    ForewordOn behal o the Presidio Trust, I would l ike to express our gratitude or EDAW's

    excellent work on the Fort Scott Creek & Historic Gardens project. We were thrilled to

    have the Presidio selected as the ocus o EDAW's "usion" initiative or this year, and our

    expectations or both the design process and end product were more than exceeded.

    As managers o an incredibly complex landscape, we are continually challenged to strike

    a balance between competing demands -- rom ensuring that the park's environmental

    and historic treasures endure to providing memorable opportunities or the public

    experience [o] the Presidio. It was rereshing to have such a talented and dedicate d

    team come to the park and help us creatively explore new opportunities to balance

    and achieve these various mandates. It was a rigorous week, and we were all very

    impressed by the process and the outcome.

    In particular, I want to acknowledge the exceptional team that EDAW sent to the

    Presidio including Alma Du Solier, Alex Felson, Leo Edson, Debra Bishop, and Dawn

    Cunningham. They were an extremely dedicated and talented group o proessionals.

    We very much enjoyed working [with] them and I continue to receive positive eedback

    rom the many people who engaged with them over the course o the week.

    We deeply appreciate the contribution EDAW made in helping progress plans or the

    Presidio's uture, and we look orward to working with your talented sta again.

    Sincerely,

    In November 2006, a week-long workshop ocusing on both ecology and landscape

    design was conducted at the Presidio o San Francisco. The goal o the workshop

    was to develop conceptual design plans or the Fort Scott Creek + Historic Gardens

    project that would bridge the divide between ecology and design, and identiy applied

    techniques or this approach in the uture. We started with the assumption that

    designers and ecologists working together could produce better design solutions

    than those resulting rom more independent work patterns. We discovered that ourunderlying disciplinary assumptions, the tendency to rely on what we do best, and

    limited opportunities or ecologists to participate in the design process, all create

    challenges or usion among disciplines. At the conclusion o the workshop, the

    team was able to identiy moments o successul integration as well as missed

    opportunities or collaboration and develop a diagram depicting the dynamic. This

    book presents ndings about ways to acilitate interdisciplinary design and ecology

    work, describes the workshop collaboration and outcomes, and analyzes the process

    o designers and ecologists working together.

    Introduction

    What is more valuable in an urban park setting: public access to water or riparian

    wildlie habitat preservation and enhancement?

    Can public use and recreation be integrated with both habitat enhancement and

    controlled visitation?

    What takes precedence in a historic national park: ecosystem unction or

    historic preservation?

    Key Questions

    How can one ensure that opposing stakeholders reach a winning consensus rather

    than everyone eeling that they have given up too much?

    In the summer o 2006, two landscape

    architects, a wildlie biologist, and a

    restoration ecologist rom EDAW teamed

    together to orm an initiative exploring

    the usion o ecology and design. The

    EDAW team approached the Presidio Trust

    in search o a pilot project or the rmsEcology and Design Initiative. EDAW has

    viewed the usion o ecology and design

    as a undamental aspect o its work or

    decades. This unded eort emerged rom

    conversations between EDAW ecologists

    and designers seeking to elevate ecological

    design to a higher level throughout the

    rm a level where meaningul ecological

    unction and value is incorporated into the

    design on multiple projects.

    The Presidio Trusts commitment to

    achieving a balance between the parks

    environmental and historic treasures, and

    its past success in completing projects that

    incorporate meaningul restoration ecologywith public use and design elements. This

    bridging o ecology and design indicated

    a natural t or the initiatives pilot project.

    For the ocus o the workshop, Presidio

    Trust sta proposed the Fort Scott Creek +

    Historic Gardens site. The site is slated to

    become a uture Center o Engagement

    ocused on sustainability.

    With the goal o exploring the dilemmas

    and opportunities o interdisciplinary

    design, the team participated in a

    one-week site-based visionary and

    consensus-building workshop or the

    Fort Scott Creek + Historic Gardens.

    Collaborating with the Presidio Trust,EDAW sought to achieve a balance

    between enhancing public uses

    and conserving the parks valuable

    environmental and historic resources.

    This partnership with the Presidio Trust

    enabled EDAW to explore the intricacies

    o stakeholder dierences and site

    constraints. Applying ecological and

    design lenses to the Presidio, the EDAW

    team exposed a number o key challenges

    in the integration o these two disciplines,

    and acilitated a process o exploration or

    resolving these conficts.

    A key goal on our part was to acilitatecommunication and idea exchange

    through planned discussions and

    inormal interactions such as site walks.

    We organized the week's schedule to

    oster a continual dialogue between

    the designers and ecologists (Fig. 1-2,

    Integrating Design

    and Ecology

    The increasing demand or sustainable

    urban designs, green building, and

    green inrastructure requires a deeper

    ecological understanding o urban

    environments. While ecologists currently

    contribute to the design and construction

    o cities as consultants on design teams,urban ecology remains a fedgling eld

    with weak theoretical underpinnings and

    a limited shared vocabulary.

    Most ecologists today avoid human-

    dominated environments, ocusing

    instead on sites that are not primarily or

    human use. Ecologists are happy i they

    understand a system, while designers

    aim to invent something new. When

    ecologists do get involved in design,

    such as through restoration ecology,

    they typically employ a naturalistic design

    aesthetic and work toward hiding any

    evidence o the human hand. This

    contrasts with the goal o designers, who

    oten want to make a project visible.

