This thesis presents the landscape architecture design, Woven Suburbia Project.

The Woven Suburbia Project implements ecological, social, and agricultural vegetation

corridors into existing suburban neighborhoods. Corridors are composed of retrofitted

individual residents’ front yards and street edges, and are designed through the

collaboration of a landscape architect and the suburban residents. Woven Suburbia

Project responds to the rapid building methods of Post-World War II suburban

development by implementing design elements that support community, local

production, and environmental restoration. The design also takes inspiration from three

contemporary design movements that work to bring ecological landscape systems into

existing urban and suburban development. Ten steps to create a suburban corridor are

outlined for a landscape architect to follow, so that this framework can be replicated for

suburbs across the country. The redesign of La Costa Knolls, in San Diego, California

will demonstrate how to execute the ten steps of the Woven Suburbia Project.

Introduction

The sun rises over the glistening golden meadow grasses. A gray squirrel leaps

from the meadow and onto the sheltering oak tree. It scuttles up the strong trunk to fill

its cheeks with acorns, startling the mocking birds nested within. The birds cry their

song that tells the neighbors that it is time to wake. The man in the white house is

always the first person to stir the stillness along the street, for every summer morning he

harvests fresh berries from his front yard for an early breakfast. The animal chatter and

daily landscape changes make him proud of the vitality that has been brought into this

suburban neighborhood. He recalls when his harvest included a fifteen-minute drive to

the grocery store. Now, he gets to ponder the poppies, slowly meander with old friends,

and delight in the moment when fresh peas can be snapped from the vine.

This picture of an ecologically, socially, and agriculturally vibrant neighborhood

demonstrates a potential outcome from the Woven Suburbia Project. The foundation of

this thesis will explore why and how the Woven Suburbia Project can help any

suburban landscape to achieve the healthy ecological, social, and agricultural qualities

of the countryside. First, this thesis will contextualize the Woven Suburbia through the

exploration of Post-World War II suburban development. Secondly, it will explore three

contemporary design movements that work to bring landscape systems into existing

urban and suburban development. Next, it will outline ten steps that a landscape

architect can take to design a Woven Suburbia Project. Lastly, this thesis will apply the

Woven Suburbia Project to the suburb of La Costa Knolls, in San Diego, California.

The first portion of this thesis will show how after the Great Depression and

World War II there were drastic societal changes that drove the population to make

quick decisions about how to build America. People were hoping to see improvements

for their country after the tragedies they had witnessed for two decades. This life was

enlivened by intense economic growth, primarily created through urban and suburban

growth and development. This portion of the thesis will demonstrate how the federal

government approached this need for a radical change by creating policies to support

the creation of millions of single family residential homes, centered around the new

development of housing and infrastructure production techniques and the pent-up

demand for housing.1 Many other values that were previously respected in America,

such as community and the environment became less important. As a result, the

intentions for home-centric development drove the country toward intentions of profit

and commodity, with the result of environmental degradation.

The second portion of this thesis will show how in the intervening years, the

values of environment and community have grown more robust. Three contemporary

design movements are currently working to bring community and nature into the hands

of the public by introducing community design, the production of local resources, and

the environmental restoration to the areas developed during post-war times.

The third portion of this thesis proposes Woven Suburbia Project as a means to

introduce community design, the production of local resources, and environmental

restoration into existing suburbs. For, the suburbs are a developed landscape that has

not been carefully researched and explored for retrofit and redevelopment by

contemporary designers. To achieve the goals of the production of local resources and

environmental restoration, the Woven Suburbia Project will focus on the introduction of

productive social, ecological, and agricultural corridors to augment and enrich existing

suburban yard and street space. To achieve the goal of community, the suburban

redesign will follow a process that can help design the neighborhood with hands-on

work from both the landscape architect and from the suburban residents.

The last portion of this thesis will illustrate the Woven Suburbia Project by

applying it to La Costa Knolls, a small suburb located about 30 miles north of

downtown San Diego, California. La Costa Knolls was built in 1985 during a time of

sweeping development of single-family residential homes in San Diego County. The

land which previously supported a hilly chaparral community alongside an oak

woodland creek now supports 61 two-to-three-bedroom single-family homes with

paved streets, concrete sidewalks, and grass lawns. There is no homeowner’s

association, community center, or parks. There is a hilly chaparral restoration area near

the development, which offers an opportunity for connection between the suburban

neighborhood and the native ecology. The application of the Woven Suburbia Project

for La Costa Knolls will bring healthy social, ecological, and agricultural corridors to

the neighborhood.

Part I. Post-WWII Suburban History

In his 1996 novel, Holy Land: A Suburban Memoir, D.J. Waldie poetically

recollected his life in a suburban neighborhood.2

He notes:

“You leave the space between the houses uncrossed.

You rarely go across the street, which is forty feet wide.

You are grateful for the distance.

It is as if each house on your block stood on its own enchanted island,

Fifty feet wide by one hundred feet long.

People come and go from it, your parents mostly and your friends.

Your parents arrive like pilgrims.

But the island is remote. You occasionally hear the sounds of anger.

You almost never hear the sounds of love.

You hear, always at night, the shifting of the uprights, the sagging of ceiling joists,

And the unpredictable ticking of the gas heater.” -271

One by one, the descriptions in this passage demonstrate missing links in many

Post-World War II suburbs. Single-family homes have often become isolated and

poorly built; nature has transformed into very wide streets and grass lawns; the daily

community often consists of barking dogs, yelling voices, and the occasional passer-by.

As demonstrated through D.J. Waldie’s poetic dissatisfactions with the suburbs, there

were many essential human needs that were explicitly forgotten in the development of

millions of single-family suburban homes.

As noted by Dolores Hayden in her book, Building Suburbia, pre-WWII

suburban life was based in the ideals of home, nature, and community, so that suburban

life “encompassed both the private and public pleasures of peaceful, small-scale

residential neighborhoods.” However, Hayden illuminated how after the post-WWII

economic expansion, “the residents’ hope of unspoiled nature fails because open land

vanishes with increased development,” and “their hope of community is betrayed when

tracts of houses, hyped as ideal ‘communities,’ lack social and economic centers, parks,

schools, and necessary infrastructure.”3 Thus, ‘home’ is the only element of the triple

dream that fits into the post war American lifestyle, because of how the production of a

home and its economic benefit supports the American drive to boost the economy.

The Great Depression and World War II were societal triggers that influenced

this sharp change in the progress of American suburbs, making the conditions noted by

Waldie a suburban reality. As noted by Becky M. Nicolaides and Andrew Wiese in The

Suburb Reader, in ‘Postwar America: Suburban Apotheosis,’ the depressed economy at

the end of these two major events created a drive for the sad and war-ridden population

to make a radical shift in its actions to create a healthy and vital home life. A radical

economic, social, and political change needed to happen so to bring Americans back

into a lifestyle that supported their twentieth century needs.

