Cortlandt Manor — this is where our yard is
Our trucks, our equipment and our material are at 45 Sprout Brook Road, Cortlandt Manor. Everything else we do runs out of here, which makes this the one town where the answer to "how soon can somebody look at it" is usually the same day.
It matters more in winter than at any other time. A commercial snow route is built around where the equipment starts, and this is where ours starts — so a Cortlandt property is at the front of the route rather than at the end of it. In summer it means a crew can come back to finish something in an afternoon rather than scheduling a return trip.

Wooded hills, steep slopes, and soil that holds water
The Town of Cortlandt describes its own terrain as numerous wooded hills and steep slopes, and it is accurate. The town runs from the Hudson River on its west up into the hills toward Yorktown, with Blue Mountain Reservation's fifteen hundred acres and the summits of Blue Mountain and Mount Spitzenberg in the middle of it. Almost nothing here is flat.
Soil is the part worth knowing about, and there is a documented example rather than a generalisation. In the environmental review of one Cortlandt subdivision, New York City's environmental protection department wrote that the majority of the soils in the part of that site inside the city's watershed were Woodbridge loams — noted specifically for seasonal wetness and slow permeability — and required a witness for the infiltration testing because of it. That was one six-acre area of one thirty-six-acre site, so it is an illustration of what this ground can do, not a survey of the town.
What makes it worth knowing is the mechanism, which is general to the till here. Woodbridge and its relatives sit over a dense, compacted layer that water will not readily pass through, so a property can be bone dry in August and have standing water in April, and a dry well that worked on one street fills up permanently on the next.
For construction that means two things. Drainage has to be designed for water that moves sideways over a dense layer rather than downward through it. And infiltration solutions get a test pit before they are promised, because on soils like these they frequently will not work.
What Cortlandt properties actually need
Drainage first, because the soil demands it. Curtain drains intercepting water on a slope, foundation perimeter drains where it is already reaching the house, downspout collection routed properly to daylight, and regrading where the fall around a building is wrong. On Woodbridge soils the answer is almost always to move water rather than to soak it away.
Commercial snow and ice, because this is where the route starts. The Crompond Road corridor around the hospital campus carries a real concentration of medical and institutional property, and those are buildings for which winter access is not a convenience.
And walls, because the slopes are here. Cortlandt's grades are longer and more wooded than Mahopac's lake-slope lots, which tends to mean fewer, larger walls rather than terraces.
Cortlandt's watershed line runs through the middle of the town
Cortlandt is the one town in our service area that is only partly inside New York City's water-supply watershed, and the distinction is practical rather than academic. The town runs from the Hudson River on its west up into the hills toward Yorktown, and its own stormwater management plan draws a line through it: interior areas fall inside the East-of-Hudson NYC DEP watershed, and the rest does not.
You can tell which side of that line a property is on by what triggers a stormwater plan. Inside the watershed area the town applies a 5,000-square-foot land-disturbance threshold. Outside it, the threshold is the statewide one acre — 43,560 square feet. That is a difference of roughly nine to one, and it turns entirely on where the parcel sits.
There IS a published retaining-wall rule here and it catches people out, because it is not a building-permit clause and it is not filed where you would look for one. Cortlandt's dimensional regulations set fence and wall heights — six feet in a front or side yard, eight in a rear yard — and the same section goes on to require that any retaining wall with an exposed face greater than four feet, and any impervious surface within twenty feet of a lot line, be approved by the Town Engineer for drainage adequacy. That is a drainage approval rather than a building permit, and it is a separate question from whether a building permit is also needed, which we confirm with Code Enforcement per job.
Permits, along with the town's separate steep-slopes and wetlands permits, go through the Code Enforcement Division of the Department of Technical Services.

Questions we get in Cortlandt Manor
How fast can you get here?
Faster than anywhere else we work — the yard is on Sprout Brook Road. For estimates that usually means same or next day. For snow it means a Cortlandt property is near the start of the route rather than at the end of it, which is the difference between being cleared before the first shift and being cleared after it.
My yard is soaking wet every spring and dry all summer. Why?
That pattern is what a dense layer in the subsoil does. Soils of the Woodbridge type — documented on at least one Cortlandt site inside the city watershed, and typical of the lodgment till through this region — sit over a compacted layer water will not pass through, so in the wet months it perches on top of it and moves sideways instead of draining down. It is not a groundwater problem and it will not be fixed by a deeper hole; it needs intercepting and routing. Which soil is actually under your lot is a question a test pit answers in an afternoon.
Will a dry well fix it?
Often not on this ground, and we would rather say so than sell you one. A dry well needs soil that will accept water. Over a dense till layer it fills and stays full. We dig a test pit and find out before recommending infiltration; where the soil will not take it, the water gets routed to daylight instead.
Is my property inside the New York City watershed?
It depends where in the town you are — Cortlandt straddles the boundary, which is why the town's own stormwater plan has to distinguish between the two halves. It matters because inside the line a stormwater plan is triggered at 5,000 square feet of disturbance instead of an acre, roughly nine times tighter. We check the parcel against the mapped boundary as part of quoting rather than assuming either way.