    One key issue to address in dening

    urban ecology is what role people,

    technology, and the political and socio-

    economic aspects o human society play.

    Most existing quantitative research

    investigates ecology in cities, ocusing

    primarily on plant, animal, water and

    nutrient fows occurring in urban

    settings, while avoiding the challenge

    o translating political, cultural, social

    and economic actions into ecological

    terms. People and the city are viewed in

    these cases as external orces aectingbiological conditions.

    Ecology o cities takes a more holistic

    view o human society and its interace

    with biological processes, looking at the

    ecological implications o socio-cultural,

    political, and economic urban patterns.

    Various methods used to measure inputs

    and outputs o a city include system

    metabolism at a variety o scales:

    building, neighborhood, watershed, city,

    or region. Urban ecology also examines

    the spatial distribution o these scales and

    the circulation o people and materials

    (Spirn 1984).

    Unraveling the ecology o urban

    environments and translating people

    and culture into ecological terms may

    not be so easy. Unlike more natural

    environments, cities are the result o

    human design rather than the product

    o millions o years o evolutionary and

    biogeograph ic processes. EcologistsFigure1-3 Human-Nature Diagrams

    investigating cities ace the dicult task

    o incorporating the physical, cultural,

    economic, and political urban terrain

    into their research and analysis. This

    requires not only grappling with a number

    o variables never beore dealt with in

    ecological research, but also developing aposition on what urban ecology includes

    and excludes, and understanding to what

    degree human patterns are ecological

    (see Fig. 1-3, Human-Nature Diagrams).

    Fundamental conceptual questions

    remain. Should humans be thought

    o (like other biological organisms)

    as ecological actors? I so, can we

    consider our manuactured systems

    (such as HVAC or zoning) ecological?

    What weight or value should human

    and biological infuences that shape

    urban spaces be given (see g 1-4

    -- Mapping Urban Ecology)? Can natural

    areas remain unctional as healthy

    ecosystems while also allowing

    human uses?

    Without understanding interactions

    and eedbacks between human and

    ecological systems, our view o

    ecosystem dynamics both at local and

    global scales will be limited as will be

    our ability to apply these insights to public

    policy and land management.

    (Grimm et al., 2000).

    The ambiguity o "ecology" as it occurs

    in human-populated environments, and

    the lack o terminology or ecological datadescribing the ecology o buildings, urban

    space, and other human constructed

    landscapes thwarts eorts to bridge

    disciplines. To help dene this usion

    zone, a new vocabulary along with a

    series o metrics based on viable empirical

    data needs to be developed. Pre sently,

    the lack o denition or documentation

    o the new ecological conditions created

    in urban environments make it dicult

    or designers to absorb ecological

    understanding into the design process.

    In order to access a greater range o

    ecological approaches, designers need

    to go beyond environmentalism and

    prescriptive design techniques, and take

    greater advantage o ecological science.

    While green design is becoming

    increasingly important to government

    agencies, clients, investors, developers, and

    designers, all parties are still working with

    limited knowledge o what actions will

  • 8/14/2019 Presidio Fort Scott Creek + Historic Garden_EDAW_Felson

    12/55

    20 21

    lead to sustainable development. Once

    implemented, questions still remain on

    how to maintain and operate the systems

    to provide prolonged sustainability.

    Ecologists also lack extensive, rigorously

    tested research about the unction

    o urban ecosystems -- includingdense urban, suburban, exurban, and

    browneld sites. Oten, in the absence

    o sucient inormation, designers must

    make educated guesses. Given the

    uncertainty and diculty o predicting

    uture outcomes o dierent strategies,

    developing eective sustainable practices

    requires testing and monitoring to ensure

    accurate inormation about the success

    o systems being implemented. More

    rigorous and long-term research o urban

    ecological processes and patterns is

    necessary to evaluate the ecological

    impacts o the various developments

    occurring in managed sites.

    Ecologists have the potential to make

    signicant contributions to urban

    design practices. They have already been

    contributing to the design and construction

    o cities through their roles as consultants

    (applied or restoration ecologists and

    ecological engineers) on design teams.

    Still, addressing urban ecology remains a

    new rontier, not least because current

    theories that dene cities and human

    activities in ecological terms are relatively

    rare. Today, ecologists and designers

    have an opportunity to bridge the gap

    between ecological analysis and urban

    design to reorient society towards a moresustainable uture.

    Incorporating ecological research

    components into urban development is

    a crucial part o advancing sustainability.

    Not only will it provide opportunities or

    a growing population o ecologists to

    establish research sites.

    A key goal to this usion eort is to

    develop enduring solutions. These

    vibrant and long-lasting designs could be

    evaluated or perormance and adapted

    overtime or eciency.

    Contrasts between the

    Ecological Science and

    Design Proessions

    While there is growing interest in

    bridging the gap between practices

    to acilitate green design and urban

    ecology, designers and ecologists dier

    in signicant ways that could slow the

    process. Designers and ecologists rely

    on dierent skill sets, approaches, andtechniques to explore and comprehend

    complex sites. The se dierences lead to

    a lack o dialogue or to communication

    breakdowns. While designers direct a

    creative energy towards realizing human

    experiences o a landscape, ecologists

    typically use a quantitative process or

    understanding specic environmental

    processes and patterns (Fig. 1-5).