Nicolaides and Wiese explore how the federal government approached the need

for a radical change by creating policies to increase the economy through the creation of

millions of single family residential homes. These policies had a strong foundation

because of the timely new development of housing and infrastructure production

techniques and the pent-up demand for housing. This analysis demonstrates how the

political drive that focused on the increased economy replaced the need for community,

replaced local resources and quality for manufactured goods, and led to the building of

millions of homes over abundant precious natural areas, causing devastating

environmental degradation.

During the last years of WWII, the pent-up demand for housing was staggering;

1945 marked the sixteenth year in a row that new construction did not meet the demand

for new housing. It was not uncommon for Americans to attempt to convert cars,

chicken coops, and barns into family housing.4 Nicolaides and Wiese note how the

intensity of the housing need was due to the increasing economy, the returning war

workers and veterans to urban areas, and the desire of veterans to settle down and start a

family.5

There were many options that developers could have taken to satisfy this great

need for housing, such as the development of multi-family homes, improvement of

urban conditions to infill cities. Developers could have even designed with a greater

likeness to community-and-nature-centric suburbs developed just 30-years earlier, such

as Ebenezer Howard’s Garden Cities6, John Nolen’s Mariemont7, or Frederick Law

Olmsted’s Riverside8. However, internal economic and demographic pressures through

lobbyists, politicians, and developers specifically supported a policy for the

development of single-family suburban homes.9 These policies offered no economic

incentive for developers to build amenities for the sake of the community, such as

parks, community centers, or natural areas.

Between the mid-1920s and the mid-1950s, five types of legislation were

enacted to encourage the building of single-family home suburban real estate. These

included: The Federal Housing Administration and Veterans Administration programs

for mortgage loan insurance; homeowner mortgage interest deductions; interstate

highway subsidies funded by gasoline taxes; and tax deductions for accelerated

depreciation on commercial real estate.10 These provisions of subsidies and changes on

taxes allowed the government to focus their spending on private goods, as opposed to

the more democratically oriented tactic of public spending. Thus, environmental and

cultural considerations in the development of infrastructure, education, and

transportation were overlooked, and the quick and efficient production of individual

homes was put on a pedestal. In other words, the government used the manipulation of

the public’s subsidies and taxes to make it in everybody’s economic interest to focus on

the consumption of home-centric products.11 Hayden even considered the

government’s role as “a propaganda effort, a coalition of over seven thousand local

growth machines composed of bankers, builders, and manufacturers supporting

government aid to private real estate development as a national economic strategy to

boost consumption.”12

Thus, after the end of WWII the increase in single-family home development

was staggering. “Whereas only 142,000 housing units were built nationwide in 1944,

just two years later builders were hammering up over a million homes annually, 1.9

million by decade’s end.”13

The production of quick and cheap home development techniques supported the

desires of the federal government to enhance private spending. Thus, taxes and

subsidies were created to support technologies and machinery.14 Factories were

developed that could quickly manufacture building materials; advanced bulldozers were

produced that could quickly level natural vegetation and topography to create flat lots.

Dolores Hayden noted how, “Lumber companies had mastered mass production so that

the scale of house-building was conceived in terms of tens of thousands of units, even

hundreds of thousands of units.”15 All parties found that it was highly profitable to

create standardized homes with these techniques.

Because of the exiting new possibilities for a ready-made lifestyle, suburban

Americans became very interested in having middle-class homes that were made with

the latest models of products. Nicolaides and Wiese noted how, “Middle class status

came to depend…on possessions and way of life—what a person consumed and how he

behaved were more important than what he did for a living. In this milieu, suburban

home ownership became an important badge of middle-class status. If you lived in a

particular place, owned a home, and fit in, you were considered middle class.”16

For example, an advertisement from 1950 for suburban homes in Tucson,

Arizona appeals to the masses through a large headline proclaiming the deals on homes

through GI Loans and no down payment. The advertisement then lists 22 specific home

products that were all manufactured at a distant location from the homes, such as

weather-stripped doors, asphalt tile floors throughout, electric exhaust fan, and cement

front walk.17 This advertisement’s explicit mentioning of 22 household goods as

encouragement for someone to purchase a home demonstrates the importance of

owning a home with all of the latest household items.

Due to the mechanized process of post-war suburban development, untrained

entrepreneurs such as bankers, builders, and brokers were able to take on a role as

suburban land planners. As real estate historian Marc Weiss notes, a suburban land

developer, “designs, engineers, finances, develops, and sells an urban environment

using as the primary material rural, undeveloped land.”18 These developers were not

interested in designing a neighborhood for the qualities of a vibrant and natural

community, but rather to create profit through the development of as much buildable

land as possible.19

Thus, precious qualities such as topography, natural drainage, plant and animal

ecologies, and soils were simply seen as barriers to the rapid development of single-

family homes. As noted by Girling and Helphand in Yards, Streets, Parks, “Subdivision

developers commonly stripped sites of all vegetation prior to grading and constructing

roads. They filled marshes and culverted stream-ways in an effort to maximize

buildable land. By the time residents moved in, all traces of the natural landscape were

obliterated and replaced with roads, driveways, houses, and lawns.”20 Nature had

mostly been replaced with natural abstractions of curved roads, pastoral rectangular

lawns, and street names such as “Park,” “Forest,” “Hills,” “Meadows.”21

The subdivision of Levittown, built in 1949 by the Levitt brothers in Long

Island, New York, exemplifies the post-war interest of creating profit-driven suburban

developments. At that time, Levittown was the largest subdivision in America with

6,000 homes sprawled across miles of historical agricultural land. During Levittown’s

infancy, anxious homeowners were interested in settling down into a ready-made

neighborhood with all of the amenities of a quaint and family-oriented life. Girling and

Helphand compared residents to “pioneers arrived en mass, much like the participants

in a gold rush, finding a ready-made community to fulfill their desires for a home of

their own and more.”22

As noted by Dolores Hayden in her essay, “Building the American Way: Public

Subsidy, Private Space,” the standardized development of the Levittown homes

streamlined the home-buying process, allowing buyers to quickly purchase a home,

create a family, and begin to support the national economy through work. Every home

was almost identical, with 800-square-feet designed with a living room, kitchen, two

bedrooms, one bath, and a driveway. Sometimes the only notable variation was a picket

fence versus a rail fence.23 Alfred Levitt compared the process of standardized homes to

the manufacturing of a car, where “each part will fit any house of the same model.”24

There was little need for the residents to make decisions in the creation of a home, for

the intention of the time was to fit into the status-quo and follow the accepted patterns.

The Levitts did not consult topography, ecologies, existing uses, or community

needs in their design, but rather saw the land as individual plots each worth a certain

amount of money. In fact, the Levitt brothers did not look toward any methods of

planning in their development of thousands of homes. They had no sewage disposal

system, neighborhood council, education system, or place for commerce. Further, the

massive road system was not integrated with the surrounding highways.25 These

systems and technologies could have realistically been planned into the environment,

for they had been implemented and understood by the 1940s, demonstrating the Levitt

brother’s lack of interest in bringing nature or community into Levittown.

