Tree-lined blocks of brownstones and limestones beside Prospect Park make Park Slope beautiful, and they make its sidewalks some of the most root-damaged in Brooklyn.
Park Slope concentrates two problems on the same block: large old trees that lift and crack flags, and a streetscape of stoops, areaways and iron fences that leaves almost no room to fix them. Add the historic district's material rules and a simple flag replacement needs real planning.
We saw-cut precisely, protect stoops and areaways, hand-work the tight sections and pour flags shaped around the roots rather than through them. Where the Landmarks Preservation Commission has a say in materials, we confirm the requirements first so the finished work passes both DOT and LPC scrutiny.
Park Slope's street trees are a big part of its character, but their roots lift flags, open cracks and create the half-inch trip hazards that trigger DOT violations. Add stoops, areaways and tree pits packed closely together and there is not much room for error when a flag has to be replaced.
Much of the neighborhood is a landmarked historic district. We plan repairs so the new concrete matches the block, tree pits are handled properly and any material requirements from the Landmarks Preservation Commission are respected.

Answers to what Park Slope property owners ask us most.
If your building is in the Park Slope Historic District, the Landmarks Preservation Commission has rules about sidewalk materials. Like-for-like concrete repairs are usually straightforward, but bluestone and visible material changes need approval. We check what applies to your block before work starts.
Yes, that is normal Park Slope geometry. We saw-cut precisely, protect the stoop and areaway, and hand-work the sections where machines will not fit.
NYC law makes the adjacent owner responsible for sidewalk condition regardless of what caused the damage. One- to three-family homes may qualify for NYC Parks' Trees & Sidewalks Program, but the waitlist is long and an active violation usually cannot wait for it.
Mostly trip hazards: a vertical difference of half an inch or more between flags, which is exactly what root heave creates. Cracked, patched and ponding flags are also cited.
Yes. Roots are not cut without approval. We regrade, enlarge the tree pit where possible and pour flags shaped to give the trunk room to grow.
