Guidelines

In 2007, a new Water Conservation Ordinance was accepted by the City Council. The first conservation ordinance was established by the City in 2004. That ordinance has since evolved into the 2007 ordinance, with two major amendments:

  1. Declared Outdoor Season: The allowed dates of the Outdoor Irrigation Season will vary each year and will be dependent on the current year's climate. Visit this website each year to find out during which months you are allowed to irrigate; the date will be online by May 1st of each year. Outdoor irrigation shall be prohibited at all times not within the declared Outdoor Irrigation Season. For new landscaping, apply for a variance with the Public Works Department:  Variance Application
  2. Prohibits the Watering of Impervious Surfaces: Examples of impervious surfaces include gravel, asphalt, concrete, brick, or a combination thereof. Make sure your sprinkler heads are not spraying into the sidewalk or street. For help with getting your system running efficiently, contact us for a free irrigation audit or take a look at some lawn watering tips.

This can be a little confusing, so hopefully the chart above can help to clarify when you can and cannot water. The City offers a variety of hardware and tips to help you with your efficient landscape goals as well as some more information for our irrigation professionals.
