Bay Flat Road Ditch Excavation Project
NOE - Notice of Exemption
The project would include removal of sediment and invasive plants at six adjacent locations along Bay Flat Road. The ditches currently receive storm water from the road and hillslope seeps, and exhibit wetland swale characteristics. The project will include excavation of the ditch to the design depth of one foot and 3.5 feet wide. Excavation will not permanently change hydrology of adjacent wetlands, but will allow for greater capacity to address current flooding since the ditches have not been cleared since the 1990s. The ditches should continue to exhibit wetland swale characteristic with regrowth of the native plants and thus, impacts to 0.03 acres of wetlands will be temporary.