    Despite the unique paradigms o these

    two distinct proessions, todays land-

    based challenges require integrated

    approaches and inputs to solve complex

    problems. Solutions need to arise not

    only rom an overlapping o disciplines,

    but rom a consistently integrated

    dialogue between ecologists and

    designers. This broadening scope o

    opportunities demands new approaches

    and input provided by interdisciplinary

    teams. In particular, the study o

    urban areas and other human-modied

    landscapes requires knowledge o

    ecosystem processes as well as o the

    physical, cultural, economic, political, and

    ecological complexities o urban systems.

    Fig. 1-4 conceptually illustrates how high

    design and rigorous science might overlap

    to provide a usion zone. Integration

    o these approaches requires a candiddialogue where dierences are exposed

    and goals are revealed at the start.

    Collaboration and commitment to dialogue

    are essential. The usion zone represents

    synergy, wherein all parties participate and

    are prepared to discuss concerns or ideas

    reely at any point.

    Recognizing the need or an understanding

    o how to acilitate design and ecology

    collaboration, EDAWs Client + Practice

    Initiative has provided support or a

    multidisciplinary group to team with a

    client and explore novel situations. The

    Presidio Trusts need or consensus-

    building among stakeholders provided

    a perect partnership opportunity or

    exploring how the synergy o design and

    ecology could help overcome obstacles to

    achieving interdisciplinary solutions.

    Ecologists have traditionally avoided

    human-inhabited environments.

    Designers modiy the environment to

    cater to human needs.

    Applied Ecologists Approach

    Process

    Grounded in Scientic Method: A s a

    science-based practice, ecologists attempt

    to adhere to a more objective approach,

    combining statistics, math, and computermodeling with biology, natural history,

    experimental research, and observation.

    Scale

    Individuals to Population or System:

    From micro-organisms to populations,

    communities, and landscapes, ecologists

    work at a broad range o scales in seeking

    to understand ecological dynamics.

    Scales are in part determined by where

    ecologists can identiy and interpret

    boundaries. The ecologists scale o work

    has traditionally been limited to the extent

    o the system or population studied. In

    addition, ecologists are oten nancially

    constrained or limited by the logistics o

    setting up large-scale experiments.

    Product

    Findings/Conclusions: The output o the

    scientic method is ndings or conclusions

    which negate or support a hypothesis

    based on the initial research question.

    Researchers conclusions are generally

    stated to specically answer the question

    and address the hypothesis. Interpretation

    and applicability o these ndings to other

    scenarios requires scientists to step outside

    o replicating experiments and to accept a

    level o uncertainty. Due to the unding and

    time constraints o conducting research,

    ecologists must oten predict and render

    judgment about likely outcomes

    and conclusions.

    Form

    Driven by Science: Form is based on

    statistical data and eciency. Experimental

    strategies developed over time that identiy

    boundaries raming complex systems, such

    as watersheds. Experiments typically use

    inexpensive materials with the simplest

    processes or capturing desired data.

    Restoration ecology is one o the ew

    examples where ecologists make design

    decisions. Oten the deault approach is to

    design in a naturalistic manner. Designers

    strong environmental stances as obstaclesto bridging the divide between the practices.

    Also, understanding the latest ecological

    theories and nding ways o integrating

    the scientic objective into design can be

    complicated (Fig. 1-6A).

    Making Concepts a Reality: Designs

    emerge through a process o understanding

    the site. Through a creative exploration o

    potential site experiences, constraints, and

    opportunities, designers produce solutions

    that are realized in drawings, images, and

    montages. Many scientists have diculty

    understanding the value behind these

    design methods, due to the use o

    subjective language, a ocus on aesthetics,

    and the design process (Fig. 1-6B).

    Scale

    A Parcel, Building, Park, or Regional Area:

    The land-based, surcial scale o work is

    dependent on the size and dened boundary

    Representation: Design is a representation-

    based approach, where designers utilize

    build human-related spaces and buildings.

    There is an increasing need or designers

    and ecologists to work at multiple scales

    to address the zone o usion between

    Ecologists are increasingly interested

    in experimentation, conservation, and

    restoration on urban sites, expanding rom

    their traditional presence in less human-

    dominated landscapes.

    Ecologists are broadening denitions

    o ecosystems, and (recognizing that

    ecological systems are continually being

    infuenced by disturbances) revising

    traditional vegetation theory to include

    multiple processes, human infuences,

    and spatial heterogeneity. Ecologists have

    also moved rom considering populations

    and ecosystems as relatively closed or

    autonomous systems, independent o their

    surroundings, to viewing both populations

    and ecosystems as open and strongly

    infuenced by input and output o material

    and individuals across system borders.

    Landscape architects have begun to take

    on a larger role in understanding and

    developing urban ecological systems.

    They are beginning to appreciate an

    ecological process-based understanding

    o landscapes and environmental concerns,

    Presidio as a Pilot Study

    or Ecology and Design

    The Presidio o San Francisco, a 1,490-acre

    park located at the Golden Gate Bridge,

    provides a rich context or exploring the

    collaboration between designers and

    ecologists. The Presidio is a distinct park

    site located at the center o the world's

    largest urban national park, Golden Gate

    National Recreation Area (75,500 acres).

    The Presidios mixture o land uses and

    competing stakeholder demands within

    an urban area has created a variety o

    obstacles to reaching consensus on land

    use decisions.

