​​​​​​GOV​-05

Improve Water Efficiency

Measu​re

With this measure, the County will reduce its water consumption by improving efficiency and using low-flow fixtures in County buildings and facilities and using recycled water for outdoor activities. The County will also develop three demonstration projects to promote native vegetation and high-efficiency irrigation techniques to lead by example and inspire the community.

This measure has no incremental GHG reductions because it reduces the County government’s electricity usage, and it is assumed that by 2030 emissions from electricity will be zero due to GHG-03: Support SMUD in the implementation of the 2030 Zero Carbon Plan. However, there may be some reduction in GHG emissions outside of the government operations GHG inventory boundary, such as reduced energy consumption for upstream water conveyance and wastewater treatment.

​Ac​​tions

Action GOV-05-a: Develop and adopt a County Buildings and Facilities Water Efficiency Plan to achieve a goal of 11 percent reduction in potable water usage below 2021 levels for all County buildings by 2030 and 29 percent by 2045. The plan should include:

  • ​a review of County building and facility water consumption,
  • water efficiency upgrade opportunities, and
  • a cost and timeline for performing upgrades.

Status: Not Started 


Action GOV-05-b: Continue to replace water fixtures with low-flow equivalents to have all County buildings and facilities using low-flow equipment by 2030.

Action GOV-05-c: Continue to use recycled water for landscaping as per the General Waste Discharge Requirements for Landscaping Irrigation Uses of Municipal Recycled Water (SWRCB Order no. 2009-0006-DWQ). Status: Not Started 


Action GOV-05-d: Conduct a landscape conditions and irrigation audit to evaluate irrigation practices around County facilities to:

  • Identify essential and non-essential/non-functional turf.
  • Remove non-essential turf by 2027 and replace it with native and drought-tolerant species, consistent with AB 1572 requirements for removing non-functional turf.
  • Modify irrigation practices and equipment accordingly for essential turf (e.g., timers, sprinkler heads).
  • Evaluate necessary changes in irrigation practices for dry years to ensure tree survival.

Status: Not Started 


Action GOV-05-e: Create drought-tolerant demonstration projects with interpretive signs at the three most visited County buildings to exhibit and promote native vegetation and high-efficiency irrigation techniques. Status: Not Started 


Action GOV-05-f: Develop a list of drought tolerant plants for use in County landscaping projects which focuses on California native plants and considers ability to support local pollinators and wildlife, plant size, sun and shade needs, water use, and wildlife benefits. Status: Complete

​Status of Implementa​​​tion

The Department of General Services has completed an administrative draft Green Building Policy which is being peer reviewed by County departments. The County complies with Building Code requirements for water efficiency fixtures for new construction and upgrades existing fixtures upon replacement. Challenges exist with older facilities built to older code standards when utilizing low-flow fixtures. The Department of General Services is identifying old and inefficient equipment for future retrofits to increase water saving capabilities. More work is needed to identify funding and responsible parties to conduct audits and benchmarking. County staff are exploring State and federal planning grant opportunities to support this measure.