Other suburban developments that followed Levittown certainly included a few

more principles of planning. However, design moves that related to community and

nature were often removed from the plan so to decrease costs, whether by moving

houses closer to the streets to save on piping, removing parks and planting strips, or

combining sidewalks with curbs.26

Effects from government policy during Post-WWII suburban development are

still working in America today. The creation of personal economic growth often

overrides community growth. The creation of manufactured commodities often

overrides local production. The devastation of natural landscapes is the consequence of

these values.

It is imperative that new forms of urban and suburban development are

considered so that America can house the ever-increasing population. Hayden notes,

“there is no way Americans can create tens of millions of units of affordable housing

without preserving existing places and supporting their ability to serve current residents

as well as to absorb infill housing…. Where there are places with existing houses,

25 Ibid. 26 Ibid.

13

existing public infrastructure, and existing community networks (forged over years of

propinquity), there are strong social reasons to rehabilitate as well.”27

The next portion of this thesis will explore three contemporary design

movements that are working with the existing fabric of urban and suburban areas to

replace the individual needs of economic growth with community, manufactured

commodities with local resources, and to restore a healthy ecological environment.

Part II. Contemporary Design Movements

The following explorations of Food Not Lawns, Continuous Productive Urban

Landscapes, and Green Infrastructure creates a bridge between the aforementioned

Post-WWII private development values, and the design of the Suburban Corridor

Project. Each of these three contemporary design movements retrofit the urban and

suburban fabric of post-war development with ecological methods. Each of the three

movements works at a different scale, from individual yards, all the way up to entire

urban and suburban regions, creating unique solutions relative to their context. Each

movement uniquely informs the Woven Suburbia Project.

Food Not Lawns

Food Not Lawns is an example of a neighborhood scale contemporary design

movement that aims to improve existing urban and suburban developed areas, through

an intimate community, the production of local resources, and environmental

restoration. Food Not Lawns is a grassroots movement driven by the actions of the

individual members of the community, that focuses on using lawns or other unused

plots or corners in urban areas to grow food. H.C. Flores, author of Food Not Lawns:

How to Turn Your Yard into a Garden and Your Neighborhood into a Community, notes

how “Growing food is the first step toward a healthier, more self-reliant, and ultimately

more ecologically sane life...when we take control [of food] back into our own hands,

we empower ourselves toward autonomy, self-reliance, and true freedom.”28

28 Flores, H. C. Food Not Lawns: How to Turn Your Yard into a Garden and Your Neighborhood into a

Community. 2. Print.

15

Founders of Food Not Lawns were inspired to provide knowledge and passion to the

individual because of their observance of great flaws in contemporary American urban

and suburban development. They noted how urban areas were designed for residents to

move away from their communities through the use of cars, making people escape

friends, families, and community-supportive jobs. Flores questions, “How do we begin

to disconnect from the pressures and ugliness forced into our lives, and to reconnect, by

choice, with the people, places, and things that give us joy?”29 The founders quickly

noticed how resource heavy grass lawns could be easily transformed into a garden for

food production, in other words, a place to reconnect with the ecology of nature and the

community.

The goal of Food Not Lawns is to inspire the individual to create an organic and

productive garden, however and wherever it will grow. They believe that an

individual’s effort will ideally inspire another member of the community, ultimately

creating a strong chain of individuals using their own hands to grow their own food.

Flores believes that the only way to start the change is to begin within the local

community and to spiral outward to greater populations.30 Physically, this process can

be as simple as giving away abundance from gardens, whether in the form of extra

produce, seeds, shared labor, or knowledge. As opposed to the precedent of privately-

driven development, Flores believes in a more egalitarian attitude of “embracing a role

Community. Forward. Print. 30 Flores, H. C. “Ecological Design.” Food Not Lawns: How to Turn Your Yard into a Garden and Your

Neighborhood into a Community. 161. Print.

16

as willing participant, rather than master and commander, of the garden and surrounding

ecology.”31

The founders also saw Food Not Lawns as a method to step away from commodity

driven lifestyles, through the production of ones’ own goods. Food Not Lawns outlines

hundreds of gardening, design, and storage methods so one can create their own food,

medicine, and building materials, and support the greater ecology through clean air and

water. The process of learning methods to produce one’s own goods opposes the post-

WWII commodity driven lifestyles, where factory production highly obscured the

consumers understanding of the product.

Further, Food Not Lawns believes that the process of ecological restoration is driven

by the personal production of goods. The creation of soil, planting of trees or crops, and

harvesting and use of these goods highlight the healthy and unhealthy environmental

consequences in the neighborhood and surrounding areas. Thus, the individual becomes

educated about how to better treat the urban or suburban environment, and is then able

to enact environmental changes, such as the elimination of pesticides, the planting of

appropriate trees or shrubs, or the reduction of driving.

Food Not Lawns takes a subtle approach to relinking the community, resources, and

ecology throughout urban and suburban areas. Although there is certainly power in how

one individual can influence the actions of a community, the process of taking public

action against the private-profit driven development process needs to have a more

31 Ibid.

robust structure to make the kinds of change as desired by the founders of Food Not

Lawns.

Continuous Productive Urban Landscapes

Continuous Productive Urban Landscapes, or CPULs, is an example of an urban-

scale contemporary design movement that aims to improve existing urban and suburban

developed areas, through an intimate community, the production of local resources, and

environmental restoration. CPULs, created by Katrin Bohn and Andre Viljoen, promote

the development of a coherently planned thread of open spaces that will connect the

inner-city, through the suburbs, and out to the countryside. The thread will attach

existing urban parks, gardens, forests, and other gathering spaces, to newly acquired

land for urban agriculture. Bohn and Viljoen in their book, CPULs: Continuous

Productive Urban Landscapes note how, “CPULs will read as parks or urban forests,

green lungs or wilderness, axes of movement and journey, or places for reflection,

cultural gathering and social play. They will be containers for an assembly of various

activities that do not happen in buildings.”32 Most importantly, CPULs will be a place to

grow food, so to cultivate community, local resources, and to ecologically restore

unused urban spaces.

A primary goal of Continuous Productive Urban Landscapes is to make visible the

productive resources required to support profit and commodity driven urban and

suburban lifestyles. CPUL spaces will be designed to expose urban dwellers to

“activities and processes traditionally associated with the productive countryside,

32 Viljoen, Andre, Katrin Bohn, and J. Howe. Continuous Productive Urban Landscapes: Designing

Urban Agriculture for Sustainable Cities. Oxford: Architectural, 2005. 11. Print.

18

thereby re-establishing a relationship between life and the processes required to support

it.”33 These processes include the growing of food, the planting of diverse trees and

water cleaning vegetation, and the management of land. From these activities of

beautification and the creation of ecological biodiversity, services are created such as

greenhouse gas reduction, improvement of water and air quality, noise filtering, the

creation of a local food system, and a space for social activities and education.

