The purpose of this report is to support Integrated Regional Water Management efforts in continuing to integrate and address the needs of DAC and Tribal communities within IRWMs. This report 1) builds upon the 2016 IRWM Plan’s identification of regional priority issues and challenges for DACs; 2) provides community assessments that may be more meaningful than DWR’s single-measure determination of “disadvantaged” status based on income; 3) documents the water and wastewater needs and challenges within the CABY IRWM; 4) documents the technical assistance needs and requests for each IRWM; and 5) provides recommendations for how to benefit DACs and Tribes moving forward.
