Primarily, the City contracts with a private contractor to perform basic weekly, monthly and annual landscape work that includes the mowing of grass, the trimming shrubs and trees, the cutting back of brush from adjacent open space for fire safety, and the clearing of leaves and other debris and trash from drainage ditches (V-ditches) to prevent erosion and flooding. Some areas are also irrigated or hand-watered. In District No. 39, there are five (5) mini-parks that are also maintained. In all, work funded by assessments is aimed at keeping the neighborhoods attractive, reducing erosion, and limiting dangers from wildfires.
