Five-Year Update of the Westside IRWM Plan

The original Westside Sacramento IRWM Plan (2013) was based on the guidelines and requirements that came from the Department of Water Resources (DWR) in 2012. Since then, AB 1249 and SB 985 brought about new requirements, the 2013 update of the California Water Plan was released, and there was new guidance on how Native American Tribes will participate in IRWM. The Westside Plan needed to comply with all of these new requirements in order to qualify for Proposition 1 grant funds. AB 1249 addressed new water quality standards for nitrate, arsenic and perchlorate (hexavalent chromium). SB 985 required the incorporation of Stormwater Resources Plans.

The Westside Sacramento Integrated Regional Water Management Plan Update 2019 is now complete and was approved by the Regional Water Management Group on January 9th 2019. The plan must clear a detailed review by staff at DWR for the Region to be eligible for Prop 1 grant funds. The updated plan will be submitted to DWR for review in early March, 2019.
