About IRWM

The California Department of Water Resources (DWR) has a variety of guidelines that cover IRWM and the preparation of Integrated Regional Water Management Plans (IRWMP). These guidelines show what DWR wants to see in each document and also what the contents of a funding application for projects must include.

What is an IRWMP?

According to the California Department of Water Resources, an Integrated Regional Water Management Plan (IRMWP) is a comprehensive planning document to encourage development of voluntary regional strategies for management of water resources.
An IRWMP investigates a broad spectrum of water resource management strategies, identifies the benefits of integrating water management strategies, and develops priorities for implementing projects and programs. An IRWMP is a comprehensive planning document to encourage regional strategies and cooperative solutions for issues of water quality, water quantity and watershed health. For information on the required Table of Contents for an IRWMP – View the DWR IRWM guidelines.

Region Acceptance

The Region Acceptance Process (RAP) is a component of the Integrated Regional Water Management (IRWM) Program Guidelines and is used to evaluate and accept an IRWM region into the IRWM grant program. The RAP is not a grant funding application; however, acceptance of the composition of an IRWM region into the IRWM grant program is required for DWR IRWM grant funding eligibility.

In September 2008, SB1 was signed by Governor Schwarzenegger. SB1 contains the “Integrated Regional Water Management Planning Act”. The IRWM Planning Act provides a general definition of an IRWM plan, as well as guidance to DWR as to what IRWM program guidelines must contain.

CWC Sec 10541(f) states that the guidelines shall include standards for identifying a region for the purposes of developing or modifying an IRWM plan.

At a minimum, a region is defined as a contiguous geographic area encompassing the service areas of multiple local agencies; is defined to maximize the opportunities to integrate water management activities; and effectively integrates water management programs and projects within a hydrologic region defined in the California Water Plan, the Regional Water Quality Control Board (RWQCB) region, or subdivision or other region specifically identified by DWR (Public Resource Code Sec 75026.(b)(1)).
