials, on designing communities around a
framework of urban agriculture.
Managing Urban Growth/Urban Fringe Planning
Ames and Story County planners have a long term agreement to work together on all urban
growth planning strategies. After working together for a long period of time the two cities
along with the city of Gilbert have completed an Urban Fringe Plan. On the following page is
the current Urban Fringe Plan for the city of Ames. After speaking with the planning directors,
it was determined that planning is based on current utilities and services. Urban growth
areas are first determined based on whether current utilities and services are able to support
any new development. Utilities and services are defined as sewer, water, electricity, gas,
emergency service, and etc. Other criteria that are considered are environmental constraints
and current traffic patterns.
City and county planners each agreed that the appropriate places to consider while studying
food urbanism would be the Urban Service Areas, within the urban fringe plan. They agreed
that urban food system infrastructure would be able to guide future growth into these areas.
These areas are projected to be areas of future urban development based on urban growth
plans. Within the city of Ames these areas are primarily located on the west and southwest
edges of Ames along Hwy 30, Nor th and South Dakota Avenues, and West Lincoln Way.
Figure 4 represents the city of Ames urban fringe plan. County planners also recommend
conservation easement lands and any land that is classified as agriculture or farm service
areas. The planners recommended conservation easement lands because low impact peri-
urban agriculture could be utilized as a management tool for these lands while conserving the
parcels.

Managing Vacant Land
City planners in inteviews indicated that vacant land is seen as a valuable resource. Vacant
land in the city of Ames was defined as parcels that are of nuisance to adjacent land uses or
are hard to develop. The city assessor uses a existing use code in their parcel data to define
vacant as empty parcels or empty structures. Planning staff expressed that studying existing
aerials and current parcel data was the best way to locate vacant or underutilized parcels.
Temporary Markets
Since a urban food system would be economically productive and grow and harvest products,
it is important that markets be created within the system. It is important though that these
markets are regulated to prevent negative effects on the health and well being of the public
population. Examples include the sale of contaminated food or illegal the sighting of a vending
trailer in the public right of way. The central Iowa climate does not allow crops to be grown
and harvested year around outdoors thus some markets within the system would only be
temporary for 8-10 months of the year. In addition to understanding planning goals and
strategies for the city of Ames it was also important to know any current regulations or laws
that would regulate any form of a temporary market. Within the City of Ames Municipal Code
there are many requirements for markets and vendors. Section 22.4 of the municipal code has
restrictions on temporary obstructions. These requirements are meant to control the issuing
of permits for obstructions and limit them so they dont cause any harm to the public. Section
17.26 thus places requirements on specific outdoor markets. The code reads:
that any person who, for the purpose of selling goods or services, occupies a place out of
doors, other than on public property, or who for said purpose occupies an indoor place on
an intermittent or temporary basis only, and who does not have any indoor place in the city
where the same selling of goods and services is done by said person on a continuous and
permanent basis, shall obtain and wear, in a manner plainly visible, a valid registration and
identification badge issued by the City Clerk.
It is required that all markets apply for a permit from the City Clerk so that all markets can be
inventoried and regulated to avoid any potential harm to the public population. In addition to
markets vending has many requirements. Their requirements in Section 22.11 22.23 read:
It shall be unlawful to sell, or offer for sale, any food, beverage or merchandise on any street,
sidewalk, alley, city parking lot or other thoroughfare without first obtaining the applicable
license or permit, such as a Vendors License, a Newspaper Dispenser Permit, or a Sidewalk
Cafe Permit.
8/9/2019 Food Urbanism - A Sustainable Design Option for Urban Communities
19/92a sustainable design option for growing urban communities page 19
The following requirements and standards are placed on all vendors:
1. The vending stand shall be of such a size and so placed that it does not
obstruct the orderly flow of pedestrian and/or vehicular movement(s).
2. The vending stand shall be placed so as not to obstruct visibility at street
intersections or to obstruct driveway entrances.3. All vending stands shall provide a litter receptacle which is available for the
vendors patrons use.
4. All vending stands shall be attended at all times and removed during hours of
non-operation.
5. Upon removal of the stand, all litter and trash shall be picked up.
6. Vending items shall be only those stated in the application.
7. The vending stand shall be placed so as not to obstruct the view of
merchandising displays of other businesses abutting the sidewalk.
8. All vending from motor vehicles shall be conducted in such a way as not
to restrict or interfere with the ingress or egress of the abutting
property, create a public nuisance, increase traffic
congestion or delay, constitute a hazard to traffic,
life, or property, or be an obstruction to adequate access to fire, police,
or sanitation vehicles.
Strategies in Managing Park Land
It is also important to understood the strategies of the parks and recreation department. A
urban food system will utilize current open space and it will act as the missing piece that
creates a network of open spaces. Within the parks department all future planning is done
through the park master plan and the citys Capital Improvement Plan. Mowing and controlling
weeds and invasive plants is the primary management strategy for each park.
Currently within the city there is one example of community gardens. Thir ty-six plots are
located south of the Department of Transportation service yards along Squaw Creek on park
land. The plots are 10x40 and are on an annual rent cycle of $15/year. They are managed
by the Iowa Natural Heritage Foundation. Even though there is interest in more community
gardens there is a concern by the city of the hours needed to manage a system.