Continuous Productive Urban Landscapes will perform a unique form of urban

ecological restoration by interweaving urban agriculture throughout a city, without

having to erase urban tissue or create a tabla rasa. Thus, CPULs will inevitably be

inspired by and responsive to the existing fabric and culture of a city.34 The designers

who will obtain the land for CPUL plots will have to creatively reclaim greenfield or

brownfield sites, un- or under-used plots or streets, parking lots, or any other roof or

sidewalk that is not being used to its full potential. The renters or owners of the lot will

then have the responsibility and choice to integrate the ecological function that best

suits the site conditions, whether agriculture, park space, or native plantings.

The goal of CPULs is to integrate the organization and power of urban planning

with the culture of the local communities. The movement has not yet created a clear

procedure to follow to obtain the thread of land from the inner-city to the countryside,

but ideally, the organization of urban planners, landscape architects, and other parks or

19

landscape officials can work with eager individuals and communities so to obtain and

manage the appropriate spaces.

Often, the designer focused approach to urban planning leaves out the local people

and focuses on projects that support the status quo of profit-driven projects.35 However,

the design of CPULs recognizes the importance of offering “ownership and control to

local people to manage their environments as they choose.”36 In general, local

occupants will rent out the individual parcels of land and manage the production of food

on the lot. As noted by Simon Michaels in “Urban Food Growing: New Landscapes,

New Thinking”, this process will allow for inventiveness and personalization in the

city.37 Interaction between plants, water, soil, animals, neighbors, and communities

often found through the creation of spaces for urban agriculture, is hardly ever captured

in development through traditional urban planning.

Continuous Productive Urban Landscapes takes a broad look at how a system for

community driven agriculture and ecology can greatly enhance both urban and

suburban areas. Bohn and Viljoen note how “suburbs offer generous open spaces, views

to the horizon and access to sunlight, whereas city centers thrive due to a compact

arrangement of cultural and social venues.” CPULs work to create a threaded landscape

so that “suburban dwellers gain a pleasant walk to work,” and “city dwellers get a walk

into the countryside, like a weekend escape.”38

Despite the authors’ desires to utilize the opportunities and constraints of both urban

and suburban landscapes, their focus lies in the denser urban areas of a city, as opposed

to the suburban areas. It does not seem like the concepts laid out for dense urban areas

would thrive in the spread out and heavily privatized landscape of the suburbs.

Green Infrastructure

Green Infrastructure is an example of a landscape-scale contemporary design

movement that aims to improve existing urban and suburban developed areas, through

the production of local resources, environmental restoration, and community. The

definition and scale of green infrastructure varies widely in contemporary planning,

design, and restoration conversations, however, the intentions often hold the same value

of introducing and conserving vegetated areas to deliver healthy urban services.

To define green infrastructure, it is important to clearly understand the role of

existing urban infrastructure. Currently, urban infrastructure is primarily made of man-

made and engineered elements to quickly transport elements such as water and sewage

away from the city, as seen in the form of concrete gutters, sewers, pipes, and other

devices.39 Further, urban infrastructure is also made up of elements to quickly transport

people, such as asphalt streets and concrete sidewalks. The goal of green infrastructure

is to replace some of these hard elements with vegetation that can filtrate, beautify, slow

down, and diversify the ecology of urban and suburban areas within the city itself.

Thus, I bring together Webster’s Dictionary definition of ‘infrastructure’ and the

broad definition of Green Infrastructure in Tzoulas et al.s Promoting ecosystem and

human health in urban areas using Green Infrastructure: A literature review,40 to create

a definition of Green Infrastructure for this thesis: All natural, semi-natural, and

artificial networks of multifunctional, and multi-scalar ecological systems that create

the substructure or underlying foundation for an urban or suburban area.

As noted by John W. Dover in Green Infrastructure: Incorporating plants and

enhancing biodiversity in buildings and urban environments, the services of a green

infrastructure will help to support the production of resources, without having to leave

the city.41 These services often come in the form of supporting services, nutrient and

water cycling, soil formation, primary production; regulating services, climate control

and pollution removal; provisioning services, food, medicines, building materials; and

cultural services, societal appreciation of nature and environment.42 The addition of

these services will transform dense urban areas into environments with healthy,

meditative, and transparent resource use.

Green Infrastructure restores natural ecological processes with various methods at

multiple scales, including home, neighborhood, suburbs, dense urban area, and out to

the city edges. As defined by Mark Benedict and Edward McMahon in Green

Infrastructure: Linking Landscape and Communities, “at the parcel scale, green

infrastructure means designing homes and business around green space, and include

walking or nature trails... At the community level, green infrastructure could mean

creating greenways to link existing public parks. At [the broader scale], it could mean

protecting broad landscape linkages that connect forests, prairies, and other natural

areas and provide habitat for animals.”43 At an even finer scale, Dover believes in the

importance of the smallest scale elements of green infrastructure, such as green roofs,

green walls, and street trees, to contribute to ecological urban services.44

For large-scale change to occur in an urban and suburban area, intensive top-down

planning strategies are required. However, because of the nature of the intensive

management necessary for vegetated infrastructure, it is important that all types of

business, government, citizens, and nonprofit organizations are involved in the planning

and management of these designs. Benedict and McMahon note how “Regardless of the

scope of a green infrastructure initiative, success is achieved locally; successful leaders

build broad stakeholder support through a consensual, open, fair, and transparent

process.”45 Benedict and McMahon note how residents and other stakeholders should

have the opportunity for input, feedback, and participation in the implementation of the

green infrastructure network.46 Because of the large and ever-changing scale of green

infrastructure, there are endless opportunities for expertise from different types of

experience and education.

Green infrastructure is the quilt which weaves together the various components of

urban and suburban areas. It takes hundreds, if not thousands of people to collaborate to

create a system that supports a healthy, clean, and functioning city. That said, it is a

very broad vision that will never have a clearly defined beginning or end point. It is

always in flux and will have to respond to unseen environmental, economic, and social

factors as they come. I believe that the most effective way to build up to the goals of

green infrastructure is to begin work at the community scale, with reference to the

smallest and largest pieces that sit at the edges of that community. Designs at the

community scale are more likely to make a visible impact, as the ecological, social, and

infrastructural relationships can be traced and learned from, and then scaled up to meet

the goals for an ecologically vital urban and suburban experience.

The analysis of the contemporary design movements of Food Not Lawns,

CPULs, and Green Infrastructure demonstrates how there are some areas of the urban

and suburban patchwork that are not addressed. Physically, the systems within the less-

dense, single-family home suburban areas have not been widely addressed in these

contemporary design movements. There are few formalized design methods about how

to retrofit these areas into community driven, locally productive and environmentally

healthy places. Socially, there are few systems that have collaborated simultaneously

with the residents of the area and a designer such as a landscape architect, to envision

and redesign a developed urban or suburban area. The physical form of the suburbs and

the social relationship between residents and designer complement each other, for the

24

suburbs serve as an expansive canvas for individual residents to design their yards, and

the landscape architect to weave these yards together.

