Discussion of Stream Restoration Feasibility Study (COF Contract No. 2014-0119) Results for Jordan Branch in the Meadow at Cool Springs subdivision (Sliders Knob)
body
Purpose
The purpose of this memorandum is to provide the results of the Stream Restoration Feasibility Study for Jordan Branch in The Meadow at Cool Springs subdivision to the Board of Mayor and Aldermen (BOMA) for further discussion.
Information & Discussion
For several years, the City of Franklin has received complaints from residents about erosion of Jordan Branch, which flows behind several houses in The Meadow at Cool Springs subdivision. The stream originates near the city limits between Brentwood and Franklin, directly adjacent to the Nashville Golf & Athletic Club. The Tennessee Department of Environment and Conservation (TDEC) lists Jordan Branch as impaired for siltation.
On June 10, 2014, the BOMA approved a professional services agreement (COF Contract No. 2014-0119) with Civil and Environmental Consultants, Inc. (CEC) for an amount not to exceed $21,500. The purpose of this feasibility study was to determine potential ways of mitigating the eroding stream channel before investing in a field survey and detailed engineering design. In December 2014, City staff received the final report for this feasibility study.
In November 2014, CEC organized a site visit with TDEC, the U.S. Army Corps of Engineers (USACE) and City staff. The report contains several potential solutions, such as: channel armoring, modification of the existing stream channel, construction of a detention basin, piping the entire stream, or some combination of solutions.
One of the next steps in determining the best solution would involve meetings with the project stakeholders, such as The Meadow at Cool Springs Homeowner's Association, the Nashville Golf and Athletic Club, TDEC, and USACE to present the potential solutions listed in the feasibility study and to solicit feedback from the stakeholders. Following this meeting, staff will develop options and detailed cost estimates to obtain direction from the Board of Mayor and Aldermen.
Recommendation
At this point in the project life cycle, City staff requests feedback from the BOMA about this project.
