COLLEGE PARK, Md.—The University of Maryland’s National Center for Smart Growth (NCSG) has released a report that outlines four possible future scenarios for the Baltimore-Washington region and how they might impact quality of life across the state. The landmark, five-year project,Prospects for Regional Sustainability Tomorrow(PRESTO), reveals how regional responses to large-scale, uncertain phenomena—such as autonomous vehicles, high fuel prices and government regulation—could impact economic, social and environmental health. On April 18th the report will be reviewed by Maryland Governor Larry Hogan and regional stakeholders at the Smart Growth @ 20 workshop in Annapolis.
“PRESTO is part of a long-standing effort at the National Center for Smart Growth to promote smarter and more sustainable development using science and advanced computer models at the mega regional scale,” said Dr. Gerrit-Jan Knaap, Director of the NCSG. “This allows us to go beyond micro scale issues such as walkable neighborhoods, transit-oriented development and opportunistic land preservation to larger scale systemic issues such as transportation technology, energy prices and regional development patterns. What’s more, it is clear that there is no organization that is addressing these issues in the Baltimore-Washington area at this critical scale.”
Using a highly sophisticated, interconnected modeling suite, PRESTO is one of only a handful of global efforts to simulate future conditions by playing out how “driving forces” could potentially shape an area. Focusing on land use change, mobility, equity and environment, PRESTO presents a baseline scenario which projects a continuation of current growth management and four alternative futures that the Baltimore-Washington region may face in 2040: high-level automation (nicknamed “Revenge of the Nerds”), high-tech sustainability (“Blue Planet”), deregulation (“Free for All”) and scarcity (“Last Call at the Oasis”).
The future scenarios offer radically different outcomes for the region:
- TheRevenge of the Nerdsscenario envisions a region dominated by low fuel prices and new technology, as well as relaxed government regulation. The popular adoption of autonomous vehicles increases highway capacity and dramatically reduces congestion compared to the baseline. Increased mobility and relaxed regulation on development creates an exodus from city suburbs into more rural areas.
- Last Call at the Oasisshows a very different future, where high gas prices spur investments in transit and strict land use controls, concentrating both households and jobs in the inner suburbs and creating lower levels of pollution.
- Hands-off government sets the tone inFree for All. Low government regulation, coupled with lower fuel prices, results in development encroaching into farms and forests; this scenario sees an increase in housing affordability, but also air pollution and nutrient loads.
- Blue Planetprovides the most sustainable scenario, where high fuel prices, in turn, fuel investments in transit and renewable energy, spurring local governments to increase housing capacity in the inner suburbs.
While each scenario presents different outcomes, several common themes emerged. According to PRESTO researchers opening housing capacity and increasing affordability in the inner suburbs will have positive impacts on several sustainability indicators. In addition, the inevitability of emerging technologies requires a robust, well-represented group—including urban planners—at the development table to ensure that innovations, capacity and infrastructure are properly aligned. However, both road and transit investments must be made carefully and strategically. Transit investments outside the beltways, for instance, would be less impactful than within the core. Environmental impacts such as air pollution and land preservation look to be very complex balances and will require sound, thoughtful policy.
“Because we tested some extreme infrastructure and land use options, we have gained new insights into their intended and unintended consequences,” said Uri Avin, research professor at NCSG. “These are the building blocks for future strategies that are robust enough to cope with a changing world.”
While the idea of PRESTO is not to predict which future will come true, researchers hope it will help guide policymakers in how they prepare. The approach taken by the researchers stresses the importance of accounting for the uncertain conditions that policymakers may encounter along the way. The report also sets the stage for formulating alternative, more sustainable scenarios for the region, which include identifying and promoting policy decisions that could boost sustainable practice.
