Outdoor Water Conservation

​​ During the dry summer months, outdoor watering often doubles our community's daily average drinking water demand from 10 to 20 million gallons per day. This places an extra strain on the City's drinking water supply. Watering lawns and landscapes accounts for 80-90% of the increase. Nearly half of this water is wasted due to evaporation loss, over-watering and run-off.

For information on collecting rainwater for outdoor use, visit our Rainwater Harvesting page.

Smart Watering

Our climate with moist, mild winters and dry summers allows residents to have a green lawn for most of the year without additional watering. Consider letting your grass go dormant during the summer. Though your lawn will “Go Gold” without added water, it will green up when the rain returns in the fall.

If you choose to water your lawn, remember to follow smart watering recommendations (PDF) and the City’s voluntary outdoor watering schedule (PDF). Signs are seasonally posted to remind residents about the watering schedule.

No Watering

Residents are asked to limit watering to the following schedule to help reduce stress on the City's drinking water supply from June 1 to September 15 annually:

  • Odd numbered street addresses water only on Wednesdays, Fridays, and/or Sundays.
  • Even numbered street addresses  water only on Tuesdays, Thursdays, and/or Saturdays.
  • No outdoor watering on Mondays to allow the City's reservoirs to recharge.

The voluntary watering schedule does not apply to:

  • Drip irrigation systems
  • Handheld watering methods
  • Flower and vegetable gardens
  • Outdoor potted plants and hanging baskets
  • Newly planted lawns

Other lawn watering tips:

  • The average lawn requires only one inch of water per week to stay green. Overwatering doesn’t improve your lawn’s health and results in runoff and water waste. Place a series of shallow containers throughout your lawn. Turn the sprinklers on and water your grass. When you’re finished, measure the water in the dishes. Adjust the time until the water is about one inch deep.
  • Regularly check and adjust your sprinklers. Water only your lawn and not the pavement.
  • In order to reduce the amount of water lost to evaporation, the best time to water your lawn is in the mornings between 7am-10am.
  • Mow your lawn with blades set high; grass that is 2”-3” tall promotes a healthier root system and helps retain soil moisture.
  • Consider replacing lawn with native plants to use less water, fewer chemicals, and eliminate mowing.