fundamentals of current local food system
In order to design a urban food system in the case study community it was impor tant to
understand the fundamental systems and infrastructure that make the local food system
operate. Through interviewing eight local producers a better understanding was gathered
of current producers, markets, and products in the local supply chain. During a three week
interview process producers were interviewed on their mechanics, storage, markets,
processing, products, labor, size, their struggles, and their input on programs to bring farmers
into urban areas.
Interviews were with:
Picket Fence Creamery
Onion Creek Farm

Story County, Iowa: Local Food System
As part of an increasing rise in local food awareness, the Story County Planning and Zoning
department completed a study on the county food system (Department 2008). They found
that the county was very diverse with 18 growers and 50 producers counting the surrounding
counties. These producers are marketing their products in the region. In 2006 there were 17
CSAs in the region, 2 farmers markets in Ames, grocery stores that were selling local products
(Wheatsfield Coop, HyVee, and Fareway), and a handful of restaurants using local goods in
their menus (Department 2008, 13-14).
In a survey that was administered by the depar tment producers replied saying they were
looking to expand production or to build greenhouses. Many though replied explaining the
hardest issues of local production. Many explained that there was enough labor but the access
to land was limited. This restricted the number of new farmers. The largest concern in Story
County as with other counties is the lack of regional food processing or meat lockers to add
8/9/2019 Food Urbanism - A Sustainable Design Option for Urban Communities
21/92a sustainable design option for growing urban communities page 21
value to their goods before market. Livestock producers were the most concerned because
there are few federally or state inspected processors in the region. This limits their ability to
market their meat for resale and to have it certified organic. This is a concern because by law
in order to sell beef, pork, chicken or any other meat in a resale market the carcass has to be
inspected by a certified individual before it can be divided into its respectful parts and stamped
for resale.
The senior thesis interviews focused on the fundamentals of the local producers operations.
In order to design and plan a local urban food system it was important to understand where
current producers are farming, what mechanics they are using and the markets they are selling
their products at. Each interview was conducted at each of the producers farms.
Peri-urban/Rural Production
Of the eight producers interviewed, four were located slightly outside of city limits. The four
producers located near any city limits were in prime locations. Their locations allowed themto create direct markets so that their customers could purchase their products directly on the
farm. This allowed the farmers to create a transparent system so that customers understood
how their products were being produced. The other four producers were located in rural
areas that were primarily row crop agriculture. One of these four produced grass fed beef just
outside of Ledges State Park. Since the producer was using rotational grazing his farm acted
as a buffer between the State Park and the row crop agriculture that surrounding the farm.
The smallest producers ranged about 2 5 acres while the largest producer had 100 acres forvegetables and 700 for row crops. This represents the scale of local producers in the region
very well. Even between the two producers that market grass-fed beef each is at opposite ends
of the spectrum. One producer has 160 acres of pasture and is looking to expand this part of
his business; in addition to his dairy production. The other producer outside of Ledges State
Park has 40 acres and 15 head of cattle. Both producers agreed that two acres per head is a
suitable planning calculation per year. All producers expressed the importance of some land
being laid fallow every year as part of a crop rotation system. They expressed this because
it allowed the soil to rest between production years. To return fertility to the soil all of the
producers either add organic matter or compost and some will plant green manure crops afterthey harvest. These crops then are tilled into the soil and added to the organic matter content
in the soil. Since the price of land is high currently many producers mentioned how hard it is
to expand. One producer has recently just started to rent 20 acres and grows produce, as a
voluntary agreement between the landowner and themselves, on another acre parcel.
Mechanics/Infrastructure of the Regional Food System
8/9/2019 Food Urbanism - A Sustainable Design Option for Urban Communities
22/92food urbanismpage 22
A urban food system will be commercially productive and will incorporate parks and
community gardens into its network. To be able to design commercially productive areas, it
is important to understand what infrastructure is required. All producers explained that most
of the labor is done by hand instead of by equipment. The crops that are primarily grown
cannot be harvested by equipment efficiently for the small quantity produced. Many if not all
farmers though did use roto-tillers to prepare their land for planting and to control weeds. Thendepending on the scale of production and crops produced some producers owned small utility
tractors, mowers, skid loaders, planters, and other tillage equipment. In addition to the larger
equipment every producer had some form of a wheel barrel or garden cart and all the shovels
and rakes one could want. Many producers expressed the constant battle with weeds and
ways they control them. Many explained by using straw or plastic barriers many weeds can be
prevented. For those weeds that did grow though stir-up hoes, propane torches, and/or natural
products were sprayed to control weeds and pests.
Storage, Processing, and Delivery
Since many producers sold to farmers markets or had their own direct markets they needed
a place to store and process their products. Every producer had some form of a storage
building. Some were simply lean-tos that protected one from the elements and others had
garages and sheds. Within these small structures producers would use coolers to store
produce that needed to be cool and others would use old refrigerators or shelves as storage.
After products had been harvested producers washed all products to remove soil from root
crops or remove any pests or soil from greens. After washing the products they would bepackaged in cardboard boxes or plastic crates by weight. Whether the producer was putting
together shares for their CSA members or getting ready to make a shipment to
Hy-Vee, this system allowed him/her to quickly and easily sell his product at a certain unit
per pound. Each producer had a different system of getting products to their customers. For
those producers selling to re-sale markets the grocery store produce manager would contact
them when they were ready for a new shipment. Producers otherwise would either prepare for
farmers markets the day before hand or early the morning of. CSA producers would deliver
their shares to their members or have their members pick up their own shares at the farm.
Producers would use small trucks and sometimes enclosed trailers. One farmer just outside of
Ames used an electric truck to make his deliveries to the restaurants he sold to.
For those producers that had livestock or dairy they would either do their own processing
or take their livestock or milk to a processing plant. Many producers expressed the issue of
the lack of a regional meat processing facility. One producer that sells free range chickens
expressed that because he has to haul his livestock to an inspected facility in far southwest
Iowa it about offsets him producing his chickens in a free range system.

