Conventional wisdom often views the urban water sector as being among the more sensitive sectors in the arid U.S. Southwest. To test this assumption, the Climate Assessment Project for the Southwest analyzed the water budgets of five Arizona cities to determine how severe the impacts would be from the deepest one-, five-, and ten-year droughts on record. Case study sites for the analysis included the Phoenix Active Management Area, Tucson Active Management Area, Santa Cruz Active Management Area, and the Benson and Sierra Vista subwatersheds of the San Pedro River.
This document provides a summary of international, federal, state, and local laws and policies that may facilitate or constrain decision making within the context of climate impacts. The evaluation concludes that Arizona has a reasonably well-developed structure for governing water management in the more stringently managed areas of the state.
Research into the sensitivity and vulnerability of urban water systems in Arizona reveals that managers are more concerned about factors such as population growth projections, economic trends, and revenue flows. Reliance on groundwater resources in many cases obscures recognition of any direct impact of precipitation on water supply. Given the low level of perceived climate risk among many providers interviewed for this study, it would seem unlikely that climate information would be needed. However, pockets of sensitivity and vulnerability to climatic impacts do exist in the four study areas covered in this study.
This Technical Data notebook has been prepared for a Letter of Map Revision application for a portion of the Trails End Wash located in Pima County, Arizona. The objective of the TDN and LOMR submission is to provide regulatory discharge rates and floodplain limits along the Trails End Wash using better topographic, hydrologic, and hydraulic data.
This Technical Data notebook has been prepared for the Picture Rocks area located in Pima County, Arizona. The objective of the TDN is to provide regulatory discharge rates and identify floodplain hazard area along in the Picture Rocks study area using better topographic, hydrologic, and hydraulic data.
This Technical Data notebook has been prepared for a Letter of Map Revision application for a portion of the Del Cerro Wash located in Pima County, Arizona. The objective of the TDN and LOMR submission is to provide regulatory discharge rates and floodplain limits along the wash using better topographic, hydrologic, and hydraulic data.
This Technical Data notebook has been prepared for the Casas Adobes Wash located in Pima County, Arizona. The objective of the TDN is to provide discharges and floodplain limits along the CSA using better topographic, hydrologic, and hydraulic data. This is a local study and has not been submitted to FEMA.
