Accessible Historic Streetscapes

March 22, 2018

New York City is an ever growing city with many layers of history which affect the people who call it home, and visit it. Parts of the city are still lucky enough to retain their historic Belgian Block street pavings. In Historic Districts the Belgian Blocks should be preserved and replaced in kind after road work, but in recent years these streets have been paved over in the name of being American with Disabilities Act compliant.

In this class attendees will learn about the historic pavings used in DUMBO and around New York City from Doreen Gallo. Based on a study the Historic District Council commissioned from Being Here Landscape Architecture & Environmental Design, PLLC,  Denisha Williams and Jeff Byles will explain how to maintain the historic Belgian Blocks while being American with Disabilities Act compliant.
