What it's like building a wall in Centerport
Centerport's defining feature is the ridge dropping toward Centerport Harbor and Little Neck Bay. Lots on Park Avenue, Centershore Road, and the streets off Little Neck Road frequently sit on 15 to 30 percent slopes that require real engineering, not decorative block.
The Centerport neighborhoods we work in most: Little Neck, Centerport Harbor, Vanderbilt area, Park Hill. If you're in or near any of these and need a wall built or replaced, we likely know your street and the soil under it.
The walls Centerport homeowners ask us about
Multi-tier walls cascading from house pad down to dock or beach, slope stabilization where harbor-facing yards are slowly migrating downhill, and driveway walls on the steep entries off 25A.
Last August we replaced an 80 LF tiered timber wall behind a house on Park Avenue. The original timbers had rotted to soft cores you could push your hand through. We rebuilt as two Nicolock Olde Greenwich tiers with planting strips between them. Final invoice was $34,200 including new drainage and a 4-inch outlet pipe daylighting toward the harbor side.
