Subject
RESOLUTION NO. R20-133
 
A RESOLUTION OF THE COUNCIL OF THE CITY OF GLENDALE, MARICOPA COUNTY, ARIZONA, AUTHORIZING AND DIRECTING THE ENTERING INTO OF AN INTERGOVERNMENTAL AGREEMENT WITH THE CENTRAL ARIZONA WATER CONSERVATION DISTRICT PROVIDING FOR THE STORAGE OF WATER AT THE TONOPAH DESERT RECHARGE PROJECT.
Presented by: Craig Johnson, P.E., Director, Water Services
Purpose and Recommended Action
This is a request for City Council to waive reading beyond the title and adopt a resolution to enter into an Intergovernmental Agreement (IGA) with Central Arizona Water Conservation District (CAWCD) for water storage at the Tonopah Desert Recharge Project.
Background
The City of Glendale holds allocations of Central Arizona Project (CAP) water through its municipal and industrial subcontract and leases.  Glendale plans to store some of its unused CAP water in underground aquifers through the use of recharge basins at designated CAP facilities.  Glendale will accumulate long-term storage credits for the recharged CAP water.  These credits are reserved for future use in the event of drought, shortages, or to meet additional demand.  The stored water credits will eventually be recovered through wells.
 
The Arizona Department of Water Resources (ADWR) granted Glendale water storage permits for CAP water at several facilities throughout the valley.  Depending on the amount of capacity available each year, the permits grant Glendale the ability to store CAP water at any or all of these facilities.  The addition of a water storage permit for the Tonopah Desert Recharge Facility will give Glendale the flexibility to store CAP water at CAP’s largest recharge project. 
Analysis
This intergovernmental agreement (IGA) will allow the City to store a portion of its CAP water at CAWCD’s Tonopah Desert Recharge Project to provide the City with greater flexibility in managing its available water resources.  The City will be able to cost-effectively develop stored water credits with unused portions of its Central Arizona Project and Colorado River water supplies. These stored water credits may be recovered through wells at any time in the future when the City needs additional water.  Having the option to store at several facilities provides Glendale flexibility and redundancy in the operation of its water storage program. 
Previous Related Council Action
On December 18, 2014 Council passed resolution number 4902 and authorized the City Manager to enter into an intergovernmental agreement with CAWCD for water storage at the Superstition Mountains Recharge Project.
 
On December 18, 2014 Council passed resolution number 4903 and authorized the City Manager to enter into an intergovernmental agreement with CAWCD for water storage at the Hieroglyphic Mountains Recharge Project.
 
On December 18, 2014 Council passed resolution number 4904 and authorized the City Manager to enter into an intergovernmental agreement with CAWCD for water storage at the Agua Fria Recharge Project.
Community Benefit/Public Involvement
The IGA allows the City to maximize the use of available supplies by developing stored water credits for water that the City cannot make immediate or direct use of.  These credits will increase the amount of water available to the City and bolster its future designations of assured water supply.
 
Budget and Financial Impacts
There is no budget or financial impact from executing the agreement.  Should Glendale exercise the agreement by storing water, the City will pay the regular per acre-foot (AF) price for CAP municipal and industrial water that it stores ($213 per AF in calendar year 2021).  In addition, CAP charges an underground water storage fee for storing water at its facilities ($13.00 per AF CY21).
