Standing water isn’t just an eyesore. On a Dix Hills property, it’s a slow drain on everything you’ve invested your lawn, your foundation, your landscaping, and ultimately your home’s value. When drainage works the way it should, the soggy patches dry out, the dead grass grows back, and the water that used to sit against your foundation starts moving away from it instead.
Dix Hills sits on glacial moraine terrain rolling, clay-influenced soil that holds water instead of letting it pass through. That’s a fundamentally different drainage challenge than what you’d find on Long Island’s flat, sandy South Shore. Water doesn’t just pool here it flows in complex paths across sloped lots, collects at low points, and runs toward whatever is downhill, which is often a foundation wall or a neighbor’s yard. A drainage system that works here has to account for that movement from the start.
The homes in this area most of them large Colonials and split-levels built between the 1960s and 1990s were constructed before modern stormwater standards. Original grading shifts over decades. Mature trees disrupt underground infrastructure. Long driveways, pool decks, and patios create large impervious surfaces that push water somewhere it wasn’t designed to go. Solving that isn’t a one-drain fix. It’s a site-specific system built around how your property actually behaves.
Gold Coast Landworks is a Long Island landscape drainage company that works across Suffolk County including Dix Hills, Commack, Melville, Huntington, and the surrounding communities in the Town of Huntington. We specialize in landscape drainage, not plumbing. That distinction matters more than most homeowners realize until they’ve called the wrong type of contractor first.
What sets our work apart is what happens before installation. Every project starts with a thorough site assessment mapping where water originates, how it travels across your property, and where it needs to discharge. Skipping that step is the reason most drainage fixes fail. A single French drain installed without understanding the full water flow path on your Dix Hills lot is just an expensive experiment.
We’re licensed and insured for work in Suffolk County, and we handle everything from the initial assessment through installation through full yard restoration. When we leave, your property should look better than it did before not like a construction site.
It starts with a site visit. We walk your property and map the full water flow where it’s coming from, where it’s going, and where it’s causing damage. In Dix Hills, that often means accounting for grade changes across a large lot, runoff from hardscaped surfaces like driveways and pool decks, and soil conditions that don’t drain the way sandy soil would. We’re also looking at how your downspouts are routed and whether the original grading on your home many of which were built decades ago is still doing its job.
From there, we put together a written proposal that outlines exactly what will be done, what materials will be used, and what the project will cost. No verbal estimates, no scope surprises. If permits are required under the Town of Huntington’s stormwater management code, we handle that as part of the process not as an afterthought.
Installation is followed by complete restoration of any disturbed turf, topsoil, and landscaping. In a community where mature plantings and established landscaping are the norm, that matters. We don’t consider the job done until the system works and the yard looks right.

The drainage issues on a large, wooded Dix Hills lot are not the same as what you’d find on a smaller, flat lot in a neighboring community. The rolling terrain, the clay-influenced glacial soil, the mature tree canopy, and the large impervious surfaces all shape how a drainage system needs to be designed here. That’s why our work starts with a real assessment not a standard package applied to every property regardless of conditions.
Depending on what the site assessment reveals, the solution might involve French drain installation, catch basin placement, dry well installation, regrading, downspout rerouting, or a combination of several. Some properties north of the LIE have different grade profiles than those to the south and that affects where water collects and how it needs to be redirected. Every system we design is built around your specific lot, not a template.
All drainage systems are designed to comply with the Town of Huntington’s stormwater management requirements, including proper discharge point routing that doesn’t direct water into the Town’s storm sewer system in violation of local code. Suffolk County sits above the Long Island Aquifer the sole drinking water source for the island and responsible drainage design accounts for that. You get a system that works, is code-compliant, and is built to handle peak storm loads, not just average rainfall.
This is one of the most common situations we run into on Dix Hills properties. The most frequent reason prior drainage work fails isn’t poor installation it’s an incomplete assessment before the work began. Installing a single French drain or catch basin without mapping the full water flow path on your property just moves the problem, it doesn’t solve it. Water will find the next low point and pool there instead.
