Sometimes, it’s the little things that make a big difference. Manuel de Dios Unanue Triangle provides a speck of green along Roosevelt Avenue in the packed Jackson Heights neighborhood, but for years, there was nowhere to sit.

Even the brick wall surrounding the trees was topped with two spike strips to discourage people from resting for more than a minute. While the spikes remain, the space now has the foldable chairs and tables familiar from other plazas across the city — and on this beautiful spring day, they are well-used.

The changes are part of Viva La Primavera, a series of public classes and free concerts at the triangle on Thursdays, Fridays, and Saturdays this May. The initiative is a project of the proposed Jackson Heights-Corona Business Improvement District, the 82nd Street Partnership, the Department of Parks and Recreation, Partnership for Parks, Neighborhood Plaza Partnership, the Queens Chamber of Commerce, Council Member Julissa Ferreras, and sponsor Affinity Health Plan.
