86. AMENDMENT TO IGA WITH THE UNITED STATES GEOLOGICAL SURVEY FOR WATER RESOURCES INVESTIGATION Approve the amendment to the Intergovernmental Agreement (IGA) FCD 2020A015A, between the United States Geological Survey [Agreement #20ZFJFA3000 (USGS)] and the Flood Control District of Maricopa County (District), to extend the study to September 30, 2021, for collection and analysis of ground and surface water quality and quantity data on lower Gila River. The amendment shall also increase FCD’s total costs of the IGA by $90,000 and will not exceed $180,000. The USGS contributing the remaining funding up to $180,000. Payments from the District are to be made quarterly. To reduce the flood hazards in the Gila River, one of the strategies is to remove the dense non-native salt cedar (i.e. tamarisk) from the river. Removing salt cedar from the Gila River corridor and replacing it with native vegetation will help prevent salt cedar from growing back and may reduce the extent of the floodplain. The survivability of cottonwoods, willows, and desert shrubs is dependent upon soil chemistry and water quality and quantity. Such soil and water data are lacking within the Gila River. Monitoring soil and water under this agreement will provide data that can be used by the District and others to strategically target areas where revegetation efforts have the highest potential for success. Partnering with the USGS allows the District to leverage the USGS’s funding and expertise on water quality and monitoring to obtain this data on the Gila River. This agenda item impacts Supervisorial Districts 4 and 5. (C-69-20-027-3-01)