23/92a sustainable design option for growing urban communities page 23
Local Markets
All producers had found their own niche in the local markets. Many producers marketed their
products to Hy-Vee, Fareway, Wheatsfield, and ISU Dinings program, Farm to ISU. Producers
rarely marketed their products in a single fashion. Between the CSAs the number of shares
varied between 15-64 families. Others sell at farmers markets in Ames, Johnston, DesMoines, and other communities. As was mentioned earlier some producers direct market their
goods from the farm. This allows them to market their products everyday of the week. Direct
marketing goods also creates other avenues for producers to work together and sell each
others products. And finally, some producers also sell to restaurants like the Caf in Ames or
the Raccoon River Brewery in Des Moines.
The Potential of Programs to Create Inventories of Land within City Limitsfor Production; To Assist In the Management of Vacant or Underutilized
Land
As a part of each interview each producer was asked about their thoughts and ideas about
a program that would create an inventory of urban parcels that are vacant or underutilized
that could be used for production. Each producer thought this was a great idea as it would
decrease the distance that products would have to be delivered, it utilized land to its potential,
and helped managed land within the city. The producers expressed that to make it efficient to
be farmed commercially the site would have to be half an acre or greater. The smaller sites
could be used for community gardens instead. In addition to the question many producers also
recommended that old schools or other vacant buildings could be used as processing centers,
job training centers, other education programs or housing.

urban markets +nodesUrban markets and nodes create the foundation to the marketing of products within an urban
food system. This evaluation within the urban case study evaluated the location of each urban
market and node within the city of Ames. These nodes and market centers are important to the
food system because they are the centers were products within the urban food system can be
marketed to the greater city population. Outdoor markets, grocery stores, speciality stores, and
other commercial activities can be located at these nodes because they are intersections of
circulation. Diverse nodes and markets create an active streetscape at every hour.
This evaluation informed the site chosen as a existing urban fabric to be used as a case study
to implement the proposed urban food system typology and circulation.

