Property owners are responsible for the cleanliness of the sidewalks next to their buildings--including keeping a path free from snow and ice. The City of St. Louis offers owners a cost sharing option through the 50/50 sidewalk program. If your property is eligible and you agree to participate, the City will split the cost of sidewalk repair with you.
The grassy area between the street curb and the sidewalk is known as the tree lawn space. The City maintains the trees in this space--and will plant new trees as necessary. Mowing, watering and maintaining from the street side to the alley side is the responsibility of the property owner. Grass or weeds must be kept to 6 inches or less; the space must be free of litter and debris.
