Project Highlights

S&ME was retained to provide stream and wetland permitting (401/404), design, and monitoring for approximately 2,660 feet of perennial and intermittent stream impacts and 1.67 acres of wetland impact as part of the construction of large retail development.

The design plan included onsite and offsite mitigation areas. Approximately 1,320 feet of perennial stream was created on site. Shear stresses were calculated for the design channel and tested for compatibility with the shale bed material left by the site grading conditions. Approximately 525 feet of perennial channel, 850 feet of intermittent channel, and 6.7 acres of wetland were created at the offsite mitigation area. Due to the TVA  power lines traversing overhead the planting plan was developed from desirable native herbaceous plants that would be planted in the constructed low marsh areas under the power lines, since larger woody species would be problematic.

The onsite mitigation area was completed in the spring of 2005 and the offsite mitigation area was completed in the spring of 2006. S&ME is currently providing the annual monitoring for both mitigation sites. To date, both mitigation sites are meeting their design goals.