    In use as an active military post rom

    1776 to 1994, the Presidio was olded into

    the boundaries o Golden Gate National

    Recreation Area in 1972 ater being

    designated a National Historic Landmark

    District in 1962. Congress established The

    Presidio Trust in 1996 as a leadership body,

    and charged the Trust with preserving and

    enhancing the Presidio as an "enduring

    resource or the American public."

    The parks 300-acre Historic Forest is a

    designated historic landmark. The orest is

    recognized by many as a cultural landscape,

    shaped by the U.S. Army more than 100

    years ago, that signicantly contributes to

    the Presidios historic identity. Others view

    the orest as a created, articial community

    with limited diversity that replaced native

    dunes, coastal prairie, and coastal scrub

    communities. A highly charged discussion

    on this topic has been ongoing or years.

    Located in a highly urbanized center, the

    vast green spaces at the Presidio seem to

    be prime opportunities or diverse public

    uses. However, historic designations

    and stakeholders' interests oten create

    opposing demands. For example, the

    Presidio's buildings encompass 6 million

    square eet. Many o the houses that

    were once occupied by military amilies

    are now occupied by civilian amilies; there

    are nearly 3,000 people currently living in

    these homes. These long-term site users

    comprise a group o private stakeholders

    inhabiting space within a public park.

    Additional issues at the Presidio arise in

    relation to other land management visions,

    such as environmental restoration. These

    projects prompt a series o questions.

    What is the goal o restoration projects in

    an urban context? Which is more important:

    to restore a lands native ecosystem, or to

    cater to human needs and try to allow or

    some environmental value as well? In the

    case o the Presidio, there are a number o

    examples where restoration ecology proved

    a useul tool in bringing dissenting voices

    The Presidio Trust envisions the project

    site becoming an important destination or

    park visitors. Ultimately, the nearby historic

    buildings may be used or conerences

    and other events that could draw people

    with a common interest in addressing

    environmental and social issues. Historic

    structures and artiacts, many o which

    are yet to be restored, are common in and

    around adjacent historic gardens. From

    the gardens, a small spring-ed creek

    emerges and meanders along a valley that

    is itsel being restored to provide important

    ecological unctions and values. Planned

    native plant restoration will enhance

    opportunities or park visitors to view

    wildlie along Fort Scott Creek.

    The Presidio Trust challenged EDAW to work

    in a collaborative ashion with their technical

    experts to develop a conceptual design

    plan, which enhances, interprets, and

    integrates the unique eatures o the projectsite. The initiative was originally ocused on

    developing designs that incorporate ecology

    and design into public use, education

    and interpretation (Fig. 2-1A). As EDAW

    prepared and participated in the charrette,

    it became increasingly apparent that

    historic actors were a major infuence. The

    working model was expanded to integrate

    ecology, design, and history with public

    space (Fig. 2-1B).

    Key Requests rom Client:

    1. Develop a 21st-century approach that

    is sustainable, integrates state-o-the-art

    technology, and is respectul o the sites

    historic character.

    2. Develop the restoration o Fort Scott

    Creek and determine what role it might

    play in relation to other riparian corridors,

    as well as the historic landscapes.

    3. Knit the district together, and tie the

    historic garden and community garden to

    the ideas o sustainability and stewardship.

    4. Create an educational landscape with

    evolving experiences.

    5. Develop a landscape design that solves

    issues and creates opportunities or

    people moving through the site.

    6. Childrens activities are key. Make this

    a place where children in the Bay Area can

    enjoy a meaningul outdoor experience.

    7. Get people close to natural resources

    throughout the site to provide a sense o

    contact and intimacy with nature.

    Created by Congress in 1996, the Presidio

    Trusts mission is to preserve and enhance

    the Presidio as an enduring resource or

    the American people. Six presidential

    appointees and the Secretary o the

    Interior, or his/her designee, sit on the

    Board o Directors and set the direction

    and policies or the ongoing transormation

    o this historic military post.

    The Trust is charged with making the

    Presidio nancially sel-sustaining. Ater

    2012, the Trust will not receive annual

    appropriations, and is required to und the

    Presidios operations, maintenance, and

    ongoing upgrades with income earned

    rom rehabilitating and reusing the parks

    buildings. The Presidio is sustaining itsel

    like every healthy community earning,

    saving, and investing in the uture. This

    simple economy generates the capital

    that is making the Presidio a great national

    park and will ensure its preservation.

    As the largest urban national park in

    the world, nested within the Bay Area

    (population 12 million), the Presidio

    requires a unique resource management

    model, which blends competing local

    interests and needs with the broader,

    national constituencies supporting

    historic preservation, recreation, and

    environmental restoration.

    The Presidio Trusts mission (Fig . 2-3)

    illustrates the inherent challenges o

    planning, programming, and designing the

    site. Natural areas, wildlie, and native

    habitat are identied as key resources

    o the site which should be preserved

    and enhanced or public use. Historic

    structures and designed landscapes

    are also considered key resources to be

    preserved or the public. Ideally there

    will be diversity in the types o locations

    preserved at Presidio: both natural areas

    and designed landscapes. However, a

    process or reaching consensus is required

    or to achieve this delicate balance.

    Given site constraints, accommodating

    stakeholder demands will be challenging.

    Figure 2-4 illustrates the overlapping and

    competing interests in the Presidio as a

    national urban park. In particular, the role

    o preservation is embedded.