As demonstrated through the Food Not Lawns movement, suburban areas often

have un- or under-used land from front yards, that would serve as a perfect place to

locally produce goods and improve ecological function. The front lawns also have great

potential for social activation, as they are highly visible to all members of the

neighborhood. As demonstrated through Continuous Productive Urban Landscapes,

there is a great need to expose and physically connect the methods of production,

especially that of food production, often associated with the countryside in urban and

suburban areas. In a method that involves both the residents of an area and a designer,

the creation of the physical connection will make corridors that are essential to

reconnecting the ecological, social, and transportation tissue of development. As

demonstrated through Green Infrastructure, there needs to be immense improvement in

the entire ecological structure of development from the dense urban core all the way

through to the outskirts of the suburban area. Many ecological design elements of urban

water infrastructure, streets, and park space fitting into the framework of Green

Infrastructure have been implemented in dense urban areas. Also, many conservation

and restoration projects fitting into the framework of Green Infrastructure have taken

place at the edge of cities in more natural areas. Fewer of these elements have been

executed in between these two extremes in the less-dense, single family home suburban

areas.

The next portion of this thesis will propose a new design process that fills these

gaps, through a design process that will take place in the front yard and street space of

25

suburban developments, with a system that works simultaneously with the residents of

the area and a landscape architect.

26

Part III. Woven Suburbia Project

The premise of the Woven Suburbia Project stems from the need to bring

vibrant communities, healthy ecologies, and locally produced goods into developed

areas that are lacking in these amenities. Currently, there are approaches to bringing

these qualities into denser urban areas. However, there are not many developed

processes that successfully bring these qualities into less dense single-family home

suburban areas. This design will focus on the suburban landscape that covers much of

American soil. Because the foundation of the suburban landscape stems from the

individual drive to own a plot of property, this design process will respect and utilize

the individual’s desire to manage their own plot of land. Further, due to the disparate

open spaces created because of the individualized intentions of the suburbs, there will

also be a landscape architect involved in the process so to insure that the individual

management of plots all seamlessly fit together in an ecologically, agriculturally, and

socially productive landscape.

Suburban landscapes have been defined in many different ways throughout their

development. For this design, the precise understanding of a suburb is not crucial. The

key element that needs to be present for the design process to work is to have a

neighborhood with mostly single-family residential homes with un- or under-utilized

front yard space. Further, it would be helpful if the neighborhood has a surplus of street

space so that a portion of it could be re-developed for the creation of suburban

corridors.

The ideal size for this form of suburban redesign should be from about 60-100

single-family homes. This size is intimate enough so that that landscape architect can

27

get a clear understanding of the culture, ecology, and resource use of the neighborhood.

Further, this scale can realistically make visible the processes of production that are

often associated with the countryside through the growth and sharing of food, the

capturing, saving, and reuse of water, and the improvement of the soils. On the other

hand, 60-100 single-family homes are large enough so that the work of the individual

residents can be connected into a corridor of ecological and social processes.

The goal of this design project is to weave vibrant ecological, social, and

agricultural corridors through small suburban neighborhoods. Characteristically,

suburbs have a low-density and un- or under-utilized yard and street space, making

them well suited places to insert ecologically abundant vegetation, socially vibrant

meeting spaces, and agriculturally productive gardens. These corridors will help to

promote spaces for the public through environmental restoration, community driven

spaces, and the production of local resources. Ecological, social, and agricultural

corridors are the most appropriate corridor types for suburban neighborhoods, for they

help to counteract the private interests that were ever-present during much of suburban

development that supported a profit and commodity driven society at the cost of

environmental degradation.

A landscape architect should follow ten detailed steps to ensure that all of the

essential processes are completed to create a healthy suburban neighborhood. The

process of designing is not linear, and each of these steps should be interwoven and

repeated when necessary. The organization of these steps responds to the hierarchy of

scale of understanding from the broadest scale of design, down to the finest.

28

The ten steps are as follows:

1. Understand Greater Site Context and History

2. Understand Adjacent Social and Ecological Areas

3. Map and Analyze Social and Ecological Conditions of Site

4. Design Qualities of Social, Ecological, and Agricultural Corridors for Suburb

5. Provide Plant Palette for Corridor Typologies

6. Design Ecological Streetscape

7. Design Unique Regional Identities Within Suburb

8. Interview Residents in Neighborhood Region

9. Help Residents Design Front Yards

10. Educate Residents about Impact of Production on Resource Use

1. Understand Greater Site Context and History

Once a properly sized suburban neighborhood to redesign is chosen, landscape

architect should work to thoroughly understand the general site context of the

neighborhood. It is important to understand the greater ecology of the region. Especially

note the intricacies of the region’s water patterns, for every design decision such

vegetation types, drainage, water capturing, and shelter, will depend on these weather

patterns. This knowledge will ensure that the vegetation and creatures can thrive with

the implemented infrastructures.

29

Further, the designer will also need to understand the social history of the region

that led to the initial development of the suburb. As noted by Dolores Hayden in

Building Suburbia,

“Interpretation of the history of suburbs is a powerful tool to support reconstruction. Public

history can convey the long ideological battle between the suburbs as places of aspiration and hard work

and suburbs as places of segregation, stratification, special interests, and profiteering… Local history can

help to define a positive sense of place in older suburbs by identifying important local victories and

establishing landmarks, such as a crusading local newspaper or a volunteer nursery school. It can show

the need for more democratic approaches to community development by revealing how hard residents

have worked to create a sense of solidarity when places were new and raw.”47

This history can help to elucidate when, why, and how the residents moved into

the neighborhood, thus educating the landscape architect about how to approach the

community in regard to retrofitting their neighborhood. It is important to note whether

the residents seem open to this idea of change, for it is more appropriate to begin the

process of retrofitting suburban neighborhoods with residents that are open to change.

Once the movement has begun, it will be easier to demonstrate the positive effects to

the skeptical suburban areas.


Step 2 brings the designer to a finer scale of site understanding, by looking at the

land uses adjacent to the suburb. At this scale, the landscape architect notes the adjacent

site’s drainage systems, soils, sun/shade, topography, ecological land covers,

surrounding developments, proximities to stores, transportation systems, and open areas

47 Hayden, Dolores. “The Importance of Older Suburbs.” Building Suburbia: Green Fields and Urban


30

such as parks and recreation. The designer will map the opportunities and constraints

for each of these qualities.


In Step 3, the designer will analyze the site of the suburban development of 60-

100 homes. Here they will note the same qualities as in Step 2 including: drainage

systems, soils, topography, ecological land covers, surrounding developments,

proximities to stores, transportation systems, and open areas such as parks and

recreation. It is crucial that the designer diagram and overlay each of these site

conditions, to obtain a strong and clear understanding of the social and ecological

conditions and relationships of the site. It is useful in this step for the designer to map

the opportunities and constraints for each of these qualities.

