The Flood Protection Planning Study encompasses approximately 297 square miles; a significant size watershed area that predominately drains into the Arroyo Colorado waterway. The Flood Protection Planning Study is intended to provide a detail evaluation of existing drainage infrastructure and from a regional approach determine the effectiveness of how these drainage systems interconnect to convey storm water to the ultimate outfall point. The FIF grant provides for the creation of hydraulic models, updates to existing hydraulic models, the placement of streamflow monitoring stations, and planning documents that identify optimal flood protection capital improvement projects.

Objectives include, but are not limited to the following:• Review and incorporation of all existing drainage plans, studies, or other drainage related

program guidance relative to the study area;• Updated inventory, and where applicable or necessary, field survey of existing drainage

structures, confluences and other drainage appurtenances;• Development and/or update of new hydrologic and hydraulic models;• Mapping of the 100-year and 500-year flood plains based on the latest data and information;• Updating drainage criteria for the study area;• Identification of flood prone areas and infrastructure;• Development of real-time flood monitoring and warning systems;• Development of structural and non-structural flood control projects.
