Angus Mordant, Bloomberg via Getty Images Casper residents can now use the new "Casper 311," the online and mobile app for requesting snow removal, according to a prepared statement from the city manager's office. “Yesterday, we let citizens know they can call us to put their street on the list for snow removal," Streets and Traffic Manager Shad Rodgers said. "Today, we added snow removal to the app for citizen convenience,” Rodgers said. The app is available 24 hours a day and not subject to phone line availability. Every residential street needs snow removal after the storm this past weekend that dumped more than 2 feet on the area and made roads impassible and shut down schools, businesses and government offices.
