Swing or Slide Gate on a Sloped Austin Driveway

On a driveway that climbs even a few feet across the opening, the swing versus slide question stops being a matter of taste. The running record austin driveway gates the derek bordeaux group holds shows the same pattern on lots in Travis Heights, Tarrytown and out toward the Texas Hill Country: the slope settles the choice before anyone picks a style. A gate in Austin, TX has to clear the pavement at its lowest point and still sit level enough for the latch to meet the post.
What a swing gate needs from the ground

A single swing leaf rotates on its hinges, so the bottom rail sweeps an arc over whatever the driveway does inside that arc. If the pavement rises toward the house, the leaf has to be hung high enough to clear the rise at the far end of its swing, and that leaves a wide gap under the gate on the low side. A dual swing pair doubles the problem, because each leaf sweeps its own arc. Crews answer it with a rising hinge, a raised frame, or a bottom rail cut to follow the grade.
Why a slide gate ignores most of the slope

A slide gate rolls along the fence line and never swings over the driveway at all. The pavement can fall away toward the street and the gate still travels straight. The cost is space: the gate needs a clear run beside the opening equal to its own length, and on a narrow lot near Hyde Park or Clarksville that run is often where the project ends.
Track slide or cantilever gate on uneven ground
A track slide carries the gate on wheels in a ground channel, and dirt, leaves and gravel wash into that channel after every storm. A cantilever gate hangs from rollers on posts and keeps the bottom rail clear of the ground, so grade matters less. It needs a counterweight tail behind the opening.
Clearance at the low end and the high end
Every fabricator checks clearance at both ends of the opening, not at the middle. The low end sets how close the bottom rail may sit to the pavement, and the high end sets how far the leaf can swing before it touches the rise. A drive above the Colorado River bluffs or a lot near Mount Bonnell can change a full hand's width of grade across ten feet of opening. A miscount shows up as a gate that drags or a gap a dog can walk through.
Choosing between them
Steep, short openings with room inside the fence favor a cantilever or slide gate. Flat, wide openings with room to swing favor a single or dual swing pair. Mixed lots, where the slope is moderate and the setback is tight, often call for a swing gate on a taller hinge post and an operator with an actuator arm that suits the angle. Grade, setback and fence length decide it, in that order.
