"""NYCHA Developments (NYC OpenData phvi-damg).

326 public-housing developments across NYC. Used as an asset class for
the bulk-mode register; the parent rationale for surfacing this layer
is that NYCHA was hit hard by Sandy and remains a published Tier-1
flood-resilience priority in the city's Hazard Mitigation Plan.
