Tempe Canal Floodplain Delineation Study

Hoskin Ryan performed a floodplain delineation study revising the existing Zone A floodplain limits along the east side of Tempe Canal. Comprehensive HEC-1 hydrologic modeling was created for the approximately 26-square-mile urban watershed, spanning north and south of US60 within the City of Mesa. The project included hydrologic and hydraulic modeling, data collection, report documentation and elevation certificates. The HEC-1 model included detailed split flow and storm drain diversions. Additionally, Finished Floor Certifications were completed for over 250 structures either within or close proximity to the revised floodplain. Hoskin Ryan successfully completed this project three months ahead of schedule and under budget.
Project Requirements / Unique Characteristics:
