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 Moorhead, Minnesota. 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 MetroCOG 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 Chittenden County Metropolitan Planning Organization, Community Planning Association of Southwest Idaho (COMPASS), and the Federal Highway Administration provided the group with information on implementing scenario planning in a variety of community contexts.I. WelcomeMr. Williams welcomed the group and thanked KYTC and FHWA staff for putting together the program. He noted that it is important to implement these types of planning capability and technologies to evaluate options and educate citizens and policy makers on the transportation system scenarios. Bob Bright, executive director of the Fargo Moorhead Metropolitan Council of Governments (MetroCOG), welcomed the group. Participants were asked to introduce themselves and state what they expected to learn during the day's workshop. Responses ranged from "branching out and thinking about ‘what if' to learning "how to plan when money's tight". Mr. Bright noted that MetroCOG is about to enter long-term transportation planning process for the metro area and scenario planning might be a worthwhile process to use. He expects it to be a community-driven process. One scenario to examine might be what would happen if the highway trust fund, which provides 80% of transportation funding in the region, were to disappear. It is currently expected be depleted in 2009 at present expenditure levels. If Congress does not take action, what would be the consequences for the Fargo Moorhead area? MetroCOG's role is to tie transportation elements together through the transportation plan. In the Fargo Moorhead area, the goal is to get to level of service (LOS) C. MetroCOG coordinates with local jurisdictions to program Federal funding for transportation projects. Locally, growth has been healthy over last six years, growing by approximately 2% each annually. Growth is not dispersed throughout the metro area, but rather is concentrated in particular areas. Some intersections have seen traffic volumes double over the period from 2000 to 2006. Population forecasts suggest population growth of approximately 30% between 2005 and 2025. Construction costs have recently risen by approximately 25% and are expected to do so again by 2010. As project costs increase, however, revenues are not increasing at the same rate. How can the region adapt and plan for radically decreased levels of Federal funding? Will congestion occur? Will the pace of growth be impacted?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 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." Scenario planning is not a prediction, but a visioning process that can identify best and worst case scenarios and develop alternatives so that a community is not blindsided by change. Existing conditions, trends, and driving forces are used to create the scenarios. These might include not only demographic or transportation trends, but also the environment, treasured places, or livability. When trying to identify values, goals, and measures, participants are asked questions like, "What do you want your community to look like in 20 years? What are your favorite places? What do you want to create?" Communities use creativity in developing the scenarios, not all of which have to be reasonable. Ultimately, extreme scenarios may not be chosen but initially they are useful for moving the discussion forward. After picking reasonable scenarios, communities come up with goals and policies to implement them. Scenario planning does not change the planning process, but enhances it. In the past, planners assumed a particular future and developed plans and project in response to it. Now, instead of selecting a single future, planners can use new tools and technologies to understand multiple possible futures. Products of the process include reports, policies, plans, templates, design standards, and more. Queensland, Australia, an early proponent of scenario planning for transportation and land use, laid out the following process:
Benefits of Scenario Planning:
The process becomes more transparent to the public by including them in it. The public may not make the final decision, but they better understand the tradeoffs and why certain decisions are made . Having the public use planning tools helps them understand planning concepts and how decisions are made. Communities are finding that scenario planning enables a healthy public involvement process, where members of the public feel that their voices are being heard and understand that their input into the transportation planning process is important. Planning tools allow planners to analyze complex data effectively, looking at natural resources, land cover, and many other types of existing condition information. When planners include the community, they can better clarify the preexisting conceptions of the community before the decision-making occurs. Having a map and pictures of typical development types helps everyone to understand what is being discussed and helps to alleviate the use of technical jargon. The community can provide real-time input and see real-time results. As a result, participation has become much broader than in the past. Workshops can be high-tech or low-tech, using on-the-fly modeling or stickers and maps to explore the impacts of each scenario. The internet is a great way to reach out to those who do not usually attend public meetings. Visualization is a new requirement in SAFETEA-LU and the tools and technologies to implement are widely available today. Scenario planning is often used in high-growth communities experiencing new development pressures, but is also helpful in communities that are growing slowly or even losing population. Binghamton, NY is a no-growth area that is losing industries and has an aging population Community resources include a university and good quality of life. Scenario planning was used to as a tool to sustain quality of life, identify new directions, and determine how to