Polk County outlines road projects, chip-seal cycle and culvert priorities

Polk County commissioners on Feb. 17 heard a detailed update from public works staff on road preservation, culvert and bridge priorities and equipment needs.

Public works presenter Todd Whitaker said the county completed an initial chip-seal cycle and is launching a second round rather than placing a new road bond immediately. “We’ve gone through and we’ve covered everything with chip seal once. Now we’re starting on the second round, which we’ve never really been in a position to do before,” Whitaker said, describing planned patch paving, crack sealing and smaller overlays.

Whitaker identified targeted projects including a roughly one-mile overlay on Enterprise Road to address longitudinal cracking and settlement and repairs on AR Ford in Grand Ronde. He flagged Rogers Road at Highway 51 as an angled intersection that would benefit from a design and possible right-of-way acquisition to improve safety and traffic flow.

The county is evaluating a higher-cost ‘‘high-build’’ striping paint that Whitaker said costs about 2.5 times the regular product but may provide better wet-weather reflectivity and longer life; if adopted, the county may alternate centerline striping on a multi-year schedule to balance costs.

On drainage: Whitaker said crews identified several failing culverts, including large culverts on Gage Road that function as fish barriers and are categorized as bridges. The county plans to submit an application for COBRA replacement funding through remaining grant rounds to replace three of those culverts, and described a 10-year planning horizon to address other culverts.

Whitaker also reported that the county’s bridge master plan, prepared by David Evans and Associates, is nearly complete and has been extended to include additional cost and budget analysis. He said the consultant’s work is expected to be delivered in April after a one-month extension to add budget details.

Staff are soliciting proposals for automated pavement-inspection technology (PCI, crack mapping and rut mapping) and are weighing the data-management burden that comes with routine automated data collection. The county is also considering outsourcing traffic counting because its tube-based equipment is aging and insufficient for comprehensive counts.

Other updates included RFQs for spring and fall vegetation-spray programs, procurement planning for a belly-dump and truck chassis, and decisions about replacing gravel trucks to accommodate rural-broadband obstructions. Whitaker said the sheriff’s department’s surveillance trailer is under assessment for repurposing as a traffic-monitoring trailer and that Dean Bender is coordinating the contractor assessment.

Commissioners pressed staff on weight-limited bridges, spray-vendor qualifications, crash history at intersections such as Parker Road and Stapleton/99, and whether counties have comparable road-quality dashboards. Whitaker noted that state reporting requirements (HB 2017) require condition reporting and said the county’s recent pavement condition index (PCI) has been high compared with peers.

What’s next Whitaker said staff will submit the culvert replacement grant application, finish the bridge master plan in April, and return with contract and procurement details as proposals and RFQs proceed. The board adjourned after the update.
