Proposition 1

On November 4, 2014, California voters approved Proposition 1, the Water Quality, Supply, and Infrastructure Improvement Act of 2014. Proposition 1 authorized $510 million in Integrated Regional Water Management (IRWM) funding. Funds are allocated to 12 hydrologic region-based Funding Areas.


The Proposition 1 IRWM Grant Program, administered by DWR, provides funding for projects that help meet the long-term water needs of the state, including:

  • Assisting water infrastructure systems adapt to climate change;
  • Providing incentives throughout each watershed to collaborate in managing the region's water resources and setting regional priorities for water infrastructure; and
  • Improving regional water self-reliance, while reducing reliance on Sacramento-San Joaquin Delta.

The 2016 IRWM Guidelines is comprised of two volumes. Volume 1 contains the general process, procedures, and criteria that DWR will use to implement the Proposition 1 (The Water Quality, Supply, and Infrastructure Improvement Act of 2014) IRWM Grant Program, which includes IRWM Planning, IRWM Implementation, and Disadvantaged Community Involvement Grant Programs. Volume 2 contains the IRWM Plan Standards and related guidance, and the region acceptance and plan review procedures.
