White Tanks FRS No. 3 Outfall Channel – Preliminary and Final Design

Hoskin Ryan provided survey, preliminary, and final design services for this 5-mile long outfall channel facility project. The earthen channel features bridge structures at nine major roadways and 18 grade control structures. The channel and structures integrated aesthetic design elements, including landscaping, stepped spillways, form liners, gravel mulch and landscaped mounding. While doing the preliminary design, alternative, alignments, right-of-way configuration and retention alternative were evaluated. Challenged to identify alternatives with respect to hydrologic and hydraulic effectiveness, existing facilities, construction and right-of-way, Hoskin Ryan provided value analysis early in the design process and developed the preferred alternative in two months.
