White Tanks FRS No. 3 Outfall Channel, Preliminary Design – Buckeye, AZ
Hoskin Ryan was selected to identify cost effective alternatives to carry outflow from the dam, intercept local drainage and mitigate existing floodplains. Six alternatives were evaluated for hydrologic and hydraulic effectiveness, utilization of existing facilities, construction and ROW costs. Hydrology was performed using HEC-1 for future conditions, both with and without the project, and results were documented in a Preliminary Design Report. The recommended alternative was developed into 30% Design Plans for this 5-mile long outfall channel identifying all major design features. Hoskin Ryan was later selected for Value Analysis, Final Design, Post-Design and Construction Services.
