With a chance of snow showers predicted for this weekend, City Hall leaders are reminding Lawrence residents to dust off their snow shovels.

City officials are warning Lawrence residents that the city’s snow shoveling ordinance is in force. Among the details of the ordinance:

• Property owners are required to clear public sidewalks adjacent to their property of snow and ice within 48 hours of a winter storm.

• The city measures the 48-hour period from the time snow stops falling during a storm.

• Shoveling is the preferred method to clear a sidewalk, but the ordinance does make provisions for people to spread sand on icy areas that are difficult to clear.

The city won’t necessarily act as snow shoveling cops by driving through neighborhoods looking for violations. Instead, they’ll respond to complaints from residents. But city inspectors previously have issued tickets to neighboring properties where a complaint has been filed.

People can call in a complaint at 832-7700 or they can submit one online at lawrenceks.org/pds/code_violation.

Fines of $20 per day can be assessed for violating the ordinance, plus violators must pay Municipal Court costs of $52.

Last year, the ordinance — when the city was hit with 43 inches of snow — created a stir. The city issued more than 700 tickets during the season, said Megan Gilliland, the city’s director of communications.

City leaders also are reminding people that the snow shoveling ordinance creates a need for volunteers for the Safe Winter Walkways Program. The program signs up healthy individuals to shovel sidewalks for the elderly and others who can not do so on their own. People can sign up to volunteer for the program at lawrenceks.org/safe_winter_walkways.
