Establishes an economic grant program for the Second Avenue Subway construction project area

S 1370 creates a grant program to support businesses directly impacted by Second Avenue Subway construction in specific Manhattan areas (including 2nd Avenue corridors and surrounding streets). It provides financial aid to "qualified businesses" (small/micro businesses within 150 feet of construction zones showing at least a 10% income decline) for capital improvements (like signage, noise reduction, and ventilation), marketing, and operational costs. Severely affected businesses ("endangered" with 30% loss or "terminal" with 50% loss) receive additional support, including payroll assistance, rent help, and business closure services. The program also includes technical assistance and marketing grants to help businesses recover during construction. This bill aims to mitigate economic disruption for local businesses during the subway project.