grocery + specialty food store + farmersmarketWith the rise of food deserts and food insecurity becoming an issue it was important to
evaluate the location of current points of access to healthy food. In 2006, in Story county
there were 13 grocery stores, 36 convenience stores, 6 specialty food stores and 2 farmers
markets. There were 6,446 people per the 13 grocery stores and 13,967 per the 6 specialty
food stores (Eathington 2008). It is important to understand the number and location of these
markets today in addition to the outdoor farmers markets. Since Ames is the home of Iowa
State University and since Ames has a very diverse population it is important that food itemsare available for each culture. For example the Indian culture is very large within the community
thus it is important that Pammel Grocery is a source of food items specific to their food
culture.

restaurant + convenience + food pantrySince 2000 households receiving food assistance has more than doubled (720-2,048)
in Story county. The average benefits per person have nearly doubled as well ($75.16 -
$148.96) (Iowa State Data Center). Food assistance (recently changed from food stamps)
supports families and individuals near or below poverty. Without an ample supply of fresh
food items it is important that households have supplementary access points to sources that
accept food stamps. Restaurants including fast food, convenience stores and food pantries
become the second tier following grocery stores and markets. It is important though that
fast food restaurants and convenience stores do not become the first tier of food access asin food deserts. In 2007, in Story county it was estimated that 34.4% of the population was
overweight, 24.9% obese and 5% diabetic (Eathington 2008).

landcoverSprawl and a monoculture of a few land uses are a rising concern by researchers. Part of this
concern is the ever larger expanses of lawn and larger single family homes. Below the GIS
analysis of the urban case study has found that 4,500 acres of manicured lawn, grasslands,
and agricultural land exists within the city limits. This excludes floodplains and steep slopes
because for ecological reasons it is important that these areas area protected and kept intact.
If one assumes that only half of these 4,500 acres are productive it still means that about
2000 acres of underutilized land could possibly be used to support the fruits and vegetables
demanded by the Ames population.

current urban food system flow diagram
As for the urban case study of Ames there is many issues and opportunities present in both
Story county and the city. Interviews have concluded that producers are stable and wanting
to expand but land prices and the lack of local processing restricts their growth. The local
controls, policy and structure is in a stable but flexible state. Land development concerns
are presently related to urban growth and the ample amount of underutilized land. City
departments though are concerned about expanding the current small community garden
program to a much larger community wide system.
Aside from the physical and productive sectors of the current food system food access and
health is a serious concern both in the county and city. As the food system flow diagram
represents below there is very few points of food access for community members. This is
both a concern for the consumer and the producer as the distributor and the processor has
much of the control over the system. The producer has very few points at which to market
new products after a production expansion. Producers also have few local sources to process
meats and for added agriculture. Valued added means to process vegetables and fruit into
sauces, jams, and other additives through canning, drying, freezing, etc.
Even though there are many issues, analysis of landcover and land use within the city limits
represents a high amount of potential of meeting the citys fruits and vegetables demands
within the city limits. Earlier calculations determined that 970 acres for vegetables and 930
acres for fruit would be needed to supply the fruits and vegetables for 6 months of the year
for the citys approximate 2007 population of 55,000. As stated earlier the landcover analysis
found 4,500 acres of mown lawn, grassland and current agricultural land within the city limits.
This represents that there is an enormous potential of food production within the city of Ames.

the urban food system typology
The first step to organizing a city based on the theory food urbanism is to develop a land
inventory of the city. This report explains how a land inventory of the urban case study
allowed for the development of a typology and vocabulary of a productive urban landscape. As
part of the land inventory of the city of Ames potential sites were compiled that were classified
based on their size and potential user group. From these potential sites a typology was then
created explaining the characteristics of each type of food production within the theory of food
urbanism. This typology can thus be used to classify sites within future land inventories inother Iowa communities.
The following pages and chapters provide examples and tools in developing an urban food
system.

