Overview

In 2002, SAWPA determined to develop a multi-phased planning process called the Integrated Watershed Plan (IWP). This Plan has 3 components, the SARI Planning Study, the Integrated Water Resources Plan, and the Environmental & Wetlands Component.  This Plan is closely related to the Southern California Integrated Watershed Program (SCIWP); click here to get more information on the SCIWP.

UPDATED! The IWP has been updated (as an Integrated Water Resources Management Plan, an IWRMP)

IWP 2005 Update

The 2005 IWP Update was prepared by SAWPA and adopted by the SAWPA commission in June, 2005. This document provides updates to projects that are important to successfully continuing the Integrated Watershed Program in the Santa Ana River Watershed.

SARI Planning Study

SAWPA owns capacity rights, or owns outright, approximately 93 miles of pipeline known as the Santa Ana Regional Interceptor (SARI) Line.  Construction on this pipeline began in the 1970's, and has had several additions up through the year 2001.  This planning study reviews the use of the line, maintenance, costs, and provides recommendations for future actions.

Water Resources Plan

The Water Resources Plan was first written in 1998 to provide the a watershed-wide evaluation of water supply needs and plans for projects that would support meeting these needs. This activity is designed to update the 1998 Water Resources Plan to optimize the use of all water resources in the Santa Ana River watershed, integrate the watershed planning effort with Metropolitan Water Districts Integrated Resources Plan Update and provide descriptions of future projects within the Santa Ana River watershed. The current SAWPA Water Resources Plan was initiated in fiscal year (FY) 1994-1995 and was completed in FY 1997-1998.  The benefits of this project was the development of a single document that combines the demands and available resources for all the member agencies to help resolve anticipated future shortages in the watershed. It is necessary that the information be updated to assure current regional planning alternatives using the latest data possible. The document was designed to:

• Gather existing and projected water demand and supply data from member districts

• Determine potential local and regional projects to optimize available water resources

• Integrate watershed planning with Metropolitan Water District Integrated Resources Plan Update

• Provide descriptions of future local and regional projects Participate in and support Santa Ana River Dischargers Association

• Compile information into a single document.

The Plan was based on 2000-2001 population, water demand, and water supply information as the project baseline, and then developed planning horizons of 2025 and 2050.

Environmental & Wetlands Component

The purpose of the Environment and Wetlands Component of the IWP is to provide a framework for the integration and coordination of future environmental enhancement planning efforts and partnerships within the watershed with the intent of restoring the ecological functions of systems, where possible.

To this extent, SAWPA contracted to prepare this study, which was a snapshot in time (2002) of the current state of the watershed by providing an inventory of resources and opportunities identified by the Plan's outreach activities.
