Contact: Mark Modin Phone: 506-8644 Continued fron Return to: Helen Ortiz-Silva Phone: 506-4108 Location: DEPT OF TRANSPORTATION Procurement/Distribution Action Requested: Amend action taken place on June 10, 2002 (C-64-02-262-5-00) to establish County policy 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 — 85% 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 5% of lane- miles with PCR<55. Complete description of action requested: The Department is using a new method to measure pavement condition. This method is more accurate. 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 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 85% 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. https://ac.marieopa.gov:8889/COB review item.asp?ai num=C-64-02-262-5-01&pools... 3/30/2005 Routing: Meeting Date: 0 4 1 0 6 1 2 0 0 Legend X=Pending A=Approved R=Rejected CNTY_ENGR LEGAL OMB COB Review item Page 2 of 2 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: °A of arterial road mileage with pavement condition rating of >=70, °A) of bridges with sufficiency ratings >=70 Anticipated Results: Road system — 85% 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.
