Changing (Part 4 of 7)

Core idea

The fourth part of Changing details the Riverside Park spending. The 4.7 miles north of 110th Street — the stretch including Harlem — received $7,900,000 in development funds (about $1.7M/mile). The 2 miles south of 110th Street — the affluent stretch — received $16,300,000 ($8M/mile). The asymmetry was 4.7x. Caro lays out the budget records to demonstrate that this was not engineering need; it was design choice.

Why it matters

The budget records

Caro reproduces the spending. South of 110th: lavish ornamental stonework, multiple sports facilities, dedicated pedestrian bridges, marble. North of 110th: minimal landscaping, fewer facilities, less maintenance. The records make the asymmetry impossible to attribute to engineering necessity.

The design choices

Specific examples: north of 110th, the park had no marina; south of 110th it had two. North of 110th, the park had two playgrounds; south of 110th it had eight. North of 110th, the bench-per-mile count was a fraction of south. These were not technical limitations; they were Moses's choices.

Practical application

Example

Modern disparate-impact litigation increasingly relies on the same evidence — per-school per-pupil spending records to demonstrate segregated funding, per-loan per-borrower interest rates to demonstrate discriminatory lending. The budget record is the strongest evidence.
