dc.descriptionThe principal objective of this study is to evaluate the western piedmont of the McDowell Mountains to determine which areas may be subject to alluvial-fan flooding. The McDowell Mountains piedmont (MMP) is the gently sloping plain that lies west of the McDowell Mountains and extends into north Phoenix. An alluvial fan flooding methodology mandated by the Federal Emergency Agency (FEMA) has been used to delimit 100-year floodplains in this area. In this report we consider whether the areas on the MMP determined by FEMA to be active alluvial fans, and therefore within the 100- year floodplain, are consistent with evidence of flooding recorded in the geomorphology of the piedmont. This study has been conducted as part of a formal appeal of the preliminary flood insurance rate maps (FIRMs) released for this area (FEMA, 1991b) by the City of Scottsdale, the City of Phoenix, and the Flood Control District of Maricopa County.
