Parking Lot Condition Assessment in Wilsonville, Oregon

Quick Verdict

A parking lot condition assessment in Wilsonville is a structured inspection that scores your pavement, maps the failures, and turns a rough-looking lot into a ranked, budgeted repair plan. It documents cracking, potholes, drainage, striping, and ADA issues, then assigns a condition score so you fund repairs in priority order. In Wilsonville, where heavy I-5 corridor traffic and Willamette Valley clay both work against your asphalt, an honest assessment is what keeps you from sealcoating a lot that actually needs base repair. This guide explains what the inspection covers, how to read the report, and how Clackamas County conditions shape the findings.

What the Assessment Measures

A real pavement inspection for Wilsonville commercial property looks at both the surface and the structure, then writes it up so the report holds up for budgeting and for comparing bids.

• Surface distress. Cracking type and severity, potholes, raveling, rutting, and depressions, measured and mapped.
• Drainage. Where water pools after rain, whether grades push runoff to inlets, and whether birdbaths signal a soft base.
• Striping and markings. Faded stalls, worn fire lanes, and arrows that no longer read clearly.
• ADA compliance. Accessible stall count, slopes, access aisles, and signage — the highest-liability items in any lot.
• Structural clues. Alligator cracking, pumping, and edge failure that point to a failing base, not a surface problem.

The result is a condition score plus a distress map. The scoring framework comes straight from our commercial parking lot maintenance plan pillar, which shows how the numbers drive a budget.

Why Wilsonville Conditions Change the Findings

Wilsonville is a Clackamas County hub built around I-5 exit 283, and that location shapes what an assessment finds. The corridor brings heavy commuter and freight traffic, and the industrial parks on the west side see constant truck loading. Wheel-path rutting, entrance-apron fatigue, and load-driven cracking near busy driveways are common findings, and they get weighted heavily because they fail fast.

The other major factor is the ground itself. Wilsonville sits on the valley floor near the Willamette River, where the sub-grade is water-holding clay. Through long wet winters that clay stays saturated, then it dries and shrinks in summer. A good assessment focuses on the lot edges, the low spots, and anywhere downspouts dump onto asphalt, because those are where clay-driven failure starts.

Reading the Assessment Report

A useful report ranks problems so you know what to fund first, not just a list of everything wrong.

Priority	What it means	Typical action
Safety / liability	Trip hazards, ADA gaps, failed fire lane	Fix now
Active failure	Potholes, alligator areas, open cracks	Repair this season
Preventive	Sound surface, aging seal, hairline cracks	Seal and crack-fill on schedule
Monitor	Minor wear, good drainage	Re-inspect next year

If your report is just a number to repave, it is a sales pitch, not an assessment. A proper inspection lets you defer what can wait and act on what cannot. Pair it with a Wilsonville maintenance plan so the findings turn into scheduled action.

How Often to Assess a Wilsonville Lot

Most Wilsonville commercial and HOA lots benefit from a formal assessment every two to three years, with a quick visual check each spring after the wet season. High-traffic retail near the Town Center and any lot already showing alligator cracking should be assessed annually so failures are caught before they spread.

What an Assessment Costs

Assessment pricing depends on lot size, how much measurement and documentation you want, and whether you need a full distress map or a walk-and-rank summary.

Industry Baseline Range: a professional condition assessment for a typical Wilsonville commercial lot runs in the range of $300 to $1,200+, with larger multi-building or industrial sites costing more. These are industry baseline ranges for planning only — actual pricing depends on lot size, access, condition, and current market conditions. Get a site-specific quote.

Current Market Reality

Many reputable contractors credit or waive the assessment fee when you award them the work. In Clackamas County, timing is the bigger lever: Oregon's short May-to-October season fills crew calendars fast, so a late-winter assessment lets you schedule repairs before the season books out. A "free" assessment that exists only to sell you a repave is usually the most expensive option over five years.
