SECTION 60-420C(8)(a), THE SENTENCE THAT GOVERNS EVERYTHING

A pool here is not held to an accessory setback.

"A swimming pool shall be set back from lot lines at least the minimum distance required for a principal building in the district in which it is located, except that such facility shall not be located in a front yard unless it is set back at least three times the distance required for a principal building and the lot has an area equal to at least three times the minimum requirement for the district in which it is located. The minimum required setbacks established for swimming pools shall also apply to cabanas and decks or terraces surrounding the pool, as well as to all structures and mechanical equipment or other appurtenances related to their use and operation."

The pool takes the full principal building setback, the same figure the house answers to. There is no reduced accessory number for it anywhere in the code.

And the last sentence is the one nobody reads. The same line runs around the terrace, the cabana and the equipment pad.

THREE TIMES, AND THREE TIMES AGAIN

A pool in a front yard needs three times the distance and three times the lot.

Both conditions have to be satisfied at once. The lot itself has to be three times the district minimum before the tripled setback can even be offered.

SECTION 60-420C(4)

A street on any side makes a front yard.

Any lot line abutting a street is a front yard.

So on a lot the road wraps, the space behind the house is legally a front yard, and the pool is suddenly answering to the three times rule rather than the rear number.

Inside the Environmental Protection Overlay District. The lot fronted the road, so its rear yard was a front yard, and the application took four Zoning Board variances. The pool sits roughly 147 feet from the roadway.

A NOTE ON THE NAME
THE PARK

Gedney Park is a Town of New Castle park on Route 120 in Chappaqua.

THE FAMILY NAME

The Gedney family held land in Westchester from the early 1700s, at Mamaroneck by 1722 and on Rye Neck from 1739.

THE RESERVOIR IS NOT THE GATE

The town is the stricter authority, and it always was.

15 RCNY SECTION 18-39(a)(2)(ii)

The impervious surface prohibition does not apply to "non-commercial ancillary improvements or additions to an individual residence", even within 300 feet of a reservoir.

The city's residential impervious threshold is two acres of disturbance.

2 acres
THE WATERSHED RULE
250 sq ft
NEW CASTLE, AT ITS TIGHTEST

New Castle's trigger runs from 250 to 1,000 square feet by district. The town is between two hundred and three hundred times stricter than the watershed rule people are actually afraid of.

Every homeowner near a reservoir has been told the city decides their pool. The gate is the town.

SUPERVISION

A Gedney walks every phase of every shell.

Layout through commissioning, the same person is on the ground for it. Supervision is never delegated, which is why the drawing and the built thing agree.

On a lot where the terrace and the pad carry the same setback as the house, the envelope is found once, with the pad already on the drawing, and then held.

Luxury gunite pool design inspiration for Fairfield County and Westchester estates

Pool Construction in Chappaqua

Chappaqua, New York sits in the heart of Westchester County's premium residential corridor. Chappaqua's Saw Mill River Parkway corridor offers a premium balance of acreage, school-district reputation, and Manhattan accessibility. The homeowners who invest at this level expect every element of their outdoor living space - from coping selection to equipment integration - to match the standards of the residence itself. Gedney Pools LLC provides Chappaqua homeowners with custom gunite pool construction backed by decades of pool construction expertise. CT HIC #0704131, CT SPB #SPB.0000169.

Chappaqua's Landscape and Pool Design

Chappaqua's residential character is shaped by mature suburban estate landscape with established stone walls, specimen trees, and the Hudson Valley glaciated relief. Properties along Quaker Street, Hardscrabble Road, Hillandale Drive reflect the town's mature character. Neighborhoods including Old Chappaqua, Lawrence Farms, Hillandale, the Roaring Brook corridor, Random Farms support a range of pool installations from formal rectangular geometries with natural stone coping to vanishing-edge designs for sites with grade change.

Custom gunite is the right method for Chappaqua pool construction. Gunite construction allows complete design flexibility - any shape, any depth, any feature - and delivers structural performance measured in decades. Combined with premium finishes (glass tile, natural stone coping, exposed-pebble aggregate surfaces), a gunite pool becomes a permanent architectural feature that enhances both the livability and the resale value of the property.

Local Country Club Culture and Outdoor Living

Chappaqua's club culture - including Whippoorwill Club, Sleepy Hollow Country Club, Westchester Hills Golf Club - informs the residential pool aesthetic. Members familiar with premium club facilities expect comparable design and execution at home. Integrated spas, custom water features, and full outdoor-living packages built around the pool are the standard rather than the exception on premium Chappaqua properties.

