Flecha Caida Estates Floodplain Mapping Study

Flooding and erosion within the Flecha Caida Ranch Estates #9 subdivision during the 2007 summer monsoon season raised the concerns of numerous homeowners who were not aware of the historical drainage problems inherent to the area. The Pima County Regional Flood Control District commissioned this study to (1) address the impact of recent improvements in the drainage area upstream of the study area; (2) provide updated flood-hazard mapping for the area from just upstream of Calle del Pantera to North Flecha Drive, which is where the Federal Emergency Management Administration (FEMA) flood plain for the Valley View Wash begins; and (3) identify mitigation measures that could be implemented by the affected homeowners to address their flood/erosion hazards.
