SummaryThe following report summarizes a Peer Workshop on tools and effective practices for scenario planning. The Federal Highway Administration (FHWA) coordinated and led the daylong workshop in Burlington, Vermont. Presenters from the FHWA provided participants with an overview of the scenario planning process and described available resources and tools to assist with scenario planning analysis. Local planning staffs, elected officials, and consultants joined the Chittenden County Metropolitan Planning Organization (CCMPO) for a one-day scenario planning workshop. Attendees hailed from across the region and shared their views on introducing scenario planning to their planning processes. Presenters from the Binghamton Metropolitan Transportation Study, the San Luis Obispo Council of Governments, Renaissance Planning Group, VTrans, CCMPO, and the Federal Highway Administration provided the group with information on implementing scenario planning in a variety of community contexts. I. WelcomeA. Karen Glitman, University of Vermont University Transportation CenterMs. Glitman welcomed the group and gave a brief overview of the University Transportation Center. The University of Vermont, which was the location of the meeting, was designated as a National University Transportation Center in August of 2005 and has been actively involved in transportation education and research. B. Peter Keating, CCMPOMr. Keating thanked local officials for attending and noted that the CCMPO is considering using scenario planning in the upcoming update of their metropolitan transportation plan. An objective of the workshop is for the CCMPO Board to learn about using scenario planning so they can consider it as a tool for the plan update. A common theme of the scenario planning experiences presented today is the use of extensive and intensive public participation. Following the meeting, CCMPO staff will review findings and determine how to move forward. II. IntroductionA. Overview of Scenario PlanningJody McCullough, Community Planner, Federal Highway Administration Office of Planning Ms. McCullough provided the group with an overview of scenario planning and how it could be used for a more effective transportation planning process. FHWA has been working to promote scenario planning for several years as a tool for integrating transportation with other activities in the community. It has been shown to be a method for creating a positive visioning and public participation process. Scenario planning is not about trying to predict the future, but rather about understanding what you want, using new technologies to understand the impacts of project decisions, and ultimately making better-informed decisions. FHWA defines scenario planning as "a process in which transportation professionals and citizens work together to analyze and shape the long-term future of their communities. Using a variety of tools and techniques, participants assess trends in key factors such as transportation, land use, demographics, health, etc. Participants bring the factors together in alternative future scenarios, each of these reflecting different trend assumptions and tradeoff preferences. Around the country, scenario planning processes take place under different names, such as Blueprint (California), Envision Utah, and others. Although the processes vary, they have common themes. Scenario planning allows the community to develop "what-ifs", which can be conservative or more creative, to understand some plausible futures and spark discussion. It is useful for getting people to the table early in the process. People are often more wiling to make tradeoffs if they understand why the decisions have been made. Queensland, Australia was an early proponent of scenario planning for transportation and land use. The 4seeable Futures Project laid out the following process:
Benefits of Scenario Planning:
Visualization tools are helpful, as people interpret data in different ways. Scenario planning can take advantage of new technologies, but some areas have used markers, maps, post-it notes, and photos to benefit from a "low-tech" and affordable process. FHWA's role in scenario planning is to encourage agencies to investigate it and experience the community-building benefits of using a scenario planning process. The FHWA Scenario Planning website provides information on tools, technologies, and case studies from across the country. Over the next year, FHWA will be doing follow-up to understand some of the long-term benefits that communities may experience. Discussion Is scenario planning always led by the transportation agency? Can using scenario planning really lead to different projects? Most of the cases seem to be drawn from big cities. Would scenario planning be useful at a small community level? Scenario planning is an adaptable process and has been used successfully in smaller towns, such as Mooresville, North Carolina and St. George, Utah. Some software tools, such as CommunityVIZ, go down to the parcel level and are often used in small towns. In Mooresville, construction of the headquarters of a major company was expected to suddenly bring 10,000 new jobs to the community. Using scenario planning, the community developed strategies for quick implementation.III. Peer PresentationsA. Presentation: Scenario Planning: Writing Your Community's Story Ms. Twaddell introduced scenario planning and some typical techniques, drawing upon case studies in Charlottesville, Virginia; McLennan County, Texas; and Warren County, New Jersey.
To answer the questions, "where are we now?" and "where are we going?" the lead agency will need to develop data, such as the following. Preferably, all of these factors will be included in GIS format at some scale, but the dataset will vary by community.
Four key characteristics of the built environment are particularly important to collect and categorize for urban, suburban and rural areas. Research has shown that these elements, dubbed "the Four D's," have the strongest influence on travel patterns, including vehicle miles traveled, number of trips, and mode choice. They include:
To gather data on the local community from the public, workshop and meeting participants may be asked to generate or validate commonly held values and to map their "treasured places," as a way of understanding how core values are reflected in local development patterns. These discussions naturally lead into identifying development patterns and specific design elements that people do not like. Through this process, community members can clarify what they mean by often-controversial terms such as "sprawl," "density," "economic development," and "environmental preservation," and they can achieve consensus on a few fundamental principles that will guide the entire scenario planning process, from choosing key issues to developing scenario evaluation criteria.