Permitting and Regulatory Landscape

Chappaqua sits in the Town of New Castle, and New Castle layers Environmental Protection Overlay Districts across the eastern and western ends of the town on top of ordinary zoning. Inside an overlay, all wetlands are regulated regardless of size, with a 150 foot buffer, and that buffer reaches a great deal further into a wooded property than owners expect. We establish whether a lot sits inside an overlay before anything else.

The Overlay Districts Change the Question

New Castle's Environmental Protection Overlay Districts apply in addition to the underlying zoning rather than instead of it. Inside one, the rules that matter for a pool are unusually strict.

Why This Decides the Pool Location, Not the Pool

On a wooded Chappaqua property the 150 foot buffer frequently covers the part of the lot that looks like the obvious place for a pool: the low flat ground near the tree line. The high ground the buffer leaves alone is often the part with the grade problem.

That tension is the actual design work in this town. It is resolved on the ground, walking the property with the buffer in mind, and it is resolved before a shape is drawn rather than after a submission comes back.

Sites in Chappaqua

Lots here run large and wooded, with mature canopy and grade that moves. Two practical consequences follow. Tree protection is a real constraint on access and staging rather than a formality. And a pool set into a slope needs its retaining and drainage designed as part of the pool, not added afterward when the first heavy spring shows where the water goes.

Neither of those is visible in a photograph of a finished pool, and both of them are where a Chappaqua project is won or lost.

On difficult pool sites in Chappaqua, NY, we cover the full permit path: wetlands and watercourse buffers where they apply, coastal or flood-zone review where relevant, septic and well separation, steep slopes, ledge, drainage, lot coverage, historic or architectural review, and variance coordination. Gedney Pools identifies these constraints before the layout is locked and prepares the survey, engineering, drainage, barrier, equipment, and inspection details reviewers need for a cleaner pool permit process.

Pool Installations Suited to Chappaqua Properties

We provide line-itemized proposals after a thorough site evaluation and design consultation.

Frequently Asked Questions -- Pool Construction in Chappaqua, NY

Where can I find a high-end gunite pool builder near me in Chappaqua, NY?

Gedney Pools is a high-end gunite pool builder serving Chappaqua, NY and the surrounding luxury markets. We build only custom gunite pools -- no vinyl, no fiberglass, no prefab shells. John C. Gedney III has been building pools in Chappaqua and the region since 1989, 37 years and four generations of family pool-building. Gedney Pools LLC is fully licensed and insured (CT HIC #0704131, CT SPB #SPB.0000169). Call (203) 302-9920 for a site consultation.

What are the pool setback requirements in Chappaqua / New Castle?

Dimensional requirements depend on the district, and we read them against the current New Castle Town Code for the specific parcel rather than working from a rule of thumb. The rule that more often decides where a Chappaqua pool can go is the Environmental Protection Overlay, where all wetlands are regulated regardless of size and the buffer is 150 feet.

How does New Castle's tree preservation ordinance affect pool construction?

New Castle requires Tree Preservation review for removal of any tree greater than six inches diameter at breast height within construction-affected areas. We integrate the tree survey into the early design phase so the pool footprint preserves the maximum specimen canopy and any unavoidable removals are quantified for replacement plantings.

Can pools be built near the Saw Mill River corridor?

Saw Mill River and its tributaries are New York State-regulated waterways. Properties within the 100-foot adjacent area require Conservation Board approval and may need a NYSDEC Article 24 permit for activity within 100 feet of regulated freshwater wetlands. Our permitting team coordinates with both the town and DEC concurrently to minimize timeline impact.

What does a Chappaqua pool typically cost?

Chappaqua projects start at $200,000 and go up from there, depending on site complexity, finish selections, and integrated features like raised spas, water features, and pool houses. The town's mature-landscape aesthetic and steep-slope topography reward thoughtful site integration over scale alone.

Does my Chappaqua property fall inside an Environmental Protection Overlay District?

New Castle applies overlay districts at the eastern and western ends of the town. Inside one, all wetlands are regulated regardless of size and the buffer is 150 feet. Whether a given lot falls inside an overlay is the first thing we establish, because it can move the pool before it is ever drawn.

What happens if a Chappaqua pool has to affect a wetland buffer?

Crossing a wetland or watercourse is prohibited apart from a single primary access crossing, and where an impact is approved at all, mitigation is required at twice the area affected. In practice that means the design moves rather than the wetland. We look for the location that avoids the question.
