F-2. AMENDMENT TO IGA FOR DESERT SOIL HYDRAULIC CHARACTERIZATION PROJECT Approve Amendment No. 1 FCD 2008A014A to Intergovernmental Agreement (IGA) FCD 2008A014, between the Nevada System of Higher Education, Desert Research Institute (DRI) and the Flood Control District of Maricopa County (District) to extend the period of this IGA to allow sufficient time for DRI to complete the review and revision process of the final report. This is a No Cost Amendment. Agreement FCD 2008A014 was approved by the Board of Directors on March 18, 2009 (C-69-09-050-3-00). This IGA Amendment is effective the date it is fully executed by all parties. The IGA shall terminate on February 26, 2010. The DRI will be responsible for completion of all work items under this IGA. The purpose is 1) to evaluate runoff potential and physically measure infiltration rates on a test watershed in Maricopa County, 2) to develop Green and Ampt parameters using the measured data and compare the results with the District’s current method and a new method for estimating Green and Ampt parameters developed by the USDA Agricultural Research Service, and 3) to apply the developed parameters to the test watershed and two (2) other similar watersheds for which the District has developed rainfall-runoff data and simulation models for storms of record. The results are expected to be published and may be used in refining the District’s Drainage Design Manual. This item impacts all Supervisor Districts 1, 2, 3, 4, and 5. (C-69-09-050-3-01)
