Cleveland Municipal Airport Creek Relocation

S&ME was contracted by the PDC Consultants to address impacts from the construction of the airport for Cleveland, Tennessee. The proposed location would require impacts to Little Chatata Creek due to the alignment of the proposed runway expansion. S&ME developed a design for the onsite realignment of approximately 3,200 feet of stream channel. In addition, S&ME developed offsite mitigation for approximately ten acres of wetlands.

The realignment includes a 3-span stream crossing beneath the runaway. Offset elevations maintain continuity of channel and floodplain flows. Services included wetland delineations, morphological assessments, a no-rise certification, stream relocation design services, stormwater management support, wetland mitigation planning, permitting services, Phase III archaeological data recovery, and construction observation. S&ME performed regulatory coordination with TDEC, USACE, and TVA to address permitting and stakeholder concerns.

S&ME utilized natural channel design techniques modified  to address FAA requirements. The project also required extensive modeling of the proposed stream relocation. Flood elevation calculations utilized USACE HEC-RAS software. S&ME supported the civil design contractor throughout the bid process by preparing technical specifications, bid forms, and bid package addenda.
