We thank the New York Times for their powerful editorial linking the future of urban America to the pervasive racial and economic segregation that exists in nearly every metropolitan area. Nowhere is this a more vital issue than in the tri-state region centered on New York City. In spite of our diversity, the New York region has one of the highest levels of segregation in the United States, a fundamental cause of our high levels of inequality in income, education and health.

While no single policy can undo this legacy, we can’t truly expand opportunity without changing zoning and other regulations that determine where affordable housing can be built. This doesn’t require building tall apartment buildings where they don’t belong. Accessory dwelling units, two-family homes and mid-rise buildings can expand housing options that are appropriate for individual communities. But it will require a more active role by state governments to set standards, enforce fair housing laws, and provide resources to municipalities where needed. While New Jersey’s Council on Affordable Housing gives it a framework to build on, Connecticut has weaker legislative requirements and New York State has none.
