"People are staying home," said Doug Nurse, Johns Creek's communications manager, explaining why no weather-related incidents had been responded to as of 1 p.m. Tuesday since the start of the winter blast. He also gave credit to the city's Public Works Department, whose staff are working 12-hour shifts salting and sanding key points and major thoroughfares.

"We brought out a couple of road graders today, and they seem to be working to good effect," said Nurse, who was stationed in the city's Emergency Operations Center.

He said city officials are concerned that residents will start to get cabin fever or run out of supplies and venture out as temperatures drop and ice begins forming again. But so far, "people are heeding the warnings."

Nurse said the city is not able to go into residential neighborhoods to take care of those streets since it has limited resources. "We have to triage," he explained, adding that the city also has to address area state roads as the Georgia DOT is limited in its ability to get out here as it tends to widespread interstate roadway problems.

The city reported on its website that crews had spread 175 tons of de-icing and traction mixture by Monday afternoon. Mechanics are on duty to keep city trucks working, while police and fire vehicles are outfitted with snow-chains and salt and sand. Emergency vehicles are also carrying chainsaws to remove downed trees.

"We're really proud of our guys," said Public Works Director Ken Hildebrandt in a news release. "They have worked heroically to make sure people can get around if they have to."

A decision on whether to open city offices and courts, which have been closed since Monday, had not been made by early Tuesday afternoon. But, "we have to open sometime," Nurse said.