In Dix Hills specifically, the rolling morainal terrain means water travels in complex patterns across sloped lots. A drain installed in the wrong location or sized for average rainfall rather than peak storm loads will underperform every time conditions get serious. The August 2024 flooding across northern Suffolk County showed exactly how fast that gap becomes a problem. If your previous fix didn’t hold, the answer is a full site assessment that maps the entire water flow before anything else is decided.
If your yard is flooding after rain, you don’t need a plumber you need a landscape drainage contractor. Plumbers fix pipes inside your home: clogs, leaks, sewer lines. We fix the way water moves across and through your land the grading, the surface flow, the soil saturation, the runoff from your driveway or pool deck.
Search for drainage help in Dix Hills and you’ll find plumbers showing up prominently in results. That’s a real source of confusion for homeowners. Calling a plumber for a yard drainage problem won’t hurt anything, but they’ll typically tell you there’s no pipe issue and send you on your way which doesn’t solve the standing water in your backyard. If the problem starts outside and involves how water moves across your property, that’s a landscape drainage problem, and a landscape contractor is the right call.
Residential drainage projects in Suffolk County typically range from around $2,000 to $7,500 for most standard installations, with French drain work running roughly $10 to $50 per linear foot depending on depth, materials, and site conditions. Larger or more complex properties which are common in Dix Hills given the lot sizes and terrain can run higher depending on how much excavation and restoration is involved.
The more useful comparison isn’t what drainage costs it’s what it costs to skip it. Foundation repair from water intrusion runs $23,000 to $48,000. A single water damage insurance claim averages around $13,954. One inch of floodwater causes an average of $27,000 in home damage. For a home valued above $1 million in Dix Hills, a properly installed drainage system isn’t a large line item it’s the cheapest form of structural protection available. Every dollar invested in flood prevention is estimated to save $5 to $8 in downstream damage costs.
It depends on the scope of the project. The Town of Huntington has a stormwater management code Chapter 170 that governs how stormwater is handled and discharged on residential properties. Drainage systems that discharge to the Town’s separate storm sewer system (MS4) are subject to specific rules, and not all discharge configurations are permitted without review.
For most standard residential drainage projects in Dix Hills, permits are not required. But for larger installations, projects involving significant grading changes, or work on properties near regulated areas, permit requirements can apply. New York State’s SPDES permit program also kicks in for any construction activity disturbing one or more acres of soil something that can come into play on larger estate lots. Part of what we do during the assessment phase is determine what regulatory requirements apply to your specific project before any work begins, so there are no surprises mid-job.
Most residential drainage installations in Dix Hills take one to three days on-site, depending on the complexity of the system and the size of the property. Larger lots with multiple drainage components catch basins, French drains, dry wells, and regrading combined naturally take longer than a straightforward single-drain installation.
The site assessment and written proposal phase typically happens before scheduling, so by the time work begins, the plan is already finalized. Weather and soil conditions can affect scheduling, particularly in early spring when the ground is still recovering from freeze-thaw cycles and saturation levels are high which is also when many Dix Hills homeowners first notice drainage problems that developed or worsened over winter. We’ll give you a realistic timeline during the assessment and keep you informed if anything changes. Full yard restoration is included in the project scope, so the timeline accounts for that as well not just the drainage installation itself.
The most common issues we see in Dix Hills come down to a few consistent factors. First, the terrain. The rolling morainal topography means elevated lots naturally shed water toward lower ground and if your property sits downslope from a neighbor, you may be collecting runoff from multiple uphill sources. Second, the soil. Clay-influenced glacial till doesn’t drain the way sandy soil does. Water sits at the surface, saturates the lawn, and runs toward the nearest low point instead of percolating down.
Third, the age and size of the homes. Most Dix Hills properties were built between the 1960s and 1990s, before modern stormwater standards. Original grading has shifted over decades. Mature tree roots have disrupted underground infrastructure. And large impervious surfaces long driveways, pool decks, patios, sports courts push significant volumes of water somewhere during every storm. Those aren’t separate problems they’re usually symptoms of the same drainage gap, and they’re best addressed as a system rather than one component at a time.
