ANN ARBOR, Mich. -

Snow-covered sidewalks in Ann Arbor are proving bothersome and hazardous for people trying to use them -- and costly for property owners who allow the snow to pile up.

According to published reports, officers have handed out 438 notices since Dec. 1 to home and business owners for not shoveling snow from sidewalks.

Forty-four people who failed to clear the walks have been ticketed. Fines can reach $500.

The physically disabled are among those who have a difficult time navigating snowy walkways.

Lingering frigid temperatures also have prevented a record January snowfall from melting.