After creating a land inventory the urban food system typology can be used to classify sites.Each types then have their own attributes. The typology can also be used to help find a site
that meets a certain criteria. For example if a community organization is wanting to develop
a new community garden the typology specifies that the site needs to be under .5 an acre in
size. It will then be the organizations responsibility to manage that community garden based on
citywide policies of management. As specified in the typology, renters of plots in community
gardens have the option to utilize the ability to market their goods in the larger food system;
most typically at a farmers market. These members would be required to meet all inspections
as other producers and community members to be able to sell food at a market.
This example is the same if a municipality is interested in providing fruits and vegetables for a
higher percentage of the cities population. The city could meet this requirement either through
a new urban or neighborhood farm. They would then ask for RFQs from urban farmers that are
interested in managing the new proposed farm. This farm manager and their staff would then
have the requirement to provide community services such as farmer training or educational
courses for example on food processing.
The following 7 prototypes are examples of each type within the urban food system typology.The page leading each prototype explains the attributes of each. It is important to understand
how designers/officials of a local CADC would provide assistance in each instance of a new
prototype.

+Private Residence Garden
User/Producer/Stakeholder:
Managed by a private homeowner or independent user
Location/Scale:
All production will be provided by the landowner/user within the property boundaries. This
production is possible at many scales. An entire private residence could be retrofitted to
produce food or just the rear 20 ft of a lot could be managed.
Characteristics/Scenario:
Special instances that create prime scenarios to have a productive landscape as a homeowner
are large lawn expanses, the presence of an alley, large street setbacks and/or clear solar
exposure. Street setbacks are good examples because these spaces usually are not intended
for use but are meant to provide a visually pleasing setting on approaching the entrance.
Production Types:
The type of production and items being produced are dependent on the homeowner/users
ambitions/goals. Chickens, fish, and/or fruit and vegetables could be produced or managed.
These activities could be primarily within a greenhouse, a plot or multiple of pots, raised beds
or a combination of these and others.
Designers Role:
The designer would be able to assist in constructing or developing plans for a private
residence. Plans could be created that best utilize the entire property for food production.
Examples: using permaculture techniques to maximize production, rainwater harvesting,
circulation amongst production plots, or rotation plans. He/she could assist in developing
goals/objectives of an independent production operation.

+Community/Allotment Garden
User/Producer/Stakeholder:
Managed by a neighborhood organization. Plots rented to community members and managed
independently by renter. Rents are paid annually and set by the neighborhood organization incharge of management. The neighborhood organization will follow rules and guidelines created
by the local CADC.
Location/Scale:
The site of a community/allotment garden would be equal or less than an acre. The site
could be on private property, within a public park, on vacant land, or a school yard.
Characteristics/Scenario:
A community/allotment garden would characterized by a multiple of individual plots ranging
within a variety of scales. Plots are rented on an annual growing year for the private use of the
renter. Tools, storage, and composting would be managed independently or collectively based
on the structure created at the time of implementation of the community/allotment garden.
Water access and security would be provided as part of the annual fee to rent a plot. Security
would be provided by fencing and locked gates.
Production Types:
The plot could consist of food production and/or an ornamental garden. Production wouldbe within raised beds, plots, pots and/or on vertical surfaces. Production could be managed
independently for personal consumption/revenue or the community/allotment garden user
population could collectively market products for revenue.
Designers Role:
The designers role would be to assist in locating an appropriate site for a community/allotment
garden. Plans would be created based on the neighborhood organizations goals/objectives
or their garden space. The designer would organize the growing techniques, circulation,
materials, hardware and storage and composting systems.