    Evolving Land Use

    A military presence can be traced to the

    Presidio as early as 1776. In spite o this

    human occupation o the site, until the

    early 1800s the Presidio eatured extensive

    sand dunes and coastal scrub extending

    across the coastal blus (see Fig. 2-5).

    Parts o the Presidio were also grazed

    especially during the Spanish occupation,

    leading to erosion and wind-blown sand,

    which was carried and deposited across

    the site. The US Army established a

    military post at the Presidio in 1846.

    In the 1890s, a decision was made to

    modiy the existing landscape in order to

    mitigate harsh winds, stabilize shiting

    sands, and complement the natural

    beauty o the land.

    Over time, the demands on the land have

    Community Gardens: Applying

    Historical Methods to Secure

    New Land Uses

    The debates surrounding community

    gardens at the Presidio are an apt

    illustration o the conficting demands and

    expectations placed on the land.

    The Presidios role as a community where

    people live and work, as a national park

    at the edge o a highly urbanized area,

    and its designation as a National Historic

    Landmark District lead to inevitable

    conficts. While community gardens are

    uncommon in national parks, they are a

    wonderul public use component o many

    urban parklands. They provide a venue

    or community members to invest in the

    land, they create habitat or insects and

    birds, and they can provide a means or

    maintaining the land (although management

    requirements may increase). The Nation al

    Park System acts as a stakeholder at the

    Presidio, oten nding its agenda in confict

    with the surrounding homeowners, Presidio

    inhabitants, and historic preservationists.

    Historically, the site was established

    as a pleasure garden or ocers and

    their wives along with the Fort Scott

    Creek area. Other gardens existed at

    the Presidio during its military period,

    including a victory garden and agricultural

    gardens used to grow ood or the war

    eort. The community gardens available

    at the Presidio today include one historic

    garden covering roughly a one-acre parcel

    o land. The well-established Presidio

    Native Plant Nursery also employs a

    signicant number o volunteers, providing

    avenue or community members to work

    the land. The limited community garden

    space at the Presidio does not satisy

    existing public demand. There is a long

    waiting list or users seeking garden plots.

    Opportunities to expand the amount

    o space or cultivation by community

    gardeners are constrained by strict

    guidelines and controls on the number o

    gardens allowed to ensure maintenance o

    an historic character. A variety o actors

    including the Presidios historic district

    designation which governs landscape

    changes contribute to the limited gardens.

    Competing land uses and the limited

    availability o non-orested level land are

    also actors.

    In spite o these constraints, the

    development o the current community

    garden in the mid 1990s is a great

    example o a way to move orward in

    spite o stakeholder confict. Eager to

    establish garden plots, the community

    gardeners became historians by digging

    out old aerials and images rom the

    historical library to identiy possible

    locations across the Presidio that had

    once been used as pleasure gardens.

    The original gardens within Fort Scott

    were identied so that they could be

    revived as gardens or the public.

    Historic preservation o the landscape

    makes increased public access and

    public gardening interests dicult to

    achieve. Some might view the lack o

    community gardens as a lost public

    benet. Histori c preservation limits

    the realization o what many view as

    an optimal land use allocation or public

    involvement. The Presidio Native Plant

    Nursery does provide some volunteer

    opportunities to actively restore sites.

    In several cases, the restoration

    approaches may circumnavigate historic

    preservation in order to both satisy

    recreational needs and achieve a

    beautiul landscape. The nurserys role

    in providing land use opportunities,

    which satisy urban residents demands

    or community gardening while meeting

    historic preservation constraints, is an

    example o programming that can enable

    additional public accessibility to the site.

    Restoration Ecology: Providing a Way

    to Align Stakeholders

    Multiple restoration projects have been

    undertaken since the U.S. Armys

    closure o the Presidio base in 1994. A

    review o these projects reveals the

    planning and design challenges posed by

    conficting and incompatible land uses,

    precedent land management decisions,

    evolving disciplinary, preservation, and

    conservation approaches.

    In 1994, The Army transerred the land

    to the National Park Service, and with its

    mission o preserving unimpaired the

    natural and cultural resources and values

    o the National Park System, the Park

    Service began a airly broad restoration

    eort (Fig. 2-8). In 1996, approximately

    80% o the Presidio was transerred

    to the Presidio Trust. Restoration can

    be viewed as a undamental tool or

    satisying both the National Park Systems

    and the Presidios mission o enhancing

    natural areas as enduring resources or

    the public. The Natural Areas Program is

    a program designed to preserve, restore,

    and enhance San Franciscos natural

    ecology and to develop community-

    based site stewardship. The purposes o

    Natural Areas stewardship are ecological,

    historical, educational, aesthetic,

    and spiritual.

    Restoration ecology at the Presidio reveals

    the challenges posed by conficting

    interests and incompatible uses. It

    raises the question: how can ecologically

    appropriate restoration be compatible with

    cultural and historic preservation interests?

    In addition, it can be dicult to change

    prevailing public perceptions o ecological

    restoration. The public oten views

    restoration as replacing a park-like setting

    with a less user-riendly environment.

    Mature trees are understandably a much-

    loved component o parks, and restoring

    areas o mature parkland to coast scrub or

    grasslands, or example, may not always

    mesh with the desires o urban residents in

    need o respite.