4. Design Qualities of Ecological, Social, and Agricultural Corridors for Suburb

In Step 4, the landscape architect further analyzes the results of the site’s

opportunities and constraints and determines which type of social, ecological, or

agricultural elements need to be woven into the corridors of yards and streets to connect

the disjointed systems. For example, the designer may note how the ecological corridor

is lacking clean water, leading the designer to consider water filtration through the use

of stormwater plantings. The social corridor may be lacking areas for community

gathering, leading the designer to consider turning yards into spaces for events. For the

agricultural corridor, there may not be a store to buy groceries at a walking distance,

leading the designer to implement local food growth on the site. Each suburb is

inherently unique and complex, demonstrating the importance of having a landscape

31

architect to note and orchestrate all of the retrofit details. The designer should make a

schematic diagram of how the elements needed fit together in the site’s surplus space.


In Step 5, the landscape architect more deeply identifies the needs of the

ecological, social, and agricultural corridors through the designation of plant palettes for

each typology. It is important that there are specific plant palettes for the neighborhood

so that the plantings will thrive and provide health to the surrounding native ecologies,

so that there is a continuous and maintained aesthetic throughout the neighborhood, and

so that the residents can be educated about the natural ecological processes.

Joan Nassauer’s article, “Messy Ecosystems, Orderly Frames” expands of the

idea of the importance of a continuous and maintained aesthetic to the neighborhood.

Nassauer notes, “People seek information about other people when they experience the

landscape,” so it is important to place, “unfamiliar and frequently undesirable forms

inside familiar, attractive packages.”48 The clean aesthetic through a consistency of

vegetation types will allow the ecological or agricultural plants to be vital and

productive, while still appearing well kept. This will allow the neighbors to respect the

amount of care taken in their other neighbor’s yards.

Further, the types of plants chosen for the plant palettes will result in a certain

education for the residents about natural ecological processes. For example, in

specifically looking at the agricultural palette, the initial choices may consist of food

plants that residents are very accustomed to eating, but are more than likely not

48 Nassauer, Joan I. "Messy Ecosystems, Orderly Frames." Landscape Journal 14.2 (1995)

32

accustomed to growing. These plants may not serve the best purpose for the native

ecologies around the site, for most popular crop plants are not native to most places in

the United States. However, the process of the residents growing these crops will create

a deeper understanding and relationship with these plants. And perhaps, with that

understanding, people will be open to replacing their non-native crops with something

more appropriate to the region.


Step 6 involves retrofitting the existing streetscape with uses that will support

the ecological, social, and agricultural corridors. Many suburban streetscapes were

designed with too much space for parking, no designed space for human interaction,

and concrete storm drain infrastructure. The landscape architect should thoroughly map

and diagram the existing streets of the suburb for its parking needs, water drainage

systems, and relationship to social space. Consider the street’s opportunities and

constraints and design a corridor along the road that corresponds to the site’s ecological,

social, or agricultural needs.


Step 7 is a process that helps both the designer and the residents understand the

unique elements built into the suburb. With an area of 60-100 homes there will

inevitably be different social and ecological conditions throughout a site, whether

influenced by microclimates, topography, relationships to ecologies, or proximities to

entrances, cul-de-sacs, or gathering areas. Each condition will allow for differing

relationships between the ways the residents interact.

33

In Step 7, the landscape architect divides the suburb into regions relative to their

social and ecological conditions, and gives each of the regions a name relative to their

conditions. This activity helps the resident to conceptualize where their home fits into

the greater whole of the suburb, and it helps to create a common conversation about the

most appropriate use of the designable space between neighbors.


Step 8 creates an intimacy between the landscape architect and the suburban

residents. Once the landscape architect fully understands the site conditions of the

whole site and the relationship between regions, it is important that they communicate

their findings from their context mapping and analyses, to educate the resident about

more obscure social and ecological qualities of their yard.

Simultaneously, it is important that the landscape architect ask the resident

questions about their interests in ecological, social, or agricultural landscapes. The

designer can ask whether they have an aesthetic preference, whether they have interest

in spending time and energy on managing a yard, and whether they have any experience

in managing an ecological space, a gathering space, or an agricultural space.

It is important to note that there will be a wide variety of interests and

backgrounds in any suburban neighborhood. Thus, it is important that there are a variety

of yard options that accommodate people with little to great interest in managing an

agricultural, ecological, or social yard.


34

In Step 9, the landscape architect works with the individual residents to design

their yards, so that the yard meets the aesthetic and functional needs of the individual

resident, and the needs of the greater ecological, agricultural, and social corridors.


In Step 10, the landscape architect educates the residents about the potential

resource impacts of the productive systems that they have implemented, so that the

residents’ can learn about the nuances of water savings, local food production,

ecological urban services, and other social, economic, and environmental processes.

Because of the rapid and profit-driven development of many suburban areas,

many resources were depleted, unplanned for, or hidden by developers during their time

of development. It is important that the landscape architect plans for methods to expose

these hidden resources, so to reveal the processes that are often associated with the

countryside.

Methods of education can be developed in a variety of forms including hands-on

work with resource production, identification of ecological processes and changes

throughout the suburb, quantification of water use, quantification of food grown in a

given area, or the tracking of economic changes through the adaption of resource use.

35

Part IV. The Woven Suburbia Project: La Costa Knolls

To more clearly explore the design process of the Woven Suburbia Project, the

next portion of this thesis will follow the ten specified steps to retrofitting corridors into

a specific suburb of La Costa Knolls in Southern California.

1. Understand General Site Context and History

Border of Mexico

Downtown San Diego

Figure 1

North County San Diego

Figure 2

36

La Costa Knolls is a small suburb located about 45 miles north from the border

of Mexico, and a 30 miles north from downtown San Diego, as shown the context map

of San Diego County (Figure 1). It lies 5 miles in from the Pacific Ocean, and sits at

the base of a range of rolling hills, as shown by the context map of North County, San

Diego (Figure 2). The region supports a chaparral ecosystem, which is defined as a plant

formation characterized by evergreen woody shrubs with short, hard leaves that rely on

periodic stand replacing wildfire. The most common chaparral species is Adenostoma

fasciculatum or chamise.

Despite the beauty of this golden landscape, it provides very few resources for

the booming population that Southern California now supports. The most important

lacking resource is water. California has an intense and unpredictable relationship with

water. There can be years of drought, or there can be intense flooding events. The design

of La Costa Knolls will take into account these oppositional weather conditions through

the drainage, vegetation, and social designs.

38

The progression of aerial photographs of La Costa Knolls and the adjacent land

uses in the years 1948, 1990, and 2016 demonstrates the site’s change over time.

