Projects

Franklin County, TN

Engineering services were provided to the Tennessee Stream Mitigation Program (TSMP) for restoration of 4,835 linear feet of two cobble/gravel bed channels in the Interior Plateau Ecoregion, and implementation of a stormwater BMP along a contributing tributary. Robinson Creek has a drainage area of 13.7 miles and was designed as a Priority II B/4 and C/4 type channel. The channel’s bankfull elevation was incised over 3 feet below the top of existing ground. The restoration concept included lowering the existing slope to allow for the bankfull elevation to be raised through the site. Taylor Creek has a drainage area of 7.6 miles and was designed as a Priority I and II C/4 type channel. The restored alignment was moved from its existing location to the low point of the valley to allow all watershed drainage to access the channel. Structures such as rock cross-vanes, A-vanes, log vanes, log sills, and rootwads were installed as a means of slope and grade control, bed form diversity, and habitat enhancement. A stormwater wetland was constructed on a tributary to Taylor Creek to filter nutrients from an upstream cattle operation and adjacent agricultural fields. The project was assessed, designed and constructed in less than 9 months.

Services included:
• assessment,
• design,
• engineering, and
• construction management services.
