Council adoption of the updated 2024 IWMP will be requested at a future Council meeting. (Barbara Chappell, Water Services Director)

FISCAL IMPACT

The updated 2024 IWMP identifies infrastructure needs and will be used to inform future Capital Improvement Programs, Development Impact Fee Programs, and water/wastewater fees/rate studies. These future infrastructure investments will be brought before Council for action at the appropriate time.

BACKGROUND AND PREVIOUS ACTIONS

On November 13, 2023 (AI-1649), Council adopted Resolution No. 2023-2363 ADOPTING THE CITY OF GOODYEAR FY2025-2027 STRATEGIC PLAN. In the adopted Strategic Plan under the Infrastructure Focus Area, the Water Services Department (Water Services) has a Water and Wastewater Analysis action item to review the current condition and future needs of the water and wastewater systems, which is to be completed in FY2025. The Water and Wastewater Analysis action item is included in the updated FY2025-2028 Strategic Plan, which Council adopted at its November 18, 2024 meeting through Resolution No. 2024-2434 ADOPTING THE CITY OF GOODYEAR FY2025-2028 STRATEGIC PLAN. The IWMP is essential to continue to meet or exceed industry standards for water and sewer services, while planning and expanding Water Services’ systems for anticipated growth. The IWMP is a dynamic master planning process for municipal water and wastewater services that accounts for current population, while also predicting future economic development, residential growth and redevelopment activities. Additionally, the City’s planning processes must also account for water resource availability, drought management and new water quality regulations. The updated 2024 IWMP is a comprehensive study that was completed by Carollo Engineering (Consultant).  The Consultant’s scope of services also included working with Water Services staff on the application to the Arizona Department of Water Resources (ADWR) to modify Goodyear’s Designation of Assured Water Supply (DAWS). For a city growing as rapidly as Goodyear and with the ever-changing landscape of water resources in Arizona, the IWMP should be updated every five years to provide critical information for our capital and infrastructure improvement plans, to help guide our city’s growth strategies, and to formulate our service rates and development impact fees.

STAFF ANALYSIS

The updated 2024 IWMP analyzed in significant detail the current condition of our water and wastewater systems, as well as formulating 5-year and 10-year planning horizons.  The updated 2024 IWMP also reviewed the City’s build-out plans for our service area, but in less detail.  Since the growth Goodyear has experienced since the 2016 IWMP far exceeded its predictions, Water Services staff spent a significant amount of time with the Consultant analyzing current service levels and system needs. The updated 2024 IWMP effort also utilized the City’s recently adopted Goodyear General Plan 2035 in coordination with some of the City’s larger developers in order to identify the needs to support anticipated growth for the next ten years. There are several important recommendations identified within the updated 2024 IWMP, which include: 1. Water Supply Development Strategies for Rainbow Valley:  Explore ideas for how to provide utility services to support development in the Rainbow Valley area. 2. Expand 157th Water Reclamation Facility by 2030:  Due to the rapid growth, the water reclamation facility located on 157th Avenue needs to be expanded. The expansion project is currently in the design phase, and due to the pace of growth in the City, the construction phase is anticipated to begin once the design work is finished. The expansion is projected to support 10 years of growth for the area. 3. Expand the Surface Water Treatment Facility by 2030: When the surface water treatment facility was constructed, there was a second phase anticipated in the 2035 - 2040 time frame. Due to the rapid growth the City has been experiencing, it is anticipated that this facility will need to be expanded in 2030. This project will expand the capacity of the facility from 8 million gallons per day (mgd) to 16 mgd. An Executive Summary of the 2024 IWMP is included as Attachment A.
