A parking lot maintenance plan in Sherwood is a written, multi-year schedule that keeps your asphalt healthy with small, planned work instead of large, surprise repairs. It starts with a condition assessment, then lays out crack sealing, sealcoating, striping, and targeted repairs on a calendar tied to Oregon's May-to-October paving window. For Sherwood property managers overseeing the city's mix of newer retail and older Old Town lots, a plan protects new pavement and rescues aging pavement before it slides into a repave. This guide shows how to build a phased plan for Washington County's Tualatin Valley clay and Oregon's short paving season.
Most failed Sherwood lots were maintained one emergency at a time, with no schedule — the most expensive way to own asphalt. By the time a problem is visible, the cheap fixes are gone.
A maintenance plan changes the timing. Instead of paying for a pothole after it forms, you seal the crack that would have become it. The work is smaller, cheaper, and predictable, which means you can budget for it. Our commercial parking lot maintenance plan pillar explains the lifecycle logic, and it applies directly to Sherwood's range of lot ages.
A plan starts with knowing where you stand. A Sherwood condition assessment gives you the condition score and ranked repair list the plan is built around. From there, the recurring work settles into a predictable rhythm.
| Task | Typical frequency | Why it matters here |
|---|---|---|
| Crack sealing | Every 1–2 years | Keeps winter water out of Tualatin Valley clay |
| Sealcoating | Every 2–4 years | Slows oxidation and protects newer surfaces |
| Striping refresh | Every 1–3 years | Keeps stalls, fire lanes, and ADA markings legible |
| Drainage cleanout | Annually | Prevents standing water over a soft base |
| Targeted patching | As needed | Stops small failures from spreading |
Sherwood's low valley setting near the Tualatin River means the sub-grade is water-holding clay that stays saturated through long wet winters. That clay is why crack sealing leads the plan — keeping water out of the sub-grade is the highest-return maintenance dollar you can spend here. For Sherwood's many newer lots, the plan's job is mostly preventive: start sealing cracks the first season they appear, so the clay below never gets its chance.
Sequencing follows the seasons. Schedule crack sealing in late summer or early fall, ahead of the rains. Put sealcoating and striping in the warm, dry stretch from May through October, when temperatures let materials cure. Drainage cleanouts belong before winter so water moves off the lot instead of soaking the clay.
A plan only helps if it lives on a calendar. A simple phased approach for most Sherwood properties:
This spreads cost evenly and avoids the every-decade sticker shock of a full repave. For property manager paving in Sherwood, predictable annual spending is far easier to get approved than a single large capital request.
Plan cost depends on lot size, condition, and how much repair the first year needs to reach a maintainable baseline — newer lots usually need little catch-up, older ones more.
Industry Baseline Range: ongoing annual parking lot maintenance for a typical Sherwood commercial lot tends to run in the range of $0.15 to $0.50+ per square foot per year once the lot is in good shape, with newer lots at the low end. 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.
Asphalt prices move with the index, and crews serving Washington County fill their calendars as the short season fills. Locking in your plan over the winter usually gets better scheduling and pricing. For Sherwood's newer lots, the cheapest plan is the one you start early — a lot maintained from year one almost never needs the costly catch-up that a neglected lot eventually demands.
A maintenance plan turns guesswork into a schedule and a defendable budget, whether your lot is new or established. Cojo builds and runs asphalt maintenance services for Sherwood properties and across the Tualatin Valley, tied to a condition score so the spending is justified.
