Concrete Driveway Aprons & Approaches

A concrete driveway apron (or approach) is the section that connects your driveway to the street, and in Oregon it usually sits in the public right-of-way — which means a city permit and a build that meets the city's spec. Because it carries the weight of every vehicle entering and crossing the gutter, an apron needs to be thicker and better reinforced than the rest of the driveway. The two things people miss are the permit (the apron is partly the city's, even though you pay for it) and the transition to the street (it has to match grade and drainage). This guide covers the permit, the thickness, and the transition.
The apron is the transition zone between the public street and your private driveway. It typically spans from the edge of the street or the gutter up to the property line or sidewalk. The tricky part: even though you pay for it and use it, the apron usually lies in the public right-of-way, so the city sets the rules for how it is built and has to approve it. This is why an apron is not just "the end of the driveway" — it is a permitted piece of work. For where it fits with the rest of your concrete, see the concrete services overview.
Replacing or installing an apron almost always requires a city right-of-way permit. The city specifies:
A licensed contractor pulls the permit and builds to the city's standard so the work passes inspection. Skipping the permit risks a stop-work order or a tear-out.
The apron sees more abuse than your driveway: every vehicle entering crosses it, including delivery trucks and garbage trucks at the curb. That is why cities spec a thicker, reinforced apron — commonly thicker than the four-inch standard for a residential driveway, with rebar rather than just wire mesh. Under-building the apron is how it cracks and settles at the gutter within a few years. The thickness logic for the rest of the drive is covered in concrete driveway thickness; the apron is the heaviest-duty part of it.
The connection to the street is where a lot of aprons go wrong. It has to:
On Oregon's wet clay, getting the drainage right at the apron matters — a low spot at the gutter collects water that freezes east of the mountains and undermines the slab. A good apron sheds water to the gutter and away from your property.
| Driver | Effect |
|---|---|
| Permit and inspection | City fee and required contractor |
| Thickness and rebar | Heavier spec than the driveway |
| Demolition of old apron | Haul-off and gutter cuts |
| Width and flare | Larger approaches cost more |
| Curb and gutter ties | Sawcutting and matching grade |
Apron work involves a permit, often a saw-cut into existing curb and gutter, and a heavier concrete spec, so it costs more per square foot than plain driveway flatwork. Bundling the apron with a full driveway replacement spreads the mobilization. Whether you go concrete or asphalt for the driveway itself, the apron is commonly concrete for durability at the gutter — see concrete vs. asphalt driveway.
An apron is the heaviest-duty, most regulated part of your driveway. Build it to the city spec with the right permit, make it thicker and reinforced for the traffic it carries, and get the street transition and drainage right so it does not crack at the gutter.
