North Orange County Integrated Regional Water Management Plan (NOC IRWMP) Efforts
Efforts to develop an Integrated Regional Water Management Plan for the NOC WMA began in June, 2007. Stakeholder meetings focused on developing goals and objectives for the region, and began to collect ideas for potential projects to be included in the Plan.
On July 27, 2010 the California Department of Water Resources (DWR) released the final guidelines for the Proposition 84/1E grant program. These guidelines established the general procedures and criteria that DWR is using to implement each Integrated Regional Watershed Management grant program. Based on these guidelines the NOC WMA Plan was restructured to follow DWR Proposition 84/1E guidelines.
The public comment period for the NOC WMA plan closed on January 28, 2011. Comments were received and incorporated in the final plan. The final NOC WMA plan is below, each section of the plan is a separate file for ease of use.
