Mayor Releases Phased Timeline for Park Slope Street Maintenance Program

The New York City mayor issued an updated implementation schedule on July 7 for the Brooklyn Street Maintenance Program, directing $85 million in city funds toward resurfacing and drainage upgrades across 120 blocks in Park Slope. The schedule assigns work crews to specific streets in four phases running from December 2026 through September 2027. Residents on blocks designated for phase one will receive mailed notices 30 days before crews arrive.

The timing follows passage of the city’s fiscal year 2027 budget in June, which increased the Department of Transportation allocation for local resurfacing by 18 percent over the prior year. Park Slope falls inside Community Board 6, an area that recorded 47 pothole complaints per 1,000 residents in 2025 according to the department’s annual service report. The new schedule responds to those volumes by front-loading work on streets with the highest complaint counts.

Sequence of Work and Resident Notifications

Phase one covers 32 blocks bounded by Union Street, 4th Avenue, 9th Street and Prospect Park West. Work on those segments is listed to begin December 1, 2026, and finish by February 28, 2027. Subsequent phases shift westward and northward, with final segments on 15th Street scheduled for completion in September 2027. The Department of Transportation will post updated maps on its website each month and will operate a dedicated hotline for residents seeking exact start dates on their block.

During active construction, the city will close one lane of traffic and restrict parking on the affected side of the street between 7 a.m. and 5 p.m. on weekdays. Alternate-side parking rules will remain in effect on the opposite side. Local businesses within 200 feet of work zones will receive permits allowing temporary loading zones outside normal hours. The program document states that each block will be completed within 10 working days once crews begin.

Budget documents released with the schedule list $22 million earmarked specifically for Park Slope resurfacing, with the remainder directed to adjacent neighborhoods in Brooklyn. The figures appear in the Department of Transportation’s capital plan attachment to the June budget resolution. No additional local taxes are required for the work; funding comes from existing city revenue sources already approved by the council.

Next Steps for Residents

Community Board 6 will hold a public information session on August 12 at the Park Slope Armory to review the block list and answer questions about traffic impacts. Residents may submit written comments on the schedule through the board’s website until August 20. The Department of Transportation is required to publish a final block-by-block calendar by October 1, 2026, incorporating any adjustments made after the session.
