Client: Flood Control District of Maricopa County

Wickenburg ADMS/ADMP

Hoskin Ryan is currently contracted by the Flood Control District of Maricopa County to revise 100 linear miles of the existing FEMA floodplain delineations of tributary watercourses to the Hassayampa River and Sols Wash, within the Town of Wickenburg and surrounding area. There has been significant growth and changes to the watershed since the previous study. In addition, there have been advancements in the technology used to identify flood hazards. Precipitation data has changed and more accurate digital topography is available. The major tasks for the project include: survey, geology, geotechnical, public involvement, hydrology, hydraulics (HEC-RAS models and 2-Dimensional models are used to analyze the 100-year base flood elevations and resultant floodplain delineations), sediment analysis, floodplain delineation, planning studies and a FEMA submittal. An evaluation and prioritization will be made of existing and potential flood prone areas and their solutions, during the ADMP phase.