+Food Blvd
User/Producer/Stakeholder:
Managed by a municipal, neighborhood or non-profit organization. Plots rented to community
members or local producer and managed independently by renter.
Location/Scale:
A food blvd is a street retrofitted or designed as a productive landscape. Prime scenarios of
streets that could be retrofitted are not arterial streets, do not have parking along them, are
excessively wide, have excessive parking along them, or are streets where parking is located at
the rear of the property. The scale of the productive landscape is dependent on the scale of the
food blvd.
Characteristics/Scenario:
A food blvds function is to provide a source of circulation for pedestrians and cyclists in
addition to a continuous productive landscape. A food blvd is able to more intensively use
a linear landscape that is designed primarily for the car. A food blvd can consist of multiple
scales as long as production and both modes of transportation are able to coexist. Fencing
or other trespassing measures would be dependent on the designer and the client of the food
blvd. Vertical growing walls could be used in instead of fencing as an example of other options
to create boundaries separating the different users of the blvd. All fencing or barriers though
are required to be transparent to allow for clear site lines of activities. Small structures meetinglocal food production guidelines are allowed but are provided by the builder.
Production Types:
The plot could consist of food production and/or an ornamental garden. Production would
be within raised beds, plots, pots and/or on vertical surfaces. Production could be managed
independently for personal consumption/revenue or for commercial marketing by a local
producer. In order for a food blvd to be farmed commercially the production space must
be larger than an acre. Dependent on the renter it would be their responsibility to supply
storage, tools, and composting facilities. Water access would be provided as part of the
design of the food blvd.
Designers Role:
The designers role in retrofitting streets would be to actively search out prime cases and
prepare plans for the local CADC. Designers and developers would have the responsibility to
implement food boulevards. Cycle and pedestrian lanes, fencing and/or other mechanisms of
creating edges to the production spaces are the responsibility of the developer and designer.

+Institution
Non-profit Institution
User/Producer/Stakeholder:Owned/rented by a non-profit organization. Production is managed and organized by the non-
profit organization that owns/rents the land or in agreement with a local producer.
Location/Scale:
A non-profit productive landscape is a productive landscape that is either owned or rented by
a non-profit organization. Dependent on the goals/objectives of the non-profit organization the
amount of production will be determined.
Characteristics/Scenario:A non-profit organizations goal/objectives of food production would be based on the mission
of the association. After submission of a tax-exempt status, a cer tification as a non-profit, it is
the organizations responsibility to provide programs and services that are of public benefit that
are not otherwise provided by local, state or federal entities. Examples of possible services
would be farmer training, home food processing/cooking training, or housing. In addition to
these services the non-profit would produce foods and/or materials that would be consumed
internally or externally for example through a CSA.
Production Types:
Production would be within hot houses, rotational plots, aquaculture, raised beds, pots and/
or on vertical surfaces. Production could be managed independently for internal consumption
or for commercial marketing as part of a CSA, farmers market or a local food market. It would
be the non-profit organizations responsibility to supply water, storage, tools, and composting
facilities.
Designers Role:
The designers role would be to provide technical assistance and help in securing funding foroperations. Plans would be created based on the goals/objectives of the NPO. The plans would
layout the production operations dependent on the types of production.

Religious Institution
User/Producer/Stakeholder:
Owned by a religious organization. All production is managed and organized by the religious
institution and/or a local producer or other joint stakeholder organization.
Location/Scale:
A religious productive landscape is a productive landscape that is part of a religious
institutions grounds. Dependent on the goals/objectives of the institution the amount of
production will be determined. In order for a local producer to have all or some part of theresponsibilities in managing production the site must be greater than an acre.
Characteristics/Scenario:
A religious organizations goal/objectives of food production will determine the scale of
production possibly determined by how the produce will be marketed and/or consumed. The
institution could also provide the services of farmer training, home food processing/cooking
training just as a non-profit organization. Produce foods and/or materials that would be
consumed internally or externally for example through a CSA.
Production Types:
Production would be within hot houses, rotational plots, aquaculture, raised beds, pots and/or
on vertical surfaces. Production could be managed independently for internal consumption or
for commercial marketing as part of a CSA, farmers market or local food market. It would be
the organizations responsibility to supply water, storage, tools, and composting facilities.
Designers Role:
The designers role would be to provide technical assistance and help in securing funding foroperations. Plans would be created based on the goals/objectives of the organization. The
plans would layout the operations dependent on the types of production.

Education Institution
User/Producer/Stakeholder:
Owned by a private/public school/university. All production is managed and organized by the
institution and/or a local producer or other joint stakeholder organization.
Location/Scale:
A school/university productive landscape is part of the institutions land. Dependent on the
goals/objectives of the institution the amount of production will be determined. In order for a
local producer to have all or some part of the responsibilities in managing production the sitemust be greater than an acre.
Characteristics/Scenario:
The school/university goal and objectives of food production will determine the scale of
production by how the produce will be marketed and/or consumed. The institution could also
provide services for example as farmer training or home food processing/cooking training.
Produce foods and/or materials would be consumed externally or for example internally in a
school dining center.
Production Types:
Production would be within hot houses, rotational plots, aquaculture, raised beds, pots and/or
on vertical surfaces. Production could be managed independently for internal consumption or
for commercial marketing as part of a CSA, farmers market or local food market. It would be
the organizations responsibility to supply water, storage, tools, and composting facilities.
Designers Role:
The designers role would be to provide technical assistance and help in securing funding for
operations. Plans would be created based on the goals/objectives of the school. The plans

