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
