Action Requested: 
Amend action taken place on April 6, 2005 (C-64-02-262-5-01) to establish County aid . j
ic for minimum road and bridge 
system conditon levels per the requirement of the Governmental Accounting Standards Board Statement No. 34 using the 
modified approach of accounting. 
Amend as follows: 
Road system —75% of road-miles with Pavement Condition Rating (PCR)>70 and no more than 5% of road-miles with 
PCR<55. 
Bridge system — 90% of bridges with a >=70 sufficiency rating and no more than 3% of bridges with a <50 sufficiency 
rating. 
Complete description of action requested: 
The Department has acquired new equipment using a triple laser road profiler to measure pavement condition. This method 
is more sensitive and has caused a change to our baseline data over the last 3 years. As a result, we are amending the road 
system rating to conform with the most recent data. 
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 very good or excellent condition (71-100) good condition (55 -70), and fair to 
poor condition (less than 55). 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

Anticipated Results: Road system — 75% 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.