User/Producer/Stakeholder:
Owned by a neighborhood organization, local institution, municipality or private landowner. All
production is managed and organized by a local producer.
Location/Scale:
A neighborhood farm ranges between 1-3 acres or equal to a city block. The farm would be
located within a residential neighborhood.
Characteristics/Scenario:
A neighborhood farm would be a source of food production and recreation. Playgrounds and
sports courts/fields would be required per neighborhood farm. Community members would be
allowed to assist in production with the local producer. Annual neighborhood organization dues
would supplement operation costs of the farm.
Production Types:
Production would be within hot houses, rotational plots, aquaculture, raised beds, pots and/
or on vertical surfaces. Production would not be limited to crops but also small livestock (ex:
poultry). Production could be managed for commercial marketing as part of a CSA, farmers
market or local food market. It would be the farms responsibility to supply water, storage,
tools, and composting facilities.
Designers Role:
The designers role would be to provide technical assistance and help in securing funding

User/Producer/Stakeholder:
Owned by a local institution municipal government or local landowner. All production is
managed and organized by a local producer.
Location/Scale:
A city farm would be greater than 3 acres or a city block. The farm would be located within
diverse urban area of multiple land uses. This would provide equal access by community
members and provide a substantial amount of fresh produce and goods to the community.
Characteristics/Scenario:
A city farm would be a source of food production and as a center for a farmers market or local
food processing hub. Playgrounds, sports courts/fields, trails, and other recreation could beadditional amenities per city farm. The local producer and farm management staff would be
in control of all operations. Annual municipal taxes would supplement operation costs of the
farm.

The proposed urban food system flow diagram represents how implementation of the
urban food system typology would increase food access points for community members.
Community members would have the option to purchase food directly from the farmer at the
farm store or by a share in a CSA. The consumer could also buy food at a neighborhood or
urban farm of their choice. The consumer could then also go to their favorite grocery storeor farmers market just as they do today. In the proposed food system there will be a greater
quality of local products since local producers, neighborhood farms, urban farms, institutions,
and allotment renters all have the ability to market their goods at a store.
By increasing the number of access points of fresh products food insecurity will be reduced
and food deserts will disappear. The transparency and resiliency of the local food system will
be much stronger than the current conventional food system.

the urban food system typology in the futureurban fabric
Market Blvds would be implemented before new development begins. The market blvds would
be implemented by the local CADC along with sewers and storm systems. Developers would
be required to pay up-front for any infrastructure costs. Within new development all developers
would be required to implement the urban food system typology and the typology of circulation
within the future urban fabric. The local CADC would create new guidelines for private
development. (Ex: New urban private developments must provide growing plots for more than
50% of all residential units that do not have access to 100 sq ft of private outdoor space (City
of Vancouver, B.C.)). The following typology of streets would fit within a block structure of
250wide blocks for pedestrian and bicyclist circulation and 500 wide blocks for auto and
transit circulation. Pages 51-58 represent the urban food system typology implemented into
the typology of circulation within the urban fabric of a hypothetical site.
Typology of Circulation
Market blvd major ar terial for transit, emergency, and bicyclist circulation incorporated along
a continuous productive landscape organized into community/allotment gardens and/or plots
managed by local producers. Outdoor markets and activities associated are the core of market
blvds.
Major Arterial for auto and transit circulation; typical section dependent on traffic capacity
Minor Arterial for auto, transit and bicyclist; typical section two lanes + bike lanes; max.
speed 35 mph
Local Street local auto and bicyclist; circulation barriers limit use of local street to auto for
more than four blocks; typical section one-two lanes + bike lanes; max. speed 25 mph
Food Blvd pedestrian and bicyclist; food blvds function is to provide a source of circulation
for pedestrians and cyclists in addition create a connection to the nearest market blvd.

The circulation diagram above for the typology of circulation represents the levels of traffic
intensity on each type of circulation. By implementing this typology the core of the 250
blocks is much more pedestrian friendly. The food blvds are protected from vehicular trafficand create a continuous landscape that connects areas of the community together create a
walkable community. The food blvds, local streets, and market blvds would provide safe routes
to school. The diagram represents how a market blvd is the core of pedestrian and bicyclist
circulation. Each are able to safely reach a market blvd with very little confrontation with cars.

