On September 23, 2008 the IID Board of Directors adopted a strategic plan tasking the Water Department to develop an Integrated Water Resources Management Plan (IWRMP, IID Plan) to assist in meeting future water resource demands. On September 29, 2009, the IID board accepted the findings of the draft IWRMP (draft IID Plan) and authorized development of the Imperial Integrated Regional Water Management Plan (Imperial IRWMP) to further these efforts and to assist regional water planning efforts through a process conforming to California Department of Water Resources guidelines.
The Water Department prepared documentation, Imperial IRWMP Regional Acceptance Process (RAP, April 2009), that defined boundaries for the Imperial Region and identified how the region met CDWR guidelines. The Chairman of the Imperial County Board of Supervisors and the President of the IID Board of Directors signed the April 28, 2009 cover letter submitting the RAP to CDWR. Upon review, CDWR approved the Imperial Region for the purposes of preparing an IRWMP and applying for a Proposition 84 Planning Grant. IID subsequently applied for and in 2011 was awarded a Proposition 84 IRWM Planning Grant.
The Water Forum: On June 24, 2010, IID and the County convened a Water Forum comprised of IID, Imperial County and Imperial Region cities and other stakeholders. The Water Forum undertook an extensive process to develop the Imperial IRWMP, with stakeholders reviewing regional conditions and requirements as well as methods for water supply augmentation including water storage and banking, recycling of municipal wastewater, and desalination of brackish water. Water storage and banking have the potential to benefit both agricultural and non-agricultural users, while other IID and municipal capital projects would be implemented primarily to meet requirements for new non-agricultural projects that have a demand higher than was previously delivered to the development footprint.
In November 2012, the Imperial County Board of Supervisors adopted the IRWMP, and in December 2012, the City of Imperial City Council and the IID Board adopted the plan (IID Resolution 43-2012). Adoption by IID, the County and the City of Imperial meets the basic requirement of CDWR for an IRWM plan. The Water Forum authorized the City of Imperial to serve as the Proposition 84 grant administrator.
Until the IID board selects and implements such capital development projects, IID provides water to new non-agricultural projects under the terms of the Equitable Distribution Plan and the Interim Water Supply Policy for Non-Agricultural Projects which is incorporated into the 2012 Imperial IRWMP by reference.
