It's called "slurry seal," and it's an oil- and water-based treatment. The city expects to spend $200,000 on patching areas in south Richland, like Willowbrook, Steptoe, Hills West and Orchard Hills. It lasts half as long as repaving, but it costs a tenth as much.
"No agencies have the budget to overlay all the streets every 10 to 15 years, it just costs way too much money, so trying to to stretch how long that pavement can last for the limited budget we have," said safety engineer Jeff Peters.
Richland will begin applying the slurry seal next month. Central Richland will get the treatment next year.