Just as important as any piece of the urban food system typology guidelines would require that
private development use edible landscaping and provide private outdoor space to a required
percent of residential units. Private residence owners could supplement their vegetables andfruits with those they grow in their own yard.

Just as guidelines for new development would require a set percent to be for private outdoor
use; community gardens could be a form of this requirement. Community/allotment gardens
would allow individuals to work and socialize together while working on each others plots.

The food blvd is the heart and soul of the pedestrian and bicyclist movement. Instead of
walking along a busy street and a harsh building edge pedestrians can follow a food blvd and
purchase items at market stands along the food blvd. The food blvd would create a safe routefor children walking to school.

The institution would provide a long list of services to the community including beginning
farmer training, home food processing classes, and etc. The institution would range in scale
depending on the institutions site and mission statement.

Neighborhood farms with the capability of supporting 112 people with their fruit and
vegetables would be an enormous asset to neighborhoods. In addition to producing food
neighborhood farms would also be a community park. By connecting neighborhood and urbanfarms together to active parks with food blvds a continuous productive landscape network of
alternative routes would be created. The neighborhood farm would provide many community
services and also be busy with activities.

The urban farm would be like a city park with bike trails, wildlife areas, playgrounds, and active
recreation fields and courts. As part of these activities food production would be intermixed in
the web of activities. A family would be able to spend an entire day at an urban farm becausethey could have breakfast at the restaurant in the farm and spend time helping the farmer pick
apples in the morning and then play soccer as part of an organized league in the afternoon.

Every piece of the urban food system typology implemented together in this diagram begins to
represent the continuous productive urban landscape that begins to form. Forget the car today
and maybe the bus and walk over to the community garden and work for an hour and thenbike along the food blvd and hit up Garys market along the market blvd since he said he would
have carrots this morning.

the potential of an urban food systemEarlier landcover analysis has created signs that an urban food system has a huge potential
but how many people could a typical urban or neighborhood farm and a community garden
plot support? The Economic Research Service within the U.S. Department of Agriculture
annually publishes per capita demands of fruits and vegetables. Calculations can decipher the
potential of a urban food system.
As tools both for producers and local CADCs there are two ways of calculating the capita thatcould be supported by a specific scale of production. The following calculations on the next
page are examples of each and are based on tomatoes and potatoes grown on a 5 acre urban
farm. The first example calculating the potential of an urban system based on yield + scale
of production is inefficient. As the example shows two different sizes of groups of consumers
have to be marketed to be able to sell all the potatoes and tomatoes grown on an urban
farm to prevent waste. In this example a producer or grocerer is able to market potatoes and
tomatoes to 252 people both at the same time. This means that when a consumer comes to
the urban farm or grocery store they can purchase both their potatoes and tomatoes that they
demand annually. There is still tomatoes remaining after all the potatoes have been sold. Now
a producer or grocer needs to find and market just tomatoes to another 414 individuals. This
requires more time and money on their part.
The second example calculating the potential of an urban system based on the demand +
yield ratio is the correct and most efficient way of calculating the potential of an urban food
system. Opposite from the first example calculations are now based on the demand and yield
ratio rather than only yield. By basing calculations on this ratio a producer is able to determine
a specific amount of land that should be designated to a certain crop so that after marketingall the grown product there is very little or no amount of a certain product left over. This saves
money and time and prevents waste. Appendixes C-E are spreadsheets that would assist a
CADC official or producer in calculating the potential of a known scale of production.

The graphics on page 61 represent the potential of a 5 acre urban farm, 2.5 acre neighborhoodfarm and a 300 sq foot community garden plot. Calculations were based on the demand and
yield ratio example from page 60 and were based on the fruits and vegetables represented
within the graphic on page 61. These calculations represent a large potential of both the urban
and neighborhood farm and support the assumption that a 300 sq foot community garden
would only be able to provide just below half of the vegetables needed by an individual.
The graphic below represents how the potential of the urban and neighborhood farm can be
used to inform an urban food systems potential. The city of Ames 2007 population minus
the approximate 8,500 students that live within ISU dorms, was 46,245. thus to support 50%
