2013 Resurfacing Plan
The City's 5-year Resurfacing Plan has been adjusted for the 2013 year in an effort to accommodate another capital improvement project. Portions of Chamblee-Dunwoody and Mount Vernon Roads will be deferred until the existing water lines along these streets are replaced. The upgrade of the water utility lines is part of an initiative by DeKalb County and is expected to occur this year.
Since 2009, the City has invested over $5,000,000 in repaving its roads. An additional $2,000,000 has been allocated for 2013. Each year, approximately 70% of the funding is directed towards high traffic volume roads. The remaining 30% is applied to the lowest rated neighborhood streets based on the pavement condition assessment.
How have these streets been prioritized?
In 2009, Public Works completed a pavement condition assessment of all of the public streets within the city.
The assessment serves two primary purposes:
To provide an objective evaluation of the condition of the city’s pavement infrastructure and provide the baseline for future maintenance and management of that infrastructure.
To provide a complete inventory of pavement area by street with replacement costs and remaining service life. This information is being used by the city’s Finance department for asset reporting in the city’s financial reports.
The assessment, conducted by IMS Infrastructure Management Services, consisted of surveys of each roadway segment to measure roughness, rut depth and crack condition. The data collected was used to develop a pavement condition index (PCI) ranging from 0 to 100 for each roadway segment.
The attached overview report summarizes the methodology and provides a list of roads with corresponding PCI numbers.
Significant findings of the report include:
The city has 150 centerline miles of roadway with a replacement cost value of $216 million.
Although the overall condition of the city’s pavement is described as “fair”, the majority of the city’s pavement is at a point where it is beginning to deteriorate at an accelerated rate due to its age and lack of maintenance.
Approximately $2 million per year is needed to maintain the current condition of the overall road system.
Currently, there is a 13% backlog of roads in “poor” condition. Even at a funding level of $2 million per year this backlog will remain and may even grow slightly in the first 5 years of the pavement management program.
