Driveway Aprons in Oregon: Where Your Driveway Meets the Road

Driveway Aprons: Where Your Driveway Meets the Road

The apron, also called the driveway approach, is the transition between your private driveway and the public road. It is a small piece of pavement, but it carries outsized importance: it sits partly in the public right-of-way, it has to meet government standards, and it takes the most abuse of any part of your driveway as vehicles slow, turn, and cross it. This guide explains permits, standards, material choices, and what to expect when installing or replacing an apron in Oregon. For the full driveway picture, start with our complete asphalt driveway guide.

What the Apron Is and Why It Matters

The apron is the flared section where your driveway connects to the street. It often spans the area between the road edge and your property line, which means part or all of it usually sits in the public right-of-way rather than on your private property. Because of that, the apron is governed by the city, county, or, for state highways, ODOT, not just by you. Its job is to provide a smooth, safe transition for vehicles and to manage how water crosses between the road and your driveway.

Permits and the Right-of-Way

This is the part that catches homeowners off guard. Because the apron sits in the public right-of-way, installing or replacing it almost always requires a permit and must meet the jurisdiction's approach standards. Depending on your location:

• City streets are governed by the city's public works standards
• County roads follow county approach standards
• State highways require an ODOT approach permit

Each sets rules for the apron's width, angle, slope, sight distance, and how it ties into the road and any curb, gutter, or sidewalk. A contractor experienced with local requirements handles this permitting and builds to the approved standard. Skipping the permit can mean fines and being ordered to redo the work.

Standards That Affect the Apron

Approach standards exist for safety and drainage. Common requirements include:

• Width limits for residential approaches
• Sight distance so drivers can see oncoming traffic when exiting
• Slope and grade so vehicles do not scrape and water drains correctly
• Curb cuts and transitions where there is existing curb and gutter
• Drainage continuity so the apron does not block the road's drainage; on rural roads this often ties into a culvert, which our driveway culvert installation guide covers

These standards vary by jurisdiction, which is why local experience matters.

Concrete vs. Asphalt Aprons

Aprons can be built from asphalt or concrete, and some jurisdictions specify which:

• Concrete aprons are common where the standard calls for them, especially in areas with curb and gutter. Concrete handles the turning and stopping stress at the road edge well and is sometimes required.
• Asphalt aprons match an asphalt driveway seamlessly and are often used on rural roads and where the jurisdiction allows. They are typically less expensive and tie cleanly into the driveway surface.

Sometimes the jurisdiction dictates the material; sometimes you choose. A contractor familiar with local rules will tell you what is required or recommended for your road.

Drainage at the Apron

The apron is a critical drainage point. Done wrong, it can dam water against the road or send road runoff up your driveway. Done right, it keeps the road's drainage flowing and channels water away from your property. On rural roads with roadside ditches, the apron typically bridges the ditch with a culvert. In all cases, proper grading at the apron protects both your driveway and the road. Our driveway drainage solutions guide covers the broader picture.

What an Apron Costs

Apron cost depends on size, material, the standards you must meet, and any drainage work like a culvert. Concrete aprons generally cost more than asphalt. Permitting adds time and sometimes fees. Because the apron is small but specialized, its per-square-foot cost can be higher than the open driveway. Industry baseline ranges vary widely with the jurisdiction's requirements, so a site-specific quote is the accurate figure. For the broader driveway pricing, see our asphalt driveway cost guide.