    The establishment o the Presidio Native

    Plant Nursery provides a way or Presidio

    Trust, community volunteer and ecological

    goals to align. The Presidio Native Plant

    Nursery supports habitat restoration,

    creates a connection between the

    park and the community, and helps

    people understand the importance o

    environmental sustainability, restoration,

    and parklands stewardship. Sta and

    volunteers grow 60,000 native plants

    annually or habitat and orest restoration

    projects throughout the Presidio, collect

    seeds, care or plants, and construct

    compost piles. There also exists in our

    society a general lack o public knowledge

    about the ecological merit o various

    landscapes. Together these historic and

    cultural actors position some stakeholders

    against ecological restoration. The Presidios

    highly urban context results in signicant

    social demands on the land: or example,

    residents want jogging trails and desirable

    views rom houses. From a dierent

    perspective, historians value the Presidio

    landscape as historical documentation o

    the past military presence.

    Still, many environmentalists are calling

    or the complete removal o the non-

    native Historic Forest planted on site and

    its replacement with what was originally

    there, including sand dunes, coastal scrub

    communities, and riparian habitats. The

    riparian habitat restoration has more

    easily garnered public acceptance, and

    indeed there are now several successul

    examples o Presidio restoration projects

    that include coastal wetlands and creek

    daylighting. The Presidio Trust also sees

    value in ecological restoration as a strategy

    restore a lands native ecosystem? Or

    is it more essential to cater to human

    needs, and allow or some environmental

    value gained through public access to

    natural areas? In the case o the Presidio,

    there are a number o examples where

    restoration ecology brought dissenting

    voices together towards a common cause.

    Establishing restoration projects on-site

    attracts a substantial volunteer contingent

    to help demolish, grade, and re-plant the

    landscape. Public acceptance o and

    participation in restoration projects can also

    generate a sense o community ownership

    and investment. While many restoratio n

    projects at the Presidio have concentrated

    on providing habitat or endangered plant

    species such as Clarkia franciscanaand

    Arabis blepharophylla, provisions have also

    been made or public use, access, and

    viewsheds. Thus, restoration has beneted

    diverse interests, including historic

    preservation, the natural environment, and

    public access.

    There are a number o concerns about

    restoration ecology as an applied science.

    How does a practitioner decide which

    historical landscape is most appropriate

    to reconstruct? The goals o restoration

    to uphold its mission o providing resources

    or public use. Extensive participation

    by volunteers in restoration projects is

    urther evidence o public acceptance o

    ecological restoration.

    Restoration at the Presidio provides an

    interesting case study o the intersection o

    planning, design, public use, ecology, and

    history. In several cases at the Presidio,

    ecological restoration circumnavigated

    historic preservation to satisy recreational

    criteria and public use. For the community

    garden and other restoration sites,

    gardeners and ecologists act as historians

    or geographers, teasing apart the history

    o the site through local knowledge, old

    photographs, maps and knowledge o

    what was once in the area. Ecologists

    mine the evolutionary past to identiy

    a prior landscape condition deemed

    appropriate or restoration. Because o

    the urban nature o the park, the resultant

    built product may be a compromise

    between an early landscape condition

    and the needs o the present.

    The battles at the Presidio reveal a larger

    issue linked to environmental restoration:

    what is the goal o a restoration project

    in an urban context? Shoul d one aim to

    such projects more dicult to und.

    Additionally, because much o the projects'

    systems are hidden, opportunities to

    educate the public about the site

    are curtailed.

    Because this approach minimizes the role

    o visible design, it discourages many

    designers rom exploring congurations

    and approaches that might have greater

    ecosystem unction. An approach to the

    built orms o restoration ecology that does

    not always deault to the naturalistic would

    promote a more dynamic relationship

    between designers and ecologists.

    maintained are naturalistic as opposed to

    geometric in orm.

    Somewhat predictably, ecologists and

    designers have divergent views on

    the orms that restoration should take.

    Generally, ecologists want to create

    something that looks like nature and does

    not stand out, whereas designers want

    to reveal the human hand. Naturalistic

    design, by denition, brings little attention

    to itsel. As a result, the public tends not

    to recognize restoration projects, and

    not to understand their place in human-

    constructed environments. This can make

    can oten be driven more by a desire

    to establish historical conditions than to

    instate a biological system that unctions

    under current conditions. What orm

    should a restoration project take?

    Ecologists typically view nature as a model

    or developing restoration projects, and yet

    the process o construction, maintenance,

    and even the locations o many o these

    projects are ar rom natural. Natural istic

    design approaches may also be more

    expensive. Many building materials are

    sold in geometric units; construction and

    maintenance can consume more time and

    money when the orms to be created and

    The Historic Forest: an Ecological and

    Cultural Conundrum

    The 300-acre Historic Forest is composed

    primarily o single-species groves

    (eucalyptus trees, Monterey cypress,

    and Monterey pine) planted in regiments

    across the landscape. Today, this planted

    orest has matured, creating a dense

    canopy that inhibits the emergence o

    understory vegetation.

    A deeper understanding o the orest and its

    history illustrates how it has been shaped

    by preceding land management decisions

    and historical preservation. New ecological

    ideas are being explored and tested to

    possibly retrot or enhance the Historic

    Forest or improved ecosystem unction.

