“The reality is every time the public makes an investment in a community, whether it's a park, an improvement of a school or a piece of transit, the real estate owners are the ones who benefit,” said Walentas. “We need a system for these real estate owners to give back more than they are now and to figure out a way to use that value to finance these kinds of pubic goods.”

Two Trees owns several properties along the waterfront, close to where the BQX would run. The Walentas family business is well know for its investments in Brooklyn, particularly having influenced the shape and character of Dumbo.

Dani Simons, the vice president for strategic communications at Regional Planning Association, said rezoning and redevelopments can also raise money from developers. She cited the Midtown East rezoning which in addition to increasing tax revenue also requires developer funding for subway infrastructure improvements.

“Zoning is a way to pay for things,” said Walentas. “You are creating value out of thin air to create a public resource.”

The moderator, Vishaan Chakrabarti, also on the board of directors of the Friends of the BQX, is an architect and the founder of Practice for Architecture and Urbanism. He added with a smile, “I used to tell my students the only way to legally print money in the United States is the Federal Reserve and upzoning.”

In addition to transportation, the panelists cited affordability and equity as two other areas in which New York City needs improvement. “Whether you are low income or middle income, unless you are the top 1%, this is a tough place to live,” said Simons. In looking at ways to make the region more affordable, availability of housing and better transportation to the housing would allow people to work in wider geographic regions.

Panelist Bishop Mitchell G. Taylor who grew up in Queensbridge appreciates transportation that would not require going to Manhattan to travel between boroughs. As the co-founder and CEO at Urban Upbound, Taylor sees alternative transportation for people who do not live close to subway lines, including waterways, light rails and Citibikes, as increasing the opportunity to move from poverty to prosperity. In addition, according to Simons, most of the job growth she has observed is occurring outside of Manhattan's central business district.

Panelist Serkan Piantino is the founder and CEO of Spell. Previously, he worked at Facebook where he led the development of products including the News Feed, Timeline and Messenger. He appreciates that New York is not a one industry town—and not just tech.

“You get to interact with people of all walks of life,” says Piantino. “Diversity really is the genuine reason why people prefer New York to other places to start a company. People come here with more curiosity about what's going on around them than they do in other places.”

At the Brooklyn Navy Yard, last week Mayor Bill de Blasio celebrated opening one of the largest manufacturing spaces in decades, Building 77. The $185 million renovation of the WWII -era storage facility, a one million square-foot, state-of-the-art manufacturing structure, is a milestone in the mayor's plan to create 100,000 good paying jobs across a range of industries.

At the Building 77 opening, the Brooklyn Navy Yard also launched its search for a tenant to transform the rooftop space into creative uses. The 24,000 square-foot space on the 16th floor includes approximately 8,011 square-feet of interior space and 16,456 square feet on the adjacent outdoor roof.