allocate resources most efficiently instead of continuing along the current path. The Federal role in scenario planning is to build capacity and provide technical assistance. The FHWA Scenario Planning website provides information on tools, technologies, and case studies from across the country. There is no additional funding for implementing scenario planning, as it is a tool to enhance the existing process. While scenario planning requires additional up-front resources, it can reduce the chance of running into unforeseen obstacles further down the road.III. Peer PresentationsA. Presentation: CCMPO 2025 Metropolitan Transportation Plan (MTP)Peter Keating, Chittenden County Metropolitan Planning Organization Mr. Keating introduced the group to Chittenden County and to the process CCMPO used to develop their 2025 Metropolitan Transportation Plan (MTP). Vermont is a small state in area with the same population as North Dakota (600,000 people). There are 18 municipalities in the MPO region, each with land use decision-making authority. The City of Burlington itself is home to about one-third of the county population, about 40,000 people. In Chittenden County, there are concerns about maintenance of arterials, public transportation adequacy, and pedestrian and bicycle infrastructure. Land use decisions are all made at the local government level and there is only now beginning to be awareness of the need for regionalism in land use planning. Process A consultant was hired and conducted visioning workshops. The consultant assessed existing transportation conditions in the region and developed five emphasis areas: arterial roadways; public transportation; pedestrian and bike accommodation; land use and transportation; and regionalism. The public involvement was extensive. The project steering committee included approximately 20 members, representing local governments, environmental groups, pedestrian and bicycle groups, and others. There were also many meetings with the local governments. Seven transportation scenarios, including the trend and committed projects scenarios, and two land use scenarios were developed. Each transportation scenario focused on a specific type of improvement and was considered exclusively of the others. For example, the TSM /TDM projects include things like signal optimization, ITS, minor intersection improvements, ridesharing, park and ride, etc. The land use trend scenario assumes that the trend of the last 30 years continues. The concentrated development scenario assumed development concentrated in areas zoned for higher densities in existing zoning. Each transportation scenario was evaluated under the two land use scenarios. While the transportation demand model is critical to the process, other data needs include existing household, employment and transportation system information; growth forecasts; and land use scenarios. Performance measures are key to alternatives analysis. The demand model includes many different measures. CCMPO also wrote a paper correlating the measures to goals adopted earlier in the process. Performance measure categories included multi-modal support, system efficiency, costs, highway performance, air quality, and safety. Each category included multiple performance measures.
Figure 1: Estimated Vehicle Miles Traveled Under Two Land Use and Five Transportation Scenarios. The key finding was that the concentrated land use development patterns consistently produced benefits under every transportation scenario, as seen in Figure 1. Subsequently, they went through an iterative process to develop first five hybrid scenarios and then two refined alternatives. From the refined alternatives, a preferred alternative was selected. The preferred alternative was the basis for the 2025 long-range plan. The plan is gradually being implemented through the Transportation Improvement Program (TIP). CCMPO has started working on the next long-range plan. The planning process will include more traditional scenario planning techniques and examine a broader range of issues. The State of Vermont is also using scenario planning in producing its next update of the long-range statewide transportation plan. Lessons Learned
Discussion Q: What was the total cost of plan? Q: Did you use scenario planning to create a "plan in waiting" if future trends should be different than the adopted plan assumes? Q: How much reliance is there on pedestrian and bicycle transportation in your region? Q: Did the scope of work change over the five years of the project? Q: What is the transit frequency in Burlington? Q: Were all of the performance measures based on the model? Q: If we already know that density is the solution, did you show public benefits and tradeoffs to implement it? Q: Did you treat freight separately? Q: How did you engage local technical staff and politicians? Were you able to maintain buy-in over the five years? B. Presentation: CCMPO 2025 Metropolitan Transportation Plan (MTP)Charles Trainor, Community Planning Association of Southwest Idaho (COMPASS) COMPASS represents two counties, Ada and Canyon, but received Idaho Transportation Department funding to expand the scenario planning process to a 6-county region. Geographic features define the region, which is bordered by mountains, a river canyon, and a desert. Water supply also constrains development. It is a diverse region with cities ranging in size from less than 100 residents to more than 200,000. There has been fairly rapid growth since approximately 1990 and the cities are expanding into the fertile and the irrigated agricultural land at a rapid pace. Boise is the major employment center. A rail spur line connects the three largest cities and is an asset that the MPO is trying to plan for. Additionally, within Ada County, the highway district owns, maintains, and has responsibility for all the public roads outside of the state highway system. Historically, COMPASS has planned for only one future. That has not worked satisfactorily. COMPASS wanted to use scenario planning for several reasons: to tie transportation decisions to broader policies; to improve consideration of alternative modes; to reduce subjectivity in project funding priorities; to increase understanding of issues and tradeoffs; to create a vision of how to address rapid growth; and, to develop better connectivity between land use and transportation decisions. A scenario is a plausible future, not a prediction. It is a method to evaluate strategies. Process