    Major William A. Jones Plan or the

    Cultivation o Trees upon the Presidio

    Reservation (1883), one o the largest

    landscape plans o its time, called or

    thousands o eucalyptus, pine, andcypress groves to be planted in rows,

    representative o military order. The

    plantings were envisioned to accentuate

    the posts size and create a clear visual

    distinction rom the surrounding city. The

    plan, based on contemporary ecological

    understanding, called or a mixture

    original vision never ully materialized.

    Forest plantings were initiated on the

    dunes in the 1890s and mostly completed

    by 1906, but continued sporadically

    over a 55-year period, ending in the early

    1940s. The straight rows o trees planted

    in groups have created a unique orest

    o mature single-species growth with

    a high canopy and minimal understory.

    This planted orest is celebrated as a

    cultural symbol o the Presidios military

    past. The high canopy, which allows

    extended views across the shaded orest

    loor, is championed by pedestrians,

    recreationists, and dog-walkers. Even

    some environmentalists view the orest

    as a special place, a green respite within

    the city. The National Historic Landmark

    District designation granted to the Presidio

    in 1996 solidied the Historic Forest as a

    key landscape eature.

    Despite the intentions o the Army and

    Major Jones to use the orest plantation as

    an environmental management technique,

    many ecologists and environmentalists

    currently argue that the orest is a symbol

    o an invasive and manipulated Presidio

    landscape that has supplanted the native

    habitats. They note that any ecological

    value the Historic Forest might have is

    diminished by the act that only 10 percent

    o the Presidios land supports the native

    plant community that existed prior to

    landscape modications. Over time, the

    planting o non-native, limited-species tree

    stands has resulted in signicant native

    habitat and wildlie losses. Consequently,

    many ecologists and environmentalists are

    calling or portions o the Historic Forest to

    be modied and converted into a

    native landscape.

    Nonetheless, the existing orest does

    have some signicant ecological merit,

    as it supports nearly 200 bird species and

    contains a ew mixed tree species stands.

    It is also notable that a signicant portion

    o public users view this orest as a natural

    respite in the city. This perception, and the

    value that people nd within the woods as

    a natural amenity, gives the Historic Forestinherent worth regardless o its actual value

    as an ecosystem.

    A 2001 vegetation management plan called

    or changes to portions o the Forest by

    removing some mature stands in danger

    o wind-all and replacing the stands with

    native, diverse plantings (see Fig. 2-10).

    Further discussion o reorestation can

    be ound in the Restoration Ecology

    section o Chapter 3.

    EDAW - Presidio Trust

    Interdisciplinary

    Collaboration

    EDAW teamed with the Presidio

    Trust in a collaborative workshop to

    repurpose the Presidios Fort Scott Creek

    Area. The interdisciplinar y exchange

    brought together EDAW's technical

    experts with multiple stakeholders

    working with and/or within the

    Presidio Trust. As the diagram (Fig.

    2-11) illustrates, there were several

    exchanges required or successul

    collaboration. First, the EDAW team

    members needed to communicate

    internally; second, the Presidio Trust

    and EDAW team needed to work

    together; and third, this larger team

    needed to understand and respond

    to stakeholder viewpoints and concerns.

    The EDAW team built an initial

    relationship with the Presidio Trust

    through conerence calls and planning.

    Together, EDAW and the Presidio Trust

    devised the workshop schedule. This

    initial collaboration led to discussingand highlighting shared goals. The

    resultant shared goals helped build

    trust, and led to an exchange o critical

    inormation. The Presidio Trust provided

    guidance throughout the event, helping to

    orient the team and enhance the results.

    The week-long workshop was

    organized as an ongoing dialogue

    between the designers and ecologists.

    Facilitating exchange, both in planned

    discussions and through inormal

    interactions such as site walks, was a

    key goal. We created many situations

    or interdisciplinary communication,

    including evening events, lunchtime

    discussions, and hands-on activities

    to promote dialogue and to reveal the

    underlying goals and intentions o the

    individual group members.

    public use, natural areas, and historic

    In act, the meaning o space intensies

    as its layers o use increase. An urban

    park is the apotheosis o this synergy.

    The Presidio is exactly this type o space,

    combining ecological systems o plants,

    water cycles, and nutrient exchanges with

    the human ramework o walking trails,

    historic preservation, community gardens,

    playing elds, and picnic areas.

    Our hope was that collaboration between

    stakeholders could be used as a catalyst

    or integrating the public use o natural

    areas into an urbanized setting.

    The Presidio Trusts practice o planning and

    design strives to balance the competing

    interests o public use and access (P),

    natural areas/restoration needs (N), and

    historical preservation (H). (see Fig.

    2-12). The se three types o land uses are

    essential to the Presidio Trusts mission, its

    cultural identity, and its role as a public

    parkland within an urban area. Each o

    these drivers has shaped the Presidio up

    until the present day.

    Figure 2-13 illustrates the diversity o

    Intent

    Our goal or the site visit was to interpret

    the land rom an integrated ecological

    and design angle. The team intended to

    discuss and plan the visit thoroughly with

    an eort to integrate typical site analysis

    strategies that ecologists use with designer

    approaches. A brie initial slide show on

    land-use history and site conditions helped

    establish a shared baseline understanding.

    A visit to key locations across the Presidio

    allowed the team to experience the

    landscape and assess its ecological

    unctioning. We planned to document the

    site together through mapping and analysis.

    Intent

    The convening o stakeholders was

    intended as a rapid outreach approach to

    understand constraints, learn about site

    uses, and discuss potential opportunities.

