Action Requested: 
Approve and establish County policy for minimum road and bridge system condition levels per the requirement of 
the Governmental Accounting Standards Board Statement No. 34 using the modified approach of accounting. 
Road system — 90% of lane-miles with Pavement Condition Rating (PCR)>=70 and no more than 5% of lane-miles 
with PCR<55 
Bridge system — 90% of bridges with >=70 sufficiency and no more than 3% of bridges with <50 sufficiency 
Complete description of action requested: 
The Department of Transportation is required to comply with the Governmental Accounting Standards Board 
Statement No. 34 for reporting infrastructure assets (i.e. roads, bridges, etc.). The Department of Transportation 
elected to use the modified approach, which means infrastructure assets will not be depreciated as long as two 
requirements are met. First, the government manages the infrastructure assets using an asset management system. 
Second, the government documents that the infrastructure assets are being preserved approximately at (or above) a 
condition level established and disclosed by the Board of Supervisors. The condition levels established by the 
Board of Supervisors will be reported annually in the County's Comprehensive Annual Financial Report (CAFR). 
This agenda establishes the policy for minimum condition levels to be disclosed annually in the CAFR. 
The condition of road pavement is measured using the MCDOT Road Management System (RMS), which is based 
on weighted averages of nine distress factors of the pavement surface. The RMS system uses a measurement scale 
to evaluate the Pavement Condition Rating (PCR) ranging from zero for a failed pavement to 100 for a pavement in 
perfect condition. The PCR index is used to classify roads in good or better condition (70-100) fair condition (55 - 
69), and substandard condition (less than 55). It is the MCDOT's policy to maintain at least 90% of the roadways at 
a good or better condition level. No more than 5% should be in a substandard condition. Pavement condition 
assessments are determined annually for arterial roads and every other year for local roads. 
The condition of the County's bridges is determined using the MCDOT bridge inspection program that follows 
federal mandates and regulations. The bridge sufficiency rating, which is a weighted average of an assessment of 
the ability of individual components to meet necessary performance requirements, uses a numerical condition scale 
ranging from 0 to 100. All bridges are inspected every two years. 
The Department of Transportation is in compliance with these condition ratings and no additional funding will be 
required to maintain the current condition rating. 
PERFORMANCE INFORMATION: 
Program: Operate & Maintain Transportation Systems Program 
Activity: Roadway Maintenance 
Performance Measure: % of arterial road mileage with pavement condition rating of >=70, % of bridges with 
sufficiency ratings >=70 
Anticipated Results: Road system — 90% of lane-miles with Pavement Condition Rating (PCR) >=70 and no more 
than 5% of lane-miles with PCR<55 Bridge system —90% of bridges with >=70 sufficiency and no more than 3% 
of bridges with <50 sufficiency.
