491 PCE in the construction peak hour (6–7 AM), 2028 Q2

50 PCE or more: a detailed construction traffic analysis may be warranted (CEQR TM Ch.22, p.22-5). Construction trips only; for a phased project, add the operational PCEs of completed portions before applying the threshold.

Transit = subway + bus + rail; pedestrians = walk + every transit rider. The 200-trip figures are reference values: CEQR TM Ch.16 Level 1 operational screening thresholds (pp.16-3 to 16-4); Ch.22 sets none for transit or pedestrians, and public FEISs commonly apply them to construction. The formal screen remains 50 PCE in the construction peak hour (p.22-5).
