As the Department of Public Works continues to keep City property clear of obstructions and its lawns and gardens trimmed, the Parks & Greenery Department asks for residents help in keeping sidewalks and roadway sight lines clear.

This means keeping hedges bordering sidewalks and plants that might obstruct visibility at driveway and road intersections trimmed back.
