01 · Premise

Public access is promised uniformly. Public benefit is not.

Privately owned public spaces—or POPS—are provided and maintained by private property owners in exchange for zoning benefits.

If these outdoor plazas share an obligation to provide public access, how consistent is the breadth of amenities they are required to provide?

02 · Study area

One corridor makes unequal requirements easier to see.

The study follows Sixth Avenue from approximately West 42nd to West 57th Street. Holding the corridor relatively constant focuses the comparison on documented requirements rather than broad neighborhood differences.

03 · Method

A reproducible path from city data to an interactive argument.

1Acquire

Download NYC POPS records through the Open Data API.

2Filter

Select Sixth Avenue developments with an outdoor plaza component.

3Parse

Extract plaza area, access hours, and required amenities.

4Score

Compare seven equally weighted amenity groups.

5Map

Export GeoJSON and visualize the corridor with MapLibre.

Documented Provision Score

Seating · Tables · Landscape · Lighting · Public signage · Litter receptacles · Water

Each group contributes equally to a transparent 0–100 score.

04 · Findings

The right to enter does not guarantee support for staying.

15/15

include a 24-hour public-access requirement.

3/15

list no required amenities in the official record.

11/15

require seating—the most direct support for occupying a plaza.

Amenity coverage

Basic occupation and maintenance are common, but not universal.

05 · Interactive map

Provision changes block by block.

Gray dots show all other Manhattan POPS. The outlined boundary marks the study corridor; within it, color and size describe the selected 15.

06 · Contrasts

Comparable access requirements can produce very different records.

07 · Limits

The database maps obligation, not experience.

The official record does not confirm whether amenities are currently present, maintained, welcoming, or equally accessible. Mixed developments may aggregate several public-space components.

Looking forward

The next step is verification.

A future version would compare legal records against current imagery, accessibility audits, and field observations—shifting the question from what is promised to what the public can actually use.