    The team hoped to appreciate the

    stakeholders' multiple viewpoints and

    develop a deeper understanding o

    stakeholder needs. By the end o the

    day, we planned to generate a list o

    stakeholder goals and objectives or Fort

    Scott Creek and synthesize these goals

    into an overall approach.

    The goal o this session was to begin to

    translate goals and visions into a physical

    Fort Scott. Beorehand, we discussed

    ways o working together to develop a

    process to complete the work tasks.

    The goal o the process was to acilitate

    the development o a nal presentation

    Lessons Learned

    rom the Presidio

    The Presidio workshop yielded many

    lessons about the viability o combining

    ecology, public use, and history through

    design. The process also exposed

    the multitude o planning and design

    challenges in addressing the Historic

    Forest, community gardens, and

    ecological restoration activities. Adeeper exploration o these challenges,

    presented in the ollowing pages o

    analysis, reveals a number o themes

    infuencing planning and design at the

    Presidio. These included: conficting

    and incompatible land uses; precedent

    land management decisions; evolving

    ecological and historical disciplinary

    approaches; and various preservation and

    conservation approaches. The ollowing

    pages aim to introduce the Presidio

    site studied within the C + P Initiative,

    and to educate ecology and design

    practitioners about the challenges

    o moving toward consensus or land

    planning in an urban park.

    Outcome

    Participants learned about the larger vision

    o the Presidio and saw examples o other

    projects that had successully navigated

    politics and ound solutions through

    compromise. The tour o the Presidio

    was especially useul because questions

    came rom space ecological and designperspectives, so the team became more

    educated as a whole.

    The visit to Fort Scott Creek allowed us to

    amiliarize ourselves with the site and to

    document it through hand mapping and GIS.

    The high points were the moments when

    an ecologist and designer walked together

    and discussed ideas rom both perspectives

    about that particular area.

    While executing the site visit with a mix o

    ecologists and designers generated trust

    across disciplines, the site visit needed

    more direction, with specic activities

    to acilitate communication. An early

    concept that we explored in depth was

    to develop a physical intervention as an

    artistic gesture and scientic experiment

    (see Fig. 2-17). For example. we discussed

    ways o mapping ecology physically on the

    landscape to make it more visible.

    Objective

    Our goal was to work collaboratively,

    utilizing skills as designers and ecologists to

    analyze the Presidio and to experience and

    interpret the Fort Scott Creek project area.

    Process

    The group toured the Presidio with multipleexperts to understand existing land use

    patterns and to see rsthand how the

    Presidio Trust has been i mplementing

    its missions o land stewardship. Michael

    Boland and Allison Stone o the Presidio

    Trust led the tour, which included a number

    o destinations exhibiting site restoration or

    native habitats. These included Inspiration

    Point; the Mountain Lake restoration;

    multiple neighborhoods; coastal blus;

    a plant nursery; historic and community

    gardens; Fort Scott; and the Creek. Other

    participants included Betty Young, Mark Frey,

    Laura Castellini, Damien Raa, Barb Co;

    Johna Maeck, and Jean Koch.

    Ater a long debate, we voted to rely on our

    individual expertise and typical practices as

    designers and ecologists. This diered rom

    our original idea to pair an ecologist with a

    designer in the eld and encourage dialogue

    on-site. The idea was that using the methods

    we would employ on any other project would

    give the client the best results.

    Objective

    The goal o the stakeholder meetings

    was to learn about the various visions

    or the Fort Scott area and creek. This

    was achieved through a process o public

    engagement that ocused on stewardship

    and sustainability. The team interacted

    with the volunteer groups, historicpreservationists, restoration ecologists,

    the maintenance and operations group,

    and the architects working on the

    sustainability building or the cen ter.

    Process

    The EDAW/Presidio Trust team worked

    together to establish a clear workshop

    schedule (Fig. 2-14).

    The Presidio Trust organized stakeholder

    groups or the EDAW team to intervi ew.

    Each group met independently with

    the EDAW team, allowing the team to

    eciently and concisely understand

    the concerns and desires expressed byeach group (Fig. 2-14). Key players rom

    each stakeholder group were invited to

    participate in a wrap-up strategy session

    to develop goals and objectives.

    Outcome

    The stakeholder meetings were a

    ormative part o the workshop. The

    perspectives shared during the meetings

    exposed the dynamic, complex, and

    pluralistic nature o the Presidio. The all-

    day dialogue proved to be a tremendous

    success or both the EDAW team and thePresidio. The EDAW Team built trust with

    stakeholder groups through the dialogue

    process, and claried a working set o

    goals and objectives.

    In part, this exercise was valuable or

    the stakeholder groups and Presidio

    Trust because the workshop brought

    some stakeholders together or the

    rst time. This event gave them an

    opportunity to learn more about each

    other, to recognize opposing positions,

    and to conceive o ways to move

    orward in alignment.

    The multidisciplinary discussion steeredthe energy o all participants toward a

    common vision. The goals articulated and

    agreed to by the stakeholder groups built

    on the Presidio Trusts mission: to balance

    historic preservation with sustained

    ecological systems while ostering public

    engagement. It is this attempt to satisy

    contradictory perspectives enriched the

    dialogues by revealing the site's core

    planning challenges.

    The pre-workshop planning served us well

    in ensuring that every stakeholder voice

    was represented within the design team.It proved important to have someone
