It’s a perfect storm for potholes. And City Council is taking short-term action while continuing to advance longer-term solutions.
To demystify the pothole: water infiltrates under the roadway surface through cracks but doesn’t drain because of our soil conditions. That water expands as it freezes and exerts pressure on the roadway material. This happens over and over, and combined with the pounding of vehicle traffic, you get a pothole.
But the compounding factor is that we are behind on maintenance. Like most cities we are better at building new things than looking after old ones. So we have more cracks and more patchwork than we should.
We are still way behind on arterial (main) road maintenance. Last month Council diverted $13 million more into a ‘mill and fill’ program to get caught up on some of the worst stretches of road. That work will run all summer. We will need to commit more funds in future years too. (more…)
