S&我公司. 和市政工程 & 这公司. | Chattanooga’s Big Dig | Chattanooga, TN | City of Chattanooga

Chattanooga’s Big Dig, jointly submitted with Civic Engineering and Information Technologies, Inc. (公民) won the People’s Choice Award and an Honor Award in the Environmental Category for large projects. Managed by Rick Bruce, PG, (S&ME) and Philip Nelson, PE, (公民), the City of Chattanooga took action To prevent a catastrophic failure of their stormwater infrastructure and potential water contamination from a former landfill, the City requested Civic to redesign the storm conveyance in the historic St. Elmo area of the city. Civic developed a plan to re-route the existing storm infrastructure around the Wheland Foundary Landfill, 和S&ME was contracted to develop a comprehensive Soil and Groundwater Management Plan for management of excavated materials, due to the history of area soil and foundry sand contamination. The new storm drainage is designed to accommodate a 100-year storm event for an 1,100-acre drainage area. The discovery of contaminated soils complicated the project and brought in additional stakeholders. The new infrastructure has been designed with expansion in mind to pave the way for future development of the area in conjunction with the planned extension of the Chattanooga Riverwalk.