In 1948, the landscape of La Costa Knolls was a sprawling, low chaparral

vegetation that grew from the edge of an oak woodland stream.(Figure 3)

The 1980’s arrived with a major push for suburban development in San Diego

County. In just ten years, acres of chaparral land was converted to hundreds of suburban

single-family residential homes.(Figure 4)

In 2016, the spaces that were able to be graded to an acceptable slope have been

filled in with homes, while areas of steep grade still show signs of the chaparral and

woodland vegetation. There is also a grocery store, a sports park, and a high school

within a five-minute drive of the neighborhood. (Figure 5)

39

Figure 6 shows an image of a home in La Costa Knolls. It has very similar

qualities to the rest of the 61 homes in the neighborhood, with a front lawn and

driveway connecting the street to the garage and front door. However, there are many

differences between homes that make them unique and distinct from each other.


Figure 6

Ecological Conditions

Figure 7

To get a clear idea of how each home differs, Figure 7 shows the maps of the

social and ecological conditions that affect the qualities of each home. The social

maps designate places of social encounter, such as the corner lots, and cul-de-sacs,

the entrance, and central areas. The ecological maps designate the neighborhood

conditions of water, sun, shade, and slope. With these maps, the landscape architect and

the residents will be able to pin-point their home, and then overlay these maps to fully

understand the specific social and ecological conditions of their front yard.

cultural corridors that the designer will aim to achieve through the redesign of La Costa

Knolls. These conceptual corridors respond to the conditions of the individual residents’

yards and to the drainage along the edges of the streets.

4. Design Qualities of Social, Ecological, and Agricultural Corridors for Suburb

42

Figure 9 shows a conceptual map of the social or gathering corridor that the

landscape architect will aim to implement in La Costa Knolls. Due to the lack of

community gathering spaces and un- or under-used open land in La Costa Knolls, this

design makes an effort to transform certain residential front yards into community

gathering areas. Ideally there will be some naturally sunny areas and some naturally

shaded yards for gathering. These gathering yards should then be connected through

gathering nodes on the corners of streets and pleasant and vegetated walking corridors

along the street-side swales.

Figure 10

Figure 10 shows a conceptual map of the ecological corridor that the landscape

architect will aim to implement in La Costa Knolls. The corridors respond to the

adjacent native ecologies of oak woodland and chaparral by directly connecting the

edges of the neighborhood corridor into the natively vegetated areas. The ecological

plantings will string through the front yards of sunny and shaded yards as appropriate.

The ecological corridor will also have an important role to play in the street retrofit, for

the storm water plants will be native and help to clean the water, while also tying the

street edges into the ecology of the neighborhood.

44

Agriculture

N 1’=1/64”

Figure 11

Figure 11 shows a conceptual map of the agricultural corridor that the landscape

architect will aim to implement in La Costa Knolls. Through the observation of the

yards of La Costa Knolls residents, there are a few small food gardens in residents’

back yards, but there is no public or front yard agriculture in the neighborhood. Thus,

most of the residents of La Costa Knolls drive to the grocery store to purchase their

food. It is important for this design to weave food systems back into people’s lifestyles,

so to create a transparency in how certain foods are grown. This corridor will design

the front yards of many La Costa Knolls residents to support some form of agriculture.

Agricultural yards will need to be placed in sunny areas.

distribution between ecological, gathering, and agricultural yards.

Figures 13-16 show the various plant palettes created for the respective

ecological, social, and agricultural systems. Each of these palettes contains mostly

native California species that grow in chaparral, woodlands, and prairies ecosystems.

The Ecological Stormwater Palette consists of plants that thrive with both

wet and drought conditions. Further, these plants were intentionally selected for

their compatible aesthetic that would create a beautiful swath that will enliven the

neighborhood.

and agricultural species. The landscape architect will encourage the residents to line the

edges of their yards with formal pollinator plantings to create a sharp, consistant, and

healthy edge aesthetic.

The Crop Palette consists of food plants that residents are very accustomed to

eating, but are more than likely not accustomed to growing. The designer will initially

promote growing the most popular crops, even if water intensive, for this experience

will allow the residents to gain a relationship with the food growing process. Ideally,

the resident’s relationship with the growing process of their favorite foods will create a

understanding of the time and resources that it takes for them to consume these foods.

Thus, residents will create a foundational understanding of how their food

consumption may relate to and affect the increasing water demands in Southern

California. And perhaps, with that change and understanding, people will be open to

replacing the thirstier crop plants such as cabbage and brussels sprouts with agave and

chia.

Figure 17 shows an image of how the streets of La Costa Knolls are currently

designed. The roadway is very wide with a width of 40 feet. Over half of that space

is given over to parallel parking, which is usually only about 25% utilized. Concrete

gutters meet the road, which then meet the 5’5” sidewalks, which then generally meet a

grass lawn.

Figure 18 shows an image of a proposed streetscape. The edges of the streets

are converted into ecologically-minded design elements. Half of the parallel parking

spaces are reserved for parking with permeable paving. The other half is converted to a

vegetated swale. These plantings should make for an enjoyable walking corridor.

Figure 20 shows the conceptual map that designates each region of La

Costa Knolls into a region with a unique identity. Each region experiences the

neighborhood with a unique social and ecological perspective because of the different

topography, social meeting places, views, adjacent ecosystems, water drainage, and

street intersections. The neighborhood is divided into eight distinct regions based on

their unique elements: The Gateway, The Woodland Terraces, The Raingarden, The

Woodland Cul-De-Sac, The Hearth, The Prospect, The Chaparral Cul-De-Sac, and The

Chaparral Terraces.

Figure 21 takes a close look at the conditions of the Hearth Region, to

understand the process of creating a design through the development of a regional

identity. The rest of the design process will focus within this area of La Costa Knolls.

Physically, the Hearth sits at the center of the neighborhood loop, making it a

natural gathering area where neighbors can comfortably meet, grow, cook, dine, and

greet. The Hearth gathers water runoff because it is located on a flat grade at the bottom

of a two steep slopes. It has five homes with full sun exposure, and three homes with

mostly shady conditions in the front yards.

Socially, most of the Hearth neighbors have known each other for about two

decades. However, there is very little spontaneous interaction, for the front door of the

home is paved to the front door of the car.

The next two steps will be repeated three times for each of the example yards

that will be redesigned.


Figure 22 shows Debbie Wirth in her front yard. During her interview she noted

how she enjoyed walking into her home past the clean and sharp aesthetic of the front

lawn. She also expressed an interest in creating better conditions to invite neighbors

over to share a meal or simply get together on a nice summers evening.

Figure 23 shows an image of the existing conditions of the Wirth’s front yard.

The yard is due northeast, creating shaded conditions. This will make a perfect place

for a shaded gathering area during the warm months. The Wirths also have an existing

representational streambed that does not actually convey water. Due to their location

at the base of a hill for water runoff, the stream should be transformed into a running

stream that can support native vegetation at the stream edges.

Figure 23

56

Based on the Wirth’s interests and home conditions, Figure 24 shows a

rendering of a design for their front yard. The typology of half of this yard is a gathering

area, based on Wirth’s interests to host neighbors and save her grass lawn. The lawn

will be a perfect place to for kids to play and adults to gather. The yard will also support

an ecological area, because of the natural drainage point of the yard. The visitors and

residents can sit in the shade of the existing home and palm trees and look out to the

neighborhood and to the healthy ecologies.

