City of Nogales General Plan Water Resources Element The City of Nogales is located within the Santa Cruz Active Management Area (AMA), with Nogales and Rio Rico as the two biggest water users in the municipal sector. With growth rates of 5 to 8 percent per year over the last 10 years, creative water management policies will be needed to maintain the AMA goals and meet new water needs if these growth rates continue in the future. In addition, greater development pressure may be coming from the north. Green Valley, located at the northern boundary of the Santa Cruz AMA, continues to experience tremendous growth. The Santa Cruz AMA crosses international borders into Mexico, requiring bi-national coordination of water management efforts. The Santa Cruz River is one of the main water supply sources for Nogales, Arizona and Nogales, Sonora. As such, the water management policies of Nogales, Sonora, with respect to the use of the Santa Cruz River, may have a direct impact on the volume of water entering the Santa Cruz AMA. Arizona Revised Statutes (ARS 9-461.05.C1) requires a water resources element that describes available water supplies and adequacy to meet current and future needs or that includes a plan to meet future water needs. The General Plan Background and Current Conditions Volume identifies available water supplies to meet current demands. This element of the General Plan provides the policy direction to meet future water needs.
Implementation Measures: a) Periodically update the City of Nogales Water Master Plan to ensure that safe and adequate drinking water supply demands are met. b) Require the use of water conservation features, methods and techniques in the design and construction of all new public and private development projects. c) Develop programs to promote the use of drought-tolerant plants, water harvesting and drip-irrigation as a component of the landscaped environment for streetscapes and landscaped areas on all new public and private development projects. d) Develop programs to reduce water consumption for new projects that have a high-water use requirement. e) Locate and develop additional sources of groundwater for potable and non-potable needs as necessary. Goal 2:
