A performance overview of the Road Commission

Road & Bridge Rating

The Ottawa County Road Commission has implemented an asset management program utilized the PASER road rating process and bi-annual bridge inspections to determine optimal use of funds for roads and bridge system planning and improvement purposes. The PASER rating process and bi-annual bridge inspections are recognized by Federal and State governmental agencies as proper formats to use in determining effective/efficient road and bridge system enhancements.

PASER Condition Rating

PASER (Pavement Surface Evaluation and Rating) is a method of rating roads that utilizes a ten-point scale. It is a visual test of the surface condition of the road. Structural or geometric defects are only considered in that they would be manifested by particular conditions at the surface. In other words, surface condition can suggest certain subsurface defects.

A “Good” PASER rating indicates that a road surface was recently reconstructed or rehabilitated. These roads show very little or no sign of distress and require only routine maintenance such as sweeping and light crack sealing.

A “Fair” PASER rating indicates a road is still structurally sound but the surface is beginning to deteriorate. These roads require preventative maintenance (crack sealing, chip sealing, or overlays).

A “Poor” PASER rating indicates that a road has failed structurally and needs to be rehabilitated or reconstructed.

The goal of asset management is to properly utilize preventative maintenance to prevent roads from deteriorating to a point where they need structural improvement.

Bridge Rating


Bridges are inspected bi-annually and the results submitted to MDOT. A bridge Federal Sufficiency Rating (FSR) is then formulated from the inspection results by MDOT/FHWA.

A “structurally deficient” bridge is restricted to light vehicles, closed to traffic or require rehabilitation. The fact that a bridge is “structurally deficient” does not imply that it is likely to collapse or that it is unsafe. It means that the bridge must be monitored, inspected and maintained. To remain open to traffic, these bridges are often posted with reduced weight limits that restrict the gross weight of vehicles using the bridge.

A “functionally obsolete” bridge is one that was built to standards that are not used today. Functionally obsolete bridges are those that do not have adequate lane widths, shoulder widths, or vertical clearances to serve current traffic demand, or those that may be occasionally flooded.