Figure 25 shows a site plan to further demonstrate the relationships between

the lawn, ecological area and the street edge. Figure 26 shows an example of how the

meadow plants can be applied to soften the yard’s hard edges.

Figure 27 shows Hina Mehta in her front yard. In an interview, Mehta noted how

she already has a vegetable garden in her backyard. She said, “Sometimes we just like

to pull up the chairs right next to the garden because then you can see the butterflies and

you can see your fruit and your beautiful tomato or whatever. So we go and pull up two

chairs right where the boxes are and sit there.” She then showed interest in pursuing

more edible food growth in the front yard, but she was also a bit wary of the messy

aesthetic that is often associated with food crops.

The Mehta Family

Figure 27

59


Figure 28 shows the existing condition of the Mehta’s yard. The northeast sun

exposure allows only half of the yard to receive enough sun to grow food. So, the

design will support agriculture in the sunny area, and refined ecological plantings in the

back shaded area of the yard.

Figure 28

60

Figure 29 is a rendering of a proposal for the redesign of the Mehta’s front

lawn. As you can see from the proposed image, the design very intentionally takes into

account Hina’s interest in a ‘clean’ agricultural aesthetic. The aforementioned article by

Joan Nassauer’s, ‘Messy Ecosystems, Orderly Frames’ informed the approach to this

issue.

This approach with ‘attractive packages’ appears in the perfectly aligned, walled

raised beds, and corresponding plantings of trees. The ‘orderly frame’ also appears

in the border of pollinator plants that hug each of the yards, regardless of typology.

The intention for the pollinator plants is to create a crisp and familiar edge, defining

the productive systems within each yard. The pollinator plants enhance ecology by

consisting of native flowering forbs and shrubs, enhance agriculture by supporting

pollination of food crops, and enhance social areas by providing beautiful color and life

for neighborhood residents.

Figure 30 is a site map that further demonstrates how the Mehta’s front yard can

create crisp relationships between agriculture, ecology, and existing front yard space.

The Meyers and the Ginns split the third redesigned yard right down the middle.

This arrangement provides differing design inspiration for the respective sides, while

also providing a great opportunity to physically weave two systems together.


Figure 32 shows the Ginns in their front yard. Twila Ginn recently converted a

corner of her backyard to a vegetable garden, and she has fallen in love with growing

produce. She is very excited about the idea of sharing food and educating people about

the process. She noted, “It’d be great if someone grew that, someone grew that, and

we’re all sharing the stuff in some sort of way. I think Tammy makes jelly from grapes.

Penny next door has chickens. I think everyone has that kind of mindset, but it would

take someone to organize all of it.”

Figure 33 shows Lori and Neal Meyers in their front yard. Unlike Twila Ginn,

Lori Meyers, would rather relax outside with a glass of wine. She is interested in

forming spontaneous happy hours, with neighbors driving home from work or walking

down the street.

The Meyers Family

Figure 33

Figure 34 shows the existing condition of the Ginn and Meyers yard. The yard

is sunny, flat, and at a central location in the suburb. These attributes make the yard an

optimal option for an agricultural and gathering space, where neighbors can meet to

farm, wine, and dine.

Figure 34

65

Figure 35 shows a rendering of a proposal for the redesign of the Ginn and

Meyers yard. This design demonstrates clean, hierarchical swaths of agricultural

plants with ample space for movement around the yard. Further, there is a border of

pollinator plants that edge the crops for cross-pollination. The gathering space sits right

in the center of the yard, so to make a welcoming and open space of gathering. It is

simply designed with a flat brick surface, so that neighbors can meet here for a variety

of reasons, whether being for spontaneous happy hours, vegetable processing, or a

neighborhood feast with the yield.

Figure 37-46 demonstrate two different methods to educate the residents about

resource use. Figures 37 and 38 show the number of people that could be fed from the

food able to be grown in the Ginn’s yard. Figures 39-46 show the water use for different

types of growing conditions in La Costa Knolls and the surrounding neighborhoods.

Figures 37 and 38 show the number of people that could be fed in the warm and

cool season from the food grown in the Ginns yard. These numbers were calculated by

finding the site’s square footage, the location of the crops varieties, and the resultant

number of plants. I then spoke to farmer friends to get a number for how many people

can be fed by each crop plant.

The numbers also demonstrate how this yard has the potential to feed more

than just the Ginn family. For example, the amount of summer berries could feed the

entire neighborhood region. The potential abundance and sharing of produce is a way to

catalyze the exchange of both goods and knowledge between neighbors.

Figures 39-46 demonstrate the impact of how the small reduction of water use

in one yard can influence an entire community. These figures show this by calculating

the change in water use from pre-design implementation to post-design implementation.

Water use numbers for each vegetation type, whether non-living ground cover, native

vegetation, agriculture, or lawn are taken from the calculations done by the San Diego

Water Authority. These numbers were then brought into a Geographic Information

System (GIS) and associated with front yard vegetation type. In GIS, each yard type and

resultant water use was equally distributed across these homes. The following series of

images shows the percentage of change from the existing popular yard type of the grass

lawn to the mixed use of ecological, agricultural, or social front yards for the scales of

the Hearth, La Costa Knolls, Adjacent Neighborhoods, and the Greater Neighborhood

Area.

Figures 39 and 40 show how the Hearth with 8 homes had a 36% water

reduction. Figures 41 and 50 show how La Costa Knolls with 61 homes had a 38%

water reduction. Figures 51 and 52 show how the adjacent neighborhoods with 392

homes had a 37% water reduction. And Figures 53 and 54 show how the greater

neighborhood, with 1616 homes had a 39% water reduction.

Figure 45 demonstrates the Greater Neighborhood’s water use numbers for non-

living ground cover, all native, and all agricultural yards. The comparison of these other

numbers demonstrates how much resource use can change with the introduction of a

new type of vegetation.

The education of water use through Step 10 will demonstrate how a resident can

alter their suburban lifestyle in the face of the intensification of the drought, or simply to

provide a healthier environment for oneself and one’s community.

CONCLUSION

The Woven Suburbia is a response to the elements of the contemporary suburban

environment that unsuccessfully serve communities of people or nature. Through the

addition of healthy ecological, social, and agricultural corridors, suburban developments

will be known for their ecological vibrancy, social centers, and local food production.

Within this thesis, the contextualization of Post-World War II suburban development

clarified the impetus for suburban developers intentions to quickly build millions of

single-family homes across the United States. The exploration of three contemporary

design movements that focused on bringing landscape systems into existing urban

and suburban development gave inspiration and direction for the design of the Woven

Suburbia Project.

Ideally, many landscape architects will be inspired to choose a suburban

neighborhood where they can implement the Woven Suburbia Project. The ten steps

will lead the designer into a strong relationship with the residents of the neighborhood,

so that there is great community involvement, leading the community to manage the

ecological, social, and agricultural corridors into the future.
