PHOENIX, AZ (July 28, 2010) - Stantec was selected by the Flood Control District of Maricopa County to undertake an extensive study of the Gillespie/Woolsey watershed. This effort will identify and mitigate flood hazards for the area through analysis and development guidelines. Spanning 148 square miles southwest of the Phoenix metropolitan area, the watershed contains a sizeable amount of agricultural land, key infrastructure and public facilities, and portions of the Sonoran Desert National Monument. The two-year study will provide a high level of flood safety for area residents by establishing guidelines to address current and potential flood hazards in the watershed. The contract for Stantec is anticipated to be between $1.2 and $1.6 million.

The study stemmed from a request for assistance from the Woolsey Flood Protection District. The study area includes portions of unincorporated Maricopa County, and the towns of Gila Bend and Buckeye. Stantec’s study data will be an integral part of first phase of the Gillespie Area Drainage Master Study conducted by the Flood Control District of Maricopa County, the publicly-funded agency that identifies, remediates and regulates flood hazards in unincorporated areas and 12 incorporated communities in the county.

Working from its Phoenix office, Stantec’s scope of professional engineering services will include hydrologic and hydraulic analysis, identification and quantification of drainage problems and flood hazards, Federal Emergency Management Agency (FEMA) floodplain delineations, surveying, sedimentation and channel lateral migration evaluation, public outreach, stakeholder coordination, and establishment of public safety guidelines to address the identified flooding.

About the technical strategy
Among the innovative techniques to be employed by Stantec is its use of the FLO-2D modeling software, which will deliver an integrated river and floodplain model. Using the software, Stantec will complete flood routing hydrologic and hydraulic models that will evaluate the impacts of manmade and natural features such as diversions structures and alluvial fans on flooding conditions.

About Stantec’s Local Flood Control Expertise
The Flood Control District of Maricopa County’s study is the most recent in a long list of locally based projects supported by Stantec engineers to serve the evolving needs of the greater Phoenix area. With nearly 20 years of local expertise in flood control consultation, Stantec applies knowledge and technology to deliver and manage solutions. These infrastructure solutions are collaboratively developed from the firm’s established local design experience, and its knowledge of specialized modeling and technologies, such as integrating GIS, topographic mapping, and two dimensional computer modeling of storm runoff.
