Low Impact Development – West Park Equalization Basin


Metro Water Services (MWS) provides water and wastewater services to over 177,000 accounts in the greater Nashville, TN area.  As part of MWS’ Clean Water Nashville (CWN) program, Wilmot was chosen as a member of the design team to incorporate green infrastructure and demonstrate the sustainable design guidelines at Metro Nashville’s West Park.


As part of the design team for one of the first CWN projects, Wilmot took the initiative to “stress test” the sustainable design standards through workshops and design meetings.  Wilmot exceeded the design guidelines with several additional design options, only two of which were eliminated from consideration for constructability or maintenance reasons.  Additional design constraints include a floodplain, floodway, and stream buffer adjacent to the construction site, residential neighbors, uncompensated fill issues, and poor grading conditions.  Wilmot is also developing the cost and benefits of solar-ready design, reforestation, rainwater collection, bioswales, vegetated buffers, and 100% management of site storm water.