Until the group can agree on overall core values and goals, it is helpful to keep the discussion on the big picture. Often the conversation can be built upon previous initiatives, and does not have to start from scratch. In Charlottesville, for example, the regional sustainability council created an extensive list of values, goals and indicators that were validated and focused at the onset of the scenario planning process. Often, the lists of goals are very similar from community to community, but it is critical to conduct broad input and face-to-face conversations in order to create them, both to gain immediate "buy-in" and clear direction for the study, as well as to encourage commitment to implementation at the end of the process. During the next stage of the process, the lead agency addresses the questions of "where are we going? and "where do we want to be?" by generating information such as the following:
A trend scenario based on existing development patterns. Figure 3: Existing and "enhanced" suburban community element, Jefferson Area Eastern Planning Initiative After validating people's common understanding of these values and how they are currently reflected in existing and potential future urban, suburban, and rural settings, workshop participants can use dots or chips on maps to construct alternative future growth scenarios that seek to address their values. For example, workshop participants in the case study communities generated potential future land use and transportation patterns that sought to achieve values-based themes such as "transportation choices for everyone," "creating vital core cities," or "preserving our natural landscape." Based on the ideas generated by the community, the lead agency can then build alternative future development scenarios and test their impacts using software tools that support scenario planning and visualization. It is important to assess impacts that relate to all the core values and goals people put forth, even though some can be challenging to quantify in a model. This is why it is helpful to make the effort early in the process to clarify values and goals in specific, definable ways focused on physical characteristics of the landscape such as "the Four D's."(click image to enlarge) Figure 4: Values and Indicators, McClennan County Future Land Use Study The scenarios should differ from one another as much as possible, so that the community can see and discuss the difficult trade-offs that may be involved in agreeing up on a vision. In Binghamton, for example, the process helped participants understand that there was not enough projected growth to revitalize the urban core while also continuing to support new suburban development. The trend scenario showed that development was clearly migrating out of the core cities to the suburbs, and that a concerted effort would have to be made to re-direct it as well as stimulating new urban growth. The travel demand impacts of the preferred development scenarios were modeled to show changes in transportation performance and levels of investment compared to the results under the current plan. The resulting vision and transportation plan made a clear policy statement that urban transportation investments were a higher priority than suburban highway expansion, even if this meant tolerating some congestion in the suburbs. Understanding the impacts and associated costs of transportation investments for each scenario helps the community to understand the most feasible and appropriate strategies to consider. The process helps people think all the way through the impacts of their vision and decide where they are willing to compromise in order to move forward more effectively. In Charlottesville, for example, scenario planning helped people understand that there simply was not enough density to support rail transit, which had long been argued for by rail advocates. Many now support the development of Bus Rapid Transit, which is a more sustainable and affordable form of transit for the city's size and scale. As community members participate in evaluating the scenarios, the focus is on the final two questions of the scenario planning process: "where do we want to be?" and "how will we get there?" Workshop participants discuss and tweak the scenarios in order to craft a single "preferred" scenario upon which a vision can be constructed. It is important at this point to ensure the community understands the difference between a vision and a plan. The vision provides a clear picture of the community's desired future, both in words such as guiding principles and in pictures such as a map of the preferred scenario and graphics that show desired development patterns for urban, suburban and rural settings. It provides clear direction on what should happen, but it does not dictate how the job should be done. The process of deciding how to go about achieving the vision is done after the scenario planning process is complete, by updating local, regional, and state plans, policies and programs relevant to land use, transportation, economic development, environmental preservation, and other key elements that affect development patterns. Scenario planning tools can be used for any and all of these followup planning activities, and are particularly useful in testing alternative strategies for consistency with the vision. Many other planning and policy tools can be developed based on the ideas and information generated through the visioning process, such as --
