At a recent work session of the Brookhaven City Council, members were updated on the city’s paving plans and projects with a recommendation that the city spend at least $2.5 million a year to maintain repairs.
Public Works Director Bennett White discussed the city’s pavement conditions and maintenance needs at a Feb. 23 meeting.
White explained that the city of Brookhaven has just under 12 miles of arterial roadways
plus an additional 106 miles of collector and residential roadways encompassing over 1.9 million square yards of asphalt surfacing.
“At a replacement cost approaching $750,000 per mile plus the cost of the right of way and improvements, the city has over $88 million invested in their paved roadway network,” he explained in a memo.
White also explained that 16 percent of the streets are rated as good and are candidates for heavy surface treatment rehabilitation, routine maintenance and thin overlays.
Also, 46 percent of the network can be considered marginal or fair … and “if left untreated, they will decline rapidly into reconstruction candidates,” he said.
“These two categories, representing close to one half of the network, are the biggest areas of concern as they require a large influx of rehabilitation capital in a short period of time in order to prevent them from becoming reconstruction candidates,” White stated in the memo.
“Sixteen percent of the network may be considered in poor condition. The remaining 2 percent of the network is rated very poor, meaning these roadways have failed or are past their optimal due point for overlay or surface based rehabilitation.This value is low when compared to than many similar sized agencies and indicates that only a few roadways will require full reconstruction,” he added.
White said the city should adopt a policy statement identifying the desired overall pavement condition rating and acceptable amount of backlog.
“We suggest a target that addresses the long term issue of backlog growth while allowing the overall network PCI [paving condition index) to increase. An annual budget of at least
$2.5 million is required to maintain the backlog at its current level of 17 percent within 10 years. This will result in a PCI increase to just above 65 within five years,” he said.
White also explained that the Brookhaven paved roadway network is broken into three functional classifications: arterials, collectors and local (residential) roadways.
The arterial roadway network consists of 11.6 centerline miles of roadway with an average PCI score of 69. The city has 8.6 miles of collectors with a PCI of 68, while the residential network contains 97.5 miles and has an average PCI score of 58.
