Notice a lag time between when a Buffalo street's topcoat comes off and the finishing touches are applied?
That has to do with several factors, according to Steven Stepniak, the city's public works commissioner, and Mike Finn, city engineer.
The first stage involves milling, in which private contractors remove the top surface. It's the quickest of the two stages.
The work can be done regardless of rain.
The paving process, with a different crew of workers, typically follows three to five working days later.
The work is slower, cannot be done in the rain and is subject to road conditions, including what is below the surface. That can include utility issues – since the majority of utilities are in the street – or unforeseen problems such as a manhole that needs to be adjusted to the curb line.
Street cleaning this summer has a $7 million price tag, Stepniak said.
