Freese and Nichols provided engineering services to rehabilitate a 500-foot-long reach of Tributary WT-3 to Tannehill Branch Creek in southeast Austin. Upstream development resulted in increased flow through the neighborhood causing bank failures and downcutting of the channel bottom. Due to the City's desired schedule for starting construction, this was a fast-track project.
Freese and Nichols prepared a preliminary design report that evaluated four alternatives and prepared construction and permitting documents for the selected alternative. Freese and Nichols also conducted field investigations including surveying and geotechnical drilling and testing, updated the City's existing hydrologic models and developed new hydraulic models, prepared a preliminary design report, drafted construction documents for use in permitting and bidding, and prepared a U.S. Army Corps of Engineers Nationwide Permit Application for construction.
