Residents may now water lawns between 10 a.m. and 6 p.m. on assigned watering days. Each year, time-of-day watering restrictions are scheduled to ease between Nov. 1 and April 1 so that residents may water during what is typically the warmest time of the day. It is important to avoid irrigating when temperatures approach the freezing mark, which often occurs at night.
While time-of-day restrictions provide guidelines that optimize irrigation, it is important to know that lawns (dormant turf grass) do not require any irrigation during cooler months. Shrubs and trees need water only every 4 to 6 weeks. Irrigation systems should be turned off completely and operated manually only if there is no precipitation for more than four weeks.
Designated watering days are assigned based on street addresses as follows: odd addresses irrigate on Sunday and Wednesday; even addresses water on Tuesday and Saturday. Watering is always prohibited on Monday, Thursday and Friday.
