The improvements associated with the stream restoration project were constructed in phases, and resulted from course modifications necessary to abandon an existing entrance ramp onto I-70, extend Business Loop 70 to serve as an outer road to I-70 & US Route 63, and providing a new connection to Conley Road. Property takings associated with the improvements required the relocation and redesign of several holes on the existing Columbia Country Club golf course, significant coordination with the US Army Corp of Engineers and other stakeholders concerned with the impacts to Hinkson Creek, preparation of a FEMA Conditional/Letter of Map Revision (C/LOMR).
As part of the golf course hole relocation, several stretches of existing stream required protection from construction activities, bank stabilization, or full relocation and restoration. An evaluation of the stream characteristics identified a number of deficiencies including bank erosion, channel meandering, drainage structures that weren’t operating as designed, etc. Measures to mitigate these issues were recommended and constructed over a two-year period by a combination of contractors and course maintenance staff. Features included reestablishing drainage systems, planting of native vegetation to promote bank stabilization and water quality improvement, construction of water control structures (concrete, rock) to reduce flow velocity and create riffle pools, etc.
