Wetland Delineation

This week we performed a wetland delineation in Whitley County, Kentucky to fulfill requirements under Section 404 of the Clean Water Act.

The wetland delineation in Whitley County, Kentucky was conducted by BSC personnel in support of the requirements of Section 404 of the Clean Water Act (CWA). Field surveys for the following determination were conducted in accordance with the 1987 United States Army Corps of Engineers (USACE) Wetlands Delineation Manual (USACE, 1987) and the Final Regional Supplement for the Piedmont and Eastern Mountains Region (USACE, 2012).

According to USACE “This Regional Supplement is part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland delineation procedures. Regional differences in climate, geology, soils,hydrology, plant and animal communities, and other factors are important to the identification and functioning of wetlands. The regional supplement was finalized in 2012 and covers all or portions of the District of Columbia and 20 states: Alabama, Arkansas, Delaware, Georgia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, North Carolina, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Virginia, and West Virginia” (USACE 2012).

The determination within our report is subject to review and approval by the Nashville District of the USACE. As requested by the Nashville District USACE only the area within the vicinity of the proposed work was evaluated for the wetland delineation. As indicated in our report there was a small area that appeared to meet the soils, hydrology, and vegetation characteristics for wetlands as defined by USACE. See more of our services here.
