Enforcement of the State Water Resource Control Board’s regulations will be handled by California American Water Company effective July 14, 2015. The overall intent of the California American Waters enforcement program is education and voluntary compliance. Since gaining approval for the program from the CPUC on June 9, 2015, the Utility has notified its customers with a summary of the new provisions via direct mail, email, information on the company website and direct phone calls.

There maybe some cases however where a property owner does not voluntarily comply. This is a summary of the how those cases will be handled:

Enforcement is complaint driven or based on field observations by City or Cal American staff. Residents will be directed to contact California American Water with these observations. Cal Am prefers education over enforcement.

  • First time violators will receive a written warning.
    Second offense of same restriction within 1 year will result in another written violation.
    Third offense of the same restriction within 1 year will result in disconnection of water service for a minimum of 24 hours.
    Additional offenses for separate water use restrictions will start at the beginning step.

Private Property Landscaping

The City of Duarte through its Code Compliance Division enforces City laws relating to maintenance of landscaping throughout the City. However, in light of the ongoing drought and the City’s initiation of significant water conservation measures in order to meet its 28% reduction goal, landscape enforcement must be looked at in a corresponding light. As previously discussed, under Stage 1 voluntary measures, landscape irrigation will be limited to three days per week. Depending on weather, this amount of watering may not be enough to maintain many types of live landscaping, particularly lawns.

Under existing Municipal Codes, dried or dead landscaping including brown lawns are considered a public nuisance and could be pursued as a violation upon a complaint being filed with the City’s Code Compliance Division. As deteriorating landscape conditions become more of a common occurrence under the water conservation measures, staff believes a stay on enforcement of certain landscape related violations should be implemented. Based on staff’s evaluation, regarding the impacts that the proposed water conservation measures will have on existing landscape, the following enforcement practices will be followed during the water shortage:

Code Compliance will discontinue enforcement for the following:

Dead or brown vegetation that is otherwise well maintained, even if shown on an approved landscape plan;

Code Compliance will continue regular enforcement of the following:

Dead, overgrown or neglected landscape that creates a public safety hazard (excessive weeds, excessive dead/unmaintained plantings, etc.)
Landscaping installed as part of an approved landscape plan that is needed to support stability of a manufactured slope area.

At such time, the enhanced Statewide Water Conservation measures are lessened or eliminated, Code Compliance staff will resume enforcement of the regulations as originally adopted and intended in the Municipal Code.
