The Santa Cruz Integrated Regional Water Management (IRWM) program provides a framework for local stakeholders to manage this region’s water and water-related resources. The Santa Cruz IRWM Plan was developed in response to California’s IRWM planning initiative to promote an informed, locally-driven, and consensus-based approach to water resources management.

The IRWM Plan includes strategies for developing and implementing policies and projects to ensure sustainable water use, reliable water supply, better water quality, improved flood protection and stormwater management, and environmental stewardship.  Find out more

IRWM Plan 2014
The County of Santa Cruz in collaboration with the local agencies, stakeholders and in partnership with the Regional Water Management Foundation (RWMF) completed the IRWM Plan in 2014.  This work was funded in part through a competitive grant awarded by the Department of Water Resources and with local agency funds.  The Plan is available here: IRWM Plan 2014.

IRWM Plan Addendum 2019 
An addendum to the IRWM Plan was completed in 2019 to update and expand content in the Plan to meet the state's IRWM Plan Standards, including new information on water quality and climate change vulnerabilities.