Figure 2: Chips representing different densities for use in the mapping game. In February of 2005, a second set of workshops, focusing on transportation improvements, was held. This time, participants were given transportation "strip" types, which represented 3 miles of different roadway or transit improvements with a dollar value assigned. Of the eight land use scenarios created from the November 2004 workshops, four were continued for use in the transportation workshops: trend, workshop average, concentrated mixed-use corridors, and satellite cities. Participants picked a map representing a specific land use scenario, determined the destinations to connect, then placed their strips and discussed the placements prior to finally affixing the strips. They could trade their strips for different types. Groups could also create new funding strategies to add additional improvements. Including the cost information shaped participants' choices. For example, bus rapid transit got a lot of support when participants understood the costs vis-à-vis rail and support for adding new freeways dropped when participants realized that this could financially eliminate other types of projects. There was also considerable participation in February, with 450 participants. Lessons Learned
Outcomes Discussion Q: The cities in our region are competing with each other for growth. Did you see that in the Boise region? Q: How did you get buy-in from local jurisdictions? Q: How will you implement the plan? Q: Why did you go with the lower growth rate than that indicated by short and long term trends? Q: When dealing with the public, translating system performance is very difficult. Perception may be very different from reality. Q: How is scenario planning distinct from the standard transportation planning process? A: There is a companion project called Blueprint for Good Growth that was to do that, but that process has been more difficult. There is a perception that "sprawl is something that somebody else is doing". IV. ImplementationA. Presentation: Scenario Planning ToolsJim Thorne, Metropolitan Planning Specialist, FHWA Resource Center Mr. Thorne presented a range of scenario planning tools and resources. He recommended that participants begin by figuring out what they are trying to accomplish and then select the tools best suited to get the job done. Scenario Planning tools are a means to an end, which is to say that they exist to accomplish some other activity and are not the answer in and of themselves. There have been innovations over the years that have enhanced the planning tools that are available, but lower technology, simpler methods also have their place in this process. Land Use Models in U.S. Practice
Basic steps in the scenario planning process were reviewed and tools that could help in each step were identified. For example, tools to engage the community could include public meetings, participation in other community events, group facilitation skills, visualization, the chip game, web sites, Geographic Information Systems and other software such as Corplan or CommunityViz. FHWA does not recommend one software package over another; the choice of software will depend on the user's resources and goals. Many websites have resources to help identify the appropriate tools for various planning activities. The Public Participation Spectrum developed by the International Association of Public Participation was cited as an example of a tool that could be used to identify approaches. Scenario Planning tools are used to engage the community. Scenarios can be developed by using a wide range of tools; including traffic forecast models, chip games, GIS, or one of the specialized software packages. Resources include census data, historical records, geographic information systems and the public itself. Information and examples were provided in the following categories:

B. Breakout Session ResultsDuring the first breakout session, participants discussed what they had heard from the presenters and developed questions and discussion topics for consideration later in the workshop. All groups raised implementation as a critical issue for undertaking scenario planning in the region. Discussion topics
C: Peer PanelParticipants were given the opportunity to ask the peers and Federal Highway staff questions about scenario planning. Questions focused on process and implementation. Process
Implementation
D: Local PerspectiveBrian Gibson, Fargo Moorhead Metropolitan Council of Governments (MetroCOG) Mr. Gibson presented MetroCOG's understanding of what scenario planning is and what the process might be like for the Fargo - Moorhead area. The last metropolitan transportation plan (MTP) was approved in October 2004 and the next plan will be due in October 2009. MetroCOG is now beginning the process of updating the plan by building the new transportation demand model. Scenario planning fits into the MTP process because it will allow the Council of Governments to think through land use, funding, and demographic changes and what they mean for transportation. Scenario planning arose from the military and the private sector. Scenarios hinge forces that are often beyond our control. A famous example was Shell Oil's use of scenario planning in the early 1970s, which enabled them to weather the oil shocks and come out doing well. Scenario building process:
E: Breakout discussion groupsParticipants returned to their breakout groups to discuss three questions posed by Mr. Gibson:
Each group then reported out on primary topics of discussion. While all groups agreed that scenario planning should be pursued in the region, concerns about implementation and not repeating or losing earlier planning work were voiced. Comments
