Impact analysis

through Jul 19, 2026

Screening-level estimates of the economic and fiscal effects of Northfax Chain Bridge. Figures are decision-support context with named assumptions and sensitivity ranges — not predictions. The full analysis has the interactive assumptions panel and maps; methods documents every formula.

Headline estimates

New residents: 463 (range 366 – 578) — households x persons per multifamily unit (Rutgers CUPR bedroom-mix multipliers)
Annual capture: project's own ground-floor retail: $8,860 (range $5,106 – $12k) — Huff model over individual retail POIs: joint destination+mode choice, P(j,m) ~ A_j * w_m * exp(-b_m t_mj), CES category spend; clusters are a reporting rollup; own retail competes as a destination
New annual spending arriving on foot: $740k (range $128k – $3.9M) — walk-mode share of the joint destination+mode Huff choice, summed over businesses; walking loses to driving with walk time, so the remainder of the mode-split budget arrives by car
Real estate tax increase: $994k (range $988k – $1.3M) — projected minus current RE tax
Net annual fiscal impact — naive per-capita method: −$1.6M (range −$2.5M – −$368k) — incremental new recurring revenue minus service cost (upper-bound cost framing; allocates fixed citywide costs)
Net annual fiscal impact — marginal framing: $15k (range −$1.2M – $1.1M) — incremental new recurring revenue minus service cost (only services that scale with new residents)
