The Streets Division works under an annual maintenance schedule. This schedule identifies when certain tasks are performed during the year. Examples are vegetation spraying and mowing along right-of-ways occurs between February and April, ditch cleaning and storm drain inspection and cleaning occur during the months of September and October. Street re-marking and patch paving to permanently repair excavations occurring in the winter begin in late spring and progress through the summer months. Other tasks like street sweeping are performed year round.
