Clean Water Act Section 404 Permit | Wetland Delineation

Clean Water Act Section 404 Permit

The Clean Water Act Section 404  was passed by the Congress in 1977 to protect the physical, biological and chemical quality of waters of the US. Section 404 of the Clean Water Act requires a permit to place any fill material in the nation’s rivers, streams, pond, lakes and wetlands.

Wetland Delineation

Wetland Delineation for Clean Water Act Section 404 Permit In order to determine Clean Water Act Section 404 needs for a project a wetland delineation  is often one the first steps required to determine the exact boundary and types of wetland present on a project site. Wetland delineations are conducted in accordance with the 1987 Corps of Engineers Wetland Delineation Manual and Regional Supplements. This approach requires positive evidence of hydrophytic vegetation, hydric soils and wetland hydrology for a determination that an area is considered wetland. ERC staff is highly trained and experienced in wetland delineations throughout Colorado and the Rocky Mountain region as well as both east and west coastal regions and alpine tundra of Alaska.

ERC provides wetland delineations for projects ranging from small single-family home sites to large scale regional projects well in excessive of 10,000-acres. As part of ERC’s wetland delineation services complete report documentation, GPS field mapping, GIS map products and functional assessments with such methodologies as FACWet, WET and HGM can be provided.
