AT&SF Railroad Channel & Basin
Hoskin Ryan provided Alternatives Analysis and 15% Design Plans for the AT&SF Channel and Basin Candidate Assessment Report. Between Reems and El Mirage Roads, the channel will provide flood mitigation and a regional outfall for the Northern Parkway. Nine alternative drainage concepts and alignments were assessed for their hydrologic and hydraulic effectiveness and for their multi-use recreational potential. Hoskin Ryan hosted the stakeholder meetings and provided a presentation and outline of alternatives for review and refinement.
Preliminary channel design plans and profiles were prepared for the recommended alternative. All work products were completed on time in a very short time frame without change orders.
