Asphalt Paving in Mapleton, Oregon: 2026 Cost & Service Guide

Asphalt Paving on the Siuslaw River

Mapleton sits in western Lane County in the Coast Range, on the Siuslaw River along Highway 126, partway between Eugene and the coast at Florence. This is some of the wettest country in Oregon, with heavy coast-range rain, a tidal-influenced lowland along the river, and the damp, salt-tinged air that comes with being close to the coast. Paving here is defined by water. Every driveway and lot has to be built to shed the rain and survive the saturated, sometimes tidal ground that comes with a river-bottom town.

Cojo Excavation & Asphalt paves for Mapleton and the lower Siuslaw from our Willamette Valley base, running west on Highway 126 through the Coast Range. We build to a spec that handles the wet, because nothing else survives a Mapleton winter.

Why Coast-Range Paving Is About Water

Asphalt that lasts in Mapleton is built from the base up with drainage as the first concern. Three local factors shape every job.

• Extreme rainfall — Mapleton sits in one of Oregon's heaviest rain belts. Water that soaks into or pools on pavement is the fastest path to base failure. Aggressive edge drainage and a clean pitch are non-negotiable.
• Tidal-influenced lowland — The river bottom along the Siuslaw can carry a high water table and saturated soils. Building a stable, free-draining base over soft, wet ground takes extra work and is what determines whether the pavement holds.
• Coastal moisture and salt air — The damp, salty air near the coast accelerates surface wear, making sealcoating and good drainage even more important than inland.

The full process and cost drivers are in our asphalt paving cost in Oregon guide.

Industry Baseline Pricing for Asphalt Paving

We will not quote a firm price without seeing the site, and you should be wary of any contractor who does. What we can give you is the industry baseline ranges the national market reports, with the clear caveat that coast-range projects, with their drainage, soft-soil, and haul demands, frequently run above them.

Industry baseline ranges. Actual cost depends on thickness, sub-base, soil, drainage, access, and haul distance to Mapleton.

Scope	Industry Baseline Range
New asphalt driveway	$4–$8 per square foot
Asphalt overlay (resurface)	$2–$5 per square foot
Small commercial lot paving	$3–$7 per square foot
Full removal and replacement	$5–$10 per square foot
Aggregate base prep	$1–$3 per square foot

Mapleton is a haul west through the Coast Range from the valley, so material transport and mobilization factor into every quote, and soft river-bottom soils can demand extra base work. Pairing the paving with any needed site prep in a single mobilization is the most economical approach.

Soft Ground and the River Bottom

The defining challenge of paving in Mapleton is building a stable base over wet, sometimes tidal ground. River-bottom soils can be soft and saturated, and laying asphalt over an inadequate base in that setting is a guaranteed failure. We evaluate the ground first, build up a free-draining aggregate base sufficient for the conditions, and engineer drainage to keep water moving away from the pavement. On the worst lots this means more excavation and base work than a valley job would, and that work is what makes the pavement last instead of sinking and cracking within a season.

Driveway and Small-Commercial Work

Most Mapleton paving is residential driveways and small-commercial pads serving the riverside community and the Highway 126 corridor. Driveways are about durability and drainage on wet, low-lying ground. Commercial work adds traffic load and sometimes striping once the surface is down.

For either, the foundation determines lifespan, more so here than almost anywhere. If your existing driveway is breaking up, our signs your driveway needs repaving guide helps you tell repair from replacement, our driveway repair in Mapleton page covers the middle ground, and our driveway sealcoating in Mapleton guide explains how to protect a surface against coastal moisture.

Permits and the Highway 126 Right-of-Way

Highway 126 is a state route, so work touching its right-of-way, like a new driveway approach onto the highway, can require an ODOT access permit. Lane County thresholds apply for larger site work, and proximity to the Siuslaw can bring additional drainage and erosion considerations. We know the local permitting picture and fold it into the project plan so you are not navigating it alone.

Why Mapleton Property Owners Choose Cojo

Coast-range paving punishes shortcuts harder than almost any inland job, because the water never lets up. We bring valley-grade equipment and an honest read on what your site needs: if the soft river-bottom ground requires more base work and drainage, we say so, because skipping it is how a driveway sinks within a year. The run west on Highway 126 from our base is routine.