Discussion Moving quickly can build momentum among a core group of dedicated people, but may require simplifying the analysis and reducing the breadth of public engagement. Longer processes allow for richer technical analysis and more extensive outreach. In any case, it is important not to let too much time go by without some form of community outreach such as workshops, committee meetings, focus groups, interviews, and media updates (two to four weeks for shorter processes, one to three months for longer ones). How do local and regional visions work together successfully? Both are important and there are areas of overlap. At a local level, the visioning process can and should consider the context of regional development patterns and travel demand on the desired future, since local outcomes and issues are highly influenced by - and influence - these outside factors. At the regional level, the scenario planning process provides a useful way build a vision based on a regional pattern that reflects "the four D's" of desired land use and transportation conditions at a site-specific, local level. It also provides an opportunity for communities whose plans and visions may be in conflict to craft a shared future in which they all can "win."B. Presentation: Transportation Tomorrow 2030: Placemaking for ProsperitySteven Gayle, Binghamton Metropolitan Transportation Study (BMTS), Binghamton, NY BMTS serves as the metropolitan planning organization (MPO) for the Binghamton, New York region. The Binghamton area has been experiencing a slow economic decline and population loss along with a "hollowing of the core": a declining downtown and only slow suburban growth. In 2004, BMTS hosted a scenario planning workshop, which kicked off a scenario planning and visioning process for the Binghamton area. The subsequent plan, Placemaking for Prosperity, grew out of the process and was well-received, earning awards from the Association of Metropolitan Planning Organizations and the United States Department of Transportation. Before the BMTS study, scenario planning had mostly been used in high-growth areas. Introducing scenario planning to Binghamton allowed participants to consider the question, "what is success if it is not growth?" It also allowed BMTS to talk about core livability issues, not just technical topics, such as levels of service or hours of delay. Participants were able to agree on a preferred scenario. That scenario, "Moving In", was summarized as "revitalize and redevelop the urban core communities. A region with a hollow core cannot ultimately be successful." The public outreach and visioning portion of the process was completed relatively quickly, within six months, in order to meet Federal deadlines. Implementing the preferred scenario is not entirely within the control of BMTS and participants were made aware of this. However, the transportation plan was written to reflect the outcome of the scenario planning process. While BMTS does not have the power to shift development away from the suburbs, it can focus transportation projects in the areas where development is desired. The Transportation Improvement Program (TIP) is soon due to be updated and will serve as a test of the communities' commitment to the preferred scenario. Some impacts can already be felt. For example, the scenario planning process led to a new focus on the needs of elderly pedestrians in the urban core, and signal timing decisions have been made to reflect those needs. Also, some progress has made towards integrating the university and the county transit systems. In conclusion, Mr. Gayle noted that a challenge of scenario planning can be reminding the participants that the vision is for a 25-year process and cannot be implemented immediately. Discussion Is BMTS working with the university? Was there direct involvement by the disabled community in the process? How were economic development agencies involved? What was the cost of the project? C. Presentation: Community 2050 UpdateSteve Devencenzi, San Luis Obispo Council of Governments , San Luis Obispo, California Overview The San Luis Obispo Council of Governments serves San Luis Obispo County in central California. California's transportation agency, Caltrans, has been promoting a form of scenario planning known there as Blueprint. Many agencies across California have participated in Blueprint projects, which have generally been lead by MPOs. Caltrans also sponsors the Blueprint Learning Network to advance the Blueprint process statewide. Members meet three times each year to share information and experiences. SLOCOG received a Blueprint grant from the state in fiscal year 2005-06 to undertake a scenario planning process. This process, called the Community 2050 Update, centered on having the community envision the region's future. SLOCOG started with its municipalities' 20-year plans, and then asked how people wanted the region to develop from there over the next couple of decades. SLOCOG endeavors to align each agency in the region with a shared, public vision through the scenario planning process. To succeed in this process, SLOCOG divided the county into four parts based on each part's own distinct markets (for example, jobs and housing) and characteristics; this allowed smaller areas within the county to be heard. The four parts were the North Coast, Central Area, North County, and South County. SLOCOG set up stakeholder involvement committees with locally elected officials and other interested parties in each of the four parts of the county to solicit their input and to get their buy-in early on. SLOCOG ensures that they have locally elected officials on board as early as possible to engender a feeling of ownership of the process. They also stress that a regional vision is being created that the communities can choose to implement in their plans, or not. SLOCOG held a series of workshops in each of the areas in the county as part of their 2050 visioning process. The general public was invited, and elected officials and planning commissioners also attended. At the workshops, members of the community and stakeholders got together to review existing maps and brainstorm ideas for new development. The main purpose of the workshops was to build awareness and consensus. SLOCOG created "Development Type" menus in their model, described more below, that enabled participants to create alternative scenarios (Development Type indicators are listed in Box 1). The scenarios are compared on the fly to assist in developing new ideas. Interactive polling was used to ask participants what summary concepts and scenarios they most preferred. Existing land use served as a baseline scenario to compare proposed land use changes and to evaluate development impacts.
