General Electric will use Union Point as a laboratory for testing new products and as a showroom for working systems. Eric Gebhardt, the strategic technology officer at GE Power, said the community’s energy plan will include micro grid technology, renewable generation and power storage. The company will also install “intelligent” lighting — streetlights with sensors that can track sound, light and other conditions. The data can be used to monitor traffic, help drivers find parking spaces and alert law enforcement if a gun is fired.
G.E. has piloted some of its smart products in existing cities, but Union Point is an unusual opportunity because most of the infrastructure does not exist yet and the developer is open to experimentation, Mr. Gebhardt said.
LStar plans to open an innovation center in the air station’s old power plant. The center has expressed an interest in featuring an interactive planning tool developed by the Massachusetts Institute of Technology City Science Group called CityScope, which could aid in Union Point’s evolution by allowing users to visualize and explore trade-offs around factors like density, transportation and walkability, said David Rose, a researcher and lecturer at MIT’s Media Lab.
LStar wants “the center to be a showcase for what the city could be, a place to monitor what it is becoming, and a place to ask existential questions like, ‘Could it be more inclusive, say, or energy efficient?’” Mr. Rose said.
LStar also has an agreement with Optimus Ride, an autonomous vehicle start-up in Boston, to set up a self-driving vehicle service at Union Point. The company is already testing its electric vehicles at the property.
Union Point’s first commercial tenant is expected this spring, when Prodrive Technologies, a Dutch company that develops and manufactures products for the automotive, medical and other industries, will break ground on its 60,000-square-foot United States headquarters. The site’s proximity to Boston, access to commuter rail service and ample room for expansion were crucial to the firm’s location decision, said Roy Willems, the company’s general manager of United States operations. He said Prodrive expected to build a second 200,000-square-foot building within three years, and increase its work force to roughly 300 people.
LStar had to persuade the three host communities to approve critical zoning changes before it could move forward with the project. They also granted the developer considerable latitude over the design and layout of the community, which will take shape over 15 to 20 years.
“The three towns recognized an opportunity to do something quite extraordinary” on a site where previous development plans stalled, said David P. Manfredi, a founding principal at Elkus Manfredi Architects, which helped create the master plan for Union Point. “This is an alternative to what could have been suburban sprawl.”
Union Point promises to bring badly needed tax revenue to Weymouth, said the town’s mayor, Robert L. Hedlund. “It’s the commercial build-out that we’re lusting after,” he said.
Still, similarly ambitious smart city projects have proved perilous. Mr. Rose cited Songdo, a smart city nearing completion in South Korea, as a prime example. The city boasts advanced connectivity, but it has so far failed to meet expectations in attracting international businesses and residents.
“What they got wrong was any sort of sense of streetscape,” said Mr. Rose, who has visited Songdo. “There’s no sense of patina, no authentic street life. It’s super sterile. It was built as this fantasy of the future, but it’s a place that humans don’t want to occupy.”
The integration of technology into urban planning has prompted questions about how the data being collected will be used. In Toronto, for example, Sidewalk Labs, a subsidiary of Alphabet, the parent company of Google, attracted considerable publicity when it was selected last year to help create a smart neighborhood of sorts in a waterfront district called Quayside. Some local officials and critics are questioning whether the deal gives too much authority to Sidewalk Labs without putting limitations on Google’s collection and use of data.
The need for greater regulation of driverless vehicles has also come up for debate after the death last month of a woman who was struck by one of Uber’s self-driving cars in Tempe, Ariz.
“Very few local governments have thought through the long list of public- and private-sector values and concerns that should be deployed to constrain” the use of autonomous cars, as well as the technologies being used to monitor city streets, said Susan Crawford, a Harvard Law School professor. “Once you’ve given a developer license to deploy total surveillance, with no public limitations, you’re done.”
LStar has considerable leeway to test technologies at Union Point. The developer is purposely holding on to its roads, rather than asking for them to be made public ways, to maintain flexibility in testing autonomous vehicles, lighting and other technologies, said Robert Luongo, Weymouth’s director of planning and community development.
“If these were public ways, we might not be able to give them that flexibility,” he said.
Mr. Corkum said retaining ownership of the roads would enable them to play with designs for amenities like drop-off areas for driverless shuttles and heated sidewalks. “It’s better for us to stay in this testing phase until we have good workable solutions,” he said.
State oversight of autonomous vehicles applies only once there is public use, he said. Even then, the rules are vague. Ryan Chin, the chief executive of Optimus Ride, said his company would adhere to the same high-level safety standards and testing protocols at Union Point that it followed for testing driverless cars in Boston’s Seaport neighborhood.
As for privacy concerns, Mr. Corkum said that he believed in setting boundaries on data collection and use. There is value in using technology to improve quality of life by, for instance, alleviating traffic jams, but he said he was wary of falling prey to a “preoccupation with optimization.”
The company is working with law firms and consultants on operating guidelines for gathering and anonymizing data and ensuring it cannot be hacked or used to invade privacy, he said.
“I don’t like the Big Brother notion that we know everything about you,” he said. “We will use data for the benefit of the group, not in a way to leverage the group.”
