Section 404 of the Clean Water Act

Resources that Support Mitigation Regulations under CWA Section 404

This is a partial list of websites of materials (mitigation bank templates, checklists, etc.) that comply with and/or support the mitigation regulations. This list is provided for informational purposes only and is not an endorsement of any particular document or approach. While templates, checklists, or agreements developed for purposes of compensatory mitigation for the Corps Regulatory Program need to comply with the mitigation regulations, the regulations also provide substantial flexibility for districts to account for regional differences in aquatic resource types, functions, and services.