In working with stakeholders and the public, SLOCOG found real-time analysis of the scenarios to be an important tool in demonstrating how infrastructure decisions shape the community. Having real-time results also helped SLOCOG build trust and bolster public buy-in, as the process was open and transparent to the participants. At the public workshops, participants were first seated at tables within a meeting room, then given chips to place on a map of the county in areas where they thought population and jobs should be located between the years 2030-2050. Participants were given the choice of several chip sets, from low-density (business as usual) growth up to high-density growth. As participants sketched out future land use scenarios, forecasters at each table entered information into a computer. Through a program called iPLACES, which was connected to the region's traffic model, the computer yielded immediate feedback to emphasize the relationship between land use choices and traffic conditions. Figure 4 shows how SLOCOG used technology to inform workshop participants of the transportation impacts of their development choices. Generating feedback took only 15 minutes. When people saw the impact of continuing low-density growth on their community and the surrounding environment, many participants traded their lower-density chips in for higher density chip sets, and new information was entered into iPLACES. Technical assistance for the project was provided by nearby California Polytechnic University. Working with the local university enables SLOCOG and local units of government to take advantage of a broad knowledge base and a pool of student labor. California Polytechnic University houses GIS data and makes it available for use by all. A master agreement governs the university's work with SLOCOG and acts as a simple mechanism to facilitate a wide range of technical assistance.
The program SLOCOG used to translate the participants choices into regional impacts - iPLACES - is a parcel-level web-based scenario planning tool that is the successor of PLACE3S. PLACE3S is a desktop scenario planning tool that has been used by the Sacramento, San Francisco, and San Diego regions. SLOCOG is now using UPlan, a tool developed by the University of California at Davis in partnership with CalTrans. UPlan models where land use changes will occur in response to the transportation infrastructure. Lessons Learned Challenges SLOCOG faced include performing complex tasks quickly in front of a large audience. Doing this is necessary for real-time results, but is inherently risky. SLOCOG found that it was a good idea to have backups ready for everything. Another lesson learned was that when the public uses the same tools that planners use, they understand planning much better. Participants learned a lot from the results of their first scenario. Giving them time to develop a second scenario reinforces the lessons they learned. SLOCOG found that it was important to agree on goals, to develop principles of agreement, and to measure development based on these principles throughout the process. Next Steps Other next steps include doing a smart growth inventory of local communities' existing regulations and ordinances. The work will be performed by the California Polytechnic University, as part of its ongoing relationship with SLOCOG. Discussion Can scenario planning be used to address climate change? Yes. Although the transportation models are not sensitive enough to address walkability, different scenarios resulted in higher or lower estimates of emissions. D. Presentation: Scenario Planning ToolsBrian Betlyon, Metropolitan Planning Specialist, FHWA Resource Center; Baltimore, MD Brian Betlyon discussed the role of tools and techniques in scenario planning and provided information on additional resources. According to Betlyon, the premise of scenario planning is that it is better to "get the future imprecisely right" than to "get the future precisely wrong" when developing transportation plans. Tools can help people involved in scenario planning get the future as "imprecisely right" as possible. These scenario planning tools can provide decision-makers and the public with the information they need to make educated decisions. Scenario planning tools can help communities plan by design instead of by default, meaning that they can make informed decisions on how the actions (or inaction) that they take today will affect the future. A variety of technology tools can help communities consider scenarios and make better decisions. These tools can be divided into the following categories:
IV. Local PerspectiveA.Secretary Neale Lunderville, VTrans; Mel Adams, Director of Policy and Planning, VTransVTrans has entered into a scenario planning process at the state level to update the long-range transportation business plan. Four scenarios were developed by a consultant team based on the results of phone interviews with 1,200 residents, data review and findings, interviews with national and local experts and twelve focus groups:
B: Presentation: Scott Johnstone, CCMPO Executive DirectorMr. Johnstone noted that CCMPO is fortunate in having in-house modeling and GIS capabilities. Scenario planning is one way to use these tools productively. For the plan update, Mr. Johnstone suggested using a 50-year time horizon with a "check-in" at the 20-year point. Land use cannot be reshaped within 20 years, due to building life spans. Consequently, using a 20-year process alone will reinforce the status quo, as the only thing that amortizes over 20 years is pavement. If, instead, the process uses a long enough view, sustainable choices will always win. Using scenario planning will allow the community to consider different futures, including those that may be uncomfortable. Possible futures might include becoming an air quality non-attainment area, peak oil, climate change, population change, and Federal funding changes. The process to use could develop several scenarios, a bandwidth approach, or "best guess" hybrid approach - integrated resource planning (IRP). V. DiscussionA: Breakout Session 1: Pair DiscussionsWorking in teams of two, participants took turns completing the sentence, "in 50 years, the CCMPO region will be a place where _________..." Responses ranged from "West Palm Beach, due to global warming" to "where people feel safe". Common themes were the desire to increase affordable housing; dense, mixed-use development; the availability of transit; and sustainability of local industry, local agriculture, and development. B: Breakout Session 2: Small Group DiscussionsParticipants met in small groups to discuss the questions, "where are we now, where are we going, where do we want to be, and how will we get there?" Following the discussions, each group reported out. C: Peer PanelTo conclude the workshop, each of the peers answered questions from the group and provided final thoughts.
