Shirley runs from the expressway down to the bay at Smith Point, and the southern end sits in mapped flood zones. That single fact reorganises how hardscape gets designed here.
Coverage and stormwater are the constraint
In flood-prone areas the rules about how much of a lot can be sealed, and where the water from a sealed surface has to go, are tighter than they are inland. A patio that would be waved through in Selden can require a stormwater approach in southern Shirley.
This is where permeable paving stops being a premium upgrade and becomes the practical answer. It lets water through the joints into an open-graded reservoir below and back into the ground on your own parcel, rather than shedding it toward a neighbor or a road that is already carrying too much.
Building on ground that stays wet
- Open-graded base with clean stone rather than a dense-graded base that holds water
- Geotextile separation so the base does not migrate into soft, saturated subgrade
- Reservoir depth sized for the rainfall the system is meant to hold
- Edge restraint spiked into stable material, not into saturated fill
- Realistic conversation about what happens in a genuine surge event
That last point deserves honesty. A patio in a flood zone can be built well and will still be underwater in a serious surge. What good construction buys you is that it survives the event and can be cleaned and reset rather than needing full replacement. Pavers do that; a poured slab that has been undermined does not.
Salt near Smith Point
Bay-adjacent properties get salt in the air and in the ground. On hardscape that shows as efflorescence — white bloom on the paver faces as salts migrate out. It is cosmetic and it weathers, and the wrong response is a film-forming sealer that traps the salt under a haze.
The components that actually suffer are metal: edge restraint spikes, any steel in adjacent concrete, drain grates and hardware. We specify those for the exposure rather than defaulting to standard inland parts.
Elevated houses need the transition designed
Homes elevated after Sandy have stairs, landings and utility penetrations that did not exist before, and the hardscape has to meet all of it. Where a patio or walkway ties into new stairs and skirting, that junction is the detail that either looks deliberate or looks like two projects that met by accident. It is worth designing together.
Frequently Asked Questions
Do I need permeable paving in a Shirley flood zone?
Often it is the practical answer rather than a premium option. Rules on sealed coverage and where stormwater goes are tighter in flood-prone areas, and a permeable system keeps the water on your own parcel by letting it through the joints into a reservoir below and back into the ground. We confirm what applies to your parcel before designing.
Will a paver patio survive a flood?
It can be built to survive one. In a serious surge event it will go underwater regardless — what good construction buys you is that it cleans up and resets afterward rather than needing full replacement. Pavers can be lifted and relaid; a poured slab that has been undermined cannot.
How long does a paver patio take?
Three to five days for a typical 400 to 700 square foot patio. Most of that is excavation and base work, which is the part you never see and the only part that decides whether the patio is still flat in ten years.
When can masonry work be done on Long Island?
Roughly April through November. Frozen ground cannot be properly excavated or compacted, and polymeric jointing sand needs dry conditions above about 50 degrees to cure. Winter is the right time to design and permit — spring dates fill during March.
