 Sevenmile Creek Feasibility Study


US ARMY CORPS OF ENGINEERS BUILDING STRONG®

 

AUTHORIZATION: House Committee on Transportation and Infrastructure adopted 7 December, 2005.

TYPE OF PROJECT: General Investigations Flood Risk Management and Ecosystem Restoration Feasibility Study.

LOCATION: Mill Creek drains southeastern Davidson County and northeastern Williamson County. It originates two miles south of Nolensville and flows northward to its confluence with the Cumberland River, just four miles upstream of downtown Nashville. The watershed is 108 square miles with 72 in Davidson County and 36 in Williamson County.

CONGRESSIONAL INTEREST: Alexander (TN), Corker (TN), Cooper (TN-05)

NON-FEDERAL SPONSOR: Nashville; Metro Water Services

BACKGROUND:

·   Sevenmile Creek remains in the I business line, Mill Creek was moved to CAP program for implementation. Mill Creek project began with PPA execution on December 15, 2017.

·   The May 2010 flood event interrupted what had been a study with an ecosystem restoration focus, and the study was re-initiated in February 2013 with the sole purpose of flood risk management. The feasibility report was completed in October 2015.

 

IMPORTANCE:  Mill Creek was severely flooded during the record May 2010 flood events, as hundreds of homes and businesses were left damaged in the wake of the flood in addition to two flood related fatalities. The prior flood of record, May 1979, also resulted in two fatalities. There have been three major flood events in Mill Creek, since 1979. Hundreds of homes in the watershed endure systemic flood damages.

STATUS:  The district successfully completed final review of the report via the Civil Works Review Board on 28 May 2015.  The Chief of Engineers signed the final report on 16 October 2015. The report received OASA and OMB approvals and was submitted to Congress on 30 March 2016. The report recommends the buyout and permanent relocation of 89 residential structures along with two major construction projects; Ellington detention basin along Sevenmile Creek, and the Briley bridge and channel modification project for the middle reach of Mill Creek (shown on reverse map). The 2016 Water Infrastructure Improvements for the Nation (WIIN) Act authorized the Sevenmile Creek project for construction and directed LRN to implement the Mill Creek Main Stem portion of the project in the CAP Section 205 program.
