How are the streets selected for the Citys Annual Asphalt Paving Program?
The Engineering Department has an independent consultant conduct a field survey to determine the condition of the streets within the City of Marietta, Ohio. Data collected from this survey is entered and analyzed by a computer program called Micro PAVER. Micro PAVER then assigns each street a numerical Pavement Condition Index (PCI) rating based on the type, severity and quantity of defects of the individual street. The Engineering Department uses the rankings assigned by Micro PAVER to develop the annual road program. After the streets have been selected, the Wastewater Treatment Plant examines the sanitary and storm sewers to determine whether any repairs or improvements are necessary. The Water Treatment Distribution personnel then evaluates the water mains under the selected streets based upon their repair history and capacity to determine whether any replacement or repair work is necessary.
