An area like Lake Arrowhead has many tourist attractions and tourists; it also has a lot of snow and ice. Because of all this snow and ice, business owners must make sure their sidewalks and parking lots are clear and safe so pedestrians do not slip and fall.
The Salt Institute, located in Alexandria, Virginia conducted a survey several years ago with county and municipal agencies regarding their sidewalk snow clearing practices. The study showed that 83% of the agencies had policies requiring business owners to remove snow and ice "within 24 hours of the end of the snowstorm." If the business owner did not comply, their penalties would range from a ticket to misdemeanors punishable by up to 90 days in jail and/or fines of up to $500.
Of course, if a pedestrian slipped and fell, the business owner could face a lawsuit alleging negligence. If you have fallen in front of a business that neglected to remove the snow and/or ice from in front of their store, I would suggest you contact an experienced Personal Injury attorney who will know California laws and take the required actions against this business owner on your behalf.
