Oregon City lays out street overlay plan; pavement manager says $1 million needed to stabilize network
Summary
City public works gave a department update on this year's street maintenance: crack sealing and slurry sealing are underway, overlays are concentrated on travel lanes to stretch funds, and the pavement management program estimates about $1 million annually is needed to maintain network condition.
Oregon City public works staff presented an update on the city's 1997 street overlay and pavement-preservation schedule, saying crews have started crack sealing and will begin slurry sealing later this month, with overlays targeted for August where possible.
Leroy Wilson, the city's street supervisor, told the commission that most local streets are asphalt over base rock and show progressive deterioration (cracking, potholes). Given limited funds, staff said crews are prioritizing treatments that extend pavement life at lower cost, including crack sealing, slurry seal (about $0.85 per square yard) and selective overlays (about $4$6 per square yard, depending on milling and use of reinforcing fabric).
Wilson described a cost-saving strategy of grinding and repaving travel lanes rather than overlaying full-width sections on long roads such as Warner Mill; crews plan 24-foot travel-lane resurfacing with fabric underlay to stretch the budget. He warned that these treatments won't look as seamless as full-width overlays and may lead to complaints if edge wear out sooner.
Wilson said the city's pavement management program recommends roughly $1 million per year for maintenance to keep the system from degrading; current funding only allows patching and selective overlays to get through the winter. He explained slurry seal helps preserve the road surface by sealing water out of the base. A targeted slurry sealing schedule was set to begin around the 18th of the month, with overlay dates to be confirmed but aimed for August.
Commissioners asked about specific streets: Warner Parrott to South End Hill had been planned for overlay but will be delayed because sewer work is scheduled that would require future grinding and rebuild; staff will patch in the short term and perform full overlays after sewer work is completed. Commissioners also raised the idea of a local street levy to increase funding; staff said they will explore potential revenue options, including a ballot measure if the city manager and commission direct it.
Why it matters: the update underscores a growing maintenance backlog and a tradeoff between short-term patching and long-term preservation. Staff noted that delaying comprehensive preservation accelerates overall network decline and increases eventual costs.
Next steps: staff will finalize overlay schedules, circulate a list of slurry-seal streets to interested commissioners and residents, and return with revenue options (including potential levy mechanics) if the commission wants to pursue additional funding.
